A security vulnerability in AlphaBay, one the most popular black marketplaces, could expose private messages and data of its users. Access to private messages could reveal sensitive information sales and negotiations conducted by users. AlphaBay launched an API that allows its users to pull details from their accounts without logging last week. An API key was used to scrape the data and only 1 or 2 people have accessed the data. The manager of the black market confirmed that only old messages were accessed by the people. Others are concerned that law enforcement may have quickly exploited the vulnerability to access a wealth of messages.”]
