McDonald’s Login Credentials Allegedly Leaked in Multi-Country Breach Targeting 300,000 Accounts

• A threat actor named xCapuche1337 claims to have leaked 300,000 McDonald’s login credentials
• The data allegedly includes email addresses and plaintext passwords from users across multiple country-specific domains.
• It appears to originate from regional portals, suggesting a widespread, multi-national exposure 

McDonald's has allegedly fallen victim to a data breach, according to a dark web post by a cybercriminal. While the fast-food giant has yet to confirm or deny the breach, the threat actor asserts that over 300,000 login credentials have been exposed.

The dark web actor, operating under the alias ‘xCapuche1337’ claims to have leaked user credentials from multiple McDonald’s platforms worldwide. The above screenshot shows a listing on a dark web leak forum by xCapuche1337, advertising access to 300,000 McDonald’s user credentials. 

The URLs reveal login portals for country-specific McDonald’s websites, suggesting the breach spans multiple regions.

“The dataset includes email addresses and plaintext passwords for user accounts across multiple McDonald’s country sites,” highlighted HackManac, a cybercrime monitoring platform. 

The dataset is reportedly associated with accounts across various country-specific McDonald’s sites. 

If verified, the leak exposes McDonald’s users to risks such as credential stuffing, account takeover, and potential phishing campaigns. Because the leaked data allegedly includes plaintext passwords, users may also be vulnerable on other platforms if they reuse the same credentials.

Concerned users should immediately:

• Reset their McDonald’s account passwords, especially if reused elsewhere
• Enable two-factor authentication (2FA) wherever available
• Check if their credentials appear in the breach using tools like HackCheck or Have I Been Pwned
• Monitor for suspicious account activity, including unexpected password resets or login attempts from unfamiliar locations

As of this publication, McDonald’s has not issued an official statement regarding the alleged breach. TechNadu has reached out to the company for clarification on the authenticity of the leaked data and the scope of the potential compromise. This article will be updated if or when McDonald’s responds.
