We are talking about stealer malware, a brazen form of cyberattack that gains access to our systems undetected and steals sensitive data.

Imagine unsuspectingly downloading software from untrustworthy sources or using pirated programs. Without you realizing it, the stealer malware sneaks into your systems and starts its secret mission.

This stolen data is then forwarded to those behind it without your knowledge.

The range of what can be stolen is frightening. Everything from sensitive session tokens and cookie information to login credentials for email or bank accounts are targeted by this insidious malware.
