Aperfectday2018 Virus – Distribution Techniques

The Aperfectday2018 virus was discovered in an attack campaign. As the ransomware sum is not requested in BTC but SEK we anticipate that the operators originate from Sweden or are Swedish-speaking themselves. The attack is limited in number which shows that it may be directed at a narrow target. The virus strains may also be test versions or an early development build.

One of the most common strategies to deliver ransomware like this one is the distribution of email SPAM messages that contain various social engineering scenarios. Their primary goal is to confuse the recipients into thinking that they have received a message from a service or site that they use. The actual virus files are linked in the body contents — they pretend to be software updates or installers of legitimate applications. In other cases they can be attached directly to the messages.

A related tactic is to build fake Internet portals which can lead to a virus infection. Together with the emails they are among the most popular tactics for spreading infected payloads. Most of the viruses that are spread today are of two main types:

  • Infected Software Installers — The criminals can also modify setup files of popular software: creativity suites, system utilities and productivity software. They are made by taking the legitimate installers from their official vendor sites and modify them with the virus code. This means that a legitimate software will be installed together with the Aperfectday2018 virus.
  • Infected Documents — The other source of infections may come from documents containing dangerous macro scripts. Such examples can be the most popular formats: spreadsheets, presentations, databases and rich text documents. Once they are opened by the users a notification prompt will be spawned asking the users to enable the macros. If this is done the scripts will trigger the virus download commands.

Both the infected payloads and stand-alone virus files can be distributed over file-sharing networks like BitTorrent. They are used to spread both legitimate content and pirate copies of software and games.

Large-scale campaigns can be spread using browser hijackers — malicious and purpose-made extensions for the most web browsers which are uploaded to the respective repositories. Usually the hackers will also use fake user reviews and developer credentials in order to further coerce the users into installing them. When they are run by the users the virus payload will automatically be downloaded alongside the other options configured within. This is usually a redirect code that will change the default settings to point to a preset hacker-controlled page.

Aperfectday2018 Virus – Detailed Analysis

The Aperfectday2018 virus by itself does not appear to originate from any of the well-known malware families. There are two main hypotheses behind its origins. The first one is that this may be a custom creation by the same hackers that are responsible for its distribution. The other possibility is for them to pay hacker developers in the underground communities.

The captured samples so far demonstrate only the presence of the encryption engine alone. However it is very possible that updated versions will feature a much more complex behavior pattern.

Such attacks can begin with information gathering — the built-in module will harvest data that can be categorized into two main groups:

  • Identity Revealing Information — These strings are used to expose the identity of the victim users. The strings that are hijacked can include their names, address, interests and any stored username and password combinations. A very dangerous characteristic of such virus infections can scan both the operating system storage and the data of the third-party installed applications.
  • Machine ID Values — The engine can harvest the required strings that are needed to assign each infected computer an unique ID. It is generated through an algorithm that processes the input data and returns this ID. Most of the ransomware engines that engage this module use a combination of strings taken from the list of installed hardware components, user settings and certain operating system variables.

The hijacked data can be used by another component that handles the security bypass. By analyzing what software is installed on the victim machines this module will search for and disable anti-virus engines. Some of the advanced strains have the ability to check if they are running inside virtual machines or sandbox environments and the disable the hosts.

After these two modules have completed the Aperfectday2018 virus will be able to take over control of the victim machines. In most cases this is associated with Windows Registry modifications. The engine can access, modify or delete entries that belong to the operating system or any of the user-installed applications. The consequences upon the users will be the inability to launch certain functions, services and an overall problem with system performance.

A related action is the set-up of the ransomware as a persistent infection. It will be started automatically when the computer boots and it may also disable certain services and the ability to enter into the recovery boot menu. This practically disables the ability to use most manual removal instructions. In such cases the victims will need to resort to an advanced anti-spyware solution, refer to our instructions for more details.

To make recovery even more difficult the engine can also remove data such as Shadow Volume Copies or Backup Images.

A very dangerous case is where the ransomware engine installs a Trojan horse infection. Their default configuration is to set up a client connection to a hacker-controlled server. It allows the operators to spy on thr victims in real-time and overtake control of the infected computers at any given time. This allows the hackers to hijack sensitive user data before and after the encryption process, as well as plant additional malware.

In the last few years custom ransomware have been found to install JavaScript Trojan horses. For more information view the wplinkpreview url=”https://sensorstechforum.com/js-redirector-trojan-remove-pc/”]JS/Redirector Trojan removal article.

Aperfectday2018 Virus – Encryption Process

When all of the modules have completed execution the actual ransomware engine of the Aperfectday2018 virus will be started. It will use a strong cipher in order to process sensitive user data which will be come inaccessible. The majority of threats use a built-in list of target file type extensions. An example list may include the following data:

  • Archives
  • Backups
  • Databases
  • Images
  • Videos
  • Music

All victim files will be renamed with the (enc) string prepended to the files and the associated ransomoware note will be crafted in a file called aboutYourFiles.txt. When opened it will read a message that coerces the users into paying the hackers a decryption fee in order for them to access their data. We advise all ransomware victims not to interact with the criminals in any way as they will only take the money and will not help the users. Refer to our removal guide below.

The captured ransomware note samples of the Aperfectday2018 virus infections read the following:

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
to you).
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.
Email:
[email protected]
Bitcoin adress:
1LX3tBkW161hoF5DbGzbrm3sdXaF6XHv2D
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.
IMPORTANT:
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.
