Bitcoin stealer malware found in official printer drivers

Procolored, a printer manufacturer based in Shenzhen, has been accused of distributing malware designed to steal Bitcoin through its printer drivers. The malware, embedded in USB drivers, has reportedly stolen approximately 9.3 BTC, valued at over 3,000. A backdoor program in the compromised drivers can hijack wallet addresses copied to the clipboard. Users are advised to conduct system scans and consider a complete system reset. The issue was first highlighted by YouTuber Cameron Coward, whose antivirus software flagged the malware. Procolored denied the allegations but later acknowledged the problem, stating they removed the infected drivers and attributed the malware to a supply chain compromise. Cybersecurity firm G-Data confirmed the presence of two types of malware in the drivers.

Thousands of PostgreSQL servers are being hijacked to mine crypto

Researchers at Wiz have identified a cryptojacking campaign by a group called JINX-0126, targeting over 1,500 misconfigured PostgreSQL servers by exploiting weak login credentials. The attackers deploy the XMRig-C3 miner to mine Monero, consuming nearly all computing resources and increasing electricity usage for victims. Each compromised device is assigned a unique mining worker for tracking. The campaign has evolved to include defensive measures and fileless deployment to evade detection. Nearly 90% of cloud environments host PostgreSQL instances, with about one-third publicly accessible, highlighting security vulnerabilities.

LCRYX Ransomware Attacks Windows Machines by Blocking Registry Editor and Task Manager

LCRYX ransomware, a VBScript-based threat, re-emerged in February 2025 after first appearing in November 2024. It encrypts files with the .lcryx extension and demands a ransom of 0 in Bitcoin for decryption. The ransomware operates with administrative privileges, disables essential system tools like Task Manager and Command Prompt, and restricts access to the Control Panel. It prevents the execution of diagnostic tools and disables inactivity timeouts. LCRYX ensures persistence by modifying registry settings and remapping keyboard keys. It uses a combination of Caesar cipher and XOR encryption techniques, eliminates backups, and makes recovery nearly impossible. The malware terminates essential processes, overwrites the Master Boot Record, and disables real-time monitoring features of antivirus solutions. After encryption, it generates a ransom note directing victims to a payment website. Some variants display pop-ups revealing the victim’s IP address or launch unrelated applications. Users are advised to implement comprehensive security solutions and maintain regular backups.

Antivirus Software: Annoying but Necessary

Computer viruses and antivirus software have been connected since the early days of the Internet, with McAfee antivirus emerging in 1987. Nearly every computer today uses some form of antivirus software. Paul A. Gagniuc, a professor at the University Politehnica of Bucharest, published a book titled "Antivirus Engines: From Methods to Innovations, Design, and Applications" in October, focusing on malware and antivirus development. Gagniuc began exploring coding and antivirus development in his childhood, creating Scut Antivirus between 2006 and 2008, which was designed to be fast and resource-efficient. The detection process for antivirus software involves cataloging snippets of virus code, with the Aho-Corasick algorithm allowing rapid checks against suspected files. The introduction of Bitcoin in 2009 significantly changed the malware landscape, enabling anonymous operations for hackers. Gagniuc expresses concerns about a decline in technical knowledge among young engineers since 2008, as many focus on high-level programming languages, potentially leading to a de-professionalization in technology. His book aims to address this knowledge gap and contribute to a broader understanding of the field.
