The Diffie Hellman (DH) implementation uses weak keys that are unsafe for DH handshakes. As a result, if a Tor client routes via a Tor server that is a malicious server and the malicious server is the first server, the malicious server can learn all of the keys negotiated for the remainder of the circuit. The server can also spoof the entire circuit. This allows the server to access the target user's traffic. Impact: A client can lose confidentiality and integrity for Tor-routed connections. http://www.securitytracker.com/alerts/2005/Aug/1014739.html

SMS spoofing is emerging as a menace and might hamper the growth of the mobile industry. For the uninitiated, with SMS spoofing a cyber criminal can send an SMS to anyone on the cell phone without touching it. This also implies that if the person (who receives the message) goes to the reply mode of the phone and writes any reply text after receiving the spoofed SMS, it will again come back to the same person. This has serious security ramifications and the scope or misuse is enormous http://www.crime-research.org/news/08.19.2005/1440/
