November Adobe Patches

This month’s Adobe Security Update round is a relatively quiet one, in contrast to the Microsoft patch cycle. There are two bulletins, one affecting Flash Player and one affecting ColdFusion.

After the discovery of a major breach at Adobe recently some would perhaps have expected a bigger number of CVEs to get patched this round. It will be interesting to see how the breach will affect patch cycles in the coming months.

The two CVEs affecting Flash Player and Adobe AIR both involve remote code execution vulnerabilities. Exploits for these vulnerabilities have so far not been observed in the wild. But given the popularity and criticality it’s important to roll out the patches as soon as possible.

The two vulnerabilities affecting ColdFusion have to do with XSS and remote-read vulnerabilities respectively. Just like with the Flash CVEs no exploits for these vulnerabilities have so far been seen in the wild.

For those with an Adobe ID – even if you didn’t receive an email from Adobe saying that your account credentials may have been compromised it’s still paramount that you change your password. It should go without saying that if the same password was used for other services they need to be changed there as well.

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.
