Victorian man sentenced for telephone attacks and phishing scams

A 30-year-old Bendigo man today (11 November 2021) has been sentenced in the Melbourne County Court to 307 days, already served, released on a recognizance release order for telephone based offending, various hacking and financial phishing offences to facilitate large scale fraudulent purchases.

He was also given a community corrections order for a period of 3 years and 300 hours of community service was imposed. Between 14 October and 18 October 2018, multiple Victoria Police Stations were affected by a coordinated denial of service attack on their phone system.

The attack involved individual Police Stations being inundated with incoming telephone calls, overwhelming the system and preventing members of the police station from making phone calls and/or receiving legitimate phone calls from members of the public or government personnel. About 10,984 telephone calls were diverted to Victoria Police stations by the Bendigo man.

Further telephone based offending was identified as part of the investigation in which the man had devised a computer system which enticed people to respond to a text message requesting a call back immediately as they needed help.

As part of the cyber-attack, the system played pre-recorded abuse and threats to people replying to the call.

The victim and other unsuspecting people responding to the text were bridged together and further pre-recorded abusive messages were played causing members of the public to abuse and threaten one another in a case of mistaken identity.

Between November 2017 and June 2019, the man also conducted various hacking and financial phishing offences to facilitate large scale fraudulent purchases.

The police investigation further revealed the man used a series of pseudonyms to mask his offending, by falsely subscribing mobile telephone services, email address, and using drop addresses to collect and distribute fraudulently purchased items. The man obtained 2500 credentials including names and credit card details.

The man was arrested by the AFP on 14 June 2019 at his home in Bendigo and was later charged with:

One count of causing an unauthorised impairment of electronic communication to or from a computer knowing that the impairment was unauthorised contrary to subsection 477.3(1) of the Criminal Code Act 1995(Cth). Unauthorised impairment of electronic communication.

One count of using a carriage service in such a way that reasonable persons would regard that use as being menacing, harassing or offensive, contrary to subsection 464.17(1) of the Criminal Code Act 1995 (Cth).
