Christian Whiton, a former aide to President Trump has accused the Biden administration of not doing enough to counter aggressive hacking by Chinese cybercriminals. It comes after the Chinese hackers targeted the Microsoft Exchange servers last year in a massive cyber operation. Speaking to Fox News, Mr Whiton questioned the resolve of President Joe Biden to crack down on Chinese actions pointing to the much tougher action taken against Russia over similar hacks.

       Mr Whiton was asked on Fox Business whether the Biden administration was doing enough to deal with aggression from China.

       He replied: "No they are not, you know this is a pretty good start in that it is not just the United States.

       "But also NATO, the EU and are so-called Five Eyes intelligence-sharing partners that is countries like Canada, Australia, New Zealand, the UK and the US calling out China for what it did.

       "Everyone in the cyber industry has sort of known that the Microsoft exchange server attack last year was perpetrated from China.

       "Very sophisticated attack incidentally much more so than the ransomware attacks that have made news on Colonial pipelines for example.

       "But it is funny President Biden actually at least threatened the Russians, he twice threatened Vladimir Putin that we would retaliate for Russian cyberattacks.

       "He hasn't followed through on either of those things.

       "But I notice with China there is no related threat of any sort of retaliation."

       White House press secretary Jen Psaki has pushed back against claims Biden has been inconsistent in his response towards China and Russia.

       Ms Psaki said: "We are not allowing any circumstance or consideration to prevent us from taking actions where warrant.

       "And also we reserve the option to take additional actions were warrant as well.

       "This is not the conclusion of our efforts as it relates to cyber activities with China or Russia."
