While some simple ransomware may lock the system so that it is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion. It encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem – and difficult to trace digital currencies such as paysafecard or Bitcoin and other cryptocurrencies that are used for the ransoms, making tracing and prosecuting the perpetrators difficult. Ransomware attacks are typically carried out using a Trojan virus disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. However, one high-profile example, the WannaCry worm, traveled automatically between computers without user interaction.
All about ransomware
Ever wondered what all the ransomware fuss is about? You’ve heard about it at the office or read about it in the news. Maybe you’ve got a pop-up on your computer screen right now warning of a ransomware infection. Well, if you’re curious to learn all there is to know about ransomware, you’ve come to the right place. We’ll tell you about ransomware’s different forms, how you get it, where it came from, who it targets, and what to do to protect against it.
RansomRansom A ransom is an amount of money or other assets of value that is paid for blackmail, extortion, or under other threats or coercion. The ransom is usually paid in cash or now in cryptocurrency. Online blackmail, sextortion, and ransomware all demand ransoms to avoid negative outcomes. malwareMalware Short for "malicious software," this term means computer viruses and other types of programs that cybercriminals use to disrupt or access your computer, typically with the aim of gathering sensitive files and accounts., or ransomware, is a type of malware that prevents users from accessing their system or personal files and demands a ransom payment in order to regain access. The earliest variants of ransomware were developed in the late 1980s, and payment was to be sent via snail mail. Today, ransomware authors order that payment be sent via cryptocurrency or credit card.
What Is Ransomware?
Ransomware is a type of malware threat actors use to infect computers and encrypt computer files until a ransom is paid. After the initial infection, ransomware will attempt to spread to connected systems, including shared storage drives and other accessible computers.
If the threat actor’s ransom demands are not met (i.e., if the victim does not pay the ransom), the files or encrypted data will usually remain encrypted and unavailable to the victim. Even after a ransom has been paid to unlock encrypted files, threat actors will sometimes demand additional payments, delete a victim’s data, refuse to decrypt the data, or decline to provide a working decryption key to restore the victim’s access. The Federal Government does not support paying ransomware demands.
How Does Ransomware Work?
Ransomware identifies the drives on an infected system and begins to encrypt the files within each drive. Ransomware generally adds an extension to the encrypted files, such as .aaa, .micro, .encrypted, .ttt, .xyz, .zzz, .locky, .crypt, .cryptolocker, .vault, or .petya, to show that the files have been encrypted—the file extension used is unique to the ransomware type.
Once the ransomware has completed file encryption, it creates and displays a file or files containing instructions on how the victim can pay the ransom. If the victim pays the ransom, the threat actor may provide a cryptographic key that the victim can use to unlock the files, making them accessible.
How Is Ransomware Delivered?
Ransomware is commonly delivered through phishing emails or via “drive-by downloads.” Phishing emails often appear as though they have been sent from a legitimate organization or someone known to the victim and entice the user to click on a malicious link or open a malicious attachment. A “drive-by download” is a program that is automatically downloaded from the internet without the user’s consent or often without their knowledge. It is possible the malicious code may run after download, without user interaction. After the malicious code has been run, the computer becomes infected with ransomware.
What Can You Do To Protect My Data And Networks?
Back up your computer. Perform frequent backups of your system and other important files, and verify your backups regularly. If your computer becomes infected with ransomware, you can restore your system to its previous state using your backups.
Store your backups separately. A best practice is to store your backups on a separate device that cannot be acc
