How does it Operate?Īccording to the report, initial infection starts in a Linux process, ‘crontab’, which is a standard process responsible for periodically scheduling timed jobs in Unix-like systems. This malicious file accepts a specific password for any users, thus allowing the attackers to log in as any user in the machine. The malware replaces the system’s pam_unix.so file with its own malicious version. Moreover the analysts add that in addition to setting up ways to gain backdoor access to the targeted machine, Skidmap also creates another access point for its operators to gain access to the machine. The malicious Skidmap is dangerously advanced because it also has the ability to set up a secret master password that grants it access to any user account present in the compromised system. That is not where the malicious activity ends the aforementioned kernel-mode rootkits can further be used by the attackers to acquire unrestricted access to the infected system. Thus remaining undetectable by the infected system’s monitoring tools. While further explaining just how the malware keep itself to remain hidden, the analysts said that Skidmap does so by utilizing a rootkit, a program that is responsible for installing and executing code on a system without the consent or knowledge of the end user. What makes their recently found malware, dubbed ‘Skidmap’ interesting, is the way it loads malicious kernel modules to keep its cryptocurrency mining operations under the radar. They went on to explain that cryptocurrency-mining malware is still a prevalent problem in the crypto space and with time malware are evolving, courtesy the efforts of cyber security criminals. Threat analysts, Augusto Remillano II and Jakub Urbanec, revealed their findings to the public in a post on Trend Micro, which is a known security intelligence blog. Two threat analysts recently came across a new form of Linux malware, which mines cryptocurrency all the while managing to stay hidden. Learn how to update your antivirus strategy.Calling the crypto community! There’s a new threat in town that puts crypto assets in danger. Today's antivirus products are not enough to protect against advanced cyber threats. Once the threat is identified, you must remove the malware from your network. In order to remove malware, you must be able to identify malicious actors quickly. You must have defenses that provide significant visibility and breach detection. ![]() Malware will inevitably penetrate your network. Sufficient advanced malware protection requires multiple layers of safeguards along with high-level network visibility and intelligence. As a result, it is crucial to deploy technologies that continually monitor and detect malware that has evaded perimeter defenses. Some advanced malware, however, will eventually make their way into your network. By securing the perimeter, businesses assume they are safe. Typically, businesses focus on preventative tools to stop breaches. How do I protect my network against malware?
