Ransomware is a type of malicious software, or malware, designed to deny access to a computer system or data until a ransom is paid.
Typically, ransomware is spread through phishing emails or because you have unknowingly visited an infected website.

In HelpRansomware you will find a valuable source of information, a unique customer-centric guide with best practices and advice to not only remove ransomware but also to prevent, protect and respond to a ransomware attack.
What is a Ransomware?
What is a Ransomware? Simply: it’s a form of malware designed to encrypt files on a device, rendering all systems that rely on them unusable.
In exchange for the decryption key, the hackers demand a ransom from the victim of the attack.
In recent years, ransomware attacks have become increasingly widespread among government entities, both state and local, and critical infrastructure organizations (especially hospitals and those related to the financial sector).
Who is at risk of a Ransomware attack?
Anyone with a computer connected to the Internet and anyone with important data stored on their computer or on the network is at risk.
Government bodies, law enforcement agencies and health systems are not excluded, which, on the contrary, are often the preferred victims, precisely because of the nature of the data they store.
What are the impacts of an attack?
Ransomware can have devastating consequences for an individual or an organization.
Some victims pay to recover their files but, in reality, there is no guarantee that they will recover their files by doing so.
Recovery can be a difficult process.
For this it is best that you rely on a specialist like HelpRansomware.
Ransomware attacks can create problems in business processes and leave organizations without the data they need to operate and deliver critical services.
Depending on the ransomware types, the damage can be more or less superficial.
On the other hand, the monetary value of ransom requests has increased, with some requests exceeding a million dollars.
Ransomware attacks have become more destructive in terms of reputation as well as economics.
How do cyber attackers use ransomware to attack their victims?
Malicious cyber attackers have adapted their ransomware tactics over time to include blackmailing victims.
You may be threatened to have your data published if you refuse to pay the ransom.
As a secondary form of extortion, they may tell you that you will be publicly shamed.
Alternatively, attackers can go the wrong way, targeting critical data and propagating ransomware across entire networks.
Tactics are increasingly diverse, one of them being the deletion of system backups, which make retrieving and restoring files more difficult.
Who are the attackers?
It can be people trying to damage critical infrastructure or cybercriminals trying to get rich.
Are there any precautions against ransomware?
The following precautions can help protect you from the ransomware threat:
1) Update software and operating systems with the latest patches: Outdated applications and operating systems are the target of most attacks.
2) Do not click on links or attachments inserted in unsolicited e-mails or the sender of which you do not know.
3) Back up your data regularly and keep it on a separate device and store it offline – this won’t help you prevent a ransomware attack, but it sure can help you minimize data loss.
4) Browse securely when your devices connect to the internet.
What are other best practices against ransomware?
These small steps are useful to individuals who are victims of ransomware, but also to organizations.
1) Restrict user permissions to install and run software applications and apply the “least privilege” principle to all systems and services. Limiting these privileges can prevent malware from running or, at the very least, restrict its ability to spread across the network.
2) Use the application authorization list to allow only approved programs to run on a network.
3) Enable powerful spam filters to prevent phishing emails from reaching end users and authenticate incoming emails to prevent email spoofing.
4) Scan all inbound and outbound emails for threats and filter executable files so they don’t reach end users
Configure firewalls to block access to known malicious IP addresses.
