retrieve lots of passwords stored on a local computer

The LaZagne project is an open source application used to retrieve lots of passwords stored on a local computer. Each software stores its passwords using different techniques (plaintext, APIs, custom algorithms, databases, etc.). This tool has been developed for the purpose of finding these passwords for the most commonly-used software.

suricata Error: datalink type 65535 not yet supported in module DecodeAFP solution

 <Error> - [ERRCODE: SC_ERR_DATALINK_UNIMPLEMENTED(38)] - Error: datalink type 65535 not yet supported in module DecodeAFP

Solution:

Edit suricata-4.0.3/src/source-af-packet.c. I changed default datalink type to raw. That solved my problem.

suricata-4.0.3/src/source-af-packet.c:

   2295 TmEcode DecodeAFP(ThreadVars *tv, Packet *p, void *data, PacketQueue *pq, PacketQueue *postpq)

   2296 {

   2297     SCEnter();

   2298     DecodeThreadVars *dtv = (DecodeThreadVars *)data;

   2299 

   2300     /* XXX HACK: flow timeout can call us for injected pseudo packets

   2301      *           see bug: https://redmine.openinfosecfoundation.org/issues/1107 */

   2302     if (p->flags & PKT_PSEUDO_STREAM_END)

   2303         return TM_ECODE_OK;

   2304 

   2305     /* update counters */

   2306     DecodeUpdatePacketCounters(tv, dtv, p);

   2307 

   2308     /* If suri has set vlan during reading, we increase vlan counter */

   2309     if (p->vlan_idx) {

   2310         StatsIncr(tv, dtv->counter_vlan);

   2311     }

   2312 

   2313     /* call the decoder */

   2314     switch (p->datalink) {

   2315         case LINKTYPE_ETHERNET:

   2316             DecodeEthernet(tv, dtv, p,GET_PKT_DATA(p), GET_PKT_LEN(p), pq);

   2317             break;

   2318         case LINKTYPE_LINUX_SLL:

   2319             DecodeSll(tv, dtv, p, GET_PKT_DATA(p), GET_PKT_LEN(p), pq);

   2320             break;

   2321         case LINKTYPE_PPP:

   2322             DecodePPP(tv, dtv, p, GET_PKT_DATA(p), GET_PKT_LEN(p), pq);

   2323             break;

   2324         case LINKTYPE_RAW:

   2325             DecodeRaw(tv, dtv, p, GET_PKT_DATA(p), GET_PKT_LEN(p), pq);

   2326             break;

   2327         case LINKTYPE_NULL:

   2328             DecodeNull(tv, dtv, p, GET_PKT_DATA(p), GET_PKT_LEN(p), pq);

   2329             break;

   2330         default:

   2331 //            SCLogError(SC_ERR_DATALINK_UNIMPLEMENTED, "Error: datalink type %" PRId32 " not yet supported in module DecodeAFP", p->datalink);

   2332 //            DecodePPP(tv, dtv, p, GET_PKT_DATA(p), GET_PKT_LEN(p), pq);

   2333             DecodeRaw(tv, dtv, p, GET_PKT_DATA(p), GET_PKT_LEN(p), pq);

   2334 //            DecodeEthernet(tv, dtv, p,GET_PKT_DATA(p), GET_PKT_LEN(p), pq);

   2335             break;

Linux Privilege Escalation Scripts

LinEnum
http://www.rebootuser.com/?p=1758
This tool is great at running through a heap of things you should check on a Linux system in the post exploit process. This include file permissions, cron jobs if visible, weak credentials etc. The first thing I run on a newly compromised system.

LinuxPrivChecker
http://www.securitysift.com/download/linuxprivchecker.py
This is a great tool for once again checking a lot of standard things like file permissions etc. The real gem of this script is the recommended privilege escalation exploits given at the conclusion of the script. This is a great starting point for escalation.

g0tmi1k’s Blog
http://blog.g0tmi1k.com/2011/08/basic-linux-privilege-escalation/
Not so much a script as a resource, g0tmi1k’s blog post here has led to so many privilege escalations on Linux system’s it’s not funny. Would definitely recommend trying out everything on this post for enumerating systems.

windows file sharing operations

list all active connections:

net use

remove all active connections:

net use * /delete

remove specific connection

net use \\<ip>\<share> /delete

add connection

net use \\<ip>\<share> /user:domain/username <password> /persistent:yes

make symbolic link for file share

mklink /d c:\temp\<localpath> \\<ip>\<share>

php reverse shell

Remote file inclusion açıkları için kullanabileceğiniz bir araç.

netcat ile dinlediğiniz bir porta geri dönüş yapması için 'python -m SimpleHTTPServer 80' ile servis ederek erişim sağlayabilirsiniz.

SEP: how can we detect 'application and device control feature' enabled on a sep client machine

Aşağıda bu kontrolü yapabileceğiniz birden fazla yöntem paylaşıyorum. İstediğiniz şekilde sonuç alamazsanız uygun zamanınızda beraber gözatabiliriz.

1.

Kurulum paketinizde yer alan setAid.ini dosyada yer alan;

"DCMain=1"

Application Control and Device Control yükleneceği anlamına gelir bu şekilde kontrol edebilirsiniz.

Örnek ekran görüntüleri:

Setup paketimi extract ettiğimdeki dosya içeriği:

2.

Diğer bir yöntem olarak aşağıdaki logları analiz ederek bunu tespit edebilirsiniz.

Monitors -> Logs -> Application and Device Control,

Monitors -> Logs -> Log type: Application and Device Control -> Advanced Settings -> Event Type: Application Control Driver -> View Log

3.

sc query sysplant

komutu ile application and device control tarafından kullanılan servis durumunu sorgulayabilirsiniz.

Örnek:

Komut satırından ram model ve hız bilgileri öğrenme

Symantec Endpoint Protection: SEPM üzerinden Sep Client nasıl disable hale getirilir?

SEPM ve client arasındaki haberleşme smc servisi sayesinde bina edilir. Eğer bu servis SEPM aracılığıyla kapatılırsa aradaki iletişim kesileceği için yeniden başlatılamaz. Dolasıyla bu SEPM üzerinden client tarafındaki servisin kapatılması tavsiye edilmez.

Symantec Endpoint Protection: client tarafında tanımlanan exception tanımları nasıl kontrol edilir?

SEPM (Symantec Enterprise Protection Manager) aracılığıyla tanımlanan exception tanımları client tarafında nasıl kontrol edilir?

Eğer windows kullanıyorsanız bu için açağıdaki registery yollarını kontrol edebilirsiniz.

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Symantec\SymantecEndpoint

Extremely Fast MySQL Backup and Restore Using Mydumper/Myloader

Mydumper and Myloader are utility software programs that allow you to perform extremely fast and reliable multi-threaded MySQL backup and restore which is written in the C programming language.

It was initially developed by MySQL engineers who later moved to Facebook. Mydumper is approximately 10 times faster than the mysqldump tools typically used for backups.
