UNC5325 has been observed deploying LITTLELAMB.WOOLTEA, PITSTOP, PITDOG, PITJET, and PITHOOK. Mandiant identified TTPs and malware code overlaps in LITTLELAMB.WOOLTEA and PITHOOK with malware leveraged by UNC3886. Mandiant assesses with moderate confidence that UNC5325 is associated with UNC3886.",
