Renting Android Malware With 2FA Interception, AV Bypass is Getting Cheaper Now

The cybercriminal landscape is experiencing a transformation with the emergence of malware-as-a-service (MaaS) platforms targeting Android devices, allowing individuals with minimal technical skills to deploy advanced mobile threats through accessible subscription-based malware kits. Notable platforms include PhantomOS, priced at 9 monthly, offering features like remote application installation and two-factor authentication bypass, and Nebula, starting at 0 monthly, which provides automated data extraction of SMS, call logs, and GPS data. Both platforms utilize Telegram for command and control, enabling easy management of infected devices. These MaaS platforms employ advanced evasion techniques, utilizing fully undetectable malware that can bypass major security measures, ensuring persistence and compatibility with various Android versions, including the latest Android 15. This shift signifies a move toward industrialized cybercrime, where specialized providers handle technical complexities, allowing criminals to focus on targeting victims.

Threat Actors Combine Android Malware With Click Fraud Apps to Steal Login Credentials

A new wave of malicious Android Package Kit (APK) files is combining click-fraud advertising and credential theft, primarily affecting regions like Southeast Asia, Latin America, and parts of Europe. These APKs disguise themselves as casual games or clones of legitimate apps, enticing users to sideload them and bypass Google Play’s security measures. Once installed, they request excessive permissions and operate in the foreground to inflate ad impressions while capturing user credentials through convincing login forms. The malware uses a modular configuration system and communicates with an encrypted command-and-control backend. The installation process often begins with social media messages or QR codes leading to spoofed landing pages. The app can embed secondary payloads without invalidating its original signature and minimizes detection by sandboxes. By the time users notice unusual activity, the malware has already exfiltrated ad revenue and credentials.

How Often Should You Update Your Antivirus Software?

Antivirus software protects devices from various digital threats, including viruses, Trojans, ransomware, and spyware. According to the 2025 Antivirus Statistics and Consumer Report, 75% of users believe their antivirus software effectively safeguards their devices. The effectiveness of antivirus software depends on the last update, as neglecting updates leaves devices vulnerable to emerging threats. Frequent updates are necessary because hackers continuously develop new malware. Failing to update antivirus software increases the risk of hacking and can degrade device performance. It is recommended to check for updates daily, perform manual checks weekly, and expect major updates every 3 to 6 months. Free antivirus software may offer limited protection and fewer updates, requiring users to be proactive in checking for updates.

Jack Dorsey evokes Bitcoin ethos with new decentralised messaging app Bitchat

Jack Dorsey introduced a test version of a decentralized messaging application called Bitchat, designed for private conversations through end-to-end encryption. The app enables ephemeral, encrypted communication without relying on internet infrastructure, making it resilient to network outages and censorship. Bitchat operates using Bluetooth to facilitate communication within a range of approximately 300 meters and does not require users to provide phone numbers or email addresses. Instead, users create their own handles for identification. The app automatically detects nearby users, allowing them to connect through chatrooms. Bitchat is intended for use in scenarios lacking internet access, such as concerts, airplanes, or during disaster response efforts.

В Греции администратора торрент-трекера приговорили к пяти годам тюрьмы

The Piraeus Court of Appeals has upheld a five-year prison sentence for a 59-year-old Greek man who operated the torrent tracker P2PLanet from 2011 to 2014, along with a €10,000 fine. The platform had over 44,000 users and 14,000 torrent files available before it ceased operations in 2014 after a cyberattack and the administrator's arrest. The Greek cybercrime unit raided the suspect's residence in 2014, seizing a computer hard drive. The domain name p2planet.net has been inactive for a decade. Legal actions against torrent site operators in Greece are rare, indicating a potential shift towards stricter enforcement of copyright laws. In 2019, a Greek court sentenced another individual to five years in prison for managing multiple pirate sites. Global trends show a decline in piracy, with visits to illegal sites projected to drop from 229 billion in 2023 to 216 billion in 2024.

Do I need an antivirus and a VPN?

Reliance on antivirus software for device protection is common, but certain threats, especially ransomware, can bypass even the best solutions. Cybercriminals have shifted tactics from encrypting data for ransom to exfiltrating sensitive information and threatening to leak it. The availability of ransomware kits and the use of AI by attackers have made cybercrime more accessible and targeted. Remote work environments increase vulnerabilities, as hackers exploit unsecured networks and personal devices. Antivirus software can help protect against malware and viruses, but built-in solutions often lack comprehensive security. A high-quality antivirus program can enhance protection through advanced features and AI. A Virtual Private Network (VPN) encrypts data and secures internet traffic, making it a valuable tool for cybersecurity. Implementing a VPN is cost-effective compared to potential data breach costs. Using both a VPN and antivirus software is essential for comprehensive coverage, as they address different security aspects. Businesses may need advanced endpoint protection solutions for heightened security, which continuously scans for suspicious behavior and integrates multiple security features. Despite these tools, proper personal practices and cybersecurity awareness are crucial to minimize vulnerabilities and human error, which is a leading cause of cyberattacks.

Key service for malware developers taken offline

The takedown of AVCheck, a major Counter Antivirus (CAV) service used by cybercriminals, disrupts their ability to test malware against antivirus detection, thereby hindering successful attacks. Matthijs Jaspers from the High Tech Crime Team highlighted that this operation is crucial in combating organized cybercrime, as it prevents early-stage criminal activities. The investigation revealed connections between AVCheck and other services like Cryptor.biz and Crypt.guru. Additionally, law enforcement has taken proactive measures, including deploying a fake login page to deter AVCheck users and collaborating with Project Melissa to target malware services. The need for coordinated efforts among various sectors is emphasized to effectively combat cybercrime.

International authorities dismantle AVCheck in cybercrime operation

International authorities have dismantled AVCheck, a platform used by cybercriminals to test malware against antivirus software. The website avcheck.net now displays a seizure notice from the US Department of Justice, FBI, US Secret Service, and Dutch police. AVCheck was one of the largest counter antivirus services globally, aiding cybercriminals in evaluating their malware's stealth capabilities. Investigators found links between AVCheck's administrators and crypting services like Cryptor.biz and Crypt.guru. Law enforcement had placed a fake login page on AVCheck to warn users about legal risks before its shutdown on May 27, 2025. Undercover agents confirmed the illegal nature of AVCheck through transactions and connections to ransomware attacks. The FBI has also warned about the Silent Ransom Group, which has targeted law firms in the US using social engineering tactics.
