Malware Victim Selection Through WiFi Identification, (Tue, Dec 22nd)

Last week, I found a malware sample that does nothing fancy, it&#;x26;#;39;s a data stealer but it has an interesting feature. It&#;x26;#;39;s always interesting to have a look at the network flows generated by malware samples. For a while, attackers use GeoIP API services to test if the victim&#;x26;#;39;s computer deserves to be infected… or not!

Since we could all probably use a little distraction from the current Solarigate/SUNBURST news[1,2,3], I thought it might be good to look at something a little bit more positive today. Specifically, at how patching of CVE-2019-19781 AKA “Shitrix” AKA “one of the more famous named vulnerabilities from the end of 2019” went.
