I4C warns against malicious Android apps from social media ads

The Indian Cyber Crime Coordination Centre (I4C) has issued an advisory about malicious Android applications disguised as adult-content apps, which are promoted through social media and distributed outside official app stores. The National Cybercrime Threat Analytics Unit (NCTAU) warned that these apps can compromise mobile device security by requesting sensitive permissions and may install additional software without user consent, leading to unauthorized financial transactions. Users are advised to download apps only from trusted sources like the Google Play Store, avoid installing APK files from unverified sources, and refrain from granting accessibility permissions to untrusted applications. Recommendations include regularly reviewing installed apps, keeping Google Play Protect enabled, and monitoring bank accounts for unauthorized activities. Victims of cyber fraud are encouraged to report incidents via the national cybercrime helpline or the government’s reporting portal.

Prolific Microsoft 0-day hunter drops CrowdStrike Falcon exploit PoC

Nightmare Eclipse, a security researcher known for identifying vulnerabilities in Microsoft products, has shifted focus to other vendors, revealing a zero-day vulnerability called FalconFlank that targets CrowdStrike’s Falcon endpoint security platform. FalconFlank is a privilege escalation vulnerability that exploits the Microsoft Office malicious macros remediation feature within CrowdStrike Falcon. CrowdStrike is investigating the claims and advises customers to disable the Microsoft Office File Suspicious Macro Removal Windows policy setting while assuring them of continued protection through Cloud Anti-malware settings. The exploit works on fully updated Windows 11 25H2 and Windows Server 2025 systems running CrowdStrike Falcon with Optimal Protection enabled. Nightmare Eclipse has also discovered other vulnerabilities, including HardBreacher affecting Kaspersky’s endpoint antivirus and PrettyPrague in Gen Digital’s Avast antivirus, which allows attackers to dump the SAM database. Gen Digital is developing a patch for the Avast vulnerability, while Kaspersky has not commented. Additionally, Nightmare disclosed a memory corruption zero-day vulnerability in Nvidia, named GreenSection, which causes system crashes.

Fake porn apps that can hijack your Android phone

The National Cybercrime Threat Analytics Unit (NCTAU) has reported a rise in financial fraud linked to deceptive Android applications that pose as pornography apps. These apps are advertised on social media platforms like Facebook and Instagram under names such as ‘Night Play’, ‘Reloop’, ‘Kyss’, ‘Vimo’, ‘Rivo’, ‘Nexo’, and ‘Vixa’. Users who click on these ads are redirected to websites promising adult content, where they are encouraged to download APK files. Once installed, these apps often request sensitive permissions, particularly Accessibility access, which can allow malware to take control of the device and facilitate financial fraud. Some malicious apps may also install a VPN, rerouting internet traffic through servers controlled by attackers and exposing sensitive data. The malware is primarily promoted through ads linked to pornographic content, redirecting users to phishing websites that prompt APK downloads from non-Google Play sources, often using the “.live” domain extension. After installation, the initial app may download a second malicious package disguised as an update, exploiting the permissions granted to the original app.

Fake Software Installers Disable Windows Update and Weaken Microsoft Defender

An active malware campaign is using counterfeit software-download websites to distribute malicious installers, primarily targeting users seeking popular software. This campaign has significantly affected China-based operations of multinational corporations and Chinese-speaking users. The malware, once executed, can establish persistence, undermine security measures, and communicate with attacker-controlled infrastructure. Victims span various sectors, including healthcare, manufacturing, gaming, technology, logistics, government, and education. Microsoft associates this campaign with a Chinese threat cluster called Silver Fox, known for using spoofed vendor download pages to spread Gh0st RAT and ValleyRAT. The malicious websites are hosted on .com.cn and .hl.cn domains, featuring Chinese-language content. The downloaded files are dynamically generated, and upon execution, they deploy a wrapper installer that initiates the malware payload. The malware achieves persistence through scheduled tasks and interferes with Windows Update services. The campaign establishes command-and-control communication over non-standard ports, with two identified domains linked to the activity. Microsoft Defender has detected the threat and initiated containment procedures. Kaspersky reported a related malicious installer exploiting a legitimate adware application to execute a backdoor, which captures keystrokes and clipboard contents. ValleyRAT, a sophisticated implant, can collect system information, reboot the computer, capture screenshots, and transmit logs. The attackers are motivated by cyber espionage and financial gain, targeting organizations globally. A subgroup within GoldenEyeDog, known as CuboidalCanine, has also been linked to the use of ValleyRAT, particularly in the gambling industry. In June 2026, Chinese authorities addressed cybercrime cases involving a new variant of the Silver Fox trojan.
