Paypal wins patent for crypto ransomware defense

posted 4 months ago
Online payments giant PayPal has been awarded a patent this week for a technique that could detect a type of crypto malware and mitigate its effects. The patent outlines how taking advantage of existing system data caches can help detect ransomware and prevent it from irretrievably locking up victims’ files.

The patent explains: “By detecting that ransomware is operating on a computer (e.g. by correlating between the original data and content in different cache layers), the negative effects of the ransomware may be mitigated or avoided.” The document also mentioned, one way users such as consumers and small businesses can avoid data loss is by backing up data.
