3. WHAT IS RANSOMWARE?
 It is a type of malware that restricts access to the
infected computer system in some way, and demands
that the user pay a ransom to the malware operators to
remove the restriction.
 This malware locked all the data in the computer and
displayed a message.
 demanding a ransom in exchange to unblock the data.

5. IMPACT OF THIS ATTACK
 WannaCry shutdown many businesses across the globe, including
the European manufacturing plants of automotive giants Nissan
 $17,000 Amount paid by the Hollywood Presbyterian Medical
Center in 2016 to unlock files and return to business as usual.
 209 million Amount paid in 2016 to cyber-criminals using
ransomware

6.  On 12 May 2017, a massive ransomware attack
occurred across a wide range of sectors, including
health care, government, telecommunications and
gas.
 WannaCry has spread to over 300,000 systems in
over 150 countries

7. Some Facts About Ransomware
 TYPICAL RANSOMWARE SOFTWARE USES RSA
2048 ENCRYPTION TO ENCRYPT FILES.
AN AVERAGE DESKTOP COMPUTER IS
ESTIMATED TO TAKE AROUND 6.4
QUADRILLION YEARS TO CRACK AN RSA 2048
KEY.

8. BITCOINS
Bitcoins are a form of cryptocurrency, meaning
they do not have a physical representation.
they are stored in anonymous digital wallets.
They can be transferred anywhere in the world via
the Internet. They can be paid from anywhere, to
anywhere with total anonymity.

9. TOR (ANONYMITY NETWORK)
 TOR, which stands for “The Onion Router” is a network
and browser developed to enhance and anonymize
Internet traffic.
 All traffic is encrypted .
 developed by the U.S. Naval Research Laboratory and
Defense Advanced Research Projects Agency (DARPA).

10. IF YOU'RE A VICTIM, SHOULD YOU
PAY THE RANSOM?
 Never pay Ransom.
 The best option is to restore the data from backup.
 try decrypting the files using recovery tools.
 Work with data recovery experts who can reverse engineer
malware and help gain access to your data.

11. RANSOMWARE INFECTION
 Opens an infected email attachment
 Clicks on an infected link
 Installs an infected app – from a third-party app store
 Visits a legitimate website that has been infected

12. HOW TO PROTECT YOURSELF?
 Update your Windows software to the latest edition.
 Backing up data is key! Make a copy and secure it.
 Scan your systems for viruses and malwares using the latest
anti-virus software in the market.
 To protect against WannaCry, apply the latest Microsoft
security patches.

13.  Backup all your data and store it in a secure
location.
 Scan all outgoing and incoming emails with
attachments.
 Update anti-virus software and conduct regular
scans.
 Spread awareness among employees to identify
scams, malicious links and emails.
 Segment the company network

14. CONCLUSION
 Ransomware is a type of malicious
software from cryptovirology that threatens to publish the
victim's data or perpetually block access to it unless a ransom is
paid
 more advanced malware uses a technique called cryptoviral
extortion, in which it encrypts the victim's files, making them
inaccessible, and demands a ransom payment to decrypt them.
