  8. BlackTech APT Deploys BlueShell Linux Backdoor Against Japanese Organizations

    News Cyber Security News4h ago3 sources

    BlackTech has been linked to a newly examined Linux backdoor deployment against organizations in Japan, showing how a familiar remote-access tool can be reshaped for cyberespionage. The malware gives intruders a way to run commands, move files, and route traffic after they have already entered a network, raising the risk to internal systems and sensitive data. The attack begins after the attackers gain access and move laterally through the victim environment using SSH. From there, they deploy a loader that launches the backdoor, a method that reflects the group’s established interest in…

  9. ShutterGap Exposes Millions of AWS Resources Between Cloud Security Scans

    News Cyber Security News7h ago3 sources

    Cloud security teams often utilize Cloud Security Posture Management (CSPM) and Cloud-Native Application Protection Platform (CNAPP) tools to identify risky configurations. However, new research from Aryon Security reveals that this approach may overlook a significant class of threats: temporary AWS resources that are publicly exposed but removed before the next scan occurs. Aryon refers to this visibility gap as “ShutterGap.” It happens when a cloud resource is made public for a brief period, sometimes lasting only a few minutes. Attackers can continuously monitor public AWS resources…
