Roughly 16% of Swiss federal politicians had their official government email leaked on the dark web. This puts them at risk of phishing attacks or blackmail.
In the latest installment of our investigation into politicians’ cybersecurity practices, we found the official government email addresses of 44 Swiss politicians for sale on the dark web, roughly 16% of the 277 emails we searched. Constella Intelligence(new window) helped us compile this information.
Sharp-eyed readers might wonder why we searched for 277 email addresses if there are only 253 politicians between the Council of States, Federal Council, and National Council. The explanation is some politicians publicly share another email address along with their official government one. In these cases, we searched for both.
Since these email addresses are all publicly available, it’s not an issue that they’re on the dark web. However, it is an issue that they appear in data breaches, meaning Swiss politicians violated cybersecurity best practices and used their official emails to create accounts with services like Dropbox, LinkedIn, and Adobe, although there is evidence some Swiss politicians used their government email address to sign up for adult and dating platforms.
We’re not sharing identifying information for obvious reasons, and we notified every affected politician before we published this article.
Swiss politicians performed roughly as well as their European colleagues, having few fewer elected officials with exposed information than the UK (68%), the European Parliament (41%), and France (18%), and only slightly more than Italy (15%).
It should be noted that even a single compromised account could have significant ramifications on national security. And this isn’t a hypothetical. The Swiss government is actively being targeted on a regular basis. In 2025, hackers used DDoS attacks(new window) to knock the Swiss Federal Administration’s telephones, websites, and services offline. In 2024, Switzerland’s National Cyber Security Center published a report stating the Play ransomware group stole 65,000 government documents(new window) containing classified information from a government provider.
