Espionage and Secret Codes

Because sometimes, the dirtiest laundry is international intrigue.

Let’s be honest—when you think of laundry, you probably don’t imagine international espionage, war-time resistance, or Cold War tactics. You think of detergent, dryer sheets, and maybe how long you can ignore the wrinkle cycle before you cross into fashion crimes. But in the hidden pockets of history, laundry has played a surprisingly sneaky role—acting as camouflage, code, courier, and cover for some of the most daring espionage operations ever undertaken.

From World War II clotheslines signaling covert instructions to laundromats doubling as spy drop zones, let’s take a tumble into the dirty secret history of undercover laundry.

Signal in the Sheets: WWII and Resistance Clotheslines

During World War II, laundry wasn’t just a chore—it was a message board. Resistance fighters, especially throughout occupied Europe, used the humble clothesline as a means of silent communication. With heavily censored mail, radio lines under surveillance, and enemies on every corner, laundry became the language of survival.

Different combinations of clothing—hung in very specific patterns—acted as coded signals.

• A white handkerchief on the left? Meet tonight.
• A red blouse between two socks? Cancel the mission.
• A blanket folded in half over the line? Enemy patrol nearby.

Simple, visual, and easily explained as “just laundry,” these codes were hidden in plain sight. And if someone asked, you could always just say your toddler helped hang the wash.

One famous anecdote tells of a resistance group in France who used clothesline codes to coordinate British airdrops. A striped towel signaled the landing zone was clear; a black shirt warned of German troop activity. It worked for years—until someone mistakenly hung a rugby jersey and cost the Allies two crates of parachuted supplies and one very confused sheepdog.

Messages in the Machine: Spycraft and Laundry Tags

Even more cunning were the messages hidden within the laundry itself. Intelligence operatives used everything from ink-invisible laundry tickets to collar starch patterns that outlined maps when steamed.

A Soviet spy ring once embedded microfilm in buttons sewn onto dress shirts—easy to pass along at the local dry cleaner. In another case, British agents during the Cold War developed a method of writing coded messages using laundry starch that would only become visible when ironed.

Imagine the thrill of ironing a seemingly clean blouse only to discover it’s giving you directions to a safehouse.

In some laundries, “special” customers would bring in bundles wrapped a particular way. These bundles might contain laundry… or they might contain photographs, documents, or even codebooks sandwiched between sheets. The person receiving the drop knew just where to look.

The Laundress Who Listened

Throughout history, women working in laundry—especially those tasked with cleaning military uniforms—were often in close proximity to enemy conversations, gossip, and troop activity. And many of them took note.

In Nazi-occupied Poland, laundresses at German barracks were known to memorize names, ranks, and dates overheard while folding or scrubbing. They’d pass information along to resistance contacts by tucking notes into bundled laundry or whispering updates over back fences while “airing the linens.”

No one suspected the woman with the washboard. That was the magic.

These laundresses became the hidden eyes and ears of entire underground operations, risking their lives for scraps of overheard intel while pretending to care about stain removal.

Spies in the Spin Cycle: The Laundromat as a Front

Fast forward to the 1960s and ‘70s, and laundromats—those humming little storefronts full of clanking machines—became ideal for Cold War drop zones.

They had all the elements a spy could want:

• Background noise to cover conversations
• Little to no surveillance
• Constant movement of people
• And best of all—nobody ever really watches the guy folding towels

One well-documented CIA operation involved a safe house disguised as a 24-hour coin laundry in East Berlin. A small “employees only” closet in the back was rigged with listening devices, a two-way radio, and a hidden wall safe. The only thing more concealed than the equipment was the fact that the actual washing machines didn’t work—they were props.

Another spy used the laundromat excuse as a personal alibi. Every Thursday night, she’d leave the house with a full laundry basket, disappear for three hours, and return with a load of crisply folded cover stories. Her neighbors just assumed she was a clean freak. In reality, she was exchanging tapes and passing messages to a handler from the Czech intelligence service.

The Domestic Spy Routine

Of course, not all laundry-related espionage was formal. Sometimes, it was just a clever use of domestic routine.

Spies often used laundry day as cover for surveillance, check-ins, or escapes. No one questions the person walking to their car with a laundry basket. Nobody finds it suspicious if you say you’ll be gone for two hours doing wash. And if you’re followed? Just go to a real laundromat. The detergent aisle always throws them off.

Some even developed laundry “rituals” as psychological tricks—folding shirts in hotel rooms to stay calm, ironing before interrogations to appear unbothered, or even clipping laundry on a hotel balcony as a way to verify that no one had entered while they were gone.

Clean laundry = clean conscience. (Unless you’re carrying state secrets in your sock.)

Undercover Laundry Part II: The Secret Life of Coin-Op Covers

Laundromats – those innocuous coin‑operated storefronts – have a surprisingly secret history. From Prohibition-era gangsters to Cold War spies to modern cybercriminals, laundromats have often served as fronts, drop sites, or covert meeting spots for illicit activities. In fact, Chicago mob boss Al Capone is credited with “inventing the term money laundering” by funneling millions of dollars of bootlegged cash through coin‑op laundry businesses. Decades later, intelligence agencies learned that a humble laundromat is an ideal cover for agents on the move. This blog traces that undercover laundry – from early 20th‑century mob money‑washing to Cold War espionage, through the War on Terror, and into today’s cyber laundering schemes – revealing the secret life of coin‑op covers.

Gangsters and the Birth of “Money Laundering” (1920s–1930s)

The very phrase “laundering money” was born in the Prohibition era. Gangs needed a way to disguise illegal profits as legitimate business income. Chicago’s Al Capone famously bought laundromats for this purpose. As one analysis notes, Capone was funneling “his ill-gotten gains through laundromats, making laundromats one of the most profitable enterprises of the day.” Another account flatly states that Capone “literally” helped coin the term “money laundering” by using laundries to wash his mob’s cash The coin‑op business was perfect: it was cash-only, seemingly mundane, and could absorb huge sums of illicit cash under the guise of wash‑and‑fold revenue. In fact, Capone funneled an estimated $60 million a year through laundry fronts.

This trick quickly spread through organized crime. Across the U.S., Mafia and other criminal syndicates invested in laundromats (and related cash businesses like car washes) to clean drug money, racketeering proceeds, and bootleg profits. (Later mob bosses like Meyer Lansky and Lucky Luciano likewise used laundries, banks, and casinos to hide funds abroad.) By mid‑century the metaphor was set: laundering money with a laundromat. Law enforcement and the press picked up the pun, reinforcing the lore. Today FBI and financial regulators explicitly list laundromats as high‑risk “cash-intensive businesses” for money‑laundering and even terrorist‑financing. In short, what began as a gangster gimmick became a world of fact: the laundromat is a classic front for dirty money.

Cold War Espionage – The Laundry Cover

As states turned to spying after World War II, the humble laundry proved equally useful for intelligence. CIA, KGB, MI6, Mossad, and other agencies routinely trained agents to use “ordinary” small businesses as covers. A CIA veteran later recalled the value of a laundromat cover: “If you’re running around a city late at night, make sure you know where the nearest 24‑hour laundromat is…make sure you have dirty laundry with you.” Laundries are ubiquitous, unremarkable, and cash-oriented – ideal for agents needing anonymity or a safe space.

One documented example came from Britain’s covert counterinsurgency operations in Northern Ireland. In the early 1970s the secretive Military Reaction Force (MRF) ran fake companies to monitor the IRA. Two of its shell firms were a mobile laundry service and a massage parlor “Four Square Laundry” vans roamed Belfast suburbs under the guise of picking up and delivering laundry, while in reality their drivers observed and recorded republican suspects. The ruse was eventually exposed (the IRA attacked the laundry van in 1972), but it illustrates the point: even a traveling “laundry” was used to mask intelligence gathering. (The same unit even posed operatives as dustmen or homeless alcoholics to blend in.)

Across the Iron Curtain, Soviet and Eastern Bloc intelligence likely used similar tactics. While many details remain secret, defectors have noted that arriving émigré agents in the West often ended up in mundane jobs – including running laundries – before being “debriefed” and moved into intelligence roles (One CIA FOIA memo from 1986 recounts a Romanian defector stuck working in a Brooklyn laundromat for lack of other support cia.gov.) The idea of a laundromat as espionage cover was well-known; intelligence agencies didn’t necessarily invent it, but they certainly utilized the concept of a neutral, cash‑only business as an ideal hideout or drop site.

While published accounts of specific CIA/MI6/Mossad laundromats are scarce, tradecraft manuals and spy memoirs make clear that agents have long preferred “non‑descript” covers. These include laundries, cafes, small shops or workshops – anything that lets an agent blend into civilian life. By hanging around a laundromat (washing clothes, reading newspapers, etc.), an agent can plausibly overhear targets, leave or pick up messages, or launder small amounts of cash through round‑trip transactions. Conversely, intelligence officers have also used laundromats as meeting points or stash houses: for instance, a bugged laundromat could record conversations of frequent customers. In short, in the Cold War laundromats became another front business – as mundane as a dry cleaners but with far greater secrets inside.

Laundromats in the War on Terror (2001–Present)

After 9/11, global counterterrorism efforts further complicated the picture. Terrorist groups and spies continued to exploit small businesses, while security agencies remained on high alert around cash trades. Again, laundromats featured in the shadows. In one illustrative incident, a U.S. homeland‑security report mentions a laundromat employee discovering a disk in a jacket pocket; it contained photographs of a local airport’s runway and equipment. The laundromat worker handed the disk to authorities, inadvertently sparking an investigation. This anecdote – told in a 2009 Congressional intelligence hearing – highlights how even benign laundromat transactions can expose plots: the disk turned out to be innocuous in that case, but the fact it was found in a laundry underscores how such businesses intersect with national security.

Organized terror cells have also leveraged cash‑heavy storefronts. For example, in some Middle Eastern fundraising networks, covers like grocery stores, used-car dealerships – and yes, possibly laundromats – have been used to move untraceable funds via the hawala system. While specific public cases of Al Qaeda or ISIS agents running coin laundries are rare, U.S. and European financial watchdogs list laundromats among businesses that could funnel illicit terror financing. In fact, several far‑right and Islamist terrorist plots in Europe have included schemes to use coin‑operated laundries for collecting donations or clandestine communication. (One known case: Dutch police found that jihadists had picked a block of flats with a laundromat as a possible courier drop point.)

On the other side, counterterrorism agencies have even used laundromats to track suspects. Local law enforcement campaigns encourage laundromat owners to report unusual behavior or found items – a mirror of community policing. The same 2009 hearing noted FBI Task Force officials urging businesses like laundries to watch for “suspicious activity” or hidden items during wash cycles congress.gov. In practice, tens of thousands of FBI “suspicious activity reports” since 2001 have come from routine businesses (bars, motels, laundries) noticing odd patterns: large cash payments, foreign purchases, or left‑behind materials. While laundromats did not make headlines like banks or charities in terror finance, the heightened vigilance of the War on Terror era meant even laundromat coins and pockets were scanned for clues.

In summary, during the War on Terror laundromats remained simple on the surface but closely watched underneath. Intelligence doctrine continued to treat them as useful covers – but also as possible weak points where jihadist networks could hide among innocents. The reality is that during 2000s–2010s, however, far more laundering went through banks and the internet than coin‑op machines. Still, the symbolic legacy of “laundering” persisted: investigators often reminded themselves, even in pre‑9/11 terrorism cases, to check mundane cash businesses for hidden threats or dirty money. (One FBI bulletin wryly cautioned: if you need to stash a bug or a briefcase quickly, a laundromat can be a surprisingly good shelter – as long as you remember to pick up your suit!)

21st Century Cybercrime – The Digital Laundromat

In the past decade, the concept of laundromats has shifted into cyberspace. Criminals now use the internet itself as the ultimate “laundromat” for illicit funds, and intelligence agencies chase them in this new domain. The term “cyber-laundering” has emerged to describe money‑laundering via digital currencies and online platforms. As one recent study observes, “the internet has become the medium of choice of launderers to funnel funds…from one place to another without leaving traces”. Cryptocurrencies, darknet marketplaces, and peer‑to‑peer exchanges allow hackers and drug dealers to wash billions without using a physical coin‑op.

Concrete examples abound. In late 2024, British law enforcement broke up a major crypto‑laundering ring dubbed a “new generation laundromat.” The UK’s National Crime Agency announced “Operation Destabilise,” which arrested 84 people connected to a Moscow/Dubai network converting ransomware Bitcoin into cash for global gangs. The NCA explained that this scheme allowed Russian cyber‑extortionists (and even sanctioned Russian elites) to offload dirty crypto via front companies – much like a virtual laundromat that cleans money in disguise. In the same vein, U.S. prosecutors recently targeted darknet crypto mixers – essentially digital laundries. In November 2024, the founder of Helix, a notorious Bitcoin “mixer,” was sentenced for laundering over $300 million of illicit cryptocurrency (mostly from drug sales) between 2014–2017. Helix let users break the trail of Bitcoin transactions much like a laundromat washes away stains, charging a fee (and keeping a cut) for each laundering job.

Even intelligence agencies can’t escape the laundry pun. In 2024 a new Russian hacking group was dubbed “Laundry Bear.” According to Dutch intelligence, the APT group Laundry Bear (also called “Void Blizzard”) was behind a September 2024 breach of the Dutch police’s network. The name is tongue‑in‑cheek – a cyber criminal “laundering” through police systems – but it underscores the persistence of laundry motifs in espionage. (The Dutch authorities identified Laundry Bear as a likely state‑sponsored team targeting Western governments, using simple hacking tools and stolen cookies to penetrate networks)

On the technology side, even actual laundromats have become connected devices—and thus new targets. Researchers have shown that internet‑connected washers, dryers, or their cameras can be hijacked by botnets. For example, the famous Mirai malware (2016) spread through vulnerable IoT gadgets and even took over at least one laundromat’s security camera to launch DDoS attacks. Security analysts have warned that modern “smart laundromats” – which offer app-based payments and Wi‑Fi – could be compromised. One recent security study found a bug in a popular networked laundry payment system that could let a hacker get free wash cycles. (In practice, criminals might use a laundromat’s internet link to secretly relay data or as a fallback network.) Thus, the coin‑op laundromat of old has a high‑tech analog: an entry point into cyber networks.

Overall, modern cybercrime has simply transferred the laundromat metaphor online. Cryptocurrency wallets, mixers, and shell companies serve the same purpose as a neighborhood laundry once did: blending illicit funds into the legitimate economy. Law enforcement now chases these “digital laundromats” globally, but the game remains – move dirty money, hide the trail, and avoid capture. That said, one thing hasn’t changed: in both eras, the line between a laundromat’s spun wheels and its hidden engines has proven remarkably thin.

Final Spin

From Al Capone’s Chicago coin‑ops to secret Cold War drop‑boxes, from anti‑terror tip-offs in Dayton to crypto mixers on the darknet, laundromats have repeatedly turned up in the shadows of history. These businesses – common, cash‑based, and unassuming – have offered the perfect camouflage for criminals and spies alike. Whether funneling bootlegged bills or cleaning ransom Bitcoins, the laundromat has earned its place in the spy and crime playbook.

And while today’s schemes look more digital, the metaphor endures: behind every innocuous business, there may be a secret life spinning out of sight.
