• it is an AntiVirus scanner to detect common webhosting threats
• it uses wonderful rules provided by R-fx Networks at https://www.rfxn.com/api/?id=all
• it supports MD5 sum and HEX-style rules from ClamAV
• it is a fast replacement for LMD (meldet a.k.a. maldetect)
• it always downloads fresh rules on start-up (a feature not bug)
• it uses inotify in Linux kernel to monitor given directories for IN_MODIFY, IN_CREATE and IN_MOVED_TO events
• it scans all detected files smaller than 10 MB and recursively adds new children directories to watch

aptitude install mercurial
go get code.google.com/p/go.exp/inotify
go get code.google.com/p/go-charset/charset
go build

Optional flags:

• --cpu 2 (default: 2) set the number of OS threads used for multi-threading
• --delete 1 (default: false) delete detected threats
• --maxsize 10 (default: 10) skip files bigger than given number of MB
• --notify http://localhost/path (default: none) send an HTTP POST notification about each detected threat
• --quarantine /var/quarantine (default: none) move threats to this directory

You can only choose one of delete or quarantine. Deletion takes precedence.

At least one positional argument is required, specify paths to directories to watch.

./gonotifyav /home /tmp /dev/shm

{"Path":"/tmp/c99.txt","Threat":"web.malware.unclassed.155","Owner":"root"}

• Quarantine directory will be created if it doesn't exist.
• Files will be moved into subdirectories with the name of Unix timestamp
• Files moved there will not have their permissions altered so make sure that regular users don't have access to it.
