Ransomware e Acronis Active Protection Giacomo Lanzi

Acronis Active Protection: defense against ransomware

Acronis Active Protection is an advanced anti-ransomware technology. It actively protects all the data on your systems: documents, data of all kinds and Acronis backup files. It is a technology available for Windows and Mac OS X operating systems and protects against the latest ransomware actions such as Petya, WannaCry, Locky and Osiris.

What is Ransomware?

Ransomware is a particularly painful type of malware. Malware is “hostile or intrusive software” illegally introduced into your system for malicious reasons. When ransomware infects the system, it blocks access to data. Whoever introduced the malware will then make a cash request to unlock the data. In short, the mechanism is that of redemption.

To defend against this type of attack, it is necessary to constantly monitor the activities that take place in the system.

Find the patterns

Acronis Active Protection constantly observes the patterns in how files and data are changed. A set of behaviors can be typical and expected. Another may report a suspicious process that aims to initiate hostile actions against the data.

Acronis’ approach is as follows: examine these actions and compare them with patterns of malicious behavior. This approach can be exceptionally powerful in identifying ransomware attacks, even from variants that have not yet been reported. The latest version of Acronis Active Protection adds additional behavioral patterns to improve ransomware detection.

Acronis has invested heavily in a new dedicated machine learning infrastructure used for telemetry and data processing. The first step in the process is a stack trace analysis. It is possible to detect malicious code by using the stack trace analysis of a process based on the machine learning approach.

The data to be studied and analyzed are the stack trace dumps / frames which are sent as input to the Acronis Machine Learning module. The output of the analysis will be the verdict: clean or infected data. This approach takes active protection to a new level, especially when it comes to threats never used before (called Zero Day).

The system does not require signatures of any kind, but rather creates a model of what is acceptable and what is not. In this way, when hackers will find a new vulnerability or a new approach to infiltrate the system, they will hardly be able to pass this behavior check made thanks to the models applied by Acronis.

Defense against advanced threats

Acronis Active Protection can detect very sophisticated ransomware threats that usually appear as legitimate operations. The detection of attacks takes place thanks to the application of advanced heuristics and machine learning, but not only.

In fact, special mathematical approaches are also adopted to calculate the entropy of the files, in order to understand if the file has been modified even if the header remains the same. Many anti-ransomware solutions, on the other hand, only act based on file headers.

One way that criminals could choose to compromise files would be to attack the backup software itself to corrupt the backup files it creates. To protect against this, Acronis has implemented a robust self-defense mechanism that will not allow criminals to interrupt the work of the Acronis application or the contents of the backup files. In addition, Acronis Active Protection checks the Master Boot Record of Windows-based computers. Hence, it will not allow illegitimate changes to be made to prevent the computer from starting.

How it intervenes

If the ransomware attack starts encrypting files, Acronis quickly detects and stops this process. Since Acronis is a backup solution, any data that was exposed and encrypted before the process was stopped can be recovered from a variety of sources. This is remarkable, considering that not only can anti-ransomware solutions commonly fail to terminate an attack once it has begun, they also have no way of recovering files encrypted by the attack.

Acronis Active Protection detects and deflects attacks and restores files of any size.

The methodologies detect and deflect attacks and advanced file recovery. These protection approaches are not only leading the way against criminals, but they are more innovative and advanced than any other anti-ransomware methodology available.

The Acronis solution is able to identify:

– Hackers trying to infect or compromise local or cloud backups
– Reduced attacks and usually more difficult to detect (for example, changing only a small portion of a document or a photo stored deep in the hard disk)
– Attackers who come up with creative new ways to attempt maliciously manipulating files

Conclusions

The application of artificial intelligence in the field of cyber security has made giant strides in defense possible and is making life extremely complicated for hackers. The search for innovative solutions is now oriented towards the implementation of machine learning to try to capture malicious behavior rather than the attacks themselves. Acronis Active Protection does this and does it effectively, offering complete and efficient protection from ransomware attacks.

The threats do not end once the security of your systems and perimeter has been verified, you must adopt constant defense and verification solutions to ensure your data in the best possible way.
