What do you need to know about ransomware?
Many companies need to put together a specific plan for ransomware, known as a “ransomware playbook.” We think even small firms should spend some time planning what they will do if they’re hit. When ransomware hits, time is of the essence. You’re literally in a race against time, and ransomware moves at computer speed.
When do you need a ransomware Playbook?
Ransomware is hitting companies of all sizes, sometimes with disastrous results. Many companies need to put together a specific plan for ransomware, known as a “ransomware playbook.” We think even small firms should spend some time planning what they will do if they’re hit. When ransomware hits, time is of the essence.
How much money do you need to pay for ransom?
Users are told that unless a ransom is paid, access will not be restored. The ransom demanded from individuals varies greatly but is frequently $200–$400 dollars and must be paid in virtual currency, such as Bitcoin.
How is drive by downloading ransomware spread?
Drive-by downloading occurs when a user unknowingly visits an infected website and then malware is downloaded and installed without the user’s knowledge. Crypto ransomware, a malware variant that encrypts files, is spread through similar methods and has also been spread through social media, such as Web-based instant messaging applications.
Ransomware is a type of malware threat actors use to infect computers and encrypt computer files until a ransom is paid. (See Protecting Against Malicious Code for more information on malware.)
How does ransomware encrypt files on a computer?
Most of the current ransomware variants encrypt files on the infected system/network (crypto ransomware), although a few variants are known to erase files or block access to the system using other methods (locker ransomware).
How can I protect my computer from ransomware?
Store your backups separately. Best practice is to store your backups on a separate device that cannot be accessed from a network, such as on an external hard drive. Once the backup is completed, make sure to disconnect the external hard drive, or separate device from the network or computer.
How is ransomware an opportunistic cyber threat?
While almost all ransomware infections are opportunistic, disseminated through indiscriminate infection vectors such as those discussed above, in a few very rare instances cyber threat actors specifically target a victim. This may occur after the actors realize that a sensitive entity has been infected or because of specific infection attempts.
