In 2020, computer systems at the U.S. Department of the Interior were compromised by attackers. They used the "evil twin" phishing technique, in which they tricked individuals into connecting to a fake Wi-Fi access point controlled by the attackers. This allowed them to steal credentials and access the department's wireless network. Further investigation revealed that the department did not have a secure wireless network infrastructure, and it had failed to meet its own internal security requirements, such as robust user authentication and regular network testing.
In July 2018, Marian Simulik, the treasurer of the City of Ottawa in Ontario, Canada, received an email purporting to be from the city manager. The email instructed her to wire $128,000 to a supplier in the United States. The city's website was undergoing an overhaul at the time, and the treasurer thought the request was related to that project. She researched the supplier and corresponded with someone she believed to be the city manager via email, and sent the funds to a US bank account. Soon after, Simulik received another request for money from the same scammer. She asked the city manager about it, but they said they were not aware of either request.
Simulik realized she had fallen victim to an email-based scam. In April 2019, KnowBe4 published an article about this incident, warning about the dangers of phishing attacks targeting government officials.The ability of the fraudster to impersonate the city manager and the treasurer's assumption that the request was legitimate due to the website overhaul demonstrates the sophistication of these attacks.
