New Ransomware Strain is Locking Up Bitcoin Mining Rigs in China (zdnet.com) 86

A new strain of ransomware has been observed targeting Bitcoin mining rigs. ZDNet reports: At the time of writing, most of the infections have been reported in China, the country where most of the world's cryptocurrency mining farms are located. Named hAnt, this new ransomware strain was first seen in August of last year, but a new wave of infections has been reported hitting mining farms earlier this month. Most of the infected mining rigs are Antminer S9 and T9 devices, used for Bitcoin mining, but there have also been reports of hAnt infecting Antminer L3 rigs, used for mining Litecoin. In rare instances, Avalon Miner equipment (used for Bitcoin), were also reported as infected, but in much smaller numbers.

    Bitcoin or real money?

    • Bitcoin will be approaching "real" when you can buy the hardware to mine it and pay for the electricity to run it in bitcoin.

      • Back in the days when nobody heard of Bitcoin, I mined a few coins using my GPU...

        As the value of Bitcoin rose a bit, I used my Bitcoin to buy a couple Sapphire Block Erupters (back when the hashrate for them was respectable). This netted me a few more coins...

        At some point, I cashed out (waaaaaay too early). The results were enough to pay my power bill for a couple months and a shiny new Nexus 7 tablet...

        Does that mean it's real?
  • Wonder if this is an attempt by someone who has control of a significant but non-majority amount of the transaction pool to artificially reduce the pool size to allow them to do a 51% attack? I'm not familiar with that side of Bitcoin or it's mechanisms so not sure if that is viable or even possible.
    • I'd say it government, namely Beijing. They have seen BTC as a direct threat to their banking system and have taken action in the past to minimize the damage they are doing. And now, they decided to take a cloak and dagger approach to dealing with them. No surprise.

      Or the attack launched by some evildoer who is also a a Bitcoin Cash or other AltCoin proponent.

    • Definitely feasible. Other currencies have been hit by 51% attacks and compromised with bogus double-spending transactions. Since China has 51% control of Bitcoin anyway, this could easily allow them to manipulate it by adding more currency or double-spending existing coins. And with 300 gigs of blockchain, few people are going to validate all the way to check for hanky-panky.

    If victims fail to pay the ransom or infect at least 1,000 other devices, the ransom note threatens to turn off the mining rig's fan and its overheat protection, leading to the device's destruction.

    If this happened to one of my devices, the first thing I'd be doing is attaching the fan(s) directly to the power supply. You won't get any fan regulation, and possibly a lot of fan noise, but you won't need to worry about overheating.

    Also, people who write ransomware are callous scum.

  • I'd say Beijing is up to their old tricks to try to eliminate competition to their banking system?

  • And suddenly light bulbs in China got a little brighter.

  • So it's going to be ransomware thugs versus the Bitcoin community of child porn sites, drug traders, basement-dwelling conspiracy theorists - and yes, other ransomware developers who use Bitcoin to get ransom payments without being traced. All the scams in the world collapsing into a black hole as the rest of us applaud.

    • Windows ransomware? What would possess somebody to run a mining rig on Windows? I can only think of disadvantages.

    The fewer of these resistive heaters we have sucking otherwise useful energy and further warming our planet the better.

To be is to program.
