What is Gooolag Ransomware

Gooolag is a ransomware infection that makes all stored data cut off from regular access to demand paying recovery ransom. It is more likely to see high-revenue companies infected with this ransomware version. Cybercriminals use the .crptd extension to each encrypted file. For instance, a data piece like 1.xls will change to 1.xls.crptd and reset its original icon. Following this stage of encryption, victims are met with decryption instructions presented inside of a text note called How To Restore Your Files.txt:

How To Restore Your Files.txt

Hello
If you reading this message, it means your network was hacked and all of your files and data has been ENCRYPTED
More than 600 gigabytes of important information was also downloaded.
Do not change the extension on the files, it may cause damage.
Also on top of that, we start ddos of all your domains.
And calls to your entire team, starting with the CEO.
What can you do -
1) write to our emails. As soon as possible.
2) do not interfere with the police and other authorities (they can slow down our communications, after our deal we leave you the right to contact any authorities)
3) Do not invite company recovery. They can also slow down our communications and sometimes even disrupt the deal. (You can invite the recovery company when we complete the deal, and you will receive a decryptor if you want to.)
4) Keep us informed of the processes, obtaining cryptocurrency
5) Do not hold us for fools =)
Contacts for communication.
1 - Gooolag46@protonmail.com
2 - guandong@mailfence.com

The note unveils a world of agonizing information regarding the data. At first, cybercriminals state 600 Gigabytes of important data have been uploaded to anonymous servers. Then, victims are getting punched with some intimidation calls – DDoS (distributed denial-of-service) attacks on entire domains and company contacts. To prevent it from happening and losing the whole data, victims are obliged to contact extortionists using e-mail communication (Gooolag46@protonmail.com or guandong@mailfence.com). Should developers suspect something related to police or cyber authorities, the recovery process will be affected. It is also advised against involving recovery crew to avoid paying the ransom. Gooolag data is less likely to be decrypted without cybercriminals themselves unless there are backup copies available. In this case, however, most companies may be worried about having their data publicly shared more than losing it all. Whatever the case, it is dangerous to let Gooolag run on the network. Note that deleting Gooolag Ransomware beforehand is likely to negate the recovery process with cybercriminals. This is why the decision on whether to deal with ransomware developers or not lies solely on your shoulders. Nobody can guarantee third-party decryption of Gooolag ciphers at this point time. The only, yet important action to do is remove Gooolag Ransomware from your computer. Instructions on how to do it correctly can be found in our tutorial below.

How Gooolag Ransomware infected your computer

The number of distribution methods used by cybercriminals to deliver ransomware-like infections is abundant enough. The most popular are considered to be trojans, fake software updaters, P2P (peer-to-peer) networks (eMule, torrents, etc.), fake download sources (free file hosting websites), and spam emails bundled with malicious attachments. Trojans are used to open the gates for other malware infections. They are disguised as genuine software updates or program installers, which end up being a ruse. P2P networks and other shady download sources present malware as legitimate software and deceive users into downloading it. E-mail spam usually incorporates infectious attachments of various formats (e.g. PDF, Word documents, EXE, or JavaScript files). If you dare click on one of these files, you are likely to open the door for ransomware into your system. This is why attentiveness and self-awareness should be prioritized to avoid catching infections whilst surfing the web. Below, you will find a list of essential advice on how to protect your system against such threats in the future.
