GrayCat PI | International Fraud Awareness Week 2026 | November 15–21, 2026

GrayCat PI is an Official Supporter of International Fraud Awareness Week 2026 and appears in the ACFE’s official 2026 Supporting Organizations directory.

Fraud is a risk. Verification is a decision.

Fraud can begin with an inconsistent document, an unexplained payment, an unverified business partner or a story that does not match the available evidence. During Fraud Week 2026, GrayCat PI shares practical guidance for organizations and individuals dealing with fraud risks involving Mexico.

  • For organizations: Strengthen verification, reporting and response.
  • For individuals: Understand what to preserve, verify and do next.

Fraud is not always obvious

Occupational fraud can involve asset misappropriation, corruption and financial statement fraud within an organization. Consumer-facing fraud can take other forms, including investment, property, identity and relationship scams. The risks and evidence requirements differ.

A warning sign is a reason to verify. It is not proof that fraud occurred.

What ACFE’s 2026 research says

ACFE’s Occupational Fraud 2026: A Report to the Nations is the 14th edition of its global study of occupational fraud. It is based on the ACFE 2025 Global Fraud Survey, which received 10,276 responses. The report uses 2,402 usable case narratives describing completed occupational-fraud investigations by Certified Fraud Examiners (CFEs).

The cases came from 143 countries and territories and 22 industry categories. Together, they involved more than US$3.4 billion in losses. The median loss was US$104,000 per case, and the average was US$1,457,000.

Other findings include:

  • Tips were the most common detection method, accounting for 43% of cases. More than half of those tips came from employees.
  • The median fraud scheme lasted 12 months before detection.
  • 84% of perpetrators in the cases displayed at least one behavioral red flag before detection.
  • Organizations that trained both employees and management reported median losses of US$84,000 per case, compared with US$150,000 where neither group received fraud-awareness training.

How to interpret these figures: The survey asked CFE respondents to describe the single largest occupational-fraud case they had investigated that met the report’s criteria. These are global occupational-fraud findings. They are not a census of all fraud, do not measure consumer scams and should not be interpreted as Mexico-specific prevalence.

Technology is changing fraud risk

The 2026 ACFE/SAS Anti-Fraud Technology Benchmarking Report surveyed 713 fraud fighters across eight regions.

  • 25% of surveyed organizations currently use AI or machine learning in anti-fraud data analysis.
  • Another 28% expect to adopt these tools within the next two years.
  • Only 7% of respondents said their organizations were more than moderately prepared to detect or prevent AI-powered fraud.
  • 55% of respondents expect deepfake social engineering and generative-AI document fraud or forgery to increase significantly over the next 24 months.

These findings describe the organizations and professionals surveyed. The expectations are not a measurement of actual fraud incidence in Mexico. They support stronger identity, source and instruction verification, along with governance and human review. They do not mean every unusual message or document was generated by AI.

For organizations: verify before you pay

Fraud exposure can arise in procurement, payroll, expense claims, insurance, property transactions, vendor relationships and payment processes.

Practical checks include:

  1. Verify new vendors and changes in ownership or control using independent sources.
  2. Confirm bank-account or payment-instruction changes through a previously known contact method. Do not reply to the message requesting the change or rely only on the contact details it supplies.
  3. Separate the person requesting a payment change from the person approving it.
  4. Review unusual transactions, repeated exceptions, duplicate invoices and unexplained overrides.
  5. Make reporting channels visible and explain how reports are handled.
  6. Train employees and managers to recognize and report concerns.
  7. Preserve relevant records and establish a clear escalation process.

A checklist can help identify control gaps. It is not a formal audit, fraud examination or guarantee that fraud will be prevented.

For individuals: pause, preserve and verify

If you suspect an investment, property, identity or relationship scam involving Mexico:

  1. Pause before sending more money or documents.
  2. If a transfer or payment has occurred, contact your bank or payment provider promptly. Ask what options may be available.
  3. Preserve original messages, emails, URLs, account names, phone numbers, receipts and transaction references.
  4. Create a dated timeline of contact, promises, payments and events.
  5. Verify the person, company, property or investment independently. Do not rely only on contact details supplied by the person asking for money.
  6. Avoid confronting or alerting a suspected subject if doing so could create a safety risk or compromise evidence.
  7. Consider appropriate legal advice and reporting to the relevant authorities.
  8. Be cautious of recovery offers that demand advance fees or promise guaranteed results.

Do not send identity documents, banking credentials or sensitive case evidence through public social-media comments or messages.

Red flag or proof?

An inconsistency, unusual payment, unexplained relationship with a vendor, refusal to provide information or suspicious document may justify further review. None of these facts, by itself, establishes that a person committed fraud.

A sound assessment separates:

  • what is directly documented;
  • what can be independently corroborated;
  • what remains an allegation, hypothesis or explanation;
  • what is unknown or outside the available records.

The objective is to test the facts fairly, consider alternative explanations and document limitations.
