That’s why this bug is so cool and provides an opportunity to exploit devices literally with zero-click interaction at any state of wireless connection (even when a device isn’t connected to any network). For example, one can do RCE in just powered-on Samsung Chromebook. So just to summarize:
- It doesn’t require any user interaction.
- It can be triggered every 5 minutes in case of GNU/Linux operating system.
- It doesn’t require the knowledge of a Wi-Fi network name or passphrase/key.
- It can be triggered even when a device isn’t connected to any Wi-Fi network, just powered on.

In this research, I used ALFA networks wireless adapter in the monitor mode, which is based on Realtek 8187 wireless chipset. The exploit can be implemented with python Scapy framework. For some reason, Ubuntu GNU/Linux distrubution isn’t good enough to inject Wi-Fi frames fast, so it is better to use Kali.
In researchers’ own words “every system on which HeadSetup […] was installed at any time in the past […] remains vulnerable” until users manually review the Trusted Root Certificate Store and remove the two certificates, or until the certificates expire –which could be January 13, 2027, or July 27, 2037, respectively.

Every F-35 squadron, no matter the country, has a 13-server ALIS package that is connected to the worldwide ALIS network. Individual jets send logistical data back to their nation’s Central Point of Entry, which then passes it on to Lockheed’s central server hub in Fort Worth, Texas. In fact, ALIS sends back so much data that some countries are worried it could give away too much information about their F-35 operations.

Hackers could conceivably introduce bad data in the JRE that could compromise the safety of a mission, shortening the range of a weapon system so that a pilot thinks she is safely outside the engagement zone when she is most certainly not.
It’s highly likely these vulnerabilities are a known detectable exploit vector. Any military aircraft should be able to perform its mission disconnected from a network — except for perhaps drones.
QUIC stands for “Quick UDP Internet Connections” and is, itself, Google’s attempt at rewriting the TCP protocol as an improved technology that combines HTTP/2, TCP, UDP, and TLS (for encryption), among many other things.

Since then, HTTP-over-QUIC support was added inside Chrome 29 and Opera 16, but also in LiteSpeed web servers. While initially, only Google’s servers supported HTTP-over-QUIC connections, this year, Facebook also started adopting the technology.
Court says an attacker was only required to send malformed UDP packets to a target’s Steam client, which would have triggered the bug and allowed him to run malicious code on the target’s PC.

This also appears to be happening with Xfinity’s protected browsing feature. A reader alerted us that, when he tried to access TorrentFreak, access was denied stating that a “suspicious” site was ahead.

Portugal isn’t the only country allowing tiering of internet services. In Britain, the internet service provider Vodaphone charges about $33 a month for basic service but offers several “passes” allowing unlimited video or music streaming, social media usage, or chat, at additional tariffs of up to $9.30 per month.

The U.S. software weapon would have allowed the spy agency’s hackers to break into potentially millions of Windows computers by exploiting a flaw in how certain versions of Windows implemented a network protocol commonly used to share files and to print.

This security update resolves vulnerabilities in Microsoft Edge. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Microsoft Edge. An attacker who successfully exploited these vulnerabilities could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
SpaceX hopes to start testing its satellites before the end of this year and continuing through the early months of 2018. If that’s successful, the company plans to launch satellites in phases between 2019 and 2024, after which the system will be at full capacity.

An attacker can exploit the vulnerability by sending a malformed protocol-specific Telnet command while establishing a connection to the affected device, because of a flaw in how the protocol fails to properly process some commands.
Cisco said that there are “no workarounds” to address the vulnerability, but it said that disabling Telnet would “eliminate” some risks.
