British Airways faces Data Breach of 380,000 Accounts

September 18, 2018

A malicious JavaScript code had been planted within British Airway’s website, leading to data breach of around 380,000 accounts.

 

 

RELEASE DATE: September 14th, 2018

 

 

INCIDENT

 

 

Starting from August 21st, around 380,000 accounts have been compromised in a major data breach of British Airways, revealing customers’ information. Cybersecurity organization RiskIQ believes that the Magecart attackers were involved in the breach, who have previously been associated with the Ticketmaster UK breach, earlier this year.

 

The attackers were successful in obtaining names, street and email addresses, credit card numbers, expiry dates and security codes of the airline’s customers, which could potentially lead to theft from user accounts.

 

British Airways informed that all the payment information processed through the airline’s website and mobile app between August 21st and September 5th had been exposed.

 

 

ATTACK VECTOR

 

 

The evidence reveals that a malicious JavaScript code had been planted within British Airway’s website.

 

Magecart has traditionally stolen data by injecting the malicious script into payment forms.

 

RiskIQ further informed that hackers used only 22 lines of code to get a hold of the data. (attached below)

 

 

 

The attack compromised British Airways’ own Web server, making it a highly targeted attack that aimed for this particular website and its mobile Application.

 

“This skimmer is attuned to how British Airways’ payment page is set up, which tells us that the attackers carefully considered how to target this site in particular.” Yonathan Klijnsma, head researcher at RiskIQ said.

 

 

ROOT CAUSE

 

 

The Magecart’s association with the attack was identified because the attack is web-based and targeting credit card data. The attackers focused on the unique site structure and functionality of the British Airways website and exploited their security lapses. RiskIQ crawled the scripts on the British Airways’ site and traced how they changed over time. During the process, the researchers found a modified script in the compromised site.

 

The BA site is found to be utilizing a JavaScript library called an API, on a malicious Web server at baways.com. It’s a virtual private server hosted by a provider in Lithuania, using a TS certificate registered through Comodo (to appear legitimate) on August 15. The code was injected through the JavaScript library.

 

When a customer enters information on the website’s payment form and clicks “submit”, the 22-lines of code export the entered data to the malicious server as a JSON object.

 

The customer’s transaction is not disturbed and appears to be over a secure session while the attackers receive a full copy of the payment information. The attackers also added a “touchend” callback to the script, extending the attack to BA’s mobile App as well, which also called the same modified script.

 

 

LESSON LEARNED

 

 

The British Airways website seems to be operating without visibility into its Internet-facing web assets. Therefore, the British Airways could not detect this compromise and data breach until it was too late.

 

With so many attack vectors and ever-increasing techniques of cyber-attacks, organizations should make sure that they have an intact cybersecurity implementation. With proper measures, visibility and regular penetration testing, such attacks can be nipped in the bud before they cause any damage.
