The latest ransomware, users have complained of, goes by the name Corp. They’ve come to calling it that, courtesy of the extension it appends, when it strikes. Let’s explain. Corp belongs to the Paradise family of threats. The ransomware slithers into your system via deception. Then, once inside, spreads corruption. The tool uses RSA cipher algorithm. To encrypt your data. All your files get affected. Music, videos, documents, archives, pictures. Everything, you store on your computer, gets locked. The infection adds a special extension at the end of each file. Thus, making it unreachable. Here’s an example. Say, you have a photo called ‘1.jpg.’ That turns into ‘1.jpg_%ID%_{alexbanan@tuta.io}.CORP.’ Once the extension gets put into place, you can no longer access your files. Moving and renaming them is a futile effort. They’re under lock-down. The only way to change that is to comply with the cyber kidnappers’ demands. After encryption, the infection leaves you a ransom note. It’s called $%%! NOTE ABOUT FILES -=!-.html. It explains your current predicament, and contains instructions. Do NOT follow these instructions! The extortionists try to get you to pay them money for your files. They promise that, once you pay up, they’ll send you a special decryption key. Apply it, and your files get unlocked. All that seems fine and dandy, but ask yourself the following. Can you trust cyber criminals to keep their word? The answer is ‘No.’ Don’t take any chances. Don’t waste your money. Say goodbye to your files, and move on. Put your faith in backups. Use cloud services and external storage. The fight against a ransomware is not one, you can win.

How did I get infected with?

How do you imagine you get stuck with Corp? Well, like most infections online, it uses your carelessness as a way in. The tool turns to the old but gold invasive methods to gain passage into your PC. It hides behind freeware, corrupted sites, or torrents. It can pretend to be a fake system or program update. Like, Java or Adobe Flash Player. And, of course, it uses spam emails. One day, you receive an email from a well-known company. It seems legitimate so you open it to discover an attachment, or a specific link. The email reads that you must click said link, or download said attachment. They pose as confirmation links, invoices, receipts, anything. Click nothing! Don’t give into naivety. Always make sure to know what you open, press, download. Even a little extra attention can save you a ton of troubles. Do your due diligence. Caution helps to catch cyber threats in the act of attempting invasion. Carelessness helps them sneak by you, unnoticed. Don’t ease their infiltration. Spot them trying to slip by undetected, and prevent them from doing so. Choose caution over carelessness.

Why is Corp dangerous?

As soon as Corp strikes, you face a conundrum. You have a choice to make. Give into fear and naivety, and comply. Or, keep level-headed, and make the tough, but right, call. Here’s the thing. Even if you follow these people’s instructions to the dot, you won’t get your files. Think about it. There are countless ways for them to double-cross you. If you pay the ransom, you wait to receive a key, they promised to send. But what if they don’t? Or, what if they give you one that doesn’t work? And, even if they send the right one, don’t rejoice yet. The decryption key removes the encryption. The infection that did the encryption remains. And, it’s free to strike again. It can lock your data a mere minute after you apply the key. What then? Are you going to pay again? Don’t put your faith to the mercy of cyber criminals. They’re unreliable and malicious. Don’t pay. Cut your losses, and discard your data.
