New ‘GambleForce’ Menace Actor Behind String of SQL Injection Assaults

Researchers have noticed a brand new risk actor focusing on organizations within the Asia-Pacific area with SQL injection assaults utilizing nothing greater than publicly out there, open supply penetration-testing instruments.

Menace hunters at Group-IB first noticed the brand new group in September, focusing on playing firms within the area and named it “GambleForce.” Within the three months since, the group has focused organizations in a number of different sectors, together with authorities, retail, journey, and job web sites.

The GambleForce Marketing campaign

In a report this week, Group-IB stated it has thus far noticed GambleForce assaults on a minimum of two dozen organizations throughout Australia, Indonesia, Philippines, India, and South Korea. “In some cases, the attackers stopped after performing reconnaissance,” Group-IB senior risk analyst Nikita Rostovcev wrote. “In different instances, they efficiently extracted consumer databases containing logins and hashed passwords, together with lists of tables from accessible databases.”

SQL injection assaults are exploits the place a risk actor executes unauthorized actions — like retrieve, modify, or delete information — in a Net utility database by profiting from vulnerabilities that enable malicious statements to be inserted into enter fields and parameters that the database processes. SQL injection vulnerabilities stay one the commonest Net utility vulnerabilities and accounted for 33% of all found Net utility flaws in 2022.

“SQL assaults persist as a result of they’re easy by nature,” Group-IB stated. “Corporations typically overlook how essential enter safety and information validation are, which ends up in weak coding practices, outdated software program, and improper database settings,” Rostovcev stated.

What makes GambleForce’s marketing campaign noteworthy in opposition to this background is the risk actor’s reliance on publicly out there penetration testing software program to hold out these assaults. When Group-IB’s analysts just lately analyzed instruments hosted on the risk actor’s command-and-control (C2) server, they could not discover a single customized software. As an alternative, all of the assault weapons on the server have been publicly out there software program utilities that the risk actor seems to have particularly chosen for executing SQL injection assaults.

Publicly Out there Pen-Testing Instruments

The listing of instruments that Group-IB found on the C2 server included dirsearch, a software for locating hidden information and directories on a system; redis-rogue-getshell, a software that permits distant code execution on Redis installations; and sqlmap, for locating and exploiting SQL vulnerabilities in an atmosphere. Group-IB additionally found GambleForce utilizing the favored open supply pen-testing software Cobalt Strike for post-compromise operations.

The Cobalt Strike model found on the C2 server used Chinese language instructions. However that alone shouldn’t be proof of the risk group’s origin nation, the safety vendor stated. One other trace in regards to the risk group’s potential dwelling base was the C2 server loading a file from a supply that hosted a Chinese language-language framework for creating and managing reverse shells on compromised techniques.

In line with Group-IB, out there telemetry means that GambleForce actors are usually not on the lookout for any particular information when attacking and extracting information from compromised Net utility databases. As an alternative, the risk actor has been making an attempt to exfiltrate no matter information it will possibly lay its fingers on, together with plaintext and hashed consumer credentials. Nonetheless, It is unclear how precisely the risk actor may be utilizing the exfiltrated information, the safety vendor stated.

Group-IB researchers took down the risk actor’s C2 server quickly after discovering it. “Nonetheless, we imagine that GambleForce is almost definitely to regroup and rebuild their infrastructure earlier than lengthy and launch new assaults,” Rostovcev stated.
