Transactions are processed through a centralized Escrow system to protect buyers at all times. When a transaction is started, the funds are temporarily held in the Escrow system until the buyer acknowledges receipt of the goods. The marketplace also offers a decentralized multi-signature system, where the private keys are released to the seller upon finalization. On March 28, 2015, AlphaBay Market made the news for selling stolen Uber accounts.〔(【引用サイトリンク】title=Stolen Uber Customer Accounts Are for Sale on the Dark Web for $1 )〕〔(【引用サイトリンク】title=Stolen Uber accounts on sale for $1 each )〕 Uber sent a statement regarding a potential data breach: "We investigated and found no evidence of a breach. Attempting to fraudulently access or sell accounts is illegal and we notified the authorities about this report. This is a good opportunity to remind people to use strong and unique usernames and passwords and to avoid reusing the same credentials across multiple sites and services." In May 2015 the site announced an integrated digital contracts and escrow system. The contract system allows users to make engagements and agree to provide services in the future, according to the terms of the contract. In October 2015, the London-based telecommunications company TalkTalk suffered a major hack.〔(【引用サイトリンク】title=TalkTalk hacked in significant and sustained cyberattack )〕 The stolen data was put for sale on Alphabay Market, which led to the arrest of a 15-year old boy.〔(【引用サイトリンク】title=TalkTalk breach: CEO dismisses encryption, 15-year-old arrested )〕 TalkTalk CEO Dido Harding issued the following statement: "TalkTalk constantly updates its systems to make sure they are as secure as possible against the rapidly evolving threat of cyber crime, impacting an increasing number of individuals and organisations. We take any threat to the security of our customers' data extremely seriously and we are taking all the necessary steps to understand what has happened here." The UK-based media outlet DailyMail pointed that the marketplace might be linked to the Russian mafia.〔(【引用サイトリンク】title=TalkTalk customers bank details stolen in massive online hack are already up for sale at £1.62 a time )〕 According to the UK-based media outlet Daily Mirror, "It is administered in Russia and has a Russian computer server.
