How damaging is Access ransomware?

Access can be correctly summarized as a typical ransomware-type infection.
Ransomware stands for a special kind of software that introduces unwanted alterations with your documents and then forces you to pay the specific amount of money to restore them. Access was first revealed and analyzed by Michael Gillespie1.

Access belongs to the Djvu ransomware family. Its activity is basically similar to other representatives of the same family: Ndarod, Ntuseg, Bopador. It modifies all common file types though encrypting them. Hence, people cannot open the files as soon as they are encrypted. Access adds its particular “.access” extension into all file modified by it. For instance, the file “report.doc”, once ciphered by Access, will be amended into “report.doc.access”. As soon as the encryption is successfully accomplished, Access drops a specific text document (for instance, “_readme.txt”) and puts it into all folders that contain the encrypted data.

The text file generated by Access asking for the ransom payment is basically similar to other notifications mentioned by the ransomware belonging to the Djvu family. The summary of the alert is that all the documents are encrypted and that the only one solution to restore them is to use a unique decryption key.

The cryptography mechanism applied by Access is not completely investigated. However, it is absolutely true that computer owners whose documents got encrypted may be given a specific decryption key, which is totally unique and there are no other copies of it that would work solely on your device. The sad reality is that it is impossible to recover the information without the unique key available.

Once Access is performing its malicious activity it is impossible for users to gain access to the key, which is stored on a remote server owned by the frauds who distibute the Access ransomware.

The crooks mention that for receiving the key and restoring the amended data, the payment should be implemented in their favor that amounts to $980. To obtain the payment details the victims are encouraged by the message to contact the frauds by writing an email, or via Telegram.

The alert also indicates that the computer owners must get in touch with the Access representatives during 72 hours starting from the moment of data modification. The notice mentions that on the condition of getting in touch within 72 hours users will be granted a 50% rebate, thus the ransom amount will be minimized down to $490). However, no matter what the demanded amount is, stay away from paying the ransom!

Is it a good idea to pay the Access ransom?

If you think that paying the requested ransom is the only way-out, I should mention a few thoughts regarding this decision. The criminals who stands behind the Ransomware surely wants you to think that there is definitely no other option to recover the information.

Definitely, the crooks want the ransom to be transferred via some specific pre-defined channels and sequence of steps. As a matter of fact, this is typically done via Bitcoins as the main currency. The application of Bitcoins is generally the preferred option by cyber frauds because such transfers are very unlikely to get traced.

Considering this peculiarity of Bitcoins, they are applied by hackers that aim to scare the targeted victims through the Ransomware. The technology of such hard-to-trace virtual currency is the main ground why almost all Ransomware frauds manage to remain anonymous after successfully fulfilling their covetous money-stealing missions.

Yet, in many instances, even transferring the requested ransom might not help the virus victims as it is quite possible that they may not be given any file-decryption key. If so, it is a good solution to try some other possible alternatives that might be available – paying the ransom is most certainly not the good way-out and should be the very last item in the list.

Do not pay for ransomware

You cannot trust online frauds since they aren’t concerned what you feel about the trouble with your files, even when you do initiate the transfer of the ransom. This is why paying the money demanded by these frauds does not really fix your problem. Hence, often people just waste their money for absolutely nothing.

I certainly advise that you do not contact these frauds and do not send funds into their pockets. As per now, there are no tools able to crack the Access ransomware or restore the encrypted data. Thus, the one of the real working solution to recover the lost data – just using the available backups.

Access virus message

The scary alert demanding from users to pay the ransom to decrypt the encoded data contains these frustrating warnings

You should be aware that the Internet today is full of viruses that look pretty similar to the Access infection. Malicious programs known as ransomware are typically elaborated to encrypt important files and to mention about the ransom on the targeted screen to eventually force people to transfer the ransom figure into the accounts of the crooks that develop such a kind of malware.

The peculiarity of all such ransomware threats is that they apply a similar set of actions for generating the unique decryption key to recover the ciphered data.

Thus, unless the ransomware is still under the stage of development or possesses with some hard-to-track flaws, manually recovering the ciphered data is a thing you can’t really perform. The only solution to prevent the loss of your valuable data is to regularly make backups of your crucial files.

Note that even if you do maintain such backups regularly, they ought to be put into a specific location without loitering, not being connected to your main workstation.

For instance, the backup may be kept on the USB flash drive or some alternative external hard drive storage. Optionally, you may refer to the help of online (cloud) information storage.

Needless to mention, when you maintain your backup data on your common device, it may be similarly ciphered as well as other data.

For this reason, locating the backup on your main PC is surely not a good idea.

How does Access attack the PC?

Access refers to various methods to spread its roots into the computer. It is not really clear what exact method was used to infiltrate your PC.

How Access infection attack your PC?

Access ransomware attack following a successful phishing attempt.

Nevertheless, these are the common leaks through which it may be injected into your PC:

  • hidden installation along with other apps, especially the utilities that work as freeware or shareware;
  • dubious link in spam emails leading to the Access installer
  • online free hosting resources;
  • using illegal peer-to-peer (P2P) resources for downloading pirated software.

There were cases when the Access virus was disguised as some legitimate tool, for example, in the messages demanding to initiate some unwanted software or browser updates. This is typically the way how some online frauds aim to force you into installing the Access ransomware manually, by actually making you directly participate in this process.

Surely, the bogus update alert will not indicate that you are going to actually inject the Access ransomware. This installation will be concealed under some alert mentioning that allegedly you should update Adobe Flash Player or some other dubious program whatsoever.

Of course, the cracked apps represent the damage too. Using P2P is both illegal and may result in the injection of serious malware, including the Access ransomware.

To sum up, what can you do to avoid the injection of the Access ransomware into your device? Even though there is no 100% guarantee to prevent your PC from getting damaged, there are certain tips I want to give you to prevent the Access penetration. You must be cautious while installing free software today.

Make sure you always read what the installers offer in addition to the main free program. Stay away from opening dubious email attachments. Do not open files from the unknown addressees. Of course, your current security program must be always updated.

The malware does not speak openly about itself. It will not be mentioned in the list of your available programs. However, it will be masked under some malicious process running regularly in the background, starting from the moment when you launch your computer.

The message by the Access ransomware states the following frustrating information:
