Cyber intelligence company, CdlouSEK, has developed a report to analyze hacking activities on YouTube, and found that there is a 200% to 300% monthly increase in videos with descriptions containing infostealers.
Infostealers are malware designed to steal sensitive information from a user's computer or device. They typically work by infecting a device and silently monitoring user activity, in search for sensitive data such as login credentials, credit card numbers or personal information.

Hackers post video tutorials explaining how to download and install software such as Adobe Photoshop, Premiere Pro, Autodesk 3ds Max, AutoCAD and others. In addition, content generated by AI platforms such as Synthesia and D-ID, which produce images of humans, was identified.
According to CloudSEK, the software is used for educational, recruitment and promotion purposes. However, cybercriminals take advantage of all this technology to steal user information and data.
Infostealers can spread in a variety of ways, including via phishing emails, malicious websites, or as a payload attached to other types of malware. Once installed, they can be difficult to detect and remove, often requiring specialized tools or knowledge.
Some common types of infostealers include keyloggers, which capture all keystrokes in a device, and password stealers, specifically designed to capture login credentials for various online services.
Information captured by infostealers
- Browser data: passwords, cookies, extension data, autofills, credit card details, among others;
- Cryptographic wallet data and passwords;
- Data and passwords of telegram;
- Files: .txt, documents, Excel spreadsheets, PowerPoint presentations, etc. They manage to hijack this information using a File Grabber;
- System information: IP address, malware path, time zone, location, system specs, etc.
How to protect against infostealers
- Use strong passwords;
- Keep your software and operating system up to date with the latest security patches;
- Avoid clicking on suspicious links or downloading attachments from unknown sources;
- Using reputable antivirus and antimalware software can help detect and remove information thieves before they can do damage.
