Online hacking group Anonymous is targeting Adidas and other World Cup sponsors ahead of the football competition’s kick off this week.
The group is threatening to attack the sports giant along with other sponsors Budweiser, the Coca-Cola Company and Emirates Airline in protest against the amount of money spent on the event.
Anonymous argues Brazil should spend its money on general infrastructure and public services rather than the World Cup.
Last week, Anonymous broke into the systems of Brazil’s Foreign Ministry and leaked a number of confidential emails. A government spokesman said only 55 email accounts had been hacked, and only the ministry’s internal document archive was accessed.
Network security specialist Radware estimates around £13,400 is lost every minute during a service attack.
It has advised companies to carry out network scanning and investigate every attack, as there could be smaller test attacks before a larger scale hack is deployed.
Last month footwear retailer Office advised customers to change their passwords on the website after details were accessed by hackers.
Customer names, addresses, email addresses, birth dates, phone numbers and Office account passwords were among the details hacked. However no credit card, debit card, Paypal or bank details were compromised in the attack.
