Binance’s Android app is quietly running TikTok and WeChat SDKs alongside 13 other trackers

Security researchers have found that the Binance Android app includes SDKs from ByteDance and Tencent, along with 13 additional third-party trackers. This raises privacy concerns for users, as the TikTok SDK collects device fingerprints, behavioral signals, and potentially clipboard data, while the WeChat SDK adds functionalities not necessary for a financial trading platform. The incorporation of these SDKs could expose sensitive financial information. Under EU GDPR and FTC regulations, undisclosed telemetry in financial apps may be considered deceptive trade practices, potentially leading to regulatory repercussions for Binance. Users are advised to revoke permissions from the app or switch to the browser-based platform. The situation could prompt regulatory scrutiny and audits of cryptocurrency asset management apps.

Man admits to locking thousands of Windows devices in extortion plot

A former core infrastructure engineer, Daniel Rhyne, admitted to locking Windows administrators out of 254 servers during an extortion attempt against his employer in Somerset County, New Jersey. Rhyne accessed the company's network without authorization from November 9 to November 25, deleting network admin accounts and altering passwords for 13 domain admin accounts and 301 domain user accounts to "TheFr0zenCrew!". He also scheduled tasks to modify passwords for two local admin accounts affecting 3,284 workstations and planned to shut down random servers and workstations in December 2023. On November 25, he sent a ransom email demanding 20 bitcoin, claiming IT administrators were locked out and server backups erased. Forensic investigators found he used a concealed virtual machine to plan his actions. Rhyne was arrested on August 27 and faces charges related to hacking and extortion, with a potential maximum sentence of 15 years in prison.

Top 6 free crypto mining apps for Android in 2026

The appetite for free crypto mining applications on Android devices is increasing in 2026, with users seeking ways to earn Bitcoin and other cryptocurrencies without investing in expensive mining hardware. Mobile mining solutions now utilize cloud-based infrastructures and reward systems, allowing users to generate daily crypto income with minimal technical skills. Key mining applications include: 1. AngelBTC: Offers daily sign-in hashpower with structured mining contracts, emphasizing renewable energy sources. 2. CryptoTab Browser Lite: Allows passive Bitcoin mining through daily web browsing, with modest earnings dependent on user activity and referrals. 3. StormGain: Combines a trading platform with mining features, enabling easy activation and reward monitoring. 4. ECOS: A regulated cloud mining provider offering trial access and structured contracts for new users. 5. MinerGate Mobile Miner: Supports multi-currency mining from mobile devices, though profitability is low due to hardware limitations. 6. NiceHash: A marketplace for buying or selling mining power, aimed at experienced users. In 2026, Android mining apps are categorized into three types: cloud mining, on-device mining, and reward-based systems. The most effective model combines cloud mining with engagement-based entry mechanisms. Industry trends include a shift toward structured entry models, transparent contracts, and a focus on renewable energy. Users should be cautious of unrealistic profit claims, withdrawal restrictions, and the potential for simulated mining rather than actual hashpower.

What Is a Crypto Miner Virus?

A crypto miner virus, or cryptojacking malware, secretly uses a device’s CPU or GPU to mine cryptocurrency for an attacker, leading to increased electricity costs and potential hardware damage for the victim. It typically infects devices through phishing emails, pirated software, compromised websites, and malicious browser extensions. Monero is the preferred cryptocurrency for mining due to its efficiency on standard CPUs and privacy features. Signs of infection include overheating, high CPU usage, and increased electricity bills. Detection involves monitoring system performance and running antivirus scans. Prevention includes using antivirus software, keeping systems updated, and avoiding pirated software. Notable incidents include attacks on a European water utility and the Los Angeles Times website.

Quantum Computing Isn’t Just Coming for Bitcoin—It Threatens Messaging Apps Too

IBM researchers are collaborating with Signal and Threema to develop messaging systems resilient to quantum computing threats, prompted by concerns that quantum technology could compromise current encryption methods. IBM's report stresses the need to redesign messaging protocols in anticipation of potential quantum capabilities that could break existing encryption. Cryptography expert Ethan Heilman highlighted that encrypted messaging platforms face immediate risks from quantum threats, specifically through "store-and-forward attacks." Both Signal and Threema are enhancing their security measures; Signal is implementing upgrades like PQXDH and SPQR for post-quantum protection, while Threema is integrating the ML-KEM algorithm for quantum-safe encryption. Research indicated that adapting the Signal protocol for quantum safety may increase bandwidth requirements, necessitating a complete redesign for efficiency.

Valves faces $900 million lawsuit, accused of abusing its dominance in PC gaming to over-charge for games and DLC, as UK court says the case can continue

The UK Competition Appeal Tribunal has allowed a lawsuit against Valve, alleging that the company has used its market dominance to charge inflated prices for games and downloadable content (DLC). The lawsuit, set for 2024, seeks £656 million in damages, claiming that up to 14 million UK gamers may have overpaid between £22 and £44 since June 5, 2018. Vicki Shotbolt, an advocate for children's digital rights, is the proposed class representative for the case, which is part of her campaign "Steam You Owe Us." A judgment on January 26 confirmed the case can proceed to trial, but it does not indicate the merits of the claims. The tribunal's decision suggests there may be grounds to explore allegations of unfair pricing practices by Valve. Additionally, a UK court has ruled that in-game gold can be classified as "property," making it subject to theft laws.

Hackers Advertised VOID ‘AV Killer’ with Kernel-level Termination Claims

A new threat actor named Crypt4You is promoting a tool called VOID KILLER on underground forums and dark web marketplaces. VOID KILLER is designed as a kernel-level antivirus and endpoint detection response process killer, specifically engineered to bypass existing security defenses. It targets the core of operating systems to dismantle protective barriers, posing a significant challenge to contemporary defensive architectures. VOID KILLER can terminate Windows Defender and around fifty consumer-grade antivirus solutions without detection, utilizing polymorphic build techniques to evade signature-based detection systems. It features automatic User Account Control (UAC) bypass mechanisms and can inject any executable file, making it compatible with various malware families. Custom builds of VOID KILLER are priced at three hundred dollars, and payment is accepted in cryptocurrencies. Organizations using Windows Defender, consumer antivirus software, and advanced EDR solutions face increased risk exposure due to this tool.
