The United Parcel Service (UPS) says fraudsters have been harvesting cellphone numbers and different info from its on-line cargo monitoring device in Canada to ship extremely focused SMS phishing (a.ok.a. “smishing”) messages that spoofed UPS and different high manufacturers. The missives addressed recipients by identify, included particulars about latest orders, and warned that these orders wouldn’t be shipped except the shopper paid an added supply charge.
In a snail mail letter despatched this month to Canadian prospects, UPS Canada Ltd. mentioned it’s conscious that some bundle recipients have obtained fraudulent textual content messages demanding fee earlier than a bundle will be delivered, and that it has been working with companions in its supply chain to attempt to perceive how the fraud was occurring.
The latest letter from UPS about SMS phishers harvesting cargo particulars and cellphone numbers from its web site.
“During that review, UPS discovered a method by which a person who searched for a particular package or misused a package look-up tool could obtain more information about the delivery, potentially including a recipient’s phone number,” the letter reads. “Because this information could be misused by third parties, including potentially in a smishing scheme, UPS has taken steps to limit access to that information.”
The written discover goes on to say UPS believes the info publicity “affected packages for a small group of shippers and some of their customers from February 1, 2022 to April 24, 2023.”
As early as April 2022, KrebsOnSecurity started receiving ideas from Canadian readers who have been puzzling over why they’d simply obtained one in all these SMS phishing messages that referenced info from a latest order they’d legitimately positioned at a web based retailer.
In March, 2023, a reader named Dylan from British Columbia wrote in to say he’d obtained one in all these delivery charge rip-off messages not lengthy after inserting an order to purchase gobs of constructing blocks instantly from Lego.com. The message included his full identify, cellphone quantity, and postal code, and urged him to click on a hyperlink to mydeliveryfee-ups[.]data and pay a $1.55 supply charge that was supposedly required to ship his Legos.
“From searching the text of this phishing message, I can see that a lot of people have experienced this scam, which is more convincing because of the information the phishing text contains,” Dylan wrote. “It seems likely to me that UPS is leaking information somehow about upcoming deliveries.”
Josh is a reader who works for a corporation that ships merchandise to Canada, and in early January 2023 he inquired whether or not there was any details about a breach at UPS Canada.
“We’ve seen many of our customers targeted with a fraudulent UPS text message scheme after placing an order,” Josh mentioned. “A link is provided (often only after the customer responds to the text) which takes you to a captcha page, followed by a fraudulent payment collection page.”
Pivoting on the area within the smishing message despatched to Dylan exhibits the phishing area shared an Internet host in Russia [91.215.85-166] with practically two dozen different smishing associated domains, together with upsdelivery[.]data, legodelivery[.]data, adidascanadaltd[.]com, crocscanadafee[.]data, refw0234apple[.]data, vista-printcanada[.]data and telus-ca[.]data.
The inclusion of big-name manufacturers within the domains of those UPS smishing campaigns suggests the perpetrators had the flexibility to focus their lookups on UPS prospects who had just lately ordered gadgets from particular corporations.
Attempts to go to these domains with an online browser failed, however loading them in a cell gadget (or in my case, emulating a cell gadget utilizing a digital machine and Developer Tools in Firefox) revealed the primary stage of this smishing assault. As Josh talked about, what first popped up was a CAPTCHA; after the customer solved the CAPTCHA, they have been taken by means of a number of extra pages that requested the consumer’s full identify, date of start, bank card quantity, handle, e-mail and cellphone quantity.
A smishing web site concentrating on Canadians who just lately bought from Adidas on-line. The web site would solely load in a cell browser.
In April 2022, KrebsOnSecurity heard from Alex, the CEO of a know-how firm in Canada who requested to depart his final identify out of this story. Alex reached out when he started receiving the smishing messages virtually instantly after ordering two units of Airpods instantly from Apple’s web site.
What puzzled Alex most was that he’d instructed Apple to ship the Airpods as a present to 2 completely different folks, and fewer than 24 hours later the cellphone quantity he makes use of for his Apple account obtained two of the phishing messages, each of which contained salutations that included the names of the folks for whom he’d purchased Airpods.
“I’d put the recipient as different people on my team, but because it was my phone number on both orders I was the one getting the texts,” Alex defined. “That same day, I got text messages referring to me as two different people, neither of whom were me.”
Alex mentioned he believes UPS Canada both doesn’t totally perceive what occurred but, or it’s being coy about what it is aware of. He mentioned the wording of UPS’s response misleadingly suggests the smishing assaults have been one way or the other the results of hackers randomly wanting up bundle info by way of the corporate’s monitoring web site.
Alex mentioned it’s doubtless that whoever is accountable discovered find out how to question the UPS Canada web site for less than pending orders from particular manufacturers, maybe by exploiting some kind of utility programming interface (API) that UPS Canada makes or made obtainable to its largest retail companions.
“It wasn’t like I put the order through [on Apple.ca] and some days or weeks later I got a targeted smishing attack,” he mentioned. “It was more or less the same day. And it was as if [the phishers] were being notified the order existed.”
The letter to UPS Canada prospects doesn’t point out whether or not another prospects in North America have been affected, and it stays unclear whether or not any UPS prospects outdoors of Canada could have been focused.
In a press release supplied to KrebsOnSecurity, Sandy Springs, Ga. based mostly UPS [NYSE:UPS] mentioned the corporate has been working with companions within the supply chain to know how that fraud was being perpetrated, in addition to with legislation enforcement and third-party specialists to determine the reason for this scheme and to place a cease to it.
“Law enforcement has indicated that there has been an increase in smishing impacting a number of shippers and many different industries,” reads an e-mail from Brian Hughes, director of economic and technique communications at UPS.
“Out of an abundance of caution, UPS is sending privacy incident notification letters to individuals in Canada whose information may have been impacted,” Hughes mentioned. “We encourage our customers and general consumers to learn about the ways they can stay protected against attempts like this by visiting the UPS Fight Fraud website.”
