Numerous attacks against individuals, few against businesses
A phenomenon far from being marginal, since the number of false sites jumped by "400% from the first week of confinement". But at a time when teleworking was almost widespread, hackers also opted for another method in order to extract money: "ransomware, these programs that encrypt data on a computer before asking for a ransom for them. recover".
