Signature polymorphic methods

WebIt can be divided into two main techniques: signature-based techniques and anomaly-based techniques. Signature-based detection is the older technology, dating back to the 1990s, and is very effective at identifying known threats. Each signature is a string of code or pattern of actions that corresponds to a known attack or malicious code. WebMar 29, 2016 · Modern detection techniques are not adequate against this rapidly-mutating polymorphic malware. The age-old approach of signature-based detection is the only one that has the highest detection rate in real time and is used by almost all antivirus software products. The process of current signature extraction has so far been by manual evaluation.
