From the HITME: Port 3131 “Gameframe” Scans

We’ve been watching some interesting scans primarily hitting our HITME sensors in Asia for the last couple of weeks. The connection occurs on port 3131/TCP and contains the following request:

GET http://gameframe.net/headers HTTP/1.1
User-Agent: Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.10
Host: gameframe.net
Accept-Encoding: deflate, gzip
Proxy-Connection: Keep-Alive
Accept-Language: en-gb,en;q=0.5
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
Pragma: no-cache
Cache-Control: no-cache

The scans we have seen seem to be originating primarily from Europe.

Have you seen similar scans and probes on this port? If so, please share with us in comments or via Twitter (@lbhuston). 

In the meantime, it is worth checking your application logs if you have any custom applications deployed on this port, particularly exposed to the Internet. While we don’t see anything indicating an attack, review of anything exposed for errors or follow on attack traffic is suggested (it’s usually a good idea anyway). 

Thanks for reading! 

 

What is HPSS? :: The Console

This article builds on the What is HPSS? Series. The original overview article is here

The HoneyPoint Security Server Console is the “brain” of the HoneyPoint product platform. It is the central component responsible for getting alert data from the sensors, tracking and maintaining the alert data, presenting it to the user and safely passing the essential alert data on to the automated plugins or other systems in the security event chain.


HoneyPointConsoleRole

The Console is a GUI application that includes a built-in database engine for tracking Alert Data state and to empower reporting and analysis over time. Alert Data from the sensors are sent to the Console over TCP and the data is encrypted. The Console application runs on Windows, Linux and OS X. 

 

Once the Console receives Alert Data from the sensors, it parses it to validate that the data is good and checks to see what actions it should take based on the alerting configuration, assigned admins list, ignored hosts lists, and other trust rules in place. 

It then presents the alert data to the appropriate mechanisms, alerting users, passing the desired elements of the alert data to syslog/event log on the Console system for upstream processing by SEIMs or other event tools. The Console also passes certain event data as determined by the configuration into the “plugins mechanism”. 

 

The plugins then execute the desired operations on the data, easily allowing the security team to further extend reporting to custom event handlers or perform automated responses. This flexible solution empowers the security team to integrate HoneyPoint Security Server fully into whatever technology platform/response process they desire or have in place.

 

Reporting from the Console is very simple. The included reporting engine can create a wide variety of canned reports in either CSV or HTML format, ensuing that the data in the HoneyPoint system is easy to use. Additionally, other reporting tools like Crystal Reports or the like, or even languages like PERL, Python or Ruby, can easily attach to the Console database to create whatever types of custom reports you desire.

 

All in all, HoneyPoint Security Server was designed to make it easy to use and yet flexible enough for the most demanding and mature infosec teams. The console interface is friendly, functional and easily understandable. Most teams require less than a 30 minute walk through before they are off and running with the basic detection power HoneyPoint provides. When they get comfortable with the system, they quickly master the plugins meta-language and are soon automating large groups of detection and response tasks.

 

To learn more about HoneyPoint Security Server or to get a demo, please contact us. We would be happy to walk you through the product and discuss how it might fit into your environment. There is even a free for personal use “Community Edition” available to get you started or to let you experience the power, ease and flexibility of the platform yourself. Just give us a call to learn more about HoneyPoint Security Server Console. You’ll be glad you did! 


What is this HoneyPoint Thing Anyway?

Launched in 2006, initially as a distributed honey pot product, HoneyPoint Security Server (HPSS) has grown well beyond the initial concept. Today HPSS is a platform of components woven into a tightly integrated, fully capable, extremely flexible threat detection product. Organizations around the world are using it as a means of early detection of internal and external attackers, malware outbreaks and signs of users poking around where they shouldn’t be. Mature organizations have leveraged the product as a means of deterring attacks through automated black holing of scanning hosts on their perimeter, embedded detective controls inside their web applications to cut off users violating their terms of service and gather real world threat metrics to feed back into their mature risk management initiatives.

 

In the world of ICS/SCADA, HoneyPoint has found a quickly growing set of fans. HPSS can be deployed in a completely passive way that has no chance of interfering with critical operations, yet still brings incredible detection capability and vision into even the most sensitive of networks. ICS/SCADA environments have traditionally embraced the honeypot ideal, coining the term “canary” for these tools, but never before have they had such an easy to use, distributable, centrally monitored honeypot capability like HoneyPoint brings to the table.

 

Over the next few months, we will be deep diving into each of the HPSS components, but for now, as a high-level overview, here is a quick and dirty explanation of each of them:

 

  • HPSS Console – This is the central “brain” of the product. Designed as an easy to use GUI application, it receives the alerts detected by the sensor components and presents them to the user for analysis. It includes the “plugin” capability which allows for additional reporting and security automation based on the event data detected. The Console provides for “point and click” easy integration with SEIM products for clients who have deeper back-end data aggregation systems in place.
  • HoneyPoint Agent – This is the original HoneyPoint detection capability. Agent creates “fake services” on the network that have no real use other than detection. Since the services aren’t real, any interaction with them is “suspicious at best and malicious at worst”. Agent is capable of emulating a great variety of services and is completely user configurable. Agent runs on Windows, Linux and OS X. 
  • Wasp – Wasp is HoneyPoint’s hybrid client for Windows systems. It offers many of the port dilation features of Agent, but layers on top of that a whitelisting detection mechanism, file change detection for key files and some simple heuristics to identify the most common signs of intrusion. Tiny footprint, immense flexibility, self tuning whitelisting and no interference with operations make it an excellent choice for critical infrastructure use.
  • HoneyPoint Web – This is a completely emulated web environment with a mock up of applications that the organization uses. The entire environment is “fake” and studded with detection mechanisms that capture and measure attacker behavior, intent and capability. It might seem to be a new version of a banking application “accidentally” exposed to the Internet, or a replica of an HMI or maybe a login portal for Sharepoint/VPN or some other mechanism. What it really is is a detection mechanism for the good guys. Completely customized, able to detect the difference between a human attacker and most malware, it offers organizations a deeper, sneakier way to detect illicit behavior and measure the attacker attention various attack surfaces receive.
  • HoneyElements – Embeddable HTML and Javascript objects that can be added to new or existing real web applications, these HoneyPoints extend detection into the layers of the application itself. Integrates well with automated response and attacker black holing defenses to stop attackers and those engaging in undesired behaviors in real time.
  • HoneyBees – These work with Agent to simulate users authenticating to emulated services with plain text credentials. Organizations use this combination of tools to detect sniffing attacks and other attempts to harvest credentials off the wire or from network monitoring systems. 
  • HoneyPoint Trojans – Trojans are “fake” documents, applications or archives that appear to be real, but are actually detection mechanisms. For example, they might appear to be a PDF of some acquisition plans, while in reality they are armed with code to alert the security team when they have been opened or tampered with. Trojans use many of the same tactics as attackers, but instead of infection as a goal, they provide for detection and alerting.
  • HoneyPoint Handler – The Handler is a mechanism for getting external events into the HoneyPoint data ecosystem. Organizations often use the handler to receive events generated by custom nuance detection scripts. For example, a script might routinely check for new files in a directory or new files that contain the call base64decode(). When the script identifies a new file, the script can send an alert to the Handler, which will create a standard HoneyPoint alert from the script’s data and send it to the Console for easy and standardized security event management.
  • HoneyPoint Decoy Appliances – This is a set of hardened Linux powered devices that serve as an appliance for other components, usually Agent and Web. The appliances are available in three physical form factors (a rack mountable server, a mini-desktop, and a field deployable power substation solid state system) and/or a set of virtual appliances for most common virtualization platforms.
  • HoneyPoint Proxy – Lastly, this component is designed to act as an alerting data aggregator to simplify firewall ACLs that might be deployed between DMZ segments, enclaves or other network segments. The proxy can receive events from HoneyPoints and send them on to the Console without the need to expose the Console to each individual HoneyPoint. This makes managing global and highly distributed deployments significantly easier.

 

To learn more about these components and how they can be leveraged to give your organization new, flexible and deep detection capabilities, give us a call. Our engineers would be glad to discuss the technical capabilities and an account executive would be happy to work with you to create a HoneyPoint deployment that meets your needs AND your budget. At MicroSolved, we are passionate about information security and HoneyPoint Security Server is just another that way it shows!

What Is Your Browser Leaking?

Today in my tweet stream, someone pointed out this site and I wanted to blog about it. The site is called stayinvisible.com and offers a quick view of some of the data that is available to a web site or an attacker who can lure someone to a website. 

The site displays a dump of a variety of common data that you might not be aware of that is leaking from your browser. There are also tips for hardening your browser settings and operating system against some of the methods used to dump the data. 

If nothing else, it might just provide an “ah ha” moment for folks not used to the information security space. Give it a try and let us know what you think of it. 

We have no association with the site, its content or the folks who run it. We just thought it was interesting. Your paranoia may vary. 🙂

Port 9100/TCP Probes

We have been seeing probes to port 9100/TCP in the HITME for a while and decided to check out some of the activity and post about it, so others could know what is going on there.

The connections come from a few sources, often universities, and don’t seem to be anything more than misconfigurations of devices in their environment. The connections that come in on port 9100 often contain the “@PJL INFO PRODINFO” strings, which are apparently tied to the HP Printer Job Language (PJL). Basically, the command is supposed to dump out identifying data from the printer and return it to the user. This data includes a variety of configuration data and other details about the device. You can find an example here

The port 9100 connections usually coincide with a connection to port 80/TCP on the same host. This port 80 connection looks something like this (with IP address info in the x.x.x.x string): 

“GET / HTTP/1.1\nAccept-Encoding: identity\nHost: x.x.x.x\nConnection: close\nUser-Agent: Python-urllib/2.7\n\n”

Now this is a little interesting. It is likely meant to be a validation probe that the printer device’s embedded web server is online and that the device is operational. BUT, the “Python-urllib/2.7” made us suspicious. Perhaps this isn’t a usual printer request?

A little Google searching pretty quickly shows that HP’s implementation of CUPS, that is the unix printing mechanism, strongly leverages this Python library.  So, that might not make it suspicious as most folks might think. 

So, we did the next thing in our bag of tricks, and returned valid connections from HoneyPoint on those ports. Our waiting finally came to fruition and lo and behold, we got more connections of the same nature. This time though, we also got a print job for the “printer” to print. What did we get? Spam, of course. Printer spam. An ad to buy some stuff, that needless to say, we don’t really need. 🙂

So, what are those port 9100 probes? What is the basis behind that “@PJL INFO PRODINFO” in your logs? Nothing more than spam attempts to waste your paper, ink/toner and time. Hey, it could have been worse, right? 🙂

Obviously, turning off port 9100/TCP from the Internet will help prevent this stuff from coming into your organization. It looks like a few malware folks have added this capability to their spyware/adware routines as well, so if you have 9100 blocked from the Internet and see printer spam coming in, track the print jobs back to a workstation if possible and do the turn and burn routine. Let us know if you have any questions or issues, and we will keep our ears and eyes open on port 9100 traffic and drop some more info if we see anything that looks wormy or the like. 

MSI ongoing assessment customers will note that port 9100 signatures are routinely tested and you would be notified of any illicit behaviors found during your assessments.

PS – There have been some “worm” like behaviors on port 9100 in the past, including a couple of pieces of printer malware. We didn’t see it in this case, but we know it’s out there…Here is an example of some of what may be lurking in your printer…

Terminal Services Attack Reductions Redux

Last week, we published a post about the high frequency of probes, scans and attacks against exposed Windows Terminal Services from the Internet. Many folks commented on Twitter to me about some of the things that can be done to minimize the risk of these exposures. As we indicated in the previous post, the best suggestions are to eliminate them altogether by placing Terminal Services exposures behind VPN connections or through the implementation of tokens/multi-factor authentication. 

Another idea is to implement specific firewall rules that block access to all but a specific set of IP addresses (such as the home IP address range of your admins or that of a specific jump host, etc.) This can go a long way to minimizing the frequency of interaction with the attack surfaces by random attacker tools, probes and scans. It also raises the bar slightly for more focused attackers by forcing them to target specific systems (where you can deploy increased monitoring).

In addition, a new tool for auditing the configuration of Terminal Services implementations came to our attention. This tool, called “rdp-sec-check”, was written by Portcullis Security and is available to the public. Our testing of the tool showed it to be quite useful in determining the configuration of exposed Terminal Services and in creating a path for hardening them wherever deployed. (Keep in mind, it is likely useful to harden the Terminal Services implementations internally to critical systems as well…)

Note that we particularly loved that the tool could be used REMOTELY. This makes it useful to audit multiple customer implementations, as well as to check RDP exposures during penetration testing engagements. 

Thanks to Portcullis for making this tool available. Hopefully between this tool to harden your deployments and our advice to minimize the exposures, we can all drive down some of the compromises and breaches that result from poor RDP implementations.

If you would like to create some threat metrics for what port 3389 Terminal Services exposures might look like for your organization, get in touch and we can discuss either metrics from the HITME or how to use HoneyPoint to gather such metrics for yourself

PS – Special thanks to @SecRunner for pointing out that many cloud hosting providers make Terminal Server available with default configurations when provisioning cloud systems in an ad-hoc manner. This is likely a HUGE cause for concern and may be what is keeping scans and probes for 3389/TCP so active, particularly amongst cloud-hosted HITME end points.

PSS – We also thought you might enjoy seeing a sample of the videos that show entry level attackers exactly how to crack weak passwords via Terminal Services using tools easily available on the Internet. These kinds of videos are common for low hanging fruit attack vectors. This video was randomly pulled from the Twitter stream with a search. We did not make it and are not responsible for its content. It may not be safe for work (NSFW), depending on your organization’s policies. 

 

Yandex.ru Indexing Crawler Issues

The yandex.ru crawler is an indexing application that spiders hosts and puts the results into the yandex.ru search engine. Like Google, Bing and other search engines, the system searches out new contents on the web continually and adds the content to the search engine database. Usually, these types of activities cause little issues for those whose sites are being indexed, and in fact, over the years an etiquette system based on rules placed in the robots.txt file of a web site has emerged.

Robots.txt files provide a rule set for search engine behaviors. They indicate what areas of a site a crawler may index and what sections of the site are to be avoided. Usually this is used to protect overly dynamic areas of the site where a crawler could encounter a variety of problems or inputs that can have either bandwidth or application issues for either the crawler, the web host or both. 

Sadly, many web crawlers and index bots do not honor the rules of robots.txt. Nor do attackers who are indexing your site for a variety of attack reasons. Given the impacts that some of these indexing tools can have on bandwidth, CPU use or database connectivity, other options for blocking them are sometimes sought. In particular, there are a lot of complaints about yandex.ru and their aggressive parsing, application interaction and deep site inspection techniques. They clearly have been identified as a search engine that does not seem to respect the honor system of robots.txt. A Google search for “yandex.ru ignores robots.txt” will show you a wide variety of complaints.

In our monitoring of the HITME traffic, we have observed many deep crawls by yandex.ru from a variety of IP ranges. In the majority of them, they either never requested the robots.txt file at all, or they simply ignored the contents of the file altogether. In fact, some of our HITME web applications have experienced the same high traffic cost concerns that other parts of the web community have been complaining about. In a couple of cases, the cost for supporting the scans of yandex.ru represent some 30+% of the total web traffic observed by the HITME end point. From our standpoint, that’s a pain in the pocketbook and in our attention span, to continually parse their alert traffic out of our metrics.

Techniques for blocking yandex.ru more forcibly than robots.txt have emerged. You can learn about some of them by searching “blocking yandex.ru”. The easiest and what has proven to be an effective way, is to use .htaccess rules. We’ve also had some more modest success with forcibly returning redirects to requests with known url parameters associated with yandex.ru, along with some level of success by blocking specific IPs associated with them via an ignore rule in HoneyPoint.

If you are battling yandex.ru crawling and want to get some additional help, drop us a comment or get in touch via Twitter (@lbhuston, @microsolved). You can also give an account representative a call to arrange for a more technical discussion. We hope this post helps some folks who are suffering increased bandwidth use or problems with their sites/apps due to this and other indexing crawler issues. Until next time, stay safe out there!

CSO Online Interview

Our founder & CEO, Brent Huston (@lbhuston) just had a quick interview with CSO Online about the Gauss malware. Look for discussions with Brent later today or tomorrow on the CSO site. Our thanks to CSO Online for thinking of us!

Update 1: The article has been posted on CSO Online and you can find it here

Brent would also like to point out that doing the basics of information security, and doing them well, will help reduce some of the stomach churning, hand wringing and knee-jerk reactions to hyped up threats like these. “Applying the MSI 80/20 Rule of InfoSec throughout your organization will really give folks better results than trying to manage a constant flow of patches, updates. hot fixes and signature tuning.” Huston said.

Malware Alert: Will You Lose Your Internet Access On Monday?

We’re always keeping our eyes and ears open when it comes to malware. If you’ve not heard of this report before now, it would be good to check your computer to see if it has been infected with a nasty piece of malware whose creators were finally caught and shut down by the FBI late in 2011.

From AllThingsD:

Next week, the Internet connections of about a quarter-million people will stop working because years ago their computers became infected with malware.

The malware is called DNSChanger, and it was the centerpiece of an Internet crime spree that came to an end last November when the FBI arrested and charged seven Eastern European men with 27 counts of wire fraud and other computer crimes. At one point, the DNSChanger malware had hijacked the Internet traffic of about a half-million PCs around the world by redirecting the victims’ Web browsers to Web sites owned by the criminals. They then cashed in on ads on those sites and racked up $14 million from the scheme. When the crackdown came, it was hailed as one of the biggest computer crime busts in history.
