25,000-strong CCTV botnet used for crippling DDoS attacks

Cybercriminals add DDoS component to ransomware payloads

Instead of just encrypting data files on a workstation (plus any network drive it can find) and locking the machine, a new variant of the Cerber ransomware is now adding a DDoS bot that can quietly blast spoofed network traffic at various IPs, according to KnowBe4. This is the first time DDoS malware has been bundled within a ransomware infection. It means that while the victim is unable to access their endpoint, that same endpoint … More ?

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 ?
