Lloyds Banking Group fell victim to a 48-hour online attack that was finally resolved on Friday, January 13. In a ploy affecting 20 million accounts, cybercriminals bombarded the bank with millions of fake requests in order to jam online services. This is not a new trick; cybercriminals have been doing it for years and then asking ransom to be paid in Bitcoin. This time, however, Lloyds paid no ransom, and no accounts appear to have been hacked or compromised. During the outage, Lloyds’ security technologists played a game of cat-and-mouse with the cybercriminals. The strategy, known as geo-blocking, is described as dropping a portcullis over the offending server as soon as it was identified; at which time the perpetrator would move to another server. This kept the problem roving for two days, affecting only a small percentage of customers at any given time, but also interfering with legitimate transactions attempted on the affected servers. The Lloyds hack has spurred a call for merging all the nation’s cybersecurity forces, in the name of achieving higher levels of scrutiny and accountability.
