Incidents

Like clockwork

The situation with phishing runs targeted at Dutch banks has remained the same throughout 2006 – very quiet. I started noticing that the criminals were strategically planning their attacks by mostly using holidays to carry out their spam runs. By doing this they were hoping to increase the response time of the people involved in combatting these threats.

Just as I had expected there was a phishing run against the Dutch Postbank on Monday, the first day of Christmas. Although it was Christmas the overall response time from the parties involved didn’t really suffer. So that’s good.

We detected the phishing sample proactively as Trojan-Spy.HTML.Fraud.gen.

Today we noticed an interesting side effect of this phishing run.

The link in the adress bar is the one spoofed in the phishing email. Firefox makes use of Google’s anti-phishing database. Seeing as the fraudulent site is also detected Google accidentily added both sites to the database.

We’ve reported this to Google. Let’s hope this gets fixed soon as quite a lot of Dutch people are worried about this.

Btw, there seems to be some bug in Firefox. For currently unknown reasons Firefox 2.0.0.1 only flags the site after switching tabs.

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.
