Amnesia: What If a Messenger Was Designed to Forget?

In digital communication, traditional messaging platforms act as persistent archives of user data, including accounts, devices, contacts, and interactions, which can hinder the essence of communication. While end-to-end encryption enhances privacy, it does not eliminate data retention. Amnesia is a concept that proposes a messaging platform emphasizing temporary communication with no permanent accounts or conversation histories. The initial prototype allows users to create one-time sessions using QR codes, ensuring that all data is destroyed once the session ends. Each session generates unique identity keys, preventing credential reuse and session token theft. The system does not retain any conversation history, reinforcing the principle that once a session is terminated, the data is irretrievable. Amnesia's relay facilitates communication without retaining user accounts or histories, and its design minimizes durable information to reduce risks. The project is currently an architectural concept and an early prototype, not ready for production or sensitive communications.

Study of 281 Free Android VPN Apps Finds Traffic Leaks, Unencrypted Data, and Tracking

Researchers analyzed 281 popular free VPN applications on the Google Play Store and found significant privacy and security shortcomings. The study, conducted by teams from the University of Michigan, the University of New Mexico, and IIT Delhi using a framework called MVPNalyzer, revealed that flagged apps had over 2.4 billion downloads. Key findings included: - Five apps transmitted configuration files unencrypted, allowing attackers to intercept and modify them. - 29 apps allowed user traffic to leak outside the encrypted tunnel, with 24 leaking DNS traffic and six leaking full browsing traffic. - 169 apps made no effort to disguise their traffic, making it identifiable to network operators or government censors. - 76 apps transmitted the device's Advertising ID to advertisers, and over 80% contacted known advertising and tracking servers. - Only one of 108 OpenVPN configurations adhered to recommended security practices; 89% used a single authentication method, and nearly 20% employed outdated encryption techniques. - Many apps passed through Play Store checks without adequate scrutiny, with safety labels often serving as marketing tools rather than security indicators. These findings align with previous research highlighting similar issues in popular Android VPN apps. Users are advised to be cautious when selecting VPNs, prioritizing those with recent independent security audits.

7 Habits That Are More Important Than Using Antivirus on Your Phone

Antivirus software was once standard on personal computers, but modern smartphones have evolved with enhanced security measures from Apple and Google, making them less vulnerable to traditional malware. Smartphones isolate applications, allowing them only to access user-permitted information, and if a malicious app infiltrates, it faces significant challenges due to built-in defenses. Apple requires thorough vetting of apps through the App Store, which enhances security but limits antivirus capabilities. Android allows sideloading apps from outside the Google Play Store, which introduces risks but also includes built-in security features like Google Play Protect and regular updates. Despite these advancements, smartphones can still be compromised, and cybercriminals increasingly target user accounts through phishing tactics rather than malware. Security experts recommend focusing on phishing awareness, strong passwords, and two-factor authentication. For enhanced security, users should keep devices updated, download apps from official sources, review app permissions, use strong passwords, utilize a password manager, enable two-factor authentication, and be cautious with unexpected communications. While most users may not need antivirus apps, those who frequently sideload or download from unfamiliar sites may benefit from additional security tools.

Why Anti Malware and Antivirus Solutions still matter despite Google Play Protect

Google Play Protect is a security feature integrated within the Google Play Store that scans installed applications for malicious behavior, verifies apps before download, and can disable or remove harmful software. Its primary limitation is its focus on apps from the Google Play Store, leaving users who install APK files from third-party sources at risk. Modern cyber threats include phishing links, counterfeit login pages, and social engineering techniques, which Google Play Protect does not fully address. Dedicated antivirus applications offer real-time threat detection, privacy protection, and additional features such as monitoring excessive app permissions and dark web credential leaks. For business users, mobile security platforms provide advanced capabilities like enforcing corporate policies and detecting zero-day threats. While Google Play Protect is sufficient for many users, those handling sensitive information or seeking enhanced protection should consider additional antivirus solutions. Best practices for cybersecurity include downloading apps from trusted sources, keeping software updated, and using strong passwords.

Fake virus alerts are invading mobile games

Cybercriminals sometimes manage to buy advertising space and use it to defraud gamers. The iCloud storage scam is a well-known scam that claims you need to expand your storage or all your files will be deleted. Scammers also use fake warnings to trick users into clicking links or downloading harmful software. Fleeceware apps lure users in with short free trials that quickly convert into hidden subscription fees. The best response to these messages is to ignore them and use an up-to-date anti-malware solution on your devices.

New Rokarolla Android malware targets 217 banking, crypto apps

A new Android banking trojan named Rokarolla targets 217 banking and cryptocurrency applications and features 137 commands for malicious activities. It is distributed via deceptive websites posing as legitimate application sources and impersonates Google Play Protect to lure users into installing infected apps. Once installed, it seeks Accessibility service permissions and access to notifications, SMS, and calls. Rokarolla communicates with a command-and-control server, sending device profiles to generate unique identifiers for victims. Its primary goal is to steal financial information by using deceptive login overlays to capture sensitive data and maintain control over the device. The malware employs evasion tactics such as disabling Google Play Protect, hiding its icon, silencing notifications, and keeping the screen awake. It can steal SMS messages, extract contacts, capture keystrokes, record screen content, manipulate clipboard contents, block calls, and take screenshots. Zimperium confirms that Rokarolla is not found on Google Play, and users are advised to avoid downloading APK files from untrusted sources and to be cautious with Accessibility permissions.

50+ Samsung Galaxy Store apps spread phone malware

Samsung's Galaxy Store had over 50 applications that unknowingly distributed a hidden Android trojan named MagicAd, which has since been removed. Users who downloaded these apps may still have the malware on their devices, as it establishes persistent background services that remain after the app is uninstalled and hides its icon. Signs of infection include unsolicited ads, battery drain, and unexplained data usage. The malware evades detection by assessing its environment and concealing its core code in encrypted files. Developers rotated the infected apps to maintain persistence and generated revenue through fraudulent ad impressions. Users are advised to run security scans and consider a factory reset if symptoms persist, ensuring to back up important files without including app settings. No app store can guarantee the exclusion of all threats, so users should check ratings and download counts before installing applications.
