He later released a piece of software that neutralized Rensenware (by setting a custom score and injecting it into the game, satisfying the Rensenware program requirements) [4] [5] onto GitHub with an apology. [6] He also released a small part of the ransomware source code without the payload. [5]
The virus writes its own code into the host program. When the program runs, the written virus program is executed first, causing infection and damage. A worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the host program, but can run independently and actively carry out attacks ...
