Centre cracks down on Android scam; blocks fraud app, Telegram channels, warns users

The Indian government has taken action against the Wingo app, a cyber fraud network that sent fraudulent SMS messages from users' devices without consent. The app's digital infrastructure has been blocked, and four associated Telegram channels with 153,000 users have been shut down. Over 53 related videos have been removed from YouTube. The Wingo app lured users with promises of quick financial gains, encouraging them to deposit funds for minor tasks or investments, but then either shut down or blocked accounts after receiving money. Payments were made through UPI or personal wallets, complicating traceability. Users were asked for access to personal data and provided with fake customer care numbers. Android users are advised to avoid apps promising guaranteed profits, verify app legitimacy, and refrain from granting unnecessary permissions. The government recommends uninstalling suspicious apps and reporting them, as well as contacting the cybercrime helpline at 1930 for assistance.

Hack alert as Android users warned to uninstall these risky apps

HUMAN's Satori Threat Intelligence and Research Team has identified and dismantled an ad fraud scheme called SlopAds, linked to 224 applications that have over 38 million downloads from Google Play across 228 countries. The perpetrators used techniques like steganography to embed fraudulent payloads in apps, creating hidden WebViews that redirected users to cashout sites for generating illegitimate ad impressions and clicks. Google has removed all identified malicious applications and will notify affected users to uninstall them. Users are encouraged to enable Google's Play Protect feature to prevent future threats. Ad fraud poses risks to advertisers and developers by tricking ad networks into accepting fraudulent ads. Invalid traffic can arise from developers using prohibited ad practices, undermining trust in the mobile advertising ecosystem. Users are advised to uninstall flagged applications to protect their devices.

Beware of this Android antivirus. It actually steals data, records audio, and tracks you

LunaSpy is a deceptive antivirus application that spreads primarily through Telegram and is not available on the official Google Play Store. It masquerades as a legitimate antivirus program, claiming to protect online banking activities. Upon installation, it conducts a superficial scan and displays false warnings to instill fear, prompting users to grant extensive permissions. Once installed, it can invade personal data, access banking information, record audio and video, steal passwords, read SMS messages, track locations, and has been found to include a command for photo theft. Users are advised to avoid downloading LunaSpy and to exercise caution with applications from social networks or unofficial sources, relying instead on verified antivirus solutions from official app stores.

Hackers can bypass Microsoft Defender to install ransomware on PCs

A significant vulnerability in Microsoft Defender has been identified, allowing hackers to bypass the software and deploy Akira ransomware. This vulnerability exploits the legitimate driver rwdrv.sys, associated with the Intel CPU tuning tool ThrottleStop, granting cybercriminals kernel-level access to a target PC. Once access is obtained, hackers can introduce the driver hlpdrv.sys to manipulate the Windows Registry, disabling Microsoft Defender's protective measures. GuidePoint Security has noted that this method has been increasingly used in Akira ransomware attacks since July of this year. Users are advised to use reputable antivirus software and keep it updated to protect against such threats.

How Can An Image Become A Weapon? Unpacking the RoKRAT Threat To Windows Users

Cybercriminals are using a sophisticated attack method involving a remote access trojan called RoKRAT, which is embedded within standard JPEG image files. This technique, a variant of steganography, allows the malware to evade detection by conventional security systems. The attack is linked to an advanced persistent threat group known as APT37. The process involves embedding a malicious module within a JPEG file, which, when opened, triggers the malware to inject its code into the MS Paint application. Researchers found that the RoKRAT module is often concealed in images downloaded from cloud storage services, complicating detection efforts. Authorities are warning users to exercise caution with files from unverified sources and to keep their security systems updated.

This Stealthy Malware Takes Control of Your Computer to Steal Your Data

Skitnet is a new malware that targets personal data by stealthily infiltrating computer systems. It is used by hackers to steal sensitive information through advanced methods, including the insertion of invisible malicious code in emails and the creation of fraudulent websites. Cybersecurity experts from PRODAFT have revealed that Skitnet is often employed by ransomware groups and can remotely control infected computers using services like AnyDesk. The malware operates discreetly, monitoring user actions without detection for extended periods, making it difficult for victims to realize they are infected until after data theft occurs. To protect against such threats, security specialists recommend identifying suspicious emails, using reliable antivirus software, and enhancing account security with two-step verification and strong passwords.

These dangerous Android apps are installed 2.5 million times each month

Kaleidoscope is an ad-fraud attack targeting Android users by exploiting legitimate applications on the Google Play Store and offering malicious duplicates through third-party app stores. Approximately 2.5 million devices are affected monthly, with 20% of incidents occurring in India, and other impacted regions include Indonesia, the Philippines, and Brazil. Users unknowingly download legitimate-looking apps while malicious versions circulate elsewhere, leading to intrusive advertisements that disrupt user experience and generate revenue for cybercriminals. Google has removed flagged titles from the Play Store and is enhancing protections, but ad resellers often fail to properly vet their inventory. The adware causes device overheating, rapid battery drain, and sluggish performance, highlighting the need for user vigilance.

Akira Ransomware Targets Windows Servers via RDP and Evades EDR with Webcam Trick

The Akira ransomware group has demonstrated its ability to bypass Endpoint Detection and Response (EDR) tools by exploiting an unsecured webcam. In 2024, Akira was responsible for 15% of ransomware incidents addressed by the S-RM team. The group typically gains access through remote access solutions and uses tools like AnyDesk.exe. In a recent attempt to deploy ransomware on a Windows server, their initial effort was thwarted by EDR detection. Subsequently, they conducted an internal network scan and targeted a vulnerable webcam, which lacked EDR protection. By compromising the webcam, Akira deployed Linux-based ransomware to encrypt files across the victim’s network. This incident highlights the need for organizations to patch and manage IoT devices, audit networks for vulnerabilities, implement network segmentation, and monitor IoT traffic for anomalies.
