that could indicate a link to North Korea . Symantec and Kaspersky Lab each cited code that was previously used by a hacker collective known as the Lazarus Group , which was behind the high-profile 2014 hack of Sony that was also blamed on North Korea . But the security firms cautioned that it is too early to make any definitive conclusions , in part because the code could have been merely copied by someone else for use in the current event . The effects of the ransomware attackAttack.Ransomappeared to ease Monday , although thousands more computers , mostly in Asia , were hitAttack.Ransomas people signed in at work for the first time since the infections spread to 150 countries late last week . Health officials in Britain , where surgeries and doctors ' appointments in its national health care system had been severely impacted Friday , were still having problems Monday . But health minister Jeremy Hunt said it was `` encouraging '' that a second wave of attacks had not materialized . He said `` the level of criminal activity is at the lower end of the range that we had anticipated . '' In the United States , Tom Bossert , a homeland security adviser to President Donald Trump , told the ABC television network the global cybersecurity attack is something that `` for right now , we 've got under control . '' He told reporters at the White House that `` less than $ 70,000 '' has been paid as ransomAttack.Ransomto those carrying out the attacks . He urged all computer users to make sure they installVulnerability-related.PatchVulnerabilitysoftware patches to protect themselves against further cyberattacks . In the television interview , Bossert described the malware that paralyzed 200,000 computers running factories , banks , government agencies , hospitals and transportation systems across the globe as an `` extremely serious threat . '' Cybersecurity experts say the hackers behind the `` WannaCry '' ransomware , who demandedAttack.Ransom$ 300 paymentsAttack.Ransomto decrypt files locked by the malware , used a vulnerability that came from U.S. government documents leaked online . The attacks exploitedVulnerability-related.DiscoverVulnerabilityknown vulnerabilities in older Microsoft computer operating systems . During the weekend , Microsoft president Brad Smith said the clandestine U.S. National Security Agency had developed the code used in the attack . Bossert said `` criminals , '' not the U.S. government , are responsible for the attacks . Like Bossert , experts believe Microsoft 's security patch releasedVulnerability-related.PatchVulnerabilityin March should protect networks if companies and individual users install it . Russian President Vladimir Putin said his country had nothing to do with the attack and cited the Microsoft statement blaming the NSA for causing the worldwide cyberattack . `` A genie let out of a bottle of this kind , especially created by secret services , can then cause damage to its authors and creators , '' Putin said while attending an international summit in Beijing . He said that while there was `` no significant damage '' to Russian institutions from the cyberattack , the incident was `` worrisome . '' `` There is nothing good in this and calls for concern , '' he said . Even though there appeared to be a diminished number of attacks Monday , computer outages still affected segments of life across the globe , especially in Asia , where Friday 's attacks occurred after business hours . China China said 29,000 institutions had been affected , along with hundreds of thousands of devices . Japan 's computer emergency response team said 2,000 computers at 600 locations were affected there . Universities and other educational institutions appeared to be the hardest hit in China . China 's Xinhua News Agency said railway stations , mail delivery , gas stations , hospitals , office buildings , shopping malls and government services also were affected . Elsewhere , Britain said seven of the 47 trusts that run its national health care system were still affected , with some surgeries and outpatient appointments canceled as a result . In France , auto manufacturer Renault said one of its plants that employs 3,500 workers stayed shut Monday as technicians dealt with the aftermath of the Friday attacks . Security patches Computer security experts have assured individual computer users who have kept their operating systems updated that they are relatively safe , but urged companies and governments to make sure they applyVulnerability-related.PatchVulnerabilitysecurity patches or upgradeVulnerability-related.PatchVulnerabilityto newer systems .

WASHINGTON — President Donald Trump ’ s homeland security adviser said Monday that the malware that has infected 300,000 computers in 150 countries is “ in the wild , ” but so far has not infiltrated U.S. government systems . Tom Bossert , assistant to the president for homeland security and counterterrorism , said three variants of the malware have been discovered and the U.S. government was closely monitoring the situation with officials in Britain . “ Overall , the U.S. infection rate has been lower than many parts of the world , but we may still see significant impacts in additional networks as these malware attacks morph and change , ” Bossert told reporters at the White House . “ We had a small number of affected parties in the U.S. , including FedEx . As of today , no federal systems are affected. ” Computers across the world were locked up Friday and users ’ files held for ransomAttack.Ransomwhen dozens of countries were hitAttack.Ransomin a cyber-extortion attackAttack.Ransomthat targeted hospitals , companies and government agencies . Cybersecurity experts say the unknown hackers who launched the “ransomware” attacksAttack.Ransomused a hole in Microsoft software that was discovered by the National Security Agency and exposed when NSA documents were leakedAttack.Databreachonline . The Department of Homeland Security is taking the lead on the investigation in the United States . The Cyber Threat Intelligence Integration Center is keeping the U.S. government informed about classified information concerning the investigation , he said . If Americans follow the patching information issued by the FBI , Microsoft and the Homeland Security Department , they will be protected from the malware and the variants , Bossert said . “ While it would be satisfying to hold accountable those responsible for this hack — something that we are working on quite seriously — the worm is in the wild , so to speak at this point , and patching is the most important message as a result , ” he said . “ Despite appearing to be criminal activity intended to raise money , it appears that less than $ 70,000 has been paid in ransomsAttack.Ransomand we are not aware of paymentsAttack.Ransomthat have led to any data recovery. ” Neither the FBI or NSA would comment Monday . Trump signed an executive order on Friday aimed at boosting the nation ’ s cybersecurity , as well as building and maintaining “ a modern , secure , and more resilient executive branch IT architecture. ” “ The trend is going in the wrong direction in cyberspace , and it ’ s time to stop that trend and reverse it on behalf of the American people , ” Bossert said after that signing last week . “ We have seen increasing attacks from allies , adversaries , primarily nation-states , but also non-nation-state actors , and sitting by and doing nothing is no longer an option. ” Homeland Security Advisor Tom Bossert announces May 11 that Trump signed an executive order to bolster the government 's cyber security and protect the nation 's critical infrastructure from cyber attacks , during a news briefing at the White House in Washington , D.C .
