    Communications Backdoor in Chinese Power Inverters

    This is a weird story:

    U.S. energy officials are reassessing the risk posed by Chinese-made devices that play a critical role in renewable energy infrastructure after unexplained communication equipment was found inside some of them, two people familiar with the matter 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.

    Reuters was unable to determine 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.

    The article is short on fact and long on innuendo. Both more details and credible named sources would help a lot here.

    Friday Squid Blogging: Pet Squid Simulation

    From Hackaday.com, this is a neural network simulation of a pet squid.

    Autonomous Behavior:

    • The squid moves autonomously, making decisions based on his current state (hunger, sleepiness, etc.).
    • Implements a vision cone for food detection, simulating realistic foraging behavior.
    • Neural network can make decisions and form associations.
    • Weights are analysed, tweaked and trained by Hebbian learning algorithm.
    • Experiences from short-term and long-term memory can influence decision-making.
    • Squid can create new neurons in response to his environment (Neurogenesis)

    As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.
