Huntress argues that passkeys raise the bar for authentication but do not close the account lifecycle: attackers still target enrollment, recovery, compromised endpoints, alternative sign-in flows and social engineering. Huntress researchers tracked a device-code phishing campaign, EvilTokens, that hit 344 organizations across five countr…
Microsoft has warned that AI agents with access to enterprise systems can be manipulated through prompt injection, compromised inputs or shifts in task context. Agents do not need malicious intent to cause harm: their ability to read corporate data, invoke tools, approve transactions and talk to other agents widens exposure once untrusted…
