 Eureka! A research team featuring dozens of scientists working in partnership with Google‘s quantum computing labs may have created the world’s first-time crystal inside a quantum computer. This is the kind of news that makes me want to jump up and do a happy dance. These scientists may have produced an entirely new phase of matter. I’m going to do my best to explain what that means and why I personally believe this is the most important scientific breakthrough in our lifetimes. However, for the sake of clarity, there are two points I need to make first: 1. Time crystals are a wickedly difficult concept to understand and even harder to explain. 2. The Google team might have created time crystals. This is pre-print research and has yet to receive full peer review. Until the rest of the scientific community has time to review and replicate the work, we can’t say for sure it’s legitimate. In colloquial terms, it’s a big screw you to Sir Isaac Newton. Time crystals are a new phase of matter. For the sake of simplicity, let’s imagine a cube of ice. When you put a cube of ice in a glass of water, you’re introducing two separate entities (the ice cube and the liquid water) to each other at two different temperatures. Everyone knows that the water will get colder (that’s why we put the ice in there) and, over time, the ice will get warmer and turn into water. Eventually, you’ll just have a glass of room-temperature water. We call this process “thermal equilibrium.” Most people are familiar with Newton’s first law of motion, it’s the one that says “an object at rest tends to stay at rest and an object in motion tends to stay in motion.” An important side-effect of this law of physics is that it means a perpetual motion machine is classically impossible. According to classical physics, the universe is always moving towards entropy. In other words: if we isolate an ice cube and a room-temperature glass of water from all other external forces, the water will always melt the ice cube. The entropy (the movement towards change) of any system will always remain the same if there are no processes, and it will always increase if there are processes. Since our universe has stars exploding, black holes sucking, and people lighting things on fire – chemical processes – entropy is always increasing. Except when it comes to time crystals. Time crystals don’t give a damn what Newton or anyone else thinks. They’re lawbreakers and heart-takers. They can, theoretically, maintain entropy even when they’re used in a process. Think about a crystal you’re familiar with, such as a snowflake. Snowflakes aren’t just beautiful because each one is unique, they’re also fascinating formations that nearly break the laws of physics themselves. Crystalline structures form in the physical world because, for whatever fundamental scientific reason, the atoms within them “want” to exist in certain exact points. “Want” is a really weird word to use when we’re talking about atoms – I’m certainly not implying they’re sentient – but it’s hard to describe the tendency toward crystalline structures in abstracts such as “why.” A time crystal is a new phase of matter that, simplified, would be like having a snowflake that constantly cycled back and forth between two different configurations. It’s a seven-pointed lattice one moment and a ten-pointed lattice the next, or whatever. What’s amazing about time crystals is that when they cycle back and forth between two different configurations, they don’t lose or use any energy. Time crystals can survive energy processes without falling victim to entropy. The reason they’re called time crystals is that they can have their cake and eat it too. They can be in a state of having eaten the whole cake, and then cycle right back to a state of still having the cake – and they can, theoretically, do this forever and ever. Most importantly, they can do this inside of an isolated system. That means they can consume the cake and then magically make it reappear over and over again forever, without using any fuel or energy. Further information can be found on OUR FORUM.  A newly uncovered security flaw in the Windows operating system can be exploited to coerce remote Windows servers, including Domain Controllers, to authenticate with a malicious destination, thereby allowing an adversary to stage an NTLM relay attack and completely take over a Windows domain. The issue, dubbed "PetitPotam," was discovered by security researcher Gilles Lionel, who shared technical details and proof-of-concept (PoC) code last week, noting that the flaw works by forcing "Windows hosts to authenticate to other machines via MS-EFSRPC EfsRpcOpenFileRaw function." MS-EFSRPC is Microsoft's Encrypting File System Remote Protocol that's used to perform "maintenance and management operations on encrypted data that is stored remotely and accessed over a network." Specifically, the attack enables a domain controller to authenticate against a remote NTLM under a bad actor's control using the MS-EFSRPC interface and share its authentication information. This is done by connecting to LSARPC, resulting in a scenario where the target server connects to an arbitrary server and performs NTLM authentication. By forcing the targeted computer to initiate an authentication procedure and share its hashed passwords via NTLM, the PetitPotam attack can be chained to an exploit targeting Windows Active Directory Certificate Services (AD CS) to seize control of the entire domain. "An attacker can target a Domain Controller to send its credentials by using the MS-EFSRPC protocol and then relaying the DC NTLM credentials to the Active Directory Certificate Services AD CS Web Enrollment pages to enroll a DC certificate," TRUESEC's Hasain Alshakarti said. "This will effectively give the attacker an authentication certificate that can be used to access domain services as a DC and compromise the entire domain. While disabling support for MS-EFSRPC doesn't stop the attack from functioning, Microsoft has since issued mitigations for the issue while characterizing "PetitPotam" as a "classic NTLM relay attack," which permit attackers with access to a network to intercept legitimate authentication traffic between a client and a server and relay those validated authentication requests in order to access network services. "To prevent NTLM Relay Attacks on networks with NTLM enabled, domain administrators must ensure that services that permit NTLM authentication make use of protections such as Extended Protection for Authentication (EPA) or signing features such as SMB signing," Microsoft noted. "PetitPotam takes advantage of servers where the Active Directory Certificate Services (AD CS) is not configured with protections for NTLM Relay Attacks."To safeguard against this line of attack, the Windows maker is recommending that customers disable NTLM authentication on the domain controller.
