What the Tech: Phone antivirus apps |Helpful protection or a scam?

Most individuals do not require antivirus apps on their smartphones, as the primary threats have shifted from traditional viruses to scams and deceptive practices. iPhones utilize app isolation, making them less susceptible to conventional viruses but vulnerable to scams like phishing and fraudulent messages. Android phones allow sideloading, increasing the risk of malware from unofficial sources. The main threats include phishing texts, fake login pages, scam calls, reused passwords, and social engineering tactics. To enhance security, users should keep their phones updated, use strong passwords, enable two-factor authentication, avoid suspicious links, and refrain from installing apps from unknown sources. Antivirus apps may be helpful in specific situations, such as frequent link tapping or downloading files from unfamiliar websites, with reputable companies offering mobile security solutions focused on scam detection and account safety.

What the Tech? Antivirus protection for your smartphone

Most users do not require an antivirus app on their smartphones, as the predominant threats are scams such as phishing texts and fraudulent websites rather than traditional viruses. iPhones operate on a design that isolates apps, limiting the effectiveness of antivirus software, while Android devices allow sideloading, which can increase the risk of malware. The real danger lies in deception tactics used by cybercriminals, making personal account security more important than antivirus software. To enhance security, users should keep their operating systems updated, use strong passwords, enable two-factor authentication, avoid suspicious links, and refrain from installing apps from unknown sources. Antivirus apps may be beneficial for users who frequently click on unverified links, download files from unfamiliar sites, or engage in Android sideloading. Reputable security apps focus on scam detection and web protection rather than traditional virus scanning.

Tired of fake smartphone photos? This Android camera app might be the fix

VWFNDR has launched a new camera app called VWFNDR + MBL, which captures unprocessed Bayer RAW DNG and JPEG files, avoiding modern computational photography. The app supports various aspect ratios and offers manual controls for ISO, shutter speed, focus, and exposure compensation. Each photo includes a tamper-evident record via the open Content Credentials standard from C2PA, verifying the image's source and integrity. VWFNDR is the fourth company globally to achieve C2PA Level 2 conformance and the second to support it for DNG files. The app is currently free for Android 10 or later devices but only supports the primary rear camera.

MSHTA abuse helps malware hide in Windows processes

Bitdefender's research highlights the use of Microsoft's MSHTA utility in malware attacks, noting its default activation in Windows systems. Cybercriminals exploit MSHTA to execute malicious scripts under the guise of legitimate processes, linking it to various malware families like LummaStealer and PurpleFox. The study reports a rise in MSHTA-related detections, indicating a shift towards "living-off-the-land" tactics that utilize legitimate tools to evade security alerts. Social engineering is identified as a common entry point for attacks, employing deceptive methods such as fake software downloads and phishing links. MSHTA can retrieve and execute additional payloads through multi-stage chains, complicating detection efforts. The attacks target sensitive information, including credentials and financial data, and the continued presence of MSHTA poses risks as it allows threat actors to conceal malicious actions. To mitigate these threats, organizations are advised to restrict or disable legacy scripting tools and exercise caution with untrusted downloads. The report emphasizes the challenge of detecting unusual behaviors associated with legitimate utilities in the context of cyber threats.

PoC Released for 20-Year Old PostgreSQL RCE Flaw

A public proof-of-concept exploit has been released for CVE-2026-2005, a critical heap-based buffer overflow vulnerability in PostgreSQL's pgcrypto extension, allowing full remote code execution and privilege escalation to the database superuser level. This vulnerability has existed since 2005 and was discovered by an AI-powered security tool during the ZeroDay.Cloud 2025 event in December 2025. An upstream patch was committed on February 8, 2026, and released on February 12, 2026. The vulnerability has a CVSS score of 8.8 and affects approximately 80% of cloud environments using PostgreSQL, with 45% accessible via the internet. The flaw is in the pgp_parse_pubenc_sesskey() function, which lacks bounds checking, allowing attackers to manipulate session key lengths. The pgcrypto extension can be installed by any database role with CREATE privileges, increasing the risk of exploitation. The proof-of-concept exploit involves an information leak, arbitrary write, and privilege escalation to remote code execution. The vulnerability affects all major versions of PostgreSQL prior to the February 2026 releases, which include versions 18.2, 17.8, 16.12, 15.16, and 14.21. Mitigation steps include upgrading to patched versions, restricting CREATE privileges, blocking direct internet exposure, rotating database credentials, auditing the usage of COPY FROM PROGRAM, and verifying patched engine versions for cloud-managed PostgreSQL users.

Critical PostgreSQL Vulnerabilities Enables Code Execution and SQL Injections

The PostgreSQL Global Development Group has released security updates for versions 18.4, 17.10, 16.14, 15.18, and 14.23, addressing 11 vulnerabilities, including critical issues related to arbitrary code execution and SQL injection flaws. All supported branches from 14 through 18 are affected by vulnerabilities, necessitating updates. Database administrators can perform in-place upgrades without needing a dump/restore. Key vulnerabilities include: - CVE-2026-6637: Stack buffer overflow in the refint module allowing arbitrary code execution. - CVE-2026-6472: Privilege bypass and arbitrary SQL execution. - CVE-2026-6473: Potential remote code execution and memory corruption. - CVE-2026-6474: Server memory information leak. - CVE-2026-6475: Arbitrary file overwrite vulnerability. - CVE-2026-6476: SQL injection with superuser execution. - CVE-2026-6477: Client-side code execution risk. - CVE-2026-6478: MD5 credential timing leak. - CVE-2026-6479: SSL/GSS denial-of-service flaw. - CVE-2026-6575: Limited memory disclosure issue. - CVE-2026-6638: SQL injection in logical replication. Organizations using PostgreSQL 14 should upgrade to version 14.23 and plan migration to a newer version before the end-of-life on November 12, 2026. The updates are urgent for deployments exposed to the internet or in multi-tenant environments.

“I thought it was a Steam game”… Malicious code found planted on users’ PCs

'Beyond the Dark' is an indie game released for free on Steam on December 29, 2024, which was misrepresented as a turn-based strategy game despite displaying characteristics of a first-person horror game. Tech YouTuber Eric Parker identified it as an 'asset flip' and revealed that it distributed malware designed to steal cryptocurrency wallet information and Roblox account credentials. The malware was embedded in a DLL file activated upon the game's execution. Following Parker's findings, Valve removed the game from its platform within a day. The gaming community has seen similar incidents, such as the 'Blockbusters' game in September 2025, which was involved in a malware scheme that stole cryptocurrency. Security experts advise caution when installing free games that appear hastily produced.

Google Messages’ easiest pairing method is about to disappear

The QR code pairing method for accessing the Google Messages desktop web app is being phased out, as indicated by the removal of the QR code scanner option in the latest beta version, v20260511. Users will soon need to link their devices and access the web app using their Google account credentials instead. Although the QR code option is still available in the web app for now, Google is preparing to eliminate it entirely. Users are encouraged to familiarize themselves with the Google account sign-in process, as adaptation to the new login method will be necessary in the near future.
