A recently published article covers a major British bank’s refusal to implement two factor authentication: apparently the increased popularity of online banking shows that ‘customers already feel safe on the Internet’, without the need for extra hardware. But if the bank has the feeling that customers are blissfully happy, perhaps they should dig a little deeper.

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.
