Phishing is a form of social engineering attack, in which the criminal impersonates a trustworthy entity while requesting sensitive information of the victim.

Ransomware is malware that can lock a device or encrypt its contents in order to extort money from the owner. In return, operators of the malicious code promise – of course, without any guarantees – to restore access to the affected machine or data.


Malware is a combination of two words – "malicious" and "software". This umbrella term describes any form of malicious code, regardless of the way it afflicts victims, how it behaves or what damage it causes.

What is spam?

Spam is any form of unrequested communication sent in bulk (Unsolicited Bulk Email, or UBE). Its most frequent form is a commercial email sent to a large number of addresses (Unsolicited Commercial Email, or UCE), but “spamming” is also possible via instant messages, texts (SMS), social media or even voicemail. Sending spam is illegal in most jurisdictions.

Identity theft

Identity theft is a crime in which an attacker uses fraud or deception to obtain personal or sensitive information from a victim and misuses it to act in the victim’s name. Usually, perpetrators of such crimes are motivated by their own economic gain.
