Microsoft Updates November 2012 – IE, Kernel+Shell, and .NET Critical Patches

Microsoft is patching a fair number of vulnerabilities in their software with 19 flaws being fixed. All of them are being updated in six Bulletins this month (MS12-071 through MS12-076). Four of the Bulletins are rated critical with only two of them being rated urgent for immediate deployment by larger customers concerned with compatibility and performance. At the same time, Internet Explorer 10 is not vulnerable to exploitation by the related set of three flaws, and newly released Windows 8 is affected by yet another font parsing flaw described by CVE-2012-2897, similar to the vulnerability exploited by Duqu. The font malware is especially interesting because the Duqu exploit is currently being included in mass exploitation kits alongside widespread Java and Adobe Reader exploits to spread Ransomware, ZeroAccess, and other trojans of all sorts. Even though Duqu was spread years ago, the patch delivered months ago, the vulnerability continues to be included in the kits and successfully exploited

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.
