T-Mobile is the latest in the list of recent high-profile data breaches, though this time the breach is not carried out by "Peace" - the Russian hacker who was behind the massive breaches in some popular social media sites including LinkedIn , MySpace , Tumblr , and VK.com . Instead, one of the T-Mobile's employees stole more than 1.5 Million customer records at the T-Mobile Czech Republic in order to sell it on for a profit, according to local media , MF DNES. Yes, the customer service staff member tried to sell the T-Mobile customer marketing database, though it is not clear that how much of names, e-mail addresses, account numbers and other personal data of over 1.5 Million customers the database contained. The T-Mobile Czech Republic has also refused to provide any "additional specific information" about what data was leaked, due to an ongoing police investigation.

How many more data dumps does this hacker have with him that has yet to be exposed? Well, no one knows the answer, but we were recently made aware of another data breach from Peace – the same Russian hacker who was behind the massive breaches in some of the most popular social media sites including LinkedIn , MySpace , Tumblr , and VK.com . The hacker under the nickname "Peace" (or Peace_of_mind) is now selling over 51 Million records obtained from iMesh – now defunct peer-to-peer file sharing service. The New York-based iMesh was one of the first and most popular file sharing services that allowed users to share multimedia files with their friends via the peer-to-peer (or P2P) protocol. Launched in the late 90s, iMesh became the third-largest service in the United States in 2009, but the service was unexpectedly closed down last month. LeakedSource, a search engine site that indexes leaked login credentials from data breaches, noted in a blog post that the comp

The hacker, nicknamed Peace, who is selling the database of about 360 Million Myspace accounts with 427 million passwords, is the same hacker who was recently in the news for leaking 164 Million LinkedIn and 65 Million Tumblr accounts .

Using Tumblr app on iPhone ? Reset you Tumblr password now

Tumblr posted a blog post Tuesday night warning users to change their passwords and released a very important security update for iOS users after identifying a breach that compromised their passwords. It seems that, under certain circumstances, the prior versions of the iPhone and iPad apps would allow an individual with malicious intent to sniff or intercept passwords as they are in transit across a local network. The problem arose because the iPad and iPhone apps fail to log users in through a secure server.  The vulnerability does not seem to have affected Tumblr’s Android app. The company urged users to download the latest version of the Tumblr app, which is available in the Apple iTunes Store. The company did not provide further details on the breach. It’s also good practice to use different passwords across different services by using an app like 1Password or LastPass. It doesn’t appear that any passwords got in the hands of malicious individuals, though you

We believe that the hacker downloaded email addresses of users who contacted those three customers for support, as well as support email subject lines.
