Spam and phishing mail

Free turkey for all!

Americans having been planning their Thanksgiving meal for a while, and the spammers haven’t been idle.

They’ve not only been offering recipes:

but the ingredients for them too! Order a mass mailing, and get coupons for a free turkey! (What’s kind of intriguing is that the mass mailing on offer is traditional, paper-based advertising, rather than the electronic kind.)

All the emails we’ve been filtering show the spammers are jumping on the bandwagon of tradition to flog their usual goods and services. But they’ve broken with tradition in one way – rather than waiting till Black Friday to launch their sales, they’ve started early.

Free turkey for all!

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.
