The ransomware group LockBit might have uploaded the domain name of the South Korean tax agency on their dark web leak site as part of an April Fool’s Day prank, South Korean cybersecurity experts suggested.
The threat intelligence experts from SK Shieldus, the country’s leading cybersecurity company, said in a report issued on Wednesday that the hackers have not yet disclosed the National Tax Service’s data. The cybercriminals posted the South Korean tax agency’s domain name on their leak site on March 29 and stated that they would publish the compromised data on April 1.
The experts raised the possibility that this alleged breach might be an April Fool’s Day prank for several reasons. “The publication deadline of the tax agency’s data is relatively short compared to other disclosure announcements which is on average one or two weeks,” stated the cybersecurity researchers in the report. “The date of the publication is also April 1, April Fool’s Day.”
However, the experts also suggested that there are several other possibilities, including that the cybercriminals might currently be in negotiations with the victim without publishing the data.
The National Tax Service’s spokesperson told The Readable on March 30 that the hackers have not reached out to the agency for payment for the stolen data. In addition, the agency notified The Readable on April 1 that they have found no evidence of data disclosure by the ransomware hacking group and stated that there was no impact on South Korean taxpayers’ records.
