December patches and a 2007 retrospective

Today is ‘Patch Tuesday’ and this month Microsoft has announced that there will be seven security bulletins, three of which it rates ‘Critical’ and four of which it rates ‘Important’.

The Critical bulletins affect DirectX, Windows Media Format Runtime and Internet Explorer.

You can find more information here.

Make sure you patch your system. The easiest way to make sure you stay up-to-date is to enable Automatic Updates. You can find guidelines on applying Automatic Updates here.

The use of unpatched vulnerabilies continues to be a significant part of the threat landscape, so it’s no surprise that Micrsoft has been kept busy this year. Here’s a summary of this year’s patches.

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.
