Critical Canon MailSuite Vulnerability Actively Exploited in the Wild

Image
When Enterprise Mail Security Becomes the Attack Surface As an independent cybersecurity blogger and part time penetration tester, email security gateways are often deployed specifically to protect organizations from cyberattacks. That is exactly why the newly disclosed Canon GUARDIANWALL MailSuite vulnerability is so concerning. Researchers and Japanese security authorities confirmed that attackers are already exploiting a critical stack based buffer overflow vulnerability that allows unauthenticated remote code execution against vulnerable Canon mail security infrastructure. The flaw, tracked as CVE-2026-32661 , carries: CVSS v3 score: 9.8 Critical Network based exploitation No authentication required Arbitrary code execution potential Because MailSuite products frequently sit directly in front of enterprise email infrastructure, the implications are severe. What Happened: Canon Disclosed an Actively Exploited RCE Vulnerability Canon Marketing Japan and JPCERT/CC...

Critical Windows DNS Client Vulnerability Enables Credential Theft and Relay Attacks

Image
When DNS Requests Become a Path to Enterprise Compromise As an independent cybersecurity blogger and part time penetration tester, DNS traffic is often treated as background noise inside enterprise environments. That assumption is becoming increasingly dangerous. Researchers recently disclosed a serious Windows DNS client related vulnerability involving Kerberos relay abuse through manipulated DNS CNAME responses. The flaw enables attackers to redirect authentication requests toward attacker controlled systems and potentially compromise enterprise environments even when NTLM is disabled. The attack targets one of the most trusted processes inside Windows environments: DNS resolution Kerberos authentication Service Principal Name handling Enterprise trust relationships Because DNS sits at the core of nearly every Windows network interaction, the implications are severe. What Happened: Researchers Revealed DNS Based Kerberos Relay Abuse Security researchers disclosed a...

PoC Exploit for Android Zero Click Vulnerability Raises Alarm

Image
When a Wireless Signal Becomes an Attack Vector: Inside the Android Zero Click Exploit As an independent cybersecurity blogger and part time penetration tester, few vulnerabilities create as much concern in the security community as true zero click exploits. Why? Because victims do not need to: Open a message Click a link Install an application Approve a prompt The attack simply happens. The latest Android zero click vulnerability involving CVE-2026-0073 has become even more concerning after researchers published proof of concept exploit code demonstrating how attackers could gain remote shell access against vulnerable devices. This is exactly the type of vulnerability advanced threat actors actively search for. What Happened: Researchers Released PoC Code for Android Zero Click RCE Researchers published proof of concept exploit tooling for CVE-2026-0073 , a critical Android zero click remote code execution vulnerability affecting modern Android devices. The flaw ...

Hackers Use PlugX Like DLL Sideloading Chain to Evade Detection

Image
When Trusted Applications Become Malware Launchers: Inside the PlugX Style DLL Sideloading Campaign As an independent cybersecurity blogger and part time penetration tester, some of the most effective malware campaigns today rely on a surprisingly simple concept: Do not look malicious. Instead of exploiting victims with obviously suspicious binaries, attackers increasingly abuse: Signed applications Trusted software Legitimate installers Familiar processes The latest PlugX style DLL sideloading campaign demonstrates exactly how modern attackers hide malicious activity inside software organizations already trust. And that makes detection significantly harder. What Happened: Researchers Identified a PlugX Like DLL Sideloading Chain Researchers uncovered a sophisticated malware campaign using a PlugX style DLL sideloading technique to establish stealthy persistence and remote access on victim systems. The attack chain reportedly involved: Legitimately signed executa...
