What is Aperfectday2018 ransomware? And how does it execute its attack?
Aperfectday2018 ransomware is a data-encrypting virus that was found in the web at the beginning of November 2018. It uses the “[email protected]” email address which is where it got its name. This crypto-malware is programmed to encrypt targeted data using the AES cipher and then use a public key to encrypt files making them inaccessible to users. It mostly targets users from Denmark although that does not necessarily mean that it can’t infect other users all over the globe.
Once it infects a computer, it drops its payload file and connects the system to a remote server controlled by the attackers. From this remote server, several malicious components will be downloaded and placed on system folders which help the crypto-malware in executing its attack. It then employs an information gathering module used to obtain data about the infected user and the system. Following that, it also uses a stealth protection module used to bypass any security programs in the system by analyzing what software is installed and then searching and disabling antivirus engines. Once these two aforementioned modules are completed, Aperfectday2018 ransomware will scan the computer in search for its targeted files and after it finds them it encrypts them and appends the (enc) string to the affected files. It also drops a file named “aboutYourFiles.txt” which contains the following message:
“Hi. Thank you for using my program. If you’re reading this, a lot of your files have been encrypted. To decrypt them, you need my decryption program. For this, I want 25 000 sek, I want them in bitcoin. Email me when you’ve paid with details about the transaction. I’ll give you two days.
If you have not paid in two days(from the day you received the email), It will cost 1000 sek more per day.
If I have not heard from you after five days (from the day you received the email), I assume your files are not that
important to you. So I’ll delete your decryption-key, and you will never see your files again.
After the payment, email me the following information:
* the bitcoin address you sent from (important, write it down when you do the transaction)
* the ID at the bottom of this document (this is important!! Otherwise I don’t know which key belongs
Then I will send you the decryption-program and provide you with instructions of how to remove
the virus if you have not already figured it out.
Make sure to get the bitcoin adress right, copy and paste and double check. If you send the bitcoin
to the wrong adress, it will be lost forever. You cant stop or regret a bitcoin transaction.
Do not loose this document. You also have a copy of it on your desktop.
Do NOT change any filenames!!! !!!
Thank you for the money, it means a lot to me.
