APT (Targeted attacks)

CVE-2021-28310 is an out-of-bounds (OOB) write vulnerability in dwmcore.dll, which is part of Desktop Window Manager (dwm.exe). We believe it is exploited in the wild, potentially by several threat actors.

The investigation described in this article started with one such file which caught our attention due to the various improvements it brought to this well-known infection vector.

A41APT is a long-running campaign with activities detected from March 2019 to the end of December 2020. Most of the discovered malware families are fileless malware and they have not been seen before.

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.

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.

The detection logic has been improved in all our solutions to ensure our customers protection. We continue to investigate cyberattack on SolarWinds and we will add additional detection once they are required.

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.

Cyberspace conflicts can take a vast number of forms, but in the context of this article, we will only focus on two of them: cyber-warfare for intelligence purposes, and sabotage and interference with strategic systems in order to hinder a state’s ability to govern or project power.

As members of a global community, we often feel that we are failing to achieve an adequate level of cybersecurity. We believe it can be explained by a lack of global willpower, double-dealing activities, and the lack of global regulations. Here, we develop these hypotheses and outline ideas to advance cybersecurity.

We track the ongoing activities of more than 900 advanced threat actors. Here we try to focus on what we consider to be the most interesting trends and developments of the last 12 months.

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”.

Let us review the forecasts we made at the end of 2019 and see how accurate we were. Then we will go through the key events of 2020 relating to financial attacks. Finally, we need to make a forecast of financial attacks in 2021.

MATA framework, Garmin attack, Operation PowerFall, DeathStalker group and other events of 2020.

Trying to make predictions about the future is a tricky business. However, while we don’t have a crystal ball that can reveal the future, we can try to make educated guesses using the trends that we have observed over the last 12 months to identify areas that attackers are likely to seek to exploit in the near future.
