No charges were brought against Clinton over the server scandal

Hillary's Clinton's server has been the target of hackers in Russia and China at least four times, a new report claims.

Computers in China tried to break into Clinton's private server three times in 2014 — while a computer in Russia attempted to gain access once in 2013, the New York Post reported.

'They were extremely careless in their handling of very sensitive, highly classified information,' FBI authorities said in July.

FBI officials highlighted that there were a number of hacking attempts both while Clinton was secretary of state and afterward.

In 2015, the company in charge of Clinton's servers, Platte River Networks, tightened up on security, The Post reported.

'I spent some time in their firewall just now locking everything down,' said Bill Thornton, an IT consultant at Platte River, according to the newspaper.

The company didn't conduct what is called 'penetration testing,' or asking a hacker to try to break into your server to see if it is protected enough.

Executives at Platte River are also believed to have tried to distance themselves from Clinton as it came to light that she had been using a private email server to conduct official government business, The Post reported.

In one message, IT executives called their work — purging Clinton emails — to be 'Hillary's cover-up operation.'

Platte River used to retain emails for Clinton for 60 days, the FBI said in its report.

Now the company can only purge emails after 30 days, The Post reported.

The company and its executives have been subpoenaed by Congress to testify about Clinton's server probe.

Both Bill Thornton and colleague Paul Combetta refused to answer questions last week.
