Compromised by Design: Identity Gaps in Collaboration and Cloud
From collaboration tools to kernel vulnerabilities, this week’s stories reveal just how interconnected identity has become with every layer of your infrastructure. We’re tracking the latest threats and trends, from Teams token abuse and Azure storage exploits to evolving infostealers like Vidar 2.0 and overlooked risks like “job huggers” inside the workforce.
We also dive into the deeper infrastructure implications of recent Ubuntu and IPFire updates, because when your network and host layers aren’t secure, neither is your identity fabric.
Identity & Cybersecurity
Collaboration & Storage Breaches Highlight Identity Gaps
A new attack targeting Microsoft Teams access tokens shows just how easily attackers can hijack collaboration by abusing federated trust. These tokens are high-value secrets; treat them that way. Tighten conditional access, monitor session anomalies, and scrutinize consent flows.
Meanwhile, recent Microsoft threat intel reveals how attackers are chaining OAuth token theft, subscription keys, and exposed secrets to breach Azure Blob Storage. The key takeaway: identity is your control plane. Enforce least privilege, monitor token events, and block privilege escalation paths before storage becomes a launchpad for lateral movement.
Infostealers Evolve: Vidar 2.0 Steps Into the Void Left by Lumma Stealer
As Lumma Stealer’s influence fades, a new player is rising: Vidar 2.0. This infostealer has been fully rewritten in C and now features a multithreaded architecture, allowing it to operate faster and more stealthily. Vidar isn’t just going after passwords; it’s targeting everything from browser credentials and cloud service tokens to cryptocurrency wallets and gaming sessions. It even uses memory injection techniques to bypass security controls like Chrome’s AppBound. For identity and access management leaders, this trend is a clear signal: stolen tokens are more than data: they are keys to your entire environment. Kernel-Level Exposure: Ubuntu’s Use-After-Free Vulnerability A newly disclosed vulnerability in Ubuntu’s 24.04.2 kernel (version 6.8.0-60) exposes systems to local privilege escalation via a flaw in the af_unix socket subsystem. This use-after-free bug, caused by an incomplete upstream patch, can allow an attacker with local access to gain root privileges. While the issue is patched in version 6.8.0-61, the existence of proof-of-concept exploit code raises concern, especially in environments where IAM services or critical infrastructure run on affected Ubuntu versions. For identity-focused operations, the implications are clear: even the best access policies can be undermined if the host OS itself is compromised.
Policy & Industry Trends
When Loyalty Becomes a Security Risk
IT Brew warns about a rising threat: “job huggers”, employees clinging to roles in uncertain times, who unintentionally weaken your security posture.
Fatigue and familiarity at the service desk create perfect conditions for attackers to blend in. Don’t let social engineering look like business as usual. To prevent vulnerabilities, link identity changes to risk signals and use second-party verification for privileged actions, especially in regulated sectors.
IPFire 2.29 Raises the Bar for Network Defense
A major upgrade to IPFire, version 2.29 (Core Update 198), introduces substantial enhancements to its intrusion prevention system, reporting capabilities, and core security stack.
Key improvements include the integration of Suricata 8 for faster and more reliable threat detection, expanded protocol support (DNS‑over‑HTTP/2, WebSocket, SIP over TCP, etc.), and real‑time alerting with PDF reports and remote syslog forwarding to maintain audit trails even if the firewall is compromised. These upgrades make IPFire not just a firewall, but a more intelligent perimeter partner, capable of feeding high-fidelity signals into your broader identity and threat detection ecosystem.
This Week’s Mission
Whether it’s credential misuse, third-party exposure, or help desk fatigue, the threats may vary, but the solution remains consistent: make identity your control plane and automate enforcement across every layer of your stack.
As the ecosystem shifts, your defenses need to evolve just as fast.
