Ransomware attacks – 5 steps to keep your data safe
Ransomware – digital extortion
Ransomware is a blend of two English words for ransom and software. Ransomware is malicious programs that can attack computers as well as tablets and smartphones. The principle of their operation is as simple as it is dangerously effective – installed on a hard drive, they block access to data stored on the device in various ways.
Such programs can completely block access to the content of the device (screen-locker), prevent access to files on the device and in the cloud (crypto-ransomware) or encrypt the entire disk (disk-encryptor).
Contrary to appearances, the purpose of such an attack is not to steal data in itself – cybercriminals demand a ransom to unblock access to data.
According to the Sophos report “State of Ransomware 2021”, ransomware costs an average of PLN 1.5 million for a Polish company targeted by an effective attack. The conducted analyzes reveal estimated losses in the order of PLN 50-254 thousand. PLN in 46% of Polish medium and large enterprises. It is worth mentioning that these costs are related not only to the ransom amount itself, but also business downtime, operating costs, lost profits and sometimes penalties imposed by contractors.
