Hackers have broken in to the e-mail of the US Republican vice-presidential candidate, Alaska Governor Sarah Palin. The hackers, who targeted a personal Yahoo account, posted several messages and family photos from her inbox. The campaign of running mate John McCain condemned their action as "a shocking invasion of the governor's privacy and a violation of the law".  The hacking comes amid questions about whether Palin used personal e-mail to conduct state business. According to law, all e-mails relating to the official business of government must be archived and not destroyed. However, personal e-mails can be deleted. Palin is currently under investigation in Alaska for alleged abuse of power while governor. A group called Anonymous has claimed responsibility for the hacking of Palin's e-mail. It posted five screenshots, two digital photos of Palin's family and an address book to the whistle-blowing Wikileaks website. The information was taken from Palin's gov.palin@yahoo.com e-mail account. One message exposed is apparently an exchange between Palin and the deputy governor of Alaska, Sean Parnell, who is seeking election to Congress. Another is between Palin and friend Amy McCorkell, in which the latter says she is praying for the governor and adds, "Don't let the negative press get you down" The family photographs of the Palins posted on Wikileaks are thought not previously to have been in the public domain. "The matter has been turned over the appropriate authorities and we hope that anyone in possession of these e-mails will destroy them," the McCain campaign said in a statement. Subsequent investigation has shown that the gov.palin@yahoo.com account has been shut down along with another, gov.sarah@yahoo.com, also owned by Palin. It is not clear yet what methods the hacking group used to access to the e-mail account. The screenshots posted by the hackers reveal that they carried out the attack via a so-called proxy service to hide their tracks and limit the chance that they would be traced. BBC
