What’s Ransomware and How to Eliminate it?

Without a doubt, ransomware is a tragedy. To some extent, it’s worse than any virus. You can cure your device if it gets infected with a Trojan, for instance. But there’s hardly anything you can do to save your folders affected by ransomware. It will encrypt them. You will learn that the files are there but will not have the ability to access them. Unless you choose to provide a ransom to the cybercriminal.

Ransomware definition and variations

So, we’re talking about malware which codes files on a user’s computer or locks it out. It’s one of the most common harmful programs. Ransomware may have different shapes and sizes. But there’s one goal in common: to demand a ransom. And hackers are prepared to devote nights and days creating new kinds of malware. Apparently, the strategy brings money quickly.

How can ransomware work? Well, there are two fundamental sorts of ransomware: encryptors and display lockers. Encryptors code your documents. Instead, display lockers take over the OS and wouldn’t permit access to your device.

Nowadays, encryptors appear to be the best. Some of them not only encrypt files but also delete them. As an Example, Jigsaw. This malware will erase your files until you pay the ransom. It would first tease you erasing several files every hour inside a 72-hour period. And if you don’t, all folders will soon be gone indefinitely.

Here are some kinds of ransomware:

Scareware. This malware uses social engineering actively. The purpose is to convince the user to visit an infected site or buy software which resembles an antivirus, for instance. Some forms throw out pop-up messages and alarms to your screen. Some sorts of scareware may lock users’ computers but usually, it impacts their files.

Doxware. Among the most lucrative attacks for hackers. This is a blend of malware along with a personal data flow. Hackers menace to produce personal photos, conversations, and sensitive documents public unless the ransom is paid.

RaaS. This model reminds of an MLM. The network members do not even require special technical knowledge to distribute the program. Among the most famous examples is Cerber. The ransomware is relatively new but it’s already affected millions of consumers. Its decryptor works with 12 languages. Affiliates get 60% of the profits and revel in an extra 5% for a new aide. The scheme employs a Bitcoin account to launder the cash.

What is Ransomware: Video Tutorial

How can ransomware infect your computer?

There are lots of ways how malware handles to master your system. It frequently uses phishing spam — email attachments that users believe to be trustworthy. The moment you open the attachment, then your computer is infected. And there’s hardly anything to do with that.

Social engineering tools are among the hackers’ favorite. They play with customers’ feelings to gain administrative access to their devices.

Malvertising is another system to deliver malicious software. Hackers will even put money into advertisement space on YouTube and wait until you discover it.

However, there are also aggressive approaches to infect computers. These have nothing to do with customers’ behavior really. They rather look for security holes to infect devices.

When it gets inside, distinct ransomware has distinct strategies to spread. But in the end of the procedure, they’ll make any additional work with your documents impossible. If you don’t pay for a mathematical key to decrypt them or unlock your computer.

Some hackers try to appear decent claiming they are a law enforcement agency. They send a message that the victim violates the law using pirated software, for example. And then they need to pay a “fine”.

Would you become a target?

A ransomware attack is generally more concentrated than malware. Big organizations are of special interest since they’re more inclined to pay the cash. Nevertheless, everyone can become a goal. Among the most massive strikes by WannaCry hit over 200,000 users around the world. It became possible because of a Windows vulnerability.

But as it was already said, organizations and companies appear more attractive to hackers. Generally, they use custom made applications which needs a unique approach to updating. And since there are lots of computers to look after, not every company pays enough attention to this. Additionally, some entities lack funds for adequate antimalware. By way of instance, hospitals that spend money on saving people’s lives rather than computers. But once struck a by ransomware, they’re likely to cover a cybercriminal for restoring their patients’ histories.

How will I know if my device is infected?

Frequently after a ransomware virus settles inside of your computer, it shows no signs of existence. You continue using your documents as you always do. But the malware isn’t sleeping. It’s communicating with the hacker’s server and creating two keys — one to encrypt your documents, another — to decode them. As you can imagine, you won’t have the last one until you pay for it. The described process is brief. You’ll find out that you’re in trouble soon. A ransom message is going to appear on the screen describing the situation and describing your next actions.

The majority of the time, you get 72 hours only to cover the money before it becomes too late to save your information. And do not waste your time trying to open your docs. There’s absolutely not any opportunity to do that with no decoding key.
