Spam and phishing mail

Upsurge in attacks using Dutch

I must say that there are interesting times in the Netherlands. Normally we don’t see Dutch used often in spam and phishing emails, but there’s been a real spike the last 10 days.

It began last week on Monday with two simultaneous spam runs in Dutch: one about a supposed nuclear accident in Amsterdam and one purportedly from a girl called Polina who was in need of a ‘friend’. Both of these spam runs tried to convince the user to install one and the same codec, which in reality was a Trojan-Spy.Win32.Zbot variant.

After this incident there was a spam run in Dutch concerning This site claimed to be part of the Aids foundation and was asking for donations. Obviously this was a fraud.

And then last night I saw a Dutch phishing email trying to steal Windows Live logins. We’ve notified the local CERT and hope that the site gets taken down promptly.

The quality of the Dutch varies from incident to incident, but overall has greatly improved over the attacks from six months ago. The Windows Live phishing email was an exception: it was written rather badly. However, the sad reality could be that the attackers are trying to mimic teenage slang as part of their social engineering strategy.

If these incidents are a sign of more to come than I foresee 2008 being a very interesting year for Dutch users.

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.
