“Many of the reported cases were attempted attacks, rather than successful attacks,” it said in its latest report.
The NCSC added that it assumed the real number of attacks was “substantially” bigger as there is no reporting obligation in Switzerland.
In its semi-annual report published on Thursday, most reported cases concerned different types of fraud, notably emails supposedly sent by law enforcement agencies.
Other forms of fraud include payments, investment and classified ads.
In the period under review, the number of attacks with encryption Trojans, so-called ransomware also increased, often involving double extortion to threaten the victims.
Alleged parcel notifications or delivery problems have also been used in many cases of phishing during the Covid-19 pandemic, the NCSC said.
The report points out that perpetrators often send text messages or emails to their victims.
