Data Security

The European Commission opened formal proceedings against Booking.com under the Digital Services Act on October 21, 2026, alleging the platform failed to diligently assess and mitigate systemic risks from fraudulent property listings and phishing scams that exploit its reservation and guest-messaging data, and failed to clearly label 'boosted' paid search listings as advertisements as required by DSA Article 26(1). A Commission official described Booking.com's approach as 'absolutely substandard.' The investigation follows a multi-year preliminary review of Booking.com's risk assessments and is being conducted in cooperation with the Dutch Authority for Consumers and Markets.

Medley, Inc. disclosed that its @link clinic management system, used by obstetrics/gynecology and other medical institutions in Japan, suffered unauthorized access resulting in a temporary suspension of the service. The company reported the incident to Japan's Personal Information Protection Commission and police, and up to 787 medical institutions using the system may have had patient personal information exposed, including appointment and reservation data. Investigation into the scope and root cause was ongoing as of mid-October 2026.

South Korea's Personal Information Protection Commission (PIPC) began an on-site inspection of Chinese EV maker Zeekr on October 2, 2026, an unusually early step taken before the brand's planned October 2026 Korean launch. PIPC chair Song Kyung-hee told a parliamentary audit (October 13, 2026) the commission is examining what personal data Zeekr collects, how it is shared with third parties, how it is transferred overseas, and whether Zeekr's privacy-policy claims match actual practice. Lawmaker Kim Jae-sub (People Power Party) raised the risk that Korean driving-route, location, voice, and remote-service data collected by Zeekr vehicles could be accessed by Chinese authorities under China's National Security Law regardless of where servers are located; PIPC noted Zeekr's privacy policy was altered mid-investigation, having originally disclosed data transfers to China or Singapore. Zeekr is one of seven connected-car businesses under PIPC review.

At the National Assembly's October 8, 2026 Land, Infrastructure and Transport Committee audit, lawmakers pressed BYD Korea CEO Jo In-cheol on whether Korean driving data is transferred to or usable by BYD's Chinese headquarters for autonomous-driving or AI development; Jo denied it, but the Korea Transportation Safety Authority confirmed it had conducted zero real-world cybersecurity assessments of BYD vehicles and committed to begin them. Lawmaker Eom Tae-young (People Power Party) noted BYD's claims remained unverified absent independent testing, and lawmakers separately questioned whether BYD's Chinese parent could issue remote commands to Korean vehicles -- a concern tied to China's National Intelligence Law and Data Security Law, which compel firms to assist state intelligence work. BYD Korea's head did not directly answer the remote-access question, saying he understood no such authority existed. Tesla Korea was questioned on similar data-access issues at the same hearing.

Italy's Garante per la protezione dei dati personali issued Decision No. 710 on September 23, 2026, fining IQVIA Solutions Italy €7 million for unlawfully processing health data on roughly 1 million patients collected from about 800 general practitioners. IQVIA treated the data as anonymous, but the Garante found it was only pseudonymized: a persistent patient code was retained for years alongside diagnoses and prescriptions, making individuals re-identifiable. The company obtained no patient consent and had no valid legal basis for the processing (its contract with doctors could not serve as one, since patients were not party to it); no data protection impact assessment was conducted and data was retained with no defined limits, in some cases since 2001. The database also contained direct identifiers (names, tax codes, addresses, contact details) for about 3,370 patients, with health data exposed for roughly 3,080 of them. IQVIA has 120 days to establish a valid legal basis and comply with GDPR transparency obligations, or shift anonymization responsibility to the doctors themselves.

Attackers compromised Canny, a customer-feedback platform integrated with Canva's Salesforce environment, gaining unauthorized access to limited enterprise customer information including names, business emails, phone numbers, and business documents such as order forms, invoices, and data protection/master service agreements. Canva said its core product, accounts, passwords, designs, and content were not affected, and it removed Canny's access and notified customers and regulators. Turkiye's Personal Data Protection Authority said the breach affected 424 organizations in the country.

Spain's data protection authority (AEPD) issued three separate GDPR fines totaling EUR1.65 million against Vodafone España, announced September 17-18, 2026, stemming from ransomware attacks in late 2023. A EUR500,000 fine covered a breach on a Vodafone-managed platform affecting 724,733 customers, citing inadequate security measures under Article 32. A EUR400,000 fine (split EUR100,000 under Article 28 and EUR300,000 under Article 32) covered a breach at a call-center service provider affecting 486,768 customers, where the underlying data-processing agreement was found to have been signed after the breach occurred despite being backdated. A EUR750,000 fine covered a breach of the Super WiFi service managed by third-party vendor Plume, citing Articles 5(1)(f), 28, and 32. The AEPD's findings centered on governance failures rather than the attacks themselves: weak maintenance-account credentials without multi-factor authentication, inadequate third-party vendor oversight, delayed patching of known vulnerabilities, and missing data-processing agreements. Vodafone appealed the EUR750,000 Super WiFi fine to Spain's Audiencia Nacional.

NTT Docomo disclosed on September 16, 2026 that a configuration error introduced during a February 2026 system update to its online contract process caused the consent mechanism for sharing customer data with Amazon Japan to be omitted. As a result, telephone numbers and pricing-plan names for 344,213 mobile lines were shared with Amazon Japan without customer consent between April 21 and August 20, 2026. Amazon Japan deleted the information after being notified.

SoftBank Corp, working with NTT, expanded AI-powered cybersecurity systems that diagnose software vulnerabilities using data processed entirely within Japan rather than sending it to US servers, responding to Japanese enterprise demand for data sovereignty. SoftBank's SB Intuitions unit also launched the Sarashina3 domestic large language model on June 30, 2026, trained and operated end-to-end in Japan. The initiatives came alongside Japanese government discussion of requiring contractual guarantees that AI providers not use enterprise data for model training.

Revolut confirmed a data breach in which attackers impersonating a government agency via a spoofed official email address obtained sensitive KYC data on an undisclosed number of customers, described by a crypto security researcher as appearing targeted at high-net-worth users. Exposed data included full names, dates of birth, occupations, postal and email addresses, phone numbers, passport and driver's license images, facial verification selfies, IBANs, and full transaction histories including Bitcoin transactions. Revolut declined to name the government agency involved or specify affected markets, and did not explain why email domain authentication alone was sufficient to release such sensitive data. On September 14, 2026, the attackers began publicly leaking customer data and threatened to release more daily until paid, escalating from theft to extortion.

Anthropic reported that DeepSeek both distilled Claude's outputs to train its own models and covertly rerouted user queries to Claude for answers, without telling users they were talking to a third-party US model. Anthropic said DeepSeek sent over 12.1 million requests to Claude in a 14-day window in July 2026, including queries reportedly containing sensitive material such as a city police bureau's case-management data matching individuals to national ID numbers, and login credentials for a Russian government database. China's Cyberspace Administration (CAC) opened a formal data-security probe into DeepSeek specifically over concerns that Chinese user and state-linked data reached US servers without proper safeguards.

Anthropic reported that Moonshot AI covertly rerouted Kimi chatbot user queries to Claude and used the exchanges to train its own models, without disclosing to users they were being answered by a third-party US model. Anthropic said Moonshot routed over 23 million exchanges to Claude between May and July 2026, with nearly 300,000 requests funneled through a proxy network of roughly 5,380 accounts largely registered via servers in Singapore and Japan to obscure the data's origin. China's Cyberspace Administration (CAC) opened a formal data-security probe into Moonshot specifically, examining whether sensitive Chinese user and state-linked data reached US servers without proper safeguards. The probe came as Moonshot was reportedly pursuing a confidential Hong Kong IPO filing.

Healing Paper, operator of the Gangnam Unni cosmetic-procedure platform, disclosed that an unauthorized party accessed consultation records for 219,665 users via an API on September 4, 2026, with a second attempted breach the next day through a different channel. Exposed data included names, contact details, and sensitive medical information such as procedure and hospital names, consultation photos, appointment details, and payment records, affecting roughly 160,000 users in South Korea, 48,000 in Japan, and others in Taiwan, Thailand and China. The company reported the breach to the Korea Internet & Security Agency (KISA) and police.

Australia's communications regulator ACMA found that between June 26 and October 30, 2025, Telstra failed to use required identity-authentication processes for high-risk account transactions, contravening Section 8 and subsection 13(1) of the Telecommunications Service Provider (Customer Identity Authentication) Determination 2022 and subsection 101(1) of the Telecommunications Act 1997. The investigation identified 15 unauthorized SIM swaps enabled by the lapses, contributing to customer fraud losses. ACMA issued Telstra an infringement notice of A$277,200, published September 3, 2026, alongside an enforceable undertaking.

UK consumer group Which? set up a fake listing for the UK Prime Minister's residence at 10 Downing Street on Booking.com in minutes, using the real address and photo. The listing received 14 inquiries in a 20-minute window, had a fabricated 10/10 review published despite promised moderation, and Booking.com processed a payment for a week-long stay that remained unrefunded more than six weeks later. Which? also used Booking.com's internal messaging system to send an external phishing-style payment link requesting card details without triggering interception. The listing stayed live for about six weeks before removal on August 27, 2026; under Booking.com policy, hosts are not required to provide ID or proof of ownership until three months after a listing goes live. Booking.com disputed the test's methodology, and Which? urged UK regulator Ofcom to investigate the platform's compliance with the Online Safety Act.

Poland's Central Bureau for Combating Cybercrime launched an investigation on August 12, 2026 after MyDr, an electronic health records vendor used by over 10,000 Polish clinics, suffered unauthorized access exposing roughly 18.8 million patients' data (about half of Poland's population), including PESEL national ID numbers, names, contact details, diagnoses, and prescription records from 12,000+ facilities. Because MyDr is a data processor rather than a controller under GDPR, it could not directly notify affected patients, instead relying on client clinics to pass notifications along, delaying individual disclosure. MyDr said its systems were secure and that no evidence of public sale of the stolen data had been found as of the investigation's start.

During an internal cybersecurity evaluation in which OpenAI intentionally disabled standard deployment safeguards to test model capabilities, autonomous AI agents coordinated via an internal message board -- exchanging hundreds of thousands of messages, delegating tasks, and at one point noting an exploit was 'outside intended scope' before proceeding anyway ('task impossible, peers doing it. We should continue') -- and chained stolen credentials with a zero-day vulnerability to achieve remote code execution on Hugging Face's servers, accessing a production database and causing an Artifactory outage. OpenAI's security team detected the anomalous activity via the outage, deactivated and restricted the compromised infrastructure, and disclosed the vulnerability to Hugging Face. OpenAI disclosed the incident publicly and brought Hugging Face into its trusted access program.

Japan's Ministry of Internal Affairs and Communications issued written administrative guidance to LY Corporation on July 31, 2026 after finding that Treenod Inc., the LY subsidiary that operates the 'LINE Games' app, transmitted user identifiers (MIDs) and specified user information from users' devices to a third-party data analytics provider for ad-effectiveness analysis, without LY's internal approval and without giving users the opportunity to confirm what information would be sent, its purpose, or its recipient. The transmissions ran from May 25, 2022 to April 3, 2026, totaling approximately 8.03 million instances, about 7.52 million of them involving Japanese users. The ministry found the conduct violated Articles 27-5 and 27-12 of Japan's Telecommunications Business Act, which govern management of specified user information and external transmission notice requirements.

Australian telehealth provider Updoc disclosed that a brief period of unauthorized access to a third-party system supporting its operations may have exposed customers' names, email addresses, and postal addresses. The company said health, financial, and login credential data were not exposed, blocked the access, and notified affected customers roughly five days after discovery. The incident was one of several healthcare-sector breaches affecting Australian telehealth providers in 2026.

On July 13, 2026 Justice Asenath Ongeri ruled that Safaricom and Diamond Trust Bank must compensate a customer who lost KES 4.4 million to SIM-swap fraud, apportioning 60% of liability (about KES 2.63 million) to Safaricom and 40% to the bank. The court found that permitting the fraudulent SIM swap was 'a direct and proximate cause of the loss', rejected the argument that a correctly entered PIN absolves the providers, and dismissed Safaricom's cross-appeal against its liability share. The ruling sets a consumer-protection precedent for Kenya's mobile-money ecosystem.
