Decrypt and remove GandCrab 5.2 ransomware

The contamination with the ransom of GandCrab 5.2 is a serious problem, leading to denial of access to data and terrible blackmail.

Most people who are more or less familiar with computer security have heard of ransom programs. This despicable phenomenon has been in the news for years. However, few people are aware of the real consequences of such an attack, unless they have been hit at least once. Valuable digital memories in the form of photos and videos, but also valuable work files and tons of other personal information – all of this is suddenly no longer available and no one can restore it. The general reaction is therefore a mixture of panic, despair and outright anger.

This is the thrust of GandCrab 5.2. This variant of the ransom demand most discussed today appeared a few days after the release of a free decoder commissioned by researchers. Here’s the problem: The recovery tool hacks GandCrab mods up to version 5.1, but it is totally ineffective in deciphering this output due to some urgent bug fixes by fraudsters. It is the cryptographic implementation that underwent the most tangible changes in the latest version.

Most of the characteristics of GandCrab 5.2 show close similarities with the peculiarities of its predecessors or do not differ at all. It always uses a random extension for the host files, generating the string uniquely for each infected computer. The length of this victim identification is variable and varies between 5 and 10 characters. When any file is encrypted, it takes a form similar to this one: Shark.png.iblkoqnt – Write down the victim-specific extension after the original filename. Another important element of the attack is the ransom demand, which is created on the desktop and in the folders with the captured files. The name consists of the above file extension in capital letters plus the words DECRYPT or MANUAL (e.g. IBLKOQNT-DECRYPT.txt). The different structures of the title and file extensions of this document, which can occur in nature, are explained by the fact that GandCrab 5.2 is distributed by different groups of cyber criminals under the auspices of the same RaaS (Ransomware as a Service).

In addition to these signs of compromise, the attack comes with the replacement of the desktop background. Infection builds a new one, which says encoded by GandCrab 5.2. Dear [username], your files are protected by our software. You have to buy a decryptor for recovery. For the following steps, read the [VICTIM ID]-DECRYPT.txt file located in each encrypted folder. In fact, that’s exactly what she says. The user is invited to visit his personal decryption page in the Tor-browser. The resource requirements state the exact amount of the fee, which can vary from USD 600 to USD 1,200. There is a payment term of 7 days. After the deadline, the ransom will be doubled.

GandCrab 5.2 mainly does rounds without malicious spam. Target users receive malicious Word documents disguised as a request for information, an invoice, a job offer, or any other curious file. When a nested object is opened, the receiver is asked to activate macros, otherwise they cannot see the content. It’s a trap that triggers a backstage ransom scenario. This specific option also extends to hacked remote desktop services and operating kits that use unprecedented software to unload loads. After all, the consequences are just as serious, regardless of the method of distribution. To understand them, follow the recommendations below and take extra precautions to avoid such raids in the future.

We now know that not everything that is removed from the computer disappears completely and can be removed from memory using certain techniques. Recovery applications can do this, so this method is definitely worth a try.

Option 3: Shadow Copies
The Windows operating system includes a technology called Volume Snapshot Service (VSS) that allows files or volumes to be backed up automatically. One of the most important conditions for this is the inclusion of the system recovery function. If it was active, certain data segments can be successfully restored.

You can perform this task using previous versions of the functions integrated in the operating system or using special applications that perform this task automatically.
