What a smart firewall does and why it matters on home Wi-Fi

Home Wi-Fi connects various devices and presents security risks, making firewalls important for network protection. A router firewall is built into the home router and protects all connected devices, while a software firewall operates on individual devices for additional security. Inbound traffic is data coming to a device, while outbound traffic is data leaving it; firewalls analyze this traffic to manage connections. Network security is critical as sensitive information is often accessed on devices used for leisure, and remote work increases data overlap. Firewalls can control network connections and filter unwanted traffic but cannot replace weak passwords or antivirus protection. To enhance home network security, users should secure router settings, keep routers updated, strengthen Wi-Fi access, check connected devices, and replace outdated routers. A comprehensive security strategy includes keeping software updated, using multifactor authentication, being cautious with links, and strengthening firewalls with antivirus protection. Protecting valuable data is essential, and understanding ransomware risks is crucial. The 3-2-1 backup strategy involves maintaining three copies of data on two different storage types, with one copy offsite. Regularly testing backups and knowing how to respond to ransomware incidents are also important.

TerminalFix Attacks Use Fake CAPTCHAs To Secretly Hack Windows PCs

Microsoft Threat Intelligence has identified a new variant of the ClickFix malware campaign called "TerminalFix." This variant uses deceptive CAPTCHAs that mimic trusted services like Cloudflare and directs users to PowerShell or a command prompt, allowing for the execution of complex scripts. TerminalFix aims to orchestrate a multi-stage attack that provides attackers with persistent, network-level proxy access through the compromised host, potentially leading to significant data theft and malware propagation within unsecured enterprise networks. Recommendations for defense against TerminalFix include restricting access to PowerShell and Windows Run dialogs, monitoring for DLL sideloading indicators, blocking Flash plugins, and enabling cloud-delivered protection in Microsoft Defender Antivirus. The attacks primarily target enterprise environments rather than individual consumers.

Microsoft explains that it’s fixing a bug in Windows 11’s antivirus that’s happening ‘intermittently’ and is likely to fool people into thinking that Defender is broken

Windows 11's antivirus, Microsoft Defender, is experiencing issues following recent updates, erroneously notifying users that it is turned off despite functioning normally. This glitch has led to persistent alerts prompting users to reactivate the antivirus, causing confusion and frustration. Microsoft has acknowledged the issue on its health dashboard, stating that notifications may appear claiming Microsoft Defender is disabled, even though it is active. This problem has been reported for over a week and may date back to early August, with users advised to check the operational status of their antivirus through Windows Security.

How to make sure your Android phone is secure

Android devices have various features to enhance security and privacy. A 2025 Pew Research Center study found that nearly 75% of Americans have faced online scams, which have become more sophisticated, including vishing scams using AI-generated deepfakes. Android offers tools to mitigate these risks, such as AI-driven scam detection and theft protection. To safeguard devices, users should keep their software updated by checking Settings > About Phone for the current version and navigating to Settings > System > Software Updates for updates. App updates can be managed through the Google Play Store under Settings > Network preferences > Auto-update apps. Securing Google accounts with two-factor authentication is recommended, which can be set up via the Google Account management page. Automatic backups can be enabled in Settings > Google > Backup. The Find Hub app helps track lost devices and can be configured in Settings > Location and Settings > Security. Android includes scam detection tools that alert users to potential scams in calls and texts, which can be activated in the Phone app settings. Privacy settings can be managed by adjusting app permissions in Settings > Apps and using the Permission manager in Security & Privacy. Users can opt out of data sharing with advertisers by navigating to Settings > Google > Ads. Google Play Protect scans for harmful apps and should remain enabled for safety. Theft protection features, such as Theft Detection Lock and Remote Lock, can be activated in Settings > Google > Personal & device safety.

Fake Microsoft Security Scan Tells You to Remove Antivirus—Then Scammers Ask for Remote Access

A new web-based scam is using counterfeit Microsoft-branded security scans to deceive users into uninstalling their antivirus software. The scam websites conduct fake inspections, reporting false security failures and claiming third-party antivirus products are unsupported by Windows. They gather browser information to create customized-looking scan reports and aim to mislead victims into a fraudulent refund process. Investigators have identified 11 related scam sites under the name SysScan, which present themselves as legitimate Microsoft security checks. The scam does not involve file downloads but relies on convincing websites, fabricated security scores, and personal information forms. The scan results are hard-coded, and the security score is limited to a range between 13 and 30 out of 100. The scams instruct users to uninstall antivirus software, which is misleading since Windows does not cease support for third-party antivirus solutions. The scam sites request extensive personal information, including names, addresses, phone numbers, and banking details, and redirect victims to a page claiming a refund manager will call shortly. This process allows scammers to gain remote access to victims' computers. Indicators of compromise include specific IP addresses and domains associated with the scam.

Fake Chrome update scam could infect your computer

A fake Chrome update scam has emerged, linked to a Chrome extension called Enable Right Click & Copy - Smart Unlock + OCR, which was initially legitimate but later compromised. The extension had around 70,000 users before being removed from the Chrome Web Store on August 14 due to its malicious nature. Users may encounter deceptive warnings while browsing benign sites, urging them to download files instead of using Chrome's built-in update mechanism. Google advises against engaging with suspicious pop-ups requesting software installations. The scam highlights that trusted extensions can become threats without warning, and users should regularly review their installed extensions and check for updates directly within Chrome. Similar fake update alerts have also been reported in other Chromium-based browsers. Users are encouraged to adopt safety measures, such as using strong antivirus software, reviewing browser extensions, and being cautious with downloaded files. If a suspicious file has been executed, users should treat their computer as potentially compromised and take appropriate security actions.

This feature keeps distracting spam calls away while using Android Auto

Google's Call Screen feature allows users to manage unknown calls by delegating the initial interaction to Call Assist, which identifies the caller and provides context. This feature is now integrated with Android Auto, although the screening process itself remains a function of the phone. Call Screen operates in two modes: manual, where users can choose to screen calls, and automatic, which silently screens certain unknown calls and hangs up on spam. Call Screen works directly on the device without needing Wi-Fi or mobile data, and call audio and transcripts are not stored in the user's Google Account. To set up Call Screen, users must do so through the Phone by Google app. Compatibility with Android Auto and Call Screen varies by phone model and geographical location, with automatic screening primarily available on Pixel phones in the U.S. Manual screening is accessible in several countries, and some selected Android devices may also support it. Not all call screening features are the same across different brands, and practical limitations exist for automatic Call Screen, such as functionality issues when connected via Bluetooth or while roaming.
