Russian state hackers are using a maximum-severity vulnerability in Microsoft Outlook’s Exchange Server to backdoor unpatched machines and steal credentials and other confidential information from them, security researchers said Thursday.

The attacks are coming from TA488, a tracking name for a group working on behalf of the Kremlin, Proofpoint researchers said Thursday. Proofpoint and the National Security Agency jointly warned last week that the group, also tracked as Laundry Bear and Void Blizzard, had been carrying out similar attacks by exploiting a zero-day vulnerability in an email service from Zimbra. The revelation that TA488 is also exploiting the Exchange Server vulnerability to install advanced malware when a user does nothing other than open an email sent to an Outlook Web Access (OWA) account has elevated the group’s profile and assessments of its abilities.

Doubling down

“TA488 is doubling down on the use of ‘half-click’ exploits—where opening the email is enough to trigger compromise—with significantly improved loading mechanisms, techniques, and malware, signaling an improvement in the group’s tradecraft and capability,” Proofpoint researchers wrote. “This novel infection chain ends with a previously unknown JavaScript browser-based implant we call OWAReaper, purpose-built for persistent access inside OWA.”

One of a series of striking AI-assisted math discoveries, this one feels a little different.

As millions of people were coming down from the excitement of the FIFA World Cup Final at the start of last week, a different kind of excitement was building within the mathematical community.

Levent Alpöge, a mathematician working at the artificial intelligence company Anthropic, made a very casual announcement on X that he had found a counterexample to the Jacobian conjecture, a very old and well-known problem in a field of mathematics called algebraic geometry. He had done this using Anthropic’s large language model Claude Fable 5, released to the general public only a few weeks ago.

This is just the latest of many striking mathematical breakthroughs made by mathematicians working with large language models. But this one feels a little different to those that have come before.

What Is the Jacobian Conjecture?

First, what is a conjecture? It’s an idea that some mathematicians believe is true but nobody has been able to prove or disprove.

Now to the Jacobian conjecture. It’s fairly abstract but not too difficult to describe.

The conjecture involves functions, which are like little machines which you put one or more numbers into and out pop other numbers according to some rule or equation. In this case, the functions use what are called polynomials.

Specifically, it’s about situations where the numbers represent points in a space, like coordinates on a map. So we can imagine that when the function takes in some numbers and puts out some other numbers, it is moving the points in space.

You can test how “nicely” a function moves everything around in space by calculating something called the Jacobian determinant. If the Jacobian determinant is always a constant number that is not zero, then the function never folds or crushes space around a particular point.

The Jacobian conjecture states that when the Jacobian determinant is a non-zero constant, there should always exist another function, also made up of polynomials, that reverses the original one. This will return all the points to their starting positions.

Not every function is reversible. For example, if our starting function moves two of the original points onto a single point, then we cannot reverse it. Once the points have been merged, we cannot distinguish between them to send them back to the right positions.

A Long History of Attempts—and Failures

The two-dimensional version of the Jacobian conjecture was stated by Czech mathematician Ludwig Kraus in 1884. It was generalized to any number of dimensions by German mathematician Ott-Heinrich Keller in 1939.

It was considered so compelling that Fields Medalist Stephen Smale included it in his 1998 list of Mathematical Problems for the Next Century.

During its long history, the Jacobian conjecture has been the subject of many claimed proofs, including by Beniamino Segre and Wolfgang Gröbner, two famed 20th-century mathematicians. However, in each case, subtle errors were found that invalidated the arguments.

Despite this, there have also been a number of valid efforts showing the conjecture is true with various restrictions. Computational results have also shown it is true in two dimensions for polynomials up to degree 100 (that is, including powers of the variables up to 100).

But nobody had proved the general case—or found an example showing the conjecture was wrong.

A Deceptively Simple Answer

One of the key reasons the Jacobian conjecture is so intriguing is that, in theory, it should be easy to find a counterexample. It is straightforward to come up with examples of functions that merge points, and also examples of polynomial mappings that have a constant Jacobian determinant.

However, finding a polynomial mapping with both properties is the challenge. Indeed, as one Math Stack Exchange user noted in a post from 2017, “for all what we know, some smart undergraduate can simply write a formula […] that will be a counter-example to this conjecture.”

Indeed, this did turn out to be the case for Alpöge’s function, which is short enough to fit into a single X post. He found an example of a function in three dimensions which has a constant Jacobian determinant of -2, and which moves multiple input points to the same output point, so it is not reversible.

It shows the conjecture is false for every dimension larger than 2, with the original conjecture in two dimensions remaining open. The brevity of the counterexample made it easy for other mathematicians to verify.

The Latest Advance in a Growing Series

Alpöge’s discovery is the latest in a string of high-profile mathematical breakthroughs made by large language models. Recent examples include OpenAI’s disproof of the unit distance conjecture, and the proof of Erdős’ problem 1196 by Liam Price, a 23-year-old amateur mathematician.

Both examples illustrate one of the most striking strengths of AI models. They can draw on ideas from different areas of mathematics, combining them in a novel way to prove astonishing results.

At the time of writing, details have not been made public regarding exactly how Alpöge prompted the AI model to produce the Jacobian conjecture counterexample and what its output looked like. However, so far this result appears to be of a different nature.

Unlike many other recent AI-assisted breakthroughs, the counterexample itself is remarkably simple. The difficulty in finding it seems to have lain not in an intricate construction or a lengthy proof, but rather in finding a good way of navigating an enormous search space of possible polynomial mappings to find one with the right properties.

This suggests AI may prove to be just as valuable for discovering unexpected mathematical objects as it is for constructing proofs. What this means for the future of mathematics—and human mathematicians—remains to be seen.

Apple may be moving faster than expected in its modem development work, and Qualcomm’s latest comments suggest that shift is already reshaping the iPhone supply chain. 

Qualcomm overnight said supply constraints are shrinking some of its Apple business faster than anticipated. “It’s availability of supply,” CEO Cristiano Amon told Reuters.

While he wasn’t specific, that likely reflects the broader industry shortage in memory, storage, and everything else and means the company’s share of components used for the next iPhone launch will fall “well below” its anticipated estimates. Amon says this is part of a transition in which future Qualcomm income will be generated by AI datacenter demand.

The company also intends to boost modem prices on Sept. 1 (And remember, the patent licensing agreement between Apple and Qualcomm expires in March 2027.)

Given Apple is selling plenty of smartphones (even as the broader industry shrinks), supply constraints won’t necessarily be because of demand for the devices; this could reflect Apple’s plan to divide the iPhone release schedule across several months, as well as its future modem development efforts. 

Reports for months have indicated Apple plans to introduce new iPhones twice a year, with the Pro range updated each fall and entry-level devices scheduled for spring. It’s a move that’s likely to help build more consistent quarterly earnings by spreading demand across different parts of the year and could reduce short-term demand for components.

Things look a little different this year, of course; the expected introduction of the new iPhone Ultra means Apple will be making three new iPhone models, not the customary four – though there is also speculation the Ultra may not ship in quantity until later on this year. 

How much does Apple need Qualcomm? Not much

There’s also Apple’s own modem development plans to consider. We know Apple’s relationship with Qualcomm isn’t easy. The two firms were engaged in costly litigation before they found a way to bury the hatchet and work together on 5G iPhones while Apple developed its C-series modems.

Those C-series modems are already used in Apple devices. The iPhone 16e, 17e and iPhone Air carry Apple’s C1/C1X modem, with the C2 variant expected in the 18 Pro series this year. 

Apple’s new modem is expected to deliver better battery efficiency, improved cellular network privacy, and AI-supported network efficiency. So, your device should last longer, be less visible to your carrier, and better able to get a connection — even when connectivity is constrained. 

Next year’s 18-series devices will certainly stick with Apple’s modems, meaning Qualcomm’s remaining Apple business should be wrapped up in the release this fall. As Apple’s modem appears in more devices, you’ll probably only see Qualcomm modems used to provide mmWave support, which realistically has very little traction or carrier support outside America.

Waiting to replace mmWave

That view is supported by reports based on information recently stolen from Apple’s India-based iPhone partner, Tata. It claimed Apple will use the C2 in internationally sold iPhones Pro and Max, while keeping to Qualcomm in US devices.

If Apple takes the same approach with next year’s iPhone releases, it would mean only US iPhones — and probably not all of them — have mmWave. As a result, Qualcomm’s modems will only be available in a very small subset of iPhones sold. That would almost certainly account for the modem maker’s reduced Apple optimism. (Apple is also part of the 6G standard development group, which implies it hopes to find some way to replace mmWave.)

It also indicates Apple is less likely to renew its current patent licensing deal, though it could still require some licenses since Qualcomm’s SEPs include some 5G-essential technologies. The other takeaway here: Apple has a high degree of confidence in its forthcoming C2 modem, which makes sense given how well-received its C1 modem has been. 

A clean sweep

One more thought. It is interesting the extent to which Tim Cook’s Apple seems to be finalizing much of its business before the transition to new CEO John Ternus on Sept. 1. (It is also notable that Qualcomm also intends to raise its prices on the same date.)

Note to privacy-conscious vandals: If you're going to destroy Flock license plate readers, make sure you also take out the other CCTV cameras in the area that could catch you in your crime. Otherwise, you'll end up like one unlucky Californian. Marcus Bee, 40, was arrested by the Monterey County Sheriff’s Office on Tuesday, accused of joining the ever-growing band of US citizens damaging the controversial cameras popping up across the country. A police report filed this week stated that Bee, of Pismo Beach, was arrested on suspicion of attacking at least three Flock cameras in Lockwood and Bradley. According to the deflock.org website, which maps Flock camera deployments, there are only three of the automated license plate readers (ALPRs) running in the two communities – one in Lockwood and two in Bradley, roughly 25 miles away. Police allege Bee caused thousands of dollars’ worth of damage to “public safety infrastructure.” Monterey County Sheriff’s Office added that Bee was caught after “his actions were captured by other surveillance cameras located nearby,” along with other investigative leads. "This arrest sends a clear message that anyone who intentionally damages public safety equipment will be identified, arrested, and held accountable," said Monterey County Sheriff Tina Nieto. "These cameras have become an invaluable investigative resource that helps us solve crimes, recover stolen vehicles and ag equipment, locate missing persons, and protect our communities. Any attempts to disable these systems will not prevent us from doing our job. “In this case, the suspect's own actions were captured on surveillance cameras, leading directly to his arrest. We will continue to aggressively investigate these crimes and seek prosecution against anyone who targets public safety infrastructure." Bee was jailed with bail set at $30,000. The case follows a similar one in Georgia last week, although local police were unable to identify the suspect(s) behind the two attacks, which involved setting two ALPRs on fire. The two attacks were timed fairly close together, although the phenomenon of inflicting criminal damage onto Flock cameras is something of a long-running trend. Several US police forces have been tasked with arresting alleged Flock vandals, including Jeffrey Scott Sovern, 41, who authorities believe was behind a spate of attacks on ALPR cameras in North Suffolk, Virginia, between April and October 2025. He said, at a hearing in June, that he believed the technology was unconstitutional. Flock cameras: A problem or simply misunderstood? The Monterey County Sheriff’s Office said Flock’s cameras “are an important investigative tool” used to help solve various types of crimes, including missing persons cases, car thefts, and violent crimes such as shootings and homicides where suspect vehicles are involved. Contrary to the opinions held by many, it went on to say, the cameras “are used exclusively to support legitimate criminal investigations,” not to support the US government’s anti-immigration efforts. Likewise, Flock has repeatedly denied offering contracts to agencies such as Immigration and Customs Enforcement (ICE), although reports suggest police were instead carrying out searches on ICE's behalf. Customs and Border Protection (CBP) has also allegedly used Flock data in its own immigration investigations. Other critiques of the technology used by thousands of police departments across the US include problematic abuses, such as police officers using it to stalk romantic interests. The Institute of Justice is aware of at least 26 cases of this behavior, it reported earlier this month, with the majority taking place since 2024. Additionally, the American Civil Liberties Union (ACLU) takes issue with the scale of data gathering by ALPRs. It claims that less than 1 percent of the cars scanned are connected to crime, yet they still have details added to a database, such as vehicle manufacturer, model, color, license plate number, bumper stickers, and scratches. Flock CEO Garrett Langley claimed this week in an interview with The Drive that the company’s cameras were used to solve around 1 million crimes across the US last year. Responding to claims such as Sovern’s – that the cameras are unconstitutional, specifically that they violate Americans’ Fourth Amendment rights – Langley said there are no legal issues, and he doesn’t foresee any arising in the future. Flock’s spokespeople have repeatedly condemned the cases of camera vandalism, highlighting the risk of losing evidence that could be crucial to solving ongoing criminal cases. ®
