Blogging bad for you?

Weblogs are springing up all over the place, on every topic under the sun. And not surprisingly, blogs have drawn the attention of virus writers as a new way of infecting computers. A recent report shows that blogs are being used to install viruses, keyloggers and other malicious code.

So should we close our blog? Or tell you to stop reading weblogs altogether?

I don’t think so. But weblogs are a potential threat, so here are our guidelines on how to protect your computer.

  • Anti-virus software is a must!
  • You must keep your anti-virus software up-to-date. Choose a vendor that provides frequent updates and make sure that you download the latest update.
  • Don’t trust any information from unknown sources: this includes email, instant messaging programs, FTP, and the Internet [e.g. weblogs!].
  • Be very wary of unusual or strange information, even if you seem to have received it from a trusted source.
  • Pay careful attention to information from reputable anti-virus companies. We’re able to give prompt warning about new threats.

In short: use the latest anti-virus protection and be very very careful who you trust…

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.
