Security News > 2022 > October > Hundreds of Microsoft SQL servers backdoored with new malware

Security researchers have found a new piece of malware targeting Microsoft SQL servers.
Named Maggie, the backdoor has already infected hundreds of machines all over the world.
Maggie is controlled through SQL queries that instruct it to run commands and interact with files.
Its capabilities extend to brute-forcing administrator logins to other Microsoft SQL servers and doubling as a bridge head into the server's network environment.
The malware offers simple TCP redirection functionality, which allows remote attackers to connect to any IP address the infected MS-SQL server can reach.
At this time some details remain unknown, like the post-infection use of Maggie, how the malware is planted in the servers in the first place, and who is behind these attacks.
