SambaCry is coming

Not long ago, news appeared online of a younger sibling for the sensational vulnerability EternalBlue. The story was about a new vulnerability for *nix-based systems – EternalRed (aka SambaCry). On May 30th our honeypots captured the first attack to make use of this particular vulnerability, but the payload in this exploit had nothing in common with the Trojan-Crypt that was EternalBlue and WannaCry.

Research

50 hashes per hour

In this research we’ll be revisiting the USB port – this time in attempts to intercept user authentication data on the system that a microcomputer is connected to. As we discovered, this type of attack successfully allows an intruder to retrieve user authentication data – even when the targeted system is locked.

Unraveling the Lamberts Toolkit

The Lamberts is a family of sophisticated attack tools that has been used by one or multiple threat actors against high-profile victims since at least 2008. The arsenal includes network-driven backdoors, several generations of modular backdoors, harvesting tools, and wipers.

Incidents

Beware of Backdoored Linux Mint ISOs

Yesterday a blog post on “The Linux Mint Blog” caught our attention. Apparently criminals managed to compromise a vulnerable instance of Wordpress which the project used to run their website. The attackers modified download links pointing to backdoored ISO files of Linux Mint 17.3 Cinnamon edition.

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.
