Guidance is circulating on how to check whether your email address or password has been exposed in a data breach, directing users to breach-notification lookup services such as Have I Been Pwned. Security writers recommend checking old passwords, changing any that appear in breach databases, and enabling two-factor authentication. The renewed interest follows a steady drumbeat of large credential leaks affecting major online services, leaving many users unsure which of their accounts may be compromised.

PC World examines what happens when an AI agent is granted access to a user's Gmail account, weighing both the benefits and the risks. The piece argues that unease about letting AI read and act on personal email is justified, but offers guidance on settings that limit what the AI can see and do for those who still want the convenience.

A question posted on Hacker News asks whether traveling abroad can lead to email leakage, drawing attention from the tech community. The discussion stems from a user's concern about the security of their email when crossing borders or using foreign networks. Commenters are weighing in on how email data may be exposed through different infrastructure, surveillance, or unsecured connections while overseas.

Users of Grok are rushing to claim custom email addresses under the mail.grokbot.com domain, turning address sign-ups into a competitive grab for desirable handles. Early adopters are posting about securing short or personalized names before they are taken, and the scramble is driving wide discussion about how long the free sign-up window will stay open and what the service offers.

Reports claim the Samsung Galaxy S26 has been hacked through a simple email vulnerability. According to the headline, attackers could compromise the device via a flaw tied to email handling. Few details are available about how the attack works, who carried it out, or whether Samsung has responded, so the scope and severity of the alleged security flaw remain uncertain.

OpenAI reportedly used AI to help draft an email warning the Australian government that hackers, also using AI, had targeted and breached its websites. The episode highlights how artificial intelligence is now involved on both sides of cyberattacks and in responses to them, drawing attention to the growing security risks governments face from AI-enabled intrusions.

Email security is being reshaped as attackers use generative AI to craft more convincing phishing and social engineering, while defenders deploy AI-driven tools to detect and block them. A new Register sponsored feature outlines this 'old attack, new protections' landscape, arguing that traditional filters are no longer enough and that generative AI must now be met with generative AI defenses.

Apple plans to strengthen Full Disk Access controls on macOS to prevent AI agents from freely reading files, emails, messages and browsing history. Reports describe the move not as a new restriction, but as introducing clearer, more explicit user consent, aimed at reducing privacy and security risks as AI tools increasingly operate directly on people's computers.

Jacob Aaron Hicks, an Arizona man, was arrested after allegedly emailing a Tucson news station a threat claiming an imminent bomb strike against the White House. The message prompted an FBI investigation leading to his arrest. Authorities have not detailed a motive, and the case adds to a string of recent threats against federal buildings and officials.

The FBI, NSA and CISA issued an alert on Chinese hackers linked to Integrity Technology Group, who are actively stealing emails from government and critical infrastructure organizations worldwide. The advisory highlights ongoing state-backed cyber espionage, and comes amid heightened geopolitical tension, with the US reportedly weighing potential renewed military strikes against Iran.

Security researcher Jake Low has disclosed several now-fixed vulnerabilities in the backend of MapRoulette, the OpenStreetMap mapping challenge platform. According to the disclosure, the flaws may have exposed access credentials — though not passwords — and user email addresses to attackers. The issues have since been patched, and the disclosure is drawing attention within the OpenStreetMap and open-source mapping communities.

A cybersecurity commentator has highlighted a common corporate security gap: employees who leave a company on Friday often still have active accounts and email access on their devices by Monday. The post points to the UK's NCSC guidance on joiners, movers and leavers processes, arguing that while leavers are often overlooked, internal job movers are the most neglected group, with old access rights quietly lingering.

A new guide explains how to set up an email address on your own domain, arguing that a custom address gives you a lasting identity independent of any provider. It also makes the case that most people do not need to host their own mail server, since managed services can handle delivery, security and maintenance. The piece is being shared in privacy and open-source focused information security circles.

Hoxhunt has introduced Respond, a security tool that automates the triage of reported phishing emails and removes malicious messages from user inboxes. The product aims to cut the time security teams spend handling human-reported threats. Coverage of the launch is drawing attention from cybersecurity professionals interested in AI-driven email defence.

Security firm Huntress reports a phishing campaign in which attackers abuse legitimate Microsoft Power BI domains to bypass email security filters and trick users into installing rogue ScreenConnect remote monitoring and management clients. Because the malicious links come from trusted Microsoft infrastructure, they evade common detection methods. Cybersecurity researchers are warning organizations to scrutinize Power BI sharing invitations and monitor for unauthorized ScreenConnect installations.

Microsoft has added .msix and .msixbundle files to the list of file types Outlook blocks from being sent as email attachments. The change targets Windows app package formats that attackers can abuse to deliver malware, adding to a long list of restricted extensions. Reactions are largely sarcastic, with users joking that few people were sending such files anyway, while security-minded observers welcome the tightening of email protections.

Security researchers at Rapid7 have detailed a new variant of the BPFDoor backdoor and a related implant called AVERAT that operate on Linux-based telecom network edge devices. The malware disguises its command traffic as ordinary email, making it hard to detect, and is linked to an operations-relay infrastructure. Researchers have published guidance on how organisations can hunt for infections.

Cybersecurity researchers are warning about a phishing site at webmail-kawartha-inbox.weebly.com, which mimics a webmail login page, apparently targeting Kawartha users to steal email credentials.
