Group-IB, a global threat hunting and intelligence company headquartered in Singapore, has detected a successful attack by a ransomware gang, codenamed OldGremlin. The Russian-speaking threat actors are relatively new to the Big Game Hunting. Since March, the attackers have been trying to conduct multistage attacks on large corporate networks of medical labs, banks, manufacturers, and software developers in Russia. The operators use a suite of custom tools with the ultimate goal of encrypting files in the infected system and holding it for a ransom of about $50,000.
