Crowdstrike is reporting that malware targeting Linux has increased considerably in 2021:
Malware targeting Linux systems increased by 35% in 2021 compared to 2020.
XorDDoS, Mirai and Mozi malware families accounted for over 22% of Linux-targeted threats observed by CrowdStrike in 2021.
Ten times more Mozi malware samples were observed in 2021 compared to 2020.
Lots of details in the report.
The Crowdstrike findings aren’t surprising as they confirm an ongoing trend that emerged in previous years.
For example, an Intezer report analyzing 2020 stats found that Linux malware families increased by 40% in 2020 compared to the previous year.
In the first six months of 2020, a steep rise of 500% in Golang malware was recorded, showing that malware authors were looking for ways to make their code run on multiple platforms.
This programming, and by extension, targeting trend, has already been confirmed in early 2022 cases and is likely to continue unabated.
