T1Happy virus Removal Guide

What is T1Happy ransomware?

T1Happy ransomware is a file locker that does not ask users to pay ransom

T1Happy ransomwareT1Happy ransomware is a file locker that operates AES encryption algorithm to encrypt data and appends .happy file extension

T1Happy ransomware is a cryptovirus that is a little bit different from your typical viruses of such kind. While it is a fully functional malware, it seems like hackers behind it only want to teach victims a lesson in order to make sure they do not get infected wit ha real threat that would result in file loss. Once infiltrated, T1Happy virus obtains admin rights without prompting User Account Control warning on Windows systems and performs a full system scan, looking for most commonly used files like databases, documents, pictures, videos, etc. It then executes an encryption process by using AES cipher and adds a .happy extension, preventing users from accessing data. Additionally, T1Happy ransomware drops a ransom note HIT BY RANSOMWARE.txt which explains that damage done is reversible but might not be next time.

According to the analysis, the IPLogger link of T1Happy ransomware redirects to the official NSA's website, which is pretty ironic considering that the authors of the virus are criminals. Additionally, one of the linked addresses redirects to an unknown domain which displays Bad Rabbit ransom note.

Ransomware is distributed with the help of a variety of techniques, including brute-forcing, exploit kits, repacked installers, fake updates, etc. However, due to the contents of the ransom note, it is highly likely that T1Happy ransomware authors used spam emails to infect victims:

In order to decrypt your files, you must decompile the ransomware (which is easy) and find out the encryption method (easy aswell)
Next time, think before your execute. Your next ransomware could'nt be that easy to crack and you would lost all your files 🙁

Evidently, the developers of malware do not wish to obtain your money, as there are no demands, contact emails or Bitcoin addresses present in the message. However, the infection is real, and T1Happy ransomware removal is a step that should be done before proceeding with file recovery.

To remove T1Happy ransomware, you should employ reputable anti-malware software that recognizes the threat, and we suggest using FortectIntego or SpyHunter 5Combo Cleaner, although other tools can be used as well. Eliminating the virus manually should only be performed by trained IT experts.

Spam emails help ransomware reaching multiple users worldwide

Hackers are not asking for any payment after the infection. However, it should serve users as a warning as to how easy it is to infect your PC with a cryptovirus. Ransomware and spam emails go together for a very long time, and it has been one of the most prominent distribution methods of malicious software for years.

Security experts[1] recommend employing security software and be careful while browsing the internet:

  • Do not casually open spam email attachments or click on links;
  • Protect your system by applying security patches regularly;
  • Scan downloaded files with help of such tools like Virus Total;
  • Avoid high-risk websites, such as gambling, porn, free online gaming, and similar;
  • Use adblock;
  • Use strong passwords or a password manager, as well as two-factor authentication;
  • Do not believe everything you see on the internet – it is easy to obfuscate a malicious file with hyperlinks, buttons, and similar methods.

T1Happy removal steps

It is unknown why T1Happy virus developers deployed it since they do not receive any benefits from infecting users. However, to some degree, it could serve as a message to those who did get infected. Because file decryption is possible, victims can get away with minor inconvenience, while real ransomware infection might result in permanent data and money loss.

To remove T1Happy ransomware, you should download and install a reputable anti-virus engine. In case T1Happy ransomware tampers with anti-virus operation, we provide instructions below how to enter Safe Mode with Networking.

According to security experts,[2] the malware is decryptable, so users should contact them for help. Alternatively, you can rely on backups or third-party software to retrieve access to your data. However, do not forget to perform T1Happy ransomware removal before you proceed with file recovery, as they can get encrypted again.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
