Miss Teen USA hacker pleads guilty to 'sextortion' threats
A US teenager has pleaded guilty to hacking into the computers of young women, using their webcams to take photos, and then threatening the victims with blackmail.
Prosecutors had accused Jared James Abrahams of carrying out the attacks over a two-year period.
The current winner of the Miss Teen USA beauty pageant - Cassidy Wolf - had been identified as one of his targets.
The 19-year-old computer science student will be sentenced in March.
He faces up to 11 years in jail and $1m (£626,000) in fines.Photo threats
According to prosecutors, at least two dozen women in the US, Ireland and elsewhere had their PCs hacked by Abrahams.
WEBCAM SAFETY TIPS
- Webcams can be affected by viruses so be wary of emails and social network messages from strangers
- Make sure anti-virus and firewall protection is kept up to date
- Avoid putting webcams in bedrooms or other private areas
- Unplug the webcam, cover the lens or point it at a blank wall when it is not in use
- Be sure you can trust the person you are chatting to and remember webcam footage can be recorded and potentially shared online
- If you have been the victim of inappropriate sexual contact via webcam tell a trusted adult and report it to the police via the Child Exploitation and Online Protection centre (Ceop)

Court records state that the computer science student told the women - who ranged from the age of 16 to their early 20s - that he had taken pictures of them while they were undressed. He then threatened to post the images to social media sites unless they sent additional photos or stripped via a Skype video feed.
The authorities said at least two of the victims had complied.
Cassidy Wolf - a schoolmate of Abrahams - did not respond to his threats.
Abrahams later posted a naked photo of the beauty queen online and is reported to have sent her a message saying: "Your dream of being a model will be transformed into a porn star."
Appearing in court at Santa Ana, California, he pleaded guilty to three counts of extortion and one count of unauthorised computer access.
He also told the judge that he had autism - a factor his lawyer said should be taken into account when sentencing takes place.Webcam warnings
The case is not the first of its kind.
In July another American, Karen "Gary" Kazaryan, pleaded guilty to hacking into women's computers, stealing their online identities and then using them to fool other women into removing their clothing on camera.
The previous year the US courts convicted Trevor Timothy Harwell for installing spyware on women's laptops and then sent an alert stating that they needed to place the machines "near hot steam" to fix an internal sensor. Many of the women took the machines to their bathrooms to do so, where he took photos of them getting undressed.
The charity, Childnet International, has become so concerned by such threats that in June it suggested webcams should be disconnected when not in use.
Cassidy Wolf posted a similar message in a tweet after Abrahams pleaded guilty: "Happy to know that this nightmare is coming to an end #ProtectYourselves #CoverYourWebcams."
