Linux malware attacks are on the rise, and businesses aren't ready for it

Cyber criminals are increasingly targeting Linux servers and cloud infrastructure to launch ransomware campaigns, cryptojacking attacks and other illicit activity – and many organisations are leaving themselves open to attacks because Linux infrastructure is misconfigured or poorly managed. 

Analysis from cybersecurity researchers at VMware warns that malware targeting Linux-based systems is increasing in volume and complexity, while there’s also a lack of focus on managing and detecting threats against them. This comes after an increase in the use of enterprises relying on cloud-based services because of the rise of hybrid working, with Linux the most common operating system in these environments.

That rise has opened new avenues that cyber criminals can exploit to compromise enterprise networks, as detailed by the research paper, including ransomware and cryptojacking attacks tailored to target Linux servers in environments that might not be as strictly monitored as those running Windows.

These attacks are designed for maximum impact, as the cyber criminals look to compromise as much as the network as possible before triggering the encryption process and ultimately demanding a ransom for the decryption key.
