Dear Members of Koç University,
The ransomware “WannaCry” affected hundreds of thousands of computers in 150 countries since last Friday. The ransomware attacks corporate networks more intensively using “phishing” e-mail messages and the vulnerabilities in Windows operating system.
Please read the warning below, in order to avoid the ransomware, which spreads through e-mails.
|Sample e-Mail:||Ransomware Screen:|
·The e-mail contains a Word, Excel, PDF file or a link to make the user download the ransomware.
·The ransomware which steals into the corporate network through e-mail, spreads between other computers using a vulnerability in Windows operating system.
·When executed, the ransomware encrypts all of your personal files on your computer and demands a ransom to decrypt them back. The payment does not guarantee that your files will be back. Instead, you may fall into a blackmailing trap. Security experts does not recommend to make the payment.
·The ransomware also encrypts your shared files on network.
