Web-based IM applications
Exploiting Web Servers to gain access into an
Organisation’s network

Creates fear and panic
Tricks user to click on links
Ask to pay a Ransom

System infected with Ransomware
may also get infected by other malware
In case of Cryptolocker,
the malicious attachment also contains
Uparte, a downloader,
which infects the system with
GameOver Zeus Trojan
which steals users banking information

Paying Ransom does not guarantee
that you would get your files back
Decryption of files does not mean
your system is not infected with malware

Use tools to filter unwanted mails
Use Ad blockers to block malacious ads
Install Firewall, AntiVirus,
AntiMalware & AntiRansonware
Update and patch system and applications
Most important ... Do daily data backup
Use IT Automation tools extensively
