EXCLUSIVE: NY Post’s ‘Smoking Gun’ Hunter Biden Email 100% Authentic, Forensic Analysis Concludes
An email Hunter Biden received in April 2015 from a Burisma executive discussing an introduction to then-Vice President Joe Biden, which lies at the heart of a New York Post investigation, is unquestionably authentic, a cybersecurity expert told the Daily Caller News Foundation on Thursday.
The DCNF obtained a full copy of Hunter Biden’s alleged laptop from former New York Mayor Rudy Giuliani on Wednesday. The DCNF provided Robert Graham, the founder of the cybersecurity firm Errata Security, with a copy of the email and its metadata for forensic analysis.
Graham, who has been cited as a cybersecurity expert in The Washington Post, the Associated Press, Wired, Engadget and other news and technology outlets, told the DCNF that he used a cryptographic signature found in the email’s metadata to validate that Vadym Pozharsky, an advisor to Burisma’s board of directors, emailed Hunter Biden on April 17, 2015.
EXCLUSIVE: Right wing morons don't understand what DKIM is
The purpose of a DKIM signature is to verify the email came from an email address at a specific domain, to combat spoofed emails. It does NOT prove the content of the email was unaltered or authentic. That’s a different kind of signature, and calling DKIM a “cryptographic” signature seems like a purposeful attempt to conflate the two.
"It means an email of exactly the text above (it cannot be altered) was sent by Pozharskyi to Hunter Biden on Friday the 17th of April , 2015."
No it doesn't.
The DKIM signature verifies that the date field wasn't modified after being sent. However when you send an email you can set the Date field to anything you'd like, DKIM will not validate that it is the correct date.
So we can say that we verified the email was sent between 2012 and 2016 but not the exact date.
"It appears that Hunter introduced Joe to energy executives in the Ukraine while being paid by these executives when Joe Biden was Vice President of the United States."
Appearances can be deceiving. A single email without further context isn't enough evidence to prove anything illegal took place. It would certainly be great if they released the metadata for the rest of the emails.
