Apple Fixes Hide My Email Bug That Exposed Real Addresses in Mail Logs

Apple Fixes Hide My Email Bug That Exposed Real Addresses in Mail Logs

Jul 21, 2026 Vulnerability / Cloud Security
Apple has moved to address a security flaw in its Hide My Email service that enabled users' real email addresses to be unmasked, effectively undermining the feature's privacy guarantees. 404 Media reported Tuesday that a fix for the issue was deployed by Apple on July 3, 2026, after more than a year, when it was disclosed to the company by Tyler Murphy, co-founder of EasyOptOuts. Hide My Email generates unique, random email addresses that forward messages to a user's personal email inbox automatically. By creating disposable email addresses, the idea is to safeguard user privacy and tackle unwanted spam. The feature requires a paid subscription to iCloud+ and was announced by Apple in June 2021. However, at the start of the month, details emerged of a flaw that made it possible to unmask a user's real email address hidden behind a Hide My Email address. The issue was first reported to Apple on June 13, 2025, with Apple unsuccessfully attempting to patch it e...
AWS Kiro Flaw Let a Poisoned Web Page Rewrite Its Config and Run Code

AWS Kiro Flaw Let a Poisoned Web Page Rewrite Its Config and Run Code

Jul 21, 2026 AI Security / Vulnerability
Hidden text on a web page was enough to make Kiro , AWS's agentic coding IDE, rewrite its own configuration file and run an attacker's code on a developer's machine, with no approval step able to stop it. Intezer, in research with Kodem Security, found that a request as ordinary as asking Kiro to summarize a page could end in remote code execution. AWS has patched the issue, and no CVE has been assigned to it. Kiro's safety model rests on a human clicking "allow." The agent can run shell commands, fetch URLs, and edit files, and the design assumes a developer reviews anything risky before it happens. That approval step is the security boundary, and the flaw let an attacker slip past it without the developer ever being offered a choice. The weak point was the file that tells Kiro which external tools to load. Kiro reads its list of Model Context Protocol servers, and the exact command used to start each one, from ~/.kiro/settings/mcp.json. When that fi...
Google Launches Gemini 3.5 Flash Cyber AI to Find and Fix Software Vulnerabilities

Google Launches Gemini 3.5 Flash Cyber AI to Find and Fix Software Vulnerabilities

Jul 21, 2026 Software Security / Artificial Intelligence
Google's DeepMind on Tuesday announced the release of Gemini 3.5 Flash Cyber , a specialized artificial intelligence (AI) model built atop 3.5 Flash that's designed to discover, validate, and patch vulnerabilities quickly and efficiently. According to the tech giant, the model will be exclusively available to governments and trusted partners via CodeMender as part of a limited-access pilot program. CodeMender is an AI-powered agent for vulnerability discovery and patching that was unveiled by the company in October 2025. A Google DeepMind spokesperson told The Hacker News that there are plans to extend the model's capabilities to include red-teaming features and end-to-end enterprise defense. The lightweight model, per DeepMind, is both cost-efficient and highly capable alternative to large, costly cybersecurity-focused models. CodeMender can call upon 3.5 Flash Cyber "multiple times at high speed and low cost," allowing the AI agent to scan more code path...

Critical SharePoint RCE CVE-2026-50522 Under Active Exploitation After Public PoC

Critical SharePoint RCE CVE-2026-50522 Under Active Exploitation After Public PoC

Jul 21, 2026 Vulnerability / Web Security
A third SharePoint Server flaw patched by Microsoft as part of its Patch Tuesday update for July 2026 has come under active exploitation, per watchTowr . The vulnerability in question is CVE-2026-50522 (CVSS score: 9.8), a critical deserialization of untrusted data in Microsoft Office SharePoint that could allow an unauthorized attacker to execute code over a network. Microsoft credited DEVCORE researcher "splitline" with discovering and reporting the flaw. "In a network-based attack, an attacker authenticated as at least a Site Owner, could write arbitrary code to inject and execute code remotely on the SharePoint Server," Redmond said in an advisory released last week. "The attack vector is Network (AV:N) because this vulnerability is remotely exploitable and can be exploited from the internet. The attack complexity is Low (AC:L) because an attacker does not require significant prior knowledge of the system and can achieve repeatable success with the ...
Qilin Ransomware Attackers Exploit PAN-OS Authentication Bypass for Initial Access

Qilin Ransomware Attackers Exploit PAN-OS Authentication Bypass for Initial Access

Jul 21, 2026 Vulnerability / Network Security
Threat actors have been observed exploiting a now-patched high-severity Palo Alto Networks PAN-OS vulnerability as an entry point to deploy Qilin (aka Agenda) ransomware on victim environments. Arctic Wolf Labs said it investigated multiple intrusions in June 2026 that began with the exploitation of CVE-2026-0257 (CVSS score: 7.8), an authentication bypass flaw affecting the portal and gateway components of PAN-OS software. Successful exploitation of the flaw allows unauthenticated remote attackers to sidestep authentication and establish VPN sessions without valid credentials when authentication override cookies are enabled with specific certificate configurations. "Post-exploitation tradecraft varied across intrusions, from rapid encryption-only operations to full double-extortion, possibly suggesting multiple affiliates operating under the Qilin ransomware-as-a-service (RaaS) umbrella," the cybersecurity company said .
