100 Days of YARA – Day 13: Quasar RAT

While browsing Malware Bazaar, I saw some recent uploads of Quasar RAT samples. I encounter this RAT at work sometimes. https://bazaar.abuse.ch/browse/tag/QuasarRAT/

The Quasar project has been active for a while on GitHub: https://github.com/quasar/Quasar

Here are some links that I have bookmarked and tagged as quasarrat which may be interesting: https://pinboard.in/u:droberson/t:quasarrat/
