It’s THAT Bad

PATCH YOUR STUFF! Ms17-010, that fun little exploit leaked by the most recent ShadowBrokers dump, has been making the rounds in the worst way. WannaCry ransomware is everywhere. Get your backups in place. NOW! And don’t put them on the same network.

Countries around the globe have been hit by a massive ransomware attack  that has already earned 100 bitcoins. It started early this morning when hospitals in the UK were struck. There were confirmations that a telecom and businesses in Spain were also hit. 

Two hours ago, judging by the tweet storm, Russia, Israel, the US and 70 other countries were all infected.

Kevin Beaumont or @gossithedog on Twitter has recommended, in addition to patching your stuff, because Microsoft had this patch available before this happened and we know, WE KNOW, that attacker move this fast:

Make a group policy for the Windows firewall. Block SMB between all endpoint PCs. Limit between servers that need. So that way if you miss a patch in future ( but you won’t after today will you?) or if AV doesn’t work, then you can really make it harder for the ransomware to spread. Buying you time to control and contain.

Which prompts me to ask: How is your IR plan? Is it geared to cyber events like this? And oh yeah, do you have DR/ BCP cuz you sure as heck are going to need that ready to roll out. And – have you set up a policy on who says what for crisis communications? Because you really want to control how that happens too.

If you answered no to any of the above, just get on it now. Because you don:t know who is gonna get hit next on this round of rushin’ roulette.

Guess What I Get to Do Next?!

Some context on the ShadowBroker’s Dump

Photo by Tristan Schmurr, Cyberscoop Apr 21

A good friend of mine, with the handle @loneferret, shed some clarity on the massive dump of exploits two weeks back by the ShadowBrokers. I haven’t said my piece here but believe me I shared my thoughts online as things developed. And Double Pulsar, a backdoor implant, is just that gift that keeps on giving as countless systems appear to be infected. John Matherly of Shodan cited finding at least 45k as of April 21. Dan Gentler aka @viss describes it perfectly as “a loading dock for extra malware”. There is much to be said, but I quite liked the way my friend spun things, so without further ado …

Yet another MS17-010 blog post.
However, the more noise that is generated, the more people will update their systems.

About a week ago now, a bunch of exploits were leaked by a group calling themselves “Shadow Brokers”, or “ShadowBrokers”; both spellings are used it seems ¯\_(ツ)_/¯.
These exploits are serious stuff, as they affect almost every version of Windows, both professional and home (what you have at home most likely), as well as, server editions. There are Linux exploits as well but that’s for another post …

Barely a week has passed, and reports of ransomware being delivered using “Eternalblue” are popping up. Reports of systems being compromised by what we can only assume are “script-kiddies” have also surfaced.

Why keep reading? My goal here isn’t to give a technical lesson nor a course in exploitation, but to spread awareness. When these types of vulnerabilities & exploits are made public, havoc isn’t too far behind.

As a pen-tester the news of exploits originating from an NSA dump was exciting. It gives some insight on what sort of tools\exploits the notorious agency has, and ensures some level of job security for me (I know selfish). But what does this mean for the corporate user? What does this mean for the average user? In a nutshell if you haven’t installed the most recent security updates, you risk having your data stolen, deleted, or your hard drive encrypted and held for ransom.

I shall try and put this in perspective, in the most entertaining manner I can. So, sit back, grab your morning Irish coffee and step inside my time machine.

Back in 2003 a computer worm made its way through the Internet. This worm infected thousands of systems, both commercial and personal. It ravaged and pillaged everything it could lay its crummy little paws on. It was finally detected in 2008, and given the name “Conficker”. I remember 2008 well. At the time, I was a system administrator for an IT consulting firm & was called upon many times to stomp this little critter. This worm was good, well coded, and went undetected for 5 years! It merged so well with Windows, it really didn’t affect the system’s performance. It was also very good at reproducing itself… kinda like George Forman.

Why was it so successful? How did it manage to get into so many systems? It was a flaw in Windows, much like the flaw leveraged by the exploits in the “ShadowBrokers” dump. Essentially… it’s 2008 all over again. Which begs the question, how long did the NSA have this exploit? Also, were they the only ones? If it took 5 years to catch “Conficker”, one can assume this flaw (and exploit) has been around for at least the same amount time (give or take a year).

So, I beg you, please don’t fear the Windows update window.
Let it run… Embrace it, enjoy it, whisper sweet nothings into its ear.
Because if you don’t, you only have yourself to blame if your browser history ends up on pastebin.

A message from you friendly neighbourhood hacker @loneferret

Ps. This flaw, and others, were fixed back in March of 2017. This piece was written in April 2017.

It Really Was the Lazarus Group, in North Korea with SWIFT

swift

Last week, news broke that the US had linked North Korea to the theft of millions against the Federal Reserve in a series of bank heists involving the SWIFT messengering system.  I did a couple talks last year about banking insecurity as a fairy tale that misrepresented itself in the form of that trusted messengering system, SWIFT.  The deeper I delved, the scarier that fairy tale got. But from the start I had my suspicions about who was behind it and why. Why was a big factor because it ruled out the usual bank cyber crime suspects, aka Russia and Eastern Europe. This was too overt a move for a nation state to make right? Well, that depends which nation state you are.

And this was where my poli sci years kicked in.  I’ve always stood at that intersection of international relations and cybersecurity. It’s one heck of a vantage point. I do threat intel. Still pinching myself because I didn’t know this thing I love to do even existed a few years ago. But as I learn and grow in this field, what becomes increasingly clear is the need for context. That we have to take more than we surmise into account to really get the big picture. And we need the big picture to do this right. Otherwise we risk making the wrong call when we choose to play the attribution blame game, where the stakes are high and the consequences could level a lot more than the proverbial playing field.  So international relations, current affairs, global economy and history all need to be factored in. Then we have data with context and points that link, so we can see patterns.

Because for me this story was always so much more than just “hackers went after a billion but only got 81 million”.  Who was behind those hackers? Why Bank of Bangladesh? Who needed a billion badly enough to digitally “rob” a bank? I’ll admit I have my likely crew: Russia, China, North Korea.  In this case, Russia and China were too big to make this kind of a play and have to contend with the global condemnation.  That’s a headache they would rather avoid and neither needed a billion dollars that badly. However, North Korea was a different story: impoverished, starving, and whose wildcard of a leader answered to no one in his quest for nukes. As per a recent story in the Washington Post:

“North Korea has consistently been treated like a joke, but now the joke has nuclear weapons,” said John Park, director of the Korea Working Group at the Harvard Kennedy School. “If you deem Kim Jong Un to be irrational, then you’re implicitly underestimating him.”

Kim Jong Un may be crazy but he’s crazy like a fox.  Hence why the attacks were on banks where nobody would care. Because the truth is first world problems get the attention, not developing nations like those in South East Asia. And of course, security was lax, because the resources just weren’t there. Nor was the mindset.  Corruption and coercion get things done in many parts of the world. How do you factor those into NIST spreadsheets and security audits?

A colleague and I had a great brainstorming session on geopolitics and cybersecurity as we put the details together. His keen insights and my paranoia spun the needle to land on North Korea. We just didn’t have any proof.  Fast forward a few months later, though, and tracks were found in the butter. Remember what I said earlier about the importance of history, context and patterns? Key pieces of code harkened back to the attack on Sony, and some very crafty work by the Lazarus Group.  While it wasn’t a smoking gun, it certainly was substantive. After his work on decoding Stuxnet, I listen when Eric Chien of Symantec weighs in. He knew what he saw there and he called it.

sonyhackIn the realm of cyber criminals, The Lazarus Group are somewhat nebulous, hard to pin down, and known for their ability to die off and then resurrect themselves, hence their name.  They’ve been identified as operating out of North Korea. To me, that means North Korea gives them a safe haven in return for services rendered. They are the bag man for their host supplying “dirty deeds”, just not done dirt cheap.  Because nation states don’t do this stuff for themselves when they need to remain one step removed.  Let me state that things are no where near this simplistic, and yes, China factors into this as well.  But no surprise there given the long-standing partnership between China and North Korea.

lazarus_map_ENWhere does this lead? Well, I did allude to the possibility of global economic chaos being used in the games nations play, because it’s all about the power and money is just a means to that end. Now we have news reports saying how nation states have resorted to robbing banks, and what a terrifying prospect that is. According to Richard Ledgett, Deputy Director of the NSA, in a story by the Wall Street Journal:

“If that linkage is true, that means a nation-state is robbing banks. That is a big deal; it’s different,” he said on Tuesday during a panel discussion at the Aspen Institute.

Mhm. I have a lot more where that came from.
