Transak, a cryptocurrency on-ramp firm, has reported a data breach that has affected 92,000 users. The breach was the result of a phishing attack that targeted an employee's laptop, leading to the exposure of sensitive Know Your Customer (KYC) data. A ransomware group has claimed responsibility for the attack. In a separate incident, Hot Topic, a retail company, is facing what is being described as the largest retail data breach in history, with personal and payment data of 350 million customers exposed due to an infostealer infection. Investigations revealed that the breach occurred after hackers targeted an employee at a third-party retail analytics platform, allowing them access to the sensitive information.
