This article addresses something that I have thought about, and had few ideas how to accomplish it. This article seems to have really great ideas. It was posted in three sections.
https://survivalblog.com/2022/03/03/silent-secure-communication-part-1-p-j/

Today, we see a growing vulnerability of our communications and how they impact our short term, and long-term lives. With hacking on the rise, electronic protection systems growing more and more complex, Social media nannies, and increased reliance on foreign components (that may have embedded spyware) …Americans are starting to wake up to the thought “maybe what I am saying isn’t private anymore”. You would be correct, and this would hint that a total loss of freedoms of speech and of security of your person has occurred or isn’t far away.

Our liberties are eroding around us in America, and whether we can change the trajectory that our governance is taking us…we can still have some fun playing games. Hey – the military has war games, we can have some too. Today I would like to challenge you all to a game of hide-and-seek. Let me explain.

If you want to hide information that only you and another pre-approved party are privy to, then you need to have ways to conceal that information or encrypt it. Since encryption is not my strongest talent, I will elaborate on the means and methods that allow someone to physically hide and transfer information in a secret manner to minimize the risk of interception. This article will give you means and methods that let you keep your communications obscure and separated from the typical channels. Let’s dive in.

Disclaimer: This article IN NO WAY advocates or encourages criminal activity!

THE DELIVERY
Here are a couple ways that you can be your own James Bond for communications transfers:

Option 1: The Dead Drop

Channel your inner spy with the old classic dead drop. A dead drop is a note, jump drive, CD, signal, etc. that is left in a location that another pre-informed person is supposed to find covertly. The point of a dead drop is that you can transfer a bunch of information where the actual transfer between parties is not witnessed and where both parties are not at the drop point at the same time. This is classic spy tradecraft that you probably read in novels or seen in movies.

Technology has really become tiny in this day and age, where 128+GB SIM-sized SD cards can be used cost-effectively and store a ton of information. You don’t need to use an electronic form; a written code can also be rolled up and deposited just as easily. Some very unique ways of performing dead drops (but not limited to) are as follows:

Inside a piece of chewed gum.

Wrap a Micro SD card or message in plastic wrap, sealed quickly with candle wax, then insert into the gum before you reach the drop area. All you have to do is pull the gum back out of your mouth and stick it under the park bench when you tie your shoe. Nobody is the wiser, and you look like the typical litterbug who got tired of the taste. Use a unique color gum (maybe use zebra stripe to pick a color) to stand out to the person picking up the gum.

TIP: Receiving person brings a tissue to pretend blowing nose, rests hand by bench edge and “lifts” the gum. Walks away with tissue and the drop.

Inside a piece of tissue:
Let’s face it, in the COVID era, who in their right mind would pick up a used tissue in a public place. Use at your own discretion…if you pick up the wrong one…jokes on you. However, this could play to your advantage…you could look like a hero volunteer picking up the gross mess! Just have a separate bag for when you have identified your target tissue (don’t want to sort that out back home!). NOTE – use a SMALL rock/weight obscurely rubber-banded inside the tissue to keep the wind from blowing it away (if it looks like a rubber-banded baggie of drugs, then it WILL be picked up prematurely).

Under a (matching color) tack:

This can be stuck to a fence top just next to the post (or anything wood). Most common folk don’t look up anymore let alone up and behind things, because they’re phone-obsessed. On top of door frames is another one, but be cautious who sees you place it, this is an unusual place to reach for to most people and will set off curiosity.

On the back of signs:
Best used with a magnet to hold it in place, but use adhesive or other means of quick deployment when using SD cards (a magnet may erase contents).

Tip: Superglue some felt on the attractive side of magnets. It gives the message something to cling to, and also helps reduce the “PING” noise as the magnet attracts to a holding surface.
Street signs and other metal poles make great items to “lean on when you stretch” (and deposit a drop) while jogging.

On the target’s vehicle:
Using a small pushpin-sized neodymium magnet, place the drop on the targets vehicle in a spot that they would see getting back into the car. Harder to use in winter, but still doable if the target knows to look for it. Protected areas are on the pillar right next to the driver side rear-view mirror (all the better if the targets car has a mirror that tilts inward, if they didn’t set it that way, they will certainly investigate when they notice it is moved), as well as the radiator grill (or fog light) openings (if metal) if they were looking for it.

On the back of an advertisement:

When the target will be by very shortly, or possibly within sight of the drop, an advertisement hung up on a storefront or common wall can be effective.

Take a “Help Wanted” sign and stick it to a wall where other similar public advertisements are placed. One with the little tear-away slips with a phone number are preferred, as people will take a tab versus the whole sheet most of the time.

Make the advertisement for something mundane that people may have interest in (but not a lot of interest), like a dog groomer or bathroom cleaning attendant.

Place the SD card or drop on the back of one of the middle tabs, offset from dead center, as people usually start pulling the strips from the end or dead in the middle.

The recipient will pick the tab with the drop later not long after the deposit (but don’t run over as soon as it is put up). It would be useful to mention that if this method is used, the recipient of the drop should rip the adjacent tab(s) halfway (making it useless to anyone that actually wants to pull a tab) to indicate that it was them that picked up the drop…and informing the depositor that the info has been received.

CAUTION: Do not use any of the following items for dead drops in public spaces, they will be picked up quickly by non-target people quickly in many cases:

  • Soda/pop cans
  • Random bricks or rocks that were not in the area prior
  • Lids of garbage cans or dumpsters (unless you are certain of the cleaning schedule)
  • Large trash or debris
  • Money of any kind
  • Food of any kind
DO USE: Your imagination! Look around at things that sit around for long periods of time that people do not think twice about. Then look for things that you can “contribute” to easily, and if anyone picked up would be ubiquitous.

Option 2: The drop message:

Similar to the dead drop, a message can be deposited by using cardboard, chalk, or spray paint. Often, this is just a visual indicator to the intended recipient that a nearby drop container is “loaded” with a fresh message. That way they won’t have to approach the drop container itself unless there is actually media available there for them to retrieve.

Here are a few examples:
A piece of paper duct-taped to the side of a building with one letter or number large enough to read from the car.
A chalk message on a wall or sidewalk.
A glass paint message on a storefront that you know is closed (after target reads, leave it cleaner than you found it).
A code, scribble, pattern, or image left at a determined location to give a clue to the recipient.

TIP 2: Servicing a dead drop should be nearly instantaneous. If someone notices you purposefully do it, then it will arouse suspicion. Practice like you would sleight of hand or anything else perception-based.

Option 3: The supervised quick delivery:

You can physically be present, a T-shirt with a message or sign can be displayed quickly and covertly when the appropriate person passes by. A one horn blast prior and two blasts post-reading by the recipient can let the sender know it was received. Sometimes it helps to pretend to wave to someone on the opposite side of the road to deflect suspicion (unless you and that person are the only two people there, then it works the opposite).
A big coat with letters on it can give abbreviated updates.
The goal is to submit a focused message to your recipient in a general manner, but only to display it briefly and confirm the receipt in person.

Let’s use a goofy example:
You and your co-worker bought 3,000 shares of a stock for a big tech startup, and your shares double since your purchase.
You get wind that the company has a lawsuit against it and will go bankrupt, but you can’t say anything because people will blame you for “insider trading”.
You assign the code for your shares as “mashed potatoes” and tell your co-worker it.
As your co-worker leaves work the next day and drives by the Starbucks near work, he sees you holding a big sign that says, “Eat your mashed potatoes!” This message is covert for “dump the stocks before they are worthless!” It might seem only slightly odd to someone driving by, but unless they knew that you mean stocks and not mashed potatoes, they wouldn’t have a clue.

Option 4: The live drop:

A person-to-person message drop can be performed as well, but it has the highest level of risk for someone to intercept or notice.

You have probably seen a live drop in movies where a briefcase changes hands in a crowded terminal or something, very observable for those paying attention and not overly discrete. It is absolutely critical that, if it can be avoided, the two individuals performing a live drop have no discernable connection with each other or readily identifiable groups! If known club member A passes by known club member B and has any kind of interaction, people in the know will put that together. However, if club member A has his grandma’s neighbor do the interaction, it may not be recognized quite as readily.

As I mentioned for the briefcase transfer, some drops need to be larger in size. The live drop is a certain way to guarantee that the target package has receipt by the target recipient – but it puts all the parties “at the scene”. Disguise is paramount…you may have to go to great lengths (like ‘borrow’ an Amazon van for the day) to pull off a large drop. [See further down in Caches for large item drops.] Suffice to say, make the item as common-place as possible to avoid detection of the transfer.
One idea for live drops is to plan ahead. For example, if the forecast is rain for the next three days, then arrange your drop outside. The target sits on a bench getting soaked. Informant walks by with an extra umbrella and graciously gives the umbrella to the soaked person. The drop is in the umbrella handle, the target then opens the umbrella, and gets up after a determined time after the informant leaves. It would be wise to come up with a handoff phrase that someone could not guess to ensure the correct target (if not known).

An example would be:
Informant: “You look a little wet!”
Target: “I’m alright, at least I’m drier than San Francisco” (SF reference says “I’m your person”)
Informant: “Here, I have an extra umbrella, stay dry and have a great day”

Another KGB-inspired method is to mark a cigarette with information that could be viewed immediately and then smoked to erase the info. The person walks by the informant and, using a codeword or phrase, asks to bum a smoke. They thank the informant as a normal person would, walk on and while lighting it, quickly views the important information (must be very short for the instantaneous review) and lights the whole end of the cigarette so as to burn away the information. This works great because you have to bring a smoke closer to your face to use it, so this is a natural motion. It also works at night because you have a flame to illuminate the message. If compromised, the informant could burn it prematurely – so it should be readily accessible for this reason. A single thick paintbrush bristle or toothpick tip works well to deposit letters/numbers in this manner. It has to be reasonably legible but not stand out like a billboard.

Option 5: The Cache:

Another way to transfer larger drops is by a cache. A cache is a concealed deposit of an item(s) of varying size, in a location that others would not readily find despite looking for it. A cache can be accessed one time, or multiple times by you or others. Here, I will discuss some rules of a successful cache:
1.) Location, location, location…Do not put a cache where people will be travelling all the time, unless your camouflage is impeccable, and you have an opportunity to place it “with purpose” (i.e construction worker). Remember: Securely planting and retrieving a drop get exponentially harder, the larger the drop becomes.
2.) Waterproof EVERYTHING. No matter how tight you seal it or how well you pack it, if it is left for long periods of time, hen it needs to be protected from moisture.
3.) Even if your location and camouflage is perfect, if the recipient cannot access the cache without suspicion it is not ideal. The only situation where this would be okay would be where the cache could be accessed quickly and never used again, or if a significant distraction is present (think firetruck coming through the coffee shop window, giving you enough time to quickly grab a bag stashed under the slushy machine). Even with a sufficient distraction, it is not guaranteed that nobody will witness accessing a cache.
4.) Camouflage is not optional…your cache should blend in like it was never there – or has always been there.
5.) Account for daylight/nighttime visibility differences. You do not want to hide a cache at night and then in the morning find out it looks like a group of woodchucks had an MMA battle. This is a critical detail for night operations.
a. Bring a thick bedsheet for dirt if digging, it is quieter than a tarp and nearly as durable. Pillowcases work for small amounts too and can fit in backpacks.
b. Bring a small hand rake to “rake out the grass” gently in turf areas after placement.
c. If possible, take a daytime picture you can reference while placing at night.
d. Work methodically in areas close to other people. Yes you want to place it and go, but nothing gives away a secret like a passerby hearing a shovel dig up a couple rocks at 1 AM.
6.) Use existing things that never get accessed. My favorite thing for an urban cache is an air conditioner. They are usually too heavy to try and move, too bulky to get away with it, and usually have ample room (even when operating) to hide larger items. Rooftop units are great because of the lack of foot traffic… add some tools and a uniform and you’re golden.
7.) By using maps and coded location, you can arrange a meeting, or indicate the location of a cache by way of map. This can be done for smaller items as well and is a useful technique for confusing average people from a location (remember that all but the vey best high-level encryption is crackable).

One very simple and effective tactic to transmit cache coordinates or arrange a meeting place without actually saying the coordinates, is to give an entirely unrelated location with a “x” feet or miles offset. Obviously, a small number would be miles, and a large number would be feet. Feet is most accurate and obviously works best in city terrain. Let’s say you live in Wilson NC, and we use the example “LH+1950-DEat”.
LH = Lowes Home improvement
1950 = distance away from the center of target [NOTE: You can use +/- interchangeably]
DEat = a place to eat that starts with the letter “D”

If you could procure a business card for Lowes building supply in Wilson NC, and write a “1950-DEat” on it, that would also give the coordinates…and most people will look at the “1950-DEat” as scribble. The same technique can be used on a non-satellite map by using the center of intersections or other landmarks. This coding is very simple, so extend to your comfort level of complexity.

This can be scaled up to a statewide application or even across the country, it just needs a way to discern what the sender implies as the target. You can use TR (intrastate) or TE (interstate) at the beginning of the instruction for clarity. This would avoid picking somewhere too local or too far away. Tucson Arizona could also be stated as “Nashville TNTR+1405iT” for example, to indicate the start city, state, intrastate, milage (use a little i), and starting letter of target locale. If multiple places do exist on the same circle, you can use an additional quantifier such as population or a familiar state animal (“Liz” for lizard would not be common in Utah or Montana, but certainly would be in Tucson).

TACTICS FOR DELIVERING A DROP
To place a drop without someone noticing that is what you are doing takes practice. You will need to practice like mentioned prior, as sleight of hand skill goes a long way to placing a drop. Gently setting a rolled-up newspaper into a trash can where another person picks it up just walking by might work when everyone’s head is buried in their phones, but certainly will get you found out if someone is observing you. Here are some cardinal rules for prioritizing drop tactics, if you cannot perform the former, adhere to the latter:

1.) No witnesses, large area.
a. Easy to conceal the drop, with a wide area to avoid a “brute force discovery”.
b. Allows a custom selection of drop locations, with minimal risk of being discovered (both parties).

2.) No witnesses, smaller area.
a. Easy to conceal the drop, but a higher risk of “brute force discovery” (think tearing apart a bedroom).
b. Smaller spaces only have so many places to hide something.
c. Camouflage must be heavily adhered to.
d. Being an are where witnesses are not usually present, using tactics like prying the edge of a duct vent or piece of wood molding can be used effectively. Think of a public bathroom, ever see things pried or ripped apart? This is often because criminals use this tactic too to hide drugs, so use discretion on the location that you choose.

3.) Witnesses, large area.
a. Drop must be tactfully placed, and reasonably camouflaged
b. Timing is important when depositing. If you place something when everyone is “busy” doing something (like during rush hour traffic or when a light changes on the crosswalk), they are much less likely to notice the placement action.
c. The more people, the more eyes…and hence the more tactfully the drop must be placed.
d. Larger area allows more space between you and others, use foliage and structure to your advantage to momentarily break the line of sight when making a drop.
e. Make your pause to deposit seem intentional. 15 minutes cloud gazing will calm the soul (and allow you to carefully place that USB drive under the lip of the bench you are sitting on).

4.) Witnesses, smaller area.
a. Drop must be very tactfully placed, and well camouflaged
b. Timing is important when depositing, but it is likely that you cannot hide something efficiently.
c. This scenario is where acting and “dressing the part” come into play. Hiding in plain sight is a must in this scenario, and both the drop and retrieve must be seamless.
d. Some tactful depositing roles could be:
d.i. A bricklayer filling in some broken mortar as a “building restoration volunteer” (and depositing a drop while doing the job.
d.ii. Tending to a semi-public space landscape (you can volunteer for these things anyway!) and placing drops in bushes during your pruning or under rocks when weeding.
d.iii. A window washer or graffiti cleaner that “accidentally” leaves a marked rag or brush behind. Sometime a good person will notice and return it immediately. Gauge your timing.
d.iv. Trash collectors, garbage attendants, trash pickers…all great opportunities to handle things nobody wants to touch and plan for your easy collection of drops.
e. In most cases, volunteering for things will open doors for you to deposit drops with practically zero suspicion. Depending on the viewability of the drop and retrieve, you will have to gauge your involvement with these type of activities as a requirement.

TIP: If for some reason you do retrieve the drop but notice that someone saw you, it may be in your best interest to destroy the drop and have it re-submitted. Depending on the nature of the drop, it could implicate you or worse get you killed. Gauge your surroundings very carefully.

PRO TIP: If you need a further look around to observe surroundings, don’t just look over your shoulder suspiciously like your head is a turret…do something natural. Look confused like you’re lost, get a tiny bit frustrated over something trivial like tripping on the curb, or even a touch angry like something didn’t go your way (rip a bag, drop a bottle, etc.). This is acting, if people believe you to be acting normal, you can hide something right under their noses…just don’t overdo it.

RETRIEVING A PHYSICAL DROP:

In order to gain access to the dropped information, you will have to remove all suspicion by the surrounding audience. If you look like a rich banker rifling through a garbage can, people will know you are looking for something…which is too “out of place”. As mentioned above for placing a drop, put yourself into the role of the person that needs to pick up the drop without suspicion. For instance, in areas with witnesses where stealth would be difficult:
A reflective vest with a garbage picker and bag walking around a park collecting garbage would not seem out of place. You would be helping clean your community and collecting your drop simultaneously…and nobody would think anything of it.
“Clean up” the edges of messy grout on a wall where a “careless brick layer” put too much on (referencing drop placement above).
While wearing a vest or uniform, inspecting a trashcan, and maybe replacing a bag (while collecting a drop) would be a reasonable action (wear gloves!).
Removal of posters from a common wall space (you will have to do some work to retrieve because you must play the part and do a good job to remove not just the target poster).
The key is that your lift of the drop should be fluid. Either nobody should see you do it, or everyone should see you do it as if you were supposed to do it (like garbage cleanup or similar).
When utilizing a drop point or cache multiple times, the risk of you or it being found goes up the more it is used. Having secure and non-repeatable access to the point is critical. You do not want a footpath in the snow or cow trail in the grass leading people to where you have been going.
Be mindful of touched surfaces…believe it or not, you can tell which brass knob gets used more than others around it just from the finish. Use this knowledge when touching/moving bricks, metal, or anything else that may leave a sign of wear or polish. If it looks used, other people will know to use it.

CONCLUSION
The most important point boils down to this…if everyone can know your business, how is it still your business. These methods are great ways to safeguard security and safety in uncertain times. In an age where electronic and phone surveillance has become commonplace, protecting the distribution and access to private information is even more important. Every aspect of what I have written can be adapted to the depth of your needs and is limited only by your creativity.

These skills and methods are just as effective at keeping a birthday party secret as they are from keeping the hypothetical gestapo from knowing your meeting location or list of attendees/members. If someone does not know how you are communicating and with whom, it is harder to intercept. Practice, and having friends and family in this mindset to expect the occasional code or drop, will give you the best shot at concealing communications. The situation in our country can change in an instant, and I would love for as many of you as possible to be informed about how to communicate securely with each other. Stay safe, and God bless!

Cameras are everywhere these days!
 
Cameras are everywhere these days!
Except sometimes when you need them! A friend had her car hit and run, and it seems she is the only person on her block with cameras. She wanted other views of the hit, but no one else could help her.
I watched a series on Netlix recently, Pieces of Her. There is a scene where someone runs into someone and in a matter of little time, person who is run into is fighting for his life. He was injected with something when the person ran into him.
 
I would probably go for "split electronic delivery".

Step one: Encrypt your message.
Step two: Break up the encrypted message into two parts. The first letter goes into file #1, the second into file #2, the third into file #1, the fourth into file #2, etc.
Step three: Deliver the two files via separate means: maybe email one, and use a dead drop of a microSD for the other. Either half, if intercepted, is useless.
Step four (done by the recipient): Recombine the two files by reversing the algorithm used to split them. In this example, interleave alternating letters.
Step five (recipient): Decrypt the recreated single file.

Both the senders computer and the recipients computer that are used for any of this encryption/splitting/recombining should be running their OS completely out of RAM memory - no hard disk or SSD or flash memory installed that could potentially save data. When you're done doing your work - unplug the computer so any remnants of data you entered are destroyed.

If anyone captures one of the files during transport they won't be able to decrypt it - even if they're the NSA - because they only have half/alternating letters. And since you're splitting things up after encrypting, they wouldn't be able to look at the half-file and make intelligent guesses about missing letters. An encrypted message looks like gibberish to the human eye. Every other letter of an encrypted message looks like gibberish too, and any attempts to decrypt it are doomed to fail.

This split delivery is probably overkill. But if you think you're being watched and sophisticated agencies want to decrypt your message, it's one additional safeguard.
 
I understand the Russians invading Ukraine are using unencrypted analog radios for communications. That would explain some of the difficulties they are having.
The chair is against the wall. The chair is against the wall.
I also understand that it is illegal to transmitted coded messages on Amateur Radio, FRS & GMRS frequencies.

Did you notice the coded message in this post?
