Buggy 'smart meters' open door to power-grid botnet
"New electricity meters being rolled out to millions of homes and businesses are riddled with security bugs that could bring down the power grid, according to a security researcher who plans to demonstrate several attacks at a security conference next month.
The so-called smart meters for the first time provide two-way communications between electricity users and the power plants that serve them. Prodded by billions of dollars from President Obama's economic stimulus package, utilities in Seattle, Houston, Miami, and elsewhere are racing to install them as part of a plan to make the power grid more efficient. Their counterparts throughout Europe are also spending heavily on the new technology.
There's just one problem: The newfangled meters needed to make the smart grid work are built on buggy software that's easily hacked, said Mike Davis, a senior security consultant for IOActive. The vast majority of them use no encryption and ask for no authentication before carrying out sensitive functions such as running software updates and severing customers from the power grid. The vulnerabilities, he said, are ripe for abuse. (...)"
Em Portugal a assim chamada telecontagem já existe em algumas localidades (p.ex. procurar telecontagem no site da EDP).
