Hackers Used AI to Build First Known Zero-Day 2FA Bypass, Google Warns

Google’s threat hunters have flagged a troubling milestone: the first known instance of a zero-day exploit likely discovered and weaponized using an artificial intelligence model. What began as an obscure Python script has been linked to a coordinated effort by cybercriminals to develop a two-factor authentication (2FA) bypass that could be scaled for mass exploitation. The disclosure underscores how AI

Breaking the code: how a multi-stage “code of conduct” phishing campaign led to AiTM token compromise

Breaking the code: how a multi-stage “code of conduct” phishing campaign led to AiTM token compromise

Phishing has evolved from crude scams to carefully engineered deceptions that mimic trusted internal processes. In mid‑April 2026, Microsoft Defender Research observed a large, multi‑stage campaign that did exactly that: it masqueraded as internal “code of conduct” notifications, used polished templates and legitimate delivery services, and funneled victims through a sequence of CAPTCHA and staging pages that ultimately proxied real

Critical Microsoft 365 Copilot Flaws: What Organizations Need to Know

Critical Microsoft 365 Copilot Flaws: What Organizations Need to Know

Microsoft has disclosed and silently remediated three critical information-disclosure vulnerabilities in Microsoft 365 Copilot and Copilot Chat in Microsoft Edge. The flaws—CVE-2026-26129, CVE-2026-26164, and CVE-2026-33111—were published on May 7, 2026, and Microsoft reports that mitigations were deployed on the cloud side so that no customer action or patch installation is required. While that immediate remediation reduces near-term risk, the underlying

How Mozilla Used Mythos to Find 271 Firefox Vulnerabilities — and What It Means

Mozilla says it used Anthropic’s Mythos model, together with a custom agent harness, to uncover 271 security issues in Firefox over roughly two months. The disclosure, supported by a small set of public Bugzilla reports, highlights a workflow that pairs large language models with deterministic tooling and verification to reduce hallucinations and produce actionable test cases — but it has

Critical Palo Alto Firewall Flaw: CVE-2026-0300 Exploited to Gain Root Access

Critical Palo Alto Firewall Flaw: CVE-2026-0300 Exploited to Gain Root Access

Palo Alto Networks has disclosed a critical buffer overflow vulnerability in PAN-OS that is already being exploited in the wild. The flaw, tracked as CVE-2026-0300, can allow unauthenticated attackers to run arbitrary code with full root privileges on affected PA-Series and VM-Series firewalls when the User-ID™ Authentication Portal (captive portal) is exposed to untrusted networks. Given the ease of exploitation

Copy Fail (CVE-2026-31431): A 4‑Byte Kernel Bug That Lets Attackers Gain Root on Major Linux Distros

Copy Fail (CVE-2026-31431): A 4‑Byte Kernel Bug That Lets Attackers Gain Root on Major Linux Distros

Microsoft Defender Security Research recently disclosed CVE-2026-31431—nicknamed “Copy Fail”—a high‑severity local privilege escalation in the Linux kernel’s crypto subsystem that enables an unprivileged user to escalate to root. The vulnerability affects kernels released since 2017 and has broad implications for cloud and container environments because the exploit can corrupt in-memory representations of readable files (including setuid binaries) without changing the
