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.

Lazarus targets defense industry with ThreatNeedle

In mid-2020, we realized that Lazarus was launching attacks on the defense industry using the ThreatNeedle cluster, an advanced malware cluster of Manuscrypt (a.k.a. NukeSped). While investigating this activity, we were able to observe the complete life cycle of an attack, uncovering more technical details and links to the group’s other campaigns.

Sunburst backdoor – code overlaps with Kazuar

While looking at the Sunburst backdoor, we discovered several features that overlap with a previously identified backdoor known as Kazuar. Our observations shows that Kazuar was used together with Turla tools during multiple breaches in past years.

Lazarus covets COVID-19-related intelligence

As the COVID-19 crisis grinds on, some threat actors are trying to speed up vaccine development by any means available. We have found evidence that the Lazarus group is going after intelligence that could help these efforts by attacking entities related to COVID-19 research.

Sunburst: connecting the dots in the DNS requests

We matched private and public DNS data for the SUNBURST-malware root C2 domain with the CNAME records, to identify who was targeted for further exploitation. In total, we analyzed 1722 DNS records, leading to 1026 unique target name parts and 964 unique UIDs.
