Old Crypto Vulnerability Hits Major Tech Firms (securityweek.com)

wiredmikey writes: A team of researchers has revived an old crypto vulnerability and determined that it affects the products of several major vendors and a significant number of the world's top websites. The attack/exploit method against a Transport Layer Security (TLS) vulnerability now has a name, a logo and a website. It has been dubbed ROBOT (Return Of Bleichenbacher's Oracle Threat) and, as the name suggests, it's related to an attack method discovered by Daniel Bleichenbacher back in 1998. ROBOT allows an attacker to obtain the RSA key necessary to decrypt TLS traffic under certain conditions. While proof-of-concept (PoC) code will only be made available after affected organizations have had a chance to patch their systems, the researchers have published some additional details. Researchers have made available an online tool that can be used to test public HTTPS servers. An analysis showed that at least 27 of the top 100 Alexa websites, including Facebook and PayPal, were affected.

Compare stuff made 40-50 years ago to what's made today, including some of the stuff that has "planned obsolescence" built in or really shady shit like with video cards(see where nvidia degraded performance on cards when new models come out). My parents are still using the same refrigerator that they bought when they got married in the mid 1970's. Is it inefficient? Yep. Does the damn thing weigh an assload? Yep. But it's also built like a tank and keeps going. Where as the new fridge that they bought to replace it because "it was more efficient" and it failed. In fact it failed so badly and there were so many of them that there was multiple class action lawsuits(see Samsung refrigerators).

    Wireless charging is convenient, and it can extend the life of your phone if you would otherwise run into charging port issues. I switched to wireless charging when my phone complained of a wet charging port, since it bypasses the water detection.

    The power loss is minimal for a device like my phone that doesn't really use that much power. You're much better off worrying about other ways of saving power. Turning off a light when you're not in the room can save a ton more power. Switching just a single bulb to LED saves far more power. Consider a smart powerstrip that kills power to auxiliary devices when you turn your TV off (sound bar, DVD player, cable box, Roku stick adapter, etc.).

    There are tons of ways to be more efficient. Don't harass someone for ignoring one minor inefficiency in favor of convenience.

    To add to this, there is actually a way for wireless charging to be MORE efficient. The USB port on my Galaxy S5 is wearing out. The phone supports optional wireless charging. A buddy of mine gave me a charging pad for free, and all I needed was the accessory to sit inside the battery compartment of the phone. Now I can continue to use the phone without the worry or need to replace it just because the wired charging port is going bad on it.

    From the OP:
    "ROBOT allows an attacker to obtain the RSA key necessary to decrypt TLS traffic under certain conditions."

    As far as I can tell from reading the attack, this is not true. The attack lets you use the server as an oracle, that is, you can exploit the protocol to trick the server into signing arbitrary data with the server's private RSA key. I think this could be leveraged to mount a MITM attack, but it could not be used to recover the private RSA key. If the RSA private key was recoverable from a flaw in the TLS protocol, that would be a much bigger finding.
