It’s the end of 2011 as we know it, and Microsoft feels fine finishing out the year with a handful of out-of-band holiday patches. This round is important not because the vulnerabilities directly impact massive numbers of customers and their online behavior on Windows laptops, tablets, and workstations, but because ASP.NET maintains vulnerable code allowing for easy DoS of hosting websites, authentication bypass techniques, and stealth redirections to other websites (most dangerously those sites host phish and hosting client side exploits). All of this could curdle your eggnog in the coldest of weather.

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.

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.

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.

While tracking DeathStalker’s Powersing-based activities in May 2020, we detected a previously unknown implant that leveraged DNS over HTTPS as a C2 channel, as well as parts of its delivery chain. We named this new malware “PowerPepper”.
