Scareware: Scareware is a tactic that uses popups to convince victims they have a virus and directs them to download fake software to fix the issue Example Ransomware Variants VariantĬryptoLocker ransomware was revolutionary in both the number of systems it impacted and its use of strong cryptographic algorithms. A lock screen displays the ransom demand, possibly with a countdown clock to increase urgency and drive victims to act. Screen Lockers: Lockers completely lock you out of your computer or system, so your files and applications are inaccessible.

In order to get the decryption key, the victim must follow the instructions left on a ransom note that outline how to pay the attacker – usually in Bitcoin. Ransom Demand: Once the data has been encrypted, a decryption key is required to unlock the files. Depending on the variant, the malicious software may find opportunities to spread to other devices and systems across the organization.

Encryption: After a device or system has been infected, ransomware then searches for and encrypts valuable files. In most cases, the victim ends up clicking a malicious link in the email, introducing the ransomware variant on their device. Infection: Ransomware operators often using phishing emails and social engineering techniques to infect their victim’s computer. According to CrowdStrike’s annual Global Security Attitude Survey, the average ransom payment is $1.79 million. Ransomware remains one of the most profitable tactics for cybercriminals. If the ransom payment is not made, the threat actor publishes the data on data leak sites (DLS) or blocks access to the files in perpetuity. If the payment is made, the victim receives a decryption key to restore access to their files. Ransomware is a type of malware that encrypts a victim’s data until a payment is made to the attacker.
