Frequently Asked Questions
What is the Razy malware family?
Razy is malware focused on cryptocurrency theft. As described by Kaspersky, it uses a malicious browser extension to steal cryptocurrency from infected users.
How does Razy steal cryptocurrency?
Razy operates through a malicious browser extension, which lets it tamper with cryptocurrency-related web content and the browser environment in order to capture or redirect funds.
Why does Razy target browsers?
Cryptocurrency transactions are frequently performed through web interfaces, so by embedding itself as a browser extension Razy gains a position to observe and manipulate those activities.
How do I remove the Razy Infostealer from Windows?

Symptoms of Razy can include unexpected system slowness, unauthorized outbound network traffic to unknown IP addresses, disabled security software, and suspicious background processes running from AppData or Temp directories.
