What is Aieou ransomware?

Aieou ransomware – cryptovirus that asks 1 Bitcoin for file decryption

Aieou ransomwareAieou ransomware is a computer virus that might result in personal file loss

Aieou ransomware is a virus that is created for money extortion. Criminals behind the threat focus on getting cryptocurrency. As soon as the malware gets access to a computer, it immediately starts non-system data encryption. All users' personal files are appended with a .aieou extension. From that moment, victims won't be able to open those files until they pay a ransom.

After the lockage of non-system files is completed, a ransom note named “README.txt” is created inside all affected folders. The message itself is very brief and just informs the victims that their files are encrypted and that a staggering 1 BTC (one Bitcoin) is required to unlock them. Then a contact email is provided – victims are asked to send an email to Although the Bitcoin price fluctuates, it's equivalent to around thirteen thousand dollars. If users haven't kept backups, paying the cybercriminals might seem like the only way out. As always, we advise against it.

Ways cybercriminals are using to infect devices

Cybercriminals' job is to trick gullible people and to infect their computer systems. There are many types of malware, created with different purposes, but one goal – getting paid. Perpetrators can steal user bank, social media, or other logins with Trojan horses[3], encrypt their sensitive data with ransomware, etc.

The internet is full of viruses hidden in various places. The most common ways malware is spread is via spam emails and file-sharing platforms, such as The Pirate Bay, BitTorrent, and so on. Cyberthieves can camouflage their creations as many different file types, .txt, .exe, .pdf, to name just a few.

Always keep an eye on what you're clicking on in the email. Viruses might be hiding in mischievous hyperlinks or infected attachments. Malware on torrent sites is usually disguised as “crack” (illegal activation tool) files, game cheat codes, illegal software installers, or updaters. If possible, try to steer away from such sites and use only genuine apps downloaded from official developer websites.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
