A court order obtained by Microsoft allowed the company to take over 65 hardcoded domains used by the ZLoader group to control botnets, and another 319 domains registered using the domain generation algorithm used to create backup communication channels.

Microsoft said its researchers have identified one of the criminals behind the ZLoader botnet component used to distribute ransomware. It is about Denis Malikov, who lives in Simferopol, on the Crimean peninsula.

“We have decided to name a person in connection with this case in order to make it clear that cybercriminals will not be allowed to hide behind the anonymity of the Internet to commit their crimes,” said Amy Hogan-Bernie, DCU director.

ESET, Black Lotus Labs, Palo Alto Networks Unit 42 and Avast also took part in the Microsoft-led investigation.

ZLoader can take screenshots, collect cookies, steal passwords and bank account information, it can be used for reconnaissance, disabling legitimate security tools and providing remote access to attackers. ZLoader is almost entirely based on the source code of the Zeus v2 Trojan that leaked more than a decade ago.

The malware was used to attack banks around the world, with the ultimate goal of collecting financial data. ZLoader can also function as a backdoor and provide remote access to attackers, and can also be used to load other malware on infected devices.

It has recently been used to distribute ransomware such as Ryuk, Egregor, DarkSide and BlackMatter.
