Sammy Azdoufal claims he wasn’t trying to hack every robot vacuum in the world. He just wanted to remote control his brand-new DJI Romo vacuum with a PS5 gamepad, he tells The Verge, because it sounded fun.
Technology
The DJI Romo robovac had security so poor, this man remotely accessed thousands of them
But when his homegrown remote control app started talking to DJI’s servers, it wasn’t just one vacuum cleaner that replied. Roughly 7,000 of them, all around the world, began treating Azdoufal like their boss.
He could remotely control them, and look and listen through their live camera feeds, he tells me, saying he tested that out with a friend. He could watch them map out each room of a house, generating a complete 2D floor plan. He could use any robot’s IP address to find its rough location.
“I found my device was just one in an ocean of devices,” he says.
On Tuesday, when he showed me his level of access in a live demo, I couldn’t believe my eyes. Ten, hundreds, thousands of robots reporting for duty, each phoning home MQTT data packets every three seconds to say: their serial number, which rooms they’re cleaning, what they’ve seen, how far they’ve traveled, when they’re returning to the charger, and the obstacles they encountered along the way.
I watched each of these robots slowly pop into existence on a map of the world. Nine minutes after we began, Azdoufal’s laptop had already cataloged 6,700 DJI devices across 24 different countries and collected over 100,000 of their messages. If you add the company’s DJI Power portable power stations, which also phone home to these same servers, Azdoufal had access to over 10,000 devices.
When I say I couldn’t believe my eyes at first, I mean that literally. Azdoufal leads AI strategy at a vacation rental home company; when he told me he reverse engineered DJI’s protocols using Claude Code, I had to wonder whether AI was hallucinating these robots. So I asked my colleague Thomas Ricker, who just finished reviewing the DJI Romo, to pass us its serial number.
With nothing more than that 14-digit number, Azdoufal could not only pull up our robot, he could correctly see it was cleaning the living room and had 80 percent battery life remaining. Within minutes, I watched the robot generate and transmit an accurate floor plan of my colleague’s house, with the correct shape and size of each room, just by typing some digits into a laptop located in a different country.
Separately, Azdoufal pulled up his own DJI Romo’s live video feed, completely bypassing its security PIN, then walked into his living room and waved to the camera while I watched. He also says he shared a limited read-only version of his app with Gonzague Dambricourt, CTO at an IT consulting firm in France; Dambricourt tells me the app let him remotely watch his own DJI Romo’s camera feed before he even paired it.
Azdoufal was able to enable all of this without hacking into DJI’s servers, he claims. “I didn’t infringe any rules, I didn’t bypass, I didn’t crack, brute force, whatever.” He says he simply extracted his own DJI Romo’s private token — the key that tells DJI’s servers that you should have access to your own data — and those servers gave him the data of thousands of other people as well. He shows me that he can access DJI’s pre-production server, as well as the live servers for the US, China, and the EU.
Here’s the good news: On Tuesday, Azdoufal was not able to take our DJI Romo on a joyride through my colleague’s house, see through its camera, or listen through its microphone. DJI had already restricted that form of access after both Azdoufal and I told the company about the vulnerabilities.
And by Wednesday morning, Azdoufal’s scanner no longer had access to any robots, not even his own. It appears that DJI has plugged the gaping hole.
But this incident raises serious questions about DJI’s security and data practices. It will no doubt be used to help retroactively justify fears that led to the Chinese dronemaker getting largely forced out of the US. If Azdoufal could find these robots without even looking for them, will it protect them against people with intent to do harm? If Claude Code can spit out an app that lets you see into someone’s house, what keeps a DJI employee from doing so? And should a robot vacuum cleaner have a microphone? “It’s so weird to have a microphone on a freaking vacuum,” says Azdoufal.
It doesn’t help that when Azdoufal and The Verge contacted DJI about the issue, the company claimed it had fixed the vulnerability when it was actually only partially resolved.
“DJI can confirm the issue was resolved last week and remediation was already underway prior to public disclosure,” reads part of the original statement provided by DJI spokesperson Daisy Kong. We received that statement on Tuesday morning at 12:28PM ET — about half an hour before Azdoufal showed me thousands of robots, including our review unit, reporting for duty.
To be clear, it’s not surprising that a robot vacuum cleaner with a smartphone app would phone home to the cloud. For better or for worse, users currently expect those apps to work outside of their own homes. Unless you’ve built a tunnel into your own home network, that means relaying the data through cloud servers first.
But people who put a camera into their home expect that data to be protected, both in transit and once it reaches the server. Security professionals should know that — but as soon as Azdoufal connected to DJI’s MQTT servers, everything was visible in cleartext. If DJI has merely cut off one particular way into those servers, that may not be enough to protect them if hackers find another way in.
Unfortunately, DJI is far from the only smart home company that’s let people down on security. Hackers took over Ecovacs robot vacuums to chase pets and yell racist slurs in 2024. In 2025, South Korean government agencies reported that Dreame’s X50 Ultra had a flaw that could let hackers view its camera feed in real time, and that another Ecovacs and a Narwal robovac could let hackers view and steal photos from the devices. (Korea’s own Samsung and LG vacuums received high marks, and a Roborock did fine.)
It’s not just vacuums, of course. I still won’t buy a Wyze camera, despite its new security ideas, because that company tried to sweep a remote access vulnerability under the rug instead of warning its customers. I would find it hard to trust Anker’s Eufy after it lied to us about its security, too. But Anker came clean, and sunlight is a good disinfectant.
DJI is not being exceptionally transparent about what happened here, but it did answer almost all our questions. In a new statement to The Verge via spokesperson Daisy Kong, the company now admits “a backend permission validation issue” that could have theoretically let hackers see live video from its vacuums, and it admits that it didn’t fully patch that issue until after we confirmed that issues were still present.
Here’s that whole statement:
DJI identified a vulnerability affecting DJI Home through internal review in late January and initiated remediation immediately. The issue was addressed through two updates, with an initial patch deployed on February 8 and a follow-up update completed on February 10. The fix was deployed automatically, and no user action is required.
The vulnerability involved a backend permission validation issue affecting MQTT-based communication between the device and the server. While this issue created a theoretical potential for unauthorized access to live video of ROMO device, our investigation confirms that actual occurrences were extremely rare. Nearly all identified activity was linked to independent security researchers testing their own devices for reporting purposes, with only a handful of potential exceptions.
The first patch addressed this vulnerability but had not been applied universally across all service nodes. The second patch re-enabled and restarted the remaining service nodes. This has now been fully resolved, and there is no evidence of broader impact. This was not a transmission encryption issue. ROMO device-to-server communication was not transmitted in cleartext and has always been encrypted using TLS. Data associated with ROMO devices, such as those in Europe, is stored on U.S.-based AWS cloud infrastructure.
DJI maintains strong standards for data privacy and security and has established processes for identifying and addressing potential vulnerabilities. The company has invested in industry-standard encryption and operates a longstanding bug bounty program. We have reviewed the findings and recommendations shared by the independent security researchers who contacted us through that program as part of our standard post-remediation process. DJI will continue to implement additional security enhancements as part of its ongoing efforts.
Azdoufal says that even now, DJI hasn’t fixed all the vulnerabilities he’s found. One of them is the ability to view your own DJI Romo video stream without needing its security pin. Another one is so bad I won’t describe it until DJI has more time to fix it. DJI did not immediately promise to do so.
And both Azdoufal and security researcher Kevin Finisterre tell me it’s not enough for the Romo to send encrypted data to a US server, if anyone inside that server can easily read it afterward. “A server being based in the US in no way, shape, or form prevents .cn DJI employees from access,” Finisterre tells me. That seems evident, as Azdoufal lives in Barcelona and was able to see devices in entirely different regions.
“Once you’re an authenticated client on the MQTT broker, if there are no proper topic-level access controls (ACLs), you can subscribe to wildcard topics (e.g., #) and see all messages from all devices in plaintext at the application layer,” says Azdoufal. “TLS does nothing to prevent this — it only protects the pipe, not what’s inside the pipe from other authorized participants.”
When I tell Azdoufal that some may judge him for not giving DJI much time to resolve the issues before going public, he notes that he didn’t hack anything, didn’t expose sensitive data, and isn’t a security professional. He says he was simply livetweeting everything that happened while trying to control his robot with a PS5 gamepad.
“Yes, I don’t follow the rules, but people stick to the bug bounty program for money. I fucking don’t care, I just want this fixed,” he says. “Following the rules to the end would probably make this breach happen for a way longer time, I think.”
He doesn’t believe that DJI truly discovered these issues by itself back in January, and he’s annoyed the company only ever responded to him robotically in DMs on X, instead of answering his emails.
But he is happy about one thing: He can indeed control his Romo with a PlayStation or Xbox gamepad.

The Acer Nitro Blaze Link might run on Linux, but it’s no Steam Deck. Acer says it’s a “streaming-first handheld and companion device,” like a PlayStation Portal for your PC. Announced ahead of Computex on Friday, it’s launching in Q4 2026 with a 7-inch (1920 x 1200) display, Wi-Fi 6, just 1GB of LPDDR4 RAM, and 8GB of eMMC storage. That’s technically not even enough RAM to run Stardew Valley, but the Blaze Link isn’t meant for playing games locally.
Logitech launched a similar handheld a few years ago, the Logitech G Cloud, that cost $350, included 4GB of RAM and 64GB of storage, and ran on Android. It was a tough sell at that price considering that its performance was dependent on a good internet connection.
Acer hasn’t yet announced a price for the Nitro Blaze Link. But its specs suggest it could cost significantly less than proper handheld gaming PCs — which have been skyrocketing in price — potentially offering a more affordable and streaming-first alternative.
Correction, May 29th: The Nitro Blaze Link was announced ahead of Computex 2026, not at it.
NEWYou can now listen to Fox News articles!
It shows up in your junk folder with a subject line that practically yells at you: “ATTENTION 1!!!” That alone should raise suspicion. Still, the message quickly escalates. It claims to come from the IMF (International Monetary Fund) and says you are approved for a $4.5 million grant.
That is where things start to fall apart. This type of scam is designed to trigger both excitement and urgency. It also pushes you to hand over sensitive information before you stop to think.

NEW EMAIL SCAM USES HIDDEN CHARACTERS TO SLIP PAST FILTERS

The sender behind this IMF scam email
The email claims to be from the IMF. Yet the reply address is a Gmail account. That mismatch matters.
Legitimate financial institutions do not use free email services for official communication. They also do not ask you to reply to a personal inbox for something this serious.
Why the subject line is a warning sign
“ATTENTION 1!!!” is not how a global financial organization communicates. It is how scammers try to grab you fast.
Urgency lowers your guard. When you feel pressure, you are more likely to respond without verifying anything.
The greeting reveals a mass email
The message opens with “Attention: Sir/Madam.” If your name were truly selected for a multimillion-dollar payment, the sender would use it.
Generic greetings often mean the email was blasted out to thousands of people.
How the story tries to hook you
The email mentions debts tied to contracts, inheritance, lottery and loans. That wide net is intentional.
It increases the odds that something in the message feels familiar. Once that happens, the scam starts to feel personal.
The $4.5 million promise is the bait
The promise of $4.5 million is not random. Large numbers create excitement. They also make you more willing to overlook obvious problems.
Real financial grants do not appear out of nowhere like this.
YOUR EMAIL DIDN’T EXPIRE; IT’S JUST ANOTHER SNEAKY SCAM

Why scammers use real names
The email mentions IMF Managing Director Kristalina Georgieva. That sounds official, which is the point.
Scammers often include real names or titles to make fake messages feel credible. It is a shortcut to trust.
The writing and grammar feel off
Phrases like “Kindly reply me directly” and awkward sentence structure stand out. One odd sentence might not mean much. However, repeated issues like this point to a lack of professional communication.
Major institutions have strict standards for how they write.
The most dangerous request in this email
This email requests:
- Full name
- Address and location
- Phone number
- Age and occupation
- A copy of your passport or driver’s license
That is everything needed for identity theft. Once someone has those details, they can open accounts, target you with more scams or impersonate you.
The payment method adds false legitimacy
The email promises a bank-to-bank wire transfer. That detail adds a layer of realism. It also sets up the next step. Many scams later ask for “fees” to release the funds.
You send money, and the payment never arrives.
Even the spam excuse is part of the scam
At the end, the email tries to explain away the biggest red flag: “If you have received this message in your SPAM/BULK folder, it is simply because your ISP has introduced restrictions. We urge that you treat it as a matter of urgency.” That is not a reassurance. It is a warning sign.
Scammers know their messages look suspicious, so they try to explain it away before you question it.
THE ONE THING SCAMMERS CHECK BEFORE TARGETING YOU ONLINE

How to stay safe from scam emails
Scams like this follow a pattern, and once you know what to look for, you can shut them down quickly before any damage is done.
1) Ignore and delete the message
Do not reply or engage in any way. Even a quick response tells scammers your email is active, which can lead to more targeted attacks. The safest move is to delete it and move on.
2) Do not click links or download attachments
Scam emails often hide malicious links or infected files. One click can take you to a fake login page or install malware on your device. If you were not expecting the message, do not interact with anything inside it.
3) Use strong antivirus software
Strong antivirus software adds another layer of protection. It can flag suspicious emails, block dangerous websites and stop malicious downloads before they cause harm. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com
4) Never send personal documents
No legitimate organization will ask for your passport, driver’s license or other sensitive documents through an unsolicited email. Sending that information can open the door to identity theft and financial fraud.
5) Look closely at the sender
Do not rely on the display name alone. Check the full email address carefully for misspellings, random numbers or free domains like Gmail. Small details often reveal a fake.
6) Go directly to official sources
If the message seems important, verify it on your own. Type the organization’s website into your browser or use a trusted contact method. Do not use the links or contact details provided in the email.
7) Remove your personal data from the internet
Scammers often rely on publicly available information to make their messages feel convincing. Data removal services can reduce what is out there, making it harder for criminals to target you in the first place. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com
8) Turn on two-factor authentication
Add an extra layer of security to your accounts. With 2FA enabled, a stolen password alone is not enough for someone to get in. This simple step can stop many attacks before they start.
9) Monitor your financial accounts and credit
Check your bank statements and credit reports regularly. Look for unfamiliar charges, new accounts or changes you did not make. Catching fraud early can limit the damage.
10) Consider placing a credit freeze
If you think your personal information was exposed, a credit freeze can help protect you. It prevents new credit accounts from being opened in your name without your approval.
11) Add identity theft protection
Because this scam asks for your name, address, phone number, age, occupation and a copy of your passport or driver’s license, identity theft protection can help you spot trouble faster. A good service can monitor your credit files, alert you to new activity and help you recover if someone uses your information to open accounts or commit fraud in your name. See my tips and best picks on Best Identity Theft Protection at Cyberguy.com
12) Report the scam
Mark the email as phishing in your inbox. This helps your email provider block similar messages and protects other people from falling into the same trap.

Kurt’s key takeaways
This email tries hard to look official. It uses a real organization, a real name and a convincing story. Still, the cracks show up quickly once you slow down. A Gmail reply address, a massive payout, a vague greeting and a request for identity documents all point in the same direction. Scams like this rely on one thing: getting you to act before you think. Take a second look, and the whole thing falls apart.

Blue Origin explosion is a major setback for NASA’s Moon plans and Amazon’s Starlink competitor
While Blue Origin investigates the root cause behind last night’s spectacular explosion of its New Glenn rocket, it’s already clear that this will be a major setback for NASA’s Moon base plans and Amazon’s fledgling Leo space internet constellation.
The incident occurred at about 9pm at Blue Origin’s Florida launch site during a hot-fire test, where seven engines in the booster stage are lit while keeping the 322-foot-tall rocket fixed to the launchpad. The explosion and ensuing fireball severely damaged the only launchpad Blue Origin has for its New Glenn rocket.
“It’s too early to know the root cause but we’re already working to find it,” wrote Blue Origin boss Jeff Bezos on X. “Very rough day, but we’ll rebuild whatever needs rebuilding and get back to flying. It’s worth it.”
According to sources speaking to Ars Technica, the transporter-erector and one of the lightning towers at LC-36A may not be salvageable. “New Glenn almost certainly will not launch again in 2026, and frankly a launch during the first half of 2027 would be heroic given the launch site concerns,” writes Eric Berger, senior space editor at Ars Technica.
Such a delay would affect NASA’s Moon base plans. NASA announced on Tuesday that New Glenn would deliver a robotic lunar lander as soon as fall 2026. In 2027, Blue Origin is also scheduled to participate in the upcoming Artemis III mission, which will see astronauts docking their Orion capsule with lunar landers developed by SpaceX and Blue Origin.
“Spaceflight is unforgiving, and developing new heavy-lift launch capability is extraordinarily difficult,” said NASA administrator Jared Isaacman on X. “We will work with our partners to support a thorough investigation of this anomaly, assess near-term mission impacts, and get back to launching rockets.”
The New Glenn rocket that exploded Thursday night was being prepped to carry 48 Amazon Leo satellites — the largest batch ever slated for a single launch — into low-Earth orbit on an upcoming mission. The satellites were not onboard.
To date Amazon has launched just over 300 of the 1,618 Leo satellites the FCC requires by July 30, 2026. Amazon has applied for an extension to keep its license.
Amazon had been counting on New Glenn’s massive payload capacity and reusable boosters to accelerate a launch schedule that is already behind. Without its primary workhorse, Amazon will be forced to rely more heavily on secondary providers like United Launch Alliance (ULA) and Arianespace — and its chief rival, SpaceX.
“Sorry to see this,” wrote fellow billionaire spaceman Elon Musk on X. “I hope you recover quickly.”
