It’s time to stop believing these lies about antivirus software

The proliferation of social media misinformation, deep fakes, and sophisticated phishing attacks has made online safety challenging. Many individuals hold outdated beliefs about cybersecurity, such as the myth that Macs are immune to viruses and that caution alone can replace antivirus software. Regardless of the operating system, using a robust antivirus program is recommended, as built-in security features are not foolproof. Third-party antivirus software can provide additional functionalities like parental controls and VPN services, but they are not a complete safety net. Users must remain vigilant and practice good cybersecurity hygiene, including regular scans, strong passwords, and recognizing phishing attempts. Modern antivirus programs have become more user-friendly and less resource-intensive. Some malware can operate stealthily, making detection difficult, which emphasizes the need for regular scans and monitoring personal accounts for unusual activity. Antivirus protection should extend to mobile devices as well, as they are also vulnerable to cyber threats. Users should check if their antivirus program covers mobile devices and familiarize themselves with security settings on their smartphones.

Microsoft Data Loss Prevention (DLP): Tips to Protect Your Business Following the Latest Outage

Microsoft attributed a recent global outage affecting various digital infrastructures to a "CrowdStrike update," which disrupted multiple applications including OneDrive, OneNote, Outlook, PowerBI, Microsoft Teams, and others. Users experienced issues such as synchronization failures and access difficulties. The incident highlights vulnerabilities in supply chains that organizations rely on for managing sensitive data, which can be targeted by cyber threats. Data Loss Prevention (DLP) is a feature within Microsoft Purview designed to protect sensitive information from unauthorized disclosure. DLP policies can monitor user activity and take protective actions like alerting users about inappropriate sharing, blocking sharing attempts, or relocating data to secure locations. DLP can be applied across various platforms, including Office 365 applications and Windows endpoints. The DLP lifecycle includes planning and deployment phases, where organizations assess data to be monitored and ensure policies do not disrupt workflows. Monitoring and reporting tools provide insights into policy matches and incidents, helping organizations refine their DLP efforts. However, DLP has limitations, including false positives, user resistance, and challenges in detecting data leakages through new communication channels.

‘BrowserVenom’ Windows Malware Preys on Users Looking to Run DeepSeek AI

A new strain of Windows malware called "BrowserVenom" is exploiting interest in DeepSeek's AI models by targeting users through deceptive Google ads. These ads lead to a counterfeit website, "https[:]//deepseek-platform[.]com," where users are tricked into downloading a harmful file named “AILauncher1.21.exe.” This malware monitors and manipulates internet traffic, allowing attackers to intercept sensitive data. The operation is believed to involve Russian-speaking threat actors, and the malware has infected users in several countries, including Brazil, Cuba, Mexico, India, Nepal, South Africa, and Egypt. The fraudulent domain has been suspended, but the malware can evade many antivirus solutions. Users are advised to verify official domains when downloading software.

That ‘unsubscribe’ link is actually a hidden security risk

The "click to unsubscribe" button in emails may pose a security threat, as engaging with it can lead users to malicious websites. TK Keanini, CTO at DNSFilter, noted that about one in every 644 clicks on such links can direct users to phishing sites designed to steal sensitive information and introduce malware. Experts advise skepticism towards unsubscribe requests from untrusted senders and recommend using "list-unsubscribe headers" in email clients for safer management of subscriptions. Alternatives include using spam filters, blacklisting senders, and employing disposable email addresses for added protection. Additionally, having robust antivirus software is crucial for safeguarding against potential malware threats.

APT Hackers Exploited WebDAV 0-Day RCE Vulnerability in the Wild to Deploy Malware

A cyberattack campaign by the advanced persistent threat group Stealth Falcon targeted a prominent Turkish defense company using a zero-day vulnerability identified as CVE-2025-33053. This vulnerability allowed attackers to manipulate the working directory of legitimate Windows tools to execute malware from their WebDAV servers. The attack was initiated through a spear-phishing email containing a malicious .url file that directed the system to a legitimate Internet Explorer utility, which was then exploited to execute malicious files. The attackers employed process hollowing to bypass traditional defenses. Stealth Falcon, also known as FruityArmor, has been conducting cyber espionage since at least 2012, targeting government and defense sectors in Turkey, Qatar, Egypt, and Yemen. The attack involved a multi-stage infection chain leading to the deployment of "Horus Agent," a custom implant designed for advanced reconnaissance and equipped with anti-analysis techniques. Researchers identified additional custom tools used by Stealth Falcon, including a DC Credential Dumper and a custom keylogger. The group utilizes repurposed legitimate domains to blend their infrastructure with legitimate traffic, complicating detection efforts.

Cryptostealing Malware Found in Printer Software Highlights Growing Supply Chain Threat

A cybersecurity incident involving Procolored printers revealed vulnerabilities in everyday hardware, as users may have downloaded malware capable of stealing cryptocurrencies like Bitcoin. Tech content creator Cameron Coward reported an antivirus alert linked to Procolored printer software, prompting an investigation by G Data researchers who found malicious code in installation files on the manufacturer's website. The identified threats included a remote access tool (Win32.Backdoor.XRedRAT.A) and a cryptocurrency wallet stealer (MSIL.Trojan-Stealer.CoinStealer.H). Compromised files were last updated in October 2024 and distributed through official channels. The company initially denied the issue but later removed the downloads from their website in May 2025 and acknowledged the malware might have been introduced via USB transfers. An analysis of an attacker’s wallet showed a total of 9.3 BTC accumulated across 330 transactions before it was emptied. Cybersecurity experts recommend that users conduct antivirus scans and consider reformatting drives and reinstalling operating systems if infections are suspected.

These apps tricked Google to list them in the Play Store and you must delete them from your phone

The Google Play Store has been infiltrated by deceptive applications that are part of a phishing campaign, as revealed by an investigation by Cyble. These applications mimic legitimate digital wallets, including names like SushiSwap, PancakeSwap, Hyperliquid, and Raydium, and have utilized over 50 domains to evade detection. The primary threat involves the extraction of users' mnemonic phrases, which are critical for accessing cryptocurrency and tokens. Users are advised to uninstall nine specific apps identified by Cyble: Pancake Swap, Suite Wallet, Hyperliquid, Raydium, BullX Crypto, OpenOcean Exchange, Meteora Exchange, SushiSwap, and Harvest Finance Blog, to protect their digital assets. Although many of these malicious apps have been removed from the Play Store, the risk persists for those who still have them installed.
