The U.S. has found Trojan horse communication devices in Chinese-made solar power inverters.
Inverters are used to change DC power from solar panels/battery racks, into AC power for use to power homes. In some solar setups, the Inverters also connect to the power grid to "sell-back" energy to the local electric company.
These Trojan Horse devices can be turned on and controlled remotely and can be used to destabilize public energy grids, potentially leading to massive blackouts like the recent one in Spain.
More as I get it . . . .
UPDATE 5:45 PM EDT --
I had to remove the schematic I originally posted with this story solely for reference purposes, because people in the User Comments area started naming a specific brand and model based upon the schematic.
I did NOT report that particular brand as being affected by the Trojan Horse. In fact, I have not yet reported ANY particular brand affected by the Trojan Horse.
But now, since the Users are naming specific names, I had to take the image down because that particular brand is made outside of China and is NOT implicated AT ALL in the trojan horse, and I don't want to smear or defame an innocent company.
So when I get a schematic -- for reference purposes -- that nobody can attribute a brand name to -- I will put a different image up.
UPDATE 7:09 PM EDT --
Rogue communication devices not listed in product documents have been found in some Chinese solar power inverters by U.S experts who strip down equipment hooked up to grids to check for security issues, the two people said.
Over the past nine months, undocumented communication devices, including cellular radios, have also been found in some batteries from multiple Chinese suppliers, one of them said.
At this time, no one is able to say how many solar power inverters and batteries they have looked at.
The rogue components provide additional, undocumented communication channels that could allow firewalls to be circumvented remotely, with potentially catastrophic consequences, the two people said.
Both declined to be named because they did not have permission to speak to the media.
"We know that China believes there is value in placing at least some elements of our core infrastructure at risk of destruction or disruption," said Mike Rogers, a former director of the U.S. National Security Agency. "I think that the Chinese are, in part, hoping that the widespread use of inverters limits the options that the West has to deal with the security issue."
