Paper: Spreading techniques used by malware

Posted by   Martijn Grooten on   Dec 21, 2016

Malware infections usually start with a user opening an attachment, visiting a link, or simply accessing an infected site with a vulnerable browser. But once malware has infected an endpoint, it often looks for other devices in order to spread further, or at least to include the files on those devices in its malicious encryption efforts.

Today, we publish a short paper by Acalvio researcher Abhishek Singh, who uses examples from recent ransomware samples to show how malware spreads within a network ('lateral movement') or even outside the network. You can read the paper either in HTML or PDF format.
