Claude Mythos flags 23,019 software flaws: 21,000 still await human review

By June 2026, Anthropic said its AI system, Claude Mythos, had produced 23,019 vulnerability reports across open-source software. Only about 1,900 had been reviewed by outside parties. That meant more than 21,000 findings were still unverified. Even so, Anthropic says 1,726 of the reviewed reports turned out to be real vulnerabilities, which helps explain why AI-driven bug hunting can feel like a real shift in security work. But people still have to do the hard part, because severity was often rated too high and the choke point is moving away from discovery and toward validation and patching.

That need for human review shows up pretty clearly in the severity calls. Across 27 Common Vulnerabilities and Exposures, or CVE, cases, Anthropic’s Claude Mythos labeled eight as critical. After review, only one of those still counted as critical, and 13 of the 27 original ratings were judged too high. Temporal Server is a good example. A flaw there was first tagged as critical, then later dropped to low because exploiting it depended on rare setups, unusual deployment conditions, or privileged access. At that point, maintainers still had to sort out exploitability, business impact, and patch priority.

Anyone who follows software security should keep an eye on this, because the bottleneck is shifting from finding bugs to checking them and fixing them, and monthly CVE disclosures rose 145% in the two years leading up to June 2026. These reports hit open-source projects, not some consumer app download page, and researchers are divided. On one side, cheaper and faster auditing. On the other, the risk that machine-generated disclosures will swamp teams, maintainers, and bug bounty programs as the number of discovered bugs keeps climbing.

Canadarm is now the 300th IEEE Milestone for 2026

The original Canadarm has picked up another honor. IEEE, the Institute of Electrical and Electronics Engineers, has named the Canadian-built robotic arm from the Space Shuttle its 300th Milestone for 2026, recognizing a technology that marked a major technical achievement and left lasting benefits for society.

It also puts the spotlight back on the role Canadarm played in NASA’s Space Shuttle program. According to NASA, the arm flew on 90 of the shuttle’s 135 missions, where it was used to deploy, retrieve, and repair spacecraft and other payloads in orbit.

Canadarm first flew in 1981. NASA describes it as the world’s first spaceborne robotic system. At 15.2 meters long and 410 kilograms, it could handle payloads of up to 266,000 kilograms in microgravity, and do it with remarkable precision.

That turned Canadarm into one of the signature tools of the shuttle era. It made delicate, difficult, risky, and sometimes flat-out impossible jobs possible, including major work on the Hubble Space Telescope. NASA and IEEE both point to that record when they describe how the arm helped turn the shuttle into a true orbital work platform.

For anyone who follows spaceflight history, this is a fitting piece of recognition. Canadarm was built by SPAR Aerospace, now part of MDA Space, for about $108 million, according to IEEE. Over time it became a Canadian engineering icon and a cornerstone of Canada’s partnership with NASA. Few pieces of space hardware have had a run this long, or this influential.

That legacy is still easy to trace. You can see it in Canadarm2 and Dextre aboard the International Space Station, in Canadarm3 for Artemis lunar missions, and in the milestone coverage from IEEE and NASA. So far, most of the reaction has come from North America, much more than from the European Space Agency, the Japan Aerospace Exploration Agency, or Roscosmos.

FBI cripples China-linked hacking network: NASA, DOJ and Senate among targets

The FBI says it has disrupted the QScan and QTRouter network, a system authorities say had been used since at least 2018 to go after NASA, the US Department of Justice, the Federal Reserve, the US Senate, the US National Institutes of Health, and other American agencies and pieces of infrastructure.

Court filings say FBI agents seized malware-linked domains to cut off attacker communications and knock both platforms offline. Investigators connect them to QTFY, which the US Department of Justice identifies as part of Nanjing Xinjiuwei Network Technology Company. US officials say that company is tied to China’s Ministry of State Security and the People’s Liberation Army. Beijing denies those claims.

Officials say QScan was used to find and compromise exposed IoT devices, especially small office and home office routers and cameras. QTRouter then used those hacked devices as relays across more than 130 countries, making the traffic look local, or at least not like it was coming from China.

If you’ve got smart devices at home or at work, pay attention to this. Change default passwords, install firmware updates, and replace hardware that no longer receives patches. the warning comes as the US keeps moving against Volt Typhoon, Flax Typhoon, and Mustang Panda.

You can read the court documents, along with statements from the FBI and the US Department of Justice. US officials say the takedown hits an operation that helped cover up years of intrusions into American targets.

GPUThor disclosed: it bypasses ECC on NVIDIA RTX workstation GPUs

Researchers disclosed GPUThor today, a GPU-based Rowhammer attack that targets GDDR6 memory on NVIDIA Ampere workstation GPUs. In their write-up, repeatedly hammering that memory caused bit flips that led to corruption, crashes, and, in one demonstration on an NVIDIA RTX A6000, a full compromise of the host.

They say GPUThor works on RTX A4000 , RTX A4500, RTX A5000, and RTX A6000 cards. It can also push error-correcting code, or ECC, past what it can reliably handle by forcing multi-bit errors, cases that may be detected but not corrected, or even silently corrected the wrong way. In the researchers’ testing, GPUThor was roughly 4,548 to 23,597 times more effective than the earlier GPUHammer technique at producing exploitable flips directly on the GPU.

If you’re running shared cloud, research, or high-performance computing GPU workloads, this deserves real attention. In the team’s tests, an unprivileged program was able to corrupt GPU page tables, turn GPU memory corruption into root-level access on the host, and also trigger GPU resets about every two hours. In some cases, it eventually went far enough to raise hardware-replacement flags.

The researchers say the findings affect NVIDIA GDDR6 workstation setups. NVIDIA recommends ECC along with input-output memory management unit, or IOMMU, and direct memory access, or DMA, isolation. The paper argues that operators may need more than that, including stronger multi-bit ECC, DRAM-level mitigations, close monitoring of ECC error logs, and tighter controls on untrusted GPU workloads.
