Ransomware is a type of malicious software (malware) used by cyber criminals to encrypt data from a victim’s computer, rendering it inaccessible. It is typically spread through malicious links, phishing emails, or vulnerable software. Recently, two vulnerabilities, CVE-2023-24880 and CVE-2023-44698, have been exploited by cyber criminals to deliver Magniber Ransomware. Microsoft has already issued a patch for the first vulnerability, but for the second one, it seems like it hasn’t been fully covered yet. Moreover, Silicon Valley based Rubrik was also a victim of a ransomware attack, where the hackers exploited a vulnerability in Fortra GoAnwhere file sharing software.
To protect yourself from ransomware, it is important to regularly update your operating system and software, avoid clicking on malicious links, and use antivirus software. Additionally, it is important to create regular backups of your data and store them in a secure location to quickly recover in case of an attack. Lastly, always use strong passwords and be aware of phishing emails that look legitimate but are actually malicious.
