The findings come from German cybersecurity firm DCSO, which linked the exercise as originating from the Democratic Folks’s Republic of Korea (DPRK)-nexus actors focusing on Russia.
The Konni (aka Opal Sleet, Osmium, or TA406) exercise cluster has a longtime sample of deploying Konni RAT towards Russian entities, with the menace actor additionally linked to assaults directed towards MID a minimum of since October 2021.
In November 2023, Fortinet FortiGuard Labs revealed the usage of Russian-language Microsoft Phrase paperwork to ship malware able to harvesting delicate data from compromised Home windows hosts.
DCSO stated the packaging of Konni RAT inside software program installers is a method beforehand adopted by the group in October 2023, when it was discovered to leverage a backdoored Russian tax submitting software program named Spravki BK to distribute the trojan.
“On this occasion, the backdoored installer seems to be for a instrument named ‘Statistika KZU’ (Cтатистика КЗУ),” the Berlin-based firm stated.
