Android mental health apps with 14.7M installs filled with security flaws

Recent analysis by Oversecured identified 1,575 security vulnerabilities across ten mental health mobile applications, which include 54 high-severity, 538 medium-severity, and 983 low-severity issues. These apps, with over 14.7 million downloads, assist users with conditions like clinical depression and anxiety. Vulnerabilities include improper handling of user-supplied URIs, weak local data storage practices, and cryptographically weak session token generation. Six of the ten apps had no high-severity vulnerabilities, but medium-severity issues still pose risks to user privacy. The scans were conducted between January 22 and 23, 2026, and only four apps had received recent updates.

Unsecured AI apps are leaking personal data of Android users

Many unregulated or inadequately secured AI applications on platforms like the Google Play store pose significant privacy risks to users. A specific Android application, "Video AI Art Generator & Maker," linked to a data leak, compromised 1.5 million user images, over 385,000 videos, and millions of AI-generated media files due to a misconfiguration in a Google Cloud Storage bucket. Another app, IDMerit, exposed sensitive know-your-customer data from users in 25 countries, including full names, addresses, birthdates, IDs, and contact information, totaling a terabyte of data. Both developers addressed the vulnerabilities after being alerted by researchers. However, cybersecurity experts warn that lax security among AI applications is a widespread issue, with 72 percent of analyzed Google Play apps exhibiting security flaws, including the practice of "hardcoding secrets" in their source code.

Microsoft Fixes Critical Windows 11 Notepad Flaw

Microsoft has released a patch for a significant vulnerability in Notepad on Windows 11 that could allow attackers to execute code by opening a Markdown file and clicking on a malicious link. This vulnerability was due to how Notepad processed links within Markdown files, which could trigger unverified protocols to load remote content. The patch now includes a security warning before such links can be activated. Users are advised to check for updates via Windows Update and the Microsoft Store to ensure Notepad and related components are up to date. Security tips include inspecting URLs before clicking and keeping Microsoft Defender features enabled.

Using Windows 10? Do This Now to Lower Your Risk of Being Hacked

Support for Windows 10 officially ended last year, and Microsoft recommends users transition to Windows 11 or buy new computers. Users will no longer receive security updates, and any issues encountered will not be supported by Microsoft. Windows Update will indicate that devices are no longer receiving updates, leaving users to manage security vulnerabilities themselves. Microsoft Defender Antivirus will continue to receive updates until October 2028, and users can enroll in Extended Security Updates (ESU) for an additional year of security updates until October 13, 2026, under certain conditions. Windows 11 installations surpassed Windows 10 in June 2025, with Windows 11 at 53.7% and Windows 10 at 42.7%. Users opting to stay on Windows 10 should implement third-party security solutions to mitigate risks from the lack of official updates.
