The top U.S. spy agency is going public with concerns about the latest document dump Attack.Databreach by the online whistle-blower organization WikiLeaks , warning that all Americans should be `` deeply concerned '' about the potential fallout . A spokesman for the U.S. Central Intelligence Agency refused to comment Wednesday on the authenticity of the 8,771 documents , but argued there could be little doubt about WikiLeaks ' intentions `` to damage the Intelligence Community 's ability to protect America against terrorists and other adversaries . '' `` Such disclosures not only jeopardize U.S. personnel and operations , but also equip our adversaries with tools and information to do us harm , '' CIA spokesman Jonathan Liu said in a statement . White House press secretary Sean Spicer also expressed alarm Wednesday , telling reporters the U.S. `` will go after people who leak Attack.Databreach classified information . '' `` This is the kind of disclosure that undermines our security , our country and our well-being , '' he told reporters , adding President Donald Trump is `` extremely concerned . '' Review of documents Like the CIA , Spicer refused to confirm the authenticity of the WikiLeaks documents . But several cybersecurity experts and former intelligence officials who reviewed them told VOA that they appeared to be real . WikiLeaks said it obtained Attack.Databreach the documents from a former U.S. government hacker . And a U.S. intelligence official told VOA , on condition of anonymity , that it appeared a CIA contractor might have been the source . `` There 's always someone with the permissions to do this sort of thing , '' said Alex McGeorge , the head of Threat Intelligence at Immunity Inc. , a cyber firm that does some work with government agencies . McGeorge also said that while the disclosures were damaging , WikiLeaks ' claim that the documents dump Attack.Databreach represented the CIA 's `` entire hacking capacity '' was most likely overblown . `` What we currently have in this dump does n't provide a whole lot , '' he said . Many of the WikiLeaks documents appeared to be online transcripts of conversations between intelligence agency employees working to exploit software to turn digital devices — such as mobile phones like Apple or Android smartphones , or even Samsung 's smart televisions — into listening devices . Limiting damage But at least for now , WikiLeaks appears to be limiting the damage . `` They did n't disclose the code , at least , and populate the marketplace with what we would consider cyberweapons left on the battlefield that can be reverse-engineered and used against us , '' said Jeff Bardin , CIO of the cybersecurity firm Treadstone 71 and a former member of U.S. Air Force intelligence . In its statement Tuesday , WikiLeaks said it was only holding off on releasing the critical codes `` until a consensus emerges on the technical and political nature of the CIA 's program and how such weapons should be analyzed , disarmed and published . '' Even more worrisome for some current and former U.S. and Western officials , though , is the possibility of Russian involvement . `` I 'm now pretty close to the position that WikiLeaks is acting as an arm , as an agent of the Russian Federation , '' former CIA Director Michael Hayden , a retired Air Force general , told CNN Wednesday . Other former officials noted Russia was on the short list of countries capable of foiling the CIA 's cyber efforts . `` It is in Russia 's interest to see the CIA discredited , '' former British cybersecurity official Jonathan Shaw said Tuesday , following the WikiLeaks disclosure . A January report by the U.S. intelligence community also concluded with `` high confidence '' there was an ongoing relationship between Russian intelligence and WikiLeaks
