The majority of incidents involved PCs or servers being hacked.
A number of cyber criminals also chose to focus on so-called "ransomware" attacks, i.e. they gained access to sensitive data, encrypted it, and demanded a ransom in return for decrypting the data sets. Some major companies based in Luxembourg fell victim to this sort of attack.
Other forms of cybercrimes include phishing attacks, or the so-called "CEO fraud", also known as "Business email compromise".
In her reply to a parliamentary question by MPs Mars di Bartolomeo and Dan Biancalana from the Luxembourg Socialist Workers' Party (LSAP), Minister of Justice Sam Tanson stated that these types of crimes have occurred with increasing frequency, a phenomenon which can most likely be attributed to the increased use of digital platforms by companies over the course of the pandemic. Tanson also mentioned SKY, a major operation carried out by the Belgian police, which was supported by special units from Luxembourg.
Over the course of this operation, investigators not only managed to decipher a large number of encrypted messages, but also arrested 48 individuals and seized 17 tonnes of cocaine in Belgium.
The Minister stated that this operation could also have legal repercussions in Luxembourg, if Belgian authorities decided to file complaints. However, Tanson added that should this be the case, it would then be necessary to assess whether the provided proof is admissible under the Luxembourgish jurisdiction. So far, the public prosecutor's office has not received such a request from the Belgian authorities.
