One of the most difficult obstacles to overcome in the quantum race will be the supply chain, given how diffuse it is, a top White House official said Wednesday.

“Supply chain is one of the biggest challenges in my mind, and really, the challenge with the quantum supply chain is that quantum is not defined by a single hardware platform,” said Brad Blakestad, director of the National Quantum Coordination Office within the White House Office of Science and Technology Policy.

“If you look at the quantum computing technologies, the quantum sensing technologies, the networking — those are all different,” he said in a webinar hosted by Inside Cybersecurity and USTelecom. “And even within computing, there’s seven different modalities that use completely different components. So we have this not just one monolithic supply chain, but just a bunch of different supply chains that are kind of intertwined in various ways.”

Blakestad made his remarks a little more than a month after President Donald Trump signed two executive orders on quantum computing. He referenced proposed ways to address the supply chain challenge in one of the orders.

“The other major issue or challenge that we face right now is that we’re on the cusp of quantum exploding from a commercialization perspective, but we’re not quite there yet,” he said. “So there’s not the funding, the revenue coming from large-scale quantum companies at this point to really make the supply chain as robust as you would want. So thinking about it from the government perspective, it’s just [that] there are too many places that I would want to bolster and not enough funding to do it.”

Blakestad touted steps to help that along such as the government buying widgets from a company that makes them to certain specifications, or prize challenges.

The quantum supply chain isn’t just diffuse in the United States, an International Institute for Strategic Studies policy paper noted Wednesday. It’s “inherently international: no single country dominates the supply chain, whether specialised materials, cryogenic equipment, hardware, software, fabrication or algorithms,” the authors, Dongyoun Cho and Maria Shagina, wrote.

And a March report from the Center for a New American Security identified strengthening the quantum supply chain as pivotal to the United States seizing the benefits of the technology, citing gaps in the U.S. supply chain and reliance on foreign suppliers such as China and Russia. 

Supply chain wasn’t the only obstacle Blakestad mentioned as looming large.

“The encryption challenge is a real challenge, and we want to make sure that we are aware of when quantum computers will ultimately get to a scale that they start having these sorts of implications and move as quickly as we can,” he said. “So, just by owning the technologies, by owning the workforce, by making the United States the place that people want to come to be on the cutting edge of this technology, I think that kind of addresses both of those issues, and that’s what makes it so critical.”

Another difficulty is measuring progress, Blakestad said: “It’s also very, very hard to benchmark, and to know that you’re actually doing what you’re supposed to, what you are intending to do.”

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.

Authorities arrested and unsealed charges against a Canadian man accused of running Kimwolf, one of the most far-reaching DDoS botnets on record, the Justice Department said Thursday.

Jacob Butler was arrested Wednesday in Ottawa, Canada, and awaits extradition to the United States where he is charged with aiding and abetting computer intrusions and, if convicted, faces up to 10 years in prison.

Investigators said the 23-year-old, also known as “Dort,” was a principal administrator of Kimwolf, a variant of the record-setting Aisuru DDoS botnet that spread like wildfire and eventually took over more than 2 million Android TV devices after its operators figured out how to abuse residential-proxy networks for local control.

Authorities in March seized infrastructure powering the Kimwolf, Aisuru, JackSkid and Mossad botnets, which hijacked a combined three million devices and launched more than 300,000 DDoS attacks collectively.

Kimwolf, which operated as a DDoS-for-hire service for other cybercriminals, initiated more than 25,000 attacks, resulting in network outages, disruptions and financial losses exceeding millions of dollars, officials said. Officials also said they found evidence linking Kimwolf to DDoS attacks targeting Department of Defense Information Network IP addresses.

“Kimwolf and the botnets associated with this operation have supported persistent corporate intrusion efforts and been used by a wide range of serious threat actors,” Zach Edwards, staff threat researcher at Infoblox, told CyberScoop.

Authorities searched Butler’s residence during the globally coordinated operation, but did not arrest him until Wednesday, roughly two months later. Officials filed a criminal complaint against Butler in the U.S. District Court for the District of Alaska in April, and unsealed the complaint following his arrest.

A special agent with the Defense Criminal Investigative Service confirmed Butler’s identity and involvement in the Kimwolf botnet after Butler used the same IP address to access multiple email accounts he controlled and Discord accounts linked to Kimwolf. 

“I have observed significant operational security lapses on Butler’s part resulting in patterns of overlapping IP usage among a Google account in Butler’s true name, other Google accounts that I believe to be controlled by Butler due to use of the same machine cookies, and Discord accounts which have been used in support of the KimWolf operation,” the special agent said in an affidavit. 

“The Discord accounts show patterns of overlapping IP usage with the KimWolf backend server. These IP addresses appear to be proxy or VPN IPs which were likely used by Butler in an unsuccessful attempt to evade law enforcement scrutiny. However, like many cybercriminals, Butler did not use proxy or VPN IP addresses exclusively,” the special agent added. 

Authorities described the botnet takedowns in March in nearly conclusive terms at the time, yet court records indicate the Kimwolf botnet is back in operation. 

“While today’s announcement is encouraging to see, there are still hundreds of millions of insecure IoT and network devices connected to sensitive government, corporate and home networks, and these remain a priority target for threat actors looking to build the next version of Kimwolf,” Edwards said.

“Until we find solutions to this underlying problem,” he added, “we’ll unfortunately continue to play Whac-A-Mole with botnet operators year after year.”
