Insecure Internet-connected devices have aided different types of cybercrime for years, most common being DDoS and spam campaigns. But cybercriminals have now shifted toward a profitable scheme where botnets do not just launch DDoS or spam—they mine cryptocurrencies as well.
Smominru, an infamous cryptocurrency-mining and credential-stealing botnet, has become one of the rapidly spreading computer viruses that is now infecting over 90,000 machines each month around the world.
Though the campaigns that are hacking computers with the Smominru botnet have not been designed to go after targets with any specific interest, the latest report from Guardicore Labs researchers shed light on the nature of the victims and the attack infrastructure.
According to the researchers, just last month, more than 4,900 networks were infected by the worm without any discrimination, and many of these networks had dozens of internal machines infected.
