Microsoft 365 Android Apps Let Any App Steal Account Tokens via Leftover Debug Flag

A vulnerability in several Microsoft 365 Android applications, identified as FlagLeft, was caused by a development flag left enabled in production builds, which disabled checks meant to restrict account-token sharing to trusted applications. This flaw affected applications such as Word, PowerPoint, Excel, Microsoft 365 Copilot, Microsoft Loop, and OneNote, allowing unauthorized apps to request and obtain user tokens without permission. Microsoft Teams was unaffected. The vulnerability was demonstrated by Enclave, allowing access to user emails through an unverified app. On May 12, Microsoft issued four CVEs for the affected applications, categorized under improper access control. The patched version of Word for Android is 16.0.19822.20190, and users are advised to update their applications. The patch does not invalidate already compromised tokens, so users should revoke these tokens and sign in again.

Fake ‘Cockroach Janta Party’ Android app flagged as critical malware threat, report warns

A cybersecurity report released on May 22, 2026, identifies a counterfeit Android application posing as the official app of the Cockroach Janta Party as a significant malware threat. The malicious app, known as Cockroach.Janta.Party, functions as a Remote Access Trojan (RAT) and can infiltrate Android devices, steal sensitive information, intercept communications, and control infected smartphones. The genuine Cockroach Janta Party has no affiliation with this app and is a victim of brand impersonation. The app is distributed through WhatsApp, Telegram, and misleading websites, particularly a rogue domain, cockroachjantaparty[.]org. It targets Android devices running versions 8.0 to 14 and requests elevated permissions, including access to camera, SMS, call logs, and contacts, while misusing the Android Accessibility Service to read on-screen content and grant itself additional permissions. The app contains multiple malicious modules for data exfiltration and uses a Command and Control infrastructure based on the Telegram Bot API. Users are advised to uninstall the app, disable Accessibility permissions, reset banking credentials, enable two-factor authentication, and conduct a full mobile security scan. The legitimate Cockroach Janta Party is encouraged to issue a formal clarification regarding the impersonation.

Android 16 Bug Allows Apps to Ignore VPNs and Leak IP Addresses

Android 16 may have a vulnerability that allows applications to bypass VPN protections, potentially exposing users' IP addresses. A security engineer reported this issue through Google’s Vulnerability Reward Program, but Google's security team deemed it "infeasible" to address. The vulnerability lies within the ConnectivityManager system service, which circumvents the VPN tunnel, leading to unencrypted traffic and exposure of sensitive information. This issue persists even with "Always-on VPN" or "Block connections without VPN" features enabled. Although there is no confirmed exploitation of this vulnerability, it poses ongoing risks for users. GrapheneOS has patched the issue, indicating a fix is possible. A debug command has been identified as a temporary workaround for affected users, but it requires caution and understanding of USB debugging mode.

10,000 Users Exposed As Fake Document Reader App Delivers Anatsa Banking Trojan

Security researchers from ThreatLabz discovered a malicious document reader app on the Google Play Store that delivered the Anatsa Android banking trojan. The app, which had over 10,000 downloads before its removal, disguised itself as a legitimate file management tool using the package name com.groundstation.informationcontrol.filestationbrowsefilesreaddocs. It employed a "dropper" technique to hide its malicious code, connecting to an external server to retrieve the malware payload after installation. Anatsa is designed to steal financial information by overlaying a fake login screen over legitimate banking apps, capturing user credentials and enabling unauthorized transactions. Users are advised to delete the app and monitor their financial accounts. Technical indicators for identifying infections include the Anatsa Installer SHA256 (5c9b09819b196970a867b1d459f9053da38a6a2721f21264324e0a8ffef01e20), Payload URL (http://23.251.108[.]10:8080/privacy.txt), Payload SHA256 Hash (88fd72ac0cdab37c74ce14901c5daf214bd54f64e0e68093526a0076df4e042f), and Command and Control servers (http://172.86.91[.]94/api/ and http://193.24.123[.]18:85/api/).

Research company claims spyware posing as Israel’s Red Alert Android app targeting users

Acronis Threat Research Unit (TRU) has uncovered a cyber espionage campaign targeting Israeli civilians through a fake version of the Red Alert app. The attack begins with a deceptive text message claiming to be from Israel's Home Front Command, urging users to download an updated app due to a malfunction. The fraudulent app closely resembles the legitimate Red Alert app but contains malware that collects sensitive personal information, including messages, contacts, location data, and device account details. This data is stored locally and then transmitted to a remote server controlled by the attackers. The hackers use certificate spoofing and other techniques to bypass Android's security measures, making the malicious app appear legitimate. Cybersecurity experts recommend that Israeli users take precautions to protect their personal information.

How to Run an iPhone Malware Scan: Find and Remove Viruses

iPhones do not support traditional antivirus applications due to iOS's app sandboxing feature, which limits apps' access to system-level data. Users can identify potential malware by monitoring for unusual behaviors, such as overheating, fast battery drain, unexpected data usage spikes, unwanted Safari pop-ups, unfamiliar apps, repeated login prompts, and strange messages sent from their accounts. To investigate for malware, users should check device performance, review storage and data usage, monitor battery usage, and look for jailbreak indicators. If malware is suspected, users can take steps such as updating iOS and apps, restarting the device, deleting suspicious apps, clearing Safari data, removing unknown profiles, resetting network settings, restoring from a clean backup, or performing a factory reset as a last resort. iOS includes built-in protections against malware, such as App Store reviews, sandboxing, code signing, and regular security updates. However, iPhones are not completely immune to threats, and jailbreaking increases vulnerability. To protect against malware, users should keep iOS and apps updated, use strong passcodes, avoid jailbreaking, be cautious with links and attachments, use secure browsers, and consider using a VPN on public Wi-Fi. CyberGhost VPN can provide additional security on unsecured networks by encrypting internet traffic. While iPhones do not have built-in malware scanners, they incorporate various protections to prevent malware from reaching the device. Signs of potential malware include overheating, rapid battery drain, unexpected data usage spikes, and unusual app behavior. Malicious apps can occasionally bypass App Store scrutiny, and users should take immediate action if they suspect an infection. Generally, iPhones are considered more secure than Android devices due to stricter app controls.
