Bro and Elasticsearch Integration

First, fix dots in ES 2.4:

Fix dots in field names

Next install Bro ElasticSearch plugin:

Bro ElasticSearch Plugin

with a couple caveats of  you'll need to cd to bro-2.4.1/aux/plugins/elasticsearch before the ./configure && make && make install, and the default plugin dir to install in is bro-install-dir/lib/bro/plugins/.


The below script to use for mappings will set all strings to not analyzed, and ip source and destinations to field type of IP:
curl -XPUT "http://localhost:9200/_template/bro_template" -d'

Maltrail Setup and Systemd Integration

Having run this app for a while now I figured this was long overdue...tested on Ubuntu 14-16:


git clone https://github.com/stamparm/maltrail.git

sudo mv maltrail /opt/

add to /etc/passwd:
maltrail:x:10000:10000::/opt/maltrail:/bin/false

add to /etc/group:
maltrail:x:10000:maltrail

edit your /opt/maltrail/maltrail.conf (interface, creds, etc...)

sudo chown -R maltrail:maltrail /opt/maltrail

create the two files below:

/lib/systemd/system/maltrail-sensor.service:

[Unit]
Description=Maltrail server

[Service]
User=maltrail
Group=maltrail
WorkingDirectory=/opt/maltrail
ExecStart=/usr/bin/nohup /usr/bin/python /opt/maltrail/server.py & disowm


[Install]
WantedBy=multi-user.target


/lib/systemd/system/maltrail-sensor.service:

[Unit]
Description=Maltrail sensor

[Service]
WorkingDirectory=/opt/maltrail
ExecStart=/usr/bin/python /opt/maltrail/sensor.py


[Install]
WantedBy=multi-user.target


then run:
sudo systemctl enable maltrail-server
sudo systemctl enable maltrail-sensor


lastly run:
sudo systemctl start maltrail-server
sudo systemctl start maltrail-sensor


updating:
sudo systemctl stop maltrail-server
sudo systemctl stop maltrail-sensor
cd /opt/maltrail
sudo cp maltrail.conf maltrail.conf.mine
sudo rm maltrail.conf
sudo git pull

copy local changes from maltrail.conf.mine to the new maltrail.conf

sudo chown -R maltrail:maltrail /opt/maltrail
sudo systemctl start maltrail-server

sudo systemctl start maltrail-sensor

The Sad State of Foxit Reader

The tl;dr is:  Foxit Reader, tracks your usage and sends it to their servers (in China!!), installs a service that you can’t uninstall without uninstalling Foxit Reader, and is not proxy aware.  There is currently no way to disable any of the cloud based functionality, or user tracking.  Long version below:

After installation, you can see the Foxit Reader Service installed (left), but no option to uninstall the service (right), whereas previous versions you could:


If you disable the service as shown above, Foxit will give you the below prompt EVERY TIME you open a pdf or start the application:








Foxit Reader sending your IP and MAC address to Foxit's servers

Logging data sent to Foxit's servers

 The below shows a list of User Agent's found in the FoxitConnectedPDFService.exe memory:




Lastly, the Detected field shows the protections Foxit has put in place on the exe:

Boleto Malspam Leads to Symmi

Boleto Malspam Leads to Symmi

It starts with an email

The pdf button goes to a servint.net link, which in turn goes to dropbox.com

We're left with BOLETO-29-06-2016.PDF.zip, which extracts to BOLETO-29-06-2016.jar.  Decompiling the jar file we see several interesting bits


the key and most of the crypto routine were pulled from avajava.com tutorials.  After decrypting the files we're left with two 64 bit files, and two 32 bit files

c4cb4fdf6369dd1342d2666171866ce5 is apparently calc.exe (?), the rest are packed with VMProtect.  VT Links:

A Concise List of Windows 10 Network Activity on Boot

So this is just a list of what sysmon sees on boot.  This is Windows 10 Pro with all the security settings set to as much strict as allowed.  This was a fresh install, updated, no applications installed, with no user interaction.  Interesting that Procmon running on Windows 10 doesn't show any of this activity.  CSV is below...read from bottom up.

A comparison of OS phone homes

Not much to say here really...so I'll let the pictures do the talking.  Each OS was turned on...that was it....no interaction for a few days at all.  Each OS was a basic install....no other applications were installed.

Ubuntu
 
El Capitan

Windows 10

Binnavi install on Windows

Great app...I couldn't find anywhere that talked about what you need to make it so here goes:

Apache Ant
Apache Maven 
Java JDK 
PostgreSQL 

Install the JDK, create a new Windows Environment Variable called JAVA_HOME that should point to install directory (e.g. C:\Program Files\Java\jdk1.8.0_60).  Extract your apache-maven-*.*.*-bin.zip and apache-ant-*.*.*-bin.zip, put them somewhere (I put mine just in "c:\", and add both to your PATH (I renamed these and mine look like: C:\apache-maven\bin;C:\apache-ant\bin).

Install PostgreSQL, and with pgAdmin create a new user (I called mine binnavi), then create a new database (I called mine binnavi) with the owner being binnavi.

Get a command prompt/powershell and cd to binnavi-master then build:

mvn dependency:copy-dependencies
ant -f src/main/java/com/google/security/zynamics/build.xml build-binnavi-fat-jar
 

Then run and point to your PostgreSQL instance:
java -jar target/binnavi-all.jar




Done.
