How can file can be corrupted by encryption ?
Data can be lost in files for many reasons, ranging from human error to cyber-attacks to operating system crashes. SosRansomware has the experience to deal with any system and any data loss situation.
Common causes of data loss on files :
Hardware Issues:
- Hard drive failures: Physical damage to the hard drive, such as bad sectors or head crashes, can lead to file corruption.
- Power surges or outages: Sudden power fluctuations can disrupt file operations and cause corruption.
- Faulty memory: Damaged RAM can lead to incorrect data transfer and file corruption.
Software Issues:
- Software bugs or glitches: Errors in software can cause files to be written incorrectly or read incorrectly.
- Incompatible software: Using software that is not compatible with your operating system or other software can lead to file corruption.
- Virus or malware attacks: Malicious software can corrupt files by deleting, modifying, or encrypting them.
User Error:
- Accidental deletion or modification of files: Mistakes made by users can lead to file corruption.
- Improper file transfer or storage: Incorrectly transferring or storing files can cause corruption.
Other Factors:- Network issues: Problems with network connections can cause file corruption during transfers.
- File system errors: Errors in the file system can lead to file corruption.
- Environmental factors: Extreme temperatures, humidity, or dust can damage hardware and cause file corruption.
Tips for recovering files
Contact us Don't hesitate to send us a sample file for a quick diagnosis.
Compress before download You can use software like 7zip to compress the file. The advantage is twofold: it reduces the file size, and you can be sure that the transfer went smoothly and that the file is identical to yours.
Always work with a backup copy or image file, Never work on the original files. Make copies.
List the backups you have if you have a file that's a month, 6 months or even 2 years old, that could be useful.
Look for error messages Error messages can provide clues about the cause of the corruption Please indicate in the form.
Our R&D unit and corrupted files
File corruption presents an additional set of challenges for recovering lost data. These challenges are not solved by commercial or free data recovery software utilities.
We’ve developed a proprietary RepairX tool that enables recovery from corrupted files, when commercially available software is ineffective.

Success story
Why can SOS Ransomware help you?
Microsoft Access File crypted by a ransomware
A Paris-based software publisher contacts us on Tuesday May 7th at 9pm.
Il héberge des données clients et veut à tout pris que tout redémarre le vendredi.
Wednesday and Thursday are public holidays: he decides to take the on-call formula.
Following a problem configuring the size of a virtual disk under Vmware, his system no longer boots and he no longer has access to the datastores.
He had just increased the size of the virtual disk from 1 to 1.5 TB.
We receive 8 x 1TB Dell SSD NVME (U2 connector) disks from hosting provider Scalway. The server is a DELL R640 server rack on which a Vmware ESXI 7.2 server is installed.
They have no backup!
Within 48 hours, we found all the virtual machines that were stored in the datastores and the SQL 2019 databases of over 300 GB. The sparse files are integrated into the original vbk to obtain the data from the last backup.

With over 250+ ransomware cases, we have adapted our tools and processes to achieve success.
Since 2019, we have been developing our tools specifically for recovering data from corrupted files.
Our software has been rewritten to process corrupted files even faster.
We offer to prove our expertise with a free analysis of a corrupt file of your choice. Just send it to us.

You can upload your file on a platform with zip or rar with a password The advantage is that there's no need to physically transport the file, so there are logistical savings and no risk of damage in transit. There are no customs issues to consider... Your server can remain online if services are running on it.
