Unheard stories: The first computer virus

Brain is the first computer virus (released in its first form in 1986) written by two brothers by Basit Farooq Alvi and Amjad Farooq Alvi. It infects computers by replacing the boot sector of a floppy disk with a copy of the virus. Back in those days there was no portable USB sticks and Internet was not common so floppy disk was the main mechanism for transferring data from one computer to another. Although a virus, Brain did not steal personal information or cause damage to the infected hosts. The main intention of the authors was to prove how vulnerable computers were back then. What made it so distinctively special was that it came with a message that traces back to the author with contact information including three phone numbers and the full address. In 2011, 25 years after Brain was released, Mikko Hyppönen travelled to Pakistan to interview Amjad for a documentary. He came to the address, locked on the door, and greeting him at the opening door were Basit and Amjad. The brothers are still in business in Pakistan with a company called Brain Telecommunication Limited. Following is the message found with Brain.
