National Australa Bank impacted by law firm cyber breach

The National Australia Bank (NAB) was one of the clients of law firm HWL Ebsworth whose information was compromised in a cyberattack in April.

The attack resulted in the breach of approximately 1.4 terabytes of data, including hundreds of thousands of client documents.

While NAB's internal IT systems remained uncompromised, the breach is expected to primarily impact specific legal matters in which NAB engaged HWL Ebsworth for advice and representation.

The leaked information includes sensitive documents spanning up to 20 years, along with personal data such as driver's licenses. HWL Ebsworth obtained an injunction to restrict access to and dissemination of the leaked information, which obviosly won't do absolutely any good to the victims since criminals are not in the business of respecting court injunctions.

The ransomware group responsible, known as BlackCat o attempted to extort the law firm and publicly released a portion of the stolen data when their demands were not met.

HWL Ebsworth is conducting a review of the compromised data and collaborating with relevant authorities to notify affected parties and provide support.
