USPS Text Scammers Duped His Wife, So He Hacked Their Operation (wired.com) 61
Security researcher Grant Smith uncovered a large-scale smishing scam where scammers posing as the USPS tricked victims into providing their credit card details through fake websites. Smith hacked into the scammers' systems, gathered evidence, and collaborated with the USPS and a US bank to protect over 438,000 unique credit cards from fraudulent activity. Wired reports: The flood of text messages started arriving early this year. They carried a similar thrust: The United States Postal Service is trying to deliver a parcel but needs more details, including your credit card number. All the messages pointed to websites where the information could be entered. Like thousands of others, security researcher Grant Smith got a USPS package message. Many of his friends had received similar texts. A couple of days earlier, he says, his wife called him and said she'd inadvertently entered her credit card details. With little going on after the holidays, Smith began a mission: Hunt down the scammers. Over the course of a few weeks, Smith tracked down the Chinese-language group behind the mass-smishing campaign, hacked into their systems, collected evidence of their activities, and started a months-long process of gathering victim data and handing it to USPS investigators and a US bank, allowing people's cards to be protected from fraudulent activity.
In total, people entered 438,669 unique credit cards into 1,133 domains used by the scammers, says Smith, a red team engineer and the founder of offensive cybersecurity firm Phantom Security. Many people entered multiple cards each, he says. More than 50,000 email addresses were logged, including hundreds of university email addresses and 20 military or government email domains. The victims were spread across the United States -- California, the state with the most, had 141,000 entries -- with more than 1.2 million pieces of information being entered in total. "This shows the mass scale of the problem," says Smith, who is presenting his findings at the Defcon security conference this weekend and previously published some details of the work. But the scale of the scamming is likely to be much larger, Smith says, as he didn't manage to track down all of the fraudulent USPS websites, and the group behind the efforts have been linked to similar scams in at least half a dozen other countries.

You may not be able to use that part of the evidence, but the actual operation probably does a lot more that wasn't touched, such as wire fraud for transferring the funds after the credit cards were used, posing as a federal (USPS) agent. That's why you generally get multiple charges on these kinds of events, even if some need to be dismissed, there will be others that stick.

It's only obvious to those of us who are in the IT industry / are deeply cynical and look hard at the email address being used etc etc. Most of the population are relatively ignorant and trusting; this is, on the whole, a good thing as the world works better as a result.
Despite being cynical and in IT, I fell for a scam once. It happened to refer to a delivery from a genuine company that I had received. After submitting the form I realised my mistake and had an embarrassing conversation with the security people at my credit card provider. Happily they were able to resolve the issue and didn't even feel the need to issue a new credit card. So let's not victim blame and remember that many computer users are older people who have no reason to be distrusting and probably nobody to warn them.

It's not, strictly speaking, a matter of trust: It's a question of "How does a credit card help the 'mailman'?" instead of asking, "How do I make this 'problem' disappear now, Now, NOW?" Then, the answer is obvious. You say you fell for it, but you realized quickly, the questions didn't relate to the problem. I imagine you failed to ask a similar question, "How does a credit-card help the package I already have?".

You're in a rush. Baby is screaming in the background, you're leaving tomorrow for vacation with the whole family and haven't even starting packing yet.
You actually have a genuine order that you're waiting delivery of.
Your article that you absolutely need before departing is delayed (with the poor tracking giving some generic "in transit" status).
This is an article from abroad, import tax is likely to be involved, and you know it's going to be complicated.
You finally receive an e-mail from the postal services asking you for the CC (for the import tax?)
e-mail visually looks like all the other from the postal service,
but in your rush you forget to check the parcel's tracking number (or it's shipped through some el-cheapo service that change tracking number 3 times along the way(*) and your post service support for such weird tracking is broken anyway)
and you don't check the destination URL which is actually your-post-service-com.actually-else.ru or worse, an actually hacked server belong to the same group à la wordpress-blog.your-post-service-com/hacked (This is way normally you never click buttons on e-mail, even genuine ones, but always navigate from the log-in page of the service. But today you're in a hurry, and clicking the short cut is tempting, and the official server is a pain to navigate **)
Also because you're in a hurry you didn't pay attention to some tell tale details, like the e-mail telling you to urgently pay the import tax or your parcel is going to be destroyed within a week,
or the import tax being ridiculously low (***),
(or depending of where you live, the wrong language/dialect and/or currency if your country of residence has multiple of those).
Obvious scams are only obvious to somebody who can calmly sit down and think it through, not completely in a rush.
Sound's like a very contrived example?
Hey, guess what Cory Doctorow him-self got scammed by abusing an "in the rush" situation [pluralistic.net].
(*): That's actually the case with some cheap Ali Express shipping options.
(**): My mom's bank has a web interface that is as fuggly as early hotmail dot com. She's not stupid, so she never clicks e-mail buttons. But it means that she needs to skype me or my brother for help whenever she needs to navigate this mess to find some function.
(***): I know that scammer ask first for ridiculously low sums in order to not trigger bank's full verification, but if you think that my postal service could charge "EUR 1,29"... you're two order of magnitude too low, and not even the right currency.

Yes, I was going to start this exact thread, but you beat me to it. I know my IQ is far below where I'd like it to be, but I only need to know 2 things, that the email describes some crisis or negative thing to scare me, and a link to click.

How these people click their way thru life and get taken advantage of is a mystery to me too.
A bit tougher is an email supposedly from a friend with a link to show some photos he's taken or other mildly interesting thing without the attempt to scare me. That's harder.
