Mandiant Releases NTLMv1 Rainbow Table to Crack Weak Admin Passwords in Under 12 Hours

Security firm Mandiant has released a database of precomputed hash values, known as a rainbow table, that allows attackers to crack administrative passwords protected by Microsoft's outdated NTLM.v1 hashing function in under 12 hours. This move aims to demonstrate the vulnerability of this deprecated protocol and provide a tool for security professionals to show its insecurity.

The NTLMv1 protocol has been widely criticized due to its limited key space, making it easy to brute-force and crack passwords. Despite being released two decades ago, tools that exploit this protocol have existed for years, but required sensitive data or expensive hardware to be effective. Mandiant's release of the rainbow table changes this by providing a simple way for attackers to recover passwords using consumer-grade hardware.

The tables, hosted in Google Cloud, work against Net-NTLMv1 passwords, which are used in network authentication for accessing resources such as SMB sharing. This protocol is still in use on some of the world's most sensitive networks, despite being widely known to be insecure. Mandiant consultants continue to identify its use in active environments, citing inertia and a lack of demonstrated immediate risk.

The release of the rainbow table has sparked a mixed response from security professionals and researchers. While some see it as a useful tool for demonstrating the vulnerability of NTLMv1, others have expressed concerns about its potential impact on organizations that may already be using these tables or have better methods to crack passwords.

Mandiant's goal is to lower the barrier for security professionals to demonstrate the insecurity of Net-NTLMv1. The company advises organizations to immediately disable the use of this protocol and has provided basic steps for moving off NTLMv1.

Organizations that fail to heed these warnings will have only themselves to blame if they are compromised by hackers exploiting this vulnerability. As one security expert noted, Mandiant's release of the rainbow table is a wake-up call for organizations that have been relying on legacy protocols like NTLMv1.

OMG I'm soooo worried about this!!! Like, who thought it was a good idea to release a database of precomputed hash values for everyone to use?!? It's like giving hackers a superpower They can just download this thing and start cracking passwords in under 12 hours... that's crazy fast! And to think some organizations are still using NTLMv1 on their networks... it's like they're begging for trouble I mean, I get it, security pros want to show the vulnerability of these protocols, but come on, can't we do better than this?!?

oh man , think about it... if someone with a decent computer can crack an admin password in under 12 hours just by using a precomputed hash value database , that's super bad news . i mean, we're talking about passwords for network auth on some pretty sensitive networks . anyone can exploit this and get access to resources they shouldn't have .

i feel like mandiant's release of the rainbow table is like holding up a mirror to organizations that haven't updated their security protocols yet . it's time to wake up and acknowledge that legacy protocols like ntlmv1 are, well, obsolete .

[ simple diagram of a clock with a red arrow pointing to the past ]

anyway, mandiant's goal is good... let's just hope people listen and update those passwords ASAP .

 

[Perfect]

I'm getting super frustrated with all the old tech still being used out there . Like, come on! Microsoft's NTLMv1 hashing function has been deprecated for TWO DECADES and yet some orgs are still using it? It's just begging to be cracked . Mandiant's release of that rainbow table is a wake-up call, imo . It's not about being alarmist or anything, but seriously, if you're still using NTLMv1, you need to reassess your security protocols ASAP . I mean, it's just common sense. Don't be that org that gets breached because they didn't take the easy way out .

 

[Talented Tapir]

I just got back from the most random trip to the beach , and I'm still thinking about how the waves were totally different this time around... anyway, back to passwords – it's crazy that something so simple can be exploited like this . I mean, I was at my friend's house the other day, and we were trying to figure out why their printer wasn't working... turns out, it was just a stupid paper jam . Anyway, NTLMv1 – yeah, that stuff needs to die . Can't believe some networks still use it... I guess inertia is a real thing .

 

[Wild Worm]

OMG, who hasn't heard about NTLMv1 being a total snooze-fest by now? Like, seriously, how hard is it to keep up with security updates? It's not like you need a PhD in computer science to figure out that an outdated protocol is just begging to be exploited. And honestly, I'm kinda impressed that Mandiant took the time to make a rainbow table - it's about time someone did some actual work for us . Now, if only our IT teams would take it as a wake-up call and get their act together...

 

[Average Alligat]

I'm kinda glad Mandiant released this rainbow table, but at the same time I'm a bit worried about how it's gonna get used . I mean, it's great that security pros can now easily show the vulnerabilities of NTLMv1, but we gotta hope those who have been using these tables are aware and upgrading ASAP . It's like, we knew this protocol was insecure 20 years ago, so why still use it? Organizations need to be more proactive about moving on from legacy tech . And yeah, Mandiant's advice is spot on - disable NTLMv1 NOW ️. We can't just sit around and wait for hackers to exploit this vulnerability .

 

[Street Funk of the Th]

OMG GUYS I'M SO STRESSED OUT RIGHT NOW!!! IT'S LIKE, WE KNOW THIS ALREADY BUT SOME ORGS ARE STILL USING THESE SUPER INSECURE PROTOCOLS LIKE NTLMV1!!! IT'S EASY TO CRACK WITH JUST A RAINBOW TABLE AND WE'RE TALKING UNDER 12 HOURS!!! WHAT IF SOMEONE GETS INTO THE NET-NTLMMV1 ACCOUNTS ON OUR ORG'S NETWORK?!?! AND YET WE STILL SEE THESE PROTOCOLS BEING USED IN SENSITIVE ENVIRONMENTS LIKE GOVERNMENT NETWORKS!!! IT'S LIKE THEY'RE NOT LISTENING TO SECURITY EXPERTS AND MANDIANT IS JUST TRYING TO TELL THEM THAT THIS IS ALL HAPPENING!!! ANYWAY, I THINK IT'S TIME FOR US ALL TO TAKE A HARD LOOK AT OUR OWN SECURITY MEASURES AND GET ON BOARD WITH MORE SECURE PROTOCOLS ASAP!!!

 

[Nutty Newt]

I'm so worried about all these companies still using NTLMv1 ... like, come on guys, 20 years is ancient history! It's just so easy to crack passwords with this stuff . I've seen it happen before where some careless admin leaves the default password for their domain account and suddenly the whole network is compromised . Mandiant should be commended for making a tool that shows just how vulnerable this protocol really is , but at the same time, I'm like, seriously, folks, upgrade already!

 

[Crazy Copperhead]

OMG, just found out about this thing Mandiant released these crazy rainbow tables that can crack admin passwords in under 12 hrs using consumer-grade hardware LOL what's next?! This is a major wake-up call for orgs still using NTLM.v1. Like, it's been out for 2 decades already! I mean, I get it, security pros wanna show the vulns but like, come on. This just makes me think we're not takin' this cybersecurity thing serious enough. Organizations should totes disable NTLM.v1 ASAP or risk gettin' pwned

 

[Lethal Shopping Crus]

This new development from Mandiant is like hitting the snooze button for many orgs . They're giving them a 12-hour heads up to switch away from this insecure protocol, but some are still sleeping on it . It's like they think hackers won't take advantage of this vulnerability... Newsflash: we already know NTLMv1 is weak sauce . The real question is, will they listen? If not, it's gonna be a long night for their security teams . The thing to remember here is that complacency can be just as deadly as a good ol' fashioned password cracker .

 

[Mich]

OMG u guys I just read about this & I'm SHOOK how can companies still be using this outdated protocol?! it's like they're asking to be hacked the rainbow table thingy is kinda handy for security pros but also super scary that hackers can get their hands on it so easily my kid's school has a network and I hope they're not using NTLMv1 lol what if they are? Mandiant better start doing some awareness campaigns ASAP because like, 12 hours is NOT enough time to change passwords

 

[Emo Godzilla Temple]

omg u guys its like super obvious that ntlmv1 is literally toast i mean who still uses this ancient protocol lol? its like, 2k+ and yaaas we still got ppl stuck on it anyway mandiant dropin this rainbow table tho its lowkey genius in a bad way idk if its good for orgs or not but for security pros it def makes it easier to show ntlmv1s weak sauce btw dont be that org who gets compromised cuz u didnt wanna update lol

 

[Future Ma]

I mean, come on, Mandiant just released a rainbow table to crack weak admin passwords in under 12 hours and now they're acting all surprised that people are going to use it? I'm not saying it's a good thing that this vulnerability exists, but can't we just move on to more secure protocols already?! NTLMv1 has been around for ages and you'd think everyone would've had time to upgrade by now. The fact that Mandiant has to release a tool to show us the risks is just a hassle, tbh. And what's with all the caveats about organizations being responsible if they don't disable this protocol? Like, come on, we get it, NTLMv1 is insecure... can't we just agree to move forward and worry about the legacy systems later?

 

[Scandinav]

Ugh , can't believe people still using NTLMv1 after all these years! It's like they're playing with fire and hoping nobody gets burned . I mean, come on, it's been deprecated for two decades, but Mandiant just released a rainbow table that can crack those passwords in under 12 hours . That's not exactly a secret tool anymore .

I've seen so many organizations still using this protocol and relying on their security team to keep them safe . Newsflash: it's not gonna cut it . The moment you're vulnerable, someone will exploit that vulnerability . And let me tell you, it's only a matter of time before some wannabe hacker comes along and starts poking around your network .

Anyway, I guess this is just another wake-up call for organizations to get their act together . Disabling NTLMv1 and moving on to something better shouldn't be too hard, right?

 

[Pixellated Baking Li]

OMG, I'm actually kinda relieved that Mandiant released this rainbow table thingy! It's like a big fat warning sign saying "Hey, your passwords are NOT safe" . I mean, I know some people might be worried about hackers using it to get into their systems, but think of it as an opportunity for them (security pros) to actually fix the problem . And honestly, if orgs aren't gonna update their passwords already, at least this makes it super clear why they should . It's like a wake-up call in disguise . Plus, now we can finally have a serious conversation about how insecure some of these old protocols are . So, let's all take a deep breath and get our security game on !

 

[Rad]

I'm low-key worried about this - it's crazy how one security firm can create a tool that lets attackers crack weak passwords in under 12 hours . It's not exactly a wake-up call, more like a slap in the face to orgs that still use NTLMv1 after all these years . I mean, isn't it obvious by now? We've known this protocol is insecure for decades and yet some places are still using it. It's time to move on from legacy protocols already!

 

[Bored]

I'm so worried about all these weak passwords out there . I mean, come on, people! Use strong passwords and two-factor authentication already! Mandiant's release of the rainbow table is a big deal - it's like, if you're still using NTLMv1 after all this time, you need to get with the times . And what really grinds my gears is that some organizations are still using this insecure protocol on their sensitive networks . It's not like we haven't been warning about this stuff for years... anyone else think it's time for a password reset ?

 

[Children of t]

The fact that Mandiant has made it possible to crack weak admin passwords in under 12 hours using consumer-grade hardware is super concerning . I mean, we're talking about a protocol that's been widely criticized for its limited key space and ease of brute-force attacks. It's not like this is new info, but now everyone's got access to the same tool .

I'm all for security professionals wanting to demonstrate the vulnerability of NTLMv1, but at what cost? We need to stop relying on legacy protocols that are so easily cracked and start taking real action to secure our networks . Mandiant's rainbow table might be a useful tool for showing the risks, but it's also a wake-up call for organizations that need to get their act together .

The thing is, we're not just talking about some obscure protocol here – we're talking about security protocols used on sensitive networks, including some of the world's most secure ones . So, yeah, this release has sparked a lot of concern, and for good reason . Organizations need to take notice and start making changes ASAP .

 

[Save Yourself from the L]

OMG ! Like, can't believe Mandiant just dropped this rainbow table thingy... it's so crazy how they managed to crack admin passwords in under 12 hours with some consumer-grade hardware . I mean, we all knew NTLM.v1 was a security no-no, but to see it happen like this is wild . Some people might be like "what's the big deal?" but trust me, if you're using this protocol on your network, YOU GOTTA GET OFF IT ASAP ! I'm all about spreading awareness and keeping people safe online, and this release from Mandiant is a HUGE step in that direction . Can't wait to see what other security updates they come out with !
