Microsoft released a record 622 CVEs in Patch Tuesday with live Active Directory and SharePoint zero-days, while Progress ShareFile confirmed active exploitation of a Storage Zone Controller vulnerability. CET callstack-spoofing techniques resurfaced with Valkyrie-bot kernel rootkit, GodDamn/PoisonX EDR-killing, and CVE-2024-21338 being weaponized by Lazarus Group, alongside 15-year-old kernel bugs like GhostLock and forgotten Secure Boot shims.

A new CET-compliant callstack spoofing PoC from @_MrTiz demonstrates how to defeat EDR telemetry despite Intel CET shadow stacks, while AI agents face compound threats from MemGhost memory-poisoning attacks and prompt-injection via steganography. xAI's Grok Build CLI inadvertently uploaded private Git repositories to Google Cloud, exposing AI dev tooling as a fresh supply-chain vector. The FBI and Google dismantled "Outsider," an $88-per-week phishing-as-a-service platform responsible for ~$1.9 billion in losses, and the US Treasury sanctioned 1VPNS and its administrator for enabling ransomware infrastructure targeting hospitals and schools.

Android 17 users face a public browser-to-kernel exploit chain combining Firefox JIT RCE (CVE-2026-10702) with kernel exploits for full device compromise. U-Boot firmware has six critical signature-verification flaws affecting 50+ stable releases and embedded devices worldwide, enabling arbitrary code execution and root-of-trust bypass. AI coding agents are now targets: Ghostcommit hides prompt-injection payloads in PNG images to steal environment secrets, while HalluSquatting weaponizes AI model hallucinations to register fake package names and deliver botnets to trusting developers. The jscrambler npm package was compromised with a Rust infostealer that executes on installation across Windows, macOS, and Linux.

GhostLock (CVE-2026-43499), a 15-year-old Linux kernel use-after-free in every mainstream distribution since 2011, enables unauthenticated root access and container escape when paired with a Firefox 0-day in a full browser-to-kernel exploit chain. GhostApproval symlink flaws in six AI coding assistants (Amazon Q Developer, Claude Code, Cursor, Google Antigravity, Windsurf, Augment) allow booby-trapped repositories to redirect file writes and achieve RCE via misleading confirmation dialogs. CISA added actively-exploited Adobe ColdFusion (CVE-2026-48282) and Langflow auth-bypass flaws to its KEV catalog, with the Langflow issue matching the JADEPUFFER operator's exploitation from the prior week. AI agents are lowering the barrier for less-skilled attackers: hallucination-squatting registers fake package names that models invent, delivering malware to developers, while researchers demonstrate that agents scanning untrusted code for bugs can instead execute the attacker's payload on the analyst's machine.

Synacktiv publicly disclosed a Kerberos reflection bypass (CVE-2026-26128) with working proof-of-concept code that grants SYSTEM privileges on most Windows builds, moving priority-escalation tactics into the open. GitHub Agentic Workflows fell victim to prompt injection attacks that leaked private repositories after attackers filed public issues with malicious payloads on open repos. BeyondTrust, Gitea, and Adobe ColdFusion all shipped critical pre-authentication remote-code-execution and authentication-bypass flaws now under active exploitation. Anthropic revealed that Claude contains hidden working memory ("J-Space") that shows the model recognizes eval scenarios before generating its first token, and researchers found covert telemetry embedded in Claude Code characterized by Anthropic as an abuse-prevention experiment.

A 16-year-old KVM hypervisor vulnerability (CVE-2026-53359) enabling guest-to-host escape is under public exploitation, with panic PoCs already available. Adobe ColdFusion CVE-2026-48282 (CVSS 10.0) is being actively exploited in the wild within hours of disclosure, with unauthenticated remote code execution possible. AI-powered coding agents are now a live attack surface, with researchers demonstrating agent hijacking, malicious skill injection, and data exfiltration through prompt injection in creator tools like YouTube's Ask Studio. Iran-linked hackers are deploying a new modular C2 framework called Cavern against Israeli targets, while ClickFix malware operators are leveraging blockchain as a resilient command infrastructure.

The Gentlemen ransomware crew exploited a zero-day in a signed Kontron driver to disable endpoint defenses via BYOVD, gaining kernel-level access to terminate security processes before deploying ransomware. CVE-2026-46242 (Bad Epoll) now has a public proof-of-concept for a Linux kernel use-after-free that enables privilege escalation on 6.4+ kernels with 99% reliability. Medtronic is notifying 3.8 million individuals after a ShinyHunters data breach exposed personal and medical data. Multiple new red-team tools and offensive-security frameworks including T3MP3ST, goshs, and Knossos were released, alongside DOJ filings revealing how Microsoft telemetry helped the FBI identify alleged Scattered Spider member Peter Stokes via Windows Global Device ID correlation.

Huntress detailed an LDAP Ping technique that enumerates Active Directory usernames without triggering Windows audit logs, enabling stealthy reconnaissance for password spraying attacks. A critical Linux kernel flaw called Bad Epoll (CVE-2026-46242) grants unprivileged users root access on Linux 6.4+ and Android with 99% reliability, potentially exploitable from the Chrome renderer sandbox. Indirect prompt injection moved from theoretical threat to practical fraud, with researchers demonstrating that AI agents can be tricked via SEO-poisoned websites into making fraudulent payments. Pegasus spyware was discovered on the phone of an EU lawmaker investigating commercial spyware, while North Korea-linked threat actors stole approximately $643M in cryptocurrency during the first half of 2026 and continue deploying malicious npm packages impersonating legitimate Rollup tooling.

watchTowr Labs disclosed CVE-2026-8451, a pre-auth memory overread in Citrix NetScaler SAML handling that extends the CitrixBleed lineage, alongside five other patched flaws. A China-linked USB implant infected Japanese military networks for nearly a year via disaster-relief supply chains, while European defense targets faced spear-phishing campaigns abusing AWS Cognito for credential-less C2 infrastructure. Multiple AI agent safety bypasses emerged, including GuardFall (shell injection against coding agents), BioShocking (prompt injection stealing credentials), and poisoned MCP tool descriptions enabling data exfiltration without raising alerts.
