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.

Hackers Hit Android Users, Drain Bank Accounts Remotely Through 760 Apps: Report

Cybersecurity experts have identified over 760 malicious applications that exploit Near Field Communication (NFC) technology to target Android devices, compromising sensitive user data and financial information. These apps often disguise themselves as legitimate banking and government services, convincing users to set them as default NFC payment methods. Once installed, they can intercept critical information such as login credentials and card details, which is then transmitted to hackers via Telegram channels. The campaign, which began in April 2024, affects users in countries including Russia, Poland, the Czech Republic, Slovakia, and Brazil, impersonating banks like Santander and VTB. Stolen data is sent to over 70 command-and-control servers managed by automated Telegram bots.

Why Aren’t Antivirus Programs Enough To Protect Crypto?

Cryptocurrency has introduced a decentralized approach to financial transactions, but it faces significant security challenges, including vulnerability to cyberattacks, theft, and fraud. Traditional antivirus software has limitations, such as reliance on signature-based detection, which struggles against emerging and polymorphic malware. Behavioral detection methods also have shortcomings, as stealth malware can disguise itself and conditional activation can evade detection. Fileless malware techniques and human error, such as phishing and weak password hygiene, further complicate security. To enhance security, cryptocurrency users should adopt a multi-layered strategy that includes using hardware wallets for offline storage of private keys, implementing multi-factor authentication (MFA), and utilizing dedicated anti-malware tools. Safe browsing habits and regular software patches are also essential, along with securely backing up private keys.

Meta Rolls Out New Tools to Protect WhatsApp and Messenger Users from Scams

Meta has introduced new security tools for Messenger and WhatsApp to protect users from scams. WhatsApp will now provide warnings when users attempt to share screens with unknown contacts during video calls. On Messenger, a "Scam detection" feature can be enabled to notify users of suspicious messages from unknown sources. This detection operates on users' devices, maintaining end-to-end encryption, although messages sent for AI review will lose this status. If a scam is confirmed, users will receive information about common fraudulent schemes and options to block or report the account. Meta has also removed over 21,000 deceptive Facebook Pages and accounts and disrupted nearly 8 million scam-related accounts on Facebook and Instagram this year. Scams often involve cybercrime syndicates from Southeast Asia using psychological manipulation to lure victims into investment fraud through emotional connections.

Minecraft mods: When ‘hacking’ your game becomes a security risk

Minecraft and Roblox are popular platforms for creativity and community engagement among younger audiences, but they also attract cybercriminals who exploit players by disguising malware as mods, cheats, or automation tools. A mod, short for "modification," is a user-created software extension that alters gameplay in Minecraft, but these mods can be maliciously exploited. Recent threats include over 500 GitHub repositories distributing an infostealer disguised as Minecraft mods and attacks using popular modding platforms like Bukkit and CurseForge to spread malware. Attackers often present malware as essential mods, which can lead to harmful background processes once installed. Common types of malware masquerading as mods include Trojans, infostealers, ransomware, and cryptominers. To reduce risks, players should download mods from trusted platforms, verify developers' reputations, be cautious of unusual file types, and use security software to check downloads. If a suspicious mod is installed, players should delete it, run a full antimalware scan, reinstall Minecraft from the official website, change passwords, and consult cybersecurity professionals if needed. To stay safe while using mods, players should use non-administrator accounts, keep systems updated, maintain regular backups, and implement robust security measures.

Crooks exploit Meta malvertising to target Android users with Brokewell

Cybercriminals are using Meta's advertising platform to spread the Brokewell malware, targeting Android users through deceptive promotions, particularly fake TradingView Premium ads since July 2024. Over 75 counterfeit ads have been identified, leading users to download a trojanized .apk file from cloned websites. Once installed, the app requests accessibility permissions and disguises itself with fake update notifications, ultimately deploying Brokewell, a spyware and Remote Access Trojan (RAT) that conducts extensive surveillance and data theft, primarily targeting users in the European Union. Brokewell employs obfuscation techniques and native libraries to hide its code, featuring a JSON configuration for overlaying legitimate applications and a decrypted .dex file for its main payload. It communicates with command and control servers via Tor and WebSocket, enabling various espionage activities, including crypto theft, 2FA bypass, account takeover, surveillance, SMS interception, and remote control of the device. Experts recommend that users only install apps from official app stores, avoid suspicious ads, verify URLs before downloading software, and review app permissions carefully. The risks associated with compromised devices are significant, especially as mobile banking and cryptocurrency wallets become more common.
