How I fooled Microsofts Safe Link technology in 5 minutes

The Safe Link technology was recently launched by Microsoft through Office 365. The goal of this technology is to rewrite all URL's in email to a URL classification service, so at the time of user-clicks it's possible to reclassify a URL. This method is preferred as spammers more often replace the phishing URL's site content after a message is being scanned, hence there is a need of reclassification later. Safe link is Microsoft's "best-effort" to do so.
