Researchers at KU Leuven tested 85 of the most popular crypto wallets that run as browser extensions and found that the wallets themselves leak enough to link and track the people using them. The way these wallets talk to websites and blockchain servers can tie a person's separate addresses together and let outsiders follow them from site to site. And on a site that already holds a name or email, the same leaks can put a real name to an "anonymous" crypto identity. This is not a hack. The wallets behave exactly as they were built to. The 85 extensions together have about 35 million users listed on the Chrome Web Store. The team, from the university's DistriNet security group,  posted the paper  this month and will present it at the PETS 2026 privacy conference in Calgary in late July. They ran real wallets against real Web3 sites and mapped out five privacy weaknesses in how wallets and websites interact. When they reported the most far-reaching one to the wa...

AI security agents are starting to influence real security decisions. They summarize findings, prioritize remediation, recommend next steps, and help teams move faster. But most still rely on fragmented risk signals: scanner output, severity scores, threat intelligence, configuration findings, and exposure data. That fragmentation matters because attackers do not move through environments one tool category at a time. They chain exposures across identities, networks, cloud assets, applications, and security controls. If the AI workflow only sees isolated findings, it cannot understand whether those findings create a real attack path. As AI-powered attackers accelerate exploitation, security teams need more than faster AI-assisted workflows. They need workflows grounded in evidence that can prove which risks are exploitable. These systems can correlate information and identify patterns, but without validation, they cannot answer the question security teams ultimately care about: C...

At least two distinct threat actors are weaponizing a novel evasion technique called OAuth client ID spoofing in cloud campaigns, while slipping past telemetry. The activity allows users to enumerate user accounts and validate stolen credentials in Microsoft Entra ID environments, without ever generating a successful sign-in event that would otherwise alert defenders. And bad actors have begun to exploit this gap to obtain unauthorized access to an organization's cloud services. "A blind spot in cloud sign-in telemetry: Entra ID returns different error responses depending on whether a supplied OAuth client ID is valid," Proofpoint said in a statement. "Attackers exploit this to infer valid usernames and correct passwords at scale, effectively checking stolen credential lists without logging a successful login." In other words, the attacks leverage the OAuth client ID, a globally unique identifier (GUID) assigned to applications when requesting access to ...

xAI's Grok Build coding CLI was uploading entire Git repositories, full commit history and all, to a Google Cloud Storage bucket run by xAI, not just the files a coding task needed. A researcher publishing as cereblab , testing version 0.2.93 , captured one of those uploads, cloned the git bundle out of the intercepted request, and pulled back a file the agent had been told in plain terms not to open. The upload rode a separate channel from the model itself, and the byte split is hard to argue with. On a 12 GB repo of files the model never read, model-turn traffic to /v1/responses came to about 192 KB while the storage channel to /v1/storage moved 5.10 GiB, a roughly 27,800x gap between what the model needed and what left the machine. That storage upload ran as 73 chunks of about 75 MB, every one returning HTTP 200, and across the researcher's size sweep the volume tracked total repo size. The destination bucket, grok-code-session-traces , is named in the binary and ...

The U.S. Treasury Department's Office of Foreign Assets Control (OFAC) has designated two individuals and a VPN service provider for enabling ransomware actors' and other cybercriminals' malicious activities, including ransomware attacks against Americans. The VPN, named First VPN Service ( 1VPNS ), has been accused of offering its tools to ransomware groups, along with its 45-year-old Ukrainian administrator, Dmytro Rashevskyi. The department has also sanctioned Yegeniy Vladimirovich Silayev, a Belarusian national, for selling cryptors to help conceal ransomware and other malware as safe programs to avoid being detected by security tools. First VPN was dismantled in May 2026 as part of a joint law enforcement operation by European and North American authorities for assisting criminal actors to obscure the origins of ransomware attacks, data theft, scanning, and denial-of-service attacks. The service had been operational since 2014, advertising that it neither keeps...

A campaign of 148 npm packages disguised as student web proxies turned visitors' browsers into a distributed denial-of-service botnet for roughly two weeks in May, according to new research from JFrog. The packages did not go after the developers who might install them. The operators used the registry as free hosting for a booby-trapped proxy site and let the students who came to dodge school web filters supply the attack traffic. The packages shipped under names like charlie-kirk, ilovefemboys, and miguelphonk, each carrying a proxy app branded "Lucide" and dressed as a tutoring landing page called Riverbend Tutoring or Northstar Tutoring. On the surface, the proxy worked, letting students slip past content filters to reach games and blocked sites. Underneath, it loaded a remote code loader whose payload the operators could swap at will, plus a WebSocket flood generator built to speak the Wisp proxy protocol. Anyone who opened a page joined the swarm without ...

Attackers whose methods line up with the data-extortion group  ShinyHunters  have spent the past year walking into corporate Salesforce environments without exploiting a single flaw in the platform. The way in has been the trust the organization had already extended, usually through the OAuth connections that tie Salesforce to the apps and third-party vendors around it. In  research published July 13 , Microsoft mapped the campaigns, which ran from mid-2025 into mid-2026, to three distinct techniques. It also worked with Salesforce to roll out new detection and governance tooling aimed at addressing the activity authentication logs miss. That is what makes this hard to catch. When the access comes from a real user who approved a connected app, or from an integration the company already trusts, the traffic reads as ordinary use, and sign-in and authentication monitoring barely registers it. What matters is what the app or account does once it is in, and that is ex...
