Privnote.com, launched in 2008, revolutionized secure messaging with its encryption technology. It allows users to send messages with a unique link, ensuring privacy as the content self-destructs after reading. However, its popularity among cryptocurrency enthusiasts also drew the attention of malicious actors who engaged in phishing activities. 

Phishers exploit Privnote's model by creating clones, such as privnote[.]co, that mimic its functionality. These clones surreptitiously replace cryptocurrency addresses when users create notes containing crypto wallets. Thus, unsuspecting users fall victim to sending funds to the phisher's address instead of the intended recipient. 

GitHub user, fory66399, lodged a complaint last month against MetaMask, a cryptocurrency wallet, alleging wrongful flagging of privnote[.]co as malicious. Threatening legal action, fory66399 demanded evidence and compensation. However, MetaMask's lead product manager, Taylor Monahan, swiftly debunked these claims by providing screenshots showing the fraudulent activities of privnote[.]co. 

According to DomainTools.com, the domain privatenote[.]io has changed hands between two individuals: Andrey Sokol from Moscow and Alexandr Ermakov from Kiev, over two years. While these names may not be the real identities of the scammers, they provide clues to other sites targeting Privnote since 2020. 

Furthermore, Alexandr Ermakov is linked to several other domains, including pirvnota[.]com, privatemessage[.]net, privatenote[.]io, and tornote[.]io, as per DomainTools. This suggests a potential network of fraudulent activities associated with Privnote, emphasizing the need for caution in identifying phishing attempts. 

Domain Registrations: The domain pirvnota[.]com saw a change in registration details from Andrey Sokol to "BPW" and "Tambov district" as the registrant's state/province. This led to the discovery of pirwnote[.]com, along with other suspicious domains like privnode[.]com, privnate[.]com, and prevnóte[.]com, all linking to the same internet address. Interestingly, pirwnote[.]com is now selling security cameras from a Hong Kong-based internet address. 

Deceptive Legitimacy: Tornote[.]io appears to have undergone efforts to establish credibility. A Medium account has published numerous blog posts endorsing Tornote as a secure messaging service. However, testing reveals its malicious intent, as it also alters cryptocurrency addresses in messages. 

Search Engine Manipulation: Phishing sites manipulate search engine results to appear prominently for terms like "privnote." Currently, a Google search for "privnote" lists tornote[.]io as the fifth result. These sites rotate cryptocurrency addresses every five days to evade detection. 

According to the Privnote website, it is a web-based service focused on privacy, allowing users to create encrypted notes shared via unique one-time-use HTTPS links. Notes and their contents are processed securely in users' browsers, with no readable data stored on Privnote's servers. 

IP addresses are processed solely for communication and promptly deleted thereafter. Personal data within notes remains encrypted and inaccessible to Privnote. The service uses cookies for functional and non-functional purposes, respecting user privacy preferences. Privnote does not target children under 16 and commits to regularly updating its Privacy Policy.
