It was as if the attackers were purposely buying up domains, but such a scenario always seemed to us too complicated. --------------------------------------------- https://securelist.com/redirect-auction/96944/ ∗∗∗ F5 BigIP vulnerability exploitation followed by a backdoor implant attempt, (Tue, Jul 7th) ∗∗∗ --------------------------------------------- While monitoring SANS Storm Center's honeypots today, I came across the second F5 BIGIP CVE-2020-5902 vulnerability exploitation followed by a backdoor deployment attempt.

It used virtualization that prevented us from producing a fully-deobfuscated memory dump for static analysis. Statically analyzing a large virtualized sample can take anywhere from several days to several weeks. Bypassing this time-consuming step presented an opportunity for collaboration between the FLARE reverse engineering team and [...] --------------------------------------------- http://www.fireeye.com/blog/threat-research/2020/07/configuring-windows-dom… ∗∗∗ Mac ThiefQuest malware may not be ransomware after all ∗∗∗ --------------------------------------------- We discovered a new Mac malware, ThiefQuest, that appeared to be ransomware at first glance.

Most of the exploits can be considered recognizance. We only saw one working exploit installing a backdoor. Badpackets reported seeing a DDoS bot being installed. --------------------------------------------- https://isc.sans.edu/diary/rss/26316 ∗∗∗ Vulnerability Management Maturity Model ∗∗∗ --------------------------------------------- I get it. You dread going into the office sometimes. It isn’t that you don’t like the people or the location. It’s that beast, waiting for you when you arrive, and it never seems to go away. You work hard at it, but you never seem to get ahead. You are responsible for the vulnerability management program within your organization. Either as part of a formal program or on an ad-hoc basis, it’s your baby. Except that it isn’t a baby, it is more of an untameable monster, a minotaur in the labyrinth, waiting to surprise you as you turn the corner. --------------------------------------------- https://www.sans.org/blog/vulnerability-management-maturity-model ∗∗∗ Vulnerabilities Digest: June 2020 ∗∗∗ --------------------------------------------- Highlights for June 2020 Cross site scripting is still the most common vulnerability in WordPress Plugins. Bad actors are taking advantage of the lack of restrictions in critical functions and issues surrounding user input data sanitization. Massive local file inclusion (LFI) attempts have been discovered attempting to harvest WordPress and Magento credentials.
