Welcome to this edition of the CyberPress weekly cybersecurity newsletter — your cybersecurity bulletin covering the 50 most important stories from August 10 to 14, 2026, organized day by day. Zero-days dominated the week: a Zoom zero-click flaw could take over devices, the ShieldBreak zero-day bypassed a Windows Defender patch, and Microsoft’s Patch Tuesday fixed 398 flaws including an exploited WinSock zero-day.
Attackers leaned hard on identity and AI — Pass-the-Passkey and GhostJacking bypassed modern defenses, the LiteLLM supply-chain breach spread through CI/CD, and Apple warned users of mercenary spyware.
Everything below is curated into one weekly cybersecurity newsletter so you can scan the week in minutes and click through to the full analysis.
FRIDAY · AUGUST 14, 2026
1 ATTACK Apple Warns iPhone Users of Government-Grade Mercenary Spyware Attacks

17 ATTACK Chrome Fingerprint Spoofing Makes Kimwolf HTTP/2 Floods Harder to Separate From Real Users
The Kimwolf DDoS tool spoofs Chrome fingerprints so its HTTP/2 floods blend in with legitimate traffic. The technique complicates mitigation because malicious requests look like real browsers.
18 MALWARE Gunra Targets Primary and Disaster-Recovery Backups Before File Encryption
The Gunra ransomware crew deliberately cripples primary and disaster-recovery backups before encrypting files. Destroying recovery options increases pressure on victims to pay.
19 ATTACK One Missing MFA Control Lets Credential Spray Become a Full Akira Ransomware Intrusion

21 VULN ShieldBreak Windows Defender Zero-Day Bypasses Microsoft Patch to Gain SYSTEM Access
The ShieldBreak zero-day sidesteps a Microsoft Defender patch to gain SYSTEM-level access on Windows. Bypassing the built-in defender that most organizations rely on is a serious escalation path.
22 PATCH Microsoft Patches 398 Windows Flaws Including an Actively Exploited WinSock Zero-Day
Microsoft’s Patch Tuesday fixed 398 Windows vulnerabilities, including a WinSock zero-day already under active exploitation. The sheer volume makes prompt, prioritized patching essential.
23 VULN CISA Warns of Actively Exploited Metabase Flaw Enabling Admin Account Takeover
CISA added an actively exploited Metabase flaw to its Known Exploited Vulnerabilities catalog after admin-takeover attacks. Analytics platforms often hold direct database access, raising the stakes.
24 VULN CopyEscape Docker Flaw Lets Malicious Containers Overwrite Host Files and Execute Code

36 AI New GhostJacking Attacks Hijack AI Agents to Bypass Firewalls and Steal Cloud Credentials
GhostJacking attacks hijack AI agents to slip past firewalls and steal cloud credentials. As agents gain real system access, they become a powerful new target for abuse.
37 MALWARE New C++ Abyssos RAT Gives Attackers Remote Shell, VNC and File-System Control
The new C++ Abyssos RAT hands attackers a remote shell, VNC access and full file-system control. Its broad capabilities make it a versatile tool for hands-on-keyboard intrusions.
38 ATTACK Pass-the-Passkey Attack Bypasses Phishing-Resistant MFA and Impersonates Privileged Users
A Pass-the-Passkey technique bypasses phishing-resistant MFA to impersonate privileged users. It challenges the assumption that passkeys alone make account takeover impossible.
39 MALWARE DeadLock Steals Corporate Data Before Encrypting Systems and Threatening Public Leaks
DeadLock ransomware exfiltrates corporate data before encryption, then threatens to publish it. The double-extortion model pressures victims even when they can restore from backups.
40 VULN ClamAV Memory Corruption Bugs Expose Cisco Secure Endpoint to Remote DoS Attacks
Memory-corruption bugs in ClamAV can be abused to knock over Cisco Secure Endpoint via remote denial of service. Flaws in scanning engines can turn a defensive tool into an availability risk.
MONDAY · AUGUST 10, 2026
