UnitedHealth has recently confirmed the extent of the damage caused by the massive Change Healthcare ransomware attack. The company revealed that a significant amount of medical and patient data was stolen, with breach notifications set to go out in July.

Last week, UnitedHealth published a data breach notification, stating that a “substantial quantity of data” for a “substantial proportion of people in America” had been exposed. The exact number of affected individuals remains unknown, but UnitedHealth CEO Andrew Witty mentioned during a congressional hearing that “maybe a third” of all Americans’ health data might have been exposed.

The stolen data includes a wide range of sensitive information, such as:

  • Health insurance information (e.g., primary, secondary or other health plans/policies, insurance companies, member/group ID numbers, and Medicaid-Medicare-government payor ID numbers);
  • Health information (e.g., medical record numbers, providers, diagnoses, medicines, test results, images, care and treatment);
  • Billing, claims, and payment information (e.g., claim numbers, account numbers, billing codes, payment cards, financial and banking information, payments made, and balance due); and/or
  • Other personal information such as Social Security numbers, driver’s licenses or state ID numbers, or passport numbers.

Change Healthcare has stated that the scope of exposed data may vary for each individual and that patients’ complete medical histories have not been seen in the stolen data.

In a Change Healthcare data breach notification, the company explains the steps they are taking to address the issue and offers resources for those who believe their personal data may have been impacted. They also mention that they are providing two years of complimentary credit monitoring and identity theft protection services for affected individuals.

Change Healthcare plans to mail formal data breach notification letters starting in late July. However, they might not have mailing addresses for all impacted individuals. In the meantime, those affected can visit changecybersupport.com for more information and instructions on how to sign up for free credit monitoring and learn about potential risks associated with the stolen data.

The Change Healthcare ransomware attack

The data breach notifications are a result of a February ransomware attack on UnitedHealth subsidiary Change Healthcare, during which attackers stole 6 TB of data from the company. This attack caused significant disruptions in the US healthcare system, preventing doctors and pharmacies from filing claims. Pharmacies, in particular, were affected heavily, as they could not process insurance claims or accept discount prescription cards, forcing some patients to pay full price for medications.

The BlackCat (aka ALPHV) ransomware gang carried out the attack, using stolen credentials to log into the company’s Citrix remote access service, which lacked multi-factor authentication. UnitedHealth eventually paid a ransom demand, allegedly $22 million, to the ransomware gang, which was supposed to be split with an affiliate who conducted the attack. However, the BlackCat operation shut down and kept the entire payment for themselves.

The angered affiliate announced that they still possessed Change Healthcare’s data and had not deleted it as promised. They began leaking some of the stolen data on the RansomHub data leak site, demanding additional payment to prevent further releases. Eventually, the entry for Change Healthcare disappeared from the RansomHub website, suggesting that United Health may have paid a second ransom demand.

United Health estimates that the Change Healthcare ransomware attack has caused $872 million in losses as of April, a figure that will likely increase once all investigations and remediations are completed.

As an IT services provider focused on cybersecurity, we understand the importance of protecting sensitive data and staying informed about the latest threats. The Change Healthcare ransomware attack is a stark reminder of the need for robust security measures and education on potential risks.

Shopify Debunks Hacking Claims, Exposes Stolen Data Connection to Third-Party App

Shopify has denied being hacked after suspicious emails were sent to customers, blaming a third-party app for the data breach. The firm’s investigation revealed that the app had accessed and stolen data from Shopify’s API, but the incident was not a security breach of the platform itself.

Published

Shopify, the popular e-commerce platform, has recently denied experiencing a data breach after a threat actor started selling customer data that they claimed to have stolen from Shopify’s network. But, don’t worry, it’s not as bad as it seems.

What Shopify had to say

According to Shopify, the company’s systems have not suffered a security incident. They told us, “The data loss reported was caused by a third-party app. The app developer intends to notify affected customers.

This statement comes after a threat actor, known as ‘888’, began selling data they claimed was stolen from Shopify back in 2024.

What’s in the data?

The threat actor shared data samples that include a person’s Shopify ID, first name, last name, email, mobile number, order count, total spent, email subscription, email subscription date, SMS subscription, and SMS subscription date. While this information is significant, it’s important to remember that Shopify itself wasn’t directly breached.

Unfortunately, Shopify did not provide any further information about the app from which this customer’s data was stolen.

A history of data leaks

The threat actor, 888, has been linked to previous data sales or leaks allegedly involving companies like Credit Suisse, Shell, Heineken, Accenture India, and Unicef.

It’s also worth noting that in 2020, Shopify disclosed that two “rogue members” of its support team accessed customer transactional records of about 200 merchants. While this is concerning, it’s essential to recognize the proactive steps the company has taken to address security issues.


Stay informed and protect your data

While this particular incident doesn’t seem to be a direct breach of Shopify’s systems, it’s still a reminder to stay vigilant when it comes to our data. Make sure to stay informed about potential threats and take the necessary steps to protect your personal information.

Hackers Expose Supposed Taylor Swift Tickets, Intensify Ticketmaster Blackmail with Power Word

Hackers have leaked alleged Taylor Swift concert tickets and intensified their extortion efforts against Ticketmaster. The group, known as REvil, is demanding a $10 million ransom for the stolen data and threatening to reveal more.

Published

on

Imagine being a die-hard Taylor Swift fan, eagerly awaiting her next concert, and then finding out that your ticket information has been compromised. Well, that’s precisely what happened to a large number of fans recently when hackers leaked the barcode data of 166,000 Taylor Swift Eras Tour tickets. The hackers have warned that more events will be leaked if a $2 million extortion demand isn’t met.

Back in May, a notorious threat actor named ShinyHunters started selling data on 560 million Ticketmaster customers for $500,000. Ticketmaster later confirmed the data breach, stating it was from their account on Snowflake, a cloud-based data warehousing company they use to store databases, process data, and perform analytics.

By April, threat actors had begun downloading Snowflake databases of at least 165 organizations using credentials stolen by information-stealing malware. They then blackmailed these companies, demanding payment to prevent the data from being leaked or sold to other threat actors. Companies known to have had data stolen from their Snowflake accounts include Neiman Marcus, Los Angeles Unified School District, Advance Auto Parts, Pure Storage, and Satander.

When Concert Dreams Turn into Nightmares

Today, a threat actor known as Sp1d3rHunters has leaked what they claim is the ticket data for 166,000 Taylor Swift Eras Tour barcodes used to gain entry on various concert dates.

Sp1d3rHunters, previously named Sp1d3r, is the threat actor behind the sale of data stolen from Snowflake accounts, publicly extorting the various companies for payments. The extortion demand, shared by threat intel service HackManac, reads, “Pay us $2million USD or we leak all 680M of your users’ information and 30 million more event barcodes, including more Taylor Swift events, P!nk, Sting, Sporting events F1 Formula Racing, MLB, NFL, and thousands more events.”

The post claims the barcode data is for upcoming Taylor Swift concerts in Miami, New Orleans, and Indianapolis. It includes a small sample of the alleged barcode data, containing the value used to create a scannable barcode, seat information, the face value of tickets, and other information. The threat actor even shared details on how to turn this data into a scannable barcode.

While the barcode data wasn’t part of the initial leak of stolen Ticketmaster data samples released by the threat actors in May, some of the newly leaked data can be found in the older leaks, including the hashed credit card and sales order information for the tickets.

The group behind these attacks is ShinyHunters, which has been responsible for many data breaches over the years. These include leaking the data for 386 million user records from 18 companies in 2020, an AT&T breach impacting 70 million customers, and most recently, the leaking of 33 million phone numbers used with the Authy multi-factor authentication app.

Update: Ticketmaster has informed us that unique barcodes are updated every few seconds, so the stolen tickets cannot be used. “Ticketmaster’s SafeTix technology protects tickets by automatically refreshing a new and unique barcode every few seconds so it cannot be stolen or copied,” Ticketmaster told us. “This is just one of many fraud protections we implement to keep tickets safe and secure.” They also confirmed that they did not engage in any ransom negotiations with the threat actors, disputing ShinyHunter’s claims that they were offered $1 million to delete the data.
