Know the script.
Break the spell.
A scam rarely begins with a payment. It begins with a story designed to manufacture trust, fear, shame, urgency, isolation, or hope.
This guide records what each pattern is, the earliest reliable milestone we can support, who faces greater situational exposure, reported losses, major enforcement events, and the evidence signals Scamurai can test.
Method before mythology
Dates are documented milestones—not invented birthdays.
Many cons evolve over decades or centuries and have no provable creator. This library says “documented by,” “reported since,” or “publicly warned in” unless a reliable primary source establishes an origin.
Reported loss is not audited prevalence. Complaint totals may omit unreported harm, include duplicates, or use different definitions. Figures below identify the reporting system, year, and scope.
2025 reporting snapshot
One year.
Several views of harm.
FTC, FBI IC3, FinCEN, and NCMEC collect different kinds of reports. Their totals overlap and must not be added together.
Three million consumer fraud reports; $7.9B was investment fraud.
FTC testimony, March 2026 ↗201,266 complaints; 12,444 people reported losing over $100,000.
FBI 2025 IC3 Report, pp. 43–47 ↗More than 80,000 concerned sextortion; reports are not confirmed unique victims. NCMEC says expanded provider reporting duties under the 2024 REPORT Act affected the total.
NCMEC 2025 CyberTipline data ↗Core case files
The costume changes.
The pressure repeats.
Scamurai’s detector should look for combinations of verifiable behavior. It should never treat a platform, country, language, age, disability, or relationship as proof of harm.
Messaging · Smishing
Scam texts and “wrong number” openings
What it is
A believable alert, offer, delivery problem, toll notice, bank warning, job lead, or accidental message is used to trigger a reply, click, call, credential entry, or payment. “Smishing” is phishing delivered by SMS.
Documented milestone
Security agencies treat smishing as a channel variant of phishing, not a con invented by one culture. In 2024, consumers reported $470 million lost to scams that began by text—more than five times the 2020 figure.
Detection signals
- Unexpected package, toll, purchase, bank, job, or “wrong number” message
- Link domain does not match the named organization
- One-time code, password, card, or identity request
- Small fee or account-closure threat under a deadline
- Friendly mistake that pivots to romance, work, or investing
Who faces exposure
Anyone with a phone. Context raises risk: expecting a delivery, actively job hunting, traveling, or responding in a second language. The condition—not the person—is the target.
Relationships · Investment
WhatsApp romance and relationship-investment fraud
What it is
A criminal builds affection, friendship, or exclusivity, then invents a crisis or steers the relationship toward a fake crypto, gold, forex, or private investment platform.
History, scale, and enforcement
Online romance fraud predates WhatsApp. The FBI recorded nearly 15,000 confidence/romance complaints and over $230 million lost in 2016. IC3 recorded 23,159 complaints and $929.3 million lost in 2025 across all channels. In June 2024, two women were arrested in an alleged scheme involving at least 16 alleged victims and more than $7 million; charges remain allegations until proved.
Detection signals
- Rapid affection, exclusivity, or a shared-future script
- Fast move from a social or dating platform to WhatsApp
- Repeated inability to meet or verify live
- Military, travel, medical, visa, or frozen-account crisis
- Private investment group, fake profits, then withdrawal “taxes”
Who faces exposure
People seeking connection, grieving, isolated, newly divorced, traveling, or exploring investments may receive tailored approaches. Nearly 60% of people reporting a romance-scam loss to the FTC in 2025 said it began on social media.
Identity · Social media
Facebook catfishing and borrowed identities
What it is
Catfishing means presenting a fabricated or stolen identity online. It can lead to romance fraud, investment loss, sexual exploitation, stalking, or emotional harm—but not every fake profile requests money.
Documented milestone
The FBI was publicly using and defining “catfishing” by December 2013. That is an early authoritative record, not proof that impersonation began then. FTC data show $2.1 billion lost to all social-media-originated scams in 2025; that total is not catfishing loss.
Detection signals
- New account with sparse authentic history
- Photos or biography inconsistent across sources
- Immediate intensity and off-platform pressure
- Refusal of spontaneous voice, video, or independent verification
- Repeated failed meetings followed by money, image, or access requests
Evidence test
Check account age and history, perform a reverse-image search outside the conversation, ask for a spontaneous non-sensitive verification, and call known contacts through a saved number.
Child safety · Online enticement
Grooming, sextortion, and coercive online networks
What it is
An offender uses shared interests, flattery, gifts, secrecy, sexual conversation, threats, or escalating tasks to exploit a child or teen. It can begin in games, social media, messaging apps, or community servers.
History and major event
NCMEC’s CyberTipline has accepted child-exploitation reports since 1998; Discord is a delivery environment, not the origin of grooming. In April 2025, alleged leaders of the “764” network were charged over conduct said to span late 2020 through early 2025. Charges remain allegations unless proved.
Detection signals
- Older user pretends to be the child’s age
- Praise, game currency, food, gifts, or favors build obligation
- Move to a private room, encrypted app, or adult space
- Requests for images, private video, secrecy, or an offline meeting
- Threats of exposure, self-harm tasks, doxxing, or swatting
Who faces exposure
NCMEC reports that teenage boys are frequently targeted in financially motivated sextortion. The FBI says violent online networks deliberately seek children experiencing depression, eating disorders, or suicidal ideation. That is offender targeting—not fault in the child.
Family · Caregiving · Elder justice
Older-adult exploitation and grandchild emergencies
What it is
Strangers may impersonate relatives, banks, police, lawyers, tech support, or romantic partners. Financial exploitation may also come from a trusted caregiver, friend, fiduciary, or relative.
History and major case
The FBI says IC3 had received grandparent-scam reports since 2008. In March 2025, prosecutors charged 25 Canadian nationals in an alleged call-center conspiracy said to have taken over $21 million from older Americans in more than 40 states.
Detection signals
- Relative claims arrest, crash, injury, kidnapping, or travel crisis
- Call passes to a supposed lawyer, doctor, police officer, or bondsman
- “Gag order” or instruction not to tell family or the bank
- Cash courier, wire, crypto, or gift-card demand
- New signer, beneficiary, unexplained withdrawal, or caregiver control
Scale without exaggeration
FinCEN analyzed $27 billion in suspicious elder-exploitation activity in filings from June 2022–June 2023. That is not a loss total: it can include attempts, duplicates, transfers, and amendments. About 80% of analyzed filings involved stranger/imposter scams and 20% theft by someone trusted.
Banking · Account takeover
Fake fraud departments and “safe account” transfers
What it is
A supposed bank security team reports suspicious activity, then asks for a one-time code, remote access, or a transfer to “protect” the money. A real bank does not need a customer to move funds into a stranger-controlled safe account.
Reported scale
The FTC said people reported nearly $1 billion lost to business impersonators in 2025, with bank impersonators producing the highest losses in that group. IC3 separately approximated 4,700 account-takeover complaints and $359.7 million in loss.
Detection signals
- Password reset, MFA change, SIM port, or new recovery method
- Unknown-device login or sudden account lockout
- Fraud alert followed by a one-time-code request
- New payee and rapid wire, ACH, P2P, or crypto transfer
- Instruction to ignore the number on the bank card
Safe response
End the contact. Call the number printed on the bank card or use the institution’s known app. Ask the fraud team to verify recent security changes and transfers. Report active theft quickly; recovery options narrow with time.
Extortion · Reputation
Sextortion, deepfake threats, and professional blackmail
What it is
Real, stolen, altered, or fabricated intimate material is used to demand money, more content, access, silence, or another act. A teacher, executive, official, or public figure may face threats aimed at students, parents, boards, voters, coworkers, or media.
Reported scale
IC3 received more than 75,000 sextortion submissions in 2025 and referred over 5,700 involving children to NCMEC. The age rows total about $44.2 million in adjusted loss, but financial loss does not capture safety or psychological harm.
Detection signals
- Fast request for intimate media or private video
- Immediate screenshot of followers, school, employer, or family
- Collage or deepfake paired with an exposure threat
- Gift-card, P2P, wire, or crypto demand
- Repeated demand after payment or compliance
Who faces exposure
IC3’s largest 2025 complaint count was ages 20–29; under-20 complainants numbered 11,316. Current authoritative data do not establish that teachers or people in power are the most frequently targeted group—only that public-facing roles can increase threatened reputational harm.
Work · Authority · Payments
Business-email compromise and executive impersonation
What it is
A criminal impersonates or compromises an executive, vendor, school administrator, payroll contact, title company, board member, or trusted professional to redirect a payment or sensitive record.
Reported scale
IC3 recorded 24,768 business-email-compromise complaints and $3.047 billion in reported loss in 2025, the second-highest cyber-enabled fraud loss category after investment fraud.
Detection signals
- New payment instructions or bank-account change
- Look-alike domain or altered reply-to address
- Executive urgency paired with secrecy
- Payroll, W-2, student, donor, or vendor-data request
- Request bypasses an established approval path
Evidence test
Verify any payment or credential change through a known phone number and a second authorized person. Compare the full domain, reply-to address, prior invoice details, and known vendor process.
Immigration · Language · Authority
Notario, embassy, immigration, and legal-service fraud
What it is
A supposed notario, consultant, travel agent, official, or insider guarantees a visa, work permit, green card, asylum result, tax resolution, or special access—then requests money, original documents, or false forms.
Documented milestone
The U.S. meaning of “notary public” differs sharply from the legal authority associated with notario in parts of Latin America. That semantic mismatch is the mechanism; culture is not the risk. DOJ issued a national notario warning in July 2009.
Detection signals
- Guaranteed legal or immigration outcome
- Payment for free government forms
- Blank, false, or untranslated document
- Threat of arrest or deportation unless paid immediately
- Gift card, crypto, wire, or P2P demand from an “official”
Major case
In June 2024, a consultant was sentenced to 63 months after a scheme targeting Spanish- and Haitian Creole-speaking communities involved more than 1,000 victims and over $3.9 million. No authoritative nationwide total specific to immigrants or non-English speakers was located in the primary sources reviewed for this guide.
How scammers adapt to context
Global scripts.
Local costume.
These labels describe documented criminal scripts and enforcement ecosystems—not a nation, culture, language, faith, or diaspora. Scamurai tests the threat, secrecy, identity claim, and transfer pattern.
Chinese police, embassy, or consulate script
A delivery company, bank, embassy, or consulate transfers a Chinese-speaking target to fake police. False warrants, nonstop video “monitoring,” secrecy, and bail or proof-of-innocence payments follow.
Detect:Foreign-authority claim, surveillance demand, secrecy, and payment—not Chinese language or nationality.
FBI warning, May 9, 2024 ↗Blessing or curse valuables-switch scam
Strangers claim illness, a curse, or misfortune threatens a family, request cash or jewelry for a ritual, switch the bag, then delay inspection. The premise deserves respect; the fraud is the threat, valuables request, secrecy, and switch.
Documented impact:SFPD reported about $374,000 in cash/property losses from late 2025 through January 2026.
SFPD safety guidance ↗Romance baiting from transnational scam centers
Criminal organizations build a friendship or romance before steering a target into a fake investment. INTERPOL’s 2024 assessment dates this scam-center romance-baiting variant to Asia in 2019 and says it expanded during the COVID-19 pandemic; some people forced to work in scam centers are themselves trafficking victims.
Reported impact and major action:IC3 recorded $7.228 billion in cryptocurrency-investment loss in 2025. Not every case was relationship-enabled. On April 23, 2026, DOJ announced charges against two alleged scam-center managers, seizure of 503 fake investment domains, and restraint of about $702 million in cryptocurrency.
INTERPOL 2024 assessment ↗FBI 2025 IC3 crypto trends ↗DOJ action, April 23, 2026 ↗“419,” inheritance, and Spanish lottery variants
The historical “419” label refers to a Nigerian criminal-code provision, not Nigerian people. The FBI says the scheme has been around since the early 1980s. The script promises a prize, inheritance, contract, loan, or transfer—but taxes and certificates must be paid first.
Reported impact and major case:IC3 recorded 7,762 advance-fee complaints and $155.9 million lost in 2025. An FBI 2005 Spanish-lottery warning estimated that one variant sent six million letters and took an estimated $24 million a year. In June 2024, a participant was sentenced in a Nigeria-orchestrated advance-fee scheme involving more than $5.6 million worldwide.
FBI: “419” history ↗FBI Spanish-lottery archive ↗DOJ sentence, June 2024 ↗Jamaica-linked lottery call-center fraud
An unsolicited prize requires taxes or fees before release. Requests escalate, trusted institutions are impersonated, and some targets are recruited to receive or resend other victims’ money. This is a documented transnational criminal ecosystem—not a trait of Jamaican culture.
Major event:A May 2026 sentence involved a broker who sold seven million older Americans’ records to lottery scammers; documented victim losses exceeded $9.5 million.
DOJ sentence, May 28, 2026 ↗One-ring or “Wangiri” fraud
A robocaller rings once—often at night—to provoke a callback to an international premium-rate number. The useful signals are repeated short calls, an unfamiliar country code, and callback charges, not the apparent country itself.
Documented milestone:The U.S. Federal Communications Commission issued a national one-ring alert on May 3, 2019.
FCC one-ring alert ↗Who is more susceptible?
Exposure is contextual.
It is not destiny.
Useful protection identifies the leverage a criminal selected. It does not label a group as gullible, unstable, or unsafe.
| Exploited circumstance | Common script | Protective countermeasure |
|---|---|---|
| Love, grief, loneliness, or a new relationship | Romance, catfishing, investment pivot | Independent identity check; never let an online-only contact direct investments |
| Fear for a child, grandchild, or reputation | Emergency impersonation, sextortion, blackmail | Family safe phrase; known-number callback; preserve and report instead of paying |
| Unfamiliar language, law, bank, or immigration system | Notario, embassy, tax, or bank authority | Qualified interpreter; independently located official contact; licensed or accredited adviser |
| Cognitive overload, communication or access barriers, distress, or isolation | Repeated calls, coercion, caregiver control, escalating tasks | Trusted human review; shorter decisions; visible consent; no identity-based risk score |
| Public role or access to funds and records | BEC, payroll diversion, deepfake or reputation threat | Two-person verification; known-channel callback; separate payment and identity approval |
| Adolescence, online belonging, gaming, or secrecy | Grooming, gifts, sextortion, violent online network | Non-blaming conversation; transparent family safeguards; rapid trusted-adult escalation |
U.S. report and recovery routes
Speed matters.
Shame helps the offender.
Reporting does not guarantee recovery, but it can preserve options, connect related cases, and protect another person. For active theft, contact the bank or payment provider immediately. For imminent danger, call local emergency services or 911; in the U.S., call or text 988 for suicide or mental-health crisis support.
