Mark Zuckerberg’s social networking giant Facebook has launched a .onion URL, by which users can refrain from revealing identities online. It has been a historic move for the company, as it has always had genuinely registered users in the near past. Alec Muffett, Facebook’s computer software engineer for safety infrastructure blogged saying, “The internet users who use the Tor browser to shield their anonymity can now visit Facebook by means of a particular .onion address.”
Tor stands from The Onion Router. It has been designed in a way that users would get better privacy. People who want to refrain from revealing IP address can use this system, along with those in countries where the site has been officially blocked by various governments.
According to Muffet, Tor may also be problematic for Facebook, he says, “Tor challenges some assumptions of Facebook’s security mechanisms—for example its design means that from the perspective of our systems a person who appears to be connecting from Australia at one moment may the next appear to be in Sweden or Canada. In other contexts such behavior might suggest that a hacked account is being accessed through a ‘botnet’, but for Tor this is normal”.
Muffet also added in the most that the idea was to let people connect with a direct browser connection into Facebook’s data center. “Facebook’s onion address provides a way to access Facebook through Tor without losing the cryptographic protections provided by the Tor cloud,” he said.
