Malicious software known as Stealerium covertly snaps webcam pictures for extortion purposes.
In the digital world, a new threat has emerged, with an increased number of Stealerium-based attacks reported since May 2025. This malicious software, written in the C# programming language and freely available on GitHub, is a cause for concern for many internet users.
Stealerium, as the name suggests, is designed to steal sensitive data from victims' devices. It secretly takes screenshots, webcam recordings, and records keyboard inputs (keylogging) without the user's knowledge. The malware can also detect when a user visits pornographic websites and extract banking and cryptocurrency data, as well as passwords.
The anonymous author of the malware claims it was made available online for "educational purposes." However, Stealerium can bypass various protective mechanisms of a computer, making it a potent threat. It is typically distributed via email attachments, often disguised as legitimate files.
Particular caution should be exercised with attachments having the file extensions .js, .vbs, ISO, and IMG. If in doubt, it's best not to open such emails. Users should also be sensitized to treat suspicious emails containing payment demands, court summons, and donation requests with caution.
To protect against Stealerium, executable files should ideally be blocked. If you suspect you've been targeted, it's essential to run a thorough system scan and change all passwords immediately.
Remember, the internet can be a dangerous place. Always stay vigilant and cautious when navigating it. If you encounter any suspicious activity, report it to your internet service provider or cybersecurity authorities. Stay safe, and let's keep the digital world a safer place for everyone.
