Imperva was able to replicate the same behavior using a technique called UPnP Port Masking, which uses the Universal Plug and Play (UPnP) Protocol to alter the source port of commonly abused network protocols in DDoS attacks. Multiple news outlets picked up on Imperva’s research and … More ? The post Why you shouldn’t be worried about UPnP port masking appeared first on Help Net Security .

Jaku: Analysis of a botnet

In May 2016, the Special Investigations team at Forcepoint revealed the existence of a botnet campaign that is unique in targeting a very small number of individuals while in tandem, herding thousands of victims into general groups. The discovery, known as Jaku, offers vital insight into the workings and characteristics of a botnet, as well as specific understanding of a targeted attack that differs from the scattergun approach of broader botnet activities. It also sheds … More ?
