What ransomware is and why protection is important

Ransomware is a type of malware that locks a device or encrypts the content on the device and then blackmails the user into paying a ransom to gain access to their content again.

And of course, devices are not just mobile phones and computers, they are also servers and the Internet of Things or Internet of Things (IoT).

Therefore, in case of ransomware infection (and non-existent or non-functional backups), the company loses access to invoices and customers, for example.

This form of attack can temporarily interrupt the company's work or production process. Depending on the business or organization, the ransomware attack is likely to have consequences for its customers, which can eventually lead them to turn to a competitor.

According to ESET, businesses often consider ransomware to be their biggest security problem. However, this is not necessarily because ransomware attacks are more common than other forms of cyberattacks, but because these types of attacks often get a lot of publicity. Thus, even someone who has never experienced a ransomware attack may realize that these types of are a serious threat.

Email remains the most common form of ransomware infection

Ενώ η μόλυνση από ransomware ξεκινά συχνά με ένα κλικ σε έναν ύποπτο σύνδεσμο ή ένα πλαστό τιμολόγιο, η ESET έχει διαπιστώσει ότι το email παραμένει η πιο κοινή μέθοδος διανομής σε μια διαδικασία δύο βημάτων, όπου παραδίδεται πρώτα ένα πρόγραμμα ς, ακολουθούμενο από το ransomware ως δευτερεύουσα μόλυνση.

The need to raise employee safety awareness

It is unclear whether successful ransomware attacks are due to the skill of attackers or the negligence of employees. Some types of ransomware are highly sophisticated, others are not. The risk of ransomware infection is one of the many reasons why companies should focus on training their employees in cybersecurity, so they know, for example, what links not to click and what to do if a security mistake has already been made.

Unequal distribution of investments in security issues

Some companies spend hundreds of thousands or even millions of dollars on various advanced security solutions, but not a few thousand more on a well-trained staff responsible for developing and managing network security measures. Instead, companies often choose to acknowledge that there are security vulnerabilities and make this decision because they do not expect to be attacked by ransomware.

The basic rules to follow

According to ESET, the basic rules you need to follow to avoid data loss are:

• You create often security of your data and keep at least a full backup offline.
• Keep all your software - including operating systems - repaired and up to date.
However, holistic coverage should be the first goal of any comprehensive cyber security strategy. This starts with a reliable and multilevel endpoint protection solution, followed by ongoing maintenance and best security practices.

FOR HISTORY:

In 1989, the first ransomware attack was carried out with the… postman

The first documented case ransomware σημειώθηκε το 1989. Ονομάστηκε AIDS Trojan και διαδόθηκε μέσω χιλιάδων δισκετών που εστάλησαν μέσω ταχυδρομείου. Οι δισκέτες αυτές ανέφεραν ότι περιείχαν μια βάση δεδομένων για το AIDS και τους παράγοντες κινδύνου που σχετίζονται με τη συγκεκριμένη .

In fact, the floppy disks contained malware, which disabled users' access to much of the contents of the hard disk. The AIDS Trojan demanded a ransom (or, as the message called it, "license payment"), $ 189, which was to be sent to a post office box in Panama. Responsible for this ransomware was considered Dr. Joseph Popp.
