For those of you that follow the news, you have heard of the massive cyber attack of ransomware worldwide over the weekend. So far this ransomware has a global scope hitting at least 150 countries with hundreds of organizations hit and over 200,000 victims. Security experts fear the outbreak will increase today after employees return to their jobs and access their computers on Monday. Some companies have gone so far as to instructed employees not to login until all their systems have been patched.
Security professionals have warned the public that ransomware was on the rise and to take precautions however the widespread scope of this attack exceeded expectations.
