Packers are becoming an increasingly important tool for cybercriminals to use in the commission of illegal acts. On hacker forums, the packer is sometimes referred to as “Crypter” and “FUD.” Its primary function is to make it more difficult for antivirus systems to identify malicious code. Malicious actors are able to disseminate their malware more quickly and with fewer consequences when they use a packer. It doesn’t matter what the payload is, which is one of the primary qualities of a commercial Packer-as-a-Service, which implies that it may be used to pack a variety of different harmful samples. This opens up a lot of opportunities for cybercriminals. Another key quality of the packer is that it is transformational. Because the packer’s wrapper is changed on a frequent basis, it is able to avoid detection by devices designed to enhance security.
According to Checkpoint, TrickGate is an excellent illustration of a robust and resilient packer-as-a-service. It has been able to go under the radar of cyber security researchers for a number of years and is consistently becoming better in a variety of different ways.
Although a lot of very good study was done on the packer itself, TrickGate is a master of disguises and has been given a number of different titles due to the fact that it has so many different characteristics. A number of names have been given to it, including “TrickGate,” “Emotet’s packer,” “new loader,” “Loncom,” and “NSIS-based crypter.”
At the end of 2016, they made our first observation of TrickGate. During that time, it was used to spread the Cerber malware. Since that time, they have been doing ongoing research on TrickGate and have discovered that it is used to propagate many forms of malicious software tools, including ransomware, RATs, information thieves, bankers, and miners. It has come to their attention that a significant number of APT organizations and threat actors often employ TrickGate to wrap their malicious code in order to evade detection by security solutions. Some of the most well-known and top-distribution malware families have been wrapped by TrickGate,
including Cerber, Trickbot, Maze, Emotet, REvil, CoinMiner, Cobalt Strike, DarkVNC, BuerLoader, HawkEye, NetWire, AZORult, Formbook, Remcos, Lokibot, AgentTesla, and many more. TrickGate has also been involved in the wrapping of many other malware.
