GoBruteforcer Botnet Targets Crypto Projects via Weak Credentials — tl;dr: The GoBruteforcer botnet is exploiting weak credentials in cryptocurrency and blockchain project databases, enabling brute-force attacks on services like FTP and MySQL. This surge in attacks is attributed to the widespread use of AI-generated server setups with common usernames and inadequate security measures. Cybersecurity experts recommend organizations to strengthen password policies, implement two-factor authentication, and regularly audit their server configurations to mitigate the risk of such attacks. Awareness and proactive measures are essential to protect sensitive data from being compromised.
