Understand Ransomware And It’s Working 

What Is Ransomware? 

Ransomware is malicious software that threatens to block and publish access to files or a computer system. It encrypts the data or system till the user pays money to the virus attacker. Most of the time, the demand for ransom comes with a particular deadline, and if users don’t pay on time, the ransom increases, and they experience data loss.

Well, Ransomware attacks by hackers are increasing day by day. So, when you experience the same, don’t forget to stick to a Ransomware recovery services provider. Hackers can attack any business or consumer from all industries.

Even there are many agencies, like the FBI, that are working on Ransomware protection. For further information, you need to know that half of the victims that pay for ransom suffer from repeated Ransomware attacks.

How Ransomware Works? 

The common way attackers impact an organization is by just sending mail with attachments or malicious links. When an employee clicks on it and opens that, then it initiates a virus attack. Daily, millions of emails are sent and received to or by people, but malicious links are shared to the targeted person or organization only.

The Ransomware attack process starts when any device is exposed to malicious code. Well, it includes 7 stages of the attack.

First: Infection

Ransomware gets downloaded and installed by the user on their system.

Second: Execution

In this stage, the Ransomware scans and finds the locations for targeted data consisting of stored files, mapped or unmapped network-accessible systems. There are many Ransomware attacks that delete or encrypt a file or folder.

Third: Encryption

It performs a key exchange by Control and Command Server, using the encryption option for scrambling all data explored at the Execution step. Also, it locks data access in a system.

Fourth: User Notification

It adds some instruction files with details on the pay-for-decryption. Later those files show as a note to the user.

Fifth: Cleanup

Generally, Ransomware deletes or terminates by itself and leaves the payment instruction files only.

Sixth: Payment

When the user clicks on the payment instructions link, it takes the victim to a website page with details. It includes information on how to make the ransom payment required.

Generally, hidden TOR services are used to obfuscate and encapsulate these communications to avoid detection by monitoring network traffic.

Seventh: Decryption

Once victims pay the amount through the Bitcoin address of the attacker, they might get a decryption key. But, there will be no guarantee that the decryption key will be delivered to you as said. So, in this situation, the Ransomware recovery services provider helps the most.
