Hackers have attacked the Mexican state of Tabasco's website, stealing and posting details from hundreds of personal email messages online.
The hacker Darkw4rrior published the leak on Pastebin, which contains names, phone numbers, email addresses and other information taken from a total of 1,534 emails belonging to civil servants and high-profile representatives of the state.
Last week, Anonymous hackers posted emails which allegedly proved that the Mexican government is modifying a climate change bill to protect the coal mining industry from taxation.
The group targeted the Mexican Chamber of Mines (Camimex), stealing more than 700 megabytes of date which it posted online.
"You only took out our minerals, exploiting our miner brothers," read a statement on Pastebin.
In an email exchange dated 26 January, 2012, members of Camimex claim that Mexican MPs are monitoring the Climate Change Act (Ley de Cambio Climático) to ensure "it does not affect growth".
The bill, which was approved in December by an overwhelming majority in the upper house or Senate and will now be debated by the Chamber of Deputies, aims to create a domestic gas trading system that can cap and cut carbon emissions.
But federal representatives of the top northeastern mining state of Coahuila, where 95 percent of Mexico's coal reserves are located, will allegedly introduce "modifications" to the law to help mining companies within their jurisdiction.
"The intention is to avoid imposing taxes that can constitute a disadvantage to productive sectors such as coal mining," read one of the hacked email messages.
The hack is part of Operation Green Rights, which Anonymous launched last year against major oil companies, such as Exxon Mobil and ConocoPhilips.
