Abstract
A system (200) detects transmission of potentially malicious packets. The system (200) receives, or otherwise observes, packets and generates hash values based on variable-sized blocks of the packets. The system (200) then compares the generated hash values to hash values associated with prior packets. The system (200) determines that one of the received packets is a potentially malicious packet when one or more of the generated hash values associated with the received packet match one or more of the hash values associated with the prior packets.
