Critical TeamCity Flaw Could Let Attackers Run OS Commands Without Logging In

JetBrains is urging customers of on-premise versions of TeamCity to update to the latest version following the discovery of a critical security issue that could result in arbitrary code execution.

The vulnerability, assigned CVE-2026–63077 (CVSS score: 9.8), affects all TeamCity On-Premises versions. It has been addressed in versions 2025.11.7 and 2026.1.3. TeamCity Cloud instances have already been updated. JetBrains has credited Antoni Tremblay with discovering and reporting the flaw on July 10, 2026.

“If exploited, this flaw may enable an unauthenticated attacker with HTTP(S) access to a TeamCity server to bypass authentication checks and execute arbitrary operating system commands with the privileges of the TeamCity server process,” JetBrains said.

Intel Emerges as America’s Only LeadingEdge Chipmaker as RAMPC Hands the Department of War Domestic 18A Production

Intel has completed its RAMP-C program, which now aims to enable customers to move from test chips to domestic high-volume manufacturing.

Press Release: Intel Foundry has completed the Rapid Assured Microelectronics Prototypes — Commercial (RAMP-C) program. Launched in September 2021, the program supported development of domestic, leading-edge CMOS technology and manufacturing in the United States, establishing a foundation for expanded trusted domestic semiconductor manufacturing.

Insect-inspired electronic nose: Turning semiconductor chips into olfactory sensors

Bioengineers at the University of California San Diego integrated the olfactory receptor of an insect called a jumping bristletail into semiconductor chips made of graphene, creating an electronic nose capable of sniffing out a wide variety of small organic compounds. This biomimetic bioelectronic sensor can detect and distinguish between molecules that are difficult for conventional electronic sensors to differentiate. This work opens the door to building semiconductor-based chemical sensing systems inspired by nature for applications in health care, environmental monitoring, food quality, agriculture and biodefense.

In a paper published in Advanced Materials, researchers led by bioengineers at UC San Diego describe a method for manufacturing the MhOR5 odorant receptor from the insect Machilis hrabei at scale and chemically attaching the purified MhOR5 protein to high-performance graphene field effect transistors (gFETs). gFETs are semiconductor devices that rely on graphene instead of silicon as the conductive material, resulting in exceptional sensitivity to molecular changes.

The researchers tested their MhOR5-functionalized gFETs against 16 chemically diverse compounds, including DEET, hexanol and eugenol, at different concentrations. The sensor produced a concentration-dependent electrical response for each of the 16 compounds.

New quantum chip architecture could use built-in vibrations to link distant qubits

A new concept from Warwick researchers could help solve one of the biggest challenges to building large-scale quantum computers: enabling communication between vast numbers of quantum bits (qubits) over long distances across a single chip.

Published in APL Quantum, researchers from the University of Warwick and NRC Canada introduce the concept of Quantum Phononic Links (QPLs), a new approach to communication between qubits. It uses sound-like vibrations traveling through a specially engineered material to carry quantum information between qubits that are physically far apart.

Today’s leading quantum chips typically allow only neighboring qubits to communicate directly with each other. To build useful quantum computers, engineers expect to need to coordinate millions of qubits spread across an entire semiconductor chip, not just clusters of adjacent qubits. The team’s proposed approach uses sound vibrations, known as phonons, as an inherent communication system, allowing qubits to exchange quantum information over much greater distances than currently possible.

New sensing method measures laser-cutting depth by tracking vaporization recoil

Laser dicing, a technique that uses focused laser pulses to separate individual chips from a semiconductor wafer, is increasingly favored over mechanical blade cutting because it can process delicate, low-strength materials with minimal physical stress. However, achieving proper yield requires precise control over the process.

If pulses fall short, they leave a wafer only partially cut, while excessive pulses can damage the material or the tape used to hold it. While techniques for monitoring processing depth exist, most are too slow or fragile for use on production lines.

Now, a team of researchers led by Professor Hirofumi Hidai from the Graduate School of Engineering, Chiba University, Japan, focused on a different signal: recoil force. Recoil force is the minute reaction force generated on a material’s surface when it is rapidly heated and vaporized by a laser pulse.

Steam forum ClickFix attacks infect gamers with XMRig cryptominers

Steam discussion forums are being abused in ClickFix attacks that pretend to be fixes for game and computer problems but actually infect devices with cryptominers.

BleepingComputer learned of the campaign from a reader, who told us threat actors are creating random Steam accounts to post what appears to be helpful fixes for people’s posts about games crashing, lost inventory items, and other technical issues.

The threat actors reply to posts, telling other members to open PowerShell as an administrator and run a command to fix the issue. However, when executing the command, it quietly downloads an XMRig miner executable and launches it on the computer.

Malaysia’s resource anxiety tests Asia’s fastest data center build-out

HONG KONG/JOHOR, Malaysia – After leapfrogging Singapore to become the region’s fastest-growing data center hub, Malaysia is facing intensifying scrutiny as the resources debate that has complicated the industry’s growth spreads to emerging Asia.

Protests over a data center complex in Johor state’s southern tip — the epicenter of the boom — were the first of their kind in the country. In Selangor, the richest and most populous state, debate about the burden on communities has become politicized.

“Two years ago, it was just about building capacity,” said Cheam Tat Inn, managing director at the Malaysian arm of U.S. data center operator Equinix.

Brain waves once seen as noise could help build a biological model of reality

Your brain has something surprising in common with the ocean: waves. Electrical activity washes over the brain’s surface, creating what are called traveling brain waves, or neural traveling waves. These waves cause real differences in your behavior and attention and—again, like ocean waves—can have variable causes, from intrinsic activity to environmental inputs.

A new review article by Salk Institute neuroscientists synthesizes physiological and computational information about these neural traveling waves and draws a new conclusion: Neural traveling waves are a computational engine in the visual cortex. These waves allow the visual cortex (and likely other areas of the brain) to build representations of the external world, enabling our capacity to predict, reconstruct and perceive the world around us.

The piece was published in Neuron on July 21, 2026.
