NoVoice malware hit 2.3 million Android devices through apps Google never should have approved

McAfee researchers discovered a complex Android rootkit campaign, dubbed Operation NoVoice, that infiltrated 50 applications on Google Play, exploiting vulnerabilities in the kernel that had been patched but not uninstalled. The malware was resilient enough to survive factory resets and was concealed within seemingly benign apps, which collectively garnered 2.3 million downloads. The malicious payload was hidden in the com.facebook.utils package and used steganography to embed an encrypted payload within a PNG image. The malware conducted multiple checks to avoid detection and established contact with a command-and-control server, polling for exploit packages every 60 seconds. It utilized 22 distinct exploits, including vulnerabilities that had received patches between 2016 and 2021. The malware disabled SELinux enforcement and installed a persistent rootkit that could survive factory resets. Google confirmed the removal of the infected apps but noted that users who had already downloaded them remained at risk, especially if their devices were running unpatched Android versions. McAfee advised affected users to treat their devices as compromised and consider professional inspection or hardware-level storage wiping for remediation.

Another spyware maker caught distributing fake Android snooping apps

The Italian digital rights organization Osservatorio Nessuno has revealed a new malware called Morpheus, used by government agencies for surveillance. Morpheus is disguised as a phone updating application and can extract various data from targets' devices. The spyware is linked to IPS, an Italian firm specializing in lawful interception technologies, which claims to operate in over 20 countries. Morpheus is categorized as "low cost" due to its straightforward infection method, which involves tricking targets into installing the software. Authorities collaborated with the target's mobile service provider to obstruct data and send an SMS prompting the installation of the malware. Once installed, Morpheus exploits Android's accessibility features to access extensive information and masquerades as the WhatsApp application to solicit biometric data. The spyware's code contains Italian phrases and references to "Gomorra," indicating its connection to the Italian spyware industry. The attack is likely linked to political activism in Italy. IPS is among several Italian spyware manufacturers that have emerged following the decline of Hacking Team.

Blizzard forgot to turn off x-ray vision in World of Warcraft’s new prop hunt mode, so you can imagine how fair the matches are right now

Players in World of Warcraft's Decor Duels mode can disguise themselves as furniture, but the gameplay is hindered by the active "track humanoids" ability, which allows players to easily locate opponents. This ability can be used by hunters or activated by any player through a consumable item called Blackened Worg Steak. Additionally, some players have found ways to bypass arena barriers, reminiscent of exploits in Overwatch's prop hunt mode. Decor Duels is a new feature introduced in the latest patch, and players are concerned about fairness and balance in the game. The community is awaiting a patch to address these issues.

NGate Android malware uses HandyPay NFC app to steal card data

A new variant of the NGate malware targets Android users by disguising itself within a trojanized version of the HandyPay app, which is a legitimate mobile payment processing application. This malware, documented since mid-2024, siphons payment card information through the mobile device's near-field communication (NFC) chip and sends the stolen data directly to attackers, who create virtual cards for unauthorized purchases or cash withdrawals from NFC-enabled ATMs. The new variant has been injected with malicious code into the HandyPay app, which has been available on Google Play since 2021. The code includes emojis, indicating the possible use of a generative AI tool in its development. The shift from previous iterations, which used an open-source tool named NFCGate, to HandyPay is likely motivated by financial considerations and the need for evasion, as HandyPay is more affordable and requires fewer permissions. This NGate variant has been active since November 2025, primarily targeting Android devices in Brazil. It employs two main distribution methods: a counterfeit app named “Proteção Cartão” hosted on a fraudulent Google Play page and a fake lottery website that redirects users to WhatsApp to download the malicious APK. Upon installation, the app prompts users to set it as their default NFC payment application, requests their card PIN, and instructs them to tap their card on the phone for reading, transmitting all collected information to an attacker's email address. To protect against such threats, Android users are advised to avoid downloading APKs from outside Google Play, disable NFC when not in use, and use Play Protect to scan for threats.

New NGate Android malware variant uses NFC app to steal card data

A new variant of the NGate Android malware exploits a legitimate NFC payment app, HandyPay, to steal users' card information and PINs, enabling unauthorized contactless transactions. This malicious version of HandyPay, which has been available since 2021, was identified by ESET researchers and is distributed through a fraudulent lottery website and a fake Google Play page. The malware captures sensitive information by prompting users to enter their payment card PIN and tap their card against the device, sending the data to an attacker-controlled phone and exfiltrating the PIN to a command-and-control server. The campaign employs social engineering tactics and requires minimal permissions, relying on users to enable app installations from unknown sources. The attackers use a centralized infrastructure for malware distribution and PIN collection, with evidence of compromised devices in Brazil. The shift to modifying a legitimate application is motivated by financial incentives, as it offers similar functionality at a lower cost compared to underground tools. Users are advised to avoid installing apps from unofficial sources and to ensure the legitimacy of applications before entering sensitive information.

RedSun: Windows 0day when Defender becomes the attacker

A vulnerability has been discovered in Windows Defender that allows standard users to exploit a logic error in the file remediation process, enabling code execution with elevated privileges without administrative access. This flaw, identified by security researcher Chaotic Eclipse, occurs because Windows Defender does not verify if the restoration location of flagged files has been altered through a junction point. The exploit, named RedSun, takes advantage of a missing validation in the MpSvc.dll file, allowing attackers to redirect file restoration to the C:WindowsSystem32 directory. RedSun operates by chaining together four legitimate Windows features: Opportunistic Locks (OPLOCKs), Cloud Files API, Volume Shadow Copy Service (VSS), and Junction Points. The execution of the exploit involves monitoring shadow copies, triggering Defender's detection, synchronizing OPLOCKs, and ultimately writing malicious binaries to the System32 directory. The root cause is the lack of reparse point validation in the restoration process, and currently, no patch or CVE has been assigned for this vulnerability. It affects Windows 10, Windows 11, and Windows Server 2019 and later, and organizations are advised to implement behavioral detection strategies until a fix is available.
