Just over ten years ago, a unique pressure of malware blitzed the internet so swiftly that it shocked cybersecurity experts international. Known as Conficker, it turned into and remains the most continual laptop trojan horse ever visible, linking computer systems with Microsoft running systems globally, tens of millions of them, to create a sizeable illicit botnet, in effect, a black-marketplace supercomputer that a whole lot electricity controlled by using its unknown maker posed an existential danger not just to any enterprise connected to the net, but to the internet itself.
Botnets, networks of secretly related non-public computer systems managed via an unseen hand, have released some of the most notorious committed denial of provider assaults, flooding web sites with such a lot of facts requests that they crash. A 2012 attack all however shut down online operations at essential banking establishments. They additionally spread malware. Botnets were in the back of the WannaCry ransomware attack of 2017 which infected an expected 200,000 computers in 150 international locations and crippled laptop networks at National Health Service hospitals in England and Scotland.
A cyberweapon known as EternalBlue, stolen in 2017 from the National Security Agency’s secret labs, has been used to attack the networks of entire towns — Baltimore is still struggling to unfastened hundreds of municipal computer systems inflamed only remaining month. Botnets also enabled Russia’s meddling within the presidential election in 2016, sending hundreds of thousands of social media users fake testimonies.
Conficker’s botnet becomes easily capable of launching any of the above — and a way worse. At its top, when it consisted of at least 10 million people IP addresses, there have been few laptop networks within the international at ease enough to face up to an assault from it. And but it became used only as soon as, to spread pretty minor stress of “scareware” meant to frighten unsuspecting customers into downloading faux antivirus software program. That attack becomes exceptionally pedestrian, like taking a Formula One racecar for a gradual ride across the block. Surely something bigger changed into coming.

But it in no way did. Why? Who created Conficker, and why trouble if they had been now not going to use it?
Today, thanks to excellent sleuthing with the aid of the F.B.I. And a number of the world’s choicest cybersecurity professionals, there are answers to these questions. They offer an unsettling reminder of the splendid sophistication of a growing community of cybercriminals and nation states — and the vulnerability of no longer just our computers, however the net itself.
Fear of Conficker — the name was coined by means of Microsoft programmers combining “con,” from the call TrafficConverter.Biz, the website used for the worm’s joy ride, with a German expletive — peaked on April 1, 2009, while a new, more significant virulent pressure that might spread directly from computer to computer without any movement through customers, was programmed to activate.
This new generation caused frightening headlines and top-time TV warnings — CBS’s “60 Minutes” known as Conficker “one of the most dangerous threats ever.” Shawn Henry, assistant director of the F.B.I.’s cyber division, said its potential for harm changed into as exceptional as “a weapon of mass destruction or a bomb in certainly one of our major cities.”
