Hoy, hace un año...

365 days ago we were talking about a worm’s birthday: Conficker. It has been active for eight years now and it still installed on thousands of computers, without the owners suspecting a thing. The peculiarity of this virus is that it can adapt to the environment, camouflage and evolve, transforming itself into new variants. Designed to attack Microsoft Windows systems, it has spread in 190 countries and has infected more than 11 million devices.
As explained on Welivesecurity website, the worm takes advantage of an old vulnerability and can guess passwords and hijack computers with the aim of creating a botnet. Although a good antivirus should be able to locate and remove it, today, the worm is still infecting other computers. It is believed that cybercriminals who launched it, abandoned their activities in 2009, but the bug is still among the most detected malicious codes in the world. Will it be waiting in the shade to attack?
Also lurking, hidden in another file, we can run into a ransomware, a malicious computer program that can encrypt our operating system files and force us to pay a ransom if we want to recover them. This type of virus affected the website of Reader’s Digest magazine, installing a “cocktail” of malware. First, the Pony virus steals all usernames and passwords. Later, the Angler kit exploit looks for security holes in the computer and, finally, CryptoWall program encrypts all files. This is teamwork!
In the Artic, Scully and Mulder discovered that if they wanted to kill the alien worm, they had to confront it with another of its kind. In their territorial struggle, the two parasites ended up killing each other. That was the only way to kill them. That worked very well in the fiction. However, infecting the same computer with another virus may not be the best idea. We have already seen they know how to work as a team.
