Penetration testing, or pentesting, is the process of probing a network or system by simulating an attack, which is used to find vulnerabilities that could be exploited by a malicious actor. The main goal of a pentest is to identify security holes and weaknesses so that the organization being tested can fix any potential issues. In a professional penetration test, there are six phases you should know.
Besides obvious features like a touchscreen and biometric sensors, the modern smartphone comes with an array of state-of-the-art hardware in the form of various sensors that help your device sense the environment around it. And if you have a Samsung handset, chances are, you have a handy feature built in that enables you to check if these sensors are functioning 100 percent.
Kali Linux is the obvious first choice of an operating system for most new hackers, coming bundled with a curated collection of tools organized into easy-to-navigate menus and a live boot option that is very newbie-friendly. But Kali isn't the only distribution targeted at pentesters, and many exciting alternatives may better fit your use-case. We've already covered BlackArch Linux, now it's time to talk about Parrot Security OS.
People love sex. They don't love talking about the possible repercussions of sex. And with dating apps such as Tinder, Grindr, and Bumble paving new ways for strangers to talk and have casual hookups, people need to be able to more comfortably have a conversation about sexual health and protection. Luckily, now there's an app for that.
When hacking Wi-Fi networks, having the right wireless adapter is essential. But hunting online for one can be a frustrating experience. To see how the handful of Kali-compatible adapters on the market measure up, I ran a series of tests to benchmark and compare their range, signal strength, and ability to enter monitor mode and perform packet injection. This should help you determine which adapter is right for your own hacking needs.
In 2013, Offensive Security released Kali Linux, a rebuild of BackTrack Linux derived from Debian. Since then, Kali has gone on to become somewhat of a standard for penetration testing. It comes preconfigured with a collection of tools accessible by a menu system, tied together with the Gnome desktop environment. However, Kali Linux isn't the only penetration-testing distribution available.

Apple released the third public beta for iOS 12.4 on the afternoon of May 28. The update arrives roughly three hours after Apple published 12.4's third developer beta, and eight days after 12.4 public beta 2. At this time, it seems beta 3 is a minor update for 12.4, which itself is a small upgrade to iOS 12 as a whole. We expect iOS 12.4's shining feature to be Apple Card support.
Texas has become the 18th state to pass a bill into law regarding autonomous vehicles, the third this month to do so.
Prion diseases are a group of infectious brain diseases that causes extensive tissue damage, resulting in sponge-like spaces in brain tissue.

Toyota is testing blockchain and distributed ledger technology (BC/DL) for data sharing for driverless cars and other applications. This could eventually reassure buyers of its upcoming high-end cars by making sure their sensitive data is secure.
Apple released iOS 12 beta 9 to public beta testers on Monday, Aug. 27. The update comes at the same time as the release of dev beta 11. This is surprising, as Apple typically releases developer betas at least a few hours before the public version. Then again, everything Apple is doing with its iOS 12 beta as of late is surprising.
Can't say we didn't see this coming — Apple released iOS 12 public beta 7 on Monday, August 20, the same day it seeded the ninth version of the beta to developers. While the two betas may have different names, public beta 7 and dev beta 9 are virtually identical, so public testers shouldn't feel as though they are missing out.
Google's new Pixel and Pixel XL smartphones are available for pre-order right now, but the general public won't start to get their hands on these devices for another week or two. Tech reporters got some hands-on time at Google's launch event on October 4th, but camera testing wasn't allowed, and the Wi-Fi coverage at the event was too flooded for real-world performance reviews.
In a surprise twist, Apple released iOS 12 public beta 8 to software testers on Thursday, Aug. 23, right alongside iOS 12 dev beta 10. The release comes as a bit of a shock, as the company released iOS 12 public beta 7 just three days earlier. The official build of iOS 12 now feels closer every day.
Apple released the third public beta for iOS 12.1 to software testers on Tuesday, Oct. 9, and there's not a whole lot to be excited about. The update came just hours after Apple released iOS 12.1 dev beta 3 to registered app developers, signaling a return to the traditional Tuesday release schedule for iOS betas. At least, for now.

Crisis averted — Apple released iOS 12 public beta 6 — not public beta 7 — to software testers Wednesday, August 15. The update comes hours after the release of dev beta 8, which replaced the short-lived seventh developer beta. Apple released dev beta 7 Monday, August 13, but quickly pulled the update due to instability and poor performance.

Black Mirror, Netflix's technology-horror anthology, never fails to provide thought-provoking entertainment centered around emerging and futuristic technologies, and the third season's second episode, "Playtest," delves deep into the worlds of mixed, augmented, and virtual reality. While designed to leave you haunted by the end, offering a more "evil" narrative than we'll likely see in our actual future, the episode explores possibilities that aren't as far off as one might think.
Right now, Apple is testing two versions of iOS. On the one hand, you have iOS 13, buggy but feature-filled. On the other, iOS 12.4. The latter just got an update to the fifth developer and public beta versions, 13 days after the release of iOS 12.4 developer beta 4.
