“After news broke that the Democratic National Committee had been hacked, a group of prominent computer scientists went on alert. The group of individuals, led by a Hillary supporter, started snooping around the Trump Tower computers to allegedly see if these servers had also been hacked.
This group was led by Indiana University professor, Jean Camp. Professor Camp, according to Circa, was a staunch Hillary supporter:
(…) Some techies uncovered that the the Trump Tower servers began to be bombarded with the same exact invalid look-up requests that use the words “trump” and “alfa” together, which were automatically placed in the servers’ log file by the server. According to the New York Times, computer logs showed that two servers at Alfa Bank sent more than 2,700 “look-up” messages to the Trump servers.
At about the same time, the FBI received a complaint from “cyberexperts” about a possible Trump-Alfa Bank connection, which led the FBI to investigate into a Trump-Alfa Bank connection. According to the New York Times:
In classified sessions in August and September of 2016, intelligence officials also briefed congressional leaders on the possibility of financial ties between Russians and people connected to Mr. Trump. They focused particular attention on what cyber experts said appeared to be a mysterious computer back channel between the Trump Organization and the Alfa Bank, which is one of Russia’s biggest banks and whose owners have longstanding ties to Mr. Putin.
At about the same time that the FBI began its investigation, Christopher Steele began pushing the now debunked claim that Trump was connected to Alfa Bank. In mid-September Steele submitted his memos, and at least one of these included the Trump-Alfa Bank connection. Steele submitted these memos to the press and to the FBI.
We know that the FBI received a copy because at this time the FBI sought and received a FISA warrant related to Russia-linked bank, using the Steele dossier as evidence. This is the only plausible piece of evidence that the FBI could have used. Before this time, the FBI was turned down by the FISA court but on this occasion, a warrant was granted. (As McCabe said: The FISA warrants would not have been granted without the Steele dossier.)
The FBI had no other evidence on the Trump – Russia bank connection and as time went by they had no additional evidence. The New York Times then reported:
Law enforcement officials say that none of the investigations so far have found any conclusive or direct link between Mr. Trump and the Russian government. And even the hacking into Democratic emails, F.B.I. and intelligence officials now believe, was aimed at disrupting the presidential election rather than electing Mr. Trump.”
