British Airways hit hard

British Airways hit hIn this age, credit cards are required for many aspects of our culture. To rent a car, hotel room, or purchase airline tickets, a credit or debit card is required. To purchase these services without a credit card is problematic. One airline providing the travel service is British Airways, a major international airline. Unfortunately, the airline system was breached. This affected 380,000 credit card payments. These were used on the British Airways website and mobile app in August 2018. British Airways did contact the affected parties on September 7, 2018. Considering the large number of affected parties, a number of questions of attack methodology arise. The attackers must have had a clear and in-depth penetration into their system.

Attack

With this attack and compromise, investigators were able to note when, including the time, the attack occurred. During August 21, 2018 (10:58p) through September 5, 2018 (9:45p), the company’s website and mobile app were successfully attacked and breached. Curiously, BA stated this was a data theft, versus calling this a breach. This may indicate this was an internal threat versus originating from a third party.

Data

The attackers could have targeted a variety of data based on the attack and potential points to pivot from. The attackers were able to access valuable data with the customer’s name, address, email addresses, credit card expiration dates, and other credit card details, including the CVV code. Fortunately for the affected parties, the attackers were not able to exfiltrate the customer’s passport data.

Vulnerability

Throughout several industries, web applications tend to be a valid, robust attack point. This is due to security not being included through the process, new vulnerabilities, and insecure coding, among other issues. BA did remediate the vulnerability.

With these issues, it would be beneficial to know exactly what the vulnerability exploited was, or if there were multiple, what these were. In this case, others could learn from the oversights so that these errors would not be done repeatedly by others in the same and other industries. Unfortunately in this case, BA had refused to answer any further questions relating to the breach.

Through the issue, BA worked with cybersecurity firms through the forensic review period. The attack period itself is notable. The attackers had over two weeks of full access. Perhaps the SIEM did not detect the compromise in a timely manner, or the logs and reports were not examined at length. This was too long for the compromise, which increased the number of their clients affected by this.

Lessons

The information security teams should have detected this individually or through their tools in place on the systems. The data should have been reviewed prior to the time this was. This is a lesson for others, not only in the airline industry. The logs should be regularly reviewed for anomalies and other unusual activities. Resources
