NSA Private Hacking Tools

NSA's Hacking Group Hacked! Bunch of Private Hacking Tools:

The Equation Group is a highly sophisticated threat actor described by its discoverers at Kaspersky Labs as one of the most sophisticated cyber attack groups in the world and "the most advanced ... we have seen", operating alongside but always from a position of superiority with the creators of Stuxnet and Flame.[1][2]

The name Equation Group was chosen because of the group's predilection for strong encryption methods in their operations. By 2015, Kaspersky documented 500malware infections by the group in at least 42 countries, while acknowledging that the actual number could be in the tens of thousands due to its self-terminating protocol.[2][3]

They are suspected of being tied to the United States National Security Agency (NSA).[4][5] By 2015, most of their targets had been in Iran, Russia, Pakistan,Afghanistan, India, Syria, and Mali.[2]

Hacker Demands $568 Million in Bitcoin to Leak All Tools and Data

Not just this, the hackers, calling themselves "The Shadow Brokers," are also asking for 1 Million Bitcoins (around $568 Million) in an auction to release the 'best' cyber weapons and more files.

iSCSI nedir?

iSCSI, depolama aygıtlarını TCP/IP kullanan bir ağ üzerinden bağlama yöntemidir. Yerel ağ (LAN), geniş alan ağı (WAN) veya Internet üzerinden kullanılabilir. iSCSI aygıtları, ağ üzerinden erişilebilen başka bir bilgisayarda bulunan, bağlanabileceğiniz disk, teyp, CD ve benzeri diğer depolama aygıtlarıdır. ip adresli makinaya openfiler kurdum ve vg ve lun yapılandırması gerçekleştirdim.

unix domain socket interface for kafka server

Bruce is a producer daemon for Apache Kafka. Bruce simplifies clients that send messages to Kafka, freeing them from the complexity of direct interaction with the Kafka cluster. Specifically, it handles the details of:
  • Routing messages to the proper brokers, and spreading the load evenly across multiple partitions for a given topic. Clients may optionally exercise control over partition assignment, such as ensuring that a group of related messages are all routed to the same partition, or even directly choosing a partition if the client knows the cluster topology.
  • Waiting for acknowledgements, and resending messages as necessary due to communication failures or Kafka-reported errors
  • Buffering messages to handle transient load spikes and Kafka-related problems
  • Tracking message discards when serious problems occur; Providing web-based discard reporting and status monitoring interfaces
  • Batching and compressing messages in a configurable manner for improved performance
  • Optional rate limiting of messages on a per-topic basis. This guards against buggy client code overwhelming the Kafka cluster with too many messages.

radius performance testing with radperf tool


Authentication, Authorization, and Accounting. Performance, scalability, load testing, and validation.
One of the most critical steps when building a RADIUS system is performance characterisation. This means testing the system to see if both authentication (i.e., read-only) and accounting (i.e., read-write) behavior is acceptable.

In many cases, the performance will be good enough for normal loads. However, high loads are commonly seen when a NAS reboots and many users flood the network at the same time. If the system cannot handle this load, then it will be unsuitable for a production environment.

RadPerf helps you make this determination. It can send both authentication and accounting packets at varying rates. Even better, you do not need to know anything about RADIUS in order to use RadPerf.

Starting with a list of users and passwords in a CSV file, RadPerf can generate both authentication and accounting packets. It can simulate spikes in traffic, long-lived user sessions, and end-to-end user behavior.

Once RadPerf has finished testing, it produces a set of reports that summarize offered load versus accepted load. Total accepted packets per second can quickly be determined. These reports gives you the data that you need to make an informed decision about placing a system into production.


radperf-u14.04# ./radperf -A1,5 -c 1 -p 100 -s -f test.csv auth mysecretkey

NTRadPing 1.5 RADIUS Test Utility

Posted:20 Aug 2004
File Size:71KB
Publisher:Arndt Stajta

NTRadPing is a useful tool for testing installations of your RADIUS servers. Through NTRadPing you can simulate authentication and accounting requests and send them to the RADIUS server making NTRadPing act as a NAS client.
Before you send the request to the server, you need to configure the server IP address, the RADIUS secret key stored in the server clients file, and a username.
All the other parameters are optional.
On accounting requests, the "Acct-Session-Id" attribute is also added automatically if you do not explicitly enter it in the request attribute list.
If you issue an accounting request, then the RADIUS attribute "Acct-Status-Type" is added automatically by NTRadPing depending on the type of accounting request you have chosen (start, stop or update).
In the lower left list box you can add as many RADIUS attributes as you like to your request. The list of available attributes and the relevant values in the two drop down boxes depend on the dictionary file RADDICT.DAT.
By checking the "CHAP" checkbox, you may force NTRadPing to issue authentication requests with a CHAP password instead of a default (PAP) password.
In the right list box you will get results about the RADIUS request, along with a complete dump of all the returned RADIUS attributes.
The parameters entered in the main window are preserved even after closing the application (they are stored in the registry).
