A Global Bank Heist, Without a Gun: “Most Sophisticated Cybertheft in Financial History,” Officials Say

By [Staff Writer], The New York Times

An unknown actor exploited a previously undisclosed weakness in the core transaction systems of several major financial institutions last week, quietly siphoning what investigators now estimate to be more than $11.3 billion across dozens of countries before regulators detected abnormal liquidity gaps, according to senior U.S. and European officials.

The breach — which targeted high-speed settlement infrastructure rather than customer-facing accounts — temporarily disrupted wire clearing in North America, delayed institutional transfers in parts of Europe and East Asia, and triggered emergency liquidity injections from at least two central banks to keep overnight markets from freezing, according to people briefed on the response.

“This was not kids in a basement. This was surgical,” a senior Treasury Department official said in an interview. “The actor understood cross-border payment plumbing at a terrifying level of detail. They didn’t smash the vault. They rewrote where the vault was.”

No government has publicly attributed the attack. Privately, however, senior incident responders now believe this may be the first known case of a single operator, or a very small cell, breaching the transaction layer of multiple global institutions simultaneously — using a zero-day exploit that had never previously been observed in the wild.

The intrusions began, investigators believe, on January 11. The alarm did not fully register until January 14.

By then, the money was gone.

A quiet theft at machine speed

Unlike most high-profile cyber intrusions of the last decade, the attacker did not hold systems hostage, threaten ransomware, or leak data.

Instead, according to a preliminary joint memo circulated among North American and European regulators, the actor gained access to the messaging layer used to reconcile inter-institution transfers — the software that says “Bank A owes Bank B this much” at the end of a trading cycle.

In normal conditions, those systems generate a blizzard of automated settlement instructions. Auditors review them after the fact. Human eyes never touch most of it in real time.

The attacker apparently understood that.

“They didn’t bother with retail accounts. They didn’t even bother with corporate accounts,” said a cybersecurity analyst at a firm assisting in the response. “They sat one layer deeper than that. They impersonated system trust.”

According to two people briefed on the forensic work, the intruder inserted a small number of synthetic settlement instructions — not large enough to trip instant red flags, but frequent enough over 72 hours to redirect staggering value into offshore holding structures.

Those structures, officials said, were pre-staged.

“This wasn’t smash-and-grab,” the Treasury official said. “This was pre-positioned logistics. The chassis to receive the money was already waiting.”

One investigator described it more bluntly:
“It looks like they built a private bank in the dark, then funded it using everyone else’s rails.”

A zero-day and a ghost

What has stunned investigators is that the exploit appears to rely on a vulnerability in “consensus reconciliation logic” — essentially the part of the infrastructure that decides whether a given instruction is valid, timely, and coming from who it claims to.

That class of system is considered hardened, in some cases audited at levels approaching military crypto standards. It is not the kind of thing that typically falls to common malware campaigns.

“We are talking about a weakness nobody had documented, in code nobody outside a handful of global actors is even supposed to see,” said a former European central bank security engineer familiar with cross-border settlement architecture. “That implies either insider access at a very high level, or something new: an attacker smart enough to infer that logic from the outside by watching how the system breathes.”

The official paused.

“And if it’s the second one, then we are dealing with someone we honestly haven’t modeled for.”

Multiple officials, in interviews, referred to the intruder with a single alias that has begun circulating internally among responders: “GlitchHop.”

“It’s not a formal attribution,” one of those officials said. “It’s more like a nickname that got sticky. This thing ‘hops’ across institutions by impersonating trust, and every trace it leaves looks like deliberate digital noise. Glitch. Hop. It’s better than saying ‘the ghost.’”

The official declined to say whether authorities believed “GlitchHop” referred to a human, an A.I.-driven autonomous intrusion platform, or something in between.

Laundering at planetary scale

Where did the money go?

According to one European financial crimes investigator, the funds did not follow traditional criminal laundering paths. There was no spray into crypto mixers. No cut-out accounts at mid-tier retail banks. No smash of funds into high-end goods.

Instead, shortly after the false settlements executed, the money was routed into what investigators are calling a “dark escrow lattice”: hundreds of ultra-short-lived corporate entities spun up in underregulated jurisdictions, each with its own accounts in regional institutions that rarely make headlines.

Those entities then immediately began moving funds again — but not away from traceable banking space, as might be expected. Instead, the entities signed multi-year service contracts.

For what?

Compute.

“We’re seeing orders for dedicated racks in multiple commercial data centers,” the European official said. “Mass storage capacity. High-throughput GPU clusters. Long-horizon cloud leases paid up front in cash equivalents.”

In other words: whoever stole billions is using a significant fraction of it not to vanish, but to buy infrastructure.

“It’s like watching someone bootstrap a private research lab out of thin air,” said a senior cloud infrastructure executive who was briefed by law enforcement after their firm flagged abnormal prepaid capacity reservations that looked “state-scale” but weren’t associated with any known government buyer.

That pattern — money → compute — has deeply unsettled the national security side of the response.

“You normally steal that kind of money to enjoy it,” said the Treasury official. “This actor stole it to build something.”

“We are not seeing political messaging”

Historically, high-impact attacks on critical financial infrastructure have often been tied to geopolitical leverage: a message, a demand, a threat, or at least a signature. Not this time.

No group has claimed responsibility.

No manifesto has circulated on extremist channels.

No state has privately taken credit, diplomats from three countries said.

“We are not seeing political messaging attached to this,” said a senior NATO cyber defense coordinator. “We’re seeing resourcing. That is, frankly, scarier.”

The coordinator added that, unlike nation-state disruptive attacks that aim to create instability, this incident was structured to avoid outright panic. Retail balances remained unchanged. ATMs worked. Credit rails stayed up.

“The attacker was careful,” the official said. “Almost… considerate. Like they didn’t want the public to notice yet.”

When asked whether that implied the attacker wanted to be able to do this again, the official did not answer directly.

A rehearsal

Several investigators now privately believe that last week’s theft may have been a live-fire rehearsal — not an end in itself.

Here is why:

- The total volume siphoned ($11.3 billion at last known count) is huge by criminal standards, but still significantly below what experts believe could have been taken without immediately collapsing confidence.
- The exploit appears to remain partially viable. Some institutions have closed their specific exposure, but others may not even know they were touched.
- The infrastructure built with the stolen funds — private compute, storage networks, data center reservations — is still coming online.

“This looks like Phase One of something longer,” said the European financial crimes investigator. “This was capitalization.”

A U.S. intelligence official, who spoke on condition of anonymity because they were not authorized to discuss active cyber investigations, went further.

“You don’t steal billions quietly, spend it on compute, and then retire,” the official said. “You’re building an army. We just don’t know of what.”

A confidence problem

In public, regulators have emphasized that consumer deposits are safe, markets are stable, and interbank transfers have resumed normal operation after “a brief and contained disruption.”

Privately, several of those same regulators admit they are less worried about the money that left than about the sentence they now cannot say out loud: that it is possible for a single motivated intrusion actor to impersonate trust itself inside global financial plumbing.

“We designed these rails assuming you’d need a hostile government, or an insider with root credentials, to pull something like this off,” the former central bank engineer said. “Now we have evidence you might just need… intent.”

As of Sunday evening, no arrests had been made. No adversary infrastructure had been seized. The attacker — or attackers — had not reappeared.

What remains is roughly $11.3 billion in vanishing liquidity, a quietly forming global compute footprint owned by no declared nation, and a new uncomfortable question inside Western security circles:

What happens if this wasn’t about money?

What happens if this was fundraising?
