Setting Alsa default device to HDMI

Configuration required in /etc/asound.conf - to change default audio PCM to HDMI
*# cat /etc/asound.conf
pcm.!default {
type plug
slave.pcm "hdmi:0,0"
}
* (this is the same "hdmi device" that can be found in Kodi's guisettings.xml, and in "aplay -L")
* alsactl --force restore #loads the new config; no reboot required
* to test if it was taken as 'default':
* speaker-test -c 2 -r 48000
* If this works, librespot is going to work as well
* Note that the output of aplay -L still shows "ALC892 Analog" as the default audio device - this is irrelevant

EdgeSwitch import/export config

(UBNT EdgeSwitch) >enable

(UBNT EdgeSwitch) #ip ssh server enable

(UBNT EdgeSwitch) #copy system:running-config nvram:factory-defaults     

This operation may take a few minutes.
Management interfaces will not be available during this time.

Are you sure you want to save? (y/n) y
#
Config file 'factory-defaults' created successfully .

Configuration Saved!

(UBNT EdgeSwitch) #clear config

At this point even after clear config we will have ssh enabled because its set in factory-defaults and 'clear config' reverts to it.

Get current config.

(UBNT EdgeSwitch) #copy system:running-config tftp://192.168.1.66/config1

Edit it by your desire. Add whatever configuration you need.

(UBNT EdgeSwitch) #copy tftp://192.168.1.66/config1 nvram:script config1.scr


(UBNT EdgeSwitch) #script apply config1.scr

If we need to change something again do 'clear config' first. Then download new config and apply it.

To transfer config across reboots:

(UBNT EdgeSwitch) #copy system:running-config nvram:startup-config

Solaris Bridge/Switch

The idea is that we need to use 4 x 10Gbe interfaces on a Solaris box for switch for 4 hypervisors and at the same time have connection from the hypervisors to the storage (the same 4 x 10 Gbe box)

USBCCID Dissection & B-Trust Reader/Writer ACR38T

Започвам едно разследване за което е силно вероятно да нямам никакво време да продължа, но това няма да ми попречи да документирам днешните си занимaния.

Кратка предистория:
Имам КЕП (Квалифициран Електронен Подпис) издаден от B-Trust. Като всяка институция в нашата родина тези хора са безкрайно некохерентни в използвана терминология и скачат от преводен термин на български в някакви заемки от чужд език които дори според производителя на устройството не са такива. Пример 'SO PIN' и 'Unblock PIN' са едно и също нещо според тях а на родната публика това по-скоро е известно като 'PUK'.
Понеже в случя става дума за четене на информация от SIM карта на мен ми се струва че употребата на PUK е далеч по-добра или е трябвало поне да се придъжат към терминологията на производителя 'SO PIN'. Но това е друга бира. По темата:

Рекох да си сменям пиновете на устройството и понеже съм много чевръст в пръстите успях да си сменя потребителския пас (PIN - ако се придържаме към телефонните термини) и в опит да си сменя PUK видях как attempts left полето се смалява от 3 към 0 и ме известява че видиш ли съм си блокирал картата. Добре обаче това изобщо не е вярно тъй като устройството работи, а с въведен правилен PIN даже подписва официални документи и банкови плащания.

И почвам да си мисля - SIM картата е носител на информация. Като такъв от него може да се чете. Добре обаче явно и без аутентикация от какъвто и да е тип може и да се пише (може и да е частен случай, но писането в attempts полето е възможно). Е щом е възможно аз защо не зема да си запиша там 999 и да си тествам с каквито там пароли си мисля че съм сложил.

Поразрових в нета и се оказва че тия хора в Белгия ги ползват тези устройства и за други неща и един младеж си е написал дъмпвачка:

https://github.com/xofc/Beid2html

Кода е толкова лалав че все едно аз съм го писал което не е задължително лошо понеже му разбирам какво прави. Човека ползва libusb-1.0

В неговият случай не е писано за същото устройство и съоетвено се налага да се смени usb id-то от хардкоднатото при него 1a44:0870 на 072f:90cc


След тази смяна връзката с устройството окача и той се впуска да му викне един статус:

if (libusb_bulk_transfer(udevp, 0x01, bufout, sizeof(bufout), &n, 1000) < 0)
  {
  fprintf(stderr, "bulk-out failed\n");
  perror("PC_to_RDR_GetSlotStatus");
  return;
  }

Хубаво прави ама много бързо се отказва. След като снифнах с wireshark как си говорят купешкия app и девайса се оказва, че традицията повелява не един, не два а точно 5 пъти да му искаш статус а то да се прави че не разбира. И чак след петия път да му пуснеш един пауър он:

И след пауър онът девайса вече съвсем културно връща  EJCOPv241 за Chip Operating System.

И почват да си говорят с дата блоци. Но кога ще ги разнищя те какви са...
to be continued (or not).

Linux Bridge to act like hub

If in need to make a linux bridge very stupid and act like hub:

brctl setageing <bridgename> 0 




This command tells Linux to forget every MAC address that it sees on
the bridge, making it act as a hub.



Lets say you have a vmbr0 with eth0 and tap0 in it and have a VM started with attached tap0 (or you choose it as vmbr0). If you link eth0 to your switch's mirroring port you wont RX a great deal of the traffic because usually linux bridge acts as switch and does not recognize the VM as endpoint for the traffic.

Above command will give you a way to have a VM that listens a mirrored port (so NIDS could be on VM).

You are welcome!

[REPOST] Using Facebook Notes to DDoS any website

Facebook Notes allows users to include <img> tags. Whenever a <img> tag is used, Facebook crawls the image from the external server and caches it. Facebook will only cache the image once however using random get parameters the cache can be by-passed and the feature can be abused to cause a huge HTTP GET flood.

Steps to re-create the bug as reported to Facebook Bug Bounty on March 03, 2014.

Step 1. Create a list of unique img tags as one tag is crawled only once

<img src=http://targetname/file?r=1></img>
<img src=http://targetname/file?r=2></img>
        ..
<img src=http://targetname/file?r=1000></img>

Step 2. Use m.facebook.com to create the notes. It silently truncates the notes to a fixed length.
 
Step 3. Create several notes from the same user or different user. Each note is now responsible for 1000+ http request.

Step 4. View all the notes at the same time. The target server is observed to have massive http get flood. Thousands of get request are sent to a single server in a couple of seconds. Total number of facebook servers accessing in parallel is 100+.

Initial Response: Bug was denied as they misinterpreted the bug would only cause a 404 request and is not capable of causing high impact.
After exchanging few emails I was asked to prove if the impact would be high. I fired up a target VM on the cloud and using only browsers from three laptops I was able to achieve 400+ Mbps outbound traffic for 2-3 hours.

Number of Facebook Servers: 127

Of course, the impact could be more than 400 Mbps as I was only using browser for this test and was limited by the number of browser thread per domain that would fetch the images. I created a proof-of-concept script that could cause even greater impact and sent the script along with the graph to Facebook.

On April 11, I got a reply that said

Thank you for being patient and I apologize for the long delay here. This issue was discussed, bumped to another team, discussed some more, etc.
In the end, the conclusion is that there’s no real way to us fix this that would stop “attacks” against small consumer grade sites without also significantly degrading the overall functionality.
Unfortunately, so-called “won’t fix” items aren’t eligible under the bug bounty program, so there won’t be a reward for this issue. I want to acknowledge, however, both that I think your proposed attack is interesting/creative and that you clearly put a lot of work into researching and reporting the issue last month. That IS appreciated and we do hope that you’ll continue to submit any future security issues you find to the Facebook bug bounty program.

I’m not sure why they are not fixing this. Supporting dynamic links in image tags could be a problem and I’m not a big fan of it. I think a manual upload would satisfy the need of users if they want to have dynamically generated image on the notes.

I also see a couple of other problems with this type of abuse:

• A scenario of traffic amplification: when the image is replaced by a pdf or video of larger size, Facebook would crawl a huge file but the user gets nothing.
• Each Note supports 1000+ links and Facebook blocks a user after creating around 100 Notes in a short span. Since there is no captcha for note creation, all of this can be automated and an attacker could easily prepare hundreds of notes using multiple users until the time of attack when all of them is viewed at once.

Although a sustained 400 Mbps could be dangerous, I wanted to test this one last time to see if it can indeed have a larger impact.
Getting rid of the browser and using the poc script I was able to get ~900 Mbps outbound traffic.

I was using an ordinary 13 MB PDF file which was fetched by Facebook 180,000+ times, number of Facebook servers involved was 112.

We can see the traffic graph is almost constant at 895 Mbps. This might be because of the maximum traffic imposed on my VM on the cloud which is using a shared Gbps ethernet port. It seems there is no restriction put on Facebook servers and with so many servers crawling at once we can only imagine how high this traffic can get.

After finding and reporting this issue, I found similar issues with Google which I blogged here. Combining Google and Facebook, it seems we can easily get multiple Gbps of GET Flood.

Facebook crawler shows itself as facebookexternalhit. Right now it seems there is no other choice than to block it in order to avoid this nuisance.

[Update1]

https://developers.facebook.com/docs/ApplicationSecurity/ mentions a way to get the list of IP addresses that belongs to Facebook crawler.

whois -h whois.radb.net —‘-i origin AS32934′| grep ^route

Blocking the IP addresses could be more effective than blocking the useragent.

I’ve been getting a lot of response on the blog and would like to thank the DOSarrest team for acknowledging the finding with an appreciation token.

[Update 2]

POC scripts and access log can now be accessed from Github. The script is very simple and is a mere rough draft. Please use them for research and analysis purposes only.

The access logs are the exact logs I used for ~900 Mbps test. In the access logs you will find 300,000+ requests from Facebook. Previously, I only counted the facebookexternalhit/1.1, it seems that for each img tag, there are two hits i.e. one from externalhit version 1.0 and one from 1.1. I also tried Google during the test and you will find around 700 requests from Google.

BANG!


Two ways from now:
1. Clean up this container as much as possible.
Stop it. Commit and use it like that.


2. Get your debs. Get your configs. Place on the same folder as your Dockerfile and edit the Dockerfile (for config files you dont need RUN just add them to the correct places).
ADD somefile.deb /somewhere/somefile.deb
RUN dpkg -i /somewhere/somefile.deb

This will 1st copy the file then install it in the instance.

Also add
CMD ["/usr/sbin/named","-4","-u","bind","-n","1","-c","/etc/bind/named.conf","-f"]
at the end. This will be your run command when you start the container.
A nice little "-g" at the end will let you see all the logs that bind spits out when you just attach ... beware if you attach and then ^C you will stop your container instance.

build container
run it
congrats you have a brand new bind9 on a container with dlz-mysql.

Notice: since i am not planning to set mysql on the same container as bind i am not getting in depth of setting the mysql and records in the last Docker setup.

Make this yourself you lazy nerds!

indexing vms on separate vmware ESXi servers

When there is no Enterprise license for ESXi there is usually more than one separate servers and if no proper documentation is kept you can easily forget where is your vm (on which hypervisor).

Here is a handy little python script that will show all vms on a list of hosts.
It uses pysphere for esx communication and yaml for config file. Also some commented parts that give more info if you uncomment.

getvms.py
#!/usr/bin/python

import yaml
from pysphere import *

def listvms(server,hv):
    vmlist = server.get_registered_vms()
    for i in vmlist:
        vm1 = server.get_vm_by_path(i)
        print ("%s -") % hv ,
        print vm1.get_properties()['name']



f = open('config.yaml')

Apache + LDAP + SSL + Proxy frontend for proprietary web application that offers no authentication.

 Lets say we have a web application that we can't/don't want to tamper with and offers no authentication. It runs on port 8000. Offers no ssl.

Do block port 8000 on all interfaces except for 127.0.0.1.
iptables -A INPUT -p tcp -d !127.0.0.1 --dport 8000 -j DROP

Use the following configuration for apache.

Listen 80
Listen 443
LDAPVerifyServerCert off
LDAPTrustedMode SSL
LDAPTrustedGlobalCert CERT_BASE64 /etc/httpd/cert1.pem
LDAPTrustedGlobalCert KEY_BASE64 /etc/httpd/key1.pem

Windows Events to Syslog

 To have all logs transfered in the same way on linux dominating network here is a great tool:  
https://code.google.com/p/eventlog-to-syslog/

Also accepts filtering using XPath expressions.

Regex web testers and tutorials/books

Inspired by regexbuddy. Works pretty fine and is web so can be used if you are away of your usual workplace and preffered software

http://regexpal.com/

Here is another one -  http://www.rubular.com/

Here is a handy guide: http://www.regular-expressions.info/quickstart.html

Still work in progress but since i like the author here is a "Learn the hard way" book on regex: http://regex.learncodethehardway.org/book/

openssl Commands

Source:  https://www.sslshopper.com/article-most-common-openssl-commands.html

 Again copy/pasta to have it near when needed:

General OpenSSL Commands

These commands allow you to generate CSRs, Certificates, Private Keys and do other miscellaneous tasks.

• Generate a new private key and Certificate Signing Request

  openssl req -out CSR.csr -new -newkey rsa:2048 -nodes -keyout privateKey.key

• Generate a self-signed certificate (see How to Create and Install an Apache Self Signed Certificate for more info)

  openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privateKey.key -out certificate.crt

• Generate a certificate signing request (CSR) for an existing private key

  openssl req -out CSR.csr -key privateKey.key -new

• Generate a certificate signing request based on an existing certificate

  openssl x509 -x509toreq -in certificate.crt -out CSR.csr -signkey privateKey.key

• Remove a passphrase from a private key

  openssl rsa -in privateKey.pem -out newPrivateKey.pem

Checking Using OpenSSL

If you need to check the information within a Certificate, CSR or Private Key, use these commands. You can also check CSRs and check certificates using our online tools.

• Check a Certificate Signing Request (CSR)

  openssl req -text -noout -verify -in CSR.csr

• Check a private key

  openssl rsa -in privateKey.key -check

• Check a certificate

  openssl x509 -in certificate.crt -text -noout

• Check a PKCS#12 file (.pfx or .p12)

  openssl pkcs12 -info -in keyStore.p12

Debugging Using OpenSSL

If you are receiving an error that the private doesn't match the certificate or that a certificate that you installed to a site is not trusted, try one of these commands. If you are trying to verify that an SSL certificate is installed correctly, be sure to check out the SSL Checker.

• Check an MD5 hash of the public key to ensure that it matches with what is in a CSR or private key

  openssl x509 -noout -modulus -in certificate.crt | openssl md5
  openssl rsa -noout -modulus -in privateKey.key | openssl md5
  openssl req -noout -modulus -in CSR.csr | openssl md5

• Check an SSL connection. All the certificates (including Intermediates) should be displayed

  openssl s_client -connect www.paypal.com:443

Converting Using OpenSSL

These commands allow you to convert certificates and keys to different formats to make them compatible with specific types of servers or software. For example, you can convert a normal PEM file that would work with Apache to a PFX (PKCS#12) file and use it with Tomcat or IIS. Use our SSL Converter to convert certificates without messing with OpenSSL.

• Convert a DER file (.crt .cer .der) to PEM

  openssl x509 -inform der -in certificate.cer -out certificate.pem

• Convert a PEM file to DER

  openssl x509 -outform der -in certificate.pem -out certificate.der

• Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM

  openssl pkcs12 -in keyStore.pfx -out keyStore.pem -nodes

  You can add -nocerts to only output the private key or add -nokeys to only output the certificates.
• Convert a PEM certificate file and a private key to PKCS#12 (.pfx .p12)

  openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt

Java Keystore commands

Source:  http://www.sslshopper.com/article-most-common-java-keytool-keystore-commands.html

 

I will copy/pasta the part that i use so I will have it handy here.

 

Java Keytool Commands for Creating and Importing

These commands allow you to generate a new Java Keytool keystore file, create a CSR, and import certificates. Any root or intermediate certificates will need to be imported before importing the primary certificate for your domain.

• Generate a Java keystore and key pair keytool -genkey -alias mydomain -keyalg RSA -keystore keystore.jks -keysize 2048
  
• Generate a certificate signing request (CSR) for an existing Java keystore keytool -certreq -alias mydomain -keystore keystore.jks -file mydomain.csr
  
• Import a root or intermediate CA certificate to an existing Java keystore keytool -import -trustcacerts -alias root -file Thawte.crt -keystore keystore.jks
  
• Import a signed primary certificate to an existing Java keystore keytool -import -trustcacerts -alias mydomain -file mydomain.crt -keystore keystore.jks
  
• Generate a keystore and self-signed certificate (see How to Create a Self Signed Certificate using Java Keytool for more info) keytool -genkey -keyalg RSA -alias selfsigned -keystore keystore.jks -storepass password -validity 360 -keysize 2048
  

Java Keytool Commands for Checking

If you need to check the information within a certificate, or Java keystore, use these commands.

• Check a stand-alone certificate keytool -printcert -v -file mydomain.crt
  
• Check which certificates are in a Java keystore keytool -list -v -keystore keystore.jks
  
• Check a particular keystore entry using an alias keytool -list -v -keystore keystore.jks -alias mydomain
  

Other Java Keytool Commands

• Delete a certificate from a Java Keytool keystore keytool -delete -alias mydomain -keystore keystore.jks
  
• Change a Java keystore password keytool -storepasswd -new new_storepass -keystore keystore.jks
  
• Export a certificate from a keystore keytool -export -alias mydomain -file mydomain.crt -keystore keystore.jks
  
• List Trusted CA Certs keytool -list -v -keystore $JAVA_HOME/jre/lib/security/cacerts
  
• Import New CA into Trusted Certs keytool -import -trustcacerts -file /path/to/ca/ca.pem -alias CA_ALIAS -keystore $JAVA_HOME/jre/lib/security/cacerts
  

openssl verify

Make a folder to contain your public certificates:

#mkdir certs
#cd certs

Get public cert for the server you want to check:
#openssl s_client -showcerts -connect server:port

Copy from the "-----BEGIN CERTIFICATE-----" to the "-----END CERTIFICATE-----" , and save it in a file ending in .pem

Get issuer (CA) root certificate ("Certification Authority Root Certificate")
should be provided by your issuer or if you are your own CA you should know how to get this. Place it in the same directory as the certificate of your server (the one you are testing).

 Rehash the certificates. This is basically creating a link files to your .pem files. Names are based on the certificate content so openssl command will be able to operate on the files.

#for file in *.pem; do ln -s $file `openssl x509 -hash -noout -in $file`.0; done

Verify the certificate:

#openssl s_client -CApath . -connect server:port

Output should be similar to:
..
