Latest / Tech Talks With Kinsoft / Stake - A Breach at the Broker Behind the Broker, and the Closed Accounts Still on File
Transcript
- 0:00I want you to think about the last time you signed
- 0:02up for a financial product online. Right, which
- 0:05for most of us is pretty often these days. Yeah,
- 0:07exactly. Maybe it was a sleek new trading app,
- 0:10or a high -yield savings account, or one of those
- 0:13platforms for transferring currency overseas.
- 0:16You tap a few buttons, you check a box that says
- 0:19you agree to the terms and conditions, which
- 0:20no one reads, and you hand over your name, your
- 0:23home address, and your tax details. All in a
- 0:26matter of seconds. Right. And in your mind, you've
- 0:29established a relationship with exactly one company.
- 0:32But here is the million -dollar question. How
- 0:35many companies actually got that data? Well,
- 0:38I mean, it's an illusion, right? That one -to
- 0:40-one relationship? Yeah. When you hit submit,
- 0:43your personal information doesn't just sit in
- 0:45a single database. It gets fragmented. cascades
- 0:48across an entire ecosystem of third -party vendors,
- 0:52compliance checkers, infrastructure providers.
- 0:54And that hidden ecosystem is the exact focus
- 0:57of today's Deep Dive. We are analyzing a massive
- 1:00data breach involving a company that you have
- 1:03probably never even heard of. I'd be surprised
- 1:05as many people outside the industry have. Right.
- 1:08They are called DriveWealth, but... While their
- 1:10name might not ring a bell, they sit right behind
- 1:13some incredibly popular financial platforms.
- 1:15I'm talking about brands like Stake, Revolut,
- 1:18and Hatch. Some heavy hitters in the fintech
- 1:20space. Definitely. So we are going to explore
- 1:23what happens when the vendor behind the vendor
- 1:25gets compromised and what that actually means
- 1:28for your personal information. It's a fascinating
- 1:30chain reaction. It really is. To put this in
- 1:33perspective, imagine ordering delivery from your
- 1:36absolute favorite local restaurant. You love
- 1:39their branding. You trust their quality. You've
- 1:41been eating there for years. Yeah. You know what
- 1:43you're getting. Exactly. But you are completely
- 1:46unaware that, like, a year ago, they quietly
- 1:48outsourced all their food prep to a massive ghost
- 1:51kitchen all the way across town. Right. You place
- 1:53your order on the restaurant's slick app, but
- 1:56the ghost kitchen is actually the one handling
- 1:58your food. Handling the actual raw ingredients,
- 2:00yeah. Then you wake up and read the news that
- 2:02the ghost kitchen just got robbed. You didn't
- 2:04even know they existed. But because they had
- 2:07your order details and your address, suddenly
- 2:09you are very much involved in the fallout. That's
- 2:12a great way to look at it. The modern financial
- 2:14product is really just a stack of companies and
- 2:17your data flows down through all of them. So
- 2:20we really need to understand how these companies
- 2:22are structurally connected before we can make
- 2:25sense of how this breach unfolded. Let's look
- 2:27at Stake as our primary example here. Sure. Stake
- 2:30is a massively popular Sydney -based online investing
- 2:33platform. They have around half a million customers
- 2:36worldwide, and they built their whole brand on
- 2:38letting Australians easily buy U .S. shares right
- 2:41from their phones. Right. They made it very accessible.
- 2:43Yeah. The interface is beautiful. It feels totally
- 2:46seamless. But Stake isn't actually a registered
- 2:48U .S. broker. No, far from it. I mean, becoming
- 2:51a registered broker dealer in the United States
- 2:53involves a staggering amount of regulatory compliance.
- 2:56Like mountains of paperwork. Mountains, massive
- 2:58capital requirements, highly complex infrastructure.
- 3:01For a fintech startup in Sydney, building a Wall
- 3:04Street clearinghouse from scratch simply doesn't
- 3:06make sense. So what do they do instead? So they
- 3:09utilize what we call a brokerage as a service
- 3:12model. They partner with a New York -based broker
- 3:14dealer called DriveWealth. DriveWealth is the
- 3:17plumbing hidden behind the drywall. The plumbing.
- 3:19Yeah. They execute the trades. They hold the
- 3:22assets and they actually clear the transactions
- 3:24on the American side. The broker behind the broker.
- 3:27So when you open that stake account in Australia
- 3:29or, you know, a hatch account in New Zealand,
- 3:32your details are actively flowing down the API
- 3:35chain to drive wealth so they can legally open
- 3:38your account in New York. Exactly. Which brings
- 3:41us to the timeline of the incident. And this
- 3:44is where things get a bit messy. According to
- 3:47the public notices. Unknown attackers breached
- 3:50DriveWell's network on Friday, September 4th
- 3:52and Saturday, September 5th, 2026. Right. A weekend
- 3:56attack. Very common. DriveWell's internal security
- 3:59teams managed to contain the compromise by that
- 4:02Saturday. But Stake didn't publish an incident
- 4:05page until Monday, September 21st. Hatch told
- 4:08its customers on the 22nd. Revolut emailed people
- 4:12on the 24th. And Stake's direct emails to their
- 4:15customers didn't go out until Friday the 25th.
- 4:18That is a significant delay. It's a near three
- 4:20week gap. Why does it take so long to tell a
- 4:24user their data is gone? Well, it highlights
- 4:27the agonizingly complex chain of communication
- 4:29in business to business breaches. When containment
- 4:33happens on the 5th, the real work is actually
- 4:35just starting. Really? Oh, absolutely. The primary
- 4:39vendor, DriveWealth in this case, has to bring
- 4:42in external forensic teams to analyze server
- 4:44logs. They have to determine the actual blast
- 4:47radius of the attack. To see what got hit. Yes.
- 4:50They have to figure out exactly which files were
- 4:52accessed. And once they map that out, they realize
- 4:55they have compromised data belonging to dozens
- 4:58of different corporate partners globally. Wow.
- 5:01So they can't just send out a mass email. Not
- 5:03at all. They have to notify the legal teams at
- 5:05stake at Revolut. And then what? Those companies
- 5:09have to figure it out on their end. Exactly.
- 5:11Then those secondary companies have to conduct
- 5:13their own internal audits. They have to coordinate
- 5:15with regulators in their respective jurisdictions
- 5:18like Australia, the UK, New Zealand, and carefully
- 5:21draft public communications that won't trigger
- 5:23a massive panic. So the communication lag isn't
- 5:27necessarily a cover -up? No, it's mostly a byproduct
- 5:30of a deeply entangled supply chain trying to
- 5:32untangle a forensic mess. Okay, let's unpack
- 5:35this because the nature of the breach itself
- 5:37is what I find most confusing. How so? Well,
- 5:40Tribewell's notice to the California Attorney
- 5:42General described it as a sophisticated social
- 5:45engineering campaign. Right. The reports explicitly
- 5:48state there was no CVE, meaning the hackers didn't
- 5:52exploit some undocumented software flaw or zero
- 5:55-day vulnerability in the code. No technical
- 5:57exploit, yeah. And no criminal ransomware group
- 6:00has stepped up to claim the attack on the dark
- 6:02web. I'm having trouble picturing this. Are we
- 6:05talking about a simple phishing email? Or does
- 6:07this just mean someone with high -level access
- 6:10got sweet -talked on the phone into handing over
- 6:12the keys? The term sweet -talked dramatically
- 6:15understates the psychological manipulation involved
- 6:17in modern social engineering. Really? Oh, it's
- 6:20that intense. Oof. Attackers aren't just sending
- 6:23poorly spelled emails from foreign princes anymore.
- 6:25They are exploiting the fact that the weakest
- 6:27link in any enterprise security architecture
- 6:30isn't the firewall. It's the people. It's the
- 6:33human being managing it. Walk me through how
- 6:36that actually works, because if a financial institution
- 6:38has two -factor authentication, VPNs, and zero
- 6:42-trust security models, how does a phone call
- 6:44bypass all of that? Okay, so attackers will meticulously
- 6:49research an organization's hierarchy using platforms
- 6:52like LinkedIn. Oh, wow. They look for new hires
- 6:55in the IT or HR departments, people who are still
- 6:58trying to be helpful and might not know all the
- 7:01internal protocols yet. So they target the new
- 7:03guy. Exactly. The attacker will spoof an internal
- 7:05phone number so the caller ID looks completely
- 7:08legitimate. They'll call that employee late on
- 7:10a Friday afternoon, perhaps posing as a senior
- 7:13executive who is locked out of their account.
- 7:15Oh, man. And they say they urgently need to execute
- 7:17a critical task before the weekend. So they manufacture
- 7:20a crisis. They manufacture urgency and they leverage
- 7:23corporate authority. Or conversely, the attacker
- 7:26poses as the IT help desk calling the employee.
- 7:29Saying something's wrong with their computer.
- 7:30Yes, claiming there is suspicious activity on
- 7:32the employee's workstation and insisting they
- 7:35need the employee to read back a one -time passcode
- 7:37to secure the system. And people fall for that.
- 7:40They do. Once the employee hands over that code,
- 7:42the attacker defeats the two -factor authentication
- 7:44and just walks right through the front door.
- 7:47That is wild. They didn't hack the software.
- 7:49They hacked the human's natural inclination to
- 7:51trust authority and resolve a crisis. That is
- 7:54terrifying. Mostly because it's so incredibly
- 7:57difficult to defend against. And it naturally
- 7:59leads to the next big question. Once these attackers
- 8:02bypassed the human element and got inside Tribe
- 8:05Wealth's environment, what did they actually
- 8:08get? Right, the data itself. Yeah. The list of
- 8:12what was stolen is highly specific. For state
- 8:14customers, the attackers took names, email addresses,
- 8:17phone numbers, and postal addresses. Standard
- 8:20PII, yeah. Right. But they also took the W -8
- 8:23or W -9 tax status, which is that required IRS
- 8:26paperwork for foreign investors. They got the
- 8:29DriveWealth account numbers, which correlate
- 8:31directly to the Stake Wall Street account numbers.
- 8:33And perhaps most concerning, they got portfolio
- 8:35snapshots. Meaning they saw the aggregate portfolio
- 8:39value, the cash balance, and the purchasing power
- 8:42at that exact moment in time. So they know exactly
- 8:45how much money a specific user has in play. Exactly.
- 8:49Now, Stake was very clear about what was not
- 8:52taken. The attackers did not get Stake logins
- 8:55or passwords. They didn't get bank account routing
- 8:58details, government ID numbers, or full trading
- 9:00histories. That's a crucial distinction. Yeah.
- 9:03And there have been no unauthorized trades, transfers,
- 9:06or withdrawals reported. Stake also heavily emphasized
- 9:09that their own systems, their primary app, and
- 9:11their internal website were completely unaffected.
- 9:14The incident was entirely contained within DriveWealth's
- 9:17environment. Which is a technically accurate
- 9:19defense, but frankly, it offers very little comfort
- 9:22to the end user. Not at all. Stakes perimeter
- 9:24security could be flawless, but to make the product
- 9:27function, the data still had to leave their fortress.
- 9:30It reminds me of a burglar breaking into your
- 9:32house. You've got this incredibly secure safe
- 9:35in the wall, and the burglar doesn't even try
- 9:37to crack it. Right. They ignore the jewelry.
- 9:39They leave the expensive TV on the wall. Instead,
- 9:41they just walk into your home office, open a
- 9:43filing cabinet, and steal your bank statements
- 9:45and your personal address book. They aren't trying
- 9:47to rob you today. No, they are gathering the
- 9:50intelligence required to run a highly personalized
- 9:52long con on you tomorrow. If we connect this
- 9:55to the bigger picture, you have perfectly described
- 9:57why this specific data haul is so alarming. Because
- 10:01of what they can do with it later. Exactly. In
- 10:04cybersecurity circles, this particular combination
- 10:06of stolen data, contact info, administrative
- 10:09tax details, and exact financial balances is
- 10:12referred to as a scammer's starter kit. A scammer's
- 10:15starter kit. Because it allows them to manufacture
- 10:19an incredibly convincing illusion of legitimacy.
- 10:21Right. Think about how a typical scam call operates.
- 10:25Usually it's a numbers game. They call thousands
- 10:27of people with a generic script hoping someone
- 10:30bites. Right. The whole your car warranty has
- 10:32expired routine. Exactly. But with this data,
- 10:35the attack is spear phishing. Imagine your phone
- 10:39rings. The caller ID is spoofed to read stake
- 10:42fraud prevention. The person on the line is calm,
- 10:45professional, and speaks with total authority.
- 10:47Okay. They know your full name and your home
- 10:50address. They casually mention your W -8 tax
- 10:53status, which immediately implies they have deep
- 10:55administrative access to your account. Yeah,
- 10:58that would definitely catch me off guard. And
- 11:00then the psychological kicker. They quote your
- 11:03exact portfolio value and cash balance down to
- 11:06the cent. If someone calls me and knows exactly
- 11:09how much uninvested cash is sitting in my brokerage
- 11:11account, My brain is hardwired to assume they
- 11:14must be an official representative. Like, how
- 11:17else could they possibly know that? You fall
- 11:19into the trap of established trust. And once
- 11:22they have you believing they are legitimate,
- 11:23they introduce the threat. Ah. They tell you
- 11:27your account has been compromised by hackers,
- 11:29which is a brutal irony, and that you need to
- 11:32take immediate action to protect your assets.
- 11:34Right, they create that panic again. They might
- 11:36instruct you to transfer your funds to a quote
- 11:39-unquote safe holding account they control. Or
- 11:42they might ask you to verify a security code
- 11:43they just texted you. But that text message is
- 11:46actually them trying to trigger a password reset
- 11:48on your real account. Precisely. And they just
- 11:51need you to read the code out loud so they can
- 11:52finalize the takeover. Which is why Stake's specific
- 11:56warning to their customers following this breach
- 11:58is just... So vital. We have to relay this directly
- 12:00to you listening right now. It's the most important
- 12:03takeaway. Stake explicitly stated, quote, we
- 12:06will never ask for your password, PIN, or one
- 12:09-time codes. And we will never ask you to move
- 12:11your money to keep it safe, unquote. Furthermore,
- 12:15they are strongly advocating for users to switch
- 12:18to an authenticator app for two -factor authentication.
- 12:21rather than relying on SMS text messages. Which
- 12:24is fantastic advice. SMS is incredibly vulnerable
- 12:27to interception or SIM swapping attacks. An authenticator
- 12:31app generates the codes locally on your device,
- 12:33making it significantly harder for a remote social
- 12:35engineer to compromise. When a company's data
- 12:38leaks, telling the customer exactly what a fake
- 12:40phone call will sound like is the absolute best
- 12:43piece of practical mitigation they can offer.
- 12:45So here's where it gets really interesting. And
- 12:48honestly, for a lot of people, deeply infuriating.
- 12:51Oh, I know where you're going with this. The
- 12:53scariest part of this breach isn't just the specific
- 12:55data that was taken. It's whose data was taken.
- 12:59Stake admitted in their incident report that
- 13:01DriveWealth is required by law to retain customer
- 13:04records for an extended period. Yes. This means
- 13:07that even if a user's account was entirely inactive,
- 13:10their information was still caught up in the
- 13:12breach database. The persistence of historic
- 13:15data is a massive issue. Revolut actually faced
- 13:18a very similar situation in this same breach.
- 13:20Really? Yeah. They stated publicly that they
- 13:23had actually stopped sending Australian customer
- 13:25data to DriveWealth by the middle of last year
- 13:28as they transitioned away from that specific
- 13:30vendor relationship. But the historic records
- 13:33were still sitting on DriveWealth servers. Exactly.
- 13:35Wait, so I can try out a new fintech app, decide
- 13:40the interface isn't for me, delete the app from
- 13:42my phone. formally request to close my account,
- 13:46and my personal data is still legally trapped
- 13:48in a database on another continent that I didn't
- 13:51even know existed in the first place? That is
- 13:54the reality, yes. How is that justifiable? Well,
- 13:57this raises an important question, and it highlights
- 14:00a massive unresolved clash between two entirely
- 14:03different regulatory frameworks. Okay. On one
- 14:06side, you have strict financial record -keeping
- 14:08laws, anti -money laundering regulations, and
- 14:11counterterrorism financing laws. frequently referred
- 14:13to as AML and CTF, require financial institutions
- 14:17to hold on to customer records for years. For
- 14:20how long? Sometimes up to seven years after an
- 14:22account is formally closed. Wow. Why do they
- 14:25need it for that long? Because financial crimes
- 14:27aren't always discovered immediately. If investigators
- 14:30uncover an international money laundering syndicate,
- 14:33they need to trace the layered transactions back
- 14:35through time. Right. That makes sense. DriveWealth,
- 14:38as a regulated entity, has... Absolutely no choice
- 14:40but to comply with those retention laws. If they
- 14:43delete the data, they face massive federal fines.
- 14:46But on the other side of the ring, you have privacy
- 14:49and data minimization principles. Exactly. The
- 14:52golden rule of data privacy is that every record
- 14:55you keep past its active functional purpose is
- 14:59a record you will eventually lose. It's just
- 15:01a matter of time. The Office of the Australian
- 15:03Information Commissioner the OAIC is aggressively
- 15:06policing this tension right now. For context
- 15:09they recently launched an investigation into
- 15:11Latitude Financial following their massive data
- 15:14breach. Oh I remember that one. They are specifically
- 15:16focusing on whether that company took reasonable
- 15:19steps to destroy or de -identify personal information
- 15:22that was no longer actively required for business
- 15:24purposes. It just feels like an impossible paradox
- 15:27for these companies. Like the anti -money laundering
- 15:29laws demand that they stockpile the data to prevent
- 15:32financial crime. But stockpiling that data creates
- 15:35a massive, irresistible honeypot for cyber criminals
- 15:38to exploit. It is a systemic vulnerability built
- 15:41directly into the fabric of modern finance. And
- 15:43it fundamentally changes how consumers need to
- 15:46think about their digital footprint. In what
- 15:47way? You aren't just trusting a brand with your
- 15:50data for the duration of your usage. You are
- 15:52implicitly trusting them and their entire web
- 15:55of unseen vendors for as long as the law mandates
- 15:58the data must exist. Which transitions us perfectly
- 16:01into the broader business implications of all
- 16:03this. The supply chain domino effect. It's a
- 16:06huge problem. We mentioned earlier that one single
- 16:09incident at one shared provider ended up hitting
- 16:11three major brands across three different countries.
- 16:14Stake in Australia, Revolut globally, and Hatch
- 16:18in New Zealand. None of those three consumer
- 16:20-facing brands were attacked directly. But all
- 16:22of them had to wake up, manage the fallout, brief
- 16:25their national regulators, and deal with furious
- 16:28customers. It is the harsh reality of the modern
- 16:31vendor ecosystem. I mean, the phrase supply chain
- 16:34risk. Sounds incredibly dry and academic until
- 16:37your company is the one dealing with the brand
- 16:39damage. Seriously. And what is truly alarming
- 16:43is how poorly prepared most standard business
- 16:45contracts are for this exact scenario. Are you
- 16:48referencing the recent Queensland audit office
- 16:50report? Yes. The QAO published a fascinating
- 16:53audit on third party cyber risk. They reviewed
- 16:5636 different third party vendor contracts used
- 16:59by government and corporate entities. OK. Out
- 17:02of those 36. How many do you think actually required
- 17:05the third -party vendor to legally report their
- 17:08cybersecurity incidents and vulnerabilities back
- 17:11to the primary company? The number is staggeringly
- 17:13low. Out of 36 contracts, it was two. Two? Two
- 17:18contracts actually forced the vendor to pick
- 17:20up the phone and say, hey, we got hacked. Your
- 17:22customer's data might be compromised. It's a
- 17:24massive contractual blind spot. Companies are
- 17:27rushing to outsource their core operations to...
- 17:30payroll providers, practice management systems,
- 17:32CRM platforms, because it's cheaper and faster.
- 17:35Of course. But they aren't writing in the rigorous
- 17:37legal clauses that guarantee they will be notified
- 17:40when things go wrong at those providers. The
- 17:43vendors often dictate the boilerplate terms of
- 17:45service, and the primary companies just accept
- 17:47the risk. So what does this all mean for the
- 17:50company whose logo is actually glowing on your
- 17:52phone screen? Let's say you hire a general contractor
- 17:55to come and completely redo the roof of your
- 17:58house. Okay. That general contractor realizes
- 18:00they are overbooked, so they secretly hire a
- 18:03terrible, unqualified subcontractor to do the
- 18:06actual labor. The subcontractor is up on your
- 18:08roof, slips and drops a heavy hammer straight
- 18:10through your neighbor's incredibly expensive
- 18:12stained glass window. Ouch. Well, the neighbor
- 18:15doesn't care that a subcontractor dropped the
- 18:17hammer. Right. They don't even know who the subcontractor
- 18:19is. Exactly. The neighbor is going to march across
- 18:22the lawn and yell at you. You hired the general
- 18:24contractor. It was your roof. You are the face
- 18:27of the disaster. And in the eyes of privacy law,
- 18:30that is exactly how data breaches work. To their
- 18:33credit, Stake did the right thing here. They
- 18:34didn't just sit back and wait for DriveWealth
- 18:37to deal with the Australian regulators. No, they
- 18:39didn't. Stake proactively notified the OAIC themselves.
- 18:43Under Australia's notifiable data breaches scheme,
- 18:46if your organization is covered by the Privacy
- 18:48Act and personal information you are responsible
- 18:51for is exposed, you have an obligation to assess
- 18:54the harm and report it within a strict 30 -day
- 18:57window. Even if the actual exposure happened
- 18:59on a server in New York that you don't own. Stating
- 19:02it happened at our vendor is necessary context
- 19:05for the regulatory notification, but it is absolutely
- 19:08not an exemption from it. Right. You can't just
- 19:11pass the buck. The legal obligation, the potential
- 19:14regulatory fines, and most importantly, the severe
- 19:17reputational damage stays securely anchored to
- 19:20the front -facing brand. The customer placed
- 19:22their trust in stake, not drive wealth. Therefore,
- 19:25stake has to own the communication and the cleanup.
- 19:27And as we've discussed, they did step up and
- 19:30own it. They were highly transparent in their
- 19:32incident reporting about what was taken, what
- 19:34wasn't, and the mechanics of how it happened.
- 19:37They handled it well, given the circumstances.
- 19:39But zooming out, this entire situation really
- 19:42peels back the curtain on how modern digital
- 19:44services actually function. When you use a financial
- 19:47app today, your data is embarking on a journey
- 19:50down a deep, hidden stack of interconnected vendors,

- 20:24our ghost data for years after we leave their
- 20:27platforms, is the concept of deleting your account
- 20:30actually a complete illusion? Who really owns
- 20:33your digital footprint if you can never truly
- 20:35erase it? That is a deeply unsettling thought
