Hackers infect MySQL servers with malware for DDoS attacks

Hackers are exploiting SQL injection flaws to infect MySQL database servers with a malware program that’s used to launch distributed denial-of-service (DDoS) attacks.

Security researchers from Symantec found MySQL servers in different countries infected with a malware program dubbed Chikdos that has variants for both Windows and Linux.

This Trojan is not new and was first documented in 2013 by incident responders from the Polish Computer Emergency Response Team (CERT.PL). At that time the malware was being installed on servers after using brute-force dictionary attacks to guess SSH (Secure Shell) login credentials.

However, the new attacks observed by Symantec abuse the user-defined function (UDF) capability of the MySQL database engine. UDF allows developers to extend the functionality of MySQL with compiled code.
