The well-known hacking group Anonymous posted a series of tweets today to warn US President-elect Donald Trump that they could expose his Russian ties.

The messages were published by Anonymous after Donald Trump took to Twitter to suggest that outgoing CIA head John Brennan might be involved in the spreading of fake news that made the headlines in the past few weeks, including “Syria, Crimea, Ukraine and the build-up of Russian nukes.”

The @YourAnonCentral Twitter handle, which has some 150,000 followers, was one of the first to reply to Donald Trump’s tweet, accusing the President-elect of being directly involved in some pretty shady activities in Russia.

“.@realDonaldTrump you have financial and personal ties with Russian mobsters, child traffickers, and money launderers,” Anonymous said in their first message.

“This isn't the 80's any longer, information doesn't vanish, it is all out there. You are going to regret the next 4 years. We could care less about Democrats attacking you @realDonaldTrump, the fact of the matter is, you are implicated in some really heavy s**t. Roy Cohen and your daddy aren't here to protect you anymore. Oh and please tell your interns not to waste money hitting us with your Moldavian bot farm, stay frosty @realDonaldTrump.”

Donald Trump tight-lipped on Anonymous’ accusations

It goes without saying that Donald Trump didn’t respond to Anonymous’ tweets, and there’s absolutely no chance he didn’t notice them since he’s such a big Twitter fan.

In other news, Donald Trump said he would keep his personal Twitter account in the next four years, so expect similar messages to be posted occasionally during his tenure at the White House.

As far as Anonymous is concerned, the hacking group hasn’t said anything about when and how it could leak the information about the new President of the United States.

They did say, however, that the next four years will be very difficult for Donald Trump, so if the hackers do have evidence regarding the new President’s involvement in shady Russian activities, expect them to go online sometime in the coming years.
