An anonymous reader writes Researchers at Trend Micro have uncovered a gas pump in the United States whose ID has been changed from 'DIESEL' to 'WE_ARE_LEGION' — the call-sign of the Anonymous hacking group. Following up recent revelations regarding the vulnerability of gas pump systems to online attackers, the researchers found 1,515 completely unprotected gas pump monitoring devices via the Shodan device-based search engine. The report notes that the exposed devices are capable of being protected via six-digit pins, but this security measure is not being used. The report concludes: "Our investigation shows that the tampering of an Internet-facing device resulted in a name change. But sooner or later, real world implications will occur, causing possible outages or even worse."
