A wave of social media sites were yesterdayÂ hit by a cyber-attack as software giant Microsoft also admitted they had beenÂ breached in ‘a similar way’ to recent incidents at Facebook and Apple.
Twitter, Tumblr and virtual clipboard siteÂ Pinterest all admitted they had been hit yesterday, writing to users to tellÂ them their personal data had been breached.
Microsoft also chose to report a past attackÂ yesterday but would not say on what date the breach took place.
The world’s largest software company said itÂ hit only internal computers and didn’t have any impact on customers details.
They said they wouldn’t report the date forÂ security reasons but admitted it had similarities in style to attack experiencedÂ by Facebook and Apple earlier this month.
‘Consistent with our security responseÂ practices, we chose not to make a statement during the initial informationÂ gathering process. During our investigation, we found a small number ofÂ computers, including some in our Mac business unit, that were infected byÂ malicious software using techniques similar to those documented by otherÂ organizations. We have no evidence of customer data being affected and ourÂ investigation is ongoing.’
‘This type of cyber-attack is no surprise toÂ Microsoft and other companies that must grapple with determined and persistentÂ adversaries.’
The three social media websites were hit byÂ an attack on a customer service program used across them allÂ yesterday.
They were forced to warn users that theirÂ details could have been leaked following the breach at Zendesk which operatesÂ its email exchange with customers.
Zendesk said it was hacked for users emailÂ addresses and subject lines.
‘We believe that the hacker downloaded emailÂ addresses of users who contacted those three customers for support, as well asÂ support email subject lines,” Zendesk said.
Affected users of all three sites wereÂ contacted and reminded to keep their passwords strong and told to check whetherÂ any sensitive information was mentioned in email exchanges with the websitesÂ which would have been conducted via Zendesk.Â Â
‘We recently learned that the vendor we useÂ to answer support requests and other emails (Zendesk) experienced a securityÂ breach,’ a warning email by Pinterest said.
‘We’re sending you this email because weÂ received or answered a message from you using Zendesk. Unfortunately your name,Â email address and subject line of your message were improperly accessed duringÂ their security breach.’
Facebook and Apple both revealed they hadÂ been hit earlier this month.
Apple said some of its internal computersÂ were infected by malware but no data was stolen.
Facebook suffered an intrusion they describedÂ as a ‘sophisticated attack’ but said they did not believe user data wasÂ compromised.
It said in a blog post on February 15:Â ‘Facebook was not alone in this attack. It is clear that others were attackedÂ and infiltrated recently as well. As one of the first companies to discover thisÂ malware, we immediately took steps to start sharing details about theÂ infiltration with the other companies and entities that were affected. We planÂ to continue collaborating on this incident through an informal working group andÂ other means.’
Earlier in the month Twitter reported aÂ hacking attempt which could have exposed details of up to 250,000 users.
