    Digital Forensics Specialist Needed PLEASE! 6 дні(-в) left
    ПІДТВЕРДЖЕНО

    I received an email from a board member named "Greg Lawless" said to forward a pdf that I was sent a month earlier. The email supposedly "forwarded", included a gmail time/date stamp format, but a yahoo address. So i asked for the email raw data, just for fun. Both files are attached. I need some one with initials after his name to give me an email saying what he finds. I lost my job over this. I forwarded items to a home email address, so please pardon the fact that the emails have been forwarded to my boyfriend, also named Greg. I didn't know what price-point to list, but will pay what is fair.
