On Feb. 4, Linux announced CVE-2022-0492, a new privilege escalation vulnerability in the kernel. CVE-2022-0492 marks a logical bug in control groups (cgroups), a Linux feature that is a fundamental building block of containers. The issue stands out as one of the simplest Linux privilege escalations discovered in recent times: The Linux kernel mistakenly exposed a privileged operation to unprivileged users.
Earlier today, I received a scam email that impersonates the Ukrainian Red Cross. It attempts to solicit donations via Bitcoin. The email is almost certainly not related to any valid Red Cross effort.
There are some legitimate efforts to collect donations for Ukraine using crypto-currencies. This scam may take advantage of these efforts.
