HONG KONG: A cybersecurity researcher appears to have discovered a “kill switch” that can prevent the spread of the WannaCry ransomware — for now — that has caused the cyberattacks wreaking havoc globally, they told AFP on Saturday.
The researcher, tweeting as @MalwareTechBlog, said the discovery was accidental, but that registering a domain name used by the malware stops it from spreading.
“Essentially they relied on a domain not being registered and by registering it, we stopped their malware spreading,” @MalwareTechBlog told AFP in a private message on Twitter.
The researcher warned however that people “need to update their systems ASAP” to avoid attack.
“The crisis isn’t over, they can always change the code and try again,” @MalwareTechBlog said.
Friday’s wave of cyberattacks, which affected dozens of countries, apparently exploited a flaw exposed in documents leaked from the US National Security Agency.
The attacks used a technique known as ransomware that locks users’ files unless they pay the attackers a designated sum in the virtual currency Bitcoin.
Affected by the onslaught were computer networks at hospitals in Britain, Russia’s interior ministry, the Spanish telecom giant Telefonica and the US delivery firm FedEx and many other organizations.
“I will confess that I was unaware registering the domain would stop the malware until after I registered it, so initially it was accidental,” @MalwareTechBlog tweeted.
Unfortunately, however, computers already affected will not be helped by the solution.
“So long as the domain isn’t revoked, this particular strain will no longer cause harm, but patch your systems ASAP as they will try again.”
The malware’s name is WCry, but analysts were also using variants such as WannaCry.
Forcepoint Security Labs said in a Friday statement that the attack had “global scope” and was affecting networks in Australia, Belgium, France, Germany, Italy and Mexico.
In the United States, FedEx acknowledged it had been hit by malware and was “implementing remediation steps as quickly as possible.”
Also badly hit was Britain’s National Health Service, which declared a “major incident” after the attack, which forced some hospitals to divert ambulances and scrap operations.
Pictures posted on social media showed screens of NHS computers with images demanding payment of $300 (275 euros) in Bitcoin, saying: “Ooops, your files have been encrypted!“
It demands payment in three days or the price is doubled, and if none is received in seven days, the files will be deleted, according to the screen message.
A hacking group called Shadow Brokers released the malware in April claiming to have discovered the flaw from the NSA, according to Kaspersky Lab, a Russian cybersecurity provider.
Kaspersky researcher Costin Raiu cited 45,000 attacks in 74 countries as of Friday evening.

Minnesota gears up for anti-immigration enforcement protest Friday despite dangerous cold
MINNEAPOLIS: A vast network of labor unions, progressive organizations and clergy has been urging Minnesotans to stay away from work, school and stores Friday to protest against immigration enforcement in the state.
“We really, really want I.C.E. to leave Minnesota, and they’re not going to leave Minnesota unless there’s a ton of pressure on them,” said Kate Havelin of Indivisible Twin Cities, one of the more than 100 groups that is mobilizing. “They shouldn’t be roaming any streets in our country just the way they are now.”
The Twin Cities of Minneapolis and St. Paul have seen daily protests since Renee Good was fatally shot by a US Immigration and Customs Enforcement officer during an operation on Jan. 7. Federal law enforcement officers have surged in the area for weeks and have repeatedly squared off with community members and activists who track their movements online and in streets.
On Thursday, a prominent civil rights attorney and at least two other people involved in an anti-immigration enforcement protest that disrupted a Sunday service at a Minnesota church were arrested.
Vice President JD Vance visited Minneapolis to meet with ICE officials. He said repeatedly that he believed the fraught situation in Minneapolis would improve upon better cooperation from state and local officials, and he encouraged protests to remain peaceful.
Friday’s mobilization was planned as the largest coordinated protest action to date, including a march in downtown Minneapolis despite dangerously cold temperatures that the National Weather Service forecast in the single to double digits below zero (-20 to -30 degrees Celsius).
While organizations have asked participants to prepare for the cold, Havelin compared the presence of immigration enforcement to just such winter weather warnings.
“Minnesotans understand that when we’re in a snow emergency … we all have to respond and it makes us do things differently,” she said. “And what’s happening with ICE in our community, in our state, means that we can’t respond as business as usual.”
More than a hundred small businesses in the Twin Cities, largely coffee shops and restaurants, said they would close in solidarity or donate part of their profits, organizers said.
Ethnic businesses especially have lost sales during enforcement surges as both workers and customers stay away fearing they would be detained.
But some are deciding to close anyway, preferring to take a stance in solidarity rather than the “unscheduled interruption” of having agents apprehend staff, said Luis Argueta of Unidos MN, a civil rights group.
Many schools were planning to be closed for a variety of reasons. The University of Minnesota, which has about 50,000 students enrolled, said there would be no in-person classes because of the extreme cold warning, and the St. Paul public school district said there would no classes for the same reason. Minneapolis Public Schools were also scheduled to be closed Friday “for a teacher record keeping day.”
Clergy planned to join the march as well as hold prayer services and fasting, according to a delegation of representatives of faith traditions ranging from Buddhist to Jewish, Lutheran to Muslim.
Bishop Dwayne Royster, leader of the progressive organization Faith in Action, arrived in Minnesota on Wednesday from Washington, D.C.
“We want ICE out of Minnesota,” he said. “We want them out of all the cities around the country where they’re exercising extreme overreach.”
Royster said at least 50 of his network’s faith-based organizers from around the US were joining in the protest.
About 10 faith leaders were planning to travel to Minnesota from Los Angeles while others from the same group planned a solidarity rally in California, said one of the organizers there.
“It was a very harrowing experience,” said the Rev. Jennifer Gutierrez of the large enforcement operation in Los Angeles last year. “We believe God is on the side of migrants.”
