Maggie: New Backdoor Targeting Microsoft SQL Servers

Read Time:1 Minute, 20 Second

FortiGuard Labs is aware of reports that a new backdoor called “Maggie” targets Microsoft SQL servers. Maggie connects to Command and Control (C2) servers for remote commands and supports a variety of commands such as downloading, executing,and deleting files and propagates to other SQL servers through bruteforcing as well as unknown exploit commands. Based on external reports, most infected Microsoft SQL servers are in Asia.Why is this Significant?This is significant because Maggie is a new backdoor malware that has reportedly infected Microsoft SQL servers around the globe, with heavy concentration in Asia. The backdoor allows a remote attacker to control infected SQL servers. Maggie also supports commands to propagate to other SQL servers through bruteforcing.What is Maggie malware?Maggie is a backdoor malware that targets Microsoft SQL servers. The backdoor allows a remote attacker to control infected servers and supports commands such as downloading, executing and deleting files, turning on and off remote desktop services (TermService) as well as propagating to other SQL servers through bruteforcing. Reportedly, Maggie is also capable of accepting unidentified exploit related commands.The attacker disguised Maggie as “sqlmaggieAntiVirus_64.dll” signed with a digital certificate belonging to a company in South Korea. The file is an Extended Stored Procedure (ESP) DLL that the malware abuses for backdoor activities.At the time of this writing, an initial infection vector has not been identified.What is the Status of Protection?FortiGuard Labs provides the following AV signatures for Maggie malware and relevant files:W64/JuicyPotato.AI!trRiskware/Inject.HEUR!tr.pwsAll network IOCs are blocked by the WebFiltering client.
