Members of the Anonymous movement claim to have breached the servers hosting customs.gov.ua, the domain used in the Ukraine by the country’s State Customs Service.
Around a year ago, the State Customs Service became part of the Ministry of Revenue and Duties, so the domain now redirects visitors to minrd.gov.ua.
The hacktivists have leaked 1 Gb of files allegedly representing proof of illicit operations involving oil and gas, and corruption schemes.
“Much of the inside of the package is related to former Ukraine Customs Chief – Ihor Kaletnyk who is an active FSB operative enforcing Russian rules of engagement in Ukraine. Also a lot of offshore money laundering by this persona and other government crooks,” the hackers noted on cyberguereilla.org next to the leaked data.
A total of 64 scanned documents have been posted on imgur.com to offer a preview into the data leak. This particular attack is part of a campaign called OpUkraine.
Many of the leaked documents are written in Ukrainian. However, a lot of the ones in English are marked as confidential.
Back in October, the same hackers claimed to have breached the systems of Ukraine's Ministry of Foreign Affairs.
