Overview of BTC Stealer 2025
This software is a type of malware specifically engineered to locate and exfiltrate cryptocurrency-related data from infected systems. It primarily targets wallet files, browser-stored credentials, and clipboard contents (to hijack transactions). The malware is typically distributed through phishing campaigns, fake cryptocurrency apps, or bundled with pirated software. Once executed, it scans the system for valuable data and sends it to a remote server controlled by the attacker. Cybercriminals often use this tool in combination with other malware, such as keyloggers or infostealers, to maximize their theft potential.
