DKnife Linux toolkit hijacks router traffic to spy, deliver malware
A newly discovered toolkit called DKnife has been used since 2019 to hijack traffic at the edge-device level and deliver malware in espionage campaigns. The framework serves as a post-compromise framework for traffic monitoring and adversary-in-the-middle (AitM) activities. It is designed to intercept and manipulate traffic destined for endpoints (computers, mobile devices, IoTs) on the network. […]
Ransomware gang uses ISPsystem VMs for stealthy payload delivery
Ransomware operators are hosting and delivering malicious payloads at scale by abusing virtual machines (VMs) provisioned by ISPsystem, a legitimate virtual infrastructure management provider. Researchers at cybersecurity company Sophos observed the tactic while investigating recent ‘WantToCry’ ransomware incidents. They found the attackers used Windows VMs with identical hostnames, suggesting default templates generated by ISPsystem’s VMmanager. Diving deeper, […]
