Researchers have noticed a brand new menace 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.

Risk 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 up to now noticed GambleForce assaults on at the very least two dozen organizations throughout Australia, Indonesia, Philippines, India, and South Korea. “In some cases, the attackers stopped after performing reconnaissance,” Group-IB senior menace 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 menace actor executes unauthorized actions — like retrieve, modify, or delete knowledge — in a Internet 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 Internet utility vulnerabilities and accounted for 33% of all found Internet 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typically overlook how essential enter safety and knowledge validation are, which ends up in weak coding practices, outdated software program, and improper database settings,” Rostovcev stated.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 menace actor’s reliance on publicly out there penetration testing software program to hold out these assaults. When Group-IB’s analysts lately analyzed instruments hosted on the menace 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 menace actor seems to have particularly chosen for executing SQL injection assaults.

Publicly Accessible Pen-Testing Instruments

The listing of instruments that Group-IB found on the C2 server included dirsearch, a software for locating hidden recordsdata and directories on a system; redis-rogue-getshell, a software that allows distant code execution on Redis installations; and sqlmap, for locating and exploiting SQL vulnerabilities in an setting. 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 isn’t proof of the menace group’s origin nation, the safety vendor stated. One other trace in regards to the menace group’s potential residence 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 methods.

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

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