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.

European governments sanctioned Russian individuals and organizations Monday over what they said was a years-long campaign of cyberespionage from Turla and other Russian government-led “destructive attacks” against the bloc.

Monday’s confrontation of Moscow included action from the European Union, its individual member governments and the United Kingdom. It mostly took aim at Center 16 of Russia’s Federal Security Service (FSB) over its control of the cyber threat group known by a list of names including Turla, Secret Blizzard and Waterbug.

“Cybercriminals, self-proclaimed hacktivists and private companies linked to Russia, including actors operating under its instructions, direction or control, have also carried out, enabled and facilitated a wide range of malicious activities,” European Union High Representative Kaja Kallas said in a statement.

The EU called out Russia for the Turla campaign that dated back to 2010 in France with targeting of the government there, and has also featured activity against Germany, Poland, Cyprus, the Netherlands, Austria, Slovakia, Romania and Finland. It made special mention of blaming the FSB for last December’s attacks on Poland’s energy grid, which left half a million people without heat.

In all, the European Union sanctioned nine Russian individuals and four entities. While the EU didn’t name them, Kallas’s statement said it also included officers of Russia’s Main Intelligence Directorate of the General Staff (GRU).

The United Kingdom’s cyber sanctions, the first it’s done in coordination with the EU, featured a longer list of 24 individuals and entities. The U.K. named GRU senior leadership figures Vyacheslav Stafeyev, Ivan Senin and Ivan Kasyanenko for their alleged hybrid cyberattacks in conjunction with cybercriminals and recruitment of hackers across Russian universities. The U.K. also sanctioned individuals behind Lumma Stealer, the target of an international takedown last year.

“These sanctions strike at the core of the cybercriminal networks propping up the Russian state’s aggression, and the UK and EU are sending a clear message that Russia cannot hide behind its use of these proxy groups,” Foreign Secretary, Yvette Cooper, said in a news release that mentioned “destructive attacks” by Russia. “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.”

At least two European governments, Germany and France, said they would be summoning Russia’s ambassadors in their nations over the attacks.

Also Monday, the European Union announced sanctions against the company behind Russia’s messaging app, Max, citing its use of surveillance features to clamp down on dissent. And separately, 13 nations including the United States issued a warning on Monday about Russian government hackers targeting routers to carry out critical infrastructure attacks.

Russia routinely denies allegations of responsibility for any malicious cyber activity.

China-aligned attackers broke into the networks of U.S. and Canadian universities to steal sensitive data and establish persistent access via webshells and backdoors, Proofpoint threat researchers said Tuesday. 

The espionage-motivated attacks targeted physics and engineering departments, focusing on administrators and professors with national security links or organizations researching astrophysics and particle physics.

Proofpoint identified less than 10 university victims and estimates a few dozen universities may be impacted, Greg Lesnewich, principal threat researcher at Proofpoint, told CyberScoop. The company first observed the campaign in May and believes the campaign is ongoing. 

“There is a high likelihood that many victims have not been made aware of this activity yet,” Lesnewich added.

Researchers traced the attacks to a pair of critical vulnerabilities in Roundcube, an open-source email client, that were exploited and chained together to steal credentials and gain long-term access.

The threat cluster, which Proofpoint tracks as UNK_MassTraction, exploited CVE-2024-42009 to execute JavaScript inside the victim’s browser, then exploited CVE-2025-49113 to gain a foothold in the mailserver. 

The initial exploit in the chain only requires a victim to open an email, and the attackers sent victims a series of generic lures to trigger the initial access.

Proofpoint attributes the campaign to a China-aligned cluster because the attackers used a known covert network used by multiple China-aligned threat groups, an infection chain leading to VShell and left Chinese language artifacts in the phishing emails. 

Researchers haven’t drawn any conclusions about why attackers targeted the universities and what they are seeking. 

“We do not have data to suggest what got stolen, as we only observe the initial inbound email attempt,” Lesnewich said. 

The engineering aspects do align with China’s strategic initiatives, he added. Google threat hunters recently spotted a Chinese state-sponsored espionage group that burrowed into systems for years, stealing data across academia, medicine, military, cybersecurity and foreign policy. 

“China-aligned adversaries have been targeting other types of edge devices such as routers and VPN concentrators for years with various exploits to create a foothold into a target network, not using email for delivery,” Lesnewich said. “This campaign flips that on its head, using email to deliver an exploit chain to compromise a mail server, instead of using email to deliver a credential harvesting URL or malware to target an end user, not a server.”

Google threat hunters spotted yet another Chinese state-sponsored espionage group that for years had burrowed into systems belonging to government and private organizations to steal data across academia, medicine, military, cybersecurity and foreign policy. 

Google Threat Intelligence Group discovered the previously unknown threat group UNC6508, which targeted organizations in the United States and Canada, in late 2025 but traced its earliest known compromise back to September 2023. 

The revelation mirrors an alarming pattern of Chinese espionage groups dropping backdoors into critical infrastructure to pre-position for potential sabotage, intercept research and steal data with national security implications. These groups working at the behest of China’s government, including UNC6508, operated in stealth for years before authorities or researchers discovered their activity.

“We don’t know the full extent or impact of the campaign,” Patrick Whitsell, senior security engineer at GTIG, told CyberScoop. Researchers said the threat group intruded a medical research university in September 2023, stole credentials and communications, and remained active on the institution’s systems through November 2025 when it was discovered.

Google said it confirmed multiple victims compromised with INFINITERED, a custom backdoor the threat group deployed on targeted networks to steal administrative credentials after it exploited externally facing REDCap (Research Electronic Data Capture) servers.

Researchers still don’t know how UNC6508 gained initial access to the REDCap servers. Google said the survey and database software, which was created at Vanderbilt University and issued multiple patches for critical remote-code execution vulnerabilities throughout 2023, is widely used across the medical research community. 

“Given the breadth of the threat actor’s intelligence collection criteria and their ability to remain undetected within compromised networks for more than a year, we assess the known victims likely represent only a fraction of a larger campaign,” Whitsell said. “We also assess that this highly capable threat actor will remain active and continue to be a threat to the defense, technology and medical industries for the foreseeable future.”

Google said the campaign targeted clinical providers, academic medical centers and U.S. military health institutions, demonstrating advanced capabilities from a threat group that doesn’t currently overlap with any other publicly known groups.

The threat group abused domain compliance rules to steal data, a technique that doesn’t rely on malware or living-off-the-land tools, and routed traffic through U.S.-based IPs to blend in with legitimate traffic, researchers said.

“We have some evidence to suggest this is a large threat group with multiple sub-teams, but this is not confirmed,” Whitsell said.

Like other previously identified China state-sponsored espionage groups, UNC6508 remains active.

Google said it disrupted some of UNC6508’s known infrastructure by disabling an Gmail account it used to exfiltrate data, notified the affected organizations and helped remediate compromises before it published research on UNC6508’s activities.

Whitsell said several unconfirmed instances of compromise remain under investigation.
