Major Failures in RAID Systems

With the popularization of storage systems, better known as storages, many companies have begun to use RAID as a solution to store large amounts of information.

The most common justifications we hear from companies when we ask them why they chose RAID are mainly two: the high level of fault tolerance and the low acquisition and maintenance costs.

However, when equipment of this level fails, the data becomes unitizable and, in most cases, corrupted.

There are 3 general categories of failures that a RAID system is susceptible to, and they are:

  • Hardware failure
  • Human error
  • Software failure

Let’s look separately at each of these reasons, giving examples of the most common accidents to happen, so that your company ensures effective protection.

Hardware Failure

If the disk is badly damaged, it is better to directly extract the necessary data and ignore the rest.

Cloning an entire hard drive unnecessarily can stress the device and considerably increase the time needed for the service.

The most common physical damages that usually require a RAID recovery service are:

  • Natural disaster damage
  • Physical abuse of drive
  • Disk overheating
  • RAID controller failure
  • Write head failure
  • Damaged motor
  • Compromised media surface

Human Mistake

In this case, it is very common for employees who have access to these systems to make some kind of mistake such as those mentioned below.

Another problem related to human intervention is when the RAID is already failing and an inexperienced employee, or one without the proper equipment to operate a RAID, decides to try to recover it on his own.

  • Unintentional deletions
  • Reformatting drives
  • Incorrect replacement of components
  • Files overwritten by mistake
  • Employee sabotage
  • Lost/forgotten password
  • Improper RAID installation

Software Failure

When the problem is only in the logic part, specialized software or reverse engineering is usually used to discover the necessary settings and rebuild the array. In this sense, the most common problems are:

  • Backup failures;
  • Computer viruses and worms, especially ransomware;
  • Corrupted files and data;
  • Damaged folders;
  • Directory and firmware corruption;
  • Partitioning and missing partitions;
  • Configuration and formatting.

Of course, the more protected the company’s RAID system is, the better, because unexpected costs and unavailability of important information for the company’s routine are avoided.

However, we know that no security solution is 100% guaranteed and it is necessary to have a card up your sleeve in case an accident – as mentioned above – happens.

In recent years there has been a significant increase in ransomware attacks aimed at the company, and at RAID systems.

Frequently Asked Questions About Ransomware Recovery

Every day, ransomware attacks get
better and better. After a successful
attack attempt, ransomware quickly
maps the user’s most important files to
begin encryption. Microsoft Office files,
databases, PDFs and design are among
its main targets.

Yes, yet the ransomware is designed not to be identified by the firewall, so it can infiltrate the company’s internal system and disable defenses, move laterally, and alter backup routines.

The user can identify the ransomware action, even if the system cannot identify it, the malware uses the system’s own resources for the encryption process, and may be slow to respond to user requests.

The file extensions are changed, a specific extension is added that mentions the attacker group. Stay tuned for these signs.

Yes, it is possible. But there is a risk that some files will be corrupted. Once you identify the ransomware action on the system, disconnect the device from the internet, this will break the group communication with the malware, some ransomware can continue encryption even without internet access.

You can also initiate antivirus countermeasures to isolate the malware and delete it, if the antivirus has not been disabled by the ransomware.

Stopping the encryption is extremely difficult, the ransomware is designed to disable any system or user countermeasures, decreasing the chances of the process being interrupted.

The attacks usually happen when there is a drop in the flow of users in the system, which happens on weekends and holidays, during the early hours of the morning, making these dates suitable for attacks.

There are numerous encryption algorithms, but the most widely used are RSA [Rivest-Shamir-Adleman]-2048 and AES [Advanced Encryption Standard].

First of all, keep calm, criminals count on the victim’s desperation. Follow these tips:

  • Isolate the affected device – The ransomware can move laterally through the system and reach other devices, so it is important to isolate its field of action.
  • Verify backup – If the backup has not been reached by the ransomware, data can be quickly restored without major problems.
  • Avoid contact with criminals – Criminals use psychological tactics to extort as much money as possible in the shortest possible time, the fact that the victim is emotionally involved with the incident makes him an easy target.
  • Don’t negotiate with the criminals – The group gives no guarantee that the decryption key will be released after the ransom is paid, you have to take only the criminals’ word for it. Besides the payment will fund the group for further attacks.
  • Contact government authorities – The government has agencies that specialize in combating cyber attacks, which will investigate the case.
  • Contact a company that specializes in decrypting Ransomware files – RansomHunter is able to decrypt ransomware files without the need for the decryption key, their solutions are an option to paying the ransom.

After the first contact and sending of the data we will diagnose the files to check the extent of the damage caused by ransomware, with this we can project the duration of the process and provide the budget.

After the client approves the budget, we start the decryption process, for this we have exclusive software that can, with the help of our specialists, reconstruct the data.

After the end of the process we will do a double check so that the client can verify the integrity of the recovered files.

Payment is only made after delivery of the files and validation of the same by the client.
