What is wiper malware?
Wiper malware destroys data instead of holding it for ransom: it overwrites files, disk structures or firmware so that systems cannot start or data cannot be recovered. It is used for sabotage, sometimes disguised as ransomware with a ransom note that leads nowhere, and companies can be hit as collateral damage when it spreads through shared suppliers or networks. Because there is nothing to negotiate, offline backups and a tested recovery plan are the only real answer. The steps before wiping are similar to other intrusions: access, command and control, movement to many machines, sometimes through central management tools that push the wiper everywhere at once. NetSenX does not detect the wiping itself, which happens on hosts; it watches the earlier steps, such as beaconing, scanning and lateral movement, on every plan.
