We know of victims who don’t use M.E.Doc and have no obvious connections to Ukraine. Yet they were infected during Tuesday’s outbreak. This mystery is one of the factors that have kept us from jumping on the conspiracy train. And we still don’t have answers here.

Plusieurs grands groupes français ont dû faire face au virus qui s’est diffusé très rapidement mardi.

In Kiev, the capital of Ukraine, A.T.M.s stopped working. About 80 miles away, workers were forced to manually monitor radiation at the old Chernobyl nuclear plant when their computers failed. And tech managers at companies around the world — from Maersk, the Danish shipping conglomerate, to Merck, the drug giant in the United States — were scrambling to respond. Even an Australian factory for the chocolate giant Cadbury was affected.

It was unclear who was behind this cyberattack, and the extent of its impact was still hard to gauge Tuesday. It started as an attack on Ukrainian government and business computer systems — an assault that appeared to have been intended to hit the day before a holiday marking the adoption in 1996 of Ukraine’s first Constitution after its break from the Soviet Union. The attack spread from there, causing collateral damage around the world.

A major ransomware attack has brought businesses to a close throughout Europe, in an infection reminiscent of last month’s WannaCry attack. The most severe damage is being reported by Ukrainian businesses, with systems compromised at Ukraine’s central bank, state telecom, municipal metro, and Kiev’s Boryspil Airport. Systems were also compromised at Ukraine’s Ukrenego electricity supplier, although a spokesperson said the power supply was unaffected by the attack.

The attack has even affected operations at the Chernobyl nuclear power plant, which has switched to manual radiation monitoring as a result of the attack. Infections have also been reported in more isolated devices like point-of-sale terminals and ATMs.

The virus has also spread internationally. The Danish shipping company Maersk has also reported systems down across multiple sites, including the company’s Russian logistics arm Damco. The virus also reached servers for the Russian oil company Rosneft, although it’s unclear how much damage was incurred. There have also been several recorded cases in the United States, including the pharmaceutical company Merck, a Pittsburgh-area hospital, and the US offices of law firm DLA Piper.
