Questions about HappyDayzz ransomware virus

HappyDayzz virus is a new Globe 3 ransomware spin-off [1] which encrypts computer data using a Public key and pushes the victim into buying out the Private key to be able to decrypt them [2]. Those of you who follow cyber security news closely may already be familiar with this virus as ransomware. This email address is the ransomware victims’ only chance of contacting the extortionists and redeeming encrypted files. Of course, collaboration with the criminal parties is extremely risky, but sometimes, the victims have no other choice but to pay. This is especially common in cases when ransomware targets major companies or organizations and puts them at the risk of losing the voluminous amount of information and client data [3]. Nevertheless, self-respecting organizations and companies typically have backups of their data stored somewhere safe and can easily restore this information from the archives in times of need. Unfortunately, keeping data backups [4] is not a common practice among home users. When ransomware infects their devices, it usually causes a lot of panic and stress, and eventually, the victims succumb to the extortionists’ demands. If you are infected with this virus, we must warn you not to fall for the promises of quick data decryption and keep your wallet shut.

HappyDayzz may take bits and bobs from other ransomware. Nonetheless, it is unique enough to be regarded as an individual cyber threat. One of the most salient characteristics of this virus is how it affects encrypted files. Apart from rendering them inaccessible, the virus also changes their filenames, adds contact email and pins an extension .happydayzz at the end. This feature may cause major inconveniences because even in a case of successful decryption, the filenames will maintain their jumbled up form and the victim will have to employ manual labor to rename them. Another feature that is typically considered as a defining feature of ransomware is its ransom note. HappyDayzz employs the ransom note format taken from Globe virus. The hackers do not even bother to change its title and leave the original How To Recover Encrypted Files.hta used by Globe. Nevertheless, the note serves its purpose and explains what exactly has happened to the computer and how to fix it. Typically, the victims are demanded to pay a sum of money that corresponds to the volume and importance of the encrypted data. If you have no valuable files on your device, it is best that you carried out HappyDayzz removal and cleaned up your device to be able to use it again. In case you do have some files on your device that you need to recover, feel free to use alternative data recovery recommendations below the article.

How did your computer get infected with this ransomware?

The malware distributors often think of creative ways to make the users download such attachments without suspecting they are actually allowing a ransomware virus on their devices. The hackers typically work under the names of popular banks, government institutions, companies or social media networks just to get more people get involved in their scam. Please keep in mind that though hackers use and email addresses to contact their victims, they won’t use the same addresses when spreading spam mail around. So, you must be very careful and vigilant when navigating through your email and downloading attachments.
