Data belonging to 2,5 million members of the two gaming forums hacked in 2015 is freely circulating online. In 2015, two gaming forums XBOX360 ISO and PSP ISO were hacked. Both forums helped players gain access to illegal copies of Xbox games and PlayStation.
According to the information available, PSP ISO was violated in September of 2015, and nearly 1,3 million emails (email, hashed passwords and IP addresses were leaked) Xbox 360 ISO was violated for about the same time period, exposing 1,2 million accounts (email, IP address, password hashes).
Of course no one knows who or who is behind the hack. However, the above information is available online, and it would be good if you had one account on the specific websites to change passwords. You should also be especially careful of attacks Phishing.
But we must say that in order to freely circulate the data, it probably will not be of any value to hackers who have probably already used the information. Moreover, it has been a long time since the violation and most users have already taken some precautionary measures.
Troy Hunt, founder of Have I Been Pwned, a website where you can enter your email address and see if there is any information from hacked lists data, states that none of the leaked information was encrypted.
"Both forums used hashes (which are not encryption!) To store passwords, but they used a very weak algorithm making encryption almost useless."
