A new pro-Russian hacktivist group, known as ZPentest, has emerged, and has already made a significant impact on the cyber security landscape. This group has claimed responsibility for an OT attack in Arkansas City, USA, which targeted a water treatment facility. The attack was likely an attempt to disrupt critical infrastructure and demonstrate the group’s capabilities. The instant alliance formed between ZPentest, Cyber Army Russia and Noname05716, two other pro-Russian hacktivist groups, suggests a coordinated effort to destabilize the US. This suggests that the group may be an offshoot of one of the existing groups, rather than a completely new entity.
