A Post-PC BlackHat?

This year’s BlackHat had a particularly wide range of topics. A more diverse range of topics means that more targets are under attack. This should come as no surprise.

On the one hand companies like Microsoft and Google have hardened their software against easy vulnerability exploitation.
On the other hand we’re seeing a plethora of new (types of) devices getting equipped with network connectivity. Those devices come with limited or no built-in security.

This focus on embedded devices is also reflected in the amount of research done on the embedded devices within our phones and personal computers. There was a demonstration of a practical attack against smartphone baseband processors over the OMA DM protocol. The lack of built-in security, or the ability to easily add security controls, again demonstrates this major weakness in today’s defense capabilities.

My colleague Vitaly Kamluk demonstrated, together with Anibal Sacco from Cubica Labs, how Computrace, popular low-jacking software, can be leveraged by attackers to perform remote code execution. Short of disabling the feature, which sometimes isn’t even possible, there’s no easy mitigation.

We’re increasingly relying on more technology that can only be somewhat reliably protected by turning it off. This is not a sustainable path. While I appreciate that our personal operating systems appear to be getting safer, I’m rather pessimistic for the post-PC world.

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.
