Millions of Facebook, Twitter and Google passwords stolen in hack Hackers have stolen the details to millions of online users, including the passwords to Facebook, Twitter and Gmail accounts. THE passwords of nearly two million Facebook, Twitter, Gmail and LinkedIn users have been stolen in a massive hack that has occurred over the past month. Researchers at a cybersecurity company called Trustwave have found that a virus is capturing login details for some of the internet's biggest websites including Facebook and Gmail, reports CNN . More than 93,000 sites have been compromised and Trustwave has made its research public showing the following, rather worrying, results of account details stolen: 318,000 Facebook accounts 70,000 Gmail, Google+ and YouTube accounts 60,000 Yahoo accounts 22,000 Twitter accounts 8,000 LinkedIn accounts See the other websites that have been hacked, here Hackers have been able to obtain the details by using "keylogging software," which is a virus that installs itself onto "an untold number of computers around the world." How the virus has managed to work its way onto so many computers is unknown, but Trustware believe it might be "ongoing." Trying to find the virus on your computer could prove tricky too as the virus is "running in the background," said John Miller, a Security Research Manager at Trustware. The article confirms that Facebook, LinkedIn and Twitter have "notified and reset passwords for compromised users" however Google has "declined to comment." If you've had your details hacked, check out our three-step plan to what to next: Change your password. A bit of a no-brainer, but this is your first priority. Good tips for a strong password include something that should be long (Microsoft recommends at least eight characters), contains a mixture of upper and lower case plus numbers, and should be changed regularly. To check if your password has been compromised you can check at shouldichangemypassword.com Assess the damage. Have a look around your account to see whether there has been any unusual activity. Look through your Sent Items folder to see if any spam has been sent from your account and let your contacts know what has happened to prevent their systems being compromised. Also check your settings to see if any emails you receive are automatically being forwarded - this is a sneaky way hackers get to see all of your emails. If you think your bank details have been stolen check your account activity and call the bank. Check you have anti-virus software. If you don't, go get yourself covered. You can buy anti-virus software from shops or download online. There are plenty of decent free options available. If you have anti-virus software already installed see if there are any updates you can run.
