Insikt Group identified 60 high-impact vulnerabilities in June 2026 (a 49% increase from May), with 23 listed in CISA's KEV catalog and 53 having public PoC exploits. The dominant theme was exploitation of externally reachable enterprise applications and appliances by multiple threat actors: StrikeShark chained 13 CVEs to deploy SharkLoader and Cobalt Strike, Lazarus exploited CVE-2025-55182 (React2Shell, CVSS 10.0) to deploy COPPERHEDGE and EtherRAT, APT36 targeted India via Microsoft Office/Windows CVEs, and Qilin ransomware was linked to Check Point gateway exploitation. 25 of the 60 vulnerabilities enabled RCE across 18 vendors, with CWE-22 (Path Traversal) being the most common flaw class.

Legitimate Tools Hijacked as AI Becomes the New Battleground The most damaging intrusions this week didn't rely on custom malware — they hijacked the legitimate tools and protocols organizations already trust. FortiBleed harvested real credentials from FortiGate firewall configurations worldwide, EvilTokens bypassed multi-factor authentication by abusing Microsoft's own device login flow, and a WhatsApp campaign installed legitimate ManageEngine remote management software to maintain persistent access. Simultaneously, attackers are learning to manipulate the AI systems defenders increasingly depend on. The macOS.Gaslight malware feeds fake error messages to AI analysis tools to blind security analysts, malicious skills on the OpenClaw marketplace trick AI assistants into executing harmful commands, and researchers demonstrated that chatbot reconnaissance can map an organization's defenses through casual conversation. Reset all FortiGate and VPN credentials immediately, scrutinize AI marketplace add-ons before installation, and assume that any legitimate-looking login prompt or remote management tool could be an attacker wearing a trusted disguise.

The StrikeShark campaign utilizes a novel malware family named SharkLoader to deploy Cobalt Strike Beacons across various global sectors. Threat actors gain initial access by exploiting known vulnerabilities in public-facing applications or distributing custom droppers disguised as legitimate software. SharkLoader employs advanced evasion techniques, including Perfect DLL Hijacking and extensive API hooking, to bypass loader locks and conceal its execution in memory.
