Cyber Security Month 2026: Oversharing – Share with care
Bern, 01.10.2026 — Whether on social media, in our daily working lives or when using artificial intelligence, every day we share information and leave digital traces behind: often more traces than we realise. For criminals, this information, when published on the internet, can be invaluable. The National Cyber Security Centre (NCSC) is dedicating this year’s Cyber Security Month to the topic of “Oversharing – Share with care”.
A single photograph, a telephone number or a name may seem harmless at first. However, when various items of this kind of information are combined, it can paint a surprisingly detailed picture of a person. For criminals, this information, when published on the internet, can be invaluable. When combined, these forms of data can be used to carry out personalised phishing, identity theft, fraud or targeted manipulation. Over the next four weeks, the NCSC will be explaining where oversharing begins, what risks are involved, and how we can be more mindful about how we handle our personal data.
Intergenerational dialogue
As in the previous year, the campaign for Cyber Security Month in October was developed in collaboration with Netpathie. In cross-generational workshops young people and older adults are set to explore the issue of oversharing. Using specific examples, they will see how quickly a personal profile can be created from individual pieces of information and how this can be exploited for criminal purposes. Together, they will develop strategies for sharing information more responsibly and for identifying suspicious situations early on.
Your daily working life: using AI safely
In addition to the intergenerational dialogue, the NCSC is placing a further focus this year on oversharing in the context of artificial intelligence. Artificial intelligence offers countless opportunities in our everyday working lives, for example when writing emails, translating texts or analysing data. However, it gives rise to new risks when personal, confidential or business information is entered into AI tools without due care. In collaboration with the Federal Data Protection and Information Commissioner, the NCSC is therefore examining the use of AI in our everyday working lives and the associated cyber security risks. The key question is: what information can I safely entrust to an AI tool – and what information is it better to keep to myself.
