How to remove Nemucod-AES ransomware virus

Nemucod-AES ransomware takes victim's files hostage to demand ransom

Nemucod-AES ransomware ^[1] is a data-encrypting virus which earned its title by stealthily infiltrating computers, rendering the containing files unreadable with the help of AES-128 and RSA-2048 encryption algorithms, and demanding 0.11471 Bitcoins for their decryption.

The criminals choose cryptocurrency ^[2] as means of payment deliberately. This method guarantees the anonymity of money transactions and allows the perpetrators to escape prosecution.

That’s why you won’t get any justice if the hackers disappear with your money after you pay for the data recovery key. This should be a sufficient reason to remove Nemucod-AES from the PC rather than collaborate with the criminals.

Typically to most ransomware, the virus developers drop a ransom note on which they list out all the data recovery conditions and instruct victims where they should purchase and transfer the ransom. Here is a transcript of Decrypt.hta file:

Ransom notes can tell a lot about the ransomware developers, their target audience, and their true intentions. In this case, we have to admit that the note is professionally made and detailed, so the hackers behind it are probably native English speakers and serious enough not to leave spelling or grammatical errors on the note.

The ransomware’s target audience is most likely English as well, though it should not stop the virus from infecting users in the European countries, say, Germany or Sweden ^[3].

Despite where in the world the virus hits, the first thing infected computer owners should do is perform Nemucod-AES removal.

The ransomware is distributed via fraudulent UPS spam

There are several ways Nemucod-AES ransomware can spread around the web. A few of the main vectors may be:

• compromised downloads,
• fake software updates,
• deceptive ads,
• exploit kits.

Nevertheless, the most salient method of Nemucod-AES distribution campaign are spam emails disguised as UPS service notices. In the two examined samples of spam emails, experts found files called UPS ground-Delivery-005156577.doc.js and UPS ground-Receipt-4424638.doc.js which both obfuscated the malicious JavaScript code by imitating regular Word files.

Please remember this deceptive distribution technique the next time you are on your email. Do not download or, not to mention, open the attachments which may have been sent to you by some unfamiliar senders, because it might be that you are allowing a vicious ransomware on your PC.
