The text you provided appears to be a collection of random statements and links, but it does not appear to be a coherent article or discussion about ransomware or North Korea's involvement in cybercrime.

However, if we extract the relevant information from the text, we can see that:

* The most recent Medusa ransomware attacks are believed to be the work of Lazarus Group, a cybersecurity threat group associated with North Korea. * The malware tools used in these attacks include a custom backdoor and loader called Comebacker, which is exclusively associated with Lazarus Group. * The switch to Medusa demonstrates that North Korea's involvement in cybercrime continues unabated.

If you are looking for information on ransomware or North Korea's involvement in cybercrime, I would recommend searching for reputable sources such as news articles or official reports from cybersecurity organizations.
