Police on Tuesday called on domestic companies and institutions to strengthen their security against a ransomware variant named "Gunra," as they jointly released details of its latest attack methods with U.S. authorities.
The Korean National Police Agency (KNPA) said it has distributed a joint cybersecurity advisory regarding the Gunra ransomware with U.S. agencies, including the Federal Bureau of Investigation (FBI) and the National Security Agency.
Ransomware, a compound word of ransom and software, refers to malicious codes hackers use to encrypt or block access to data and demand money to restore access.
The advisory contains the latest attack techniques and indicators of compromise of the Gunra ransomware to help organizations defend networks from ransomware attacks, the KNPA said.
