https://bit.ly/47wzEM4 - 🔒 AhnLab Security Emergency response Center (ASEC) reports an ongoing campaign where Ddostf DDoS bot malware is targeting vulnerable MySQL servers. This campaign primarily affects servers running in Windows environments, where MySQL is less common than MS-SQL but still present. The majority of malware strains identified in these attacks are variants of Gh0st RAT, with AsyncRAT also being used in some instances. #Cybersecurity #MalwareAlert #MySQLServerProtection 💻 Ddostf, a DDoS bot first identified in 2016 and known for its capability to conduct Distributed Denial of Service attacks, has been observed being installed on these vulnerable servers. Unlike MS-SQL, which supports direct OS commands, MySQL uses a feature called User-defined Function (UDF) to allow command execution, which attackers exploit to deliver malicious commands. #DDoSAttack #ServerSecurity #CyberAttackTactics 🖥️ The UDF malware used in these attacks can download files and execute commands provided by threat actors. It's presumed that attackers utilize UDF's downloader() function to download Ddostf from an external source and then execute it using the cmdshelv() function. These attacks demonstrate the sophisticated methods used by cybercriminals to exploit database servers. #UDFExploit #CyberThreats #DatabaseSecurity 🤖 Analysis of the Ddostf DDoS Bot reveals that it operates in both ELF and PE formats, targeting Linux and Windows environments respectively. Upon execution, Ddostf copies itself under a random name and registers as a service. It then connects to a Command & Control (C&C) server and can execute various DDoS attack methods. #MalwareAnalysis #CommandControl #CyberDefense 🛡️ To protect against such attacks, administrators should use strong, periodically changed passwords and apply the latest patches to prevent vulnerability attacks. Security measures like firewalls are essential for externally accessible database servers. AhnLab MDS Sandbox detects Ddostf malware, offering a layer of protection against these threats.
