Anthropic has given the European Union’s cybersecurity authority access to its powerful Mythos artificial intelligence model after months of talks with officials in the bloc.

“Following our constructive engagement with Anthropic, we can confirm that the EU’s cybersecurity agency Enisa has been granted access to Mythos 5,” European Commission spokesperson Thomas Regnier said on Thursday.

A spokesperson for Enisa also confirmed that it has access to Anthropic’s Mythos 5 model and has been testing it this month.

It comes roughly four months after the commission—the EU’s executive arm—first said it was in discussions with the company over Mythos 5, which can spot vulnerabilities in computer code and has sparked national security concerns from officials on either side of the Atlantic. The company only released the model to around 50 companies and organizations including Amazon Web Services and JPMorgan Chase initially in April, before expanding its release to around 150 organizations in June.

Cyber officials had been in talks with Anthropic since May about testing Mythos 5, which resulted in months of back and forth between the two sides.

U.S. President Trump’s administration then moved to ban foreign entities from using Anthropic’s Fable 5 and Mythos 5 tools in June, prompting the company to shut off access altogether. The White House allowed the company to re-offer access to Mythos 5 to a limited group of companies and governments weeks later.

The EU’s cyber agency has also gained access to rival OpenAI’s GPT-5.6 Cyber and new GPT-6-Astra, the commission spokesperson said.

EU to Hold ChatGPT, Reddit, Roblox to Higher Standard of Scrutiny

The companies have until the end of the year to comply with the change

The European Union said OpenAI’s ChatGPT, Reddit and RobloxRBLX 4.35%increase; green up pointing triangle should be held to a higher standard of scrutiny under the bloc’s Digital Services Act as Brussels seeks to mitigate potential risks from their services and algorithmic systems for millions of users.

The European Commission, the EU’s executive arm, said it had designated ChatGPT as a very large online search engine and Reddit and Roblox as very large online platforms under the DSA because they counted at least 45 million average monthly users in the bloc.

They join ranks with heavyweights like Amazon.com, Apple, Alphabet’sGoogle, Meta Platforms, Microsoft and TikTok that have already earned such EU designations.

Under the DSA, online marketplaces, social networks, content-sharing platforms, app stores and online travel and accommodation platforms have obligations to ensure their products are safe or risk a fine of up to 6% of their annual revenue as well as periodic penalty payments.

However, those designated as very large online search engines and very large online platforms must comply with additional obligations to ensure their algorithmic systems can’t be misused to spread illegal content, influence elections or harm users, especially minors.

“These new designations mean that ChatGPT, Reddit and Roblox will now be held to a higher standard of scrutiny and accountability in the European Union, in line with their large impact on our citizens and society,” Henna Virkkunen, the commission’s top tech enforcer, said.

EU officials will gain additional powers to probe the functionalities behind ChatGPT, Reddit and Roblox and ensure they are in line with the DSA. The companies have until the end of the year to comply with their additional obligations.

Spokespeople for OpenAI and Reddit said the companies were preparing to meet the compliance requirements that come with the designation and would coordinate with EU officials. Joost Hagesteijn, Roblox’s General Manager for Europe, said in a statement that safety was foundational to the company and that it would continue to engage constructively with the commission.

The commission has earmarked 28 very large online platforms and search engines under the DSA so far and the latest additions show that EU officials remain undeterred in their efforts to scrutinize powerful companies despite complaints from U.S. President Trump that the bloc is unfairly targeting American companies.

News Corp, owner of Dow Jones Newswires and The Wall Street Journal, has a content-licensing partnership with OpenAI.

Russia Is Bombarding Europe With a New Wave of ‘Gray Zone’ Attacks

NATO countries see Moscow’s appetite for conflict increasing as it flounders against Ukraine

Russia has turned up the heat on Kyiv’s allies in Europe, with a string of so-called gray zone activities aimed at sowing fear, as it struggles to advance on the ground in Ukraine and faces increasingly damaging Ukrainian drone and missile attacks at home.

European authorities have linked Russia to a spate of drone incursions, acts of sabotage, cyberattacks and other hostile actions across the continent over recent months.

Leaders across the U.S.-led North Atlantic Treaty Organization say the moves are a worrying indication of Russia’s rising appetite for risk in Europe, as President Vladimir Putin seeks to curb flows of European aid to Ukraine and sow divisions among allies. 

Western officials say Russia could escalate its confrontation further and has already captured Ukrainian drones that it could use for potential false-flag attacks on NATO countries. Kremlin spokesman Dmitry Peskov has dismissed the reports, saying they are being used to justify European militarization against Russia.

In a sign of Washington’s concern, Central Intelligence Agency Director John Ratcliffe on Tuesday made a surprise trip to Moscow, in part to tell Putin’s government that the U.S. stands by its NATO allies, according to people familiar with the visit.

“Russia is looking for ways to reduce support among NATO countries for Ukraine and, one of the secondary effects they are also pursuing is spreading panic,” said Remigijus Bridikis, director of Lithuania’s civilian intelligence agency.

Incidents over recent weeks included three explosive drones discovered in or near a German airport, one of them beneath a Ukrainian cargo plane. Russian drones have repeatedly entered NATO airspace. One was recently shot down over Romania.

Dutch intelligence agencies warned that “Russian state actors are systematically conducting digital espionage” by hacking web-linked cameras to spy on aid to Ukraine. 

The tempo of documented Russia-backed incidents has increased from a maximum of around 10 in many months since 2024 to around 15 a month since April, according to Ukraine’s Sahaidachnyi Security Center, which tracks Russian gray zone activities in Europe. Sahaidachnyi analysts say trends can be difficult to discern because many incidents suspected of being linked to Russia aren’t included in their data.

The drumbeat of low-level aggression has accelerated as Russia’s war with Ukraine has entered a new and deadlier phase. Ukraine has carried out increasingly successful strikes on targets deep inside Russia, battering its oil and gas sector as well as other industries that feed Moscow’s war machine. The Kremlin is now doing the same to Ukraine—though the money and supplies feeding Kyiv’s front lines extend far into NATO territory.

European authorities have accused Russia of hiring local agents over Telegram and other social-media platforms to conduct sabotage, espionage and vandalism meant to stoke divisions. Estonia is investigating whether Russia-linked sabotage was behind the arson attack this month on a local defense company, Milrem Robotics, while recent explosions and fires at munitions facilities in Italy, Bulgaria and Finland have drawn suspicion of Russian involvement, even though authorities haven’t said they see evidence of that.

Whether Putin is behind all the mayhem or not, getting credit for it can play to Moscow’s advantage by boosting its reputation for influence and impact. Slovak police on Tuesday said they had thwarted an attempted attack on a drone factory by “three foreigners,” whose nationality they didn’t identify. Suspicions in the region quickly turned to Russian involvement.

Russia’s campaign may prompt worry among Europeans that they face personal danger as a result of their governments’ Ukraine policies. Another potential fear is that sending weapons to Ukraine depletes European arsenals, which might be needed to fight Russia—and if Moscow shows it poses a threat, the logic of not sending arms east increases.

Distinctions in motivation matter little to the Kremlin, analysts say. Russia’s approach to conflict, dating back to Soviet times, can blur lines between covert subversion and outright warfare.

New U.S. intelligence reports assess that Russia could try to test NATO’s resolve with a limited assault on a member country in the next few years, through steps potentially ranging from a cyberattack to a small-scale land incursion. NATO’s collective security is based on the founding principle that an attack on one member represents an attack on all.

Short of that, the Kremlin still gains from riling domestic politics ahead of coming local or national elections in NATO countries including Germany, France, Finland, Estonia and Poland. Poland is particularly prone to disruption because tensions with Ukrainian refugees have been mounting. 

“The primary interest is to change the status quo in Europe,” said Estonian lawmaker Marko Mihkelson. “It’s an extension of the election interference you’ve seen them try to carry out” in other countries, he said. Officials in the U.S., U.K., Hungary and Romania over recent years have accused Moscow of trying to skew national voting.

There is little evidence that the plan is working. The alliance’s easternmost members show some of the strongest support for maintaining military aid to Ukraine and boosting military spending at home.

Romania, which had a robust Russia-sympathetic electorate in the years immediately following Russia’s invasion, has seen popular sentiment harden against Moscow following a series of drone incursions. Three drones were shot down over Romania last month and a drone incursion in May started a fire on the roof of a residential building.

Romania expelled a Russian diplomat last month, and the Kremlin responded Thursday by kicking out a Romanian diplomat in Moscow.
