Ransomware Is Malware That Employs Encryption To Hold A Victim’s Information At Ransom. A User Or Organization’s Critical Data Is Encrypted So That They Cannot Access Files, Databases, Or Applications. A Ransom Is Then Demanded To Provide Access.

Ransomware May Distribute Through Trojan Virus As Well As The Phishing E-mail. This Is Common Process Adopted By The Ransomware Developer. One Thing Is Better For Ransomware Is That Ransomware Doesn't Appear On Its Own.

There Are Number Of Path To Disperse Ransomware On The Internet Or Network, Which Is Described Underneath:

  • Trojan Virus
  • Phishing Emails
  • RDP (Remote Desktop Protocol)
  • Drive By Downloads From A Compromised Website Or Web Links
  • USB And Removal Media
  • Freeware Apps
  • Free Software
  • Spam Mails

Ransomware Attacks And Their Variants Are Rapidly Evolving To Counter Preventive Technologies For Several Reasons:

  • Easy Availability Of Malware Kits That Can Be Used To Create New Malware Samples On Demand.
  • Use Of Known Good Generic Interpreters To Create Cross-platform Ransomware (for Example, Ransom32 Uses Node.js With A JavaScript Payload).
  • Use Of New Techniques, Such As Encrypting The Complete Disk Instead Of Selected Files.

Today’s Thieves Don’t Even Have To Be Tech Savvy. Ransomware Marketplaces Have Sprouted Up Online, Offering Malware Strains For Any Would-be Cybercrook And Generating Extra Profit For The Malware Authors, Who Often Ask For A Cut In The Ransom Proceeds.

How Does Ransomware Works?

Ransomware Works Very Intelligently To Target The Internet User. Ransomware Utilizes The Spam Mail, Phishing Email To Allure The User Of The Internet. However, Ransomware May Also Use Social Engineering To Distribute Code, Which May Work To Reconfigure The Computer System File Step By Step. Even Though Ransomware Is A Considered As A More Advanced Malware Program. Ransomware Can Create A Vulnerable Condition Inside The Machine.

Ransomware Uses Asymmetric Encryption. This Is Cryptography That Uses A Pair Of Keys To Encrypt And Decrypt A File. The Public-private Pair Of Keys Is Uniquely Generated By The Attacker For The Victim, With The Private Key To Decrypt The Files Stored On The Attacker’s Server. The Attacker Makes The Private Key Available To The Victim Only After The Ransom Is Paid, Though As Seen In Recent Ransomware Campaigns, That Is Not Always The Case. Without Access To The Private Key, It Is Nearly Impossible To Decrypt The Files That Are Being Held For Ransom.

Many Variations Of Ransomware Exist. Often Ransomware (and Other Malware) Is Distributed Using Email Spam Campaigns Or Through Targeted Attacks. Malware Needs An Attack Vector To Establish Its Presence On An Endpoint. After Presence Is Established, Malware Stays On The System Until Its Task Is Accomplished.

After A Successful Exploit, Ransomware Drops And Executes A Malicious Binary On The Infected System. This Binary Then Searches And Encrypts Valuable Files, Such As Microsoft Word Documents, Images, Databases, And So On. The Ransomware May Also Exploit System And Network Vulnerabilities To Spread To Other Systems And Possibly Across Entire Organizations.

Once Files Are Encrypted, Ransomware Prompts The User For A Ransom To Be Paid Within 24 To 48 Hours To Decrypt The Files, Or They Will Be Lost Forever. If A Data Backup Is Unavailable Or Those Backups Were Themselves Encrypted, The Victim Is Faced With Paying The Ransom To Recover Personal Files.
