Arla Foods has confirmed to BleepingComputer that it was targeted by a cyberattack that has disrupted its production operations.
The Danish food giant clarified that the attack only affected its production unit in Upahl, Germany, though it expects this will result in product delivery delays or even cancellations.
"We can confirm that we have identified suspicious activity at our dairy site in Upahl that impacted the local IT network," stated an Arla spokesperson.
"Due to the safety measures initiated as a result of the incident, production was temporarily affected."
Arla Foods is an international dairy producer and a farmer-owned cooperative with 7,600 members. It employs 23,000 people in 39 countries.
The firm has an annual revenue of €13.8 billion ($15.5 billion), and its products, including the brands Arla, Lurpak, Puck, Castello, and Starbucks, are sold in 140 countries worldwide.
The company told BleepingComputer that it is currently working to resume operations at the impacted facility, which should bring results before the end of the week.
"Since then, we've been working diligently to restore full operations. We expect to return to normal operations at the site in the next few days. Production at other Arla sites is not affected."
Considering that the first reports about a disruption at Arla's production operations surfaced on Friday, it is bound to cause shortages in some cases.
"We have informed our affected customers about possible delivery delays and cancellations," explained Arla's spokesperson.
BleepingComputer has asked the firm if the attack involved data theft or encryption, both staples of a ransomware attack, but Arla declined to share any additional information at this time.
Meanwhile, there have been no announcements about Arla on ransomware extortion portals, so the type of attack and the perpetrators remain unknown.
Microsoft’s head of security for AI, Neta Haiby, accidentally revealed confidential messages about Walmart’s use of Microsoft’s AI tools during a Build talk that was disrupted by protesters.
The Build livestream was muted and the camera pointed down, but the session resumed moments later after the protesters were escorted out. In the aftermath, Haiby then accidentally switched to Microsoft Teams while sharing her screen, revealing confidential internal messages about Walmart’s upcoming use of Microsoft’s Entra and AI gateway services.
Haiby was co-hosting a Build session on best security practices for AI, alongside Sarah Bird, Microsoft’s head of responsible AI, when two former Microsoft employees disrupted the talk to protest against the company’s cloud contracts with the Israeli government.
“Sarah, you are whitewashing the crimes of Microsoft in Palestine, how dare you talk about responsible AI when Microsoft is fueling the genocide in Palestine,” shouted Hossam Nasr, an organizer with the protest group No Azure for Apartheid, and a former Microsoft employee who was fired for holding a vigil outside Microsoft’s headquarters for Palestinians killed in Gaza.
Walmart is one of Microsoft’s biggest corporate customers, and already uses the company’s Azure OpenAI service for some of its AI work. “Walmart is ready to rock and roll with Entra Web and AI Gateway,” says one of Microsoft’s cloud solution architects in the Teams messages. The chat session also quoted a Walmart AI engineer, saying: “Microsoft is WAY ahead of Google with AI security. We are excited to go down this path with you.”
Akamai researcher Yuval Gordon discovered a privilege escalation vulnerability in Windows Server 2025 that allows attackers to compromise any user in Active Directory (AD).
The attack exploits the delegated Managed Service Account (dMSA) feature that was introduced in Windows Server 2025, works with the default configuration, and is trivial to implement.
This issue likely affects most organizations that rely on AD. In 91% of the environments we examined, we found users outside the domain admins group that had the required permissions to perform this attack.
Although Microsoft states they plan to fix this issue in the future, a patch is not currently available. Therefore, organizations need to take other proactive measures to reduce their exposure to this attack. Microsoft has reviewed our findings and approved the publication of this information.
In this blog post, we provide full details of the attack, as well as detection and mitigation strategies.
Une base de données contenant plus de 184 millions de logins et mots de passe uniques a été découverte en libre accès sur Internet. Derrière cette fuite massive, des identifiants liés à des services grand public, des comptes bancaires, des adresses gouvernementales… et aucun moyen d’en retracer l’origine.
Début mai, le chercheur Jeremiah Fowler a découvert une base de données Elastic non protégée contenant plus de 184 millions de logins et mots de passe uniques. Poids total de cette énorme fuite : 47,42 Go. L’ensemble était hébergé sur les serveurs du fournisseur World Host Group, sans mot de passe ni chiffrement, et donc librement accessible à quiconque connaissait son adresse IP.
Une attaque informatique touche le site de l'Etat du Valais depuis jeudi à la mi-journée. Celui-ci a été déconnecté par précaution. A ce stade, aucun dommage n'a été constaté.
"Les hackers ont disposé temporairement de droits étendus sur les sites internet et intranet de l'Etat du Valais, ce qui pourrait permettre de procéder à des modifications sur le site", précise Claude-Alain Berclaz, chef du Service cantonal de l'informatique. "Ceci n'a pour l'instant pas été constaté."
Cette attaque "est la première de cette ampleur", précise-t-il. L'acte malveillant n'a pas été revendiqué.
Opération de remise en état
Selon les autorités, ces attaques n'ont pas permis d’intrusion dans d’autres systèmes de l'Etat. Les activités opérationnelles internes ne sont pas touchées.
Le canton dit "avoir pris toutes les mesures pour sécuriser au maximum son environnement informatique" et appliquer "systématiquement les bonnes pratiques de cybersécurité". Il cherche à remettre ses systèmes en fonction "le plus rapidement possible".
Trend™ Research uncovered a campaign on TikTok that uses videos to lure victims into downloading information stealers, a tactic that can be automated using AI tools.
Threat actors are now using TikTok videos that are potentially generated using AI-powered tools to socially engineer users into executing PowerShell commands under the guise of guiding them to activate legitimate software or unlock premium features. This campaign highlights how attackers are ready to weaponize whichever social media platforms are currently popular to distribute malware.
This report details the observed tactics, techniques, and procedures (TTPs), indicators of compromise (IoCs), and the potential impact of this trend.
An unknown actor has been continuously creating malicious Chrome Browser extensions since approximately February, 2024. The actor creates websites that masquerade as legitimate services, productivity tools, ad and media creation or analysis assistants, VPN services, Crypto, banking and more to direct users to install corresponding malicious extensions on Google’s Chrome Web Store (CWS). The extensions typically have a dual functionality, in which they generally appear to function as intended, but also connect to malicious servers to send user data, receive commands, and execute arbitrary code.
This joint operation targeted the sophisticated ecosystem that allowed Europol’s European Cybercrime Centre has worked with Microsoft to disrupt Lumma Stealer (“Lumma”), the world’s most significant infostealer threat.
This joint operation targeted the sophisticated ecosystem that allowed criminals to exploit stolen information on a massive scale. Europol coordinated with law enforcement in Europe to ensure action was taken, leveraging intelligence provided by Microsoft.
Between 16 March and 16 May 2025, Microsoft identified over 394 000 Windows computers globally infected by the Lumma malware. In a coordinated follow-up operation this week, Microsoft’s Digital Crimes Unit (DCU), Europol, and international partners have disrupted Lumma’s technical infrastructure, cutting off communications between the malicious tool and victims. In addition, over 1 300 domains seized by or transferred to Microsoft, including 300 domains actioned by law enforcement with the support of Europol, will be redirected to Microsoft sinkholes.
The Head of Europol’s European Cybercrime Centre, Edvardas Šileris, said: “This operation is a clear example of how public-private partnerships are transforming the fight against cybercrime. By combining Europol’s coordination capabilities with Microsoft’s technical insights, a vast criminal infrastructure has been disrupted. Cybercriminals thrive on fragmentation – but together, we are stronger.”
La Digital Crimes Unit (DCU) de Microsoft, en collaboration avec des partenaires internationaux, s’attaque à l’un des principaux outils utilisés pour dérober massivement des données sensibles, qu’elles soient personnelles ou professionnelles, à des fines cybercriminelles. Le mardi 13 mai, la DCU de Microsoft a engagé une action en justice contre Lumma Stealer (« Lumma »), un malware spécialisé dans le vol d’informations, largement utilisé par des centaines d’acteurs de la menace cyber. Lumma vole des mots de passe, des cartes de crédit, des comptes bancaires et des portefeuilles de cryptomonnaies. Cet outil a permis à des criminels de bloquer des établissements scolaires afin de récupérer une rançon, de vider des comptes bancaires et de perturber des services essentiels.
Grâce à une décision de justice rendue par le tribunal fédéral du district nord de la Géorgie, la Digital Crimes Unit (DCU) de Microsoft a procédé à la saisie et à la mise hors ligne d’environ 2 300 domaines malveillants, qui constituaient l’infrastructure centrale de Lumma. Parallèlement, le département de la Justice américain (DOJ) a démantelé la structure de commande principale du malware et perturbé les places de marché où l’outil était vendu à d’autres cybercriminels. Europol, via son Centre européen de lutte contre la cybercriminalité (EC3), ainsi que le Centre de lutte contre la cybercriminalité du Japon (JC3), ont contribué à la suspension de l’infrastructure locale de Lumma.
Critical vulnerabilities in Versa Concerto that are still unpatched could allow remote attackers to bypass authentication and execute arbitrary code on affected systems.
Three security issues, two of them critical, were publicly disclosed by researchers at the vulnerability management firm ProjectDiscovery after reporting them to the vendor and receiving no confirmation of the bugs being addressed.
Versa Concerto is the centralized management and orchestration platform for Versa Networks' SD-WAN and SASE (Secure Access Service Edge) solutions.

Threat actors are advancing AI strategies and outpacing traditional security. CXOs must critically examine AI weaponization across the attack chain.
The integration of AI into adversarial operations is fundamentally reshaping the speed, scale and sophistication of attacks. As AI defense capabilities evolve, so do the AI strategies and tools leveraged by threat actors, creating a rapidly shifting threat landscape that outpaces traditional detection and response methods. This accelerating evolution necessitates a critical examination for CXOs into how threat actors will strategically weaponize AI across each phase of the attack chain.
One of the most alarming shifts we have seen, following the introduction of AI technologies, is the dramatic drop in mean time to exfiltrate (MTTE) data, following initial access. In 2021, the average MTTE stood at nine days. According to our Unit 42 2025 Global Incident Response Report, by 2024 MTTE dropped to two days. In one in five cases, the time from compromise to exfiltration was less than 1 hour.
In our testing, Unit 42 was able to simulate a ransomware attack (from initial compromise to data exfiltration) in just 25 minutes using AI at every stage of the attack chain. That’s a 100x increase in speed, powered entirely by AI.
Recent threat activity observed by Unit 42 has highlighted how adversaries are leveraging AI in attacks:
Discover how to intercept data stolen by cybercriminals via Telegram bots and learn to use it to clarify related threat landscape.
While analyzing malware samples uploaded to ANY.RUN’s Interactive Sandbox, one particular case marked as “phishing” and “Telegram” drew the attention of our security analysts.
Although this analysis session wasn’t attributed to any known malware family or threat actor group, the analysis revealed that Telegram bots were being used for data exfiltration. This led us to apply a message interception technique for Telegram bots, previously described on the ANY.RUN blog.
The investigation resulted in a clear and practical case study demonstrating how intercepting Telegram bot communications can aid in profiling the threat actor behind a relatively obscure phishing campaign.
Key outcomes of this analysis include:
Examination and technical analysis of a lesser known phishing campaign
Demonstration of Telegram API-based data interception techniques
Collection of threat intelligence (TI) indicators to help identify the actor
Recommendations for detecting this type of threat
KrebsOnSecurity last week was hit by a near record distributed denial-of-service (DDoS) attack that clocked in at more than 6.3 terabits of data per second (a terabit is one trillion bits of data). The brief attack appears to have been…
For reference, the 6.3 Tbps attack last week was ten times the size of the assault launched against this site in 2016 by the Mirai IoT botnet, which held KrebsOnSecurity offline for nearly four days. The 2016 assault was so large that Akamai – which was providing pro-bono DDoS protection for KrebsOnSecurity at the time — asked me to leave their service because the attack was causing problems for their paying customers.
Since the Mirai attack, KrebsOnSecurity.com has been behind the protection of Project Shield, a free DDoS defense service that Google provides to websites offering news, human rights, and election-related content. Google Security Engineer Damian Menscher told KrebsOnSecurity the May 12 attack was the largest Google has ever handled. In terms of sheer size, it is second only to a very similar attack that Cloudflare mitigated and wrote about in April.
After comparing notes with Cloudflare, Menscher said the botnet that launched both attacks bears the fingerprints of Aisuru, a digital siege machine that first surfaced less than a year ago. Menscher said the attack on KrebsOnSecurity lasted less than a minute, hurling large UDP data packets at random ports at a rate of approximately 585 million data packets per second.
“It was the type of attack normally designed to overwhelm network links,” Menscher said, referring to the throughput connections between and among various Internet service providers (ISPs). “For most companies, this size of attack would kill them.”
The cyberattackers claimed 2.1m pieces of customer data had been stolen from the Legal Aid Agency
Millions of pieces of personal data, including criminal records, have been stolen from legal aid applicants in a massive cyberattack.
The data, including national insurance numbers, employment status and financial data, was breached earlier this year, according to the Ministry of Justice (MoJ).
The cyberattackers claimed they had stolen 2.1 million pieces of data from people who had applied for legal aid since 2010 but the MoJ only said a “significant amount of personal data” had been breached.
An MoJ source put the breach down to the “neglect and mismanagement” of the previous government, saying vulnerabilities in the Legal Aid Agency (LAA) systems have been known for many years.
“This data breach was made possible by the long years of neglect and mismanagement of the justice system under the last government,” the source said.
Plusieurs comptes SwissPass ont été piratés depuis le début de l’année en Suisse romande. En Valais, la police recense 16 cas pour un préjudice total de 15’400 francs. Ce type de fraude s'étend au-delà du canton.
La police cantonale valaisanne a lancé une alerte après avoir enregistré une série de piratages de comptes SwissPass. Dans un communiqué publié le 20 mai, elle indique avoir reçu plusieurs signalements de connexions frauduleuses à ces comptes. Selon l’autorité, 16 cas ont été recensés depuis le début de l’année 2025 dans le canton, pour un préjudice total de 15’400 francs.
Les fraudeurs accèdent aux comptes grâce à des identifiants compromis, sans qu’un vol physique de la carte ne soit nécessaire. Une fois dans le compte, ils utilisent les moyens de paiement enregistrés comme Twint, la carte de crédit ou le paiement sur facture, pour acheter des billets de train, souvent à destination de la France, de l’Italie ou sur des liaisons transfrontalières. Cette méthode leur permet de détourner des montants importants sans jamais accéder au compte bancaire de la victime.
In April 2025, the Global Threat Hunting system of NSFOCUS Fuying Lab detected a significant increase in the activity of a new Botnet Trojan developed based on Go language. Given that many of its built-in DDoS attack methods are HTTP-based, Fuying Lab named it HTTPBot. The HTTPBot Botnet family first came into our monitoring scope in August 2024. Over the past few months, it has expanded aggressively, continuously leveraging infected devices to launch external attacks. Monitoring data indicates that its attack targets are primarily concentrated in the domestic gaming industry. Additionally, some technology companies and educational institutions have also been affected. The attack of this Botnet family is highly targeted, with attackers employing a periodical and multi-stage attack strategy to conduct continuous saturation attacks on selected targets.
In terms of technical implementation, the HTTPBot Botnet Trojan uses an “attack ID” to precisely initiate and terminate the attack process. It also incorporates a variety of innovative DDoS attack methods. By employing highly simulated HTTP Flood attacks and dynamic feature obfuscation techniques, it circumvents traditional rule-based detection mechanisms, including but not limited to the following detection bypass mechanisms:

The company behind the Signal clone used by at least one Trump administration official was breached earlier this month. The hacker says they got in thanks to a basic misconfiguration.
LONDON, May 14 (Reuters) - U.S. energy officials are reassessing the risk posed by Chinese-made devices that play a critical role in renewable energy infrastructure after unexplained communication equipment was found inside some of them, two people familiar with the matter said.
Power inverters, which are predominantly produced in China, are used throughout the world to connect solar panels and wind turbines to electricity grids. They are also found in batteries, heat pumps and electric vehicle chargers. While inverters are built to allow remote access for updates and maintenance, the utility companies that use them typically install firewalls to prevent direct communication back to China.
However, rogue communication devices not listed in product documents have been found in some Chinese solar power inverters by U.S experts who strip down equipment hooked up to grids to check for security issues, the two people said.
Over the past nine months, undocumented communication devices, including cellular radios, have also been found in some batteries from multiple Chinese suppliers, one of them said.
Reuters was unable to determine how many solar power inverters and batteries they have looked at. The rogue components provide additional, undocumented communication channels that could allow firewalls to be circumvented remotely, with potentially catastrophic consequences, the two people said.
Both declined to be named because they did not have permission to speak to the media.
"We know that China believes there is value in placing at least some elements of our core infrastructure at risk of destruction or disruption," said Mike Rogers, a former director of the U.S. National Security Agency. "I think that the Chinese are, in part, hoping that the widespread use of inverters limits the options that the West has to deal with the security issue."
A spokesperson for the Chinese embassy in Washington said: "We oppose the generalisation of the concept of national security, distorting and smearing China's infrastructure achievements."
Threat actor used malicious Google Invites and hidden Unicode “Private Use Access” characters (PUAs) to brilliantly obfuscate and hide a malicious NPM package.
On March 19th, 2025, we discovered a package called os-info-checker-es6 and were taken aback. We could tell it was not doing what it said on the tin. But what's the deal? We decided to investigate the matter and initially hit some dead ends. But patience pays off, and we eventually got most of the answers we sought. We also learned about Unicode PUAs (No, not pick-up artists). It was a roller coaster ride of emotions!
