Apparently eight databases of 60M records of LinkedIn user information has been compromised. Some of this data may be already be public information but info such as profile, email addresses of the LinkedIn users has been revealed. This is from a Bleeping Computer security article:
“Eight unsecured databases were found leaking approximately 60 million records of LinkedIn user information. While most of the information is publicly available, the databases contain the email addresses of the LinkedIn users.
Approximately two weeks ago, I was contacted by security researcher Sanyam Jain of the GDI foundation about something strange that he was seeing. Jain told BleepingComputer that he kept seeing unsecured databases containing the same LinkedIn data appearing and disappearing from the Internet under different IP addresses.
Between all eight databases, there was a combined total of approximately 60 million records that contained what appeared to be scraped public information of LinkedIn users. The total size of all of the 8 DBs is 229 GB, with each database ranging between 25 GB to 32 GB.
In addition to the above public information, each profile also contains what appears to be internal values that describe the type of LinkedIn subscription the user has and whether they utilize a particular email provider. These values are labeled “isProfessional”, “isPersonal”, “isGmail”, “isHotmail”, and “isOutlook”. While we not able to determine who the database belonged to, we were able to contact Amazon who is hosting the databases for assistance in getting them secured. As of Monday, the databases were secured and are no longer accessible via the Internet.”
