Often, when you hear about big corporations being hacked it's because sophisticated cybercriminals exploited tiny holes in the company's computer systems. That is, despite companies like Target having tough security systems in place.
Yet, that's not always the case. In fact, a Mexican fast-food restaurant just left itself open to security hacks.
It involved the $4.1 billion Chipotle Mexican Grill's human resources department. They would respond to job applicants with email addresses that ended with ChipotleHR.com.
However, one job applicant, a cybersecurity expert, responded to one of those addresses. He received an automatic message bounced saying his message was undeliverable.
