Cobalt Strike 4.12: Fix Up, Look Sharp!
#cobaltstrike
Cobalt Strike 4.12 is now available. We are excited to introduce a new look and feel for the Cobalt Strike GUI, a REST API, User Defined Command and Control (UDC2), new process injection options, new UAC bypasses, a new BOF API BeaconDownload for in-memory buffers, and new drip loading Malleable C2 options. Additionally, we have overhauled pivot Beacons so that they now support the novel Sleepmask introduced in 4.11, fixed [...]

The REST API was a major feature of the 4.12 release and forms part of a broader ongoing change in the Cobalt Strike ecosystem. Therefore, we wanted to dedicate a blog post to explain the rationale behind it, discuss the architecture, and provide hands-on examples to get our customers up and running. In addition to [...]

What Will Shape Cybersecurity in 2026: AI Speed, Expanding Attack Surfaces, and Specialized Red Teams
#bishopfox
2026 will hit cybersecurity like a fast-forward button: AI moves quicker than governance, attack surfaces sprawl into the physical world, and red teams get hyper-specialized. Here’s what’s coming—and how to stay ahead before “optional” becomes “too late.”

Linux Process Injection via Seccomp Notifier
#outflank
This post demonstrates the use of seccomp user notifications to inject a shared library into a Linux process. I haven’t seen this combination documented as a process injection technique before, and it has some benefits over alternatives. In summary, seccomp user notifications enable user-space injection from parent to child without any
1. Seccomp user notifications were introduced in Linux kernel version 5.0, but this PoC relies on
2. Requires you to create the target process (parent-to-child injection only).
3. The injected code runs with the same UID, namespaces, and LSM label as the target process.

I haven’t seen this combination documented as a process injection technique before, and it has some benefits over alternatives. In summary, seccomp user notifications enable user-space injection from parent to child without any
LD_* environment variables or privileged capabilities, regardless of the ptrace_scope configuration. However, seccomp user notifications have some notable limitations:1. Seccomp user notifications were introduced in Linux kernel version 5.0, but this PoC relies on
SECCOMP_ADDFD_FLAG_SEND (Linux 5.14+) to avoid TOCTOU issues when hooking openat.2. Requires you to create the target process (parent-to-child injection only).
3. The injected code runs with the same UID, namespaces, and LSM label as the target process.
