A cybersecurity working group at the G7 is urging governments to accelerate defenses against quantum computers that could break some existing forms of public key encryption.
The working group’s report, prepared in June at the G7 Summit in France, said organizations “can no longer afford to postpone” work transitioning critical systems and data to “post-quantum” forms of encryption.
“The quantum threat remains off the radar for many organizations and not properly resourced, with other security concerns taking precedence,” the working group report said. “Yet, a successful and collective transition to PQC can only be achieved if organizations understand that the quantum threat is an economic and business risk, and not merely a cryptographic risk.”
Instead, leaders in government and industry “must reframe the quantum threat from a distant future problem to a near-term threat that demands action across all sectors, not just critical infrastructure.”
The report acknowledged uncertain timelines for quantum computers, but identified that threats like harvesting current sensitive, encrypted data to decrypt it in the future do exist today.
The report also warned that quantum computers could compromise authentication and assurance mechanisms—by forging trusted data or stealing confirmation— jeopardizing secure communications and legal contracts.
The working group’s conclusions are largely in line with what governments have been recommending for years, urging industry to inventory and prioritize their critical systems and shift over to newer, “post-quantum cryptography” encryption algorithms.
These encryption algorithms, originally designed by independent cryptographers and vetted by the National Institute for Standards and Technology and National Security Agency, will be used to protect the government’s own systems and data from cybercriminals and foreign governments.
The Trump administration recently issued an executive order directing agencies to boost the domestic quantum industry and move up internal timelines for migrating to PQC encryption from 2035 to 2030. Google, a potential industry bellwether, and other companies have opted to move their own migration timelines to 2029.
But while that work has proceeded on schedule in some areas, like the federal government and the highly regulated financial sector, it has lagged in other industries where owners and operators feel they have more immediate concerns than quantum computers.
“We acknowledge that transitioning to PQC is not a problem for individual organizations to solve in isolation, but rather a collective transition that can only be achieved with early engagement, coordinated planning and informed decision making across the public and private sectors,” the working group wrote.
While often referred to as “Post-Quantum” encryption, the reality is more complex. Cryptographers believe the algorithms selected by NIST and NSA will stand up to attacks from a quantum computer, but since one doesn’t exist today, designing cryptographic protections against it requires some guesswork and mathematical estimation.
Estimates can be wrong, or overlook the entire cryptographic attack surface. Some NIST-selected algorithms have already been broken with traditional computers or AI. That’s why the agency backs multiple algorithms and concepts like “crypto-agility,” allowing organizations to quickly switch between them.
The G7 report was signed by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the UK’s National Cyber Security Centre (NCSC), The French Cybersecurity Agency (ANSSI), Germany’s Federal Office of Information Security (BSI), Canada’s Communications Security Establishment (CSE), Japan’s National Cybersecurity Office (NCO) and Italy’s National Cybersecurity Agency (ACN).

A Russian state-sponsored threat group has been stealing sensitive data from governments and commercial organizations since July 2025 via a novel exploit in popular Linux-based enterprise software, U.S. authorities and cyber officials from more than a dozen other countries warned in a joint cybersecurity advisory Thursday.
Laundry Bear’s most recent espionage campaign involves the exploitation of a zero-day vulnerability in Zimbra Collaboration Suite that wasn’t patched until November 2025, five months after attacks were well underway, officials said.
The exploit just requires a view — no clicks — and allows attackers to steal the previous 90 days’ worth of email, the account’s password, search history, the victim organization’s email directory, two-factor authentication tokens and other newly created passwords.
“The covert and persistent nature of this activity, along with the absence of any known financial extortion, almost certainly indicates this group’s involvement in espionage activities with Russian government backing,” officials wrote in the advisory.
“Additionally, extensive Ukrainian targeting, prior to use against U.S. and other NATO allies, outlines an increasing trend within Russian cyber threat groups to target Ukrainian users first—both as a priority target and as a testbench for malicious cyber techniques before broader global deployment.”
The state-sponsored espionage group, also known as Void Blizzard, has compromised governments and organizations in the defense, education, energy, law enforcement, media, finance, transportation and technology sectors.
Laundry Bear’s year-long campaign involving the exploitation of CVE-2025-66376 showcases more technical capabilities, including a custom JavaScript payload it delivers to targeted victims via phishing emails. The threat group could also likely adapt the novel data exfiltration and aggregation capability, dubbed “beehive,” to exploit other vulnerabilities, officials warned.
The defect’s medium-severity rating of 6.1 underscores the challenge defenders regularly confront in prioritizing patching schedules based on measure of severity alone.
The Russian state-supported group, which has been active since at least 2024, is still actively exploiting Zimbra Collaboration Suite instances that remain unpatched, officials said.
Authorities shared Thursday indicators of compromise, mitigation steps and urged organizations to update their vulnerable software.
“This campaign’s targeted victimology and limited exploitation capabilities likely indicate this group manually identifies and targets the victim organizations” by identifying organizations with public-facing infrastructure, officials wrote in the advisory.
Once a target is identified, Laundry Bear also likely compiles email addresses for users to target with the exploit via phishing emails. Officials did not identify specific victims or describe the volume of organizations already compromised.
The joint cybersecurity advisory was issued by the United States, Australia, Canada, New Zealand, the United Kingdom, Czech Republic, Denmark, Estonia, Finland, France, Italy, Moldova, the Netherlands, Poland, Spain and Sweden.

State and local officials and election security experts largely panned a Thursday night primetime speech by President Donald Trump, saying it was reflective of White House “desperation” to find any credible evidence to support their claims that U.S. elections have been rigged against the two-term president.
While the White House teased explosive new claims about the potential compromise of U.S. elections by China, Trump’s speech was a rehash of claims that both have no supporting evidence and have been repeatedly debunked when investigated.
David Becker, executive director of the Center for Election Innovation and Research and a former voting and civil rights attorney at the Department of Justice, said none of Trump’s claims or allegations were new or substantively different from previous theories he’s been espousing over the past six years.
“The White House promised a bombshell and they delivered a dud,” Becker said on a call with reporters Friday. “There was nothing that even calls into question past elections — certainly not the 2020 election.”
The administration declassified a huge tranche of documents from the intelligence agencies, and news outlets continue to sift through them, but thus far nothing has been found that remotely validates the administration’s claims about foreign interference from China costing Trump the 2020 election.
In fact, some of the most relevant documents found at this point have supported the opposite conclusion, with agencies assessing that while China engaged in influence campaigns around the election, it was not attempting to outright interfere with U.S. election infrastructure, hack voting machines or manipulate ballots.
John Solomon, a former journalist and opinion writer at The Hill brought in by the White House to lead the investigation, also told reporters Thursday that his search hasn’t turned up evidence that the 2020, 2022 or 2024 elections were affected by fraud.
The one new major claim by Trump — that the Department of Homeland Security determined hundreds of thousands of noncitizens were registered to vote across four states — is almost certainly false or overinflated, given that it contradicts post-election state audits that have routinely found single or double-digit numbers of noncitizens registered to vote within a single state across multiple elections.
Over the past six years, similar claims by GOP secretaries of state and political activists purporting to find mass numbers of noncitizens registered to vote have turned out to be grossly inflated due to shoddy data analysis, and the vast majority of cases involving “suspected noncitizens” turn out to be U.S. citizens who are legally registered to vote.
The White House has provided little to no information on the methodology used to flag and identify supposed noncitizen voters, other than alluding to the use of “commercial data” and federal databases. A federal court recently ordered DHS to dismantle the SAVE database, its primary database for verifying the citizenship status of U.S. voters, because it was unreliable and violated longstanding privacy laws.
Apart from DHS admitting its own data on citizenship is incomplete, Becker said using a list that relies on matching voter files with commercial data is not a reliable way of determining citizenship.
“It is impossible to take a public voter file with very little information that is uniquely identified, like a driver’s license number, and compare it to a commercial database and say for sure the Maria Rodriguez or the John Lee or the Shawn O’Hara you have on that is the same person,” he said.
Election officials also responded forcefully. Nevada Democratic Secretary of State Francisco Aguilar said that Trump has spent a decade attempting to manufacture a crisis around voter fraud and the president’s speech Thursday night was an extension of that effort.
“As Nevada’s chief elections officer, it’s my job to call balls and strikes — so when the President lies, I am obligated to call him out,” Aguilar said in a statement. “The facts have not changed: Nevada’s elections are among the safest, most secure and accessible in the nation.”
It’s not just Democrats that have objected to the administration’s efforts. GOP states have gone to court to block the Department of Justice from obtaining their voter data, and Idaho’s Republican secretary of state responded to a DOJ letter threatening prosecution of election officials as “not well met” and potentially illegal under state ethics laws.
Trump’s speech potentially casts additional light on recent White House decisions, such as firing all three commissioners on the Election Assistance Commission. The agency helps certify voting machines for security, and all three commissioners have served across administrations and maintain close relationships with state and local election officials.
Pamela Smith, CEO of the nonprofit Verified Voting, said that while the EAC can’t take certain actions that need commissioner approval, “critical functions like voting system testing and certification can continue under the existing framework and should not be affected.”
In 2020, Trump’s initial claims of widespread election fraud were undercut by leaders at the Cybersecurity and Infrastructure Security Agency, which said there was no evidence the election was compromised. The removal of EAC commissioners could represent an attempt to preempt any efforts to rebut or criticize White House claims that elections and voting machines have been compromised.
Some have worried that Trump could use the speech as a pretext to declare a national emergency or cancel elections.
Tom Lopach, CEO of the Voter Participation Center, said “you don’t dismantle election security infrastructure if you’re serious about protecting elections.”
“You dismantle it if you’re planning to claim, without evidence, that the system failed you,” he said.
While Becker takes Trump’s broadsides against state election authority seriously, he also said it’s important not to lose sight of the fact that, in his view, the administration is losing the argument across the board.
More than a dozen federal courts have unanimously rejected the federal government’s attempts to forcibly obtain state voter data, while other courts have rejected core pieces of his election-related executive orders. State officials have publicly — and at times, angrily — pushed back on the administration’s demands as blatant federal overreach.
Becker predicted that such an act would be quickly shot down by courts as well, noting that the U.S. has never canceled or postponed an election in its 250-year history, including when British troops were marauding on American soil during the War of 1812 or even at the height of the Civil War.
It’s important not to conflate the White House’s bluster and intentions with its actual authorities or capability to seize control of U.S. elections.
“This is what panic and desperation look like,” Becker said. “They’ve had 18 months in total control of the federal government and they have found nothing that would support President Trump’s lies about the 2020 election, and so they’re just trying to grab as much garbage as they can and throw it up against the wall, and it’s not sticking.”

Russian state-sponsored hackers are breaking into critical infrastructure around the world by exploiting poorly configured and vulnerable networking devices, authorities from the United States and 12 additional countries said in a joint cybersecurity advisory Monday.
Officials once again urged defenders to take more preventative measures to thwart attacks from the Russian Federal Security Service Center 16, which has been actively targeting critical infrastructure for more than a decade. The hackers are also tracked as Berserk Bear, Energetic Bear, Crouching Yeti, Dragonfly, Ghost Blizzard and Static Tundra.
“This is an ongoing issue that has impacted various U.S. and foreign networks across multiple sectors, including the defense industrial base, communications, energy, financial services, government facilities and health care sectors,” the National Security Agency said in a statement.
The state-sponsored attackers scan the internet for vulnerable routers using default or weak passwords, and have also exploited vulnerabilities in Cisco devices, Cisco’s Smart Install feature and web portals to take over network devices.
Two of the Cisco vulnerabilities exploited by the Russian FSB Center 16 hackers are quite old, including CVE-2008-4128 and CVE-2018-0171.
Officials shared technical details of the threat group’s activities and advised network defenders to disable Cisco Smart Install on all devices, use stronger modes of authentication and passwords, monitor for unusual credentials and logins using local accounts.
The joint advisory comes nearly a year after the FBI issued a similar alert about the same group targeting end-of-life networking devices running Cisco Smart Install.
On Monday, the European Union blamed Russia’s FSB Center 16 for a December 2025 attack on Poland’s energy grid. The United Kingdom, also on Monday, sanctioned 24 individuals and entities allegedly involved in various attacks attributed to Russian intelligence services.
“From directing criminals to targeting businesses, and striking Poland’s energy grid in the depths of winter, the Russian state is sinking to new lows in its attempts to undermine European security,” Yvette Cooper, foreign security of the United Kingdom, said in a statement.
Other countries behind the joint cybersecurity advisory include: Canada, Australia, New Zealand, Czech Republic, Denmark, Estonia, Finland, France, Italy, Poland and Sweden.
