BlackCat Ransomware Raises Ante After FBI Disruption

The U.S. Federal Bureau of Investigation (FBI) disclosed today that it infiltrated the world's second most prolific ransomware gang, a Russia-based criminal group known as ALPHV and BlackCat.

Meanwhile, BlackCat responded by briefly "unseizing" its darknet site with a message promising 90 percent commissions for affiliates who continue to work with the crime group, and open season on everything from hospitals to nuclear power plants.

GHSA-7ww5-4wqc-m92c: containerd allows RAPL to be accessible to a container

# /sys/devices/virtual/powercap accessible by default to containers Intel's RAPL (Running Average Power Limit) feature, introduced by the Sandy Bridge microarchitecture, provides software insights into hardware energy consumption. To facilitate this, Intel introduced the powercap framework in Linux kernel 3.13, which reads values via relevant MSRs (model specific registers) and provides unprivileged userspace access via `sysfs`. As RAPL is an interface to access a hardware feature, it is only available when running on bare metal with the module compiled into the kernel. By 2019, it was realized that in some cases unprivileged access to RAPL readings could be exploited as a power-based side-channel against security features including AES-NI (potentially inside a SGX enclave) and KASLR (kernel address space layout randomization). Also known as the [PLATYPUS attack](https://platypusattack.com/), Intel assigned [CVE-2020-8694](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-8694)...
