APT reports

A Glimpse Behind “The Mask”

The world of APTs is a colorful place. In 2012, we uncovered Flame, a massive cyberespionage operation infiltrating computers in the Middle East. Our research indicated a connection with the wellknown Stuxnet cyberweapon, designed to sabotage the Iranian nuclear program.In early 2013, we announced our research on RedOctober, a cyberespionage operation focusing on diplomatic institutions. In June 2013, we published our research on NetTraveler, and in September, our research on the Kimsuky attacks.

Our analysis of all these different APT operations indicated an unique use of languages, that offer clues regarding some of the people behind these operations. If the comments in the Flame C&C were written in English, artifacts in RedOctober indicated Russian speakers, NetTraveler indicated Chinese natives. Finally, Kimsuky indicated Korean speaking authors, which we linked to North Korea.

During the past months we have been busy analysing yet another sophisticated cyberespionage operation which has been going on at least since 2007, infecting victims in 27 countries. We deemed this operation “The Mask” for reasons to be explained later.

The “Mask” is leveraging high-end exploits, an extremely sophisticated malware which includes a bootkit and rootkit, Mac and Linux versions and a customized attack against Kaspersky products. This is putting them above Duqu in terms of sophistication, making it one of the most advanced threats at the moment.

Most interesting, the authors appears to be native in yet another language which has been observed very rarely in APT attacks.

We will present more details about the “Mask” APT next week at the Kaspersky Security Analyst Summit 2014 (on Twitter, #TheSAS2014).

Ferocious Kitten: 6 years of covert surveillance in Iran

Ferocious Kitten is an APT group that has been targeting Persian-speaking individuals in Iran. Some of the TTPs used by this threat actor are reminiscent of other groups, such as Domestic Kitten and Rampant Kitten. In this report we aim to provide more details on these findings.

Andariel evolves to target South Korea with ransomware

In April 2021, we observed a suspicious Word document with a Korean file name and decoy. It revealed a novel infection scheme and an unfamiliar payload. After a deep analysis, we came to a conclusion: the Andariel group was behind these attacks.

Operation TunnelSnake

A newly discovered rootkit that we dub ‘Moriya’ is used by an unknown actor to deploy passive backdoors on public facing servers, facilitating the creation of a covert C&C communication channel through which they can be silently controlled. The victims are located in Africa, South and South-East Asia.
