More on safe browsing

Firefox 1.0 Just at the time three variants of Bofra (previously detected by us as Mydoom) started spreading thanks to a brand new exploit in Microsoft’s Internet Explorer, Mozilla Foundation released version 1.0 of Firefox, their free Internet browser.

With IE becoming more and more complex, filled with tons of undocumented features (read bugs) and being the number one target for malware developers worldwide, now may be a really good time to try an alternative – if you haven’t already.

From this point of view, Firefox seems to be a nice replacement. At least until major vulnerabilities start to be found in it as well.

You can download Firefox 1.0 here.

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.
