New Destructive Malware Intentionally Bricks IoT Devices (bleepingcomputer.com)

An anonymous reader writes: "A new malware strain called BrickerBot is intentionally bricking Internet of Things (IoT) devices around the world by corrupting their flash storage capability and reconfiguring kernel parameters. The malware spreads by launching brute-force attacks on IoT (BusyBox-based) devices with open Telnet ports. After BrickerBot attacks, device owners often have to reinstall the device's firmware, or in some cases, replace the device entirely. Attacks started on March 20, and two versions have been seen. One malware strain launches attacks from hijacked Ubiquiti devices, while the second, more advanced, is hidden behind Tor exit nodes. Several security researchers believe this is the work of an internet vigilante fed up with the amount of insecure IoT devices connected to the internet and used for DDoS attacks. "Wow. That's pretty nasty," said Cybereason security researcher Amit Serper after Bleeping Computer showed him Radware's security alert. "They're just bricking it for the sake of bricking it. [They're] deliberately destroying the device."

    These devices were already broken. Now they are non-functional as well.

    Better than the two women that got killed because their insecure garage door opener let the maniac in.

    I can break into your house because it's not secure enough. Is that OK too?

    If the house has already been taken over by a criminal gang, it's a different matter. That's a better analogy with a lot of these insecure IoT devices. They aren't just sitting there innocently; if they're vulnerable to being shut down by this malware, they're also vulnerable to being taken over by botnets. This is not just a theoretical worry; some of the big recent DDOS attacks have been by IoT device botnets.

  6. Nasty?! Isn't this better for everyone? by monkeyzoo · · Score: 4, Insightful

    The security researcher calls this nasty?! It's genius!

    It's certainly vigilante. But given the societal harm being caused by shoddy IOT devices, bricking them is quite arguably noble. Also, this could be good for the affected users too. Would you rather have your cheap IOT device fail and realize something is wrong with it or have it become an entry point for stealing critical data from your network or infecting your important devices with ransomware?

    At least if your device breaks, you realize something is wrong with it and can complain to the manufacturer for a refund instead of it spying on you and/or serving as a node in a criminal's botnet.

    Not to mention that in the long run, the impact of this would likley be that companies face immediate PR blowback that kills sales when they release shoddy devices. They will quickly learn that to make any money they need to pay attention to implementing reasonable security precautions.

    Carry on soldier!
