Evil Has New Cyber Weapons

New data released by Prodaft Threat Intelligence (PTI) explains how the Evil Corp ransomware gang, also known as TA505 and UNC2165, has expanded its cyber weapon arsenal to include TeslaGun.

The cyber attack panel referred to as TeslaGun has been leveraged by the group to help conduct phishing campaigns and ServHelper backdoor campaigns. The campaigns have targeted more than 8,000 different organisations and individuals, according to PTI.

The group has also been expanding the ServHelper backdoor malware that has been around since at least 2019. Evil began to use a latest version of the tool in 2021, according to security researchers at Cisco Talos. The majority of the malicious hacking group’s targets to date have been in the US. 

Most recently, the backdoor has been identified in attacks that drop hidden cryptominers on systems. "The group does exhibit some weaknesses, however. While TA505 can maintain hidden connections on victims’ devices for months, its members are often unusually noisy," the report said. "After installing ServHelper, TA505 threat actors may manually connect to victim devices through RDP tunneling. Security technologies capable of detecting these tunnels may prove vital for catching and mitigating TA505's backdoor attacks."

The Russian-linked Evil Corp has been one of the most prolific groups of the last five years. According to the US government, the group is behind the financial Trojan Dridex and has associations with campaigns using ransomware variants like WastedLocker.

The US Treasury Department's Office of Foreign Assets Control sanctioned Evil Corp in 2019, citing the group's extensive development and use and control of the Dridex malware . Since the sanctions were announced, Evil Corp-affiliated actors have changed their name a number of times.

 According to the US Treasury “Evil Corp has used the Dridex malware to infect computers and harvest login credentials from hundreds of banks and financial institutions in over 40 countries, causing more than $100 million in theft...  This malicious software has caused millions of dollars of damage to US and international financial institutions and their customers.”
