Singapore Airlines (SIA) is the newest name on a growing list of carriers affected by the Amadeus cybersecurity incident, confirming that Amadeus IT Group, the global travel technology provider, accessed roughly 46,000 of its booking records through its systems.   The disclosure adds to a wave of airline cyberattacks that has now hit at least 15 carriers across Asia, Europe and Australia, and it highlights how cyberattacks on airlines reach passengers through shared third-party platforms rather than airlines' own networks. 

What Singapore Airlines Disclosed About the Amadeus Cybersecurity Incident 

SIA briefed the media on 3 November 2026. According to the airline, most of the affected records contained passengers' names, booking reference numbers, travel itineraries and booking classes.  A smaller group of about 620 records carried more sensitive details. For these, email addresses, phone numbers, travel document information and KrisFlyer membership numbers may also have been viewed.  The airline said no bank account or credit card data was exposed and no bookings were altered. SIA also stated that its own IT systems were not breached. It is reaching out directly to affected customers who have upcoming trips so they can change their booking reference numbers. 

Cathay Pacific: 53,000 Bookings Accessed Over Three Years 

Cathay Pacific went public with its own statement on 30 October 2026, updated at 16:11 HKT (GMT+8) that day. The Hong Kong carrier said Amadeus first notified it on 28 October 2026 and shared further details on 29 October.  According to Cathay, an unauthorized party had gained access to travel reservation data in Amadeus's systems "using login credentials assigned to its system account." Data supplied by Amadeus showed that around 53,000 Cathay Pacific bookings were affected, with the unauthorized access running from August 2023 to September 2026.  In most cases, the exposed information covers booking references, passenger names, and flight details. In a smaller subset, email and phone contacts, travel document details, and frequent flyer numbers may also have been accessed. Cathay said there is no evidence that financial or payment data was touched.  The airline said Amadeus has contained the incident, including through a password reset, and has added enhanced monitoring and detection on its systems. Amadeus has so far found no evidence that the data has been misused.  Cathay stressed that the incident "has not impacted and is not impacting" its own systems or operations. It has informed the relevant authorities that they are still analyzing the information from Amadeus and plans to notify affected customers individually once the details are confirmed. "We apologise to our customers for the concern and inconvenience caused by this incident," the airline said. 

Malaysia Airlines Urges Vigilance 

Malaysia Airlines issued its notice on 31 October 2026, describing Amadeus as its third-party airline reservation technology provider. The carrier said some customer information processed through Amadeus between August 2023, and September 2026 may have been affected.  The airline said its own IT systems were not compromised and that there is currently no evidence that financial information was accessed. It is working with Amadeus and other relevant parties to investigate and gauge the impact.  As a precaution, Malaysia Airlines asked customers to stay alert to suspicious or unsolicited messages, "particularly those requesting personal or financial information." The carrier said it would share further updates as more information emerges. 

Japanese and Korean Carriers Report Similar Airline Cyberattacks 

Japan Airlines (JAL) reported earlier that Amadeus had informed it of unauthorized access to reservation records for both JAL and Japan Transocean Air flights. About 92,000 customers were affected, making JAL the hardest-hit carrier so far. Names, booking references, and flight information were exposed.  Korean Air and Asiana Airlines also confirmed unauthorized access to data managed by Amadeus. Both said there was no evidence that their internal systems or databases had been breached. 

How Amadeus Explains the Breach 

Amadeus has attributed the exposure to a software glitch that made certain booking-display data accessible. That explanation sits alongside Cathay Pacific's account, which describes an unauthorized party using system account login credentials.  The company said its investigation is continuing and that it has found no evidence of payment or financial information was accessed. Amadeus also said there is no sign that the vulnerability was used for ransomware. It has since rolled out fixes, together with stronger monitoring and detection measures. 

The Full Reach of These Cyberattacks on Airlines 

At least 15 international airlines are either confirmed as directly affected or are investigating possible customer data exposure from the supply-chain attack on the Spanish IT and reservations company. Because the breach hit a centralized booking display environment, it reached flag carriers as well as the regional partners that route reservations through them. 

Major carriers with confirmed exposure 

Airline	Reported impact
Japan Airlines (JAL)	About 92,000 passenger records
Cathay Pacific Airways	About 53,000 passenger bookings
Singapore Airlines (SIA)	About 46,000 booking records
All Nippon Airways (ANA)	Up to 37,800 customer profiles
Malaysia Airlines	Customer data exposed across August 2023 to September 2026
Korean Air	Unauthorised access to customer reservation databases
Asiana Airlines	Passenger booking references exposed through system account credentials
Condor Airlines	Part of the German leisure carrier's international flight data accessed

 

Regional and subsidiary carriers 

Several smaller airlines were drawn in because they share back-end ticketing technology or corporate ties with the larger groups: 

Airline	Link to the breach
Japan Transocean Air (JTA)	Affected through parent company Japan Airlines
Air Do	Affected through shared system pathways with ANA
StarFlyer	Affected through shared system pathways with ANA
Solaseed Air	Affected through shared system pathways with ANA
Ibex Airlines	Still determining the scope of exposure via its ANA integration
Oriental Air Bridge	Still determining the scope of exposure via its ANA integration

Under investigation 

Qantas Airways is formally investigating whether any Australian customer files were compromised. The airline maintains that its internal databases have not been breached. 

What the Amadeus Cybersecurity Incident Means for Travelers? 

With the access window stretching from August 2023 to September 2026, the Amadeus cybersecurity incident spans more than three years and stands out among airline cyberattacks for how many carriers it touched through a single provider. None of the affected carriers has reported misuse of the data so far, and no airline has said payment details were taken.   Even so, names, itineraries and booking references can be enough for convincing phishing attempts. That is why carriers such as Malaysia Airlines and SIA are asking passengers to watch for suspicious messages and, where advised, change their booking references.   As investigations continue, more airlines may update their figures on how far these cyberattacks on airlines have reached. 

As per Boston Scientific’s Aug. 30 update, “the unauthorized activity is limited to certain on-premises systems,” providing the clearest indication yet of the scope of the cybersecurity incident that has disrupted the medical device maker’s global network and business operations. Boston Scientific said the investigation into the disruption remains ongoing, with third-party cybersecurity experts. Based on its investigation to date, the company said it has found no indication of unauthorized activity in its environment related to the incident since Aug. 25. The company also clarified that its cloud-based systems and applications have not been affected. The unauthorized activity identified so far is confined to only limited on-premises systems. The clarification comes as Boston Scientific continues working to restore systems supporting manufacturing, ordering and shipping. The company has not established a timeline for a full return to normal operations.

Boston Scientific Ordering and Shipping Recovery Underway 

Boston Scientific said its confidence in restoring ordering, shipping and related system access “continues to increase” and that it is working toward a partial restoration of shipping for some products during the week following its Aug. 30 update. The company said it expects ordering and shipping to ramp up to full capacity once it can demonstrate that the restored operations are fully functional. For now, customers can continue to submit orders electronically through Electronic Data Interchange (EDI) and local applications. Those orders can be placed into a queue for future fulfillment, including orders submitted through the Global Health Exchange (GHX). The latest update indicates that the company’s ability to receive orders electronically has remained intact even while systems required to fulfill and ship those orders have been disrupted. Boston Scientific has not provided a specific date for when full ordering and shipping capacity will return.

Investigation Has Not Confirmed a Data Breach 

Boston Scientific has not said that the cybersecurity incident resulted in a confirmed data breach. Its investigation remains focused on determining the nature, scope, and impact of the unauthorized activity. The Aug. 30 update also provides a more specific picture of the affected technology environment. While certain on-premises systems have been impacted, Boston Scientific said there has been no impact to its cloud-based systems and applications. The company previously said it had found no indication of unauthorized activity in its environment related to the incident since Aug. 25. It has not disclosed whether data was exfiltrated or whether ransomware was involved.

Impact on Medical Devices Remains Limited Based on Current Information

Boston Scientific previously said the incident had not affected devices that are not connected to a Boston Scientific network or clinicians’ ability to use those devices. For Cardiac Rhythm Management (CRM) products, the company reported no known impact on implantable device function, remote monitoring for devices that were already being remotely monitored before the disruption, or programmer interrogations. However, new remote-monitoring activations have been affected. For new CRM implants other than insertable cardiac monitors (ICMs), remote-monitoring communicators cannot currently be activated. As a result, available device data cannot reach remote patient-management systems until activation is possible. Newly implanted ICMs must be activated through the Boston Scientific Clinic Assistant app, but new ICMs cannot currently pair with patients’ remote-monitoring mobile phones. Recorded episodes can still be transmitted through an in-person interrogation using the app’s “Interrogate” function. Boston Scientific said that once its systems are restored and home-monitoring equipment is paired, recorded data will be transmitted to the remote-monitoring system. The company has also said there is no evidence that the affected network environment has increased cybersecurity risks for hospital networks through Boston Scientific devices.

Boston Scientific Continues Incident Response

Boston Scientific said it continues to work with CrowdStrike and other external cybersecurity specialists as the investigation and recovery effort proceeds. The company has been prioritizing systems with the greatest impact on customers and product delivery while working to recover its core business systems. Customers can continue communicating with sales representatives and other Boston Scientific employees through normal channels, including email, established digital platforms and existing connections. The company has acknowledged the potential challenges for customers, patients and suppliers as the disruption continues and thanked them for their patience and partnership. Boston Scientific disclosed the incident in an 8-K filing with the U.S. Securities and Exchange Commission on Aug. 26. The company said it will provide additional updates as appropriate. For now, the latest disclosure narrows the known technical scope of the incident: Boston Scientific says the unauthorized activity is limited to certain on-premises systems, while cloud-based systems and applications remain unaffected. At the same time, the continued disruption to manufacturing, order fulfillment, and shipping means the operational consequences of the attack remain significant as the investigation and recovery effort continue.

Oz Hair and Beauty has confirmed that customers’ personal information was accessed after an unauthorized third party briefly gained access to its online purchase and order platform. The company said the incident affected information connected to purchases made before August 2026. The potentially accessed data included customers’ full names, email addresses and/or mobile phone numbers, as well as purchase-history information such as transaction currency, total spending and broad location details, including city, state, country and postcode.

Oz Hair and Beauty Data Breach Involved Customer Information 

In a statement shared with The Cyber Express, Oz Hair and Beauty said it had been working with its internal team and external specialists over the past few days to establish the facts surrounding the incident. “We became aware of this and have been working with our internal team and external specialists to confirm all the facts over the last few days,” the company said. Oz Hair and Beauty confirmed that its website does not store credit card information. “The website does not store credit card information, so your payment details are completely safe,” the company said. The company also confirmed that banking details and home addresses had not been leaked. The company has not confirmed how many customers were affected.

Investigation Underway

Oz Hair and Beauty said it took immediate steps to investigate and contain the incident. The company commenced a forensic investigation with support from senior technical specialists from its cloud e-commerce platform provider. It is also reviewing and enhancing its cybersecurity posture and data retention policies to reduce the risk of similar incidents. The company said affected customers had been notified and that it was taking appropriate steps to support them. Oz Hair and Beauty is also preparing a full communication about the incident, which is currently being handled by its dedicated cyber team. “We want to make sure the right information goes out on something this important,” the company said.

Delay in Customer Notifications

Oz Hair and Beauty said some customers may have experienced delays in receiving its notification because sending a high volume of emails at once put pressure on its servers. The company apologized for the delay and asked customers who contact it directly to allow up to 48 hours for a response.

Customers Warned About Suspicious Communications

Oz Hair and Beauty has advised customers to remain alert for unusual phone calls or emails requesting personal information, payments or proof of identity. The company specifically warned customers to be cautious of: “any unusual communications by phone or email requesting information, payments or proof of identity.” Customers should avoid providing sensitive information in response to unsolicited requests and independently verify suspicious communications. The company has also advised customers who receive spam emails to use the relevant spam-reporting features provided by their email services.

Customers Can Continue Placing Orders

Oz Hair and Beauty has said customers can continue placing orders with the company. “You are safe to continue placing orders with us,” the company said. “We know this is unsettling and we appreciate you bearing with us while we work through it properly,” the company added.

Levi Strauss cyberattack has exposed certain corporate information after an unauthorized third party gained access to company files through compromised employee computers, according to a filing with the U.S. Securities and Exchange Commission. Levi Strauss & Co. said it recently detected a cybersecurity incident involving unauthorized access to three company-issued computers. The company said the access was enabled through social engineering techniques, allowing the attackers to reach company files. According to the filing, the company initiated its response protocols after detecting the incident and implemented containment measures. It also launched an investigation that remains ongoing and engaged third-party cybersecurity experts to assist with the response.

Levi Strauss Cyberattack Investigation Remains Ongoing

Based on preliminary findings, Levi Strauss said it believes certain corporate information was accessed and exfiltrated during the incident. However, the company said its rapid response efforts successfully contained and terminated the unauthorized access. The company also stated that no consumer data had been impacted as of the date of the filing. Levi Strauss said the incident has not interrupted its business operations and that, based on the information currently available, it does not believe the incident has had or is reasonably likely to have a material impact on its business strategy, operations, financial condition, or results of operations. The company said it has provided and will provide notifications to affected parties and applicable regulators as appropriate and in accordance with applicable law. Levi Strauss & Co., headquartered in San Francisco, is known for its Levi's denim brand. The company reported net revenues of $6.3 billion for 2025, up 4% compared with fiscal year 2024 and 7% on an organic basis. The company designs and markets jeans, casual wear and related accessories for men, women and children under the Levi's, Levi Strauss Signature, and Beyond Yoga brands. Its products are sold in approximately 120 countries through chain retailers, department stores, online sites, and approximately 3,300 retail stores and shop-in-shops.

Retail Cybersecurity Incidents Continue

The Levi Strauss cyberattack comes as several major retailers have reported cybersecurity incidents involving their own systems or third-party service providers. In the first week of August 2026, the De Bijenkorf cyberattack affected the Dutch luxury department store chain after an incident involving one of its external logistics partners. The disruption affected order processing, deliveries, returns, and refunds, while the company said there was no evidence that its own infrastructure had been compromised. In October 2025, Spanish fashion retailer Mango confirmed a Mango data breach after an external marketing service provider experienced unauthorized access to limited customer information. Mango said its corporate systems were not compromised and that financial or login details remained secure. The exposed information included customers’ first names, countries, postal codes, email addresses, and phone numbers. The company said last names, banking information, credit card details, and passwords were not affected. Retailers also faced law enforcement action following a series of attacks. In July 2025, the UK’s National Crime Agency arrested four people suspected of orchestrating cyberattacks against Marks & Spencer, Co-op, and Harrods. The suspects were detained in the West Midlands and London and faced charges under the Computer Misuse Act, blackmail, money laundering, and involvement in an organized crime group. Meanwhile, in May 2025, Victoria’s Secret took down its U.S. website and some in-store services following what it described as a Victoria’s Secret security incident. The company said the precautionary shutdown was intended to address the incident while its team worked to restore operations. Its Victoria’s Secret and PINK stores remained open. The latest incident involving Levi Strauss adds another case to a growing series of cybersecurity incidents affecting major retailers, with the company continuing its investigation into the access and information involved.
