Credit Suisse, a global investment bank and financial services firm, has reportedly fallen victim to a cyberattack. The Credit Suisse data breach was allegedly masterminded by a threat actor (TA), operating under the alias “888,” on the data hack site BreachForums. The TA claims to have accessed highly sensitive data of the bank and posted it on the dark web marketplace. According to the the threat actor, the data breach contains personal information of about 19,000 of the bank’s Indian employees.

Credit Suisse Data Breach Details

Credit Suisse was founded in 1856 and has approximately $15.21 Billion in revenue. It is one of the leading institutions in private banking and asset management, with strong expertise in investment banking. On June 25, 2024, the threat actor claimed to have carried out a cyberattack on the bank and exfiltrated details on 19,000 of its users.

To substantiate the claim, the threat actor 888 provided a sample of the data breach, which contains details of Credit Suisse employees in India.

The hacker commented that they are only accepting cryptocurrency as the mode of payment. More specifically, the hacker was open to payment on Monero (XMR), a digital currency renowned for its privacy and anonymity attributes. This method of payment is often utilized in illegal transactions to evade detection. Despite these claims by the threat actor, a closer inspection reveals that the bank’s website is currently functioning normally, showing no signs of a security breach. The Cyber Express has reached out to the bank to verify the alleged cyberattack. As of now, no official statements or responses have been received, leaving the claims unverified.

Not the First Credit Suisse Data Breach

This is not the first time that Credit Suisse has been involved in a security breach. According to a report published in The Economic Times, in 2023, the bank warned its staff that a former employee stole personal data of its employees, including salaries and bonuses. The information included salary and "variable compensation" for a period between 2013 and 2015. Another Bloomberg report said that a data breach in 2023 impacted numerous former Credit Suisse clients who collectively held a staggering $100 billion in accounts.

Credit Suisse Hacker Targeted Big Multinationals Recently

There are many concerns over the potential misuse of sensitive information found in the data breach, which includes customer names, dates of birth, and relationships. Credit Suisse should investigate the data breach claims considering the history of the threat actor. Earlier this month, the TA 888 claimed to have stolen data of over 32,000 current and former employees of Accenture. The company, however, denied the claims and said that the data set published by the hacker had only three employee names and email addresses. The hacker also claimed responsibility for leaking details about 8,174 employees of Heineken across several countries. Prior to this, 888 also staked claims for an attack on oil and gas multinational Shell.  The TA posted sample information sharing personal details of Australian customers.
