Victims are often given instructions on how to make the payment, typically through cryptocurrencies like Bitcoin, which adds an additional layer of anonymization for the attackers.
Locker Ransomware
Locker ransomware takes a slightly different approach compared to crypto ransomware. Instead of encrypting files, locker ransomware locks the victim out of their system entirely. This can prevent users from accessing their computers, applications, or files until they pay the ransom. Locker ransomware can be particularly frustrating, as it denies the victim access to their entire system, making it impossible to continue working or even access important data.
Ransomware as a Service (RaaS)
Ransomware as a Service (RaaS) is a disturbing trend in the cybercriminal underworld. It allows individuals without technical expertise to launch ransomware attacks by renting or purchasing pre-packaged ransomware kits. RaaS empowers non-technical criminals to enter the ransomware business, thereby amplifying the impact and reach of this malicious software.
Leakware
Leakware, also known as doxware, is a type of ransomware designed to exploit the fear of data exposure. Instead of encrypting files, leakware threatens to publicize sensitive information unless the ransom is paid. The attackers may threaten to make personal or confidential data public, potentially damaging an individual’s or organization’s reputation and privacy.
Scareware
Scareware is a form of ransomware that preys on fear and deception. It typically presents itself as legitimate security software or a warning message, tricking users into believing their system is infected with viruses or malware. Scareware uses fear tactics to coerce victims into paying a ransom to fix the non-existent problems, exploiting their concerns about their computer’s security.

What is Crypto Malware?
Crypto malware is a type of ransomware that poses a significant threat to data security. It employs strong encryption algorithms to encrypt all the data on an infected computer, rendering it inaccessible to its rightful owner. As a result, victims are unable to access their files or documents, causing severe disruption to their personal or professional lives.
Crypto malware perpetrators often demand payment in bitcoin, a digital currency known for its anonymity and lack of traceability. The use of bitcoin allows cybercriminals to receive ransom payments without revealing their identities, making it a preferred method for extorting victims.
If a victim chooses to pay the ransom, they are provided with instructions on how to submit the payment and obtain the decryption key. This key is essential for unlocking the encrypted data and restoring access to the compromised files or systems.
It is crucial to note that having effective backup systems in place can greatly mitigate the impact of crypto malware. Regularly backing up data to secure offline or offsite locations ensures that even if data is encrypted by crypto malware, it can still be restored from a secure backup source. This eliminates the need to pay the ransom and reduces the potential financial losses.
Differences Between Ransomware and Crypto Malware
The main difference between ransomware and crypto malware lies in their approach to data encryption and payment.
Ransomware typically targets critical files and systems, encrypting them and demanding payment for access. It selectively encrypts specific files or folders, leaving the rest of the data intact. The victim is then required to pay a ransom, usually in the form of cryptocurrency, in exchange for the decryption key that unlocks the encrypted files.
Crypto malware takes a more aggressive approach by encrypting all data on a computer or network, leaving no files untouched. This broader scope of encryption ensures that the victim’s entire system is held hostage until the ransom is paid. The cybercriminals behind crypto malware demand payment in exchange for the decryption key necessary to unlock the encrypted data.
Understanding these differences is crucial in identifying and responding to these malware attacks. Whether it is ransomware or crypto malware, the end goal is the same – to extort money from victims by encrypting their data and demanding payment for its release.
| Ransomware | Crypto Malware |
|---|---|
| Selectively encrypts specific files or folders | Encrypts all data on a computer or network |
| Demands payment for access to encrypted files | Demands payment for the decryption key |
| Targets critical files and systems | Encrypts all data, leaving no files untouched |
