15 popüler ağ güvenliği aracı

1. Nmap

Nmap (“Network Mapper”) is a free and open source (license) utility for network discovery and security auditing. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap homepage.

2. Wireshark

Wireshark is a network protocol analyzer. It lets you capture and interactively browse the traffic running on a computer network. Wireshark homepage.

3. Metasploit Community edition

This helps prioritize remediation and eliminate false positives, providing true security risk intelligence. Metasploit community edition homepage.

4. Nikto2

Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 6400 potentially dangerous files/CGIs, checks for outdated versions of over 1200 servers, and version specific problems on over 270 servers. It also checks for server configuration items such as the presence of multiple index files, HTTP server options, and will attempt to identify installed web servers and software. Nikto2 homepage.

5. John the Ripper

John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. Besides several crypt(3) password hash types most commonly found on various Unix systems, supported out of the box are Windows LM hashes, plus lots of other hashes and ciphers in the community-enhanced version. John the Ripper homepage.

linux: mac spoof nasıl yapılır

* Spoof the MAC address:

sudo ifconfig en1 ether [mac address to spoof]

Where it says "[mac address to spoof]", press Command-V to paste the victim's, er, I mean the machine-to-be-spoofed's MAC address.  Your machine may require an administrator password at this point.  This is the password you use to log into OS X on your own machine.

* Confirm the spoof:

ifconfig en1 | grep ether

Your displayed MAC address should now be different from what it was before.

OS X El Capitan: how to run wireshark with iphone usb interface

Öncelikle cihazınıza ait udid bilgisini edinmeniz gerekiyor. Bu bilgiyi itunes summary kısmından öğrenebilirsiniz.


Sonrasında virtual interface oluşturmak için rvictl aracını kullanıyoruz.

localuserpc:~ root# rvictl -s en5

rvictl [-h][-l][-s <udid1> ... <udidN>][-x <udid1> ... <udidN>]

Remote Virtual Interface Tool starts and stops a remote packet capture instance 
for any set of attached mobile devices. It can also provide feedback on any attached 
devices that are currently relaying packets back to this host. 

-l, -L List currently active devices
-s, -S Start a device or set of devices
-x, -X Stop a device or set of devices

localuserpc:~ root# rvictl -s
Starting device XXX [SUCCEEDED] with interface rvi0

sonrasında çalıştırdığınızda rvi0 interface'i üzerinden filtreleme yapabilirsiniz;

localuserpc:~ root# wireshark

jq: command-line tool for parsing JSON.

Passing it through jq's parser, with the most basic option, will make it look nicer (with colors):
user@host:~$ curl -s |\
  jq '.'
  "status": "good",
  "last_updated": "2015-01-21T16:59:01Z"
Do some basic selection:
user@host:~$ curl -s |\
  jq '.status'

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.

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.
