There’s a new ransomware, plaguing users. And, it goes by the name Qwex. It derives from the extension, you get stuck with, after it strikes. Let’s elaborate. Qwex is a new variant of the Dharma menace. It uses slyness to invade your system, then corrupts it. The tool uses cryptography algorithms to lock your data, and take it hostage. It encrypts every single file, you have. And, demands payment for their release. It’s a classic ransomware extortion scam. Once the tool settles on your system, its programming kicks in. You discover your archives, photos, videos, documents, everything, locked. A picture called ‘yes.jpg‘ turns into ‘yes.jpg.id-1E857D00.[backdata@qq.com].qwex.’ After the extension is in place, that’s it. Your data gets rendered inaccessible. And, the only way to change that, is via unique decryption key. Of course, to get it, you have to pay the price. The exact ransom amount isn’t specified. But it tends to be in Bitcoin, and varies anywhere between $500 and $1000, or even more. There’s no limit to the greed of the cyber kidnappers. Don’t forget that. You’re dealing with malicious extortionists. Cyber criminals, who wish to profit off of you. Ask yourself. Can you trust these people to keep their word, and follow through with their promises? The answer is ‘No.’ You can’t. So, don’t! Don’t sen these people a dime. Don’t contact them. Compliance is a risk that brings no positives, so don’t take it.

How did I get infected with?

Ransomware, like Qwex, are pretty sneaky. They turn to the usual trickery, when it comes to invasion. Hiding behind freeware, spam emails, corrupted torrents, fake updates. They have quite a few options to choose from, and try to invade. It’s up to you to prevent the tool’s success. Here’s the thing. These types of threats need your carelessness to infiltrate. They need you to rush, and give into naivety. To leave your fate to chance, and not do any due diligence. They need you to choose carelessness over caution. Don’t. Vigilance helps you catch infections in the act of attempting invasion. And, prevent them from doing so. The lack thereof leads to them slipping by you, unnoticed. Carelessness has consequences. Make sure to take your time, and be thorough. Even a little extra attention can save you a ton of troubles.

Why is Qwex dangerous?

Once Qwex places your files under lock-down, it leaves you a not. It’s a text file, called “FILES ENCRYPTED.txt.” And, it contains instructions for you to follow. It’s pretty standard. The tool explains your situation, and gives you a way out. Supposedly, if you complete its requests, you’ll get your files unlocked. It wants you to contact the cyber kidnappers via email. The same one, you can see in the extension. It expects you to write them within the first 24 hours of encryption. And, claims that, if you do, you’ll pay less. The ransom amount increases the more time passes. That’s yet another tactic to get you to act against your best interests. Do NOT fall for it, and don’t pay! There aren’t enough ways to stress that! Think about it. You have ZERO guarantees that compliance gets you anything. All, you have to go on is the extortionists’ promise. “Free decryption as guarantee.” That’s hardly enough. Examine your options. If you pay the price, you’re left waiting to get the decryption key. What if you don’t? Or, what if you get one that fails to work? And, even if you get the right one, don’t rejoice. You paid to remove a symptom, not the infection. So, even if you do unlock your data, the ransomware still lurks on your PC. And, it’s free to strike again, and put you back to square one. Heed experts’ advice. Don’t pay the ransom.
