Threat actors are using stolen NVIDIA code signing certificates to sign malware to appear trustworthy and allow malicious drivers to be loaded in Windows.

This week, NVIDIA confirmed that they suffered a cyberattack that allowed threat actors to steal employee credentials and proprietary data.

If you use an Apple Macbook, it’s likely that you have a secret enclave for important secrets — such as your encryption keys. These keys define the core of the trust infrastructure on the device — and protect applications from stealing these secrets. The TEE also allows isolation between code which is fully trusted, and code that cannot be fully trusted. If this did not happen, we could install applications on our computer which would discover our login password and steal the encryption used used to key things secret and trusted.

On Feb. 4, Linux announced CVE-2022-0492, a new privilege escalation vulnerability in the kernel. CVE-2022-0492 marks a logical bug in control groups (cgroups), a Linux feature that is a fundamental building block of containers. The issue stands out as one of the simplest Linux privilege escalations discovered in recent times: The Linux kernel mistakenly exposed a privileged operation to unprivileged users.

Earlier today, I received a scam email that impersonates the Ukrainian Red Cross. It attempts to solicit donations via Bitcoin. The email is almost certainly not related to any valid Red Cross effort.
There are some legitimate efforts to collect donations for Ukraine using crypto-currencies. This scam may take advantage of these efforts.

Researchers have disclosed details of a new security vulnerability in GitLab, an open-source DevOps software, that could potentially allow a remote, unauthenticated attacker to recover user-related information.

• Proofpoint has identified a likely nation-state sponsored phishing campaign using a possibly compromised Ukrainian armed service member’s email account to target European government personnel involved in managing the logistics of refugees fleeing Ukraine.
• The email included a malicious macro attachment which attempted to download a Lua-based malware dubbed SunSeed.
• The infection chain used in this campaign bears significant similarities to a historic campaign Proofpoint observed in July 2021, making it likely the same threat actor is behind both clusters of activity.
• Proofpoint is releasing this report in an effort to balance accuracy with responsibility to disclose actionable intelligence during a time of high-tempo conflict.

Activity in the digital domain may affect the war in Eastern Europe at the margins, but it will not decide it. That should tell us something about the West’s cyber posture.

A Ukrainian security researcher this week leaked several years of internal chat logs and other sensitive data tied to Conti, an aggressive and ruthless Russian cybercrime group that focuses on deploying its ransomware to companies with more than $100 million…

A Ukrainian cyber guerrilla warfare group plans to launch digital sabotage attacks against critical Russian infrastructure such as railways and the electricity grid, to strike back at Moscow over its invasion, a hacker team coordinator told Reuters.

Meanwhile, the hackers behind the breach are now releasing some of the stolen files on the web.

Actions to Take Today: • Set antivirus and antimalware programs to conduct regular scans. • Enable strong spam filters to prevent phishing emails from reaching end users. • Filter network traffic. • Update software. • Require multifactor authentication. Leading up to Russia’s unprovoked attack against Ukraine, threat actors deployed destructive malware against organizations in Ukraine to destroy computer systems and render them inoperable.
