Participants of the operation told how Microsoft eliminated the infrastructure of the ZLoader botnet

Last week, Microsoft, ESET, Black Lotus Labs, Palo Alto Networks, Health-ISAC and Financial Services-ISAC took control of the infamous ZLoader botnet following an injunction issued by the U.S. Court for the Northern District of Georgia.

In the end, the company seized control of 65 hard-coded domains that ZLoader operators use to control the botnet, as well as 319 more DGA-registered domains that the hackers used to create redundant communication channels.

Let me remind you that around the same time, another Botnet Fodcha Attacks More Than 100 Victims Daily.

Zloader (aka Terdot или DELoader) is a well-known banking Trojan that was first discovered back in August 2015 during attacks on clients of several British financial companies. Its capabilities include capturing screenshots, harvesting cookies, stealing credentials and banking information, conducting reconnaissance on the device, triggering “pinning” mechanisms on the device, providing remote access to attackers, и така нататък. The malware is almost entirely based on the source code of the Zeus троянски, which leaked over a decade ago.

At first, the malware was actively used to attack banks around the world, from Australia and Brazil to North America, and its ultimate goal was to collect financial data using web injections and social engineering in order to trick infected bank customers into giving up their authentication codes and credentials.

But in recent years, Zloader has evolved to include many other features, such as being able to act as a backdoor and give hackers remote access to an infected system, and it can also be used as a malware loader and to install additional payloads.
