Kaspersky's analysis of the CopyFail vulnerability:
"Information about the Copy Fail vulnerability, which allows attackers to gain root access on virtually any modern Linux distribution":
https://securelist.com/tr/copyfail-root-linux/119634/
Note that the article talks about detecting Python launching the PoC. This is not good enough, given that Go and Rust implementations already exist. One should monitor for command lines launching SUID binaries (which, admittedly, the article also suggests - but again limits itself to Python), although this might case false positives.
