Danger of infection increasing year by year

In spite of the steps taken by IT industry, the evolution of the Internet is
accompanied by the evolution of malicious code. Proof of this is our statistics on the number of new entries to the signature base for Kaspersky Anti-Virus.

Number of signatures added to Kaspersky Anti-Virus database every year
(2001 – 2004)

Our graph shows that the number of malicious programs continues to increase. And it seems certain that this trend will continue – and we will continue to detect increasing numbers of viruses, worms, Trojans and other malicious programs.

We will be publishing some more detailed statistics on our antivirus databases in the near future. Watch this site…

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.
