Top Best Hacking Tools Of 2018 For Windows, Linux and Mac OS X Here is the list of top best ethical hacking tools 2018 for Windows PC, Linux system and MAC OS. These are the must have tools for every hacker required for different purposes. The Competition. DaisyDisk ($10) is a beautiful disk space analyzer. It's the preference of many Mac users. What it does differently is display disk usage data as a sunburst map, which some may.
- Log in to your Mac with an administrator account.
- While holding down the Option key, then choose Apple menu () > System Information (or System Profiler).
- Select Network from the list on the left side of the System Information window.
- Select the network interface (such as Wi-Fi or Ethernet) from the list of active services on the right side of the window.
- From the details section at the bottom of the window, find 'BSD Device Name.' In the example pictured, the BSD device name for Wi-Fi is en0.
Capture the packet trace
- Open Terminal, which is in the Utilities folder of your Applications folder,.
- Type the following command, but replace
BSDnamewith the BSD device name (such as en0, en1, or ppp0) from System Information:
sudo tcpdump -i BSDname -s 0 -B 524288 -w ~/Desktop/DumpFile01.pcap
- Press Return, then enter your administrator password when prompted.
- Terminal should say
tcpdump: listening on...to indicate that it's listening for activity on that network interface.
- While Terminal is open, perform the network function that you want to test.
- When the network function is complete, return to Terminal and press Control-C to capture the packet trace. Terminal saves it to your desktop in a file named 'DumpFile01.pcap.'
- To see the contents of the file, use this command in Terminal:
tcpdump -s 0 -n -e -x -vvv -r ~/Desktop/DumpFile01.pcap
- To capture additional packet traces, modify the Terminal command to increment the number of the saved file (such as DumpFile02.pcap and DumpFile03.pcap).
The Apple Developer website has more information about packet traces. When troubleshooting a network connection, you should know your computer's model, macOS version, IP address (and the destination IP address), and media access control (MAC) address. You should also understand your computer's role in the network activity, as well as the time of each network event associated with the issue.
When troubleshooting the connection between an AirPort Base Station and a broadband modem, restart the base station and capture its interactions with the Internet service provider while it starts up. You can restart the base station using AirPort Utility, or by briefly unplugging it from power. While testing, it's best if the base station, modem, and capturing computer are connected to an Ethernet hub, not a switch. You should also manually assign the capturing computer's IP address so that it doesn't take the DHCP lease that the base station needs (a 169.254.x.x address should suffice).
The packet trace may show that the TCP checksum of packets sent by the Mac is bad. This is because the packet trace is being captured at the link layer of the network stack, which is just before the physical network adapter where checksums are generated. This can be safely ignored.
OS X only has a few disk space analyzers, and the good news is that they're all pretty good. Nonetheless, we feel Disk Inventory X is the way to go thanks to its organization, massive amount of information, and $0 price tag.
Disk Inventory X
Platform: OS X
- Provides a basic overview of all your disks on startup
- Creates a click-able map of the data on your disk, color-coded by type
- Provides additional information about specific data when you click on an item on the map
- Can analyze the entire disk or just a specific folder
- Easily reveal specific folders and files in the Finder so you can delete them
- Shows basic information about any file or folder you select (post-analysis)
- Allows you to view your entire disk by order of file/folder size so you can see the largest space hogs

Where It Excels
Disk Inventory X is very informative and easy to use. You choose the disk you want to analyze, it runs through all the data on it, and then provides you with a color-coded map so you can see what's filling up your disk. You can then click on any portion of the map to find out more details and reveal that item in the Finder so it can be deleted (if you want to delete it, that is). What I find most useful, however, is the drawer-based list in the app that displays files and folders from largest to smallest. Although the map can be visually interesting, I find that a text-based list is easier to read as you can just see what's taking up a ton of space and what's not very easily. Disk Inventory X gives you both, so you're in good shape regardless of what you prefer. It provides all the information you'll need, in multiple ways, when analyzing your disk space.
Where It Falls Short
Best Wifi Sniffer For Mac
It isn't exactly a pretty app (like Daisy Disk, mentioned in the competition section) and the amount of information it provides might be overwhelming for some users at first. That said, these are very minor complaints. For the most part, Disk Inventory X should handle just about everything you'd want out of a disk space analyzer.
Best Sniffer For Windows
DaisyDisk ($10) is a beautiful disk space analyzer. It's the preference of many Mac users. What it does differently is display disk usage data as a sunburst map, which some may find easier to read (and definitely more pleasant to look at). DaisyDisk is very fast and very pretty. The only problem is that it cost $10, which is hard to justify for an app you probably won't use very often when there are equally useful, free alternatives.
Best Sniffer For Mac Os X
GrandPerspective (Free) is very similar to Disk Inventory X, but not quite up to par. The interface also feels a little old, combining some of the new styles of OS X 10.5+ and some of the old ones, too. It's a perfectly functional app that creates comprehensive disk usage maps, but it doesn't give you a disk overview (like Disk Inventory X and Daisy Disk) and no simple breakdown beside the map, either. That said, GrandPerspective does offer a information drawer that provides plenty of other data about your volume and what's on it. If you're not in love with Disk Inventory X and want something a little bit different, you might want to give GrandPerspective a look.
