“HSBC Bank is warning some of its U.S. customers that their personal data was compromised in a breach, although it says it’s detected no signs of fraud. The data breach affects only the U.S. operations of London-based HSBC, which is the world’s seventh largest bank and the biggest in Europe. HSBC says the breach appeared to run from Oct. 4 to Oct. 14. After spotting the breach, the bank says in a notification announcement, it “suspended online access to prevent further unauthorized entry” to affected accounts.”
