Gozi ISFB, also known as Ursnif and Dreambot, is a malicious software (malware) that has been actively developed and distributed worldwide. This malware is designed to exploit computer systems, primarily targeting the banking and financial sectors by stealing passwords and credentials from victims. The Gozi ISFB variant exhibits persistence in victim networks using command and control (C&C) domains, bot version, Group ID, RSA key, and Serpent encryption keys. It was observed to be one of the most active banking Trojans circulated through emails and exploit kits. Notably, the source code for this variant was leaked between 2013 and 2015, which has contributed to its widespread use and continuous development. The threat actor behind Gozi ISFB offers fast flux on infected computers particularly in Asia, Africa, and the Middle East, making it challenging to block content due to frequently changing IP addresses. This operation has been linked to numerous ransomware variants such as Bad Rabbit, GandCrab, LockBit 2.0, and STOP/DJVU, and several other malware samples including BankBot, Dreambot, Godzilla, Nymaim, Pony Loader, Privateloader, and SmokeLoader. Interestingly, Gozi ISFB's code was found to be quite basic and similar to those used by other malware families like Netwalker, ZLoader, and Smokeloader. In a significant shift, INDRIK SPIDER, a cybercriminal group, started using a variant of Gozi ISFB instead of their Dridex banking trojan in their operations. This transition marked a new era for the group approximately six months after the Office of Foreign Assets Control (OFAC) sanctions and the unsealing of the indictment against Yakubets and Turashev. During this period, WastedLocker was deployed in the first BGH campaign, indicating an evolution in the cybercrime landscape.
