Free usc trojans software for mac

Trojan Wrangler 1.0 is a simple to use, yet sophisticated utility which scans media files for the resources that Mac OS X uses to locate code. There's some concern that Trojan horse programs can be hidden in certain media files (MP3, AAC, GIF, JPEG). There are plenty of other ways to disguise programs as other sorts of files so unsuspecting users can be tricked into running them, but if this particular issue is a concern Trojan Wrangler will let you scan any downloaded media files for hidden code.

Hardscan is a local netstat replacement that scans for open ports the hard way: by binding to each of them and attempting to handshake with itself.
Hardscan is meant to be useful in a situation where you may have been rooted, rendering the output of netstat and other security tools untrustworthy.
If the program is unable to handshake with itself, for whatever reason (perhaps something intercepted the handshake, perhaps something was already running on that port, etc) it is an indicator that tcp or udp port being checked is already in use.
Although this could be a trojan, virus, or hacker connection, it is also quite possible that it is a legitimate connection.
As the "Ephemeral" high-numbered ports are scanned as well, there is a chance that any outgoing activity (for instance browsing the web while the scan is running) will be picked up.
Of particular note in this program is "--fast" mode. In this state, the scanner does not attempt to handshake with itself, and thusly is not detecting as rigorously.
In theory the OS could be lying to the scanner and simply saying that the socket was opened succesfully, but in practice most trojans are not going to be that sophisticated. Fast mode trades off this verification in order to run much, much, much faster.

chkrootkit is a free and open source security tool to locally check for signs of a rootkit.
chkrootkit has been tested on: Mac OS X, Linux 2.0.x, 2.2.x, 2.4.x and 2.6.x, FreeBSD 2.2.x, 3.x, 4.x and 5.x, NetBSD 1.6.x, OpenBSD 2.x, 3.x and 4.x., Solaris 2.5.1, 2.6, 8.0 and 9.0, HP-UX 11, Tru64, and BSDI.
chkrootkit comes with the following tools:
- chkrootkit: shell script that checks system binaries for rootkit modification.
- ifpromisc.c: checks if the interface is in promiscuous mode.
- chklastlog.c: checks for lastlog deletions.
- chkwtmp.c: checks for wtmp deletions.
- check_wtmpx.c: checks for wtmpx deletions. (Solaris only)
- chkproc.c: checks for signs of LKM trojans.
- chkdirs.c: checks for signs of LKM trojans.
- strings.c: quick and dirty strings replacement.
- chkutmp.c: checks for utmp deletions.

Enhancements
- new tests: common SSH brute force scanners, suspicious PHP files
- enhanced tests: login, netstat, top, backdoor
- some minor bug fixes
