In mid-September 2025, we detected suspicious activity that later investigation determined to be a highly sophisticated espionage campaign. The attackers used AI’s “agentic” capabilities to an unprecedented degree­—using AI not just as an advisor, but to execute the cyberattacks themselves.

The threat actor—­whom we assess with high confidence was a Chinese state-sponsored group—­manipulated our Claude Code tool into attempting infiltration into roughly thirty global targets and succeeded in a small number of cases. The operation targeted large tech companies, financial institutions, chemical manufacturing companies, and government agencies. We believe this is the first documented case of a large-scale cyberattack executed without substantial human intervention...

From an article:

According to court documents, Chapman hosted the North Korean IT workers’ computers in her own home between October 2020 and October 2023, creating a so-called “laptop farm” which was used to make it appear as though the devices were located in the United States.

The North Koreans were hired as remote software and application developers with multiple Fortune 500 companies, including an aerospace and defense company, a major television network, a Silicon Valley technology company, and a high-profile company...

The US Department of Justice on Wednesday announced the indictment of 12 Chinese individuals accused of more than a decade of hacker intrusions around the world, including eight staffers for the contractor i-Soon, two officials at China’s Ministry of Public Security who allegedly worked with them, and two other alleged hackers who are said to be part of the Chinese hacker group APT27, or Silk Typhoon, which prosecutors say was involved in the US Treasury breach late last year.

[…]

According to prosecutors, the group as a whole has targeted US state and federal agencies, foreign ministries of countries across Asia, Chinese dissidents, US-based media outlets that have criticized the Chinese government, and most recently the US Treasury, which was breached between September and December of last year. An internal Treasury report ...

Legal documents released in ongoing US litigation between NSO Group and WhatsApp have revealed for the first time that the Israeli cyberweapons maker ­ and not its government customers ­ is the party that “installs and extracts” information from mobile phones targeted by the company’s hacking software...

The Biden administration on Thursday said it’s banning the company from selling its products to new US-based customers starting on July 20, with the company only allowed to provide software updates to existing customers through September 29. The ban—­the first such action under authorities given to the Commerce Department in 2019­—follows years of warnings from the US intelligence community about Kaspersky being a national security threat because Moscow could allegedly commandeer its all-seeing antivirus software to spy on its customers...

The basic plan was to develop coded messages from recordings of whales, dolphins, sea lions, and seals. The submarine would broadcast the noises and a computer—the Combo Signal Recognizer (CSR)—would detect the specific patterns and decode them on the other end. In theory, this idea was relatively simple. As work progressed, the Navy found a number of complicated problems to overcome, the bulk of which centered on the authenticity of the code itself.

The message structure couldn’t just substitute the moaning of a whale or a crying seal for As and Bs or even whole words. In addition, the sounds Navy technicians recorded between 1959 and 1965 all had natural background noise. With the technology available, it would have been hard to scrub that out. Repeated blasts of the same sounds with identical extra noise would stand out to even untrained sonar operators...

From their report:

In collaboration with OpenAI, we are sharing threat intelligence showing detected state affiliated adversaries—tracked as Forest Blizzard, Emerald Sleet, Crimson Sandstorm, Charcoal Typhoon, and Salmon Typhoon—using LLMs to augment cyberoperations.

The only way Microsoft or OpenAI would know this would be to spy on chatbot sessions. I’m sure the terms of service—if I bothered to read them—gives them that permission. And of course it’s no surprise that Microsoft and OpenAI (and, presumably, everyone else) are spying on our usage of AI, but this confirms it...

Before the internet, putting someone under surveillance was expensive and time-consuming. You had to manually follow someone around, noting where they went, whom they talked to, what they purchased, what they did, and what they read. That world is forever gone. Our phones track our locations. Credit cards track our purchases. Apps track whom we talk to, and e-readers know what we read. Computers collect data about what we’re doing on them, and as both storage and processing have become cheaper, that data is increasingly saved and used. What was manual and individual has become bulk and mass. Surveillance has ...

An app with the name Signal Plus Messenger was available on Play for nine months and had been downloaded from Play roughly 100 times before Google took it down last April after being tipped off by security firm ESET. It was also available in the Samsung app store and on signalplus[.]org, a dedicated website mimicking the official Signal.org. An app calling itself FlyGram, meanwhile, was created by the same threat actor and was available through the same three channels. Google removed it from Play in 2021. Both apps remain available in the Samsung store...

The hackers had deep, persistent access and appeared to be after anything they could get their hands on—plans, capabilities, assessments of military shortcomings, according to three former senior U.S. officials, who were among a dozen current and former U.S. and Japanese officials interviewed, who spoke on the condition of anonymity because of the matter’s sensitivity.

The 2020 penetration was so disturbing that Gen. Paul Nakasone, the head of the NSA and U.S. Cyber Command, and Matthew Pottinger, who was White House deputy national security adviser at the time, raced to Tokyo. They briefed the defense minister, who was so concerned that he arranged for them to alert the prime minister himself...

The reports on Guterres appear to contain the secretary general’s personal conversations with aides regarding diplomatic encounters. They indicate that the United States relied on spying powers granted under the Foreign Intelligence Surveillance Act (FISA) to gather the intercepts.

Lots of details about different conversations in the article, which are based on classified documents leaked on Discord by Jack Teixeira.

There will probably a lot of faux outrage at this, but spying on foreign leaders is a perfectly legitimate use of the NSA’s capabilities and authorities. (If the NSA didn’t spy on the UN Secretary General, we should fire it and replace it with a more competent NSA.) It’s the bulk surveillance of whole populations that should outrage us...

The headline says that the FBI “sabotaged” the malware, which seems to be wrong.

Presumably we will learn more soon.

EDITED TO ADD: New York Times story.

EDITED TO ADD: Maybe “sabotaged” is the right word. The FBI hacked the malware so that it disabled itself.

Despite the bravado of its developers, Snake is among the most sophisticated pieces of malware ever found, the FBI said. The modular design, custom encryption layers, and high-caliber quality of the code base have made it hard if not impossible for antivirus software to detect. As FBI agents continued to monitor Snake, however, they slowly uncovered some surprising weaknesses. For one, there was a critical cryptographic key with a prime length of just 128 bits, making it vulnerable to factoring attacks that expose the secret key. This weak key was used in Diffie-Hellman key exchanges that allowed each infected machine to have a unique key when communicating with another machine...

Thousands of pages of secret documents reveal how Vulkan’s engineers have worked for Russian military and intelligence agencies to support hacking operations, train operatives before attacks on national infrastructure, spread disinformation and control sections of the internet.

The company’s work is linked to the federal security service or FSB, the domestic spy agency; the operational and intelligence divisions of the armed forces, known as the GOU and GRU; and the SVR, Russia’s foreign intelligence organisation.

Lots more at the link...

It’s a weird story, and the FBI affidavit raises more questions than it answers. The employee only worked for the NSA for three weeks—which is weird in itself. I can’t figure out how he linked up with the undercover FBI agent. It’s not clear how much of this was the employee’s idea, and whether he was goaded by the FBI agent. Still, hooray for not leaking NSA secrets to the Russians. (And, almost ten years after Snowden, do we still have this much trouble vetting people before giving them security clearances?)...

Citizen Lab did the research:

Using only a single website, as well as publicly available material such as historical internet scanning results and the Internet Archive’s Wayback Machine, we identified a network of 885 websites and have high confidence that the United States (US) Central Intelligence Agency (CIA) used these sites for covert communication...
