The keyv/cacheable npm worm changes the order of containment
What happened
Treat a match as a potential credential and publishing-identity compromise, not merely a dependency problem. The payload can execute through installation or repository-opening hooks, establish host persistence and trigger an attacker-controlled command when a stolen GitHub token is revoked.
The leadership decision
Security leaders should isolate matched developer endpoints and CI runners without powering them off. Declare a scoped supply-chain incident when an affected package version, execution artefact or persistence mechanism is found. The first authorised step should be network isolation without shutdown, preserving volatile evidence and preventing further exfiltration while avoiding the HTTP response that activates the watcher.
Vishing extortion shifts the control problem to personal phones and SaaS sessions
What happened
UNC6671 callers use urgent passkey or MFA-enrolment pretexts on employees’ personal phones, directing targets to adversary-in-the-middle portals. Successful sessions support automated SaaS data access, password resets for non-SSO applications and deletion of security notifications. The published infrastructure examples include passkeyhelpdesk[.]com, portalpasskey[.]com and addssopasskey[.]com.
The leadership decision
Security leaders should warn targeted staff that helpdesk teams do not conduct passkey enrolment through unsolicited personal calls. Move this campaign from the awareness queue into identity incident readiness. Identity owners should verify that phishing-resistant authentication applies to privileged and high-value SaaS applications, including enrolment, recovery and step-up flows.
Atuin can preserve Linux shell evidence that standard history collection misses
What happened
Linux incident playbooks that collect only .bash_history or .zsh_history can miss richer Atuin evidence. The database records command context and can retain soft-deleted or write-ahead-log artefacts, but synchronised entries may originate on another host. SANS ISC published the Atuin forensic note on August 7, 2026.
The leadership decision
Security leaders should add Atuin artefact discovery to Linux triage procedures. Direct incident response and endpoint engineering to add Atuin discovery to Linux acquisition profiles. Collection should include the database, write-ahead log, shared-memory file, encryption key, server-session token and configuration before interactive examination.
Self-evolving agent skills create a trajectory-poisoning control gap
What happened
The research demonstrates a control problem in agents that learn reusable skills from stored trajectories: apparently successful experience can become a poisoned instruction source. New controlled research shows how attacker-supported operating trajectories can be converted into persistent agent skills, challenging trust in retained experience and automated self-improvement.
The leadership decision
Security leaders should inventory agents that retain trajectories or generate reusable skills. Require an inventory of agents that retain trajectories, generate skills, fine-tune behaviour from operational history or import third-party skills. Production promotion should be blocked unless provenance and approval are recorded.
Automated SSH actors can move from valid login to persistence in 22 seconds
What happened
A single Cowrie sensor observed scripted post-authentication behaviour completing in seconds after a weak root password succeeded. SANS ISC honeypot telemetry documents an automated sequence that added an SSH key, changed the root password and weakened host controls before human response was possible.
The leadership decision
Security leaders should identify every internet-accessible SSH service and accountable owner. Require infrastructure owners to reconcile external attack-surface data with SSH daemon configuration and identity policy. Direct administrative exposure should be removed behind a bastion, VPN or zero-trust access broker.
