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.

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.

What did DeathStalker hide between two ferns?

While tracking DeathStalker’s Powersing-based activities in May 2020, we detected a previously unknown implant that leveraged DNS over HTTPS as a C2 channel, as well as parts of its delivery chain. We named this new malware “PowerPepper”.
