{{Short description|Form of social engineering}}
In [[computing]], '''phishing''' is the act of attempting to fraudulently acquire through deception sensitive personal information such as [[password]]s and credit card details by masquerading in an official-looking email, IM, etc. as someone trustworthy with a real need for such information. It is a form of [[social engineering (computer security)|social engineering]] attack. ([http://purl.org/net/tbc/misc/phish001.htm See an example].)

'''Phishing''' is a form of [[Social engineering (security)|social engineering]] and a [[scam]] where attackers deceive people into revealing [[Information sensitivity|sensitive information]]<ref>{{Cite journal |last1=Jansson |first1=K. |last2=von Solms |first2=R. |date=2011-11-09 |title=Phishing for phishing awareness |url=http://www.tandfonline.com/doi/abs/10.1080/0144929X.2011.632650 |journal=Behaviour & Information Technology |language=en |volume=32 |issue=6 |pages=584–593 |doi=10.1080/0144929X.2011.632650 |s2cid=5472217 |issn=0144-929X}}</ref> or installing [[malware]] such as [[Computer virus|viruses]], [[Computer worm|worms]], [[adware]], or [[ransomware]].

The term "phishing" was first recorded in 1995 in the [[Security hacker#Cracker|cracking]] toolkit [[AOHell]], but may have been used earlier in the hacker magazine ''[[2600: The Hacker Quarterly|2600]]''.<ref name="ollmann">{{cite web | author=Ollmann, Gunter | title=The Phishing Guide: Understanding and Preventing Phishing Attacks | work=Technical Info | url=http://www.technicalinfo.net/papers/Phishing.html | access-date=2006-07-10 | archive-date=2012-06-29 | archive-url=https://archive.today/20120629023934/http://www.technicalinfo.net/papers/Phishing.html | url-status=live }}</ref><ref name="thebigphish">{{cite journal |last1=Wright |first1=A |last2=Aaron |first2=S |last3=Bates |first3=DW |title=The Big Phish: Cyberattacks Against U.S. Healthcare Systems. |journal=Journal of General Internal Medicine |date=October 2016 |volume=31 |issue=10 |pages=1115–8 |doi=10.1007/s11606-016-3741-z |pmid=27177913|pmc=5023604 |doi-access=free |issn = 0884-8734 }}</ref><ref name="AOLUnderground">{{cite podcast | title=AOL Underground | url=https://anchor.fm/aolunderground/episodes/Da-Chronic--Creator-of-AOHell-and-Automated-Phishing-e1ic74b/a-a7tfsc3 | website=aolunderground.com | publisher=Anchor.fm | host=Stonebraker, Steve | date=January 2022
The term was coined in the mid [[1990s]] by [[cracker (computing)|cracker]]s attempting to steal [[AOL]] accounts. An attacker would pose as an AOL staff member and send an [[instant message]] to a potential victim. The message would ask the victim to reveal his or her password, for instance to "verify your account" or to "confirm billing information". Once the victim gave over the password, the attacker could access the victim's account and use it for criminal purposes, such as [[spam (electronic)|spam]]ming.

There is also an [[Ireland|Irish]] [[Internet Relay Chat|IRC]] network called [[Phishy]], although it predates the use of that term for anything illegal.
 
== Usage Types==
The term "phishing" is sometimes said to stand for '''password harvesting fishing''', though this is likely a [[backronym]]. The cracker community tends to use creative spellings as a sort of jargon, and coinages such as [[warez]] have even escaped into more mainstream usages.
 
===Email phishing===
"Phishing" attacks are named so because the senders are “fishing” for recipients’ personal information. The substitution of "ph" for "f"” is according to the U.S.-based Anti-Phishing Working Group said to be a nod to an early form of hacking known as [[phreaking]], which refers to gaining access to telephone networks. Still other theories accredit the term "phishing" to originate from the name "Brien Phish" who was the first to allegedly use psychological techniques to steal credit card numbers in the 1980s. Others believe that "Brien Phish" was not a real person but a fictional character used by scammers to identify each other. Another, more recent theory credits the nature of the attacks, in which one is [[fishing]], metaphorically, for an unsuspecting user's information.
Phishing attacks, often delivered via [[email spam]], attempt to trick individuals into giving away sensitive information or login credentials. Most attacks are "bulk attacks" that are not targeted and are instead sent in bulk to a wide audience.<ref name="verizon2019">{{cite web |title=2019 Data Breach Investigations Report |url=https://www.phishingbox.com/assets/files/images/Verizon-Data-Breach-Investigations-Report-DBIR-2019.pdf |website=PhishingBox |publisher=Verizon Communications |access-date=21 March 2021}}</ref> The goal of the attacker can vary, with common targets including financial institutions, email and cloud productivity providers, and streaming services.<ref name="2019cfs">{{cite journal |last1=Furnell |first1=Steven |last2=Millet |first2=Kieran |last3=Papadaki |first3=Maria |title=Fifteen years of phishing: can technology save us? |journal=Computer Fraud & Security |date=July 2019 |volume=2019 |issue=7 |pages=11–16 |doi=10.1016/S1361-3723(19)30074-0 |s2cid=199578115 |access-date=21 March 2021 |url=https://www.researchgate.net/publication/334551961}}</ref> The stolen information or access may be used to steal money, install [[malware]], or spear phish others within the target organization.<ref name="the big phish">[https://www.fbi.gov/how-we-can-help-you/scams-and-safety/common-frauds-and-scams/spoofing-and-phishing Spoofing and Phishing] Federal Bureau of Investigation</ref> Compromised streaming service accounts may also be sold on [[darknet market]]s.<ref name="atlanticnflx">{{cite web |last1=Waddell |first1=Kaveh |title=The Black Market for Netflix Accounts |url=https://www.theatlantic.com/technology/archive/2016/02/the-black-market-for-netflix-accounts/462321/ |website=The Atlantic |access-date=21 March 2021 |language=en |date=11 February 2016}}</ref>
 
This type of [[Social engineering (security)|social engineering]] attack can involve sending fraudulent emails or messages that appear to be from a trusted source, such as a bank or government agency. These messages typically redirect to a fake login page where users are prompted to enter their credentials.
Today, online criminals put phishing to more directly profitable uses. Popular targets are users of [[online banking]] services, and [[auction]] sites such as [[eBay]]. Phishers usually work by sending out [[e-mail spam]] to large numbers of potential victims. These direct the recipient to a [[Web page]] which ''appears'' to belong to his online bank, for instance, but in fact captures his account information for the phisher's use.
 
=== Spear phishing<span class="anchor" id="spearphishing"></span> ===
Typically, a phishing email will appear to come from a trustworthy company and contain a subject and message intended to alarm the recipient into taking action. A common approach is to tell the recipient that his account has been deactivated due to a problem and to take action to re-activate the account. The user is provided with a convenient link in the same email that takes the email recipient to a [[forgery|fake]] webpage appearing to be that of a trustworthy company. Once at that page, the user enters his personal information which is then captured by the fraudster.
Spear phishing is a targeted phishing attack that uses personalized messaging, especially e‑mails,<ref>{{cite web |title=Spear phishing |website=Windows IT Pro Center |url=https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/phishing#spear-phishing |via=docs.microsoft.com |access-date=4 March 2019 }}</ref> to trick a specific individual or organization into believing they are legitimate. It often utilizes personal information about the target to increase the chances of success.<ref>{{cite web |last=Stephenson |first=Debbie |title=Spear phishing: Who's getting caught? |website=Firmex.com |url=http://www.firmex.com/blog/spear-phishing-whos-getting-caught/ |access-date=July 27, 2014 |date=2013-05-30 |archive-date=2014-08-11 |archive-url=https://web.archive.org/web/20140811102334/http://www.firmex.com/blog/spear-phishing-whos-getting-caught/ |url-status=live }}</ref><ref>{{cite news |title=NSA/GCHQ hacking gets personal: Belgian cryptographer targeted |date=3 February 2018 |magazine=Info Security magazine |url=https://www.infosecurity-magazine.com/news/nsagchq-hacking-gets-personal-belgian/ |access-date=10 September 2018 }}</ref><ref>{{cite news |last=Leyden |first=John |date=4 April 2011 |title=RSA explains how attackers breached its systems |newspaper=[[The Register]] |place=UK |url=https://www.theregister.co.uk/2011/04/04/rsa_hack_howdunnit/ |access-date=10 September 2018 }}</ref><ref>{{cite news |last=Winterford |first=Brett |date=7 April 2011 |title=Epsilon breach used four-month-old attack |url=https://www.itnews.com.au/news/epsilon-breach-used-four-month-old-attack-253712 |access-date=10 September 2018 |via=itnews.com.au }}</ref> These attacks often target executives or those in financial departments with access to sensitive financial data and services.

== URL spoofing ==
There are several types of URL spoofing [http://www.gerv.net/hacking/security/phishing.html]:
# An IP address, e.g. [http://192.168.1.1/ http://192.168.1.1/] <br> This relies on the user ignoring the URL bar completely, or being confused by its complexity.
# A completely different ___domain, e.g. [https://www.randomdomain.com/ https://www.randomdomain.com/] <br> This relies on the user just not looking at the ___domain at all.
# A plausible-sounding but fake ___domain, e.g. [https://www.paypal-secure.com https://www.paypal-secure.com] <br> This relies on the user not knowing their exact destination, which is made easier and more plausible by the fact that many real companies use a bewildering variety of ___domain names for their different branches and services instead of a logical structure of subdomains of its main ___domain.
# A visible-to-the-eye letter substitution, e.g. [https://www.paypa1.com https://www.paypa1.com] <br> This relies on the user not looking too closely at individual letters.
# An invisible letter substitution ([[punycode]] attack) by making use of fault in [[Internationalized ___domain names|IDN]], e.g. [https://www.xn--pypal-4ve.com https://www.xn--pypal-4ve.com] <br> This sort are currently almost undetectable on some browsers.
# An address with username that looks like a ___domain name, e.g. [http://www.paypal.com@www.evil.com http://www.paypal.com@www.evil.com]
# An address that uses [[wildcard DNS record]] characters to disguise the ___domain name [http://news.netcraft.com/archives/2005/03/07/phishers_use_wildcard_dns_to_build_convincing_bait_urls.html]. Some examples include:
#:http://barclays.co.uk|snc9d8ynusktl2wpqxzn1anes89gi8z.dvdlinKs.at/pgcgc3p/
#:http://barclays.co.uk|YJ3EMOHOqljQ8J5oW2ZKyTaRMQOahSWaxTrFTEQK9l9VVQj6jDtyq10d24r2h0bijh2
#:http://barclays.co.uk|34fdcb4rvdnp9phxbahhvbs6l56a2uyx%2edivxmovies%2ea%74/41pvaw3/
Checking the URL in the address bar of the browser may not be sufficient, as, in some browsers, that can be faked as well. However, the file properties feature of several popular browsers may disclose the real URL of the fake webpage.
 
A study on spear phishing susceptibility among different age groups found that 43% of youth aged 18–25&nbsp;years and 58% of older users clicked on simulated phishing links in daily e‑mails over 21&nbsp;days. Older women had the highest susceptibility, while susceptibility in young users declined during the study, but remained stable among older users.<ref>{{cite journal |last=Alkhalil |first=Z. |year=2021 |title=Phishing attacks: A recent comprehensive study and a new anatomy |journal=Frontiers in Computer Science |volume=3 |doi=10.3389/fcomp.2021.563060 |doi-access=free}}</ref>
== Additional attack methods ==
Besides URL spoofing, it is also possible for the attacker to utilize the bank/service's own scripts against them. These attacks are particularly problematic because they actually direct the user to sign in at their bank/service's own web pages, where everything from the URL to the SSL certificate are correct.
Example: [https://signin.ebay.com/ws/eBayISAPI.dll?SignIn&UsingSSL=1&pUserId=&co_partnerId=2&siteid=0&ru=http%3A%2F%2Fcgi4.ebay.com%2Fws%2FeBayISAPI.dll?MfcISAPICommand%3dRedirectToDomain%26DomainUrl=http%3A%2F%2F127.0.0.1%2FeBayISAPI.php&pageType=1883]
(address changed to protect the reader)
While clicking on this link brings you to eBay's site to log in, it then forwards the authenticated request to another ___domain/server, where the hacker's harvesting script is potentially waiting for this information.
 
=== Voice phishing (Vishing) ===
If you are contacted about an account needing to be "verified," you should contact the company directly, or type in the address for their webpage.
{{anchor|Vishing}}
{{Main article|Voice phishing}}
[[Voice over IP]] (VoIP) is used in vishing or voice phishing attacks,<ref name="vishing">{{cite book |last1=Griffin |first1=Slade E. |last2=Rackley |first2=Casey C. |title=Proceedings of the 5th annual conference on Information security curriculum development |chapter=Vishing |date=2008 |pages=33–35 |doi=10.1145/1456625.1456635|isbn=9781605583334 }}</ref> where attackers make automated phone calls to large numbers of people, often using [[Speech synthesis|text-to-speech]] synthesizers, claiming fraudulent activity on their accounts. The attackers spoof the calling phone number to appear as if it is coming from a legitimate bank or institution. The victim is then prompted to enter sensitive information or connected to a live person who uses [[Social engineering (security)|social engineering]] tactics to obtain information.<ref name="vishing" /> Vishing takes advantage of the public's lower awareness and trust in voice telephony compared to email phishing.<ref name="vishingtrust">{{cite book |last1=Wang |first1=Xinyuan |last2=Zhang |first2=Ruishan |last3=Yang |first3=Xiaohui |last4=Jiang |first4=Xuxian |last5=Wijesekera |first5=Duminda |title=Proceedings of the 4th international conference on Security and privacy in communication netowrks |chapter=Voice pharming attack and the trust of VoIP |date=2008 |pages=1–11 |doi=10.1145/1460877.1460908|isbn=9781605582412 |s2cid=7874236 }}</ref>
 
=== SMS phishing (smishing) ===
Be especially concerned about an address containing the "@" symbol, for example <tt><nowiki>http://www.google.com@members.tripod.com/</nowiki></tt>. These addresses will attempt to connect as a user <tt>www.google.com</tt> to the server <tt>members.tripod.com</tt>. This will very likely succeed even if the user does not exist, and the first part of the link may look legitimate.
{{anchor|SMS phishing}}
The same is true for misspelled URLs or subdomains, for example <tt><nowiki>http://www.yourfavbankdomain.com.spamdomain.net</nowiki></tt>.

[[Secunia]] has issued a security advisory on the IDN spoofing issue [http://secunia.com/advisories/14163/], based on the [[IDN homograph attack]]s identified by Eric Johanson [http://www.shmoo.com/idn/homograph.txt]. Users of web browsers that implement IDN are affected. Some websites have noted that [[Internet Explorer]] is safe from this issue. This is misleading, since Internet Explorer has not implemented IDN, and the Verisign IDN plug-in is affected [http://secunia.com/advisories/14209/]. Mozilla developers Darin Fisher and [[Ben Goodger]] point out that [[ICANN]] should prevent the registration of malicious ___domain names. The IDN bug was partially fixed in [[Mozilla]] and [[Mozilla Firefox]] in 24 hours after the bug was announced publicly [http://www.boingboing.net/2005/02/08/mozilla_and_firefox_.html].

Smishing can be just as effective as email phishing, as many smartphones have fast internet connectivity. Smishing messages may also come from unusual phone numbers.<ref>{{cite web|url=https://us.norton.com/internetsecurity-emerging-threats-what-is-smishing.html |title=What is Smishing? |publisher=Symantec Corporation |access-date=18 October 2018}}</ref>
Also, some companies like [[eBay]] and [[PayPal]] always address you by your username in e-mails. If an e-mail addresses you by a generic denomination, for example "''Dear valued eBay member''", it is definitely fake, an attempt at phishing.

{{anchor|Page hijacking}}
'''The following is an example of a phishing e-mail.'''
Page hijacking involves redirecting users to malicious websites or [[exploit kit]]s through the compromise of legitimate web pages, often using [[Cross-site scripting|cross site scripting]]. [[Security hacker|Hacker]]s may insert exploit kits such as [[MPack (software)|MPack]] into compromised websites to exploit legitimate users visiting the server. Page hijacking can also involve the insertion of malicious [[Framing (World Wide Web)|inline frame]]s, allowing exploit kits to load. This tactic is often used in conjunction with [[Watering hole attack|watering hole]] attacks on corporate targets.<ref>{{Cite web |title=What Is a Watering Hole Attack? |url=https://www.fortinet.com/resources/cyberglossary/watering-hole-attack |access-date=2024-07-18 |website=Fortinet |language=en}}</ref>
 
===QR Code phishing (Quishing)===
From: eBay Billing Department <aw-confirm@ebay.com>
{{anchor|Quishing}}
A relatively new trend in online scam activity is "quishing", which means [[QR code|QR Code]] phishing. The term is derived from "QR" (Quick Response) codes and "phishing", as scammers exploit the convenience of QR Codes to trick users into giving up sensitive data, by scanning a code containing an embedded malicious web site link. Unlike traditional phishing, which relies on deceptive emails or websites, quishing uses QR Codes to bypass email filters<ref name="FTquish">{{Cite web |title=Banks and regulators warn of rise in 'quishing' QR code scams |url=https://www.ft.com/content/8aca741e-6448-4511-a54d-64f3a97747b1 |access-date=2024-11-05 |website=Financial Times |language=en|last=Stacey |first=Stephanie |date=2024-10-27 |publisher=The Financial Times Ltd. |quote=Banks and regulators are warning that QR code phishing scams — also known as “quishing” — are slipping through corporate cyber defences and increasingly tricking customers into giving up their financial details.}}</ref><ref name="Wquish1">{{Cite web |title=5 scams you need to know about in 2024 |url=https://www.which.co.uk/news/article/5-scams-you-need-to-know-about-in-2024-ahSpn1K1QAE9 |access-date=2024-11-05 |language=en |last=Lipson |first=Faye |date=2024-02-19 |website=Which? |quote=The criminals have cottoned on to the fact that we tend to assume such codes are genuine and scan them without a second thought.}}</ref> and increase the likelihood that victims will fall for the scam, as people tend to trust QR Codes and may not scrutinize them as carefully as a URL or email link. The bogus codes may be sent by email, social media, or in some cases hard copy stickers are placed over legitimate QR Codes on such things as advertising posters and car park notices.<ref name="BBCquish">{{Cite web |title=Thornaby: Woman targeted in £13k railway station QR code scam |url=https://www.bbc.co.uk/news/uk-england-tees-67335952 |access-date=2024-11-05 |language=en |last=Morris |first=Joanna |date=2023-11-18 |website=BBC News |quote=Fraudsters are thought to have covered a genuine code with one of their own in Thornaby Station's car park.}}</ref><ref name="Wquish2">{{Cite web |title=5 scams you need to know about in 2024 |url=https://www.which.co.uk/news/article/5-scams-you-need-to-know-about-in-2024-ahSpn1K1QAE9 |access-date=2024-11-05 |language=en |last=Lipson |first=Faye |date=2024-02-19 |website=Which? |quote=For example, in recent years phoney QR codes stuck on parking meters by scammers have misdirected drivers to spoofed payment apps, where they end up unwittingly enrolling in costly monthly subscriptions.}}</ref> When victims scan the QR Code with their phone or device, they are redirected to a fake website designed to steal personal information, login credentials, or financial details.<ref name="FTquish" />
 
As QR Codes become more widely used for things like payments, event check-ins, and product information, quishing is emerging as a significant concern for digital security. Users are advised to exercise caution when scanning unfamiliar QR Codes and ensure they are from trusted sources, although the UK's [[National Cyber Security Centre (United Kingdom)|National Cyber Security Centre]] rates the risk as lower than other types of lure.<ref name="NCSCquish">{{Cite web |title=QR Codes - what's the real risk? |url=https://www.ncsc.gov.uk/blog-post/qr-codes-whats-real-risk |access-date=2024-11-05 |language=en |last=C |first=David |date=2024-03-11 |website=The National Cyber Security Centre |quote=...but this type of scam is relatively small compared to other types of cyber fraud.}}</ref>

===Man-in-the-Middle phishing===
Subject: Important Notification
{{anchor|Man-in-the-Middle phishing}}
Traditional phishing attacks are typically limited to capturing user credentials directly inputted into fraudulent websites. However, the advent of [[Man-in-the-middle attack|Man-in-the-Middle]] (MitM) phishing techniques has significantly advanced the sophistication of these attacks, enabling cybercriminals to bypass [[two-factor authentication]] (2FA) mechanisms during a user's active session on a web service. MitM phishing attacks employ intermediary tools that intercept communication between the user and the legitimate service.
 
Evilginx, originally created as an open-source tool for penetration testing and ethical hacking, has been repurposed by cybercriminals for MitM attacks. Evilginx works like a middleman, passing information between the victim and the real website without saving passwords or login codes. This makes it harder for security systems to detect, since they usually look for phishing sites that store stolen data. By grabbing login tokens and session cookies instantly, attackers can break into accounts and use them just like the real user, for as long as the session stays active.

If your problems could not be resolved your account will be suspended for a period of 3-4 days, after this period your account will be terminated.
 
Attackers employ various methods, including phishing emails, social engineering tactics, or distributing malicious links via social media platforms. Once the victim interacts with the counterfeit site, the MitM tool intercepts the authentication process, effectively bypassing 2FA protections.<ref>https://bolster.ai/blog/man-in-the-middle-phishing Understanding Man-in-the-Middle Phishing: A Deep Dive into Evilginx</ref>

===Link manipulation===
Regards,Safeharbor Department eBay, Inc<br>
Phishing attacks often involve creating fake [[Uniform Resource Locator|link]]s that appear to be from a legitimate organization.<ref name="BustSpammers">{{cite web |url=http://www.bustspammers.com/phishing_links.html |title=Get smart on Phishing!

In the following example URL, {{code|http://www.yourbank.example.com/}}, it can appear to the untrained eye as though the URL will take the user to the ''example'' section of the ''yourbank'' website; this URL points to the "''yourbank''" (i.e. phishing subdomain) section of the ''example'' website (fraudster's ___domain name). Another tactic is to make the displayed text for a link appear trustworthy, while the actual link goes to the phisher's site. To check the destination of a link, many email clients and web browsers will show the URL in the status bar when the [[Pointer (user interface)|mouse]] is hovering over it. However, some phishers may be able to bypass this security measure.<ref>{{Cite web |url=http://news.softpedia.com/news/hidden-javascript-redirect-makes-phishing-pages-harder-to-detect-505295.shtml |title=Hidden JavaScript Redirect Makes Phishing Pages Harder to Detect |last=Cimpanu |first=Catalin |date=June 15, 2016 |website=Softpedia News Center |publisher=Softpedia |access-date=May 21, 2017 |quote=Hovering links to see their true ___location may be a useless security tip in the near future if phishers get smart about their mode of operation and follow the example of a crook who recently managed to bypass this browser built-in security feature. |archive-date=March 21, 2021 |archive-url=https://web.archive.org/web/20210321122516/https://news.softpedia.com/news/hidden-javascript-redirect-makes-phishing-pages-harder-to-detect-505295.shtml |url-status=live }}</ref>

==Response by authorities==
In the [[United States]], [[Democrat]] [[Senator]] [[Patrick Leahy]] introduced the ''[[Anti-Phishing Act of 2005]]'' on [[March 1]], [[2005]]. The federal anti-phishing [[bill]] proposes that those criminals who create fake Web sites and [[e-mail spam|spam]] bogus e-mails in order to [[defraud]] consumers could be fined up to $250,000 and have jail terms of up to five years imposed upon them (''[[Information Week]]'', March 2, 2005).
 
===Social engineering===
[[Microsoft]] has joined in on the effort to crack down on ''phishing''. On [[March 31]], [[2005]] Microsoft filed 117 federal lawsuits in the [[U.S. District Court]] for the Western District of [[Washington]]. The lawsuits accuse "[[John Doe]]" defendants of using various different methods to obtain passwords and confidential information about people. They hope to use these lawsuits to uncover some of the largest phishing operators.

Phishing often uses [[Social engineering (security)|social engineering]] techniques to trick users into performing actions such as clicking a link or opening an attachment, or revealing sensitive information.

===Early history===
Early phishing techniques can be traced back to the 1990s, when [[black hat (computer security)|black hat]] hackers and the [[warez]] community used [[AOL]] to steal credit card information and commit other online crimes. The term "phishing" is said to have been coined by Khan C. Smith, a well-known spammer and hacker,<ref>{{cite news |url=http://www.bizjournals.com/atlanta/stories/2002/07/22/story4.html?page=all |title=EarthLink wins $25 million lawsuit against junk e-mailer |access-date=2014-04-11 |archive-date=2019-03-22 |archive-url=https://web.archive.org/web/20190322141415/https://www.bizjournals.com/atlanta/stories/2002/07/22/story4.html?page=all |url-status=live }}</ref> and its first recorded mention was found in the hacking tool [[AOHell]], which was released in 1994. AOHell allowed hackers to impersonate AOL staff and send [[instant message]]s to victims asking them to reveal their passwords.<ref>{{cite news |first=Mike |last=Langberg |title=AOL Acts to Thwart Hackers |date=September 8, 1995 |work=[[San Jose Mercury News]] |url=http://simson.net/clips/1995/95.SJMN.AOL_Hackers.html |access-date=March 14, 2012 |archive-date=April 29, 2016 |archive-url=https://web.archive.org/web/20160429161112/http://simson.net/clips/1995/95.SJMN.AOL_Hackers.html |url-status=live }}</ref><ref>{{cite arXiv |last=Rekouche |first=Koceilah |eprint=1106.4692 |title=Early Phishing |year=2011 |class=cs.CR}}</ref> In response, AOL implemented measures to prevent phishing and eventually shut down the [[warez scene]] on their platform.<ref>{{cite web |title=Phishing |work=Word Spy |url=http://www.wordspy.com/words/phishing.asp |access-date=September 28, 2006 |archive-date=October 15, 2014 |archive-url=https://web.archive.org/web/20141015030058/http://www.wordspy.com/words/phishing.asp |url-status=live }}</ref><ref>{{cite web |title=History of AOL Warez |url=http://www.rajuabju.com/warezirc/historyofaolwarez.htm |access-date=September 28, 2006 |archive-url=https://web.archive.org/web/20110406121144/http://www.rajuabju.com/warezirc/historyofaolwarez.htm |archive-date=April 6, 2011 |url-status=dead |df=mdy }}</ref>

[[Simulated phishing]] campaigns, in which organizations test their employees' training by sending fake phishing emails, are commonly used to assess their effectiveness. One example is a study by the [[United States National Library of Medicine|National Library of Medicine]], in which an organization received 858,200 emails during a 1-month testing period, with 139,400 (16%) being marketing and 18,871 (2%) being identified as potential threats. These campaigns are often used in the healthcare industry, as healthcare data is a valuable target for hackers. These campaigns are just one of the ways that organizations are working to combat phishing.<ref>{{Cite journal|last1=Priestman|first1=Ward|last2=Anstis|first2=Tony|last3=Sebire|first3=Isabel G|last4=Sridharan|first4=Shankar|last5=Sebire|first5=Neil J|date=2019-09-04|title=Phishing in healthcare organisations: threats, mitigation and approaches|journal=BMJ Health & Care Informatics|volume=26|issue=1|pages=e100031|doi=10.1136/bmjhci-2019-100031|issn=2632-1009|pmc=7062337|pmid=31488498}}</ref>
 
Nearly all legitimate e-mail messages from companies to their customers contain an item of information that is not readily available to phishers. Some companies, for example [[PayPal]], always address their customers by their username in emails, so if an email addresses the recipient in a generic fashion ("Dear PayPal customer") it is likely to be an attempt at phishing.<ref>{{cite web|title=Protect Yourself from Fraudulent Emails|url=https://www.paypal.com/us/cgi-bin/webscr?cmd=_vdc-security-spoof-outside|url-status=dead|archive-url=https://web.archive.org/web/20110406114742/https://www.paypal.com/us/cgi-bin/webscr?cmd=_vdc-security-spoof-outside|archive-date=April 6, 2011|access-date=July 7, 2006|work=PayPal}}</ref> Furthermore, PayPal offers various methods to determine spoof emails and advises users to forward suspicious emails to their spoof@PayPal.com ___domain to investigate and warn other customers.

===Technical approaches===
A wide range of technical approaches are available to prevent phishing attacks reaching users or to prevent them from successfully capturing sensitive information.
 
====Filtering out phishing mail====
Specialized [[Email filtering|spam filters]] can reduce the number of phishing emails that reach their addressees' inboxes. These filters use a number of techniques including [[machine learning]]<ref>{{cite journal |journal=Applied Soft Computing |title=Obtaining the Threat Model for E-mail Phishing |first1=Cleber K.|last1=Olivo |first2=Altair O.|last2=Santin |first3=Luiz S.|last3=Oliveira |date=July 2011 |doi=10.1016/j.asoc.2011.06.016 |volume=13 |issue=12 |pages=4841–4848}}</ref> and [[natural language processing]] approaches to classify phishing emails,<ref>{{cite web |work=NYS Cyber Security Symposium |title=Phishing E-mail Detection Based on Structural Properties |author1=Madhusudhanan Chandrasekaran |author2=Krishnan Narayanan |author3=Shambhu Upadhyaya |date=March 2006 |url=http://www.albany.edu/iasymposium/2006/chandrasekaran.pdf |archive-url=https://web.archive.org/web/20080216101637/http://www.albany.edu/iasymposium/2006/chandrasekaran.pdf |archive-date=February 16, 2008 }}</ref><ref>{{cite web |work=Carnegie Mellon University Technical Report CMU-ISRI-06-112 |title=Learning to Detect Phishing Emails |author1=Ian Fette |author2=Norman Sadeh |author3=Anthony Tomasic |date=June 2006 |url=http://reports-archive.adm.cs.cmu.edu/anon/isri2006/CMU-ISRI-06-112.pdf |access-date=2006-11-30 |archive-date=2018-06-19 |archive-url=https://web.archive.org/web/20180619230609/http://reports-archive.adm.cs.cmu.edu/anon/isri2006/CMU-ISRI-06-112.pdf |url-status=live }}</ref> and reject email with forged addresses.<ref name=DMARC>{{cite web |title=Landing another blow against email phishing (Google Online Security Blog) |url=http://googleonlinesecurity.blogspot.jp/2012/01/landing-another-blow-against-email.html |access-date=June 21, 2012 |archive-date=June 6, 2012 |archive-url=https://web.archive.org/web/20120606063119/http://googleonlinesecurity.blogspot.jp/2012/01/landing-another-blow-against-email.html |url-status=live }}</ref>
 
====Browsers alerting users to fraudulent websites====
[[File:Firefox 2.0.0.1 Phising Alert.png|thumb|Screenshot of Firefox 2.0.0.1 Phishing suspicious site warning]]
Another popular approach to fighting phishing is to maintain a list of known phishing sites and to check websites against the list. One such service is the [[Google Safe Browsing|Safe Browsing]] service.<ref>{{cite web|url=https://www.google.com/safebrowsing/static/faq.html|title=Google Safe Browsing|access-date=2017-11-30|archive-date=2017-09-01|archive-url=https://web.archive.org/web/20170901031928/http://www.google.com/safebrowsing/static/faq.html|url-status=live}}</ref> Web browsers such as [[Google Chrome]], [[Internet Explorer]] 7, [[Mozilla Firefox]] 2.0, [[Safari (web browser)|Safari]] 3.2, and [[Opera (web browser)|Opera]] all contain this type of anti-phishing measure.<ref name="Google">{{cite web|url=http://googleonlinesecurity.blogspot.jp/2012/06/safe-browsing-protecting-web-users-for.html|title=Safe Browsing (Google Online Security Blog)|access-date=June 21, 2012|archive-date=March 5, 2016|archive-url=https://web.archive.org/web/20160305144600/https://googleonlinesecurity.blogspot.jp/2012/06/safe-browsing-protecting-web-users-for.html|url-status=live}}</ref><ref>{{cite web|author=Franco, Rob |title=Better Website Identification and Extended Validation Certificates in IE7 and Other Browsers |work=IEBlog |date=21 November 2005 |url=https://docs.microsoft.com/en-us/archive/blogs/ie/better-website-identification-and-extended-validation-certificates-in-ie7-and-other-browsers |access-date=Feb 10, 2020 |archive-url=https://web.archive.org/web/20100125235945/http://blogs.msdn.com/ie/archive/2005/11/21/495507.aspx |archive-date=January 25, 2010 |url-status=live |df=mdy }}</ref><ref>{{cite web|title=Bon Echo Anti-Phishing |work=Mozilla |url=https://www.mozilla.org/projects/bonecho/anti-phishing/ |access-date=June 2, 2006 |archive-url=https://web.archive.org/web/20060924074349/http://www.mozilla.org/projects/bonecho/anti-phishing/ |archive-date=September 24, 2006 |url-status=live |df=mdy }}</ref><ref>{{cite web|title=Safari 3.2 finally gains phishing protection |date=November 13, 2008 |access-date=November 15, 2008 |work=Ars Technica |url=https://arstechnica.com/journals/apple.ars/2008/11/13/safari-3-2-finally-gains-phishing-protection |archive-url=https://web.archive.org/web/20090209070213/http://arstechnica.com/journals/apple.ars/2008/11/13/safari-3-2-finally-gains-phishing-protection |archive-date=February 9, 2009 |url-status=live |df=mdy }}</ref><ref>{{cite news |url=http://www.3sharp.com/projects/antiphish/index.htm |archive-url=https://archive.today/20080114211315/http://www.3sharp.com/projects/antiphish/index.htm |url-status=dead |archive-date=January 14, 2008 |title=Gone Phishing: Evaluating Anti-Phishing Tools for Windows |date=September 27, 2006 |access-date=October 20, 2006 |publisher=3Sharp}}</ref> [[Firefox 2]] used [[Google]] anti-phishing software.

An approach introduced in mid-2006 involves switching to a special DNS service that filters out known phishing domains.<ref>

To mitigate the problem of phishing sites impersonating a victim site by embedding its images (such as [[logo]]s), several site owners have altered the images to send a message to the visitor that a site may be fraudulent. The image may be moved to a new filename and the original permanently replaced, or a server can detect that the image was not requested as part of normal browsing, and instead send a warning image.<ref>{{cite news |last=Krebs |first=Brian |url=http://blog.washingtonpost.com/securityfix/2006/08/using_images_to_fight_phishing.html |title=Using Images to Fight Phishing |date=August 31, 2006 |publisher=Security Fix |url-status=dead |archive-url=https://web.archive.org/web/20061116184842/http://blog.washingtonpost.com/securityfix/2006/08/using_images_to_fight_phishing.html |archive-date=November 16, 2006 }}</ref><ref>{{cite news |last=Seltzer |first=Larry |url=http://www.eweek.com/article2/0,1759,1630161,00.asp |title=Spotting Phish and Phighting Back |date=August 2, 2004 |publisher=eWeek |access-date=December 14, 2006 |archive-date=July 5, 2019 |archive-url=http://webarchive.loc.gov/all/20190705083348/https://www.eweek.com/mobile/hp%2Dtouchpad%2Dneeds%2D6%2Dto%2D8%2Dweeks%2Dfor%2Dadditional%2Dshipments |url-status=live }}</ref>

Users of the bank's online services were instructed to enter a password only when they saw the image they selected. The bank has since discontinued the use of SiteKey. Several studies suggest that few users refrain from entering their passwords when images are absent.<ref>{{cite news |last=Stone |first=Brad |title=Study Finds Web Antifraud Measure Ineffective |url=https://www.nytimes.com/2007/02/05/technology/05secure.html?ex=1328331600&en=295ec5d0994b0755&ei=5090&partner=rssuserland&emc=rss |work=The New York Times |access-date=February 5, 2007 |date=February 5, 2007 |archive-date=June 11, 2019 |archive-url=https://web.archive.org/web/20190611001932/https://www.nytimes.com/2007/02/05/technology/05secure.html?ex=1328331600&en=295ec5d0994b0755&ei=5090&partner=rssuserland&emc=rss |url-status=live }}</ref><ref>

Unlike the website-based image schemes, however, the image itself is shared only between the user and the browser, and not between the user and the website. The scheme also relies on a [[mutual authentication]] protocol, which makes it less vulnerable to attacks that affect user-only authentication schemes.
 
Still another technique relies on a dynamic grid of images that is different for each login attempt. The user must identify the pictures that fit their pre-chosen categories (such as dogs, cars and flowers). Only after they have correctly identified the pictures that fit their categories are they allowed to enter their alphanumeric password to complete the login. Unlike the static images used on the Bank of America website, a dynamic image-based authentication method creates a one-time passcode for the login, requires active participation from the user, and is very difficult for a phishing website to correctly replicate because it would need to display a different grid of randomly generated images that includes the user's secret categories.<ref>{{cite web |url=http://www.confidenttechnologies.com/products/anti-phishing |title=Dynamic, Mutual Authentication Technology for Anti-Phishing |publisher=Confidenttechnologies.com |access-date=September 9, 2012 }}</ref>

====Multi-factor authentication====
Organizations can implement two factor or [[multi-factor authentication]] (MFA), which requires a user to use at least 2 factors when logging in. (For example, a user must both present a [[smart card]] and a [[password]]). This mitigates some risk, in the event of a successful phishing attack, the stolen password on its own cannot be reused to further breach the protected system. However, there are several attack methods which can defeat many of the typical systems.<ref>{{cite news |last1=Kan |first1=Michael |title=Google: Phishing Attacks That Can Beat Two-Factor Are on the Rise |url=https://www.pcmag.com/news/367026/google-phishing-attacks-that-can-beat-two-factor-are-on-the |access-date=9 September 2019 |work=PC Magazine |date=7 March 2019 |archive-date=8 March 2019 |archive-url=https://web.archive.org/web/20190308035745/https://www.pcmag.com/news/367026/google-phishing-attacks-that-can-beat-two-factor-are-on-the |url-status=live }}</ref> MFA schemes such as [[WebAuthn]] address this issue by design.
