the in depth technical details
TL;DR; sigalarm handler calls syslog which isn't safe to call from a signal handler context.
Their example exploit needed about 10k attempts to get a remote shell so it's not fast or quiet, but a neat find regardless
I can already imagine the log generated will be a hint. We usually automate those anyway as it is closer to (D)DoS too.
