Gobruterforcer botnet targets Linux servers with brute-force attacks

A new botnet known as GoBruteforcer has emerged, focusing on brute-force attacks against Linux servers. The threat was reported by IT Security News on January 12, 2026. Details highlight the botnet's specific targeting of these systems.

The GoBruteforcer botnet has been identified as a new cybersecurity threat primarily aimed at Linux servers through brute-force attack methods. According to a report from IT Security News, published on January 12, 2026, at 17:32:04 UTC, this botnet poses risks to server security by attempting unauthorized access via repeated password guessing techniques.

Brute-force attacks, as the name suggests, involve systematically trying multiple combinations to breach login credentials, making Linux servers particularly vulnerable due to their widespread use in hosting and cloud environments. The report underscores the need for server administrators to strengthen authentication measures, such as implementing multi-factor authentication and monitoring for unusual login attempts.

While specific details on the botnet's origin, scale, or affected regions remain limited in the initial coverage, the emergence of GoBruteforcer adds to ongoing concerns about evolving malware targeting open-source systems. IT Security News encourages readers to review the full article for protective strategies against such threats.

The Qilin ransomware group, also known as Agenda, has developed a hybrid attack using Linux payloads on Windows hosts to evade detection. By abusing legitimate remote management tools and exploiting vulnerable drivers, attackers disable defenses and target backups. This cross-platform tactic highlights evolving ransomware sophistication.

A Go-based botnet known as GoBruteforcer is scanning and compromising Linux servers globally by brute-forcing weak passwords on exposed services like FTP, MySQL, and PostgreSQL. Check Point Research has identified a 2025 variant that has infected tens of thousands of machines, putting over 50,000 internet-facing servers at risk. The attacks exploit common defaults from AI-generated configurations and legacy setups.

The pro-Russia hacktivist group CyberVolk has reemerged with a new ransomware-as-a-service platform called VolkLocker, supporting both Linux and Windows systems. First documented in 2024 by SentinelOne, the group returned after a period of inactivity caused by Telegram bans. Despite advanced automation via Telegram bots, the malware features significant encryption flaws that could allow victims to recover files without payment.

A critical vulnerability in React Server Components, known as React2Shell and tracked as CVE-2025-55182, is being actively exploited to deploy a new Linux backdoor called PeerBlight. This malware turns compromised servers into covert proxy and command-and-control nodes. Attackers use a single crafted HTTP request to execute arbitrary code on vulnerable Next.js and React applications.
