A hacker has posted private email messages and photos of former US presidents George Bush Snr and George W Bush.
According to a report from The Smoking Gun, the hacker was able to breach Bush family email accounts, and obtain personal correspondence, including photos and personal information from both presidents.
While neither former president had his personal account breached, the hacker is believed to have obtained correspondence from family members discussing the health of the elder Bush and speculation on funeral arrangements in the midst of a 2012 health scare.
The hacker, who identified himself with the alias "Guccifer" also posted photos of self-portrait paintings from George W Bush. Guccifer said in the report that he believes the US Secret Service is investigating the incident.
Michael Sutton, vice president of research at Zscaler, said that despite initial security terms, the attack does no appear to be a serious threat.
"The fact that the attacker was all too willing to make the email contents public suggests that the attack was done for the challenge, as opposed to something more nefarious," Sutton explained.
"The attacker did however clearly target the Bush family directly, having compromised accounts from multiple family members and friends."
The incident is not the first time in which a US politician has suffered a breach at the hands of hackers. In 2008 a university student accessed the email account of then-vice presidential candidate Sarah Palin. The student was later indicted on criminal charges.
