Cyberattacks are becoming more frequent and varied

(22.05.2024) Cyber threats represent a significant risk for Swiss businesses. In the second half of 2023, the Federal Office for Cybersecurity (OFCS) reported 30,331 cyber incidents, nearly double the cases reported during the same period in 2022 (16,951).

The proportion of reports from the public (88%) compared to those from businesses and authorities (12%) has remained stable. However, phishing cases more than doubled in the second half of 2023 compared to the same period in 2022, increasing from 2,179 to 5,536. The OFCS specifically warns about the dangerous "Chain Phishing" technique, where attackers take over email accounts and send malicious emails to the contacts in the address book. Since recipients recognize and trust the sender, the likelihood of them being deceived and subsequently hacked increases significantly.

Among attacks targeting businesses, attempted fraud is also on the rise, particularly through techniques like "CEO fraud" (253 reports; +63) and "business email compromise" (63 reports; +18). However, ransomware attacks have decreased (42 reports; -12).

The OFCS has also observed the first instances of fraud attempts using artificial intelligence (AI). In sextortion cases, for example, cybercriminals generate images showing the victim in compromising situations to extort money or information. Other hackers impersonate well-known individuals over the phone or lure victims with promises of highly lucrative investments to steal their money.

To stay informed about cyber threats and current protective measures, the OFCS recommends regularly visiting its website, the Swiss Crime Prevention website, and the secure e-banking platform (EBAS) from the Lucerne University of Applied Sciences and Arts (HSLU).
