The Twitter account of PayPal in the UK was hacked late Tuesday and used to post angry comments about the quality of service and security mechanisms underlying the business.
The account was suspended Tuesday evening, after an anonymous hacker took control of the tweet stream, with an initial message reading: "Our security is so great, look at our Twittter feed and see!".
Later Tweets directed users to the website paypalsucks.com, that that aims to expose "the nightmare of doing business" through PayPal.
PayPal resumed control of the account overnight and deleted the bogus tweets from its stream.
In a statement, the company sought to reassure customers that its systems and data have not been breached or hacked: "There is no link between customer systems and our Twitter account."
The incident follows the takeover of the Fox News Twitter account by the Anonymous collective of hackers, who used it to falsely claim that Barack Obama had been shot and killed on the 4 July.
