(Sent to Deerwood Technology’s GUARDIAN Network Support®clients on Saturday, May 13th.)
Yesterday, a massive cyberattack spread globally in a only a matter of minutes.
The initial attack was via email, through spam. These messages are typically fake invoices, job offers and other lures which are sent to random email addresses. Within the email is a .zip file and once clicked, that initiates the WannaCry infection.
The attack is then spread on internal networks with a worm which abuses SMB, a network file sharing protocol. Other aspects of the malware leverage file-less exploitation techniques, and the malware is morphing rapidly in the wild with over a dozen variants seen thus far.
