Equifax had 'admin' as login and password in Argentina
Found on BBC News on Wednesday, 13 September 2017
"We learned of a potential vulnerability in an internal portal in Argentina which was not in any way connected to the cyber-security event that occurred in the United States last week," an Equifax spokeswoman told the BBC.
"[It] was wide open, protected by perhaps the most easy-to-guess password combination ever: admin/admin," wrote Mr Krebs.
That shows non-existant basic security features which would have prevented this.
