Several Apple customers recently reported being targeted in elaborate phishing attacks that involve what appears to be a bug in Apple’s password reset feature. In this scenario, a target’s Apple devices are forced to display dozens of system-level prompts that prevent the devices from being used until the recipient responds “Allow” or “Don’t Allow” to each prompt. Assuming the user manages not to fat-finger the wrong button on the umpteenth password reset request, the scammers will then call the victim while spoofing Apple support in the caller ID, saying the user’s account is under attack and that Apple support needs to “verify” a one-time code.
Some of the many notifications Patel says he received from Apple all at once.
Parth Patel is an entrepreneur who is trying to build a startup in the conversational AI space. On March 23, Patel documented on Twitter/X a recent phishing campaign targeting him that involved what’s known as a “push bombing” or “MFA fatigue” attack, wherein the phishers abuse a feature or weakness of a multi-factor authentication (MFA) system in a way that inundates the target’s device(s) with alerts to approve a password change or login.
“All of my devices started blowing up, my watch, laptop and phone,” Patel told KrebsOnSecurity. “It was like this system notification from Apple to approve [a reset of the account password], but I couldn’t do anything else with my phone. I had to go through and decline like 100-plus notifications.”
Some people confronted with such a deluge may eventually click “Allow” to the incessant password reset prompts — just so they can use their phone again. Others may inadvertently approve one of these prompts, which will also appear on a user’s Apple watch if they have one.
But the attackers in this campaign had an ace up their sleeves: Patel said after denying all of the password reset prompts from Apple, he received a call on his iPhone that said it was from Apple Support (the number displayed was 1-800-275-2273, Apple’s real customer support line).
“I pick up the phone and I’m super suspicious,” Patel recalled. “So I ask them if they can verify some information about me, and after hearing some aggressive typing on his end he gives me all this information about me and it’s totally accurate.”
All of it, that is, except his real name. Patel said when he asked the fake Apple support rep to validate the name they had on file for the Apple account, the caller gave a name that was not his but rather one that Patel has only seen in background reports about him that are for sale at a people-search website called PeopleDataLabs.
Patel said he has worked fairly hard to remove his information from multiple people-search websites, and he found PeopleDataLabs uniquely and consistently listed this inaccurate name as an alias on his consumer profile.
“For some reason, PeopleDataLabs has three profiles that come up when you search for my info, and two of them are mine but one is an elementary school teacher from the midwest,” Patel said. “I asked them to verify my name and they said Anthony.”
Patel said the goal of the voice phishers is to trigger an Apple ID reset code to be sent to the user’s device, which is a text message that includes a one-time password. If the user supplies that one-time code, the attackers can then reset the password on the account and lock the user out. They can also then remotely wipe all of the user’s Apple devices.
Chris is a cryptocurrency hedge fund owner who asked that only his first name be used so as not to paint a bigger target on himself. Chris told KrebsOnSecurity he experienced a remarkably similar phishing attempt in late February.
“The first alert I got I hit ‘Don’t Allow’, but then right after that I got like 30 more notifications in a row,” Chris said. “I figured maybe I sat on my phone weird, or was accidentally pushing some button that was causing these, and so I just denied them all.”
Chris says the attackers persisted hitting his devices with the reset notifications for several days after that, and at one point he received a call on his iPhone that said it was from Apple support.
“I said I would call them back and hung up,” Chris said, demonstrating the proper response to such unbidden solicitations. “When I called back to the real Apple, they couldn’t say whether anyone had been in a support call with me just then. They just said Apple states very clearly that it will never initiate outbound calls to customers — unless the customer requests to be contacted.”
Massively freaking out that someone was trying to hijack his digital life, Chris said he changed his passwords and then went to an Apple store and bought a new iPhone. From there, he created a new Apple iCloud account using a brand new email address.
Chris said he then proceeded to get even more system alerts on his new iPhone and iCloud account — all the while still sitting at the local Apple Genius Bar.
Chris told KrebsOnSecurity his Genius Bar tech was mystified about the source of the alerts, but Chris said he suspects that whatever the phishers are abusing to rapidly generate these Apple system alerts requires knowing the phone number on file for the target’s Apple account. After all, that was the only aspect of Chris’s new iPhone and iCloud account that hadn’t changed.
“Ken” is a security industry veteran who spoke on condition of anonymity. Ken said he first began receiving these unsolicited system alerts on his Apple devices earlier this year, but that he has not received any phony Apple support calls as others have reported.
“This recently happened to me in the middle of the night at 12:30 a.m.,” Ken said. “And even though I have my Apple watch set to remain quiet during the time I’m usually sleeping at night, it woke me up with one of these alerts. Thank god I didn’t press ‘Allow,’ which was the first option shown on my watch. I had to scroll watch the wheel to see and press the ‘Don’t Allow’ button.”
Ken shared this photo he took of an alert on his watch that woke him up at 12:30 a.m. Ken said he had to scroll on the watch face to see the “Don’t Allow” button.
Ken didn’t know it when all this was happening (and it’s not at all obvious from the Apple prompts), but clicking “Allow” would not have allowed the attackers to change Ken’s password. Rather, clicking “Allow” displays a six digit PIN that must be entered on Ken’s device — allowing Ken to change his password. It appears that these rapid password reset prompts are being used to make a subsequent inbound phone call spoofing Apple more believable.
Ken said he contacted the real Apple support and was eventually escalated to a senior Apple engineer. The engineer assured Ken that turning on an Apple Recovery Key for his account would stop the notifications once and for all.
A recovery key is an optional security feature that Apple says “helps improve the security of your Apple ID account.” It is a randomly generated 28-character code, and when you enable a recovery key it is supposed to disable Apple’s standard account recovery process. The thing is, enabling it is not a simple process, and if you ever lose that code in addition to all of your Apple devices you will be permanently locked out.
Ken said he enabled a recovery key for his account as instructed, but that it hasn’t stopped the unbidden system alerts from appearing on all of his devices every few days.
KrebsOnSecurity tested Ken’s experience, and can confirm that enabling a recovery key does nothing to stop a password reset prompt from being sent to associated Apple devices. Visiting Apple’s “forgot password” page — https://iforgot.apple.com — asks for an email address and for the visitor to solve a CAPTCHA.
After that, the page will display the last two digits of the phone number tied to the Apple account. Filling in the missing digits and hitting submit on that form will send a system alert, whether or not the user has enabled an Apple Recovery Key.

What sanely designed authentication system would send dozens of requests for a password change in the span of a few moments, when the first requests haven’t even been acted on by the user? Could this be the result of a bug in Apple’s systems?
Apple has not yet responded to requests for comment.
Throughout 2022, a criminal hacking group known as LAPSUS$ used MFA bombing to great effect in intrusions at Cisco, Microsoft and Uber. In response, Microsoft began enforcing “MFA number matching,” a feature that displays a series of numbers to a user attempting to log in with their credentials. These numbers must then be entered into the account owner’s Microsoft authenticator app on their mobile device to verify they are logging into the account.
Kishan Bagaria is a hobbyist security researcher and engineer who founded the website texts.com (now owned by Automattic), and he’s convinced Apple has a problem on its end. In August 2019, Bagaria reported to Apple a bug that allowed an exploit he dubbed “AirDoS” because it could be used to let an attacker infinitely spam all nearby iOS devices with a system-level prompt to share a file via AirDrop — a file-sharing capability built into Apple products.
Apple fixed that bug nearly four months later in December 2019, thanking Bagaria in the associated security bulletin. Bagaria said Apple’s fix was to add stricter rate limiting on AirDrop requests, and he suspects that someone has figured out a way to bypass Apple’s rate limit on how many of these password reset requests can be sent in a given timeframe.
“I think this could be a legit Apple rate limit bug that should be reported,” Bagaria said.
Apple seems requires a phone number to be on file for your account, but after you’ve set up the account it doesn’t have to be a mobile phone number. KrebsOnSecurity’s testing shows Apple will accept a VOIP number (like Google Voice). So, changing your account phone number to a VOIP number that isn’t widely known would be one mitigation here.
One caveat with the VOIP number idea: Unless you include a real mobile number, Apple’s iMessage and Facetime applications will be disabled for that device. This might a bonus for those concerned about reducing the overall attack surface of their Apple devices, since zero-click zero-days in these applications have repeatedly been used by spyware purveyors.
Also, it appears Apple’s password reset system will accept and respect email aliases. Adding a “+” character after the username portion of your email address — followed by a notation specific to the site you’re signing up at — lets you create an infinite number of unique email addresses tied to the same account.
For instance, if I were signing up at example.com, I might give my email address as krebsonsecurity+example@gmail.com. Then, I simply go back to my inbox and create a corresponding folder called “Example,” along with a new filter that sends any email addressed to that alias to the Example folder. In this case, however, perhaps a less obvious alias than “+apple” would be advisable.
Update, March 27, 5:06 p.m. ET: Added perspective on Ken’s experience. Also included a What Can You Do? section.
It’s not unusual for the data brokers behind people-search websites to use pseudonyms in their day-to-day lives (you would, too). Some of these personal data purveyors even try to reinvent their online identities in a bid to hide their conflicts of interest. But it’s not every day you run across a US-focused people-search network based in China whose principal owners all appear to be completely fabricated identities.
Responding to a reader inquiry concerning the trustworthiness of a site called TruePeopleSearch[.]net, KrebsOnSecurity began poking around. The site offers to sell reports containing photos, police records, background checks, civil judgments, contact information “and much more!” According to LinkedIn and numerous profiles on websites that accept paid article submissions, the founder of TruePeopleSearch is Marilyn Gaskell from Phoenix, Ariz.
The saucy yet studious LinkedIn profile for Marilyn Gaskell.
Ms. Gaskell has been quoted in multiple “articles” about random subjects, such as this article at HRDailyAdvisor about the pros and cons of joining a company-led fantasy football team.
“Marilyn Gaskell, founder of TruePeopleSearch, agrees that not everyone in the office is likely to be a football fan and might feel intimidated by joining a company league or left out if they don’t join; however, her company looked for ways to make the activity more inclusive,” this paid story notes.
Also quoted in this article is Sally Stevens, who is cited as HR Manager at FastPeopleSearch[.]io.

“Fantasy football provides one way for employees to set aside work matters for some time and have fun,” Stevens contributed. “Employees can set a special league for themselves and regularly check and compare their scores against one another.”
Imagine that: Two different people-search companies mentioned in the same story about fantasy football. What are the odds?
Both TruePeopleSearch and FastPeopleSearch allow users to search for reports by first and last name, but proceeding to order a report prompts the visitor to purchase the file from one of several established people-finder services, including BeenVerified, Intelius, and Spokeo.
DomainTools.com shows that both TruePeopleSearch and FastPeopleSearch appeared around 2020 and were registered through Alibaba Cloud, in Beijing, China. No other information is available about these domains in their registration records, although both domains appear to use email servers based in China.
Sally Stevens’ LinkedIn profile photo is identical to a stock image titled “beautiful girl” from Adobe.com. Ms. Stevens is also quoted in a paid blog post at ecogreenequipment.com, as is Alina Clark, co-founder and marketing director of CocoDoc, an online service for editing and managing PDF documents.
The profile photo for Alina Clark is a stock photo appearing on more than 100 websites.
Scouring multiple image search sites reveals Ms. Clark’s profile photo on LinkedIn is another stock image that is currently on more than 100 different websites, including Adobe.com. Cocodoc[.]com was registered in June 2020 via Alibaba Cloud Beijing in China.
The same Alina Clark and photo materialized in a paid article at the website Ceoblognation, which in 2021 included her at #11 in a piece called “30 Entrepreneurs Describe The Big Hairy Audacious Goals (BHAGs) for Their Business.” It’s also worth noting that Ms. Clark is currently listed as a “former Forbes Council member” at the media outlet Forbes.com.
Entrepreneur #6 is Stephen Curry, who is quoted as CEO of CocoSign[.]com, a website that claims to offer an “easier, quicker, safer eSignature solution for small and medium-sized businesses.” Incidentally, the same photo for Stephen Curry #6 is also used in this “article” for #22 Jake Smith, who is named as the owner of a different company.
Stephen Curry, aka Jake Smith, aka no such person.
Mr. Curry’s LinkedIn profile shows a young man seated at a table in front of a laptop, but an online image search shows this is another stock photo. Cocosign[.]com was registered in June 2020 via Alibaba Cloud Beijing. No ownership details are available in the domain registration records.
Listed at #13 in that 30 Entrepreneurs article is Eden Cheng, who is cited as co-founder of PeopleFinderFree[.]com. KrebsOnSecurity could not find a LinkedIn profile for Ms. Cheng, but a search on her profile image from that Entrepreneurs article shows the same photo for sale at Shutterstock and other stock photo sites.
DomainTools says PeopleFinderFree was registered through Alibaba Cloud, Beijing. Attempts to purchase reports through PeopleFinderFree produce a notice saying the full report is only available via Spokeo.com.
Lynda Fairly is Entrepreneur #24, and she is quoted as co-founder of Numlooker[.]com, a domain registered in April 2021 through Alibaba in China. Searches for people on Numlooker forward visitors to Spokeo.
The photo next to Ms. Fairly’s quote in Entrepreneurs matches that of a LinkedIn profile for Lynda Fairly. But a search on that photo shows this same portrait has been used by many other identities and names, including a woman from the United Kingdom who’s a cancer survivor and mother of five; a licensed marriage and family therapist in Canada; a software security engineer at Quora; a journalist on Twitter/X; and a marketing expert in Canada.
Cocofinder[.]com is a people-search service that launched in Sept. 2019, through Alibaba in China. Cocofinder lists its market officer as Harriet Chan, but Ms. Chan’s LinkedIn profile is just as sparse on work history as the other people-search owners mentioned already. An image search online shows that outside of LinkedIn, the profile photo for Ms. Chan has only ever appeared in articles at pay-to-play media sites, like this one from outbackteambuilding.com.
Perhaps because Cocodoc and Cocosign both sell software services, they are actually tied to a physical presence in the real world — in Singapore (15 Scotts Rd. #03-12 15, Singapore). But it’s difficult to discern much from this address alone.
Who’s behind all this people-search chicanery? A January 2024 review of various people-search services at the website techjury.com states that Cocofinder is a wholly-owned subsidiary of a Chinese company called Shenzhen Duiyun Technology Co.
“Though it only finds results from the United States, users can choose between four main search methods,” Techjury explains. Those include people search, phone, address and email lookup. This claim is supported by a Reddit post from three years ago, wherein the Reddit user “ProtectionAdvanced” named the same Chinese company.
Is Shenzhen Duiyun Technology Co. responsible for all these phony profiles? How many more fake companies and profiles are connected to this scheme? KrebsOnSecurity found other examples that didn’t appear directly tied to other fake executives listed here, but which nevertheless are registered through Alibaba and seek to drive traffic to Spokeo and other data brokers. For example, there’s the winsome Daniela Sawyer, founder of FindPeopleFast[.]net, whose profile is flogged in paid stories at entrepreneur.org.
Google currently turns up nothing else for in a search for Shenzhen Duiyun Technology Co. Please feel free to sound off in the comments if you have any more information about this entity, such as how to contact it. Or reach out directly at krebsonsecurity @ gmail.com.

It appears the purpose of this network is to conceal the location of people in China who are seeking to generate affiliate commissions when someone visits one of their sites and purchases a people-search report at Spokeo, for example. And it is clear that Spokeo and others have created incentives wherein anyone can effectively white-label their reports, and thereby make money brokering access to peoples’ personal information.
Spokeo’s Wikipedia page says the company was founded in 2006 by four graduates from Stanford University. Spokeo co-founder and current CEO Harrison Tang has not yet responded to requests for comment.
Intelius is owned by San Diego based PeopleConnect Inc., which also owns Classmates.com, USSearch, TruthFinder and Instant Checkmate. PeopleConnect Inc. in turn is owned by H.I.G. Capital, a $60 billion private equity firm. Requests for comment were sent to H.I.G. Capital. This story will be updated if they respond.
BeenVerified is owned by a New York City based holding company called The Lifetime Value Co., a marketing and advertising firm whose brands include PeopleLooker, NeighborWho, Ownerly, PeopleSmart, NumberGuru, and Bumper, a car history site.
Ross Cohen, chief operating officer at The Lifetime Value Co., said it’s likely the network of suspicious people-finder sites was set up by an affiliate. Cohen said Lifetime Value would investigate to determine if this particular affiliate was driving them any sign-ups.
All of the above people-search services operate similarly. When you find the person you’re looking for, you are put through a lengthy (often 10-20 minute) series of splash screens that require you to agree that these reports won’t be used for employment screening or in evaluating new tenant applications. Still more prompts ask if you are okay with seeing “potentially shocking” details about the subject of the report, including arrest histories and photos.
Only at the end of this process does the site disclose that viewing the report in question requires signing up for a monthly subscription, which is typically priced around $35. Exactly how and from where these major people-search websites are getting their consumer data — and customers — will be the subject of further reporting here.
The main reason these various people-search sites require you to affirm that you won’t use their reports for hiring or vetting potential tenants is that selling reports for those purposes would classify these firms as consumer reporting agencies (CRAs) and expose them to regulations under the Fair Credit Reporting Act (FCRA).
These data brokers do not want to be treated as CRAs, and for this reason their people search reports typically don’t include detailed credit histories, financial information, or full Social Security Numbers (Radaris reports include the first six digits of one’s SSN).
But in September 2023, the U.S. Federal Trade Commission found that TruthFinder and Instant Checkmate were trying to have it both ways. The FTC levied a $5.8 million penalty against the companies for allegedly acting as CRAs because they assembled and compiled information on consumers into background reports that were marketed and sold for employment and tenant screening purposes.
The FTC also found TruthFinder and Instant Checkmate deceived users about background report accuracy. The FTC alleges these companies made millions from their monthly subscriptions using push notifications and marketing emails that claimed that the subject of a background report had a criminal or arrest record, when the record was merely a traffic ticket.
The FTC said both companies deceived customers by providing “Remove” and “Flag as Inaccurate” buttons that did not work as advertised. Rather, the “Remove” button removed the disputed information only from the report as displayed to that customer; however, the same item of information remained visible to other customers who searched for the same person.
The FTC also said that when a customer flagged an item in the background report as inaccurate, the companies never took any steps to investigate those claims, to modify the reports, or to flag to other customers that the information had been disputed.
There are a growing number of online reputation management companies that offer to help customers remove their personal information from people-search sites and data broker databases. There are, no doubt, plenty of honest and well-meaning companies operating in this space, but it has been my experience that a great many people involved in that industry have a background in marketing or advertising — not privacy.
Also, some so-called data privacy companies may be wolves in sheep’s clothing. On March 14, KrebsOnSecurity published an abundance of evidence indicating that the CEO and founder of the data privacy company OneRep.com was responsible for launching dozens of people-search services over the years.
Finally, some of the more popular people-search websites are notorious for ignoring requests from consumers seeking to remove their information, regardless of which reputation or removal service you use. Some force you to create an account and provide more information before you can remove your data. Even then, the information you worked hard to remove may simply reappear a few months later.
This aptly describes countless complaints lodged against the data broker and people search giant Radaris. On March 8, KrebsOnSecurity profiled the co-founders of Radaris, two Russian brothers in Massachusetts who also operate multiple Russian-language dating services and affiliate programs.
The truth is that these people-search companies will continue to thrive unless and until Congress begins to realize it’s time for some consumer privacy and data protection laws that are relevant to life in the 21st century. Duke University adjunct professor Justin Sherman says virtually all state privacy laws exempt records that might be considered “public” or “government” documents, including voting registries, property filings, marriage certificates, motor vehicle records, criminal records, court documents, death records, professional licenses, bankruptcy filings, and more.
“Consumer privacy laws in California, Colorado, Connecticut, Delaware, Indiana, Iowa, Montana, Oregon, Tennessee, Texas, Utah, and Virginia all contain highly similar or completely identical carve-outs for ‘publicly available information’ or government records,” Sherman said.

Communities like Craigslist, OfferUp, Facebook Marketplace and others are great for finding low- or no-cost stuff that one can pick up directly from a nearby seller, and for getting rid of useful things that don’t deserve to end up in a landfill. But when dealing with strangers from the Internet, there is always a risk that the person you’ve agreed to meet has other intentions.
Nearly all U.S. states now have designated safe trading stations — mostly at local police departments — which ensure that all transactions are handled in plain view of both the authorities and security cameras.
These safe trading places exist because sometimes in-person transactions from the Internet don’t end well for one or more parties involved. The website Craigslistkillers has catalogued news links for at least 132 murders linked to Craigslist transactions since 2015. Many of these killings involved high-priced items like automobiles and consumer electronics, where the prospective buyer apparently intended all along to kill the owner and steal the item offered for sale. Others were motivated simply by a desire to hurt people.
This is not to say that using Craigslist is uniquely risky or dangerous; I’m sure the vast majority of transactions generated by the site end amicably and without physical violence. And that probably holds true for all of Craigslist’s competitors.
Still, the risk of a deal going badly when one meets total strangers from the Internet is not zero, and so it’s only sensible to take a few simple precautions. For example, choosing to transact at a designated safe place such as a police station dramatically reduces the likelihood that anyone wishing you harm would even show up.
I recently stumbled upon one of these designated exchange places by accident, hence my interest in learning more about them. The one I encountered was at a Virginia county sheriff’s office, and it has two parking spots reserved with a sign that reads, “Internet Purchase & Exchange Location: This Area is Under 24 Hour Video Surveillance” [image above].
According to the list maintained at Safetradestations.com, there are four other such designated locations in Northern Virginia. And it appears most states now have them in at least some major cities. Safeexchangepoint.com also has a searchable index of safe trading locations in the United States and Canada.
Granted, not everyone is going to live close to one of these designated trading stations. Or maybe what you want to buy, sell or trade you’d rather not have recorded in front of police cameras. Either way, here are a few tips on staying safe while transacting in real life with strangers from the Internet (compliments of the aforementioned safe trading websites).
The safest exchange points are easily accessible and in a well-lit, public place where transactions are visible to others nearby. Try to arrange a meeting time that is during daylight hours, and consider bringing a friend along — especially when dealing with high-value items like laptops and smart phones.
Safeexchangepoint.com also advises that police or merchants that host their own exchange locations generally won’t get involved in the details of your transaction unless specified otherwise, and that many police departments (but not all) are willing to check the serial number of an item for sale to make sure it’s not known to be stolen property.
Of course, it’s not always practical or possible to haul that old sofa to the local police department, or a used car that isn’t working. In those situations, safetradestations.com has some decent suggestions:
