Several US government agencies have been hit in a global hacking campaign that exploited a vulnerability in widely used to transfer files from one computer to another.

‘We are working urgently to understand impacts,’ said Eric Goldstein, the executive assistant director for cybersecurity of the US Cybersecurity and Infrastructure Security Agency (CISA).

The hackers exploited a vulnerability in a program called MOVEIt, but it is unclear if sensitive information was compromised or if government systems have been disrupted.

While CISA did not specify how many federal agencies have been hit, Goldstein said that his agency ‘is providing support to several federal agencies that have experienced intrusions.’ 

Thursday’s report from the comes as the US has been hit with major attacks over the past few months. 

In late May, the Russian-speaking gang of hackers known as CLOP began leveraging a new flaw, or exploit, discovered in a widely used file-transfer software known as MOVEit. The hackers seemed to penetrate as many vulnerable organizations as they could identify.

Progress Software, which owns MOVEit and distributes it as a ‘secure managed file transfer software,’ urged its customers to install updates to correct the flaw, alongside other security advice. 

Johns Hopkins University released a statement this week alerting patients, students and the public that ‘sensitive personal and financial information,’ including health billing records from the university’s well-regarded healthcare system may have been compromised in the attack.

CLOP claimed credit for similar assaults on state government systems in both Minnesota and Illinois, as well as on major international firms including British Airways and Shell.

The entire university system across the state of Georgia also reported that its dozens of state colleges and schools, including the 40,000-student University of Georgia, had been penetrated in the attack. University officials said they were still investigating the ‘scope and severity’ of the attack.

CLOP’s tell-tale ransomware packages first emerged in February of 2019, according to the U.S. Department of Health and Human Services’ Health Sector Cybersecurity Coordination Center.

The hacker group’s extortion attempts have occasionally been staggeringly lucrative, including payouts as high as $500 million.

Cybersecurity experts told CNN that, while CLOP was the first hacker group to make use of the MOVEit exploit, others may now have obtained the capabilities to launch copycat attacks, like those that hit US federal government agencies this week. 

The ransomware group set a deadline of this past Wednesday, telling its victims to begin paying up or risk the public release of their stolen data. 

The group also said that it would begin dropping names of their other alleged victims, but as of Thursday morning, no US federal agencies were listed.

House Administration Committee Chairman Rep. Bryan Steil of Wisconsin doubled down on a demand that Manhattan DA Alvin Bragg be investigated for seeking to ‘usurp’ federal jurisdiction in a probe of former President Donald Trump.

Steil, along with two other Republican committee chairmen, demanded Bragg provide information and testimony, and said he faced ‘political pressure from left-wing activists.’ 

The lawmakers also have threatened legislative action to protect former and current presidents from ‘politically-motivated prosecutions’ – prompting Bragg to accuse them of inappropriately seeking to interfere in an ongoing investigation.  

‘I think what is so essential is we make sure every American is treated equally under the law role for federal oversight when funds going to the D.A.,’ Steil told Fox News on Monday. ‘The concern is re-purposing federal funds to pursue a political agenda. That’s a question that the House of Representatives needs to know, and the American people deserve to know an answer to.’

His pushback was on the same day the Manhattan grand jury met amid Bragg’s probe of the ‘hush’ agreement former President Donald Trump reached with porn star Stormy Daniels. Former National Enquirer executive David Pecker left the courthouse Monday afternoon amid reports that a mystery witness was seen inside a car approaching the Manhattan criminal court.

Steil and his GOP allies have pointed to reports that Bragg may bring charges related to federal campaign finance laws. Former Trump fixer Michael Cohen, who was sentenced to three years in prison in connection with the matter, pleaded guilty to campaign finance violations related to the payments, which he facilitated using funds from a home loan. The federal charge might allow prosecutors to get around a statute of limitations hurdle on a matter that played out in the last weeks of the 2016 campaign.

He phrased many of his criticisms as questions, without outright leveling charges of misconduct.

Steil asked whether Bragg ‘is engaged with federal agencies, particularly the Department of Justice, and whether or not he is trying to usurp the federal law of enforcing federal law, in this case the federal election violations.’

‘Are they coordinating with federal agencies, including the DOJ?’ he asked.  

He also defended the request by Trump’s Republican allies in Congress to demand testimony from a local prosecutor before charges have yet been brought in a case. Grand juries are kept secret and prosecutors say they don’t discuss their investigations to protect the innocent.

‘There is a federal nexus, and he should answer the questions we presented to him,’ he said.

Bragg unloaded in his own statement, which followed a March 25 letter from Steil, Judiciary Chairman and Trump ally Rep. Jim Jordan, Oversight’s Chairman Rep. James Comer, who has been heading a probe of the Biden family including Joe Biden’s son Hunter.

‘This unprecedented inquiry by federal elected officials into an ongoing matter serves only to hinder, disrupt and undermine the legitimate work of our dedicated prosecutors,’ the Manhattan District Attorney tweeted last week. ‘As always, we continue to follow the facts and be guided by the rule of law in everything we do.’ 

The House Republican lawmakers also have trained their sights on two former prosecutors who resigned from the Manhattan DA’s office over handling his investigation into former President Trump.

Attorney Mark Pomerantz and Carey Dunne sought to prosecute Trump in 2022 and resigned after Bragg rejected their legal theories.

That came amid a lack of movement in what had been dubbed a ‘zombie’ case. 

The letter notes that the two ‘resigned from the office over Bragg’s initial reluctance to move forward with charges in 2022.’

‘Bragg is now attempting to ‘shoehorn’ the same case with identical facts into a new prosecution,’ said the letter.

Trump has repeatedly railed against Pomerantz, who wrote a book about the case against Trump.
