Ako ransomware removal instructions

What is Ako?

There are two variants of Ako ransomware, however, the only difference between them is the way victims supposed to contact cyber criminals/pay a ransom. Both variants of Ako create a text file (ransom note) named "ako-readme.txt". In one version of ransom note victims are instructed to contact cyber criminals via email, in another one - to pay a ransom through a Tor website. Both Ako variants create the "id.key" file and drop it in folders that contain encrypted files (they do the same with the ransom note) and rename all encrypted files by appending a random extension to their filenames. For example, a file named "1.jpg" gets renamed to "1.jpg.2mzWmb", and so on.

In both versions of ransom note ("ako-readme.txt") victims are informed that all their files were encrypted and the only way to decrypt them is to purchase a unique key. One version contains two emails ( and that should be used to contact cyber criminals (Ako developers) for more details on how to purchase that key. Another version contains a website link that can be opened with a Tor browser. On that Tor website victims have to paste the personal ID from the second version of the "ako-readme.txt" text file and then follow the instructions. As stated in that website, victims can purchase a decryption tool by transferring 0.479 of Bitcoin to a provided BTC wallet address. It is also mentioned that if a payment will not be made in two days after encryption, then a price of a decryption will be increased to 0.9576 of Bitcoin. It is true that Ako developers are the only ones who can help their victims to decrypt encrypted files. There are no other tools that could be capable of that, at least not at the moment. However, the problem with most cyber criminals behind programs of this type is that they cannot be trusted. Quite often they do not provide decryption tools and/or keys even after a payment, in other words, people who pay them get scammed. In most cases the only free way to recover files/avoid data loss is to restore them from a backup. It is worth mentioning that files remain encrypted even if victims remove ransomware from the operating systems, its removal only prevents if from causing further encryptions.

Ako decrypt instructions (ako-readme.txt)

Most ransomware-type programs are designed to block access to data and provide instructions (create a ransom note and/or display a pop-up window) on how to buy a tool/key that can decrypt encrypted files. Two main and most common variables are size of a ransom and cryptographic algorithm (symmetric or asymmetric) ransomware uses for encryption. Either way, in most cases it is impossible to 'crack' caused encryptions and the only way to decrypt files is by using a tool that only developers of a particular ransomware have. It is possible to avoid data and monetary loss without having to use their tools only when ransomware is not finished (contains bugs, flaws and has other vulnerabilities) or by restoring files from a backup. In such cases data backups become extremely useful and that is why we strongly recommend to always have data backed up and keep it on a remote server or unplugged storage device. A couple of examples of other ransomware are m461c14n, WannaScream and Pashka.

How did ransomware infect my computer?

Most cyber criminals spread ransomware-type software (or other malware) via spam campaigns, fake software updaters, untrustworthy software download sources, unofficial software activation tools and Trojans. One of the most popular ways to spread malware is by sending emails that contain malicious attachments (or website links that are designed to download malicious files). Quite often these emails contain attachments such as Microsoft Office documents, archives (like ZIP, RAR), PDF documents, JavaScript files, and executable files like .exe. If opened, those attachments install some malicious program, in this case it would be Ako ransomware. Another way to spread malware is through fake software updaters. People who use them to update software often cause installation of some malicious program. Also, tools of this type can be designed to exploit bugs, flaws of some outdated software and infect systems this way as well. Cyber criminals use untrustworthy software download channels to trick people into installing computer infections by themselves. Some examples of untrustworthy sources are Peer-to-Peer networks like torrent clients, eMule, various free file hosting, freeware download websites, third party downloaders, and other similar channels. They present infected files as legitimate and hope that someone will download and open them. If opened/executes, those files usually install one or another malicious program. Software 'cracking' tools supposed to bypass paid activation of software for free. Nevertheless, instead of doing that these tools often install ransomware-type and other malware. Trojans are programs that often are designed to spread other malware. Simply said, if a computer is infected with a Trojan, then it is very likely that it will cause additional damage.

How to protect yourself from ransomware infections?

If an email is received from unknown, suspicious address, it is irrelevant and contains some attachment or website link, then it should not be trusted. It is very likely that such email is would be sent by some cyber criminal who seeks to infect a computer with ransomware or other malware. Also, software should not be downloaded from unofficial pages, through Peer-to-Peer networks or other sources that we mentioned in the paragraph above. It should be downloaded only from official websites and via direct download links. Software must be updated and/or activated through tools or implemented functions that are designed by official developers. Unofficial, third party tools can be designed to spread malicious software. Besides, it is not legal to activate paid software with various 'cracking' tools. One more important thing is to regularly scan the operating system for threats with a reputable antivirus or anti-spyware software regularly and always eliminate detected threats as soon as possible. If your computer is already infected with Ako, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Update January 16, 2020 - Cyber criminals have recently started various email spam campaigns to spread Ako ransomware. These emails contain various messages that present malicious attachments as various documents and encourage recipients to open them. The sample we analyzed had a password-protected .zip attachment ("") which contained an executable ("agreement.scr"). Once executed, this file injects Ako ransomware into the system:

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Ako ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Ako are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by Ako, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.
