The number of users attacked by malware out to steal premium access login data to popular adult websites more than doubled in a year, rising from around 50,000 users in 2017 to 110,000 users in 2018. In all, more than 850,000 attacks were detected. This growth was accompanied by more offers of stolen credential for sale on dark web markets and an increase in the number of malware families launching attacks. These and other findings are unveiled in Kaspersky Lab’s report on threats to users of adult websites in 2018. 

While porn is usually considered a good decoy to attract victims to a malicious website or involve them in a fraud scheme, the adult content itself wasn’t previously considered worth hunting for. However, the new report shows that porn, namely premium accounts to porn websites, which include access to exclusive content, are gaining more and more attention from fraudsters. 

To steal the credentials to a premium account on an adult-content website, cybercriminals distribute malware through botnets: chains of ‘bots’ or devices infected with malware capable of downloading additional malware depending on the goals of the botnet master. In the case of credential stealing threats, these botnets are usually formed by versions of known Banking Trojans that were repurposed to attack users of adult websites. They intercept their victims’ data traffic and redirect them to fake web pages that mirror the authentic adult site the user is attempting to visit, capturing the credentials when the user tries to log in to their premium account. Such an approach is increasingly popular among cybercriminals and usually leads to victims’ personal information being exposed and used by criminals. In addition, a victim can sometimes find themselves locked out of accounts for which they could be paying a subscription of 150$ USD per year. 

According to Kaspersky Lab’s researchers, the rising number of users facing such malware is matched by its intensified productivity. The number of porn-related attacks by these programs increased almost three-fold: from 307,868 attacks in 2017 to 850,000 in 2018. Such an increase could be linked to a rise in the number of malware families distributed by botnets to hunt for porn login credentials.  In 2018, Kaspersky Lab experts uncovered 22 variations of bots distributing five families of Banking Trojans for such attacks: Betabot, Gozi, and Panda – also known to target users of popular e-commerce brands – along with Jimy, and Ramnit. The last two, like Gozi are new to porn login attacks. In 2017, 27 variations of bots distributed just three malware families, Betabot, Neverquest and Panda. 

The increase in attacks was accompanied by a rise in the number of offers related to stolen credentials on dark web markets: the research shows that in 2018 the number of unique offers for porn website premium access credentials doubled to reach more than 10,000, compared to around 5,000 in 2017. The price, however, remained the same – around 5-10$ for each account. 

While premium access credentials to porn websites might not seem the most obvious thing to steal,  our research suggests that it’s a profitable line of illegal business and that cybercriminals are increasingly looking for opportunities to target victims in this mannerMalware can remain unnoticed and undetected on a victim’s device for a significant timeThis means that their data is potentially at a greater risk as hackers can essentially continue to spy on their victims’ private actionsand use stolen credentials for their own benefit,” said David Emm, Principal Security Researcher at Kaspersky Lab. 

Apart from this notorious trend, Kaspersky Lab researchers have also seen the number of attacks coming from phishing pages that pretending to be one of the major porn websites with free content grow more than 10 times in Q4 2018 comparing to Q4 2017. 

Overall, the number of attempts to visit phishing webpages pretending to be one of the popular adult-content resources was 38,305. Leading the list of accessed phishing pages were those that were disguised as a Pornhub page. There were 37,144 attempts to visit the phishing version of the website, while there were only 1,161 attempts to visit Youporn, Xhamster, and Xvideos in total. 

To protect yourself from a phishing attack pretending to be 

  • Do not click on malicious phishing links in your e-mails: we never send unsolicited emails or text messages asking for confidential information, such as a password;
  • When in doubt, go to instead of clicking a link, such as in an email;
  • Always check that the domain name is;
  • Always check that your connection is using HTTPS and that the certificate is valid
  • Report any suspicious activity to

Pornhub commented on the issue with the following statement: 

Although the number of phishing may seem high, it’s important to note that in relation to the amount of site visits (33.5 billion visits in 2018), the percentage of phishing attempts is very small (less than .0001%). This low percentage rate can be attributed to the fact that Pornhub actively monitors and removes phishing websites and offers two-factor authentication when logging into PornHub accounts”. 

Other findings of the report include: 

  • Searching for pornography online has become safer:in 2018, 650,000 users faced attacks launched from online resources – 36% less than in 2017 when more than a million of these attacks were detected. 
  • Cybercriminals are actively using popular porn-tags (such asPornstar or HD-porn) to promote malware in search results. Overall, 87,227 unique users faced such malware in 2018. 
  • Porn-themed malware samples are found in great variety, with 642 families and 57 types of PC threats.
  • 89%of infected files disguised as pornography on Android devices turned out to be AdWare. 

To reduce the risk of infection, users are advised to: 

  • Pay extra attention to the website’s authenticity. Do not visit websites until you are sure that they are legitimate and start with ‘https’, especially when any credentials are asked for. 
  • Have a separate bank card and account with a limited amount of money specifically for premium account activation and extension of the subscription. This will help to avoid financial losses if your bank details are stolen. 
  • Use reliable security solutions for comprehensive protection from a wide range of threats, including Banking Trojans, such as Kaspersky Security Cloud and Kaspersky Internet Security. 
  • Never use the same password for several websites or services. To create strong, hack-proof passwords and remove the struggle of remembering them, use a specific password manager application, such as Kaspersky Password Manager. 
  • Businesses can also restrict access to web sites that do not comply with corporate policy, such as porn sites, by a using dedicated endpoint solution such as Kaspersky Endpoint Security for Business. In addition to anti-spam and anti-phishing, it must include application and web controls, and web threat protection that can detect and block access to malicious or phishing web addresses.
