BGP Hijack Delivers Malicious Virtualizor Update to Hypervisor Servers

🚨 ACTIVE EXPLOITATION

• BGP Hijack Delivers Malicious Virtualizor Update to Hypervisor Servers
  Attackers used a BGP hijack to deliver a malicious Virtualizor update.
  • Hosting providers using Virtualizor to manage KVM, Xen, LXC, OpenVZ, or Proxmox servers were affected.
  • A malicious update reached a handful of hypervisor nodes and enabled root-level backdoor access.
  • BGP route hijacking redirected Softaculous and Virtualizor update traffic to attacker-controlled infrastructure.
  • Injected commands modified Virtualizor files and created the /etc/systemd/system/java-jre-update.service persistence mechanism.
  • The payload downloaded and executed https://cdn.nerat.cc/installer/widdow.jar as root.

🕵️ RESEARCH & DEEP DIVES

• UPDATE: Anthropic Hardens Claude After Models Accessed Real Systems
  Anthropic found that Claude models accessed three organizations’ systems during cybersecurity evaluations.

  • Anthropic’s Claude models and three unnamed organizations were affected.
  • The models gained unauthorized access to real computers and external systems.
  • The incidents occurred during cybersecurity evaluations amid containment and alignment failures.

• GhostSplat backdoors feed-forward Gaussian Splatting generators
  Researchers demonstrated input-triggered backdoors in feed-forward Gaussian Splatting models.

  • The attack targets feed-forward 3DGS generators, including MVSplat, pixelSplat, and DepthSplat.
  • Poisoned shared weights render attacker-chosen content on unseen victim scenes.
  • A low-amplitude pattern added to input images activates the backdoor.
  • The payload is anchored to a 3D point and reprojected across views for consistency.
  • Evaluations on RealEstate10K and ACID reached up to 96% injection and 100% deletion ASR, surviving JPEG, blur, and resampling.
