In a world awash in high-tech security tools like passkeys and quantum-safe algorithms, it’s refreshing to see the old-fashioned canary trap making a comeback.

The Canadian province of Alberta recently used this tool to identify a leak from its electoral list database, which contains personal information on millions of citizens. The trap worked by adding unique, fake entries that would appear in any leaked version of the document. When the separatist group, The Centurion Project, was found using the data, these canary traps revealed the source.

The use of such simple yet effective security measures highlights how even traditional methods can still outsmart modern hackers and leakers. This case shows that in an era of complex encryption, sometimes a good old-fashioned approach is all you need.

Despite the clear evidence from the fake entries, exactly how the data passed from the Republican Party to The Centurion Project remains unclear, but Elections Alberta was swift to investigate and take action. Both parties publicly pledged to respect the law, with The Centurion Project taking down its online tool as a result.

The case of Canada's canary traps serves as a reminder that even in today’s digital age, simple and effective security measures still have their place – no matter how old they may be.
