Thanks FedEx, That is Why we Hold Getting Phished
I have been getting quite a lot of these “your parcel could not be delivered” phishing assaults currently and for those who’re a human with a cellphone, you most likely have been too. Simply as a quick reminder, they appear like this:
These get by all of the technical controls that exist at my telco they usually land smack bang in my SMS inbox. Nonetheless, I do not fall for the scams as a result of I search for the warning indicators: a way of urgency, worry of lacking out, and unusual URLs that look nothing like all parcel supply service I do know of. They’ve a fairly tough go of convincing me they’re from Australia Put up by placing “auspost” someplace or different inside every hyperlink, however I am a wise human so I do not fall for this (that is a joke, read why humans are bad at URLs).
Nonetheless… I am anticipating a parcel. It is effectively into the 2020’s and submit COVID so I am at all times anticipating a parcel, as a result of that is simply how we purchase stuff lately. And so, once I acquired the next SMS earlier this week I used to be anticipating a parcel and I used to be anticipating phishing assaults:
So… which is it? Parcel or phish? Let’s examine what the individuals say:
Referring to the father or mother tweet, is that this message legit and will I pay the obligation and taxes?

Whoa – that is an 87% “dodgy AF” vote from over 4,000 respondents so yeah, that is fairly emphatic. Why such an overwhelmingly suspicious crowd? Let’s break that message down into 7 “dodgy AF” indicators:
- Phishers generally make typos of their messaging and I do know “FedEx” at all times capitalises the “E”. And what’s with the “-Exp”? Dodgy AF!
- Why does the cargo quantity look so brief? And why is it similar to the requested fee beneath? Dodgy AF!
- Ah, so it is pressing is it? Urgency is a core tenet of social engineering because it encourages individuals to behave with out correctly pondering it although. Dodgy AF!
- Why are the “D” and the “T” capitalised? Dodgy AF!
- It is a US-headquartered international supply parcel service, why aren’t they telling me the forex? And even utilizing a greenback signal? Dodgy AF!
- Does this even want explaining? What’s this “bpoint.com.au” service? It is positively not a FedEx area nor an Aussie gov one if we’re speaking obligation and taxes. Dodgy AF!
- So… you are going to offer me the contact particulars for any “question” (not “queries”, so there’s one other grammatical purple flag), the very practice we’re now moving away from for one easy purpose: as a result of it is dodgy AF!
And so, I used to be with the 87% of different individuals. Nonetheless… I used to be anticipating a package deal. From FedEx. Coming from outdoors Australia so it could appeal to obligation and taxes. And I actually need to get this package deal as a result of it is a new 3D printer from Prusa, they usually’re superior!
There is a sage piece of recommendation that is at all times related in these instances and it is quite simple: if unsure, go the web site in query and confirm the request your self. So, I went to the acquisition affirmation from Prusa, discovered the transport particulars and adopted the hyperlink to the FedEx web site. Now it was merely a matter of discovering the part that talks about tax, besides…
Dodgy. A. F.
I went all by that web page and could not discover a single reference to obligation, nor for something tax associated. Attempt as I’d, I could not set up the authenticity of the SMS by going on to the (alleged) supply. However what I may simply set up is that for those who observe that hyperlink within the URL, you’ll be able to change the monitoring quantity, the client title and the quantity to utterly something you need!
That is all finished by merely altering the URL parameters; I am not modifying the browser DoM or intercepting site visitors or doing something fancy, it is actually simply question string parameter tampering mirrored XSS model. This looks like each phishing website ever, not a fee service run by Australia’s largest financial institution. Significantly, BPOINT is provided by the Commonwealth Bank and after the expertise above, I am on the level of reaching out to them and making a disclosure. Besides that that is how the system was clearly designed to work and it is a fully parallel subject to phishy FedEx SMSs. Talking of which, the very subsequent morning I obtained one other one from the identical sender:
I do not know if this makes it higher or worse 🤦♂️ Let’s simply leap into the highlights, each good and unhealthy:
- My transport quantity is now really within the textual content of the e-mail – yay!
- The phrases “obligation” and “taxes” at the moment are represented within the appropriate case – yay!
- The phrases “PAY NOW” are capitalised which appears… dodgy AF!
- And my favorite little bit of all: the “hyperlink” is not really a hyperlink in any respect as a result of it comprises no scheme, no area and no path, simply the question string parameters! Dodgy AF!
It is fairly unbelievable what they’ve finished with the hyperlink as a result of it makes the SMS solely unactionable. It is inconceivable to click on wherever and pay the cash. And whereas I am right here, why are all of the question string parameter names now capitalised? It is like there is a fully totally different (damaged) course of someplace producing these hyperlinks. Or scammers simply aren’t constant…
As a result of “dodgy AF” is the prevailing theme, I wanted to dig deeper, so I looked for the 1800 quantity. One of many first outcomes was for a Reverse Australia page for that number which upon studying the primary 3 feedback, completely summed up the sentiment thus far:
And the extra you learn each on that website and different high hyperlinks within the search outcomes, the extra persons are completely confused concerning the legitimacy of the messages. There’s just one factor to do – name FedEx. Not by the quantity within the (nonetheless doubtlessly phishy) SMS, however relatively by way of the quantity on their web site. So, click on the “Assist” menu merchandise, all the way down to “Buyer Assist” and we end up here:
I am going to prevent the ache of studying the response that ensued, suffice to say that it solely referred to electronic mail communications and boiled all the way down to suggesting you learn the area of the sender. However I did handle to pin the system down on a cellphone quantity which as you may see, is totally totally different to the one within the SMS messages:
So, I name the quantity and observe the voice prompts, deciding on choices by way of the keypad to route me by to the obligation and taxes part. However ultimately, a number of steps deep into the method, the system stops responding to key presses! “1” does not work and neither does “2” so with no response, the identical message simply repeats. But it surely does supply another and solutions I name 132610. That is the quantity I referred to as within the first place to get caught on this infinite loop!
I strive once more, this time following a distinct collection of prompts that ultimately asks for a monitoring quantity after which proceeds to inform me exactly what the web site already does! But it surely additionally gives the choice to talk to a customer support operator and I am really promptly put by. The operator explains that my cargo is valued at US$799 which converts to AU$1,215.97 and it subsequently topic to some inbound charges. “Nice, however how a lot and does it match what’s within the phishy SMSs I’ve acquired?” He guarantees somebody will name be again shortly…
After which, out of the blue 3 days after the preliminary phishy SMS arrived, an electronic mail landed in my inbox:
The greenback determine, the BPOINT deal with and the messaging all lined up with the SMSs, however that is simply merely correlation and if somebody had each my cellphone quantity and electronic mail deal with they may simply try and phish each with the identical particulars. However then, I appeared on the attachment to the e-mail and located this:
IT’S THE MISSING LINK!!!
My full Prusa bill was hooked up together with the order quantity, value and transport particulars. In different phrases, 87% of you have been unsuitable 😲
On a extra critical word, Aussies alone are losing north of AU$3B annually to scams, and that is clearly solely a drop within the ocean in comparison with the worldwide scale of this downside. Our Australian Communications and Media Authority physique (ACMA) recently reported 336M blocked scam SMSs and technical controls like these are clearly nice, however absent from their reporting was the variety of rip-off messages they did not block. There’s a simple clarification for this omission: they merely do not know what number of are despatched. But when I have been to take a guess, they’ve merely blocked the tip of the iceberg. For this reason along with technical controls, we reply on human controls which suggests serving to individuals establish the patterns of a rip-off: requests for cash, a way of urgency, grammar and casing that is a bit off, add wanting URLs. You realize, stuff like this:
What makes this example so ridiculous is that whereas we’re all anticipating scammers making an attempt to mimic reliable organisations, FedEx is on the market imitating scammers! Right here we’re within the period of burgeoning AI-driven scams which can be changing into more and more exhausting for people to establish, and FedEx is like “right here, maintain my beer” as they one-up the scammers at their very own recreation and do an ideal job of being fully indistinguishable from them.
Ah effectively, as I finally lament in these conditions, it is a good time to be within the business 😊
