What is the exfiltration of data and why should you be careful with it?

Cybercriminals use various tools to create new ways of affecting devices. It doesn’t matter if you have a PC with Windows, macOS or even some Linux distribution such as Ubuntu, since from these operating systems to mobile phones such as Android and iOS, there are numerous viruses that can avoid security.

On previous occasions, Police have warned about the increase in phishing cases They are hitting millions of victims. Therefore, knowing the terms and ways of acting in the face of the different circumstances that can be given is crucial so that they do not become something serious for you, such as exfiltration.

You have surely heard from how dangerous the spyware or ransomware can bethey are usually used to steal your information and carry out extortion with threats of all kinds. In fact, once they manage to do things like Spear Phishing or malicious spam calls, they could access your social media accounts and other platforms.

How does data exfiltration work and what causes it?

Knowing exactly what type of attack you are receiving is of the utmost importance to determine what type of actions to perform in order to eliminate them. In this case, data exfiltration is one of the most common tactics among hackers and is that Condue to steal your data to be transferred between equipment.

This process It is also known as data extrusion or exportbecause the cybercriminals obtain an amount of information with their Malwares or attacks and make an intentional transfer without authorization to pass them from your PC to another “system, network or device”, according to what IBM experts explain.

This data collection is received by the attacker to the aforementioned external sources and hence You can use these to apply ransomwaresteal bank accounts and get your money without realizing or even replacing your identity.

The exfiltration can be carried out in various ways, either by manual and specific methods, or through automation on platforms. Affected victims can be both average users, as large -scale corporations, so you should be very careful.

Some people confuse the concept with data leakage Or data violation, but they are different things. The first is «accidental exposure» when things that you do not want in some way are filtered and the other occurs when there is a «technical security vulnerability» where they take advantage to infiltrate alerts.

Extrusion works as a direct stealthy attack and is intentional, requiring the two mentioned processes, since they are the ones that generate this result. For example, ransomware, phishing and other ways of obtaining confidential information They are not exfiltration until these data are copied and exported to another site.

What to do to prevent the data from being stolen?

Most of the time this happens is because there are computer pirates that create ways of entering the equipment, either through viruses or through phishing. However, specialists claim that it also happens because there are «negligent internal users» that allow neglience or vulnerabilities.

Among some of the actions that facilitate things to hackers is download infected files from unknown sourcesclick on unofficial and malicious web pages or grant the information when filling forms or logging into non -safe sites.

The employees of the big companies are the ones that should be more careful because sometimes they are the direct objectives. For example, in 2022 The cybercounts managed to exfiltrate up to 1 TB of data from Nvidia that put at risk the confidentiality of their Deep Learning project. In 2020, Microsoft and Facebook went through something similar.

While common users and corporations usually Use cybersecurity methodsIBM states that the best protection is «to educate users on recommended practices for distance work, password hygiene, the use of personal devices at work and data storage.»

Then, the best defense barrier is to prevent from the beginning that this happens, being very careful with the information that is put on pages, session on various platforms or access SMS messages and deceptive spam emails. Being aware of all this, makes it less likely to be affected.
