Fake Microsoft Edge, Kaspersky and Razer Installers Used to Compromise Windows Systems

An ongoing malware campaign is targeting Windows devices through counterfeit download pages for well-known software brands like Microsoft Edge, Kaspersky, and Razer. The campaign affects various sectors, including healthcare, manufacturing, gaming, technology, logistics, government, and education. It utilizes high-fidelity fraudulent websites that closely mimic legitimate vendors, with observed lure domains such as app-microsoft-edge[.]com[.]cn and kaspersky-lab[.]hl[.]cn. Attackers employ evasion tactics like server-side payload regeneration and create multiple copies of the same archive in quick succession. Victims are lured into downloading ZIP files that contain a bundled wrapper installer, which activates a stage-one executable in randomized directories. The malware often masquerades as legitimate software, with some payloads impersonating known applications. Persistence is achieved through scheduled tasks with unusual names, and the malware employs various evasion techniques, including deleting shadow copies and altering file permissions. Microsoft Defender has identified activity across multiple stages of the attack, including delivery, execution, and command-and-control communications. To mitigate risks, organizations are advised to block downloads from unofficial sources, enforce Tamper Protection, and implement Attack Surface Reduction rules. Indicators of compromise (IOCs) include specific lure domains and URLs associated with the campaign.

MHA issues advisory on malicious Android apps used to steal money, take control of phones

Cybercriminals are increasingly using malicious Android applications disguised as pornography apps to take control of users' devices and conduct unauthorized financial transactions. The Indian Cyber Crime Coordination Centre (I4C) has issued a warning about this trend. These apps are often promoted on social media and require users to download APK files from outside the Google Play Store. The National Cybercrime Threat Analytics Unit (NCTAU) has reported a rise in financial fraud linked to these applications, which include names like “Night Play,” “Reloop,” and “Kyss.” Once installed, these apps request sensitive permissions, such as Accessibility access, allowing malware to read screen information, click buttons, enter OTPs or PINs, confirm transactions, and initiate fund transfers, leading to unauthorized access to bank accounts. Additionally, the malware may install secondary applications or a VPN to reroute internet traffic through attacker-controlled servers, exposing sensitive data. These apps may also prevent uninstallation through standard device settings. The NCTAU advises users to only install apps from trusted sources, avoid unknown APK files, refrain from granting Accessibility permissions to unfamiliar apps, regularly review installed applications, and keep their devices updated. Users should monitor bank accounts for suspicious activity and, if compromised, restart in Safe Mode to uninstall malicious apps. If removal is difficult, backing up data and performing a factory reset is recommended. Citizens are encouraged to report fraudulent applications or cybercrime incidents through the national cybercrime helpline 1930 or the government’s reporting portal.

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.

Fake Porn Apps Target Android Users Via Ads On Facebook, Instagram: How To Stay Safe

Cybercriminals are targeting Android users with deceptive advertisements for malicious applications disguised as pornographic content on platforms like Facebook and Instagram. The National Cybercrime Threat Analytics Unit (NCTAU) has reported that these ads lead users to phishing traps or malware downloads that can compromise banking credentials. Malicious applications linked to this threat include “Night Play,” “Reloop,” “Kyss,” “Vimo,” “Rivo,” “Nexo,” and “Vixa.” The scam involves promoting these apps through enticing ads, redirecting users to websites offering pornographic content, and prompting them to download APK files directly from these sites, often using “.live” domains. The initial app may request users to download a second package disguised as an update, which can exploit permissions granted to the first app. This malware can gain extensive control over the device, potentially installing a VPN that routes internet traffic through attackers' servers. To protect against this threat, users should download apps only from trusted sources, avoid installing APK files from ads or suspicious links, refrain from granting Accessibility access to unknown apps, regularly review installed apps, keep Google Play Protect enabled, and monitor bank accounts for unusual activity. If a suspicious app cannot be uninstalled, users can try Safe Mode, remove special permissions, or perform a factory reset as a last resort.

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.

ValleyRAT Backdoor Hides in Signed Adware That Users Add to Antivirus Exclusions

Silver Fox is linked to the distribution of a backdoor malware called ValleyRAT, disguised as the legitimate QN Wallpaper adware application. Once installed, ValleyRAT provides complete control over the compromised machine. The malware uses DLL sideloading to operate under the guise of a legitimate process, bypassing security measures. It disables Windows Defender and adds itself to autorun entries, and can mark its process as critical, causing system crashes if terminated. Kaspersky has identified specific indicators of compromise (IoCs) including hashes, command-and-control servers, and associated domains. In 2026, Kaspersky recorded over 100,000 detections of ValleyRAT affecting more than 1,500 unique users, mainly in China and India.
