Stealer malware has become one of the most pervasive cybersecurity threats today. This type of malware is specifically designed to harvest sensitive data from infected devices, making it a lucrative tool for cybercriminals. Whether it's your login credentials, banking information, or personal files, stealer malware can cause immense damage once it infiltrates your system.
How Stealer Malware Works
Stealer malware operates by silently infiltrating your system and scanning for valuable information to exfiltrate. This process typically follows a few key steps:
The Infection Lifecycle
- Infection Vector: Enters via phishing emails, malicious downloads, or compromised websites.
-
Data Harvesting: Scans for:
- Credentials stored in browsers
- Cryptocurrency wallets
- Files with personal or financial data
- Saved session cookies
- System info (Hardware IDs, IP addresses)
- Exfiltration: Sends collected data to a remote server (C2) controlled by the attacker.
- Persistence: Establishes mechanisms to remain undetected and survive system reboots.
