In September 2007, Dan Egerstad, a Swedish security consultant, revealed that he had intercepted usernames and passwords for a large number of email accounts by operating and monitoring Tor exit nodes.[26] As Tor does not, and by design cannot, encrypt the traffic between an exit node and the target server, any exit node is in a position to capture any traffic passing through it which does not use end-to-end encryption such as TLS. While this may or may not inherently violate the anonymity of the source if users mistake Tor's anonymity for end-to-end encryption they may be subject to additional risk of data interception by self-selected third parties.[27] (The operator of any network carrying unencrypted traffic, such as the operator of a wi-fi hotspot or corporate network, has the same ability to intercept traffic as a Tor exit operator. End-to-end encrypted connections should be used if such interception is a concern.) Even without end-to-end encryption, Tor provides confidentiality against these local observers which may be more likely to have interest in the traffic of users on their network than arbitrary Tor exit operators.
