What is the Morris Worm?

In early November 1988, the first ever network attack on computers connected to the global network took place. Her culprit was Cornell University graduate student Robert Tappan Morris.

The program, written by Robert Morris, had a small dictionary of the most well-known passwords, which provided it with penetration of 10 percent of computers connected to ARPANET. Once on a foreign computer, the program first checked whether the same program was already installed here. If the computer was still “clean”, the program masked its presence in the system, read a file that contained information about users of the “occupied” system, forwarded this information to the author, and then Continue reading

Who invented the Ctrl-Alt-Del combination?

The orders were huge, the money from them went big. What is there to think about trifles, about some personal computers there! Is it possible to use them as smart terminals for mainframes? In 1975, the 5100 model computer was released, which was quite suitable for one person to work on it. It was a desktop, with a built-in black and white monitor, with a keyboard and a tape drive. A good candidate for personal computers, if not for the price – 20 thousand Continue reading
