Trojan win32 mamson a ac что это

Issue description

Attempting to install matlab-zmq, which requires libzmq. Downloaded libzmq-v142-x64-4_3_4.zip to match installed VS Studio environment. System waned of ‘Trojan:Win32/Mamson.A!ac’ trojan in ‘benchmark_radix_tree.exe’ while unzipping archive. To eliminate the possibility of a false positive, I downloaded the same zip on Linux and decompressed it. I then submitted the same binary to multiple online malware scanners, and and received positive hits from multiple sites.

While I did not test every binary release, I did test v141, v120, and mingw64 of 4.3.4, none of which triggered an alert.

Environment

• libzmq version (commit hash if unreleased): 4.3.4
• OS: Windows 10 Enterprise

Minimal test code / Steps to reproduce the issue

1. Download libzmq-v142-x64-4_3_4.zip from releases section, and extract archive or pass through other AV product.

What’s the actual result? (include assertion message & call stack if applicable)

Operating system quaranteens ‘benchmark_radix_tree.exe’ by expunging it from zip file and warns of detected malware.

What’s the expected result?

Files are clean and virus free.

Windows Defender was the first to complain. Considering that it might be a false positive, I searched for a web based checker.

I tried several sites that run samples through multiple AV engines. Digging deeper I’ve read that sites like Virustotal will produce some false positives, and that the ratio of positive to negative hits should be considered. In this case Virustotal said 19 out of 68 engines flagged the file. One of the bits of info provided as justification is ‘invalid-rich-pe-linker-version’. There’s post in the forums on Malwarebytes talking about false positives from this cause. A post on Reddit’s /r/Visual Studio suggests that VS2019 quite often produces binaries that false positive. These may be an artifact of the engine used not being up to date with the semantics of newer linkers.

I also tried submitting the binary to Jotti as well. Microsoft Security Intelligence has a submission form for software developers to submit misclassified examples. Perhaps submitting that release will better train Windows Defender.

Trojan:Win32/Mamson.A!ac

I have been mining with nicehash for 3-4 months now on my gaming pc (3090) to try and make back some of the cost. Today, when opening nicehash, I got a windows defender notification saying a trojan was detected. I am on windows 11. Look at attached screenshot for more info. Should I restore the "threat"? I am pretty sure this is just a false positive from WD but am wondering why it hasn't happened in the past. I did not change any WD settings.

If you are having issues with Windows Defender deleting NBminer, please read this post:https://www.reddit.com/r/NiceHash/comments/tp5qvl/regarding_nbminer_issues/

What worries me is that prior to this, NBminer was detected accurately as "Potentially Unwanted Application — Bitcoin miner", which is exactly what it was, so it wasn't a false positive. This time, it's being detected as a remote access trojan. There should be no reason why Nicehash or NBMiner should share functionality with remote access. Sometimes trojans do get compiled into production code from trusted sources.

I'm leaving it disabled for now. Not worth the risk unless it's a dedicated mining rig that you don't use to check emails/log into your wallets etc. Give it a couple days and we'll know for sure whether it was false positive or not.
