Phishing on the rise

Over the past week we saw more and more phishing emails every day. A major European ISP told us that within 24 hours they scanned 16 million messages and 268,000 were phisihng scams. And this wasn’t one scam – there were many different messages targeting companies including Citibank, US Bank, EBay, Pay Pal and Sun Trust.

Possibly, the recent outbreaks by Bagle.at and Bagle.au supported this flood, since these Bagles created new bot networks for spammer use.

On the other hand, the computer underground may be taking revenge for the successful arrests of fellow cyber criminals over the past several months around the globe.

We are monitoring the situation, but do caution users to be extra careful about answering emails from financial institutions.

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.
