Regaining Trust in the PKI

The SSL PKI has been in use and implemented for 15 years now to secure online communications. From its initial proprosals and immediate growth, the need for secured online communications has been met with challenges. The infrastructure and protocol itself is showing signs of wear, with multiple attacks and corrections to the scheme itself. And in its 15th year, an alternative to the Cerificate Authority infrastructure is finally being given some competition with the release and debate around Convergence, an open source alternative to the current system of Certificate Authorities. Feel free to right click and download for the full sized version; the graphic below provides a list of some of the major events for SSL/TLS PKI in the past 15 years.

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.
