No data is safe, as the leaks by “Peace_of_mind,” the hacker responsible for the breaches of sites like LinkedIn and Tumblr, continue. The latest victim? iMesh, a P2P file sharing service.

According to LeakedSource, which indexes leaks from data breaches, over 51 million iMesh accounts were compromised in this latest attack, which was revealed shortly after an unexpected shutdown last month. However, given the age of the information, it is unlikely the two events are connected.

Among the information are email addresses, passwords, IP addresses, and location information. The passwords were stored in hashed and salted format, but the MD5 algorithm it used is easily breakable.

The records contain information from September 2013 and earlier, so like many of the other breaches, it’s an older one that was not revealed until now. Users who signed up after October 2013 should be safe, and users who changed their passwords after that time are also in the clear, but should take care to make sure any other passwords connected to their email addresses are safe.

Reports from The Hacker News indicate that the information has been put for sale on The Real Deal Dark Web marketplace, the same site and from the same seller as the recent social network data breaches, priced at half a Bitcoin (or approximately $335).

While this information may be old, it’s still a lot of data, compromising millions of accounts from countries around the world. If you’ve ever used iMesh to share files with friends, you may have ended up sharing much more than intended.
