Otherwise, if the value of the first byte in the config file is 0x00, it means that the config file is encrypted with a key derived from the SOFTWARE\Microsoft\Cryptography\MachineGuid value.ġ) The CRC32 checksum of the input (.bmp file) is computed.Ģ) The checksum is converted to a hexadecimal string (eight characters), and all characters are converted to uppercase.Ĥ) The hexadecimal string representation of the hash (32 characters) is used as the RC4 password to decrypt the config file.Īfter decryption, the configuration file contains the URL address of the command-and-control (C&C) server. If its value is 0x01, it means that the malware runs for the first time and the config file is encrypted with a key derived from the bitmap file. Initially, the first byte of the config file is checked. The DLL is responsible for decrypting the config file. Figures 1 to 4 are some examples of these fake websites. The dropper poses as a fake cryptocurrency wallet, miner, or surfing plug-in. The malware dropper of SpyAgent is distributed via fake cryptocurrency-related websites that are usually in the Russian language. The malware sets the access password to a fixed one, so that merely knowing the RAT’s ID is enough for the attacker to successfully connect to the infected machine. The malicious DLL then begins reporting the RAT’s ID, which the malware operator needs to connect to and control the infected machine. This results in the RAT windows being hidden from a user. This DLL hooks and patches various API functions called by the RAT. This involves the exploit of a DLL sideloading vulnerability, which causes a malicious DLL to load. We’ve observed a new cryptocurrency related campaign that abuses a legitimate Russian RAT known as Safib Assistant via a newer version of the malware called SpyAgent. While previous versions of the malware have been covered by other researchers, our blog entry focuses on the malicious actor’s latest attacks.
