John: If you are careful enough,  you would find that 80% of my case are live and on-the-site surveillance. 

Me: I noticed that long time ago. 

John: Good. I give you guys an example of live and on-the-site eavesdrop.  It happen in 2010.

.

While (telecom is running)

{

if (dial = John)

{

Bind (physical address, the person to be called );

.

Bind (physical address, Mr. Gao ); <--- Mr. Gao hack the telecom and add an extra code here.

}

else

{

Bind (physical address, the person to be called );

}

}

.

Mr. Gao (a Kelvin's deputy in China):  It's a live and on-the-site eavesdrop. Do you hear that John's client say to him, "You are always late. "?

Miss Ho (It's only an assumed name. In fact,  I don't know her name): Yes,.

Mr. Gao: After John hang up the telephone. You call John. You pretend to be a potential client.  You say to John, "Ha, Ha, Ha, I am an easy -going client. I don't mind your unpunctuality".

John: 1 minute after I hang up the telephone,  Miss Ho gave me a phone-call and she said that to me.

Me: 1 minute ?

John: Yes,

Me: It's is live and on-the-site eavesdrop. 

.

___

.

John: Correct.  The eavesdrop occurred at 1500pm of Hong Kong.  1500pm of Hong Kong is 0300am of New York. 

.

Me: Kelvin is a New Yorker.  You're a Hong Konger.  At that time,  Kelvin should be on his bed sleeping.  He couldn't be awake eavesdropping on you guys. 

.

John: Correct. So,  I say the eavesdrop is done by Mr. Gao.  The eavesdrop isn't done by Kelvin.  Mr. Gao stay in Beijing.  Beijing is at the same time zone of me. 

.

Me:  To hack the telecom,  we need a machine to create a signal.  This signal can penerate the server of the telecom. 

.

John: This machine must be in New York.  It can't be in Beijing.  

.

Me: So,  what did happen ?

.

John: In fact,  Miuson gave a hacker's package to Mr. Gao.  When Mr. Gao press a button,  a signal go from Mr. Gao's computer of Beijing to a super machine in New York.  And then,  this super machine on behalf of Mr. Gao send a very destructive signal to the server of telecom.
