Readme is a type of malware that has been discovered to exploit and damage computer systems. It typically infiltrates systems through suspicious downloads, emails, or websites, often unbeknownst to the user. Once inside, it can steal personal information, disrupt operations, or hold data hostage for ransom. The malware is known to append extensions such as .keylock and .ELCTRONIC to files and drop ransom notes named README-id-[username].txt and README ELECTRONIC.txt respectively. Additionally, it publishes a ReadMe message in the web root directory, providing details necessary for a ransom payment. Upon completion of its main encryption job, it drops a ransom note titled “ReadMe”. The malware's activities are not limited to causing havoc on the infected system; it also utilizes various tools to enhance its effectiveness. For instance, it uses HookSignTool, a utility mentioned in the readme file on the HookSignTool Github. This tool can be used with any code signing utility, though the author specifically recommends the Chinese code signing utility "Digital Signature Tool for Asian Integrity". Moreover, it leverages ASN, which performs numerous functions without sending a single packet to the target, supplemented with "zmap" that scans the Web for specific ports running vulnerable services. The ReadMe malware is not just a threat but also an example of how cyber threats evolve and adapt. To counter these threats, it is crucial to update and patch affected products promptly. For instance, users are advised to refer to the appendix "Affected Products and Patch Information" in relevant documents to download the necessary patches and follow the instructions provided in the readme file within the patch installation package. Furthermore, a new addition to the docs/ directory contains README files that include tutorials on using Semgrep, applying custom rules from repositories, and an inventory table of custom rules. These guidelines have been updated in the README to help users protect their systems effectively.
