Red October – Indicators of compromise

Since our announcement about “Red October”, we’ve received a lot of questions on how to quickly identify compromised systems.

That’s why together with our partner Alienvault we’ve decided to put together a small whitepaper for CERTs and system administrators which can help identify and mitigate the attack.

The small whitepaper includes summarized information about malware’s known locations in infected systems, command and control domains and servers, snort rules, RC4 encryption keys, passwords and an industry standard IOC file with all these informations.

At the moment, our sinkhole is still registering traffic from 36 infected victims in several countries. We hope the information will help CERTs and admins to successfully identify and eradicate the infections.

The leap of a Cycldek-related threat actor

The investigation described in this article started with one such file which caught our attention due to the various improvements it brought to this well-known infection vector.

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.
