Oops, We Did It Again: How a Simple Hack Exposed Thousands of Emails
The postmark-mcp backdoor is so simple, it’s like a hacker’s version of a whoopee cushion. Organizations handed over the keys without a second thought. The Koi Security report warns of a systemic vulnerability in the MCP ecosystem, where unchecked tools by unknown developers run amok.
Hot Take:
Who knew that a seemingly innocent Paris-themed gift shop could double as a digital Trojan horse? While most of us are trying to forget our high school French, some folks are using it as a cover for cyber sleuthing. It’s like finding out the Eiffel Tower is actually a cellphone tower for hackers. Zut alors!
Key Points:
- The Postmark MCP server was used as a backdoor to access emails and confidential documents.
- The command to reset passwords was sent to a server linked to a marketplace for Paris-themed gifts.
- The developer deleted the malicious package from npm but the attack persists for current users.
- An estimated 300 organizations and between 3,000 to 15,000 emails were affected daily.
- The incident highlights systemic vulnerabilities in the MCP ecosystem due to lack of security models.
