Open up – police!

I’m just back from a business trip to the Baltics. And I heard an interesting story there.

In one of the Baltic states, a well known local IT specialist ran into some trouble with the police. He’s got ADSL at home, shared with a neighbour – there’s one line for two apartments, or two houses. Early in the morning this man and his neighbour were woken by the police, and all their computers were arrested. Why? The neighbour’s computer was infected by a Trojan, and this Trojan conducted a DoS attack on a web site. So the company that owns the site makes a statement to the police. The police investigate, find the computer conducting the attack. And then decide to act by appearing at seven in the morning and taking not only the infected computer but the neighbour’s computer as well…

So we can see that Trojans and viruses are now doing damage in a new way. Maybe users will be investigated by the police, and have their computers arrested…

Here’s a list of all the known ways that a computer virus can cause damage – for personal and business users:

1. Computers and networks start to function in unstable way
2. Data is destroyed
3. Confidential information is stolen
4. Volume of traffic increases
5. Computers are seized in police investigations

Reports

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.
