Happychoose ransomware – a new cryptovirus in the Globeimposter ransomware family

Happychoose ransom note

Happychoose is a dangerous cyber infection that attempts to lock files with .happychoose extension and demand a ransom in exchange for the decryption key. Victims started searching for help to encrypt data attached by this file-encrypting malware[1] at the end of February 2020, thus exposing a new evolving threat. Initially, Happychoose ransomware might seem like a unique piece of crypto-virus, but closer analysis reveals that it's a member of an infamous GlobeImposter family. Distributed through spam, it attacks random PCs by happening unreadable extensions to files and creating a ransom note named “Decryption INFO.html.” 

Happychoose ransomware virus creates the Decryption INFO.html on every system's folder that contains files locked with .happychoose extension. The note contains a list of demands and instructions. Cybercriminals encourage victims to contact them asap via happychoose@cock.lt or happychoose2@cock.lt email. Crooks demand the victim to send an email that contains one locked file and a unique ID code that is provided on the note. The size of the ransom is not indicated. According to the information, it will be revealed only when ransomware developers receive the victim's ID and evaluate the amount of locked data. 

Name Happychoose
Origin GlobeImposter 2.0 ransomware family
Distribution Unprotected Remote Desktop, spam email attachments, drive-by-download attacks
Symptoms Upon Happychoose infiltration, most of the files present on the target system receive .happychoose file extension. The ransom note “Decryption INFO.html” appears on the desktop. Multiple registries on the system are compromised. The overall system's performance may diminish significantly.

Removal The only way to eliminate Happychoose ransomware is to launch AV tool and run a full system scan. Any professional antivirus tool with a powerful detection mechanism is appropriate, though we recommend SpyHunter 5Combo Cleaner or Malwarebytes
Data recovery There are two options – to pay the ransom or use third-party data recovery tools to decrypt corrupted files. Paying the ransom is not recommended in any way. For more information on how to unlock files after Happychoose attack, see the end of the post. 
System's repair Ransomware can severely damage multiple Windows Registry entries and initiate other disruptive modifications. To fix any system's damage, use Reimage Reimage Cleaner Intego repair utility. 

Happychoose virus renders a unique cipher to encrypt data on a target computer. The virus runs the cipher by taking advantage of the infected cmd.exe file, as well as other vulnerable Windows Registries. The powerful ransomware scanner is capable of tracking over 34 file types and inject the .happychoose suffix to each of them. The extension may also contain an email address of the developers or other ransom looking codes. Another thing proving the fact that the system has been infected is Html file Decryption INFO. The ransom note states: 

ALL YOUR FILES ARE ENCRYPTED!

ALL YOUR IMPORTANT DATA HAS BEEN ENCRYPTED.

To recover data you need decryptor.

To get the decryptor you should:

Send 1 test image or text file happychoose@cock.li or happychoose2@cock.li.

In the letter include YOUR ID (look at the beginning of this document).

We will give you the decrypted file and assign the price for decryption all files

After we send you instruction on how to pay for decrypt and after payment you will receive a decryptor and instructions. We can decrypt one file in quality the evidence that we have the decoder.

Attention!

Only happychoose@cock.li or happychoose2@cock.li can decrypt your files

Do not trust anyone happychoose@cock.li or happychoose2@cock.li

Do not attempt to remove the program or run the antivirus tools

Attempts to self-decrypting files will result in the loss of your data

Decoders other users are not compatible with your data, because each user's unique encryption key

Although criminals do not reveal the size of the ransom, it may be assumed that the payment varies from 1 to 10 Bitcoins. Such assumptions are based on its ancestor, GlobeImposter 2.0 requirements. Happychoose encryptor may be a severe problem and money stealer for those who are not used to backup files. Since the decryption for this malicious infection hasn't been created yet, there's no other way to get data back except to pay the demanded ransom. Nevertheless, a deal with criminals is always a risk. 

Happychoose ransomware virus informationHappychoose ransomware developers urge victims to contact asap and pay the ransom for the decryption tool

Developers of this cyber infection try to raise people's fair, claiming that any attempts to decrypt files encrypted by Happychoose ransomware manually may lead to a permanent data loss. Even more, a risk to cause perpetual data lock is the usage of automatic antivirus and recovery solutions. However, there's no clear evidence that third-party data recovery tools cannot repair damaged files. Therefore, we strongly recommend victims to remove Happychoose with tools like SpyHunter 5Combo Cleaner and then install a reliable data recovery software, which may turn out to deal with ransomware cipher successfully. 

Checking malicious email attachments – a straight way to a ransomware attack

Dieviren.de[2]  and other security experts keep trying to warn Internet users about spam emails, which is by far the most widely used technique to spread various malware and virus types. Cybercriminals keep developing botnets that are later used for massive spam attacks. Such messages are typically filled with infected with ransomware, spyware, trojans, and other viruses. Usually, attackers do research on people's preferences and make the infected emails look credible and professional. The more legitimate the email looks like, the more recipients are expected to open them. 

Having this in mind, it's a must to carefully analyze all emails that contain attachments before double-clicking on the file. Look for grammar or type mistakes, check the sender online, and think twice does the email really has any information that is relevant for you. If you are not sure, you'd better not open the attachment. 

In addition to spam, ransomware can be deployed by clicking on the malicious links on unprotected websites or social network messages. Unprotected Remote desktop, as well as drive-by-download attacks, are also among conventional ransomware distribution means.

We want to stress the fact that GlobeImposter 2.0 ransomware family has been noticed on the landscape in 2019 and is ranking third with 12.57%[3], among other ransomware-type infections. It shows that impostors that are responsible for disseminating Happychoose and GlobeImposter are going on the right way looking from cybercriminal's perspective. Therefore, to protect your files and PC from severe attacks, take care of a proper system's security and try to be more suspicious when browsing the Internet. 

Delete Happychoose ransomware pack from the system

Happychoose ransomware virus is currently in an active transmission phase, security forums reveal. If its developers managed to successfully upgrade GlobeImposter 2.0 and release it with a new strength, the prognosis on the infection rate might be saddening. 

The removal of Happychoose may be a tough nut to crack as most of the ransomware are incredibly resistant to detection. This threat may be programmed to block AV tools and other security programs, as well as take care of the complete removal of Windows Shadow Copies. Therefore, you may need the help of professional IT experts to clean the system and get at least some of the files back. 

Anyway, we highly recommend trying an automatic Happychoose removal with a reliable security tool. To bypass AV blockade, boot the system into Safe Mode and run SpyHunter 5Combo Cleaner, Malwarebytes, or an alternative program. You can learn how to do that with the help of the instructions provided below. As for encrypted files, antivirus software will not be able to revert the changes that the ransomware initiate.

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. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

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 server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

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. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

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

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
