Sansec warns the exploit method is already circulating and urges admins to restrict access to pub/media/custom_options/, verify nginx/Apache rules, and scan for uploaded shells or backdoors.

🧛 Cisco Talos highlights a growing trend in 2025: attackers increasingly seek to be authorised as legitimate users rather than relying solely on loud exploits. Telemetry shows nearly a third of MFA spray attacks targeted IAM applications and fraudulent device registrations surged 178%, indicating adversaries focus on the mechanisms that grant access. Talos urges organisations to harden authentication, prioritise patching, manage EOS/EOL devices, and adopt phishing-resistant controls as part of a broader defensive posture.

🔒 Many organizations invest heavily in login protections but leave password reset paths less scrutinized, creating an easy escalation route once attackers gain a foothold. The article explains common abuse scenarios — from helpdesk social engineering and intercepted reset tokens to misuse by over-permissioned admins — and recommends seven practical mitigations, including MFA, device posture checks, strict password policies, and avoiding knowledge-based authentication. It also highlights Specops tools to harden reset workflows and block breached passwords.

🔒 Multiple vulnerabilities in IGL-Technologies eParking.fi allow unauthenticated actors to connect to OCPP WebSocket endpoints, impersonate charging stations, issue commands, hijack sessions, or disrupt charging services via denial-of-service.

Other flaws enable brute-force attempts, session hijacking, and exposure of station identifiers. CTEK plans to sunset Chargeportal in April 2026; operators should restrict network exposure, isolate control networks, and contact CTEK support for guidance.

🤖 A user attempting to remotely control his own DJI Romo robot vacuum inadvertently gained control of approximately 7,000 devices around the world. The incident highlights how insecure many consumer IoT devices remain and how a single action can cascade into widespread exposure. Beyond mere nuisance, such mass control raises privacy and safety concerns if exploited at scale. The episode underscores the urgent need for stronger device authentication, secure update mechanisms, and clearer vendor responsibility.

🔒 Eclypsium researchers disclosed nine vulnerabilities in low-cost IP KVM devices from GL-iNet, Angeet/Yeeso, Sipeed, and JetKVM. The most severe flaws can allow unauthenticated attackers to gain root or execute arbitrary code and operate at BIOS/UEFI levels, enabling keystroke injection, booting from removable media, and persistence beyond OS defenses. Some vendors have issued firmware fixes, but critical issues in Angeet ES3 remain unpatched. Administrators should apply available updates, isolate KVMs, and enforce stronger access controls.

🔐 By 2026, the central competition in identity-related work will be the ability to prove that the person behind a high-impact action is a real, accountable human. Generative AI and deepfakes create synthetic identities that can pass routine checks, contaminate risk models and hijack estate workflows. Defenses must focus on provenance, cross-channel consistency and continuous, risk-based verification tied to audit-grade trails.

🔒 Apple has issued Background Security Improvements to address CVE-2026-20643, a cross-origin flaw in WebKit's Navigation API that could be exploited to bypass the same-origin policy when processing maliciously crafted web content.

🚨 A critical out-of-bounds write in the LINEMODE Set Local Characters (SLC) suboption handler of GNU InetUtils telnetd (CVE-2026-32746) enables unauthenticated remote attackers to achieve remote code execution as root. Discovered by Dream on March 11, 2026, the flaw affects releases through 2.7 and carries a CVSS score of 9.8. Exploitation can succeed during the initial Telnet handshake with a single connection to port 23; no credentials or user interaction are required. A patch is expected by April 1, 2026; until then, disable Telnet, avoid running telnetd as root, and block port 23.

🔒 CloudSEK researchers have identified an Android OS-level attack that manipulates the runtime via LSPosed modules to hijack legitimate payment apps without modifying APKs or invalidating app signatures. The campaign, associated with a module dubbed Digital Lutera, intercepts SMS, spoofs device identities, and captures 2FA in real time, effectively bypassing protections like Google Play Protect and persistent integrity checks. Reinstalling apps does not remove the malicious hooks, making detection and remediation difficult.

🛑 The UK’s Companies House has suspended its WebFiling dashboard after researchers Dan Neidle and John Hewitt revealed a simple flaw that allows an authenticated user to view another company’s dashboard by selecting “file for another company” and using the browser back button to bypass an authentication code.
