Members of Anonymous recently published data from Siemens Switzerland and Fujitsu General Brazil as part of OpColtan.

"The hackers have published massive amounts of data -- including some e-mail addresses, usernames and passwords -- allegedly stolen from these Web sites," writes Softpedia's Eduard Kovacs. "Judging by the files posted on PrivatePaste, it appears that the attackers once again leveraged SQL Injection vulnerabilities to breach the sites and gain access to their databases."

In a statement accompanying the data, the hackers wrote, "Our attention turns to you, unscrupulously and greedy multinationals. Behind your famous commercial images, fabricated and marked on an false Ethic, the most cruel barbarites are hidden. Coltan, the mineral that you use to produce capacitors of mobile phones, besides being harmful to health, is also the sick result of enviromental rape and enslavement of underdeveloped populations."

"The leaked data from the Siemens attack contains basic database information as well as other non critical information related to the site. ... The leak from Fujitsu contains a short message as well as the exploitable url a few administration accounts and assistant accounts as well," Cyber War News reports. "All passwords appear to be encrypted."

The attacks follow last week's breach of the Web site for AVX Corporation, which was part of the same operation.
