Bingham County Idaho taken down by ransomware

Another County has been taken down by ransomware. The ransom demand here is $25-$30k via Bitcoin or Western union.

“Every department in the county is affected in some way,” “Phone systems, computer systems, everything. Some departments are handwriting documents.”  says Bingham County Commissioner Whitney Manwaring.

The IT staff thought the infection had been cleaned up, but a redundant, backup server was infected again, leading to the county going offline. “We had all kinds of firewalls in place to prevent these kinds of things from happening,” Manwaring told EastIdahoNews.com. “To prevent this from happening again there will likely be several more firewalls and more training for staff using county computers.”

More firewalls? Really? I’m not sure if this was misquoted by the press, or if the County Commish was just not familiar with the terms, but firewalls do very little to stop ransomware. Perhaps they are going to do a better job segmenting the network, and the staff training is a good idea though.

Trend Micro Ransomware File Decryptor Covers a Decent Number of Strains

While not perfect, this is a nice little tool to have in the toolbox just in case. I haven’t tried it personally, but it is said to decrypt files infected from the list below. Keep in mind there are some issues with certain strains, such as CryptXXX V3 and CERBER, so be sure to read the instructions and notes before proceeding. Hopefully you will never need this, but if you do, good luck.

Erich’s “What in the (cyber security) world is going on?” 02-16-17 edition

So, I will unabashedly admit to failing miserably at making my weekly post the last couple of weeks. I’ve been traveling and webinaring and otherwise buried in stuff. Oh, and I was abducted by aliens. yeah, that’s it… aliens. Either way, my bad.

Careless Licking Gets a Nasty Ransomware Phishing Infection

Yeah, I totally took this headline from my employer. It was just too good to pass up. What happened is Licking County Ohio got hit by ransomware that took down about 1,000 machines and completely shut down the town government. The best quote I’ve seen for a while came from that when County Auditor Mike Smith commented: “Apparently, our clock still works”. Ouch!

 

Polish banks hit by malware sent through hacked financial regulator

Well, some smooth slick soul managed to upload malware to the Polish financial regular’s website which resulted in infections in some Polish banks. Not a good thing, not at all. Just goes to show, be cautious even when dealing with “trusted” sources.

 

There is a fake Netflix app that is ransomware

Trying to steal Netflix? It may cost you. Just pay the $8mo for crying out loud.

 

New campaign spreading ransomware and another trojan simultaneously

Because Locky doesn’t suck enough as it is, this campaign is also downloading a click-fraud trojan so they can make a few bucks on the side. Shameless.

 

Mirai is spreading via Windows malware

They have started spreading this via windows trojans as they work to build the largest, most terrifying IoT botnet ever known to man. When fridges revolt, nobody is safe!

 

Arby’s got breached

More than 350,000 credit and debit cards could be at risk after Arby’s POS systems were found to be malware laden. I’d say more, but I have no beef with them. (<- you see what I did there, right?)

 

Soda machines take down a university

A gaggle of  infected IoT devices, including vending machines, caused a lot of havoc at an unnamed university by flooding the DNS server with seafood-related lookups. Obviously something was fishy, so they took action and tracked it down.

 

That’s all I have this week. I’m going to work on doing more mini posts based on things I see during the week, so subscribe and you will get those notifications. Thanks

FUD or Fact? Is ransomware and social engineering really that big of a threat?

We hear the stories almost daily, we see the headlines in the news, but how worried should we be?

The answer really is, it depends. Today I have seen a few headlines including this whopper: “New ransomware could poison your town’s water supply if you don’t pay up“. Sounds very scary, and the idea is, however it is important to understand that this is based on a Proof of Concept (PoC) attack demonstrated at RSA. Is it possible that this can occur, I suppose it is, but the real question is if it is likely. The answer is, not right now. This makes it FUD, or “Fear, Uncertainty and Doubt”. There is a big difference between showing a PoC and doing it in the wild, so you can sleep well tonight.

but…

This is where it get’s a bit spooky. It is possible, and if the researchers that did this are thinking about it, you can bet our enemies and the bad guys just out for a big payout, are too. So research like this is important, but let’s not start stocking up on bottled water just yet.

What is the real threat RIGHT NOW?

The current threats deal more with making fast money and wreaking havoc on organizations by locking them out of records and data that is required to do business. Even that threat is expanding though as hackers are working to innovate. Before we see water supplies threatened, expect to see more and more attacks where the bad guys are threatening to, or actually publicly releasing, sensitive information. Imagine if your organizations “secret sauce” or proprietary information was made public. How much did it cost you to develop that, and how much of a competitive advantage would be lost if that happened? Take KFC’s “Secret Recipe” for example. Rumor is, it is guarded by eunuch Ninja cyborgs… or something like that.

The other real threat is CEO Fraud (aka BEC) and W2 scams that are happening right now. Just yesterday I spoke with an individual that signed up for our training because they sent all of their employees W2’s to some scammers. They were surprised to learn that they are not alone. Manatee County, FL (in my own back yard) was a victim, as was Argyle School District in Texas. Even Snapchat got caught in the crosshairs last year. This is real, this is in the wild, and it is happening to organizations of every size in every industry.

So, what do you about it?

The number 1 way to counter these attacks is through user training because the number 1 attack vector is via email phishing. You train your folks and phish them with non-malicious payloads and links. This way they get used to spotting these phishing emails before something real hits. Technical controls are just not reliable enough to catch and stop these targeted attacks, but making your users a “Human Firewall” is.

The number 2 thing is to have good backups. This really only matters for ransomware because once you send money or W2 info, backups won’t help. For those cases, number 2 is to have a plan to deal with it. Developing this plan will help you react quickly and help you develop policies to avoid these attacks (e.g. ALWAYS talk to the requestor on the phone BEFORE sending money or sensitive info). All should agree on this policy, and they will if you have trained them on the threats. Also, know who your local law enforcement contacts are, and how to contact them. Having a PR firm and/or lawyer in mind is also a good idea.

So, keep an eye on the new developments, but don’t get dragged in to the FUD. Focus on the real, current threats and you will do more to protect yourself than by chasing the possible (but not likely) ghosts of things to come.

So, You Are a Tech Manager Now…

** I want to start by saying that this is nowhere near a comprehensive list of things that can help you better manage, but simply a sharing of my personal experience and meant to help people step back and think about things a bit. **

 

So, now you’re a manager. You got that promotion that you probably either dreaded or worked very hard for. The question is, what now? Your whole career you’ve been a tech guy and now all of a sudden you’re a manager. First thing to remember is, don’t panic! (and perhaps carry a towel just in case)

While this can be a very spooky time, it’s also a great step in your career. You are going to have to look at things a little differently though. For one, instead of waiting for somebody to tell you what to do, you’re going to have to do the telling. That means now, all of a sudden, you are responsible for figuring out what needs to be done and assigning someone to the task. This may be new to you, but if you keep a cool head, it’s not that bad.  Remember that when you’re in management, the responsibility falls to you. You can delegate the work, but you are still responsible for the results.

 

Budgets

Being in management means looking at the big picture. You need to understand what it really cost per unit of XYZ, and you are going to need to start thinking about how much available labor you have versus how much you need to spend. It’s like budgeting with money, only with time instead.

Something to remember here is that unlike money, where a dollar is worth a dollar, labor varies in its value. Some folks are 85% efficient, others hover around 12%, some can even cause an efficiency/oxygen deficit by dragging others down (<- we all know that person, right?). Labor is generally referred to in a unit of measure called an FTE (Full Time Equivalent) which we consider to be a body working 40 hours per week. Don’t ever try to calculate projects based on straight FTEs though as this can result in much wailing and gnashing of teeth. You have to remember that just because a person is burning oxygen for 40 hours a week, they are not producing 40 hours worth of work. On the flip side, sometimes a person can be working on 2 things at once that overlap, so you have to consider that. For example, if it takes 2 hours to image a workstation, you can figure that much of that time can be spent doing something else while data copies, so it may only take .5 FTEs (30 minutes of actual labor) to do the job.

 

When it comes to financial planning, if you are going to have a budget or be a part of budget planning, learn about the difference between CAPEX and OPEX. Understand that in the technical word, a lot of CAPEX also requires significant OPEX. Likewise, you can move some CAPEX expenses to OPEX, for example by moving to that cloud thingie that is so popular with you youngsters.

 

Language

Another hurdle you may face is a different language used by leadership. They tend to speaking dollarese where we speak in techenese. In a truly cruel irony of the universe, these two languages have very little in common, and those words that are similar in pronunciation, mean polar opposite things. This can lead to anything from minor misunderstandings to World Wars.  To get a handle on this I recommend you spend a little time with some online management courses, maybe somewhere like Lynda.com, that can help you understand management basics and semantics.

 

Personnel 

This can be truly difficult if you were promoted from within the ranks. You may be dealing with folks that are jealous that they did not get the promotion, folks that were peers that you did not get along with, or even the feeling that you “sold out” to management. Regardless, you have to change the relationship. This doesn’t mean you can’t be friends, but what that means will probably need to change how the friendship operates or is perceived. The days of partying after work with the team, sleeping in the parking garage and coming to work to hear stories that start with, “I can’t believe you did that!” are over. If that’s what you want, resign your leadership role now.

 

The best advice I can give when it comes to becoming a manager is to be humble, but firm. You are there to help the people you manage succeed and grow, and make the business a success. This is not about power, it’s not about bossing people around, it’s not about you, it’s about leading. That means getting your hands dirty as well and not just giving all the garbage jobs to the team. On the flip side, that does not mean you should do everything yourself. You have to allow others to do new things so they can grow, but don’t try to use them as your personal slaves. This may take some practice, but if you are honest with your team and humble about your role, people tend to respond well. You may have some folks push boundaries, this is normal as they figure out where your limits are. Don’t take this personally, listen to their suggestions, consider the argument, but remain firm in your decisions unless there is a compelling reason to change.

 

There are other things you may not have had to do, such as performance reviews for your old team members. This gets a little weird when you are managing people that you used to be peers with. It may not be easy, but this is one place where you really earn the title of manager. You may find yourself reviewing a person that you don’t like personally. Set the personal issues aside and judge them on the job requirements. It’s not always easy to do, but just because they shared that embarrassing picture from the Christmas party after a few too many eggnogs, it doesn’t mean they aren’t great at the job. You need to be honest about it and fair to everyone. Don’t be afraid to say, “Tom, we haven’t always got along, but you are a great here.”

 

Check Your Pride at the Door

Embrace feedback from your leadership and your team as well. Be open to criticism and be willing to learn from it. You are doing something new and uncomfortable and you will make some mistakes along the way. Mistakes are OK if you own the goof up, learn from it and don’t repeat it. Apply this to your team members as well.

 

Dress Code

I decided to add this after just having lunch with a friend. You might need to dress differently. Embrace it, love it, live it and SUIT UP!  😀

 

 

 

TL;DR

You are responsible for people now, and you will need to act like it. Embrace the personal and professional growth, get serious about things and enjoy seeing your team grow. It will grow on you, and one of the most rewarding things I have ever experienced is watching a person I led excel in their career and personal life.

 

 

 

Ransomware Infection Causes Loss of 8 Years Of Police Department Evidence

This is what we in the business call, “Not good”.

This was the  “OSIRIS” variant of Locky and looked for about $4k in ransom. According to one article, the chief said. “Our automatic backup started after the infection, so it just backed up infected files” which sounds more like replication than backups. It could also be a gross misconfiguration of the backups, either way, the data is gone.

The press release states that this is the result of a phishing email, which is very typical of this sort of thing.

Erich’s “What in the (cyber security) world is going on?” 01-26-17 edition

Lots of new stuff happening this week in the ransomware side of the house. In addition, you still need to be watching for W2 scams as they are starting to get reported. Having said that, here is my wrap up from the last week.

 

Facebook users hit with “You are in this video?” malware scam

Scammers are always looking for ways to get you to click on things. This one can prey on your fear of stupid things you may or may not have done on camera. Not saying this would get to me, but there might still be a video of me singing, “Any man of mine” during a tequila-fuel karaoke session a number of years ago. We all have that moment, right? Even if you don’t care to admit it, we are curious about what we may be in, and the scammers are using this to get to you click on malicious links, in this case phishing for credentials. Be careful folks.

 

Android Ransomware Locks Phone and Asks for Credit Card Number

Fortinet researcher Kai Lu, discovered this new threat. It appears to be targeting only Russian-speaking users, but it demands a HUGE ransom of about $9100 (545,000 Russian rubles) via credit card. I’m going to take a quick look in my crystal ball and say that I don’t expect this to actually work. You can buy a LOT of phones for $9100, and would you trust them with your credit card number? Yeah, no. Who knows though, perhaps it’s demonstrating a proof of concept.

 

Xiongmai messed up again, exposing installer passwords for a bunch of DVRs

Xionmai’s 2017 list of superuser passwords for certain DVRs was found on a LinkedIn page. This list is designed only for CCTV installers to access customer installations and is essentially a one-time pad or per-day superuser password for their DVR service. It appears to only impact versions sold in China, but it’s representative of the security practices of the org.

 

The St. Louis Public Library got hit by ransomware

They didn’t pay, but it messed things up for a couple of days. I can’t imagine the tension in the libraries over the couple of days this was going on. Hell hath no fury like a librarian slightly annoyed!

 

 

Delaware Blue Cross Blue Shield customer records got hit with ransomware

19,000 records were impacted. Because it’s healthcare, it’s considered a breach by the HHS. Not a fun thing. Reading between the lines, I would have to guess that the data was not encrypted when the ransomware hit, otherwise they could argue the breach classification down.

 

Houston, we have a problem… Data breach reported at Houston area Popeye’s

Popeye’s got, well… popped. Malware was found on computer systems at seven Houston area locations. It looks like it was there between May 5, 2016 and August 18, 2016.

 

New Satan Ransomware available through RaaS.

 A security researcher, Xylitol, discovered a new Ransomware as a Service, or RaaS, called Satan. This is a profit-sharing type of ransomware, kind of like a bad lawyer in the fact that if you don’t win, you don’t pay. RaaS developers take a 30% cut, and the scales slides down from there based on number of infections. RaaS means that scammers don’t have to have many skills to spread this sort of ransomware. We will start seeing a lot more of this moving forward.

 

Everyone’s least favorite ransomware is back and testing new infection tactics

One new Locky campaign is being called ‘Double Zipped Locky’ where the idea is to hide their malicious payload in a Zip file within a Zip file, hoping that the victim will think they’re opening a document. It also drops the Kovter Trojan which remains on the infected system and is used to run click-fraud and malvertising campaigns.

The second one is an email posing as a failed bank transaction with a .rar file containing a malicious Javascript file that downloads Locky and installs it.

 

USB Sticks Could Infect Your Network With New Spora Ransomware Worm

There is some interesting new info out about Spora. This ransomware offers an option of future immunity (for a fee), does not need a C&C server so blocking outbound communication doesn’t help, but the new stuff is, it adds the ‘hidden’ attribute to files and folders on the desktop, the root of USB drives and the system drive. These files and folders are now hidden by the standard folder options. It then makes Windows shortcuts with the same name and icon as the hidden files and folders. The .LNK files open the original file while also executing the malware and the worm. Pretty tricky.

It looks like Spora is the variant that hit a nursing school recently.  An instructors files were unreadable on home PC, so he brought them in on a USB drive to try it on a work machine. It did not end well.

 

Argyle School District Employees Hit with W2 Scam Data Breach

A school district in Argyle, TX got hit with a W2 scam that looked like it came from the District Superintendent. The email requested the 2016 W-2 information for all employees of the district and the employee sent it. This really happens folks, and now all of these people are at risk for fraudulently filed tax returns and identity theft. We need to spread the word about this, especially this time of year.

There is a new spam campaign spreading Sage 2.0 ransomware 

Sage 2.0 is demanding a $2000.00 ransom and is being spread by the RIG and Sundown exploit kits. This is also exfiltrating the data hidden inside a .png image by  steganography. I have been saying that I expect to see more strains doing data exfiltration, and this is an example of that.

Stay safe out there folks!

W2 Scams are Happening Folks!

If you have been to any of my talks and/or read many of my posts, you know that I have been preaching heavily about W2 scams this time of year. Scammers are hitting up folks with spear phishing attacks asking for W2’s. these look legit and appear to be coming from a person high up in the food chain. I have seen this personally and only the training my people had, and my open door policy, saved our bacon.

This is what just happened in Argyle, Texas:

http://www.nbcdfw.com/news/local/Argyle-ISD-Employees-Hit-with-Data-Breach-411337825.html

“District leaders said Wednesday an employee got a “phishing” email that appeared to be from the district superintendent.

That email asked for the 2016 W-2 information for all employees of the district. The employee complied with the email, attaching and emailing all W-2 information.”

I have spoken with FBI Special Agents that tell me that they have seen tax returns filed within 2-3 days from an event like this. Don’t be that guy/gal that let’s all of your employees lose their PII like this. Teach your people about the threat ASAP!
