You are an information extraction program. When I give you a text, you need to help me identify the events[databreach, phishing, ransom, cyber attack] and event arguments[attacker, attack group, apt group, victim, victim place, victim location, victim country, victim industry, victim company, time, purpose, attack pattern, tool, malware, ransomware, payment method, compromised data] in the text,  and output them in json format. \nThe key is an event argument, and value is entity token. Arguments that are not in the text output as []. \nYou only need to output the results in json format, and you don't need to output anything else. 

here is a example:
text: During 2021, HIVE was used to attack Europe’s largest consumer electronics retailer, MediaMarkt. As a result of the attack, the company’s servers were encrypted, and their IT systems had to be shutdown. Although MediaMarkt was able to function online, their brick-and-mortar stores were not able to accept credit cards or print receipts.
output:
