I saw this on FB a few times, and today someone tried to catch some fish around the forum, luckly the topic was deleted, i hope nobody fell for it



what these people show you is a live miner running say at 15xhash, then they download this .exe file and launch it, go back to the same page and suddenly the hashrate is at 28-30xhash.

they started to be active since the fall of prices, when things started to get really rough for miners , they know many people will be more than willing to boost their hashrate by 2x, when lambo ?

always use your common sense, too good to be true ? scam !

- there is no way you getting 100% improvment on only software level
- running a windows executable file to modify a linux based miner is b.s that you should never trust regardless of the source.

you should also notice that many of those custom firmware have much higher dev fees than they claim,so should you decide to use one, monitor it closely.

stay safe fellow miners.

I replied to the thread you have screenshot before it was deleted. I ran the linked “firmware” through VirusTotal, which alerted to it being a backdoor/trojan.

In this space especially, people need to be extremely cautious about everything they bring into their network environment. Only takes one mistake to have a realllly bad time.

Grin that's great! Smiley

@mikeywith, if you have the video link saved can you do a virustotal on the exe, use the link function in virustotal don't actually download the thing? I'm curious as to whether it's supposed to fiddle with the miner or use some sort of heuristic to find a wallet file that they can send to themselves?

Obviously this is quite a cheap gimmick. Anyone who's done anything with hacking or even certain code changes on the browser side will know how this can be done.

There is a saying, which goes 'there are no free dinners'.
And if something sounds too good to be true, then it most likely is not true.

It's that simple.

I think it's important people should also realise that a virus check has no guarantee to find a virus - so if you do grab some software from somewhere and it passes your virus program check, that doesn't mean it doesn't have a virus.

Virus checkers only check for known viruses, so if someone makes a download and writes a new as yet unknown virus to put in it, it's possible to pass any virus program checks.

Also be aware - related to the above - that there are Windows viruses that do in fact change your pool settings in any miners they can find and point your miners to mining for someone else.

While standard manufacturer S9s so not allow this virus to affect your miners, a program like awesome miner has the standard option to allow such viruses to get into your miners.

This is my fault Kano, I did not know that I had enabled the setting in AM's Antminer API Access option page.

Well no, the problem is that is the default setting in that program, if you wish to change the API access: make make it open to anyone who can connect to the miner.

How do I get good firmware?

Usually the firmware which is provided by the manufacturer is good enough, most of them put out some updated firmware from time to time (some of them disable SSH access like bitmain) but it does not really matter to most people.

the other option is to get an open source firmware like Braiins OS which is pretty good as well.

the real question tho, why do you want to change the firmware that comes with the miner? if it's to save a bit of power, do a bit of tuning then it's understandable, however if you are looking for 100% or 50% more hash rate then you shouldn't be mining in the first place, you should understand that the overall improvements you get from using "another" firmware are very limited, anything that is too good is simply fake.
