Incidents

Infected Valuehost servers

Yesterday, one of our users contacted us to tell us about the strange behaviour of his browser. He’d been looking at www.5755.ru – his browser opened a second web page, and his Web anti-virus warned him that a Trojan program was being downloaded.

The user went to this site after he’d seen it advertized on television. He almost fell victim to a malicious attack – the site’s homepage contained a script that downloads Trojan-Downloader.JS.Psyme.ct, which in turn downloads Trojan-Downloader.Win32.Tiny.eo. Of course, the malicious programs placed on the site change from day to day, but happyily, the Web anti-virus module in Kaspersky Anti-Virus 6.0 prevented this user from getting infected.

After investigating this a bit further, it turned out that at least 470 other servers had been subject to the same hacker attack. We found this out by entering a string from the script which had been injected into the site into Google.

All these servers had one thing in common – they were all hosted by Valuehost, the biggest hosting provider in Russia, which offers a home to more than 60,000 Russian web sites. Of course, the Valuehost administrators have been informed of the problem.

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.
