“Believing the ‘Registered Mail Notice,’ Victims Call First.

The Story So Far

Letter Phishing on the Rise" Warning Issued Over "Letter Phishing" Scams Fake Notices Claiming "Registered Mail Could Not Be Delivered" Attached to Doors Scam Tactics Evolve, Now Involving Malicious App Installation and Video Call Demands A growing number of so-called "letter phishing" scams are once again causing concern, involving counterfeit stickers crafted to resemble official postal notices placed on front doors to trick victims into making phone calls themselves.^[1]

A scam tactic is spreading where counterfeit stickers resembling postal notices are posted on front doors to誘victims into calling directly. Screenshot from social media (SNS) View original imageAccording to reports from multiple media outlets on September 26, citing police sources, a voice phishing scheme is spreading in which criminals forge the Korea Post’s “Mail Delivery Notification” and attach the fake notice to apartment doors and mailboxes, thereby prompting victims to call the provided phone number.^[1]

Unlike typical voice phishing, where scammers initiate contact, letter phishing is characterized by the victim making the first call. According to the police, perpetrators design fake notices in a format similar to genuine ones, stating that “registered mail could not be delivered,” and include a phone number disguised as the mail carrier’s contact information.^[1]

When a victim calls the number, a scammer impersonating a mail carrier instructs the caller to contact another number under the pretext of reaching the relevant person in charge. Subsequently, someone posing as a prosecutor, police officer, or other investigative body claims the victim’s identity is linked to a criminal case, or that their bank account is involved with illegal funds, thereby pressuring the victim.^[1]

How to Spot & Avoid This Scam

This is what the approach actually looks like — study it before the list below:

How to Protect Yourself

• Verify any unexpected contact through a phone number or website you already know is real — never one the message itself provides.

If You Already Clicked or Replied

Responding to one of these is not the end of the story, and the first hour matters more than the mistake does. Work down this list in order:

1. Stop communicating with the sender. Do not send a final message explaining that you know it is a scam — that only confirms the number or address is live.
2. If you shared a password, change it everywhere you reused it, starting with email and banking. Reused passwords are how one disclosure becomes several.
3. If you shared card or bank details, call the number printed on your card and ask for the account to be flagged and reissued.
4. If you sent money by gift card, call the card issuer immediately — some balances can be frozen if the cards have not been drained yet.
5. Turn on two-factor authentication where it is offered, so a stolen password alone is not enough to get in.
6. Report it (see below). Reports are what let investigators connect one message to a wider campaign.

Where to Report It

• Federal Trade Commission — reportfraud.ftc.gov is the FTC’s own intake for fraud reports.^[2]
• FBI Internet Crime Complaint Center — ic3.gov handles internet-enabled crime, including losses already incurred.^[3]
• The impersonated organization — most banks and large platforms run their own abuse address; reporting there is what gets a fraudulent number or domain taken down.

What’s Disputed or Unconfirmed

This post reports what asiae.co.kr published and what a fixed detector matched in that text. It does not independently confirm the scale of the campaign, attribute it to anyone, or verify any figure the source reports. The example below the fold is a reconstruction built from the same reporting, not a captured message — so treat its wording as illustrative of the pattern, not as evidence of a specific message anyone received.

Kemetic Minds Analysis

Scam reporting tends to arrive as a list of things not to do, which puts the burden entirely on the person being targeted. The more useful read is structural: every tactic in the table above exists because it reliably beats a specific human default — trusting a familiar logo, acting fast under a deadline, believing a stranger who already seems to know something about you.

None of those defaults are failures of intelligence. They are the same instincts that make ordinary transactions possible. That is why “just be careful” does not work as advice, and why the one habit worth building is mechanical rather than judgmental: when a message asks for money, credentials, or speed, verify it through a channel you chose yourself. That single rule defeats every tactic listed above, without requiring you to spot which one you are looking at.
