North Korean Cyber Groups: A Web of Deception

=====================================================

In a shocking revelation, Mandiant has uncovered the existence of a complex network of North Korean cyber groups, each with its own unique malware and tactics. The findings suggest that these groups are not only sharing resources but also temporarily collaborating to achieve their goals.

The Rise of Bureau 325

According to sources, a new organization dubbed Bureau 325 was formalized in January 2021, just before North Korea’s Eighth Party Congress. This group is reportedly focused on COVID-19-related information and has been linked to the creation of malware such as PENCILDOWN.

Malware Sharing Across Groups

Mandiant’s research has uncovered a vast array of malware families being shared across different groups within the DPRK ecosystem. For example:

• APT43’s PENCILDOWN malware was found to have evolved into PENDOWN, used by suspected linked groups.
• Another instance of malware sharing was discovered between ROCKHATCH and HANGMAN.V2.

The Shifting Landscape

The years of public reporting on multiple DPRK aligned cyber units as the “Lazarus Group” moniker have come full circle. The shifting DPRK cyber landscape is increasingly characterized by resource sharing and temporary collaboration, making precise attribution more difficult.

Implications for Cybersecurity

As additional data is collected, it is likely that we will see increased fidelity in identifying these groups and their specialized targets. However, the web of deception spun by North Korea’s cyber groups remains a complex challenge to unravel.

What’s Next?

The report highlights the need for cybersecurity experts to adapt to this new landscape and stay vigilant against evolving threats.
