Optus Under $1 Million Extortion Threat in Data Breach

Jeremy Kirk has done a terrific job of investigating and reporting on what we know so far about the Optus data leak and extortion attempt. He reports:

Early Saturday, a person going by the nickname “Optusdata” published two samples of the purported stolen data on a well-known data leak forum. The attacker writes that Optus can prevent the sale of the data to other cybercriminals if it pays $1 million in the monero cryptocurrency.

[…]

The two released data samples contain around 100 records and include data fields such as name, email address, physical address, passport number, driver’s license number, birth date, whether a person owns their home or not and more. The data covers current and former Optus customers.
