What is Arai Ransomware

Arai is a malicious program that targets corporate users to encrypt business data and demand victims pay money for its return. While restricting access to data, the virus alters files with the .araicrypt extension leading to blank icons as well. For instance, a file like 1.pdf would change to 1.pdf.araicrypt and lose its original icon. After this, data becomes inaccessible and no longer usable. The next step Arai does is creating a text note called READ_TO_RESTORE_YOUR_FILES.txt

This note gives clarification on what happened and how victims can recover from it. In short, cybercriminals inform that all important data (databases, customer data, etc.) has been copied and local backups have been deleted. It is also said that in case of non-compliance with the provided instructions, victims will lose a chance to recover the data and also become subject to suffering both financial and reputational – due to potential data publication that may ensue afterward. Otherwise, victims should contact the swindlers using one of the given email addresses and pay for decryption (supposedly expensive and in cryptocurrency). In such a case, the extortionists promise to wipe out the collected data and not publish it, therefore. Unfortunately, trusting threat actors is also a risk meaning your data can still be published and promised decryption tools may not be given. The problem with such infections is that they put victims to facing dead end where all recovery options have their risks. Trusting cybercriminals is not recommended while discompliance may also outflow in potential data publication. In addition, it is also worth noting that data decryption without the help of cybercriminals is very complex and oftentimes even impossible. The only most likely option is to recover files using backups of it. If you have them available and non-infected, then file recovery is not a problem and it is only data publication that victims may be afraid of. In our guide, you will also find information about general recovery and decryption tools used in recovering ransomware damage. However, it is very possible that their capacity will not be enough to succeed in decrypting your data – but you can still give them a try if no other option is present. Note that prior to trying any of the above-mentioned recovery methods, the ransomware virus must be deleted from your system to prevent its malicious activity. Feel free to use our guidelines to do it as well.

How Arai Ransomware infected your computer

Infections like ransomware seek distribution through phishing-type channels. A virus of such may be disguised as some legitimate-looking file (e.g., Word, Excel, PDF, EXE, JavaScript, RAR, ZIP, etc.) and be part of e-mail spam letters. These letters often present information explaining the “importance” of opening such files (or links). They exploit the names of popular parties (Delivery companies, Tax Authorities, Banks, etc.) to make users believe such messages are valid in what they claim. Unfortunately, following what such spam messages say will most likely lead to malware ending up on your system. Thus, it is important to avoid such e-mail letters and double-check the information you get into the inbox or spam folder. Apart from this, many infections may also target users via fake software installers or updates, malicious cracking tools, system vulnerabilities, backdoors, keyloggers, and other types of suspicious channels as well. To be more protected against such threats in the future, we recommend you read our guide below and learn more practical tips on this topic.
