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.

Dans un exercice d'équilibriste, l'Anssi a demandé aux entreprises de s'interroger sur l'utilisation des solutions de l'éditeur Kaspersky du fait des liens avec la Russie. Elle prône à moyen terme une diversification des outils de sécurité.

Les tensions internationales actuelles causées par l’invasion de l’Ukraine par la Russie s’accompagnent d’effets dans le cyberespace. Si les combats en Ukraine sont principalement conventionnels, l’ANSSI constate l’usage de cyberattaques dans le cadre du conflit. Dans un espace numérique sans frontières, ces cyberattaques peuvent affecter des entités françaises et il convient sans céder à la panique de l’anticiper et de s’y préparer. Aussi, afin de réduire au maximum la probabilité de tels événements et d’en limiter les effets, l’ANSSI partage des bonnes pratiques de sécurité ainsi que des éléments sur la menace et invite l’ensemble des acteurs à s’en saisir. A cette fin, ce bulletin centralise et diffuse les éléments d’intérêt cyber en lien avec le contexte actuel pour favoriser le renforcement du niveau de protection de l’ensemble des entités françaises. Il sera mis à jour régulièrement.

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.
