Hackers allegedly breached HSBC USA and stole customers’ records, including bank account numbers and transaction details. A threat actor posted screenshots and data samples on a dark web leak forum. The alleged stolen database contains names, addresses, Social Security numbers (SSNs), dates of birth, phone numbers, email addresses, transaction histories, stock orders, and bank account numbers.
Researchers who analyzed the provided sample suggest the data may be legitimate and appear recent. HSBC has acknowledged a recent denial-of-service (DoS) attack, but the bank denies any customer data was accessed or lost.
Ignas Valančius, Head of Engineering at the cybersecurity company NordPass, comments:
“If true, this could be one of the most dangerous attacks in recent years. We have seen a lot of cyber incidents recently in the retail, aviation, and automotive industries. However, these were primarily related to ransom demands and mostly impacted breached companies. Some of them were even forced to stop their activities. In this alleged attack on HSBC USA, personal customer data could have been stolen along with financial information. Similar cases proved that from there, it’s only a small step to financial fraud — or, even worse, identity theft.”
“The data hackers allegedly obtained allow malicious actors to empty accounts, take out loans, open fraudulent accounts, file fake tax returns, or use the stolen personal information for further fraud or cyber attacks, such as spearphishing. Attackers could also attempt to use the data to impersonate legitimate institutions.”
“If we look at cold numbers only, the financial impact of this attack will likely be noticeably lower than those of some recent, widely discussed incidents, like the Jaguar Land Rover incident. However, the attack on HSBC may result in personal tragedies and cyber harassment for businesses that had used HSBC services.”
“HSBC, ranked among the biggest banks in the world, has been reducing its retail banking operations in the US and focusing on corporate clients recently. It has largely exited the U.S. mass retail banking sector. As a result, the retail data might be older than the hackers claim. Regardless, it would be prudent for all bank customers, both business and private, to change their passwords and activate multi-factor authentication (MFA) on online banking platforms and apps if they have not done so already. I would also advise to maintain heightened vigilance for phishing emails. After such attacks, phishing, spearphishing, CEO fraud, and other social engineering attacks typically increase.”
This is potentially a scary hack. This will need to be watched closely as the fallout from this could be massive.
