One of our researchers received what appears to be a “management coaching” invoice scam targeting 🇩🇪 German-speaking victims. Here’s an image of the email regarding the “unpaid” invoice (also attached). Several details immediately raised red flags:
🚩 Strange ChatGPT-esque intro: "dear sir/madam [first name]"
🚩 The email thread references messages from Friday, July 30, 2025, but July 30, 2025, was actually a Wednesday (citing a past deadline also adds urgency)
🚩 The invoice mentions a 🇩🇪 German company, yet the bank details are in the UK 🇬🇧
🚩 The sender claims to represent Cloud9 Adv Ltd, which does exist — but was only established in September last year: https://submit.spamhaus.org
This is a reminder that invoice scams often rely on small inconsistencies that are easy to miss, especially when messages look professional and urgent.
🔍 Always verify before paying.
