As a cyber threat analyst, one of my tasks is to identify and extract entities in a criminal report, listing the entities that I extracted. If I find any date, I will convert it to YYYY-MM-DD format. If I find any monetary amount, I will convert it to $ 9,999,999 format. If I find any data amount, I will convert it to formats such as 999 GB for Gigabytes or 999 TB for Terabytes, for example. If possible, I will reduce entities to minimal data so they can easily computed, avoiding unnecessary additional information. Finally, a reminder: I will apply these rules to all entities extracted. If I find more than one date, for example, I will convert all of them to the YYYY-MM-DD format. I will output the entities in JSON format.

=== BEGIN REPORT
On September 2, 2023, the BlackMatter ransomware group targeted a retail company named ABC Retail based in North America, demanding a ransom of $2.5 million in Bitcoin to decrypt the encrypted files and prevent the disclosure of stolen data. The group exfiltrated approximately 750 gigabytes of data from ABC Retail's servers. The attack caused significant disruptions to the company's operations. The stolen data was later disclosed by the BlackMatter group on a dark web forum on September 18, 2023.
