Since mid-August 2026, a phishing operation has been stealing live Google sessions from corporate users. Every check defenders normally lean on to judge a link came back clean, and the operator designed it that way on purpose. The Threat Research team at Material Security spotted the campaign and has since taken down hundreds of attacker domains in an effort the team calls Operation CloudFire. Here’s what the researchers found. The lure: Google Calendar invites The messages show up as Google Calendar invites. Some arrive by BCC, and many come from an organization the recipient has already traded email with. The pretexts are deliberately boring: voicemail notifications, RFP and RFI requests, court summonses, and missed payment notices. Nothing about them stands out in a busy inbox. Most of the links point to Google itself. The usual pattern runs through Google’s own /url redirector, with the real destination tucked into a query parameter. Other waves used share.google and Driv...

Starting Tuesday, an attacker used stolen credentials for 4,837 GitHub accounts to plant a secret stealer in repositories those accounts could write to, according to Aikido Security, a security software company. The stealer is built to take the secrets and cloud credentials that a repository's CI workflows can reach. It ran in at least 1,806 repositories, where the attacker has likely collected those credentials, the company says. Each attack started with a pull request titled docs: dependency audit notes, opened from a branch named wfx-docs to test whether the account could write to the repository. These test pull requests were opened in 61,764 repositories, and the stealer followed in some of them. In a separate analysis , researchers at SafeDep, which sells software supply chain security tools, counted 8,093 repositories that received malicious commits between 12:46 UTC on Tuesday and 04:36 UTC today. That count covers every repository that received malicious commits, no...

Cybersecurity researchers have disclosed details of a campaign in which an emerging agentic penetration testing platform called AntiFox has been used to steal Amazon Web Services (AWS) credentials and pivot laterally into compromised environments. "In several recently observed intrusions, Alibaba Cloud systems hosting AntiFox interfaces were associated with confirmed malicious actions against internet-facing web services and associated AWS environments," Arctic Wolf Labs said in a report shared with The Hacker News. The activity has been observed chaining together web exploitation and web shell deployment to facilitate configuration discovery, credential validation, cloud-service enumeration, secret access, and storage operations. AntiFox, available for download from GitHub, has been described as an artificial intelligence (AI)-driven autonomous penetration testing platform that's built atop the "solid foundation" of ARTEX . As of writing, the project...

Of the 37,571 Grok-built apps that security company Claroc found online, 35,578 were open to anyone without a sign-in, the researchers said yesterday. They included 24 apps built by staff at the social network X and at SpaceXSI, the company that makes the Grok AI assistant. Most of the open apps were games, landing pages, and calculators, but about 1 in 10 contained internal business or personal data. The staff apps included a confidential onboarding plan for a new sales hire, a sales territory map of 594 accounts, and an X advertising proposal to a U.S. federal agency marked confidential. SpaceXSI, formerly known as xAI, has since taken down all 24 staff apps but not other users' apps, the researchers said. Besides those staff apps, the open apps contained internal data from 30 other organizations the researchers could identify, across fields ranging from construction and energy to healthcare and defense. Of those, 26 have more than 1,000 employees, and 6 are Fortune 500 co...

AI provider keys that customers stored on Railway were stolen in an October breach and used to commit an estimated $740,000 in unauthorized spending, the platform-as-a-service provider said yesterday. It has promised to pay those charges itself when an AI provider will not refund them. The company builds and runs apps for its customers and stores their secrets, such as API keys and database credentials, as environment variables. The attacker decrypted variables in at most 1.85% of workspaces, about 100,000, and its database queries looked for AI provider keys. In an October 26 update, the company told customers asking about refunds for unauthorized AI spend that "Railway is unable to refund customers for spend performed with compromised API keys." It encouraged them to contact the AI providers directly and offered to escalate their requests. According to the company's incident report , the decrypted data also included linked-account tokens for 1,852 users: BYOK age...

An attacker exploited a remote code execution flaw in SGLang , an open-source inference engine, and ran code on one of NEAR AI's inference servers last Sunday. The attacker could also have seen requests being processed on that server that day, including requests sent in confidential mode, the company said earlier this week. That mode processes requests inside a trusted execution environment (TEE) designed to keep them private even from the company itself. But the TEE "does not protect against a vulnerability in the software running inside the environment," the company said. SGLang runs inside the TEE, which is how the attacker could reach requests there. That access has since been closed, but not before the attacker moved further into the company's systems. The attacker reached an internal system behind Private Chat, a product the company had already deprecated. So far, the company has confirmed that the attacker downloaded account details for about 100 users...

Fireworks AI disclosed on Monday that its investigation into a security incident first reported early last month  uncovered further malicious activity, affecting account and billing information, alongside secrets, datasets, and incomplete models for a "limited set of accounts." In a notice published on October 10, 2026, the company said it detected unauthorized use of internal Fireworks credentials that allowed an unauthorized third-party to access environment variables used in evaluation jobs in a limited number of customer accounts. The activity was detected on October 6, 2026, at 9 a.m. PDT. At that time, the AI infrastructure provider said it only found evidence that environment variables, including API keys and tokens stored as secrets, were captured in certain affected accounts, adding that there were no signs that customer models, datasets, training data, inference traffic, or personal information were accessed. In response to the incident, Fireworks AI took th...

An attacker broke into AWS accounts belonging to multiple Qubole customers between October 14 and October 26 and stole stored secrets and data, cloud security company Wiz said today. The attacker used credentials for an AWS account that Qubole's platform uses to reach those customers. How the attacker got those credentials has not been disclosed. Qubole , a data lake platform owned by Idera, operates within its customers' AWS accounts. To let it in, a customer creates an IAM role, which is an AWS identity with its own set of permissions. The role's trust policy allows Qubole's AWS account to assume the role, granting those permissions. Each request to do this, called AssumeRole , must include a matching code from Qubole known as an External ID. Apart from the attack, most of the roles the attacker assumed were unused, according to Wiz's researchers. But each role still trusted Qubole's account, so the attacker's requests worked. Any organization...

A system doesn't always need a complicated bug to let someone in. Sometimes, a blank password is enough. That's one of the bigger stories this week. And it gets worse when the tools meant to keep systems updated or running safely become part of the attack. Elsewhere, attackers are hiding inside normal web traffic, stealing credentials from network devices, and finding new uses for exposed systems. AI is helping some of them move faster, but old mistakes are doing plenty of the work too. Even forgotten settings and small changes made months ago are coming back to cause trouble. There's a lot packed into this week's news, including some strange research findings, fresh attacks, and a few warnings worth taking seriously. Here's the full recap. ⚡ Threat of the Week OpenSSH Flaw Sees Exploitation Attempts — Threat actors are attempting to exploit a recently disclosed security flaw impacting OpenSSH that can enable sign-ins to accounts that have no password set....

Passwords and API keys that developers typed into commands they approved in Claude Code are sitting in public GitHub repositories, where anyone can read them. When a user selects " Yes, and don't ask again ," Anthropic's AI coding assistant can save the command, word-for-word, including the secret, in a project settings file. Software security company Apiiro said yesterday that 1,122 public copies of that file hold at least one secret, though it did not test whether any still work. One company the researchers notified earlier this week confirmed its key had been live. The file is .claude/settings.local.json. Removing it from a project does not undo the leak, because older versions stay in git history and in forks of the repository. The researchers' advice is to rotate first: change every password, token, and key the file has ever held, then clean up. How a Secret Lands in the File By default, Claude Code asks before it runs most shell commands. If the u...

Blockchain analysis firm Chainalysis has revealed that its ongoing investigation into the agentic cyber attack targeting its systems also exposed names, usernames, password hashes and live tokens for all users. "While we investigated, we removed access to Reactor and Data Solutions," the company said. "At this time we continue to have no evidence that any investigations data has been accessed or Chainalysis attribution data has been manipulated." Chainalysis said it has implemented additional proactive monitoring systems to detect unusual activity, adding it took the Know Your Transaction (KYT) user interface and API offline, alongside other address screening products and the login page. Previously, Chainalysis said it was probing what it described as an "ongoing multi-front cyber attack," leading to the discovery of an "on-path attack" that exposed a subset of customer passwords. The company said the attack vector has since been addres...

How much damage can someone do without breaking much? Quite a lot, it seems. A stolen login can open doors across several systems. A trusted setting can be used to lock people out. Even a simple file copy can reach places it shouldn't. And while new tools are helping find security holes faster, some important systems are still taking months, sometimes over a year, to get patched. Not exactly a great match. The stranger part is how little some attacks now need. Ransom demands without encrypted files. Fake websites that look real enough to steal money. AI tools picking up dangerous instructions while trying to help. Even the attackers are making mistakes in their own code. This week's stories are a reminder that the biggest problems don't always come from clever tricks. Sometimes the easy way works just fine. Here's what else happened. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

A critical finding can move through several security tools and still leave the organization exposed.  The vulnerability has a severity score, and a ticket has reached the queue. Progress then depends on information the finding may lack: who owns the system, whether attackers can reach it, what protection exists, and how a change could affect the business.  Each missing detail creates another investigation, another handoff, and another delay.  An exposure management platform should connect discovery with a clear priority, an appropriate response, and evidence that protection has improved.  Continuous threat exposure management (CTEM) connects this work through scoping, discovery, prioritization, validation, and mobilization. These five tests establish whether a platform can support that process across infrastructure, identities, sensitive data, and external threats. Security teams often have several records of the same asset. A cloud platform identifies ...

Apple has revealed that it plans to start checking public iCloud links for harmful content starting with iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3. The change specifically applies to scenarios where users share iCloud content, such as photos in iCloud Photos or files in iCloud Drive, by sharing a link and making it accessible to "Anyone with the Link." When users choose this option, it makes the content accessible to anyone who has the link, including Apple, the iPhone maker said. "Starting in version 27.3 or later of iOS, iPadOS, macOS, and visionOS, items shared using Anyone with the Link will be checked by Apple for harmful content," it said in a support document published Tuesday. Apple also explicitly noted that sharing an item that can be accessed by "Anyone with the Link" disables end-to-end encryption (E2EE), even if the owner or the recipients have turned on Advanced Data Protection , an optional setting that secures iCloud Ba...

The Indian Computer Emergency Response Team (CERT-In) has disclosed that an artificial intelligence (AI)-assisted threat actor it tracks as Crafty Falcon is targeting organizations in the Banking, Financial Services, and Insurance (BFSI) sectors in the country. Describing the threat as active and ongoing, the activity involves the use of publicly-available AI-driven offensive security tools like ARTEX, PentAGI, Cairn, and CyberStrikeAI . "These tools execute complete attack chains autonomously at machine speed, generate and refine large numbers of tailored attack scripts in rapid succession, and adapt their payloads based on target responses," CERT-In said . "The supporting attack infrastructure rotates IP addresses within hours to days." The agency said the attacks have also targeted cryptocurrency exchanges and digital asset service providers, resulting in the theft of keys and funds. The update follows an October 2026 alert issued by CERT-In, which wa...

Two flaws in the Xen hypervisor allow a malicious guest virtual machine (VM) to read and write the memory of other VMs on the same host, including dom0. Dom0 is the VM that, by default, has full permissions and manages the others. Patches are out, and there is no known mitigation, the Xen Project said in an  advisory  on November 3. All Xen versions from 4.6 onward are vulnerable, while 4.5 and earlier are not. The flaws are tracked as CVE-2026-102703 and CVE-2026-102704 , under Xen advisory XSA-523. The Xen Project credited AI company Anthropic with finding the flaws using its Claude model. Stephan Lipp of Ada Logics then validated the finding, and the CodeAnt AI Security Research Team later independently reported the same issue. The flaws are in grant copy, the operation Xen uses to copy data between VMs. Each VM tells Xen which of its memory pages other VMs may use, and Xen checks those permissions. To save time on a batch of copies within the same memory page, ...

Nearly every agent security pitch now ends on the same promise: the product stops the bad action in real time. The promise holds for one kind of agent, the kind whose traffic passes through a gateway the enterprise owns. Most agents never touch one. One recent case shows what that gap looks like in practice. An employee asked an AI assistant to trigger a mass-email automation. The automation hit a recipient-limit policy and failed, so the assistant, which was also connected to the employee's personal mailbox, offered to send the batch from there instead. The employee approved without registering that the assistant was about to route around the sanctioned system. An unknown number of external recipients received email from a personal account rather than the approved channel. No jailbreak was involved. The assistant did exactly what it was built to do, and the fix was not retraining a model. It was a single runtime rule that blocks any attempt to reach more than fifty external d...

Blockchain infrastructure provider Chainstack on Tuesday disclosed that it was targeted in a cyber attack that allowed an unauthorized party to gain access to some parts of its infrastructure. The incident is assessed to be part of a large-scale, artificial intelligence (AI)-powered attack campaign that came to light last week. "An external attacker gained unauthorized access to part of Chainstack's infrastructure through a third-party component," the company said . "We detected the intrusion, cut the access paths, and are hardening our systems." According to the timeline of events shared by Chainstack, the attacker gained access to a development environment on October 26, 2026, and then escalated their access to break into "some parts of our production environment." The intrusion was subsequently detected on October 31, 2026, and the attacker's access was cut off that same day, the company noted. As part of the digital break-in, the ...

Google on Monday warned that threat actors are hijacking enterprise access to Large Language Models (LLMs) to fraudulently leverage expensive computing resources and AI services. The tactic is called LLMjacking , a form of resource hijacking adapted for the LLM era, where an attacker obtains an API key through phishing, source code leaks, misconfigured environments, or exposed client-side code to gain unauthorized access to an organization's LLM accounts, while the legitimate owner covers the consumption costs. Such attacks have a wide geographical footprint, with impacted entities located in North America, South America, and Asia Pacific across the financial services, retail, technology, and transportation sectors. "Unlike the gradual resource consumption associated with cryptojacking, LLMJacking can generate large spikes in fraudulent cloud charges in a matter of hours," Google Threat Intelligence Group and Mandiant said in a report shared with The Hacker News...

Some attacks this week didn't need much of a trick. A fake support call, a trusted extension, a shared link, or a device with no password. Small things that people barely think about. Yet each was enough to cause serious trouble. Then there were the bigger messes. Billions stolen, hidden networks of hacked devices, poisoned software, and attackers finding new ways to turn normal tools against their users. Even the places meant to keep money and systems safe ended up with problems of their own. The strange part is how often the damage started somewhere nobody was looking. And that's before getting to the long list of fresh bugs, shady services, and scams making the rounds. Quite a bit to sort through. Here's what made the list. ⚡ Threat of the Week N. Korea Sets New Record with Binance $6.43B Crypto Theft — The U.S. Federal Bureau of Investigation (FBI) has officially attributed the theft of more than $6 billion in virtual assets from Binance to a North Korean hack...
