I just finished posting a couple of articles on ransomware.
This is the first one in the series- https://medium.com/@9dbfde4e00b1/f4da40a93d40
while the last article written 3 days ago is here — https://medium.com/@9dbfde4e00b1/b4a47e905382.
I intend to make a small PDF book available on request.
Also thinking of a series on Phishing/Spear Phishing, threats experienced by millions every day but mostly downgraded by Users.
