Web Security for the Tech Impaired: Connecting to WiFi

We’ve all been at an airport or coffee shop and checked our phone to see that your internet connection is incredibly slow. You curse the heavens in frustration and then you notice that they offer free WiFi. “What fortuitous circumstances!” you think. You look on your phone for what networks are available around you and you see:
Starbucks
FREE_Starbucks
Public-Starbucks

Uh……. ok…… which one do you choose? They all seem to be owned by Starbucks so you go ahead and connect to the first one. After a few days you notice your credit card has some weird unauthorized charges. “That’s odd” you think, “maybe it had something to do with that free WiFi I connected to….

While connecting to free WiFi networks seems like a good idea, it can be extremely dangerous. The danger is that it is incredibly easy to setup your own WiFi network at these locations. An attacker buys a relatively inexpensive tool which he can set up at any location and give it any name they like. Victims will think that the network is legitimate and connect to the attackers WiFi network. After connecting, the attacker can now see the traffic going between the victim and the internet, effectively spying on all the traffic going back and forth between the victim and any site they are browsing. This is what is known as a ‘man in the middle’ attack.

So how do you protect yourself from being a victim?
1) I always like to turn off WiFi if it’s not being used. This serves two purposes. It saves your battery which is always nice and it protects you from having your device connect to an undesirable WiFi network without you knowing it.

2) If you need to connect to a WiFi network confirm the name of the network with someone at the business. Often in airports there will be official signs with the networks name on them hung throughout. Smaller locations are tougher because attackers can make very convincing fake signs and sprinkle them throughout the business. In these cases I like to ask someone working there what the network name should be.

3) Never trust a WiFi network. I never do any banking, purchasing or sensitive transaction while connected to a public WiFi network. Save that for home or a WiFi network you know and trust. It’s just not worth it. If you absolutely have to, make sure the site is using “https” in front of the URL.

4) If you do connect to a public network, use your phone or computer’s ‘forget network’ feature after you’re done. Your phone will have a list of all networks it’s connected to in the past somewhere within your WiFi settings panel. If WiFi is enabled your phone will automatically connect to these networks. To prevent it from doing that, always go into this settings and either long hold them or select the options menu and select ‘forget network’. This will prevent your phone from automatically connecting.

#HackerKast 40: OPM Breach, Sourcepoint, AdBlock Plus, NSA and AV software, Adobe Flash, Chrome Listens In via Computer Mic


Regards,

Hey Everybody! Welcome to our 40th HackerKast! Thanks for listening as always and lets get to the news!

Our first story to chat about this week was news bubbling up still about the recent OPM breach. This time, the news outlets are latching on to the fact that data encryption wouldn’t have helped them in this case. Jeremiah poses the question “Is this true? And if so, when does it protect you?” Robert and I go back and forth a bit about layers of protection and how encryption in this regard will only help with host layer issues. Some other ideas come up about data restrictions being put upon the database queries as they are taking place so that the crown jewels can’t be stolen via one simple hole.

Next, we moved on to a story Robert was drooling over about Google’s new pet project company, Sourcepoint, which exists to stop ad blocking. Apparently they originally launched to detect when ads are being modified, which was apparently an issue in the SEO world. However, the way the tech worked, monitoring the DOM allowed them to pivot a bit to detect ad blocking by users. This could be leveraged to stop the user from blocking, or could alert the user and ask really nicely for them not to block ads which could be harming some sites’ revenue. We then all made the comparison here that the modern age of ads looks a lot like the age of Anti-Virus with the whole cat and mouse game of writing signatures to catch which domains are serving ads.

On the topic of ad blockers, AdBlock Plus added a feature which would allow enterprise level IT admins to roll out the browser plugin to an entire company. We need to remind people that AdBlock Plus also is the ad blocker on the market that will allow ads that pay them to be whitelisted. This means the more computers their software is on, the more they can ask to be whitelisted.

Jer couldn’t wait to talk about this next story about the NSA reverse engineering AV software. He starts by giving us all a quick history lesson of his interest in AV being the ironic attack vector for hackers to get into systems. The current story is about a recently leaked Snowden document that outlined an NSA program which reversed AV software — including Kaspersky — to utilize it to track and monitor users. Not a good week for Kaspersky coming off the heels of Duqu 2.0 recently.

Our transition from one virus propagator to another here brings us to our next story: Adobe Flash. The initial story that made our list was Brian Krebs talking about detoxing from Flash for 30 days with it completely removed from his system. He gives some good advice about disabling flash, removing it altogether, or enabling click to play. While editing this story though, he had to add a note at the top which proved his point that the day it was published there was an out-of-band Zero-Day patch Adobe released this week. The Zero-Day was identified by some ridiculously named FireEye report of an attack being used in Singapore from a Chinese hacking group they call APT3. We have a good conversation about Flash and what a huge target it’s been and what a nightmare it is to get users to update.

The icing on our cake to go back to ragging on Google is a story that hit the privacy community this week of Chrome listening to you via your computer microphone. For some reason, the initial group they decided to test this with was Chromium users on Debian who noticed the silent update start to log this audio information. Apparently there is some legitimate purpose behind this, like saying “Hi Google” to your computer and giving it voice commands. They then send this audio to their servers to do analysis to improve their service. They double, triple, super duper promise they aren’t logging it or sharing the audio. We went off on a tangent here on how awful of an idea this is. I brought up how we’ve got a nice diagram from the NSA showing how they strip HTTPS at the Google layer to monitor users so it really doesn’t matter if they log or store it if the NSA can just snoop on the wire there. Who knows where this is going to go, but now you might have an always on microphone in your house.

#HackerKast 39: MLB Astros Hacked By Cardinals, Duqu 2.0, More Ad Blocking News and RIP Microsoft Ask Toolbar

Hey everybody and welcome to another week in Internet Security. Robert and I were trying our best to stay above water with Tropical Storm Bill hitting Southern Texas while Jeremiah was making us jealous with his palm trees and blue skies in Hawaii. I’ll remember that one Jer…

Back on topic, our first story was some shameless self promotion of Jeremiah talking about eSecurityPlanet doing a story on the Top 20 Influencers in the security industry. He happened to make the list himself but there are a lot of other notable names on there with links to lots of good research going on. Notably for me was our friend Dan Goodin who is a journalist that we link to a lot in HackerKast and is the first to cover many security news stories. Kudos to all.

Next, some news broke right before we started recording that was super interesting about some MLB teams getting into the hacking space. Turns out a former employee of the Houston Astros who left and now works for the St. Louis Cardinals never had his access turned off and was leveraging his old credentials. The Astros have some high-end scouting data that was put together with some cutting edge “Moneyball” style metrics that the Cardinals wanted their hands on. The FBI has been brought in to investigate this, how far this incident went and to prosecute those at fault.

We moved on from the baseball hack and into a security company admitting getting hacked with Kaspersky coming out and talking about Duqu 2.0. Robert touched on this and what made it interesting was that Duqu is almost certainly developed by a nation state due to some evidence reported on about it. The other major interesting tidbit about this is Duqu at some point, stole a valid Foxconn SSL certificate which allowed the malware to bypass a lot of first lines of defense. By using a valid cert, Duqu wouldn’t trip many of the alarms that normal malware would have upon entering a network. Robert also mentioned that in light of this, Foxconn should probably be doing some forensics and incident response into figuring out how their certificate was stolen.

Couldn’t make it out of another HackerKast without talking about one of our favorite topics, ad blocking. There was an article this week in Wired which discusses the differences in ad blocking on desktop platforms and mobile devices. Since browser extensions have become so prevalent and are cutting into the wallets of certain advertisers, *cough*Google*cough, there is a movement towards pushing users to use specific apps for content that they’d like to digest. Robert’s discusses an example with CNN where it would push users to use the CNN mobile app where they control the content fully and there would be no such thing as ad blocking.

Staying on the ad topic, Microsoft put out a research paper about serving web ads locally from your own computer. Think of this as a super cache which would have some implications on bandwidth, load time, ad blocking, and some malware related consequences. The major motivation here is almost certainly avoiding ad blocking since the ads are not loading dynamically from the web. Jer made the joke of hoping that chmod 000 being a thing for that folder.

Lastly we finish off with a Dan Goodin story with a witty title of “Ding Dong, the witch is dead” referring to Microsoft finally bringing the hammer down on the Ask toolbar. Microsoft’s malware team and suite of software including Microsoft Security Essentials will now flag the Ask Toolbar, most notably bundled with Oracle products by default such as Java, as unwanted software. The criteria of this flagging is software that includes “unwanted behavior, delivery of unwanted advertising, and a loss of user’s privacy”. The other speculation we made was that this would save Microsoft millions of dollars in customer service calls of how to remove it from Internet Explorer from unsavvy users who accidentally installed it. We all smell lawsuits on the horizon and will be an interesting one to watch.

#HackerKast 38: Pulse tests .gov sites, China hacked US government, DuckDuckGo, NSA Quantum Insert attacks and Google finds Ad Blocking annoying

Hey All! Welcome to another HackerKast! I’m back whether you like it or not.

Gave a quick rundown of my Europe trip before jumping into the news and we started with one of my favorite stories we’ve covered in a while. This one was about a project called Pulse which grabbed every .gov site it could get its hands on and ran an SSL Labs tester on it (hat tip to the awesome Ivan Ristic). Pulse then takes all the results and puts them in a very nice sortable table that, with one click, reveals pages and pages of government agencies with “F” grade scores. An “F” basically means they are vulnerable in at least 1 way to a major SSL flaw like POODLE or Heartbleed. Jeremiah tied this in to another story of an order in the government that mandates all websites are to be compliant with up to date SSL/TLS standards in the next year and a half or risk being taken offline.

Next, the story we couldn’t avoid, it is being reported that hackers from China stole over 4 million records from our government’s personnel office network. These records detail tons of information about current and past government employees. Some of the scariest pieces of info stolen are the results of secret clearance data which dives deep into the personal lives of people applying for secret or above clearances. Speculations have been made theorizing that this could be used to blackmail and flip people into working for foreign entities.

After getting off on a tangent about all that, Robert talked about the next story of some new DuckDuckGo features. Seems they are adding a whole suite of crypto related search features that are pretty neat, including generating strong passwords, identifying hashing algorithms, hashing things for you, and last but not least, searching for known plaintext of hashes. If you have some hashed passwords from a dump that you got your hands on, you can type the hash into DuckDuckGo and ask it to search known previously cracked hashes to see if its on the list. Who needs your own rainbow table anyway?

Robert continues with a serious deep dive into a story about detecting the NSA’s complex Quantum Insert attacks. This topic has whole blog posts dedicated to itself if you’re interested in what it is and how the NSA is using it. It could be easy enough to create a piece of code to sit on your computer and look for anomalies in your packets consistent with this type of Insert attack to detect if you’re being MiTM’ed in this way.

The last complete tangent we went off on was about Ad Blocking which is a subject near and dear to our hearts. The story in question was detailing how popular Ad Blocking software is getting and how Google is feeling about this. A notable quote from Google’s CEO about this basically states that Ad Blocking is used to block “annoying” ads so in order to make it less popular is to make less annoying ads. We all got a laugh about how “annoying” malware, user tracking, loss of privacy, bandwidth usage, power consumption, etc. all are.

#HackerKast 37: More router hacking, StegoSploit, XSS Polyglot and Columbia Casualty Insurance refuses to pay Cottage Health

One more lonely week without Matt Johansen as Jeremiah and I have braved another HackerKast on our own. Thankfully we were comforted by some very interesting stories. Most of them were technical but one of them was around insurance.

First up was about router hacking – one of Jer and my favorite topics. It turns out someone has been automating intranet hacking using the browser to attack various different SOHO routers and firewalls. This is neat because it’s actually in the wild, being used. It attempts various passwords, and ultimately tries to re-write DNS or route users to another location. Pretty nasty. I had a brief conversation with NoScript’s author, Giorgio Maone who is considering writing Application Boundary Enforcement into a stand-alone plugin.

Then we talked about two stories, StegoSploit and something called XSS Polyglot. They’re different takes on the same issue. If you need to do some hosting of content on another domain for some reason (typically payloads) you can do so in an image or using Flash. Both are great articles and they both do a pretty good job of breaking CSP in certain implementations.

Lastly we talked about an insurance provider called Columbia Casualty Insurance who refuses to pay out Cottage Health due to lax security. Namely, Cottage Health allegedly failed to do the things their policy required of them. If you don’t do what you say you’re doing, it’s hard to see why they would be obligated to pay out. Either way, it’s an interesting case, and probably the first of many to come.

#HackerKast 36: Moose Router Worm, Adult Friend Finder male users hacked, Firefox and advertising, WHS Stats Report, and IRS Data Breach

It was just Jeremiah and me again today, as Matt is shamelessly galavanting around Europe at various security conferences (I think it’s safe to hate him for it, isn’t it?). But we had a ton of interesting stories this week to cover and didn’t have much time to do it.

The first up was the Moose Router Worm – similar to the Internet Census Project, it used default usernames and passwords to compromise remote routers. We don’t know how many routers were compromised but it was a lot, I’m sure. Jer seems to think that routers shouldn’t even have this feature at all – and I’m inclined to agree.

It was a bad week for Adult Friend Finder, but an even worse week for their users, who had user account data stolen and published on the Internet. The data dump was incomplete and only comprised about 300M worth of data. Also, interestingly enough, it seemed to contain only data from the male users, which implies that it’s probably more about who is most easily blackmailed and less about what the actual adversaries have.

Next up we discussed Firefox and their rather strange move to build an advertising platform into the browser. Their reasoning is complicated, but it seems to revolve around a mix of making money and doing right by their users – except I don’t recall a user ever asking for this. Meanwhile one of Mozilla’s own employees wrote up a great paper on how users with ad blocking and privacy protection can save up to 40% bandwidth and page load time on the top Alexa sites. Shortly after, that same employee promptly left the company under somewhat mysterious circumstances.

Then we covered the stats report. You’ll have to download it to see for yourself, but there are a great number of interesting findings in there. For instance it appears to refute the idea of a best practice. There just doesn’t seem to be any one security factor that will prevent people from being hackable. Maybe they work in some combination, but not in a vacuum. Check it out.

Lastly, we briefly touched on the IRS data breech (if you can call it that) where north of 100k people’s tax data were stolen. This is almost certainly the result of stealing user data through something like Zeus or other public places and combining data to attempt to log in as the user. Jer’s point couldn’t be more clear – Social Security Numbers aren’t a good password, stop using them. If you are, you’re site is hackable.

That’s it for the week, I hope you enjoyed it! We’ll be back next week. Rate, subscribe, and give us feedback on things you’d like us to cover.

WhiteHat Website Security Statistics Report: From Detection to Correction

While web security used to be a reactionary afterthought, it has evolved to become a necessity for organizations that wish to conduct online business safely. Companies have switched from playing defense to playing offense in a game that is still difficult to win. In an effort to change the game, WhiteHat Security has been publishing its Website Security Statistics Report since 2006 in the hope of helping organizations improve web security before they become victim to an attack.

After several editions, this is by far the most data rich, educational, insightful and useful application security report I have ever read. I may be biased, but I believe this report is unique: something special and different that is an essential read for application security professionals. In creating this report, I have learned more about what works and what doesn’t work than I have learned doing anything else in my many years of working in application security. I am extremely confident that our readers will appreciate what we have created for them.

In this year’s report, we examine the activities of real-world application security programs along with the most prevalent vulnerabilities based on data collected from more than 30,000 websites under WhiteHat Sentinel management. From there, we can then determine how many vulnerabilities get fixed, the average time it takes to fix them, and how every application security program can measurably improve. Our research provides insights into how organizations can better determine which security metric to improve upon.

We’ve learned that vulnerabilities are plentiful, that they stay open for weeks or months, and that typically only half get fixed. We have become adept at finding vulnerabilities. The next phase is to improve the remediation process. In order to keep up with the increase in vulnerabilities, we need to make the remediation process faster and easier. The amount of time companies are vulnerable to web attacks is much too long – an average of 193 days from the first notification. Increasing the rate at which these vulnerabilities are remediated is the only way to protect users.

The best way to lower the average number of vulnerabilities, speed up time-to-fix, and increase remediation rates is to feed vulnerability results back to development through established bug tracking or mitigation channels. This places application security at the forefront of development and minimizes the need for remediation further down the road. The goal is more secure software, not more security software.

For security to improve, organizations need to set aside the idea of ‘best practices’ and not stop at compliance controls. Multiple parts of the organization must determine which teams should be held accountable for their specific job function. Organizations that don’t hold specific teams accountable have an average remediation rate of 24% versus 33% for companies that do. When you empower those who are also accountable, the organization has a higher likelihood of being effective.

In this year’s edition, the WhiteHat Website Security Statistics Report drives home the point that we now have a very clear understanding of what vulnerabilities are out there. Based on that information, we must create a solid, measurable remediation program to remove those vulnerabilities and increase the safety and security of the web.

Logjam: Web Encryption Vulnerability

A team of researchers has released details of a new attack called “Logjam.” This attack, like FREAK, enables a man-in-the-middle attacker to downgrade the connection between the client and the server to an easier-to-break cipher. Many servers support these weaker ciphers, though there is no practical reason to support them. The solution is to simply not support any ciphers that are easy to break. In fact, the browser makers are doing that right now.

The offending ciphers, Export Diffie-Hellman ciphers, can be found in HTTPS, SSH, VPN, mail, and many other servers. This does not, however, mean that you are vulnerable, or that you need to panic. Exploiting this vulnerability requires man-in-the-middle and a high level of sophistication. The real risk is relatively low on this issue compared to Poodle or Heartbleed. You should simply test your TLS endpoints to ensure that they do not support any weak ciphers. If you took this step back when FREAK came out, you are likely already okay.

The specific ciphers to disable for this attack are DHE_EXPORT ciphers (or “EXP-EDH-” ciphers). But go ahead and disable all weak ciphers, while you’re at it.

All WhiteHat Sentinel dynamic testing services (BE, SE, PE, PL, Elite) now report the use of export ciphers as part of reporting on weak ciphers, and specifically call out the ciphers that are a concern for Logjam.

The research team that released the report has also set up a page to test your servers here: https://weakdh.org/sysadmin.html.

Remember that when you test a hostname, you are really testing the TLS endpoint for that connection, which may be a load balancer or firewall, and not your application server.

#HackerKast 34: SOHO Routers hacked, 3d printed ammo, Nazis & child porn, PayPal Remote Code Execution, Dubsmash 2, Twitter CSRF

Hey Everybody! We’re back from our 1 week break due to crazy schedules and even now we are without Jeremiah. Coconuts don’t make great WiFi antennae or something.

Started this episode talking about some Vendors who decided to do some weird, bad stuff this past week. In both stories it seems some security vendors were caught being naughty, starting with Tiversa. They are a security firm that decided it’d be a good idea to extort their own clients by finding a fake vulnerability and asking for money to fix this fake vulnerability. Then Tencent and Qihoo, two different Chinese AV Vendors, were both caught cheating on a certification test about how good their products were.

Moving away from shady vendors and on to shady home wireless routers. Not news to anybody, really: wifi routers you buy off the shelf aren’t quite state of the art when it comes to security. Hence, we see some sort of router hacking story pop up all the time. This time SOHO routers were targeted by the hacking group Anonymous, as per a report from Incapsula. It seems Anonymous saw a good opportunity to exploit these home routers and use them as a botnet, running their DDoS tool for fun and profit. The extremely 1337 H@x0r methodology being used here, which takes many years of cyber security experience and probably a CISSP to exploit, is a default username and password. Try to keep up here, the DEFAULT USERNAME AND PASSWORD out of the box was used to compromise MILLIONS of home routers and turn them into DDoS bots. I’ll just leave that there.

Next, Robert talked about some of the most ridiculous topics we’ve talked about on the podcast. He somehow related 3d printed ammunition to a story about Nazis and child pornography. You see, some court ruled somewhere that the file on the computer that can be used to 3d print bullets is now considered as munitions legally. In related(?) news, there was some Nazi war camp website that got hacked and got child pornography uploaded to it. When child porn is involved, the government immediately must confiscate the computers as evidence which essentially takes the website offline. Robert related the two by saying that you could also upload a 3d printer file which would have the same effect, now that a file can constitute illegal munitions.

In vulnerability disclosure news, PayPal was vulnerable to Remote Code Execution via a 3rd party library they were using. The Java Debug Wire Protocol using Shellifier was leaving port 8000 open on some Paypal servers, which allowed an attacker to gain access remotely — without authenticating — and execute commands. The part we don’t know yet is whether or how much PayPal paid the researcher who disclosed this to them. They’ve been known to pay big bounties in the past.

Robert then covered a fake mobile app called Dubsmash 2 that was uploaded to the Google Play store this week and got wildly popular. Apparently, Dubsmash is a popular app which allows you to lip sync to some songs — but the fraudulent sequel app wouldn’t be nearly as fun. What it did was immediately remove the “Dubsmash” part of the app and replace the icon with a mimic “Settings” icon. The moment a user clicked this icon, the app would generate thousands of pop-unders of porn sites and click on ads. The thought here was they are using this in a pay-per-click fraud scheme to generate earnings for the developer. 500,000 users downloaded the fake app to date.

Lastly, we talked about a CSRF vulnerability disclosed via HackerOne to Twitter about 11 months ago and recently disclosed publicly. This CSRF protection bypass was *very* creative and used a behavior in certain frameworks which treats commas as semicolons. This would allow an attacker to exploit a user by sending them a malicious link which would allow the attacker to use the CSRF token they stole on mobile.twitter.com. Really cool research that I’m glad eventually became public.

#HackerKast 32: WordPress Core XSS, Spoof Email Tanks Stock, Tesla Defacement via DNS Hack, 451 Status Code, MS15-034 Microsoft Vulnerability

Hey All! Thanks for checking out this week’s HackerKast! We’re all back and recovering from RSA and my feet still hurt.

Starting off with This Week In WordPress Sucks™, we’ve got a vulnerability in WordPress core this time. This is usually not the case as core has been gone over several times with a fine toothed comb, but some persistent XSS in core comment functionality popped up anyway. Also, as per usual, a few hundred plugins were vulnerable to an XSS that was found in two different frequently used functions that were poorly documented. The core issue were patched already but it is up to administrators of WordPress installs to race and get the patch installed.

Next, in silly things that affect the stock market news, Italy’s 2nd largest bank had a hoax email go out pretending to be the CEO resigning. Within moments, the stock takes a huge crash before coming back up after everyone realizes it was a hoax. We’ve seen this before a few times, notably the time Associated Press Twitter account was hacked and tweeted about a bomb at the White House which caused the entire stock market to take a dive for a few minutes. This all points to the fact that there are automated stock trading systems out there making decisions based off of social media and news information.

We had a little chat about the recent problem over at Tesla where their homepage was “defaced”. This wasn’t actually a defacement of any servers on their end but the attackers went after the recently popular low hanging fruit of DNS providers. Once the DNS provider was owned, the homepage was redirected along with any MX records allowing emails to be rerouted to the attackers. With this email rerouting in place, they then sent out some Twitter password reset emails which allowed them to take over the social media accounts. What Robert and I touched on at the end here is that Tesla was lucky that this was all for the lulz because that email rerouting, if done correctly, could’ve been silently MiTMing the company’s emails for some time before anybody noticed. Scary stuff relying on a DNS provider with that level of severity of compromise.

A new status code is being presented in the HTTP standard for the purposes of displaying a legally related block. Instead of just a 404, the browser would now present a 451 which would mean legally restricted due to any number of reasons. Most popularly this would show up for geolocation related blocks of content that tons of Netflix users are very aware of.

Lastly, MS-15-034, came out which was a Microsoft Buffer Overflow vulnerability in IIS servers. Of course Robert couldn’t help himself and wrote a snippet of exploit code. Then in This Week In RSnake Puts Something Dangerous Social Media™ he posted this code to Twitter for people to play with exploit in a remotely exploitable way. We’re toying with a possible demo we could do of this for you all but might take some tinkering to make it interesting.
