Ferocious Kitten is an APT group that since at least 2015 has been targeting Persian-speaking individuals who appear to be based in Iran. Although it has been active for a long time, the group has mostly operated under the radar and has not been covered by security researchers to the best of our knowledge. It is only recently that it drew attention when a lure document was uploaded to VirusTotal and went public thanks to researchers on Twitter. Since then, one of its implants has been analyzed by a Chinese threat intelligence firm.
