A disgruntled computer engineer has been sitting in a prison cell for four days after locking out everyone but himself from a city computer system.
Terry Childs is accused of tampering with San Francisco's new computer network to give himself exclusive access. He has refused to hand over the password and is being held on $5 million bail while officials try to crack his code.
The Department of Technology employee, 43, allegedly created a secret password to the city government's data network. The multimillion-dollar network stores records such as officials' e-mails, city payroll files, confidential law enforcement documents and jail bookings.
Mr Childs was arrested last Sunday and is being held on suspicion of four counts of computer tampering. His arraignment is scheduled for later today.
The city says that fixing the system, which hosts 60 per cent of the city government's data, and determining whether the alleged tampering led to a security breach could cost millions of dollars.
At a news conference announcing Mr Childs' arrest, Kamala Harris, the district attorney, said: "This involves compromising a public system that we rely on. Its integrity has been compromised."
The network administrator, who lives in Pittsburg, has been working for the Department of Technology for five years and has a basic salary of just over $126,000. Police said that Mr Childs had recently been disciplined at work. Reports suggest that officials then discovered that Mr Childs had put together a tracing system to monitor what other administrators were saying and doing in relation to his disciplinary case.
Last weekend he allegedly locked out all administrators except himself. Before his arrest he gave pass codes to police, but they did not work. "They weren't able to do it," an official said. "This was kind of his insurance policy."
It was feared that although Mr Childs is in jail, he may have enabled someone else to access the system by telephone or other electronic device and order the destruction of hundreds of thousands of sensitive documents.
Currently documents in the system can be accessed, but if there are problems or the system crashes there is no way to repair the network quickly. Engineers from the technology company Cisco have been brought in to try to gain access.
Gavin Newsom, the mayor of San Francisco told the San Francisco Chronicle: "There is nothing to be alarmed about, save the inability to get into and tweak the system. Nothing dramatic has changed in terms of our ability to govern the city."
He said that Mr Childs had been a highly regarded member of staff but was now a "rogue employee that got a bit maniacal".
It has emerged that Mr Childs has a criminal record for aggravated burglary, for which he served five years' probation in 1982.
"He was very good at what he did, and sometimes that goes to people's heads. We think that is what this is about," Mr Newsom said.
The incident is one of the highest profile cases of what IT security experts call "insider threat". Layers of security and checks are built into companies' computer system to protect against disgruntled and unscrupulous employees trying to gain access to valuable information and sharing it for personal gain, espionage or revenge.

So, what happened to Terry Childs? I hope things went the right way and he is home and all this nightmare is behind him.
And I hope that the crooks leaked secure network passwords into the wild are behind the bars.

A shining example of just how arrogant some of these computer geeks are! No wonder people like this have no friends or partner!
A word of advice matey - there are plenty of people that do understand computers, but only a serious basket case would get all big headed about it.

43? More like 23, no doubt he uses moisturiser.

Its amazing how everyone feels qualified to comment on something that they apparently know oh so very little about. Clearly half the commenters can't tell the difference between a router or a hard drive.
But thank you all for your unintentionally silly comments though. Its been all very funny.

The DA ought to be drafting a deal to exchange his freedom for the codes. But instead they will spend tax dollars and more tax dollars over thier ego issues. The USA loves prisons. Make a deal and settle this thing. Then make sure two admins have the codes from now on. It works for nukes.
Lavinski, Salt Lake City, USA
The USA is one place I would never commit a crime, not that I would anyway, all very dodgy.
Give the guy a slapped wrist like they would in the UK, and not put all your eggs in one basket.
Chris, Earth,
Have they tried rebooting? Sometimes, you know, the password is just the person's name or date of birth! Try loading new sound drivers. Or maybe reinstalling Windows?
If this fails, contact your local dealer.

If Cisco are involved it is the network not the data that is compromised. There are back doors to Cisco equipment if you have physical access to the devices - even if the backdoor has been disabled by Childs it is an inconvenience rather than catastrophe.

Imagine what could be done if some disgruntled whitehall employee decides to take sole control of the DNA database that there creating.

If there's nothing to worry about, why is it taking so long to fix and as importantly. why is his bail $ 5,000,000. Isn't he innocent?
Ben, Las Vegas,
Organizations over the past decades have been concentrating access privileges to 'administrators', on the basis of so-called compliance blah blah blah. Nobody monitors the administrators. Well, now the decision makers can eat their air-headed strategy.

Zeke: Only a small minority of hackers perform "illegal" acts. Most work as consultants legitimately.
I swear the ignorance surrounding computers is astounding. And I sure don't want to hear a politician talking about power going to someone's head.

He locked everyone out of the maintenance account to control the routers in protest of has managers actions. No data is lost and no data is inaccessible to users - so i say GO TERRY! Take a stand for all the IT personnel being abused by management in this world I'm with ya!

An engineer (erm hacker) with physical access to a computer can get hold of the contents on the computer's disk drive by mounting it on a separate OS and change the root/admin password or restore the password database from the system's backups. For sys admins worth their salt it is not that hard.
Stuart, Glasgow,
Do not be ignorant. Their is no back doors even for the Vendors. Cisco is one of the largest security/router manufacturers in the world. If they had back doors then they would not be very secure would they?

Just keep him in prison until he gives up the codes. If he doesn't comply, he stays in for life. Fine him every penny it costs to put right.
Alastair, Alicante, Spain
Brilliant, at las a citizen bites back, the world would be a better place if more of us stood up to the ego-maniacs
Jim Jamieson, Livingston, Scotland
Shouldn't they just hire an actual (though illegal) hacker to take care of this?
Zeke, Albuquerque, USA
The real cause of this problem is the present management trend towards "reducto ad absurdam" when it comes to staffing levels - hence one man ends up with all the knowledge. I predict lots of threats followed by lots of retreats later on when truth emerges.

Hmmm... and our government wants to put all our personal details in a single database.
I don't know about you, but that idea doesn't give me any warm or comfortable feelings!
Max, London,
You would think that with all the "Smart" people in the Bay area, they could figure a way to either hack the passwords or to create new root accounts. I'm sure Cisco and the other vendors should have back doors. This should be a forgone conclusion
