America warns against targeting educational institutions, "ransomware"

The US Federal Bureau of Investigation (FBI) issued a new warning about a new cyber attack called "ransomware," which this time targets educational institutions in the United States of America and Britain.

The warning included that the threat actors behind the attacks, known as "PYSA", encrypt data on the compromised systems, and also steal information from victims and threaten to leak it, in an attempt to increase their chances of obtaining money.

In these attacks, hackers usually use a technique called "phishing attacks" and remote device access software to reach the target networks, by sending phishing messages that contain links, whose mission is to open a hole in the system and the RDP or remote access protocol for devices, for the first access to The target networks, then they use software tools to access the data and then encrypt it.

Ransomware is a type of virus that hackers use to encrypt users' files, until a ransom is paid.
