Last month, the ransomware group that attacked SGI Seoul Guarantee, which experienced a computer system failure due to hacking, claimed to have leaked 13.2 terabytes (TB) of internal data.
According to the security industry on the 5th, the security corporation Hackmanac, which operates mainly in the United Arab Emirates (UAE), explained in an X post that the "Gunra" hacking group claims responsibility for the SGI cyber attack and asserts that it possesses 13.2 TB of Oracle databases.
Gunra is a ransomware suspected to have been used in the recent SGI Seoul Guarantee hacking attack. The post cited by Hackmanac is registered on the dark web address operated by this organization.
SGI Seoul Guarantee restored its core computer system on the 17th of last month, just three days after the ransomware attack caused a system failure. SGI Seoul Guarantee determined that the cause of the failure was the ransomware attack and normalized its operations using its own backup data.
At that time, SGI Seoul Guarantee stated that there had been no contact from the hacker regarding any monetary demands for the stolen information.
