This malware affects 4,700 computers every day

Security researchers have discovered that the Smominru malware infected 90,000 machines worldwide during the month of August, with an infection rate of up to 4,700 computers per day.

In its post-infection phase, it steals victim credentials, installs a Trojan module and a cryptominer and propagates inside the network, according to researchers from Guardicore, a data centre and cloud security company.

The botnet uses several methods to propagate, but primarily it infects a system in one of two ways — either by brute-forcing weak credentials for different Windows services, or more commonly by relying on the infamous EternalBlue exploit, cybersecurity firm Kaspersky said in a blog post last week.
