Hackers leak data of 88 million AT&T customers with decrypted SSNs; latest breach raises questions about links to earlier Snowflake-related attack.
Hackers have leaked what they claim is AT&T’s database which was reportedly stolen by the ShinyHunters group in April 2024 after they exploited major security flaws in the Snowflake cloud data platform. But is this really the Snowflake-linked data? We took a closer look.
As seen by the Hackread.com research team, the data was first posted on a well-known Russian cybercrime forum on May 15, 2025. It was re-uploaded on the same forum on June 3, 2025, after which it began circulating among other hackers and forums.
After analyzing the leaked data, we found it contains a detailed set of personal information. Each of these data points poses a serious privacy risk on its own, but together, they create full identity profiles that could be exploited for fraud or identity theft. The data includes:
Full names
Date of birth
Phone numbers
Email addresses
Physical addresses
44 Million Social Security Numbers (SSN) (43,989,219 in total)
Le Département fédéral de la Défense a ouvert une enquête administrative sur une présumée transmission d'informations sensibles du Service de renseignement de la Confédération (SRC) à la Russie entre 2015 et 2020, notamment via l'entreprise russe de cybersécurité Kaspersky. Cette affaire de fuites de données sensibles apparaît dans un rapport interne du SRC que SRF Investigativ a pu consulter.
En novembre 2020, des services secrets alliés mettent en garde le service de renseignement suisse de potentielles fuites d'informations sensibles aux services secrets russes. Après enquête, le SRC reconnaît ces allégations de "partage illégal de données" dans un rapport secret datant de 2021, que SRF Investigativ a pu consulter. Selon ce rapport, un agent des services de renseignement suisses aurait effectivement transmis des informations hautement sensibles à Kaspersky, une société russe de cybersécurité.
L'information aurait ensuite été divulguée aux services de renseignement russes via Kaspersky, d'après une deuxième agence de renseignement alliée, faisant courir "un risque de mise en danger de vies humaines". Les deux services de renseignement "amis", essentiels pour le travail du SRC et la sécurité de la Suisse, ont menacé de "cesser toute coopération avec le SRC" si l'employé mis en cause à la tête du service cyber du SRC continuait à y travailler.
Kaspersky, le premier des "contacts réguliers" de l'équipe cyber du SRC
Kaspersky a déjà été accusé à plusieurs reprises de collaborer avec le Kremlin et ses services secrets. L'entreprise, avec laquelle le SRC a collaboré, est donc évitée depuis des années par les services gouvernementaux de nombreux pays occidentaux.
Mais pour l'équipe cyber du SRC, l'entreprise Kaspersky arrive en tête d'un rapport classé sous la rubrique "Contacts réguliers". La société de cybersécurité serait "essentielle" pour le travail de l'équipe cyber, avait d'ailleurs déclaré l'ancien chef de cette équipe mis en cause par les services de renseignement alliés. Selon lui, "le SRC ne dispose pas de l'expertise et des ressources suffisantes pour détecter de manière indépendante et préventive les activités de pira
The compliance company said the customer data exposure was caused by a product change.
ompliance company Vanta has confirmed that a bug exposed the private data of some of its customers to other Vanta customers. The company told TechCrunch that the data exposure was a result of a product code change and not caused by an intrusion.
Vanta, which helps corporate customers automate their security and compliance processes, said it identified an issue on May 26 and that remediation will complete June 4.
The incident resulted in “a subset of data from fewer than 20% of our third-party integrations being exposed to other Vanta customers,” according to the statement attributed to Vanta’s chief product officer Jeremy Epling.
Epling said fewer than 4% of Vanta customers were affected, and have all been notified. Vanta has more than 10,000 customers, according to its website, suggesting the data exposure likely affects hundreds of Vanta customers.
One customer affected by the incident told TechCrunch that Vanta had notified them of the data exposure. The customer said Vanta told them that “employee account data was erroneously pulled into your Vanta instance, as well as out of your Vanta instance into other customers’ instances.”
Detailed blueprints of Russia’s modernized nuclear weapon sites, including missile silos, were found leaking in public procurement database.
Russia is modernizing its nuclear weapon sites, including underground missile silos and support infrastructure. Data, including building plans, diagrams, equipment, and other schematics, is accessible to anyone in the public procurement database.
Journalists from Danwatch and Der Spiegel scraped and analyzed over two million documents from the public procurement database, which exposed Russian nuclear facilities, including their layout, in great detail. The investigation unveils that European companies participate in modernizing them.
According to the exclusive Der Spiegel report, Russian procurement documents expose some of the world’s most secret construction sites.
“It even contains floor plans and infrastructure details for nuclear weapons silos,” the report reads.
German building materials and construction system giant Knauf and numerous other European companies were found to be indirectly supplying the modernization through small local companies and subsidiaries.
Knauf condemned the Russian invasion of Ukraine and announced its intention to withdraw from its Russian business in 2024. Knauf told Der Spiegel that it only trades with independent dealers and cannot control who ultimately uses its materials in Russia.
Danwatch jointly reports that “hundreds of detailed blueprints” of Russian nuclear facilities, exposed in procurement databases, make them vulnerable to attacks.
“An enormous Russian security breach has exposed the innermost parts of Russia’s nuclear modernization,” the article reads.
“It’s completely unprecedented.”
The journalists used proxy servers in Russia, Kazakhstan, and Belarus to circumvent network restrictions and access the documents. The rich multimedia in the report details the inner structure of bunkers and missile silos.
Adidas on Tuesday officially confirms a third-party breach has led to the compromise of customer data, but questions remain as to whose customer data was impacted and where.
The German sportswear company was reported by Cybernews to have sent breach notifications to its regional customers in Turkey and Korea earlier this month.
But now, it appears Adidas has posted an official notice on both its German and English-language websites about what could be one singular cyber incident impacting its entire network – or possibly a third breach impacting another Adidas regional network.
Titled “Data Security Information,” Adidas stated it recently became aware “that an unauthorized external party obtained certain consumer data through a third-party customer service provider.”
Adidas confirms customer data was stolen in a recent third-party vendor breach on its website, adidas-group.com. Image by Cybernews.
Cybernews, which happened to cover both the Adidas Turkey and the Adidas Korea breaches as they hit the news cycle in their respective countries, has reached out to Adidas for the second time this month, looking for further clarification.
So far, there has been no response to either inquiry at the time of this report, but Cybernews will update our readers if that changes.
The Korean breach notice states the attackers were able to obtain information customers submitted to the Adidas customer center in 2024 and previous years.
Reportedly, the leaked information includes names, email addresses, phone numbers, dates of birth, and other personal details, as was similarly reported in the Turkish media.
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.
U.K. retail giant Marks & Spencer has confirmed hackers stole its customers’ personal information during a cyberattack last month.
In a brief statement with London’s stock exchange on Tuesday, the retailer said an unspecified amount of customer information was taken in the data breach. The BBC, which first reported the company’s filing, cited a Marks & Spencer online letter as saying that the stolen data includes customer names, dates of birth, home and email addresses, phone numbers, household information and online order histories.
The company also said it was resetting the online account passwords of its customers.
Marks & Spencer continues to experience disruption and outages across its stores, with some grocery shelves remaining empty after the hack affected the company’s operations. The company’s online ordering system for customers also remains offline.
It’s not clear how many individuals’ data was stolen during the hack. When reached by TechCrunch, Marks & Spencer spokesperson Alicia Sanctuary would not say how many individuals are affected and referred TechCrunch to its online statement. Marks & Spencer had 9.4 million online customers as of 30 March 2024, per its most recent annual report.
TeleMessage, a company that makes a modified version of Signal that archives messages for government agencies, was hacked.
A hacker has breached and stolen customer data from TeleMessage, an obscure Israeli company that sells modified versions of Signal and other messaging apps to the U.S. government to archive messages, 404 Media has learned. The data stolen by the hacker contains the contents of some direct messages and group chats sent using its Signal clone, as well as modified versions of WhatsApp, Telegram, and WeChat. TeleMessage was recently the center of a wave of media coverage after Mike Waltz accidentally revealed he used the tool in a cabinet meeting with President Trump.
The hack shows that an app gathering messages of the highest ranking officials in the government—Waltz’s chats on the app include recipients that appear to be Marco Rubio, Tulsi Gabbard, and JD Vance—contained serious vulnerabilities that allowed a hacker to trivially access the archived chats of some people who used the same tool. The hacker has not obtained the messages of cabinet members, Waltz, and people he spoke to, but the hack shows that the archived chat logs are not end-to-end encrypted between the modified version of the messaging app and the ultimate archive destination controlled by the TeleMessage customer.
Verisource Services, an employee benefits administration service provider, has determined that a previously announced data breach was far worse than initially thought and has affected up to 4 million individuals. The Houston, Texas-based company detected a hacking incident on February 28, 2024, that disrupted access to some of its systems. Third-party cybersecurity and incident response experts were engaged to investigate the incident and determine the nature and scope of the unauthorized activity.
The forensic investigation confirmed hackers had access to its network and exfiltrated files on February 27, 2024. At the time of the initial announcement, Verisource Services said names, dates of birth, genders, and Social Security numbers had been stolen. The affected individuals included employees and dependents of clients who used its services, which include HR outsourcing, benefits enrollment, billing, and administrative services.
The data breach was initially reported as affecting 1,382 individuals, but as the investigation progressed, it became clear that the breach was worse than initially thought. In August 2024, the data breach was reported to the HHS’ Office for Civil Rights (OCR) as involving the protected health information of 112,726 individuals. The most recent notification to the Maine Attorney General indicates up to 4 million individuals have been affected, a sizeable increase from previous estimates. The OCR breach portal still lists the incident as affecting 112,726 patients and plan members of its HIPAA-regulated entity clients, although that total may well be updated in the coming days.
Verisource Services explained in the breach notice that the data review was not completed until April 17, 2025, almost 14 months after the security incident was detected. Verisource Services reported the security incident to the Federal Bureau of Investigation, and several additional security measures have been implemented to improve its security posture. Notification letters had previously been sent to some affected individuals; however, the bulk of the notification letters have only recently been mailed. Verisource Services said complimentary credit monitoring and identity theft protection services have been offered to the affected individuals, who will also be protected with a $1,000,000 identity theft insurance policy.
SK Telecom, South Korea’s largest telecom company, disclosed a data leak involving a malware infection.
SK Telecom is South Korea’s largest wireless carrier — it has tens of millions of subscribers and holds roughly half of the local market.
The company revealed on Tuesday in a Korean-language statement posted on its website that it detected an intrusion on April 19. An investigation showed that the attackers deployed malware and managed to obtain personal information belonging to customers.
Following the incident, SK Telecom is offering customers a free SIM protection service designed to prevent SIM swapping, which suggests that the leaked data could be leveraged for such activities.
MTN Group said an “unknown third-party has claimed to have accessed data linked” to parts of its system and that the incident “resulted in unauthorised access to personal information of some MTN customers in certain markets.”
A surveillance tool meant to keep tabs on employees is leaking millions of real-time screenshots onto the open web.
Your boss watching your screen isn't the end of the story. Everyone else might be watching, too. Researchers at Cybernews have uncovered a major privacy breach involving WorkComposer, a workplace surveillance app used by over 200,000 people across countless companies.
The app, designed to track productivity by logging activity and snapping regular screenshots of employees’ screens, left over 21 million images exposed in an unsecured Amazon S3 bucket, broadcasting how workers go about their day frame by frame.
