Charges against a Sydney teenager accused of using information from last month's Optus data breach in a blackmail scam will be reviewed, after his lawyer told a court he would plead guilty.
Australian Federal Police (AFP) charged Dennis Su with two offences earlier this month, claiming he sent text messages to 93 Optus customers demanding they transfer $2,000 to a bank account.
The 19-year-old allegedly threatened to use their information for financial crimes if they didn't comply, according to police, but nobody paid the money.
The charges were laid after a bank account belonging to a juvenile, which Mr Su allegedly used, was identified.
Mr Su appeared at Sydney's Downing Centre Local Court on Thursday morning, where his lawyer said he was ready to plead guilty to his existing charges.
But Hannah Panizzutti, who appeared for the Commonwealth Director of Public Prosecutions, requested an adjournment until November 8 "to review the charges and ensure he has been charged correctly".
"I understand it would be ready to proceed to sentence on that day," she told the court.
Mr Su's lawyer said in light of the possible changes he would defer entering a plea.
Magistrate Robert Williams noted it was the first time the case had come before court.
"I'll allow them some opportunity to properly consider the charges," he said.
AFP officers seized a mobile phone they allege was linked to the text message from a home in Rockdale.
Mr Su was initially charged with using a telecommunication network with the intent to commit a serious offence and dealing with identification information.
The AFP said those charges carry a maximum penalty of 10 and seven years' imprisonment respectively.
They said Mr Su was not suspected of being responsible for the Optus hack but allegedly attempted to benefit financially from the thousands of stolen records that were dumped online.
The case returns to court on November 8.
