The IPStorm botnet, which was first spotted targeting Windows systems last year, has quadrupled in size to reach 13,500 infected systems - and is now targeting Linux, Android and Mac devices.


Furthermore, the botnet has also quadrupled in size, growing from around 3,000 infected systems in May 2019 to more than 13,500 devices this month.

These latest developments put IPStorm in the class of today's most dangerous botnets, a classification the malware deserves due to its sustained development across the past year, expansion to multiple platforms, and for the advanced and unique features it possesses.
