  4. Did they ask for a password, PIN, or one-time code?
  5. Did they ask you to keep it secret?
  6. Do they say they are from your bank, the government, or tech support?

📖 Full guide with every step and source

What to do now

If something happened to you, an attack, a fraud, or a scam, take a breath. You are not alone, and it is not your fault. Scammers are professionals who work hard to fool kind, careful people. This page walks you through calm, numbered steps, one at a time. You don't have to do everything today.

For people in the United States, with extra Texas resources. Every link and phone number on this page was checked on the official site on 2026-10-26. This page is information, not legal advice.

Steps by time

Right now

  1. If you are in danger, call 911.
  2. Stop all contact with the scammer. Hang up. Don't reply.
  3. If a computer may be infected, disconnect it from the internet: unplug the network cable or turn off its Wi-Fi. If you cannot disconnect it, CISA's checklist says to power the device down to stop the spread, and notes this loses some evidence, so do it only if you can't disconnect another way. (CISA – I've been hit by ransomware!)
  4. If money or card details were involved, call your bank or card company using the number on the back of your card. Ask them to stop or reverse the payment.
  5. Take screenshots of everything before deleting anything.

Today

  1. Report it: ReportFraud.ftc.gov (Federal Trade Commission) and FBI Internet Crime Complaint Center (IC3).
  2. Report it to your local police. Ask for the report number and keep it. (The FCC also advises filing a police report after a SIM swap. FCC – Cell phone fraud (SIM swapping and port-out scams))
  3. From a device you trust, change passwords on important accounts (email first, then bank) and turn on two-step verification. (CISA – Turn on MFA)
  4. If your Social Security number or identity was used, go to IdentityTheft.gov (FTC) for a recovery plan.

This week

  1. Freeze your credit at all three bureaus. It's free, and each one must be done separately: Equifax – Security freeze (888) 298-0045, Experian – Credit freeze 1-888-397-3742, TransUnion – Credit freeze 800-916-8800.
  2. Get your free credit reports at AnnualCreditReport.com and look for anything you don't recognize.
  3. If a bank, card, money transfer or crypto company won't help, you can file a complaint with the Consumer Financial Protection Bureau – Submit a complaint (855) 411-2372.
  4. Texans: you can also file a complaint with the Texas Attorney General – File a consumer complaint.

Ongoing

  1. Watch your bank and card statements for anything unfamiliar.
  2. Be very careful of anyone who offers to "recover" your money for a fee. That is a second scam; see the pig butchering section.
  3. Be gentle with yourself. If you feel overwhelmed, call or text 988.

Money sent, or bank or card fraud

  1. Call your bank or card issuer right away, using the number on the back of your card or in your bank's app. Tell them it was fraud and ask them to reverse the payment.
  2. Bank impersonation texts often look like a security alert asking you to confirm a large purchase. If you reply, a fake "fraud department" may call you. The FDIC says to call your bank directly using a number you know. (FDIC – Bank impersonation scams and fake banks (June 2025))
  3. If a text asks you to reply with a code you're about to receive, a scammer is probably trying to log into your account right now. Stop replying. (OCC HelpWithMyBank – Multifactor authentication and scams)
  4. Report it at ReportFraud.ftc.gov (Federal Trade Commission). If the bank doesn't resolve it, complain to the Consumer Financial Protection Bureau – Submit a complaint.
  5. Not sure a bank website is real? You can call the FDIC at 1-877-275-3342 (1-877-ASK-FDIC).

Identity theft

  1. Go to IdentityTheft.gov (FTC). Report what happened and follow your personal recovery plan.
  2. If your information was exposed but not yet misused, follow IdentityTheft.gov – data breach steps.
  3. Freeze your credit at Equifax, Experian and TransUnion (links above).
  4. Texans: the Texas Attorney General – Consumer Protection has identity theft help.

Account hacked or password stolen

  1. Use a device you trust. Change the password on the account, and anywhere else you used the same password.
  2. Sign out of all other sessions or devices in the account's security settings.
  3. Turn on multifactor authentication. CISA: go to Settings, then Security, look for two-factor or two-step, and turn it on. (CISA – Turn on MFA)
  4. Never give a verification code to anyone. Only you should use it to log in. (OCC HelpWithMyBank – Multifactor authentication and scams)
  5. Tell your friends and family your account was hacked, so they ignore any requests for money that came "from you".

Phone or SIM taken over

In a SIM swap or port-out scam, a scammer gets your phone number moved to their device, then uses your texts to reset your passwords. (FCC – Cell phone fraud (SIM swapping and port-out scams))

Warning sign: your phone suddenly has no service when it normally would.

  1. Contact your phone company from another phone.
  2. Contact your bank and other financial institutions.
  3. File a police report.
  4. Afterwards, ask your phone company to add a PIN or password to your account. (NSFR advice.)

Steps from the FCC's SIM swapping guidance. FCC – Cell phone fraud (SIM swapping and port-out scams)

Device-pairing and code-sharing scams, and "turn it off"

This is one of the most important sections on this page. These scams don't need to "break" your phone. They trick you into letting them in, by scanning a QR code, typing in a code, or approving a pairing or sign-in.

How it works, step by step

  1. Linked-device QR codes. Apps like Signal and WhatsApp let you use your account on more than one device by scanning a QR code. Google found attackers disguising "link a new device" QR codes as group invites, security alerts, or pairing instructions. If you scan one, your messages can be delivered to the attacker in real time. (Google Threat Intelligence – Russia-aligned actors targeting Signal “linked devices” (Feb. 2025))
  2. Device-code phishing. Microsoft reported a campaign where people got a fake meeting invitation and were asked to type a code into a real sign-in page. The code had been created by the attacker, so typing it in gave the attacker access to the account. (Microsoft Threat Intelligence – Storm-2372 device code phishing (Feb. 13, 2025))
  3. Code and approval requests. Someone asks you to read back a code that was just sent to you, or to tap "approve" on a sign-in you didn't start. A bank representative will never call you and ask for your authentication code. (OCC HelpWithMyBank – Multifactor authentication and scams)

Red flags

  • Anyone asking for a code that was sent to you.
  • A QR code that is supposed to be a group invite, an alert, or "security" instructions.
  • A sign-in or pairing request you did not start.

What to do now

  1. Never share a code, and never approve a pairing, sign-in, or code you didn't start.
  2. Open the app's settings, look at its linked devices list, and remove any device you don't recognize.
  3. Change your password from a trusted device and turn on multifactor authentication. (CISA – Turn on MFA)

Turn it off

  1. Turn off Bluetooth when you're not using it.
  2. Don't leave your device in Bluetooth discovery ("discoverable") mode when you don't need it.
  3. Don't accept pairing attempts you didn't start.
  4. Check now and then which devices are connected or paired, and remove any you don't know.
  5. Turn off Wi-Fi auto-connect (auto-join).
  6. When you're done with a public Wi-Fi network, log out of it and "Forget" it. Delete Wi-Fi networks you no longer use.

The "Turn it off" steps come from NSA's guidance on securing wireless devices in public. NSA – Securing Wireless Devices in Public Settings (July 2021, PDF; public copy hosted by InfraGard LA) (announced by CISA: CISA – NSA releases guidance on securing wireless devices while in public)

Ransomware and computer attacks (the "README" ransom note)

What is a "README" ransom note? Ransomware locks or scrambles your files, then leaves a message, often a text file with a name like README, saying who did it and how to pay. In the 2023 Dallas attack, the city's report includes the content of the attackers' "README.txt" message. (City of Dallas – After-Action Report, May 2023 ransomware incident (PDF))

If you see a ransom note

  1. Don't open any links in it, and don't contact the attackers.
  2. Take a photo or screenshot of the note.
  3. Disconnect the device from the internet: unplug the network cable or remove it from Wi-Fi. If you cannot disconnect it, power it down. CISA notes that powering down loses some evidence, so only do it if you can't disconnect another way. (CISA – I've been hit by ransomware!)
  4. Don't pay, and don't negotiate.
  5. Report it to the police, to FBI Internet Crime Complaint Center (IC3), and to CISA at CISA – Report an incident 1-844-729-2472. IC3 asks for the ransomware name if known, the file extension of encrypted files, the crypto address, the attackers' email and websites, and the ransom amount. (IC3 – Ransomware)
  6. Restore from a clean, offline backup only after the device has been cleaned.

The "FBI is calling" / safe-account scam

The FBI calls one version of this the "Phantom Hacker" scam. It layers a fake tech-support agent, a fake bank, and a fake government agent to build your trust, and it has cost people their life savings. (FBI IC3 PSA – “Phantom Hacker” scams target senior citizens (Sept. 29, 2023))

How it works, step by step

  1. A scary call, text, email or computer pop-up says your computer or accounts have been hacked. The caller ID or message may look real.
  2. You are passed to a fake "fraud department" at your bank, then to a fake government agent (for example, someone claiming to be from the Federal Reserve or another agency). They may even send a letter on fake official letterhead. (FBI IC3 PSA – “Phantom Hacker” scams target senior citizens (Sept. 29, 2023))
  3. They tell you to keep it secret, and not to tell anyone the real reason you're moving money. (FBI IC3 PSA – “Phantom Hacker” scams target senior citizens (Sept. 29, 2023))
  4. They tell you to move your money to a "safe" account: by wire, cash, cryptocurrency (including at a crypto ATM), or by buying gold or silver. (FBI IC3 PSA – “Phantom Hacker” scams target senior citizens (Sept. 29, 2023), FBI IC3 PSA I-012924-PSA – Scammers use couriers to retrieve cash and precious metals (Jan. 29, 2024))
  5. A "courier" may come to your home or meet you somewhere to pick up the cash or gold, sometimes using a passcode like a dollar bill's serial number. (FBI IC3 PSA I-012924-PSA – Scammers use couriers to retrieve cash and precious metals (Jan. 29, 2024))
  6. They come back again and again, over days or months, until there is nothing left. (FBI IC3 PSA – “Phantom Hacker” scams target senior citizens (Sept. 29, 2023))

The truth

What to do now

  1. Hang up. Call your bank using the number on the back of your card.
  2. Never give your address to, or meet, anyone collecting cash or gold. (FBI IC3 PSA I-012924-PSA – Scammers use couriers to retrieve cash and precious metals (Jan. 29, 2024))
  3. Report it to FBI Internet Crime Complaint Center (IC3) and your local police. If you're 60 or older, the National Elder Fraud Hotline 833-372-8311 can help you file. (FBI IC3 PSA I-012924-PSA – Scammers use couriers to retrieve cash and precious metals (Jan. 29, 2024))

Verified figures: between January and June 2023, IC3 received 19,000 complaints about tech support scams, with estimated losses over $542 million; almost 50% of victims were over 60 and accounted for 66% of losses (FBI IC3 PSA – “Phantom Hacker” scams target senior citizens (Sept. 29, 2023)). From May to December 2023, IC3 saw aggregated losses over $55 million from courier pickups of cash and precious metals (FBI IC3 PSA I-012924-PSA – Scammers use couriers to retrieve cash and precious metals (Jan. 29, 2024)).

The "we have your IP address" scam

Some scammers send scary messages saying they "tracked your IP address", "hacked your network", or "recorded you", and demand money, often in Bitcoin, within a short deadline. These threats are meant to make you afraid and rush you. A government guide on these scams says such a message "does not in itself prove that your device or email account has been hacked", and the same message is usually sent to huge numbers of people. (Traficom (Finnish Transport and Communications Agency) – Sextortion scams: don't believe the scammers' claims) The FBI lists red flags: your old password quoted to scare you, claims of spyware or a recorded video, a short window to pay (typically 48 hours), and payment in Bitcoin. (FBI IC3 PSA – Online extortion scams (Apr. 20, 2020))

  1. If you shared any money or information, contact your bank right away, using the number on the back of your card.
  2. If you truly think a device or your home network is compromised, turn off your router and modem (unplug them) to cut the connection. Before you reconnect, get help to reset the router, change the Wi-Fi password and the router's admin password, and update its software (firmware). (NSFR safety advice; the "disconnect" step follows CISA's guidance: CISA – I've been hit by ransomware!)
  3. Do not ever pay. "The FBI does not condone the payment of online extortion demands." (FBI IC3 PSA – Online extortion scams (Apr. 20, 2020))
  4. Don't reply or negotiate. Take screenshots, then report it to FBI Internet Crime Complaint Center (IC3) and your local police. If the message quotes a password you still use, change it everywhere you use it. (Traficom (Finnish Transport and Communications Agency) – Sextortion scams: don't believe the scammers' claims)

Pig butchering (crypto investment scams)

"Pig butchering" is the name for scams where someone builds a friendship or romance with you, then leads you into a fake cryptocurrency investment. The U.S. Treasury's FinCEN described it in a 2023 alert. (FinCEN Alert FIN-2023-Alert005 on “pig butchering” (PDF))

How it works, step by step

  1. First contact. A text, social media message, dating site or professional networking message, often pretending to be a "wrong number" or an old friend. (FinCEN Alert FIN-2023-Alert005 on “pig butchering” (PDF))
  2. Trust. Days or weeks of friendly or romantic conversation. (FinCEN Alert FIN-2023-Alert005 on “pig butchering” (PDF), U.S. Department of Justice – Prince Group indictment and forfeiture (Oct. 14, 2025))
  3. The "investment". They show you a website or app with fake, extraordinary returns. (FinCEN Alert FIN-2023-Alert005 on “pig butchering” (PDF))
  4. A small withdrawal. They may let you take out a small amount, to make you trust it. (FinCEN Alert FIN-2023-Alert005 on “pig butchering” (PDF))
  5. Pressure to deposit more. Some victims have sold retirement savings or taken out home equity loans. (FinCEN Alert FIN-2023-Alert005 on “pig butchering” (PDF))
  6. "Taxes" or "fees" to withdraw. When you try to take your money out, they demand taxes or early withdrawal fees. (FinCEN Alert FIN-2023-Alert005 on “pig butchering” (PDF))
  7. Gone. When you can't or won't pay more, they disappear with everything. (FinCEN Alert FIN-2023-Alert005 on “pig butchering” (PDF))
  8. The second scam. Afterwards, people may contact you offering to recover your lost money for a fee. Never pay anyone who promises to get your money back. (NSFR safety advice.)

Red flags

  • A stranger who "texted the wrong number" and wants to keep chatting.
  • An online friend or love interest who talks about crypto profits.
  • An app or website showing huge, steady gains.
  • Any fee or tax you must pay before you can withdraw.

What to do now

  1. Stop sending money, including any "fees" or "taxes".
  2. Contact the crypto exchange or ATM operator and your bank; tell them it was fraud.
  3. Take screenshots of the chats, the website address, wallet addresses and transactions.
  4. Report it to FBI Internet Crime Complaint Center (IC3), ReportFraud.ftc.gov (Federal Trade Commission), and your local police.

Recent case: on Oct. 14, 2025, the Justice Department announced an indictment of the chairman of Cambodia-based Prince Group for directing forced-labor scam compounds that ran "pig butchering" scams, and filed a civil forfeiture complaint against approximately 127,271 bitcoin, then worth approximately $15 billion, described as the largest forfeiture action in DOJ history. An indictment is an allegation; the defendant is presumed innocent. (U.S. Department of Justice – Prince Group indictment and forfeiture (Oct. 14, 2025)) The IC3's 2024 report describes "pig butchering" as a confidence-based scam in which "victims are coached to invest more and more money … only to be unable to withdraw their funds." (FBI IC3 2024 Internet Crime Report (PDF))

Financial scams on social sites

These are financial scams that start with a friendly message, an ad, or a post. If one happened to you, please remember: it happened because someone set out to deceive you, not because you did something foolish.

Romance scams

How: a stranger builds a loving relationship online, then asks for money or an "investment". Red flags: they can never meet or video chat, and there's always an emergency. What to do: stop sending money, take screenshots, call your bank, and report to ReportFraud.ftc.gov (Federal Trade Commission) and FBI Internet Crime Complaint Center (IC3).

Funeral, obituary and grief scams

We are so sorry for your loss. Some scammers copy the details of someone who has died to make fake funeral pages. In a case reported by the Better Business Bureau in Jan. 2024, a fake Facebook account using a deceased person's identity said it had the "official live stream" of the funeral, and the link required a paid membership. A funeral director quoted in the report said a funeral home will not charge a fee just to watch a service. (WGEM News – BBB warns of fake funeral livestream pages (Jan. 2024)) What to do: ask the funeral home directly for the real link; don't enter card details; report the post to the social site, to BBB Scam Tracker, and to the funeral home. Be careful, too, of anyone who suddenly contacts a grieving family to collect a "debt" or settle an "estate": verify with the company or the court using contact details you find yourself.

Fake investment and crypto ("pig butchering")

See the pig butchering section.

Fake jobs and "tasks"

How: a job that pays you for simple online tasks, then asks you to deposit your own money to "unlock" earnings. What to do: stop paying; report to ReportFraud.ftc.gov (Federal Trade Commission) and FBI Internet Crime Complaint Center (IC3).

Government and tech-support impersonation

See the "FBI is calling" section.

Sextortion and threats

See the "we have your IP address" section. Don't pay, don't reply, take screenshots, and report. If you're a young person or a parent, please talk to someone you trust; you're not in trouble for asking for help.

Marketplace scams

How: items advertised on social media that never arrive. What to do: contact your card company or payment app, and report to ReportFraud.ftc.gov (Federal Trade Commission).

Grandparent and family emergency scams

How: a call or text saying a grandchild or relative is in trouble and needs money now, and to keep it secret. What to do: hang up, then call your relative or another family member on a number you already know.

Verified figures from the FBI's 2024 Internet Crime Report (FBI IC3 2024 Internet Crime Report (PDF)): reported losses of $16.6 billion in 2024; people over 60 filed 147,127 complaints with $4.8 billion in losses; investment fraud losses of $6,570,639,864; confidence/romance losses of $672,009,052; and 10,956 complaints with $246.7 million in losses involving cryptocurrency ATMs/kiosks.

Smishing and phishing

Smishing is phishing by text message: fake texts that trick you into clicking a link, sharing information, or sending money. (FBI IC3 PSA I-041224-PSA – Smishing scam regarding debt for road toll services (Apr. 12, 2024)) Phishing does the same by email.

What to do with any suspicious text or email

  1. Don't click the link and don't reply.
  2. Check using the company's official app, or a website or phone number you already know.
  3. Forward scam texts to 7726 (SPAM). (U.S. Postal Inspection Service – Smishing: package tracking text scams)
  4. Forward phishing emails to reportphishing@apwg.org. (Anti-Phishing Working Group – Report phishing emails)
  5. Report it at ReportFraud.ftc.gov (Federal Trade Commission) or FBI Internet Crime Complaint Center (IC3), then delete it.
  6. If you already clicked or entered information, call your bank and change your passwords.

Example messages below are illustrative only. They are not real messages; links and numbers are placeholders.

Package redelivery (USPS)

Example message (illustrative)

USPS: Your package could not be delivered. Update your address here: [link]

Red flag / what to know: USPS will not text you unless you asked for tracking with a tracking number, and its texts will NOT contain a link. Report USPS scams to spam@uspis.gov. (U.S. Postal Inspection Service – Smishing: package tracking text scams)

Amazon / Apple account

Example message (illustrative)

Your account is locked due to suspicious activity. Verify here: [link]

Red flag / what to know: Open the app or type the website yourself; never use the link. (CISA – Recognize and report phishing)

"Hi Mum / Hi Dad"

Example message (illustrative)

Hi Mum, I broke my phone, this is my new number. Can you help me pay a bill?

Red flag / what to know: Call your child on the number you already have. (ReportFraud.ftc.gov (Federal Trade Commission))

Fake invoice (email)

Example message (illustrative)

Red flag / what to know: Look up the company yourself; don't call the number in the email. (CISA – Recognize and report phishing)

Password reset (email)

Example message (illustrative)

We received a request to reset your password. If this wasn't you, sign in here: [link]

Red flag / what to know: Go to the site yourself, not through the link. (CISA – Recognize and report phishing)

Gift cards for the "boss" (email)

Example message (illustrative)

I'm in a meeting. Buy [number] gift cards and send me the codes. Keep this quiet.

Red flag / what to know: A real boss won't ask for gift card codes. Check by phone or in person. (ReportFraud.ftc.gov (Federal Trade Commission))

Understanding the attack: man-in-the-middle and session hijacking

Man-in-the-middle means someone secretly sits between your device and the website you're using, so they can see or change what you send. Session hijacking means they grab your signed-in session and use it to log in as you. On unsecured public Wi-Fi, other users "can see what you see and what you send. They could hijack your session and log in as you." (FTC – Wise Up about Wi-Fi (PDF, govinfo.gov))

Evil-twin hotspots and "stripped" secure connections

An attacker can set up a fake access point, an "evil twin", that mimics the nearby public Wi-Fi, giving them access to data sent over it. (NSA – Securing Wireless Devices in Public Settings (July 2021, PDF; public copy hosted by InfraGard LA)) A related trick tries to push your browser onto an unencrypted page.

Warning signs

  • No padlock or "https" in the address bar on a site that normally has one. If you think you're on an encrypted site but find yourself on an unencrypted page, log out right away. (FTC – Wise Up about Wi-Fi (PDF, govinfo.gov))
  • A browser security or certificate warning on a site you use every day.

What to do now

  1. Disconnect from the untrusted Wi-Fi. Use your phone's cellular data or a personal hotspot instead. (NSA – Securing Wireless Devices in Public Settings (July 2021, PDF; public copy hosted by InfraGard LA))
  2. If you must use public Wi-Fi, NSA strongly advises using a VPN, and only HTTPS websites. (NSA – Securing Wireless Devices in Public Settings (July 2021, PDF; public copy hosted by InfraGard LA))
  3. Never click past a certificate or security warning. Close the page. (NSFR safety advice.)
  4. Forget public networks and turn off auto-join (see "Turn it off" above).
  5. From a trusted device and connection: change your passwords, sign out of all sessions and devices, and turn on multifactor authentication. (CISA – Turn on MFA)

Protecting vulnerable adults

Older adults and adults with disabilities can be targeted by strangers, and sometimes, painfully, by people they trust: family members, caregivers, or someone holding a power of attorney. If you're worried about someone, you don't need proof to ask for help.

Warning signs to watch for

  • Sudden or unusual withdrawals, transfers, or new cards.
  • A new "friend", romantic interest, or helper who takes a strong interest in their money.
  • Bills going unpaid when there should be enough money.

Crypto ATM and impersonation scams

Scammers posing as tech support, a bank, or the government may tell someone to take out cash and put it into a cryptocurrency ATM, or hand it to a courier. (FBI IC3 PSA – “Phantom Hacker” scams target senior citizens (Sept. 29, 2023), FBI IC3 PSA I-012924-PSA – Scammers use couriers to retrieve cash and precious metals (Jan. 29, 2024)) In 2024 the IC3 received 10,956 complaints with $246.7 million in losses involving cryptocurrency ATMs/kiosks.

Real cases and what they teach

Facts below come only from the cited official documents.

City of Dallas ransomware, May 2023

According to the city's after-action report, the Royal group got in on April 7, 2023, using a service account, spent weeks inside, took an estimated 1.169 TB of data, and began encrypting servers early on May 3, 2023. The city reported that personal information of 26,212 Texas residents and 30,253 individuals in total was potentially exposed. Lesson: attackers may be inside long before the ransom note appears; protect logins and keep offline backups. (City of Dallas – After-Action Report, May 2023 ransomware incident (PDF))

Scattered Spider, 2023–2025

A joint CISA/FBI advisory describes a group that posed as IT help-desk staff, talked people into sharing one-time codes, used repeated MFA prompts ("MFA fatigue"), and used SIM swaps. Lesson: never share a code or approve a prompt you didn't start. (CISA/FBI advisory AA23-320A – Scattered Spider)

Classic attacks

ILOVEYOU ("Love Letter") worm, May 2000

CERT/CC reported an email with the subject "ILOVEYOU" and an attachment named "LOVE-LETTER-FOR-YOU.TXT.VBS". When opened, it mailed itself to everyone in the victim's Outlook address books and overwrote many files. By May 8, 2000, CERT/CC had reports from more than 650 sites indicating more than 500,000 systems affected. People who received it "will most likely recognize the sender". Lesson: don't open unexpected attachments, even from people you know. (CERT Advisory CA-2000-04 Love Letter Worm (Internet Archive copy))

Nimda worm ("readme.exe"), September 2001

CERT/CC reported a worm spreading by email with an attachment named "readme.exe", through shared folders (copies named README.EML), through infected websites, and by attacking unpatched web servers. On vulnerable systems, just opening or previewing the email could run it. Lesson: keep systems updated, and don't open unexpected attachments. (CERT Advisory CA-2001-26 Nimda Worm (archived copy))
