Iran has introduced its second domestically developed antivirus software, Ayyza, which utilizes artificial intelligence and machine learning to detect known and unknown cyber threats. The antivirus is designed to protect against malware, viruses, Trojans, ransomware, and advanced persistent threats (APTs). Ayyza's detection engine is developed in-house and operates at the Windows kernel level to enhance detection accuracy and speed while minimizing hardware resource consumption. It can receive updates offline or via Iran’s National Information Network. Ayyza's machine-learning capabilities allow it to identify emerging threats, including previously unknown malware and zero-day vulnerabilities. The company has also created complementary security tools, such as privileged access management (PAM) systems and data leakage prevention tools, to enhance overall cybersecurity. The company's products are currently used in various Iranian infrastructures, including banking, financial, and governmental systems.

Android Auto was designed for simplicity, but users want more functionality like streaming YouTube or screen mirroring. Sideloading allows users to install unapproved apps, unlocking additional features, though it poses risks to security, reliability, and safety. To sideload apps, users must enable Developer Mode on their phone and Android Auto, then install the Android Auto Apps Downloader (AAAD) and explore open-source apps like CarStream and AAMirror. Risks of sideloading include safety concerns with video streaming while driving and increased exposure to malware, as sideloaded apps bypass Google’s security checks. Google plans to introduce new verification requirements for developers starting in late 2026 to mitigate these risks. Most drivers find the standard Android Auto experience sufficient, and sideloading should be approached cautiously.

The cyber threat group Silver Fox is distributing the ValleyRAT backdoor disguised as a legitimate signed Chinese adware application, specifically bundled with the QN Wallpaper tool. This malware allows attackers to gain comprehensive control over infected machines, enabling them to collect sensitive information, capture screenshots, and deploy additional malicious modules. The attack utilizes DLL sideloading, where a modified version of QN Wallpaper loads a malicious DLL from the same directory, circumventing signature-based security measures. The installer disables Windows Defender, adds itself to autorun entries, and uses the "runas" command to elevate privileges if the user lacks administrator rights. ValleyRAT also marks its process as critical, potentially causing a blue screen of death if terminated. Kaspersky has identified Silver Fox as the likely perpetrator of this campaign, known for similar techniques.

Solipsism Browser is a third-party, open-source browser based on Chromium, launched just over three months ago. It features a unique side-rail design for navigation buttons, allowing for ergonomic one-handed use, especially on larger devices. Users can customize the homepage with HTML and CSS, and it includes a built-in ad blocker powered by uBlock Origin and a malware scanner. However, it lacks extension support, which is a strength of Firefox, and the address bar's placement at the top can hinder one-handed usability. Solipsism is not available on the Google Play Store and requires updates through platforms like F-Droid or Obtanium. The developer plans to create a future version based on the Servo engine.

NordVPN's next-generation antivirus achieved a 94% phishing detection rate in an anti-phishing test by AV-Comparatives, ranking third among nine products, behind Avast One Free Antivirus and Norton Antivirus Plus, both at 96%. The evaluation tested 250 live phishing URLs and recorded zero false positives for NordVPN, unlike competitors such as Malwarebytes Premium and Webroot SecureAnywhere. The two-percentage-point difference between NordVPN and the leaders corresponds to five URLs. Other products like Dr. Web Security Space and K7 Total Security had lower detection rates of 57% and 70%, respectively. Previously, NordVPN's Threat Protection Pro had an 83.42% detection rate across 3,209 links, outperforming IPVanish. In June 2024, NordVPN became the first VPN provider to earn AV-Comparatives' anti-phishing protection badge, requiring a minimum detection rate of 85% with zero false alarms. The antivirus feature is available on Plus plans and higher, previously known as Threat Protection Pro, and is included in Plus, Complete, and Prime tiers.

Microsoft has identified a new malware campaign called TerminalFix that uses fake CAPTCHA prompts to trick Windows users into executing malicious commands. This campaign is a variation of ClickFix attacks and employs deceptive pages that impersonate reputable services like Cloudflare. Instead of traditional CAPTCHA challenges, users are instructed to open PowerShell or Command Prompt and paste in commands, allowing attackers to execute complex scripts more easily. TerminalFix initiates a multi-stage intrusion, granting attackers persistent proxy access to the infected machine, which can lead to further exploitation of the company's network. The campaign relies on social engineering tactics, requiring user compliance with counterfeit verification instructions. Microsoft has released mitigation guidance, recommending restrictions on PowerShell access, monitoring for DLL sideloading, blocking outdated Flash plugins, and enabling cloud-delivered protection in Microsoft Defender Antivirus. The campaign poses significant risks to enterprise networks, but individual users should also be cautious about executing commands requested by websites.

Norton and Bitdefender both have a malware detection rate of 99.8%. Norton excels in phishing protection, blocking 95% of phishing attempts compared to Bitdefender's 89%. In terms of system impact, Bitdefender uses 11% CPU and 183 MB RAM during scans, while Norton uses 23% CPU and 384 MB RAM. Norton offers features such as cloud backup, parental controls, and unlimited VPN, whereas Bitdefender lacks cloud backup and has a limited VPN. Pricing for both is competitive, but Bitdefender generally has cheaper renewal costs. Norton provides faster customer support response times. In a comparison of nine categories, Norton won five and Bitdefender won three. For users needing backup and parental controls, Norton is preferred; for those with older laptops, Bitdefender is recommended.
