My fourth article in a series of six: Operational Security Part 4: Computer Network OPSEC is now available at Canadian Security Magazine.
A web proxy provides an easy way to change your IP address while surfing the Internet. They don’t require software or modification to your networking settings. You just enter a website address and the sites you visit through the proxy see an IP address belonging to the proxy rather than your IP address.
I am very cautious about using web proxies as you never know who actually operates it and what data they might collect as you use it. You also don’t know to whom they might give that data. On the other hand, I have found one that has a useful feature.
nroxy offers all the usual web proxy features plus something interesting–it offers the ability to change the user agent. For example, some web sites cannot be viewed properly using Firefox. Sometimes it is an old site that requires MS Internet Explorer (IE) or it may be a site designed for mobile devices. This proxy offers user agents typical of 5 mobile devices and a long list of browsers.
To get the information I need I am finding it necessary to switch user agents more often. Usually, I use the User Agent Switcher extension that adds a menu and a toolbar button to switch the user agent of a browser. It allows you to chose from three versions of IE or an iPhone. Selecting the iPhone user agent often reveals additional functionality on the site. The extension is available for Firefox and will run on any platform that this browser supports including Windows, OS X and Linux.
Now I have another option when I need to change the user agent and I get the additional proxy features as well.
Freenet is like BitTorrent with web sites. Freenet is an anonymous peer-to-peer data-sharing network where uploaded data is assigned a unique key then broken-up into small, encrypted chunks which are then scattered across multiple computers on the network.
When someone wants a document, photograph or some other data, they “fetch” it from the network using the unique key assigned to that data. The fetch requests get routed through intermediary computers that don’t house the requested data, This ensures that no single computer on the network knows the contents of any individual data file.
With the Freenet client running on your PC, you can use most Web browsers to browse files and websites (AKA freesites) on the Freenet. The client allows you to access the Freenet welcome page (http://127.0.0.1:8888/) using your normal browser. From this welcome page, you can move on to browse Freenet, chat on Freenet forums, and communicate with other Freenet users.
Freenet has a darknet mode (AKA friends-only mode) for maximum privacy. In darknet mode, you connect to Freenet through trusted associates with whom you exchange encryption keys, which makes it difficult for anyone to track your movements on Freenet or even that you’re using Freenet. Of course, funneling your Freenet access through a handful of trusted associates may create a traffic bottleneck that slows response times. To avoid this, get five or ten friends to join up with you so you can fetch Freenet websites and files at greater speed.
Don’t expect this to provide total anonymity if you are doing something that is illegal or a risk to national security. Freenet has been infiltrated by police agencies that have created their own Freenet nodes to deanonymize users. You can be certain that national intelligence agencies have done the same.
A Pew Research Poll indicates that college students are spending less time on Facebook and more on simplified instant messaging services like Snapchat, Instagram, WhatsApp and Yik-Yak. Campus safety officers haven’t caught up with this trend. They still check Facebook most consistently, followed by Twitter and Yik-Yak.
In my experience, very few organizations use social media threat alert software or employ a social media monitoring company. Everything that I have seen indicates that orgainsations that monitor social media for risk management usually monitor the wrong sites.
Recently, when working at a client sites, I’ve taken to occasionally using Windows to Go. This is Microsoft’s little-used secure workspace feature for Windows. It allows you to boot into a secure workspace located entirely on a USB key. This enables you to use Windows without relying on the operating system, applications, or storage on the host device. It creates a secure workspace on any machine that can boot from a USB drive without trusting the host machine. I have even devised a way to use a Virtual Machine (VM) in this workspace. Because the workspace doesn’t rely on the host operating system, the workspace on the USB drive isn’t at risk of compromise from a host machine and the VM protects the USB workspace. This saves me from constant use of my ‘Safe Mode on steroids’ or reinstalling Windows from a drive image on a client’s machine. However, it is too slow and requires too much effort to maintain. A similar live Linux USB seems to offer faster performance and it is easier to maintain the VM.
I wander through the nether regions of the Internet and Dark Net looking for data to support my clients’ causes. This exposes me to severe risks from the nasty creativity of Beelzebub’s demonic gangsters and hackers.
It seems that a Windows system only lasts about 1/2 hour before getting infected without some form of anti-virus (AV). I regularly boot a clean live Linux USB, and then scan for viruses. This is like Safe Mode on steroids. In most instances, I find something malicious missed by the typical AV programs. However, this is only a temporary measure.
I am migrating to Linux for Investigative Internet Research because very little Linux malware exists in the wild. I only need AV on the Linux file server (or an email server if I had one). I do this because an infected Windows computer may upload infected files or an uninfected one might access infected files on the Linux machine, which then allows it to infect other Windows systems. AV on the file server isn’t protecting the Linux system–it’s protecting the Windows computers from themselves. I recommend the paid version of ESET Antivirus and Security Software as it doesn’t try to upsell you on other services.
TrueCrypt, the ultimate encryption freeware, abruptly announced that the software is no longer secure after Microsoft ended support for Windows XP. It was the most popular application of its type and it was widely to communicate securely and encrypt sensitive files or folders. Currently, the TrueCrypt home page advocates moving to Microsoft BitLocker.
Unfortunately, in the Windows 10 Home edition, the full-disk BitLocker encryption must use a Microsoft account and the recovery key needed to decrypt your drive resides on Microsoft’s servers. With this arrangement, theoretically, a third party could decrypt your drives remotely. However, Windows 10 Pro doesn’t have this restriction: you can use BitLocker with a local account and keep your key out of the cloud.
Under such circumstances, users should stay away from both TrueCrypt and BitLocker and shift to some other free file encryption software.
Veracrypt entered market within months after Truecrypt died and seems to be the best of the alternatives. There are other free TrueCrypt alternatives like AESCrypt, FreeOTFE, and DiskCryptor. Here are the download sites for the alternatives:
The first of my 6 articles about maintaining operational security for the security intelligence function in the private sector is now online at Canadian Security Magazine.
An investigator can use LinkedIn, Facebook, and other sites to build a profile of someone’s personal and work life, but like so many things in life, this is both good and bad. What might happen if it is done to your business’s employees? How might this hurt your company? Most businesses do not think about this and if they do, they usually consider key executives to be most at risk. This is entirely wrong!
Operational security (OPSEC) is the lens through which to view this risk. View each employee in terms of what he knows and to what he has access. This will change your entire outlook.
The janitor has keys and is in the building alone. Security guards possess sensitive information. The secretary to the VP of Marketing knows when you will launch a new product. Are you starting to get the picture? This leaves the problem of how to analyse the content of sites like LinkedIn and Facebook.
For example, Facebook identifies your friends and family, and where they live. It knows your likes and dislikes. It knows your travel destinations. It knows posting habits and posts to which you will respond. All of this creates an OPSEC nightmare.
The Wolfram Alpha Facebook Report lets you see what information Facebook knows about you and your friends. It yields easy-to-understand charts, tables, and graphs in a personalized report.
This needs the account holder to log into Facebook before it will run, however, this will not stop an industrial spy, foreign agent, gangster, or terrorist. In certain dark corners of the Internet, hacking a social media account will cost about $350. Changing the privacy settings is a meagre deterrent. With the hacked account and the Wolfram Alpha Facebook Report, the crook or spy has everything he needs to plan the compromise of an employee.
LinkedIn & Spies
Using LinkedIn, researchers found the personal details of 27,000 intelligence officers that the researchers say are working on surveillance programs. They compiled the records into the ICWatch database, which is searchable by company, title, name, and location.
What might a skilled researcher find regarding your employees?
The biggest part of dealing with this OPSEC risk is recognising that it exists. The rest of the solution involves a combination of strict social media policies, non-disclosure agreements, conditions of employment, and employment contracts coupled with employee indoctrination and training.
The Great Google Escape
Google’s products are fast, intuitive and reliable–but they are not free. You pay Google with your identity, behaviour, habit, and preference information. Google then collates and analyses this data and sells it to advertisers and gives it to government and intelligence services. The longer Google does this, the more valuable the data becomes. This raises some very real privacy and security concerns for people who use Google.
There are solutions to this privacy and security issue. The first obvious solution is to avoid putting all your digital eggs in one basket. Use a different email and calendar provider. Use Firefox not Chrome as a browser. Use providers in Europe to take advantage of European Union privacy laws.
Sign in to your Google account and Use Google Takeout to export your data to a downloadable ZIP file from all the Google products. Getting out of Gmail is easy–getting out of Calendar and Contacts not so much. Google sets file standards for their calendar and address-book to make migration awkward. However, migrating to mailbox.org in Germany seems to go ahead without any real difficulty. It even allows you to encrypt your emails and other files before storing them on the server. Best of all they do not scan your data and try to monetize it. However, it costs €1 per month.
If you use the free Google Drive, consider using the Omnicloud from Germany’s Fraunhofer Institute, which allows you to encrypt all data locally before uploading it to the cloud.
Install a tracker blocker such as Ghostery and Self-Destructing Cookies (SDC) in Firefox to guard against browser cookies and use a search engine like Duck Duck Go which does not record your search history.
In my last article on this topic, I asked the following questions:
- Should you include a warning about following links in your reports?
- Should you include a warning about visiting URLs in reports?
- Should you remove the links?
My answer is yes to all these questions. The content at the linked sites may not only change–it might plant malicious code on any computers used to visit it. This is more common than most private investigators recognise or admit. My research computers are almost immune to this but most other people do not go to the extremes that I do to avoid malicious code.
I do not like sending Word documents to clients. I much prefer sending PDF files. Unfortunately, much of my work is part of larger projects and the Word file allows a client to incorporate my work into other documents.
Sending Word documents has many risks but doing so is unavoidable in many cases. This leaves the investigator in a tight spot if he does not warn the recipient about the risks associated with visiting the links in the report. In addition to written warnings at the start of all reports, I now remove all links using Ctrl+Shift+F9. After being duly warned, to go to his doom, the reader must do more than just click a link.
I now include the following warning under the heading of Security Warning.
Warning about visiting reported links and URLs
All Universal Resource Locators (URL) or hyperlinks (links) cited in this report only report where we found data. We do not attest to the safety or security of any internet site or URL. Nor do we evaluate the security implications of visiting any URL.
Do not visit any cited URL or link without understanding the security risk of doing so. We only report the content associated with links, URLs, and Internet sites. You may compromise the security of your computer system and network by visiting URLs or links in this report.
If I recognise a site as an attack site or one that includes dubious code, I do report it, however, I have never had a request from a client that we evaluate the security risks of the sites from which I collect data. If I received such a request, I would turn away the job, as I do not have the expert staff to perform such complicated work.
Maintaining privacy during online research is as important as avoiding malicious code. Privacy begins with properly configuring the browser and installing the best oddons (for Firefox) such as HTTPS Everywhere and Self-Destructing Cookies (SDC).
This is a moderately complicated addon that requires the user to understand browser settings and how the browser handles cookies. Reading the addon documentation is required.
A recent study indicates that a two day interruption of key business functions could cost your business $3M. As most businesses are in urban areas, you could face much worse. One of my clients is located in Ferguson, Missouri and they have had weeks of disruption.
If your company is to continue operations during an upheaval, then the people who do the work must have the skills and resources needed to get through each workday. This requires a common-sense approach to urban survival planning for your employees rather than trying to create urban survivalists who grow an acre of food, raise goats, and live in underground bunkers, or worse having an entirely unprepared workforce. As most of your workforce probably lives in an urban setting, this bears serious consideration.
After researching this topic for several years I have come to the conclusion that you can’t train all your employees. You must select key people and train them and then make every reasonable effort to retain them. This may require a change in the corporate culture. It will certainly require looking beyond the next quarterly results.
Unfortunately, most business owners are risk-takers. They will see a major urban upheaval as an unlikely event. They will take the risk that during their tenure the event will not occur. This characteristic also explains many business failures, data breaches and large scale fraud events.
Business leaders need to understand their risk-taking behaviour. Without this risk-taking the business wouldn’t exist. Unfortunately, this same risk-taking may also destroy the business. Does your business have a risk committee of the board and does it consider this risk? Many businesses have an audit committee and compensation committee, why did so many abandon the practice of having a risk committee?
The full board has overall responsibility for risk oversight and this mirrors board responsibility for overseeing strategy. When an audit committee takes responsibility for risk management, the result is usually, in my experience, unfocused and inept. They do not have the skills and knowledge needed to evaluate all the business and operational risks faced by the enterprise. Audit committees often obscure the transparency needed for effective risk management and risk oversight by authorising such things as off-balance sheet transactions.
A separate risk committee of the board is not a one-size fits-all solution, but companies facing rapid changes in the business environment and emerging risks such as new technologies and security threats, should have a risk committee. Deteriorating urban infrastructure, poor city governments, inept policing, IT security, and other factors that affect business operations in our degenerating urban conditions certainly advocates the creation of a proper risk committee with business continuity on its agenda. The committee usually requires independent directors with specialised knowledge and experience with the critical risks facing the enterprise.
