Dealers of Jet Engines to Major Airlines Reveals 'Unauthorized Activity'

 

The Willis Lease Finance Corporation has disclosed to US regulators that it was targeted in a "cybersecurity incident," with data allegedly taken from the company being shared on the Black Basta ransomware group's leak blog.

In a filing submitted to the Securities and Exchange Commission (SEC) on February 9, the publicly listed company on NASDAQ stated that it became aware of a potential breach on January 31, prompting immediate action to address the situation.

According to the filing, the company initiated an investigation into the incident with the help of leading cybersecurity experts, taking measures to contain and address the activity, including temporarily shutting down certain systems. The company reported no unauthorized activity after February 2, 2024, and believes it has successfully contained the breach.

During the period when systems were offline, the company acknowledged resorting to alternative methods to maintain operations and serve customers, although specific details were not provided.

Willis Lease Finance also stated it is still evaluating the extent of the breach and whether any data was compromised. Law enforcement has been notified about the breach.

Although the company refrained from explicitly mentioning "ransomware" or "attack" in its disclosure, the presence of passport scans on Black Basta's website suggests that the investigation into potential data theft may yield results soon.

The ransomware group claims to have obtained 910 GB of company data, including information about customers, employees, HR records, non-disclosure agreements (NDAs), among others. Black Basta published a selection of documents online, including screenshots of accessed files, HR documents containing social security numbers, and identity documents such as passports.

Attempts to match names on these documents with online profiles revealed matches predominantly in the US and UK, along with some from other countries.

Efforts to reach Willis Lease Finance for comment were unsuccessful at the time of reporting.

Established for over 45 years, Willis Lease Finance describes itself as a leading independent provider of jet engines to major airlines worldwide.

Black Basta, known for its high-profile ransomware attacks, is linked to the now-defunct Conti group and is believed to have amassed over $100 million from its victims, including major organizations like Capita and Southern Water in the UK.
