"According to several informed sources, U.S. officials are discussing whether to impose economic sanctions against Russia in response to hacker attacks against organizations of the Democratic party, but has not yet come to a final decision," reports The Wall Street Journal. Journalist Damien Paletta explains: "For the imposition of sanctions will require that the White house publicly accused Russia or hackers supported by Russia, that they had hacked the computers and then leaked information that puts victims in an uncomfortable position. In the past, the US often chose not to disclose publicly who they think the perpetrators of cyber attacks".
The newspaper continues: "the FBI and American intelligence learn hacking computers of Democrats, and several officials were given to understand that he was almost certainly perpetrated by hackers affiliated with Russia. Russia categorically denies involvement, but a few firms specializing in cyber security, has also published a report that linked the hacking with the Russian hackers."
The newspaper notes that the decision on sanctions is a long process. "Even if U.S. officials concluded that hackers supported by Russia, will need to make a decision about the disclosure of that conclusion, as well as to weigh various options of response," the article says.
For example, the US administration will have to decide, is it worth it for this story to exacerbate current tensions with Russia.

"But several former US officials believe that the hacking of computers DNC - a phenomenon of a different order, since the stolen information was made public to be expected to put some people in an awkward position," - said the publication.
