Hiding in the Tunnels: Unmasking the New Stealthy BPFDoor Variants

This is Rapid7's whitepaper discussing BPFDoor variants. Advanced persistent threats APTs are locked in a continuous arms race with network defenders. As static indicators of compromise IoCs for the notorious BPFDoor malware became widely deployed by security vendors, the threat actors went back ...

SPARK: Secure Predictive Autoscaling for Robust Kubernetes

Achieving high availability and robust security in Kubernetes requires more than reactive scaling and standard perimeter firewalls. Traditional autoscalers, such as HPA, often fail to react quickly to traffic spikes and cannot distinguish between legitimate flash crowds and DDoS attacks. We prese...

Malware in sbrugna...

The vulnerability of the kernel-level driver nvlddmkm.sys from NVIDIA’s graphics processing units, including GeForce, Quadro, NVS, and Tesla, allows attackers to cause system failures or gain unauthorized access to protected information.

The vulnerability of the kernel mode driver nvlddmkm.sys of NVIDIA’s graphics processing units, including GeForce, Quadro, NVS, and Tesla, relates to reading beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause system failures or gain unauthorized...

How ToddyCat tried to hide behind AV software

To hide their activity in infected systems, APT groups resort to various techniques to bypass defenses. Most of these techniques are well known and detectable by both EPP solutions and EDR threat-monitoring and response tools. For example, to hide their activity in Windows systems, cybercriminals...

Advanced threat predictions for 2025
