Gryphon encryption-for-ransom is the ransomware detected by IT security at the last day of July 2017.
The threat deprives the users of computer systems affected of access to their data. The data is not just locked. The malware actually modifies the data structure with a military strong algorithm. The modifications involve private and public key. The public key basically encrypts the files. The crooks definitely have injected this key onto the computer system. It is possible to (try to) intercept it, but there is no use. You need a private key, which, despite related to the public key, cannot be computed from the public key. The math engaged is so strong that even a computation plant like one used in contemporary Bitcoin mining, will not do.
.gryphon ransomware ransom note
The attack is extremely sophisticated in its encryption payload. As regards the introduction, it is pretty simple. Most of the invasions occur as the users open a spam email. Not only the users open the spam, they download and open the attachment. Still, that does not suffice to get infected. The infection installs where the macros executes. The macros is embedded in the attachment. Typically, it is a Word document. If Word is configured to run Macros automatically, opening the compromised document immediately spawns Gryphon ransomware installation. Otherwise – in most of the cases, – the users need to authorize the macros. Needless to say, you shall be very careful with any attachments. Proper verification hardly leaves any room for any ransomware invasions.
The Gryphon trojan targets Windows users. Its distribution coverage, language used in the GUI and the spam emails suggest the English-speaking audience makes a priority target. The malware survives and executes its encryption-for-ransom payload even in the latest implementations of Windows OS.
The ransomware is a known threat. A number of antivirus tools detect the trojan under specific names e.g. Ransom:Win32/Genasom, Ransom_GRYPHON.A.
Gryphon is not a brand new malware. Its operation is pretty similar to that of such threats as Storm ransomware and other types around. The rogue scrambles data with a case-specific version of AES-256 algorithm. The encryption covers most of the common data formats, as well as reaches any memory available for the host system. Few exceptions only ensure the system remains functional so that the users read the ransom note dropped by the invader. This note is typically contained in HELP.txt. The demands and conditions are quite common: further negotiations by email specified, free decryption for 3 files at user’s choice, ransom payable in bitcoins.
Files encrypted by .gryphon malware
Even if you pay as prompted, there are no guarantees. Gryphon encryption software too often fails. Besides, the crooks may send no decryptor, even though they receive the amount agreed.
True, in some circumstances the data values too much. The users rush headlong to any measures. Paying the ransom is a far cry from a trusted and fair solution. IT security supplies some workarounds that the victims are invited at least to give a try. These include the Gryphon ransomware removal, which is a must. Whether the recovery or paid decryption takes place, you need to get rid of Gryphon trojan. Otherwise, the same ransomware may simply repeat its encryption payload.
Automated cleanup to remove Gryphon virus
Infection vector for ransomware typically features a trojan. The one in question definitely subscribes to that routine. The trojan drops its body into target computer and proceeds with disabling the detecting functionality of any security solution installed. The antivirus is thus unable to spot introduction of virus from the remote server.
The ransomware invasion is indicative of its dropper residing in the computer memory. It also hints at other invasions. The PC can hardly be considered properly protected due to the impacts of the above trojan.
Ultimate option implies a total formatting for any drives of your PC. That is not an option for many users, for it destroys all the data hosted by the machine. The best solution to pick would be in-depth system examination with a reliable security suite.
The trojan that has installed Gryphon ransomware , unless removed, is to trigger its installation campaign as soon as a new strain of ransomware is available. Thereby, it is critical to kill it as soon as possible.
The technique successfully overcomes malicious software, including any ransoming threats. It deploys a reputable security suite that offers not a single chance for malicious components to avoid detection and extermination. The software is incredibly user-friendly and operates on a single-click basic.
It is good to note the removal of Gryphon ransomware does not recover the data affected. However, the virus is subject to compulsory extermination or else is going to introduce related infections into the machine.
1. Click the button to download the stub installer and go through several setup dialogs. Once the tool is up and running, click Start Computer Scan
2. Wait until the cleaner checks the PC for Gryphon ransomware malicious code. As soon as the scan is completed, the report will list all malware objects spotted in the system. Make sure the entries for detected infections are checked, and select the Fix Threats feature. This will result in malware removal and system remediation, so you should now be good to go.
Restore the encrypted files
Gryphon encryption is a sophisticated data modification. There is no simple and single solution to cover all the cases. Transferring the ransom as demanded by the crooks is not the way either.Kindly apply the methods outlined below as they have been carefully developed to provide a recovery help for the most severe cases of encrypting assaults.
Data recovery with automatic software
Good news is that the virus actually deals with copies of the files. The originals have been deleted. The removed data still can be restored by virtue of such tools as Data Recovery Pro.
Shadow Volume Copies
As Windows creates backups at given periods of time, a victim is advised to address relevant restore points. Unfortunately, the method cannot apply unless the System Restore had been enabled prior to the invasion. Please also note the recovery returns files as saved before the time associated with the restore point addressed.
- Previous Versions dialog to target individual files
One can open Properties for any file. The menu has a tab called Previous Versions. It indicates versions of a file that have been backed up.
To make use of the feature, right-click an affected file and choose Properties in the drop-down list. Proceed with clicking the above-mentioned tab. You can opt between the Copy or Restore procedures, the former enabling to copy the item into the location specified by the user.
Backups and removing remaining traces of Gryphon virus
Prevention is the best cure. If you stick to making regular reserve copies of your data and store those outside your operating system, the impacts by the ransomware are very limited. However, prior to copying the data from backups into the system hit by Gryphon ransomware, make sure the removal of this virus has completed.
Your manual removal attempts may kill the ransomware in general. In most of the cases, some remnants manage to survive and are still capable of causing a significant damage. Please apply a reliable anti-malware scanner to detect and remove, if applicable, any remaining infections.
