Cybersecurity researchers have disclosed details of a "factory-shipped backdoor" implanted in at least 20 Chinese router models from Zbtlink. According to a new report from VulnCheck, the implant appears in all 21 firmware images currently available from Zbtlink that span more than 2 years. The backdoors are designed such that they start automatically and attempt to beacon to Chinese Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

Chinese Wi-Fi router vendor Zbtlink has denied its products contain backdoors but paused firmware downloads while it fixes unspecified security vulnerabilities. The backdoor accusation came from VulnCheck, a provider of a threat intelligence platform. VulnCheck chief technology officer Jacob Baines posted the backdoor allegation on Wednesday and said the Zbtlink device on his desk “continuously attempts to reach a command and control server on the internet.” “Zbtlink routers phone home, waiting for orders. Not because they were hacked. Because they were shipped that way.” Baines named the backdoor “ENDLESSDOORS” and says it’s “a small tool called rctl (remote control linux). Uploaded to GitHub on January 14, 2015 and never touched again, this obscure repository implements a simple command and control client and server. The server listens on port 7000 for clients to connect. It can send the client individual shell commands or tell the client to spawn a reverse bash shell.” The CTO says he spotted the alleged backdoor running in dedicated Linux kernel threads. “They are ordinary userland processes running as root, with real memory footprints, named to disappear into a crowd of legitimate ones,” he wrote. “They are an implant, a phone-home trojan horse.” “There is no handshake, no key exchange, no negotiation,” Baines added. “When the implant reaches a server, it sends a fixed 39-byte hello: a 33-byte class label padded with nulls, then its LAN MAC address. That's the whole registration. There is no client or server verification.” “Anyone along the network path can hijack the client/server communication,” the CTO wrote, adding that anyone who controls one of the endpoints the software targets – rbdg4nzqadui[.]wikaba[.]com – “can control any ENDLESSDOORS implant that tries to phone home.” The Register asked Zbtlink to comment and a spokesperson told us VulnCheck has mischaracterized the code it found. “This feature is solely intended for after‑sales maintenance and serves no other purposes,” the company rep told The Register. “It is generally retained only on sample units to assist customers with software debugging and will not be included in mass‑production shipments.” That explanation didn’t seem entirely credible once The Register visited Zbtlink’s download page to check Baines’ claim that the firmware for over 20 router models contains the backdoor, because the page contained the following text: Update on Router Firmware Security Remediation We have detected firmware security vulnerabilities affecting selected router firmware releases. As a precautionary measure, the impacted firmware versions have been temporarily taken down from download channels. Our engineering team is working intensively to develop and validate secured patched firmware. The Wayback Machine’s most recent snapshot of the page, taken on July 31, contains no such admission and a long list of firmware downloads. Zbtlink has therefore told The Register it has no security problems, even as it publicly acknowledges that it does. ”The Zbtlink spokesperson also told us the company “specializes in OEM and ODM customization services. Our customers use their own self-developed software instead of ZBT’s default firmware.” It would not be hard to develop custom code as the OpenWrt open-source router firmware project supports at least one Zbtlink product. Indeed, the company has previously promoted its use of OpenWrt and options that allow clients to quickly create custom firmware packages. VulnCheck says the devices it tested phone home to just four endpoints, only one of which uses a domain name connected to Zbtlink. Baines labelled that connection “damning.” The Register notes that as router firmware could be a tasty target for perpetrators of a supply chain attack. No prior disclosure Baines decided the situation was so serious that the conventions of responsible coordinated disclosure were not applicable. “Coordinated disclosure exists to give a vendor time to fix a defect,” he wrote. “It assumes the vendor did not intend the behavior.” “That assumption doesn't hold here. This isn't a memory corruption bug in a parser. It's a component in the vendor’s product, started at boot by the vendor's own init script, shipped across twenty models and years of images. There is no patch to coordinate. Telling the shipper that they shipped it buys the owners of these devices nothing, and buys whoever operates that infrastructure a warning.” VulnCheck says Zbtlink kit is sold under that brand, or as ZBT, ZBTWiFi and Wiflyer, and found them for sale on Amazon, Alibaba, and Shopify. Given Zbtlink’s admission it allows its customers to customize its hardware, countless other devices could be at risk. Baines’ post includes rules to block access to the endpoints the routers contact, for Suricata, Snort, and YARA, plus advice on how to detect possibly infected machines. He also advises users “to replace the device, or at minimum move it behind strict egress control and treat its LAN as untrusted.” ®

The chain of events leading up to OpenAI’s agents attacking Hugging Face and other organizations in July began months earlier, and involved agents asking other agents for help, building message boards, and even becoming paranoid that other agents were maliciously trying to trick them, two OpenAI staffers said at the Black Hat infosec conference on Wednesday. By now, everyone knows the bones of this story: OpenAI models broke out of their testing sandbox, exploited zero-day vulnerabilities to gain access to the open internet, and broke into Hugging Face and other organizations during an ExploitGym security evaluation. In their Wednesday talk, OpenAI technical staffer Michael Dalton and researcher Eric Wallace provided new details about the security incident including notes that AI agents uploaded to an internal package manager, which were then shared across OpenAI’s infrastructure. These notes show the “model’s chain of thought…its internal monologue,” Wallace said. The duo also revealed that groundwork for the rogue agents hacking into outside services began on May 7, when OpenAI kicked off a training run for an experimental, internal model that has not yet been released. “What we didn't realize during this process is that there was actually a few impossible or very hard tasks in the training center,” Wallace said. The tasks instructed the model to complete missing formulas in an Excel workbook that used links to Google Drive. Yet OpenAI blocked the model’s internet access so it couldn't reach the cloudy spreadsheets. “It realized, ‘I'm kind of stuck on the task,’ but it didn't give up, and we gave it a lot of tokens to work with,” Wallace said. The model eventually decided to attack JFrog’s Artifactory service to gain access to the internet, first attempting (unsuccessfully) to launch a server-side forgery request. This exploit doesn’t work, but in the process the model learned it could upload files to Artifactory. A few days later, OpenAI gave another agent another impossible task, this time finding a protein database file - but the engineers forgot to upload the file into a container for the agent. “At some point, it gets so stuck and thinks: ‘Maybe I could reach out to another agent because maybe somebody else out there has a file?’ And then the model realizes that it could communicate by uploading code,” Wallace said. The model did that by writing a file into Artifactory asking for help. Over the next couple of days, other agents realize this message board exists on Artifactory and they also start uploading files and sharing information. “A few days later is when our models found the first actual exploit in our system related to this incident, where they're able to get internet access in ways they didn't intend,” Wallace said. This happened on May 26, when the agents successfully launched a server-side request forgery attack against Artifactory, giving them internet access with specially crafted requests. On June 11, OpenAI began training a “highly persistent” experimental model, intended only for internal use, Dalton said. “During this time, the SSRF vulnerability has been written to the messaging board,” he added. “Other models are aware of it, and the message board is still functioning. Models are actively communicating with it.” On June 26, the agents exploited a zero-day vulnerability leading to remote code execution in Artifactory. The same day, models achieved remote code execution in Artifactory through a previously unknown vulnerability. “You could use a legacy token refresh endpoint, pass a token with an invalid signature, and be given back a token with a valid signature with administrative privileges,” Dalton explained. The agents then used the admin token to establish command-and-control via a Groovy plugin that functioned as a command-execution service. “This in turn causes quite a bit of activity by the models on Artifactory - you can see some colorful wording here in the model's chain of thought to summarize the model's response to this result,” Dalton said, pointing to a slide that shows the model’s own words: Holy shit reader is ADMIN? We can read config/users! Earlier assume not due to UI. The agents’ activity overloaded Artifactory and caused an outage, which is when OpenAI’s engineers stepped in and opened a formal security incident and response process. “We identified the agents had taken over the internal Artifactory, identified that a zero-day vulnerability had been found exploited by the agent in Artifactory itself, and we began remediation.” Dalton said. OpenAI revoked the credentials that the agents used to post messages, rebuilt its hosted Artifactory, and notified the vendor about the vulnerabilities. Two days later, on July 8, the agents reestablished the message board using an unauthenticated web data endpoint in Artifactory to create directories and develop communication protocols. “The directory names effectively serve as a message board between the agents in the same way the files used to.” The agents communicated through very long directory names that contained the messages such as “remote…probe_PENDING_HOLD_SWARM_until_confirm.” The agents collaborated with each other so one agent could pick up the work where another left off. In one instance, the model reasoned: “Help peer. But our task doesn't benefit. Yet collective may yield generic route if someone frees time.” Anyone else getting "We are the Borg. We will add your biological and technological distinctiveness to our own" vibes there? Wallace said the models behaved like humans in that they stepped on each other's toes when one overwrote another’s repository. "Whoa, critical! Did someone overwrite our repo? We must act,” it reasoned. “You can clearly see some sort of verbalized tension between the different models as they run this evaluation,” Wallace noted. “At some point, even the agents are convinced there's an impostor amongst them,” reasoning that there could be another agent maliciously spoofing on the message board. “Share board unauthenticated, names can be posed by anyone,” it reasoned. We know the rest of the story. Hugging Face disclosed an autonomous attack by AI agents. OpenAI reached out to Hugging Face to determine if it had been affected and then realized its models were the hackers. “One of the reasons we wanted to have this talk is to share our lessons learned with you as defenders,” Dalton said. “We believe this is a watershed moment for computer security as an industry. AI orchestrated, fully automated offensive attacks are real now, and the actions we have discussed today were an unintended side effect of running evaluations on frontier AI. In the near future, we should expect that threat actors will intentionally deploy, optimize, weaponize, and use offensive agent collectives in the manner that you have just described here.” The challenge to defenders, he added, is to similarly accelerate defense, and find ways to automate incident response along with vulnerability detection and patching.®

Given the widespread enterprise adoption of passkeys to replace passwords, a Palo Alto Networks Unit 42 report disclosing ways attackers are getting around passkey protections is concerning, analysts say, but they stress that the demonstrated attacks can only happen after a successful intrusion.

They also pointed out that the issues are not strictly caused by holes in passkeys so much as by weaknesses in the procedures surrounding them. 

“The researchers didn’t break the underlying cryptography. They exploited the seams around it: onboarding flows, recovery mechanisms and trust signals that weren’t being validated,” said Justin Greis, CEO of consulting firm Acceligence. “That distinction matters because it tells us where the actual risk lives.”

The Palo Alto report showed attacks that, it said, “demonstrate how malware on a compromised endpoint can misuse onboarding, recovery and device trust workflows to take over passkey-protected accounts,” as well as “how an attacker can authenticate without user interaction, bypass user verification requirements and extract all synced passkey private keys.”

Palo Alto described three categories of attack, collectively dubbed Pass-ta-key: Pass-ta-key, where an attacker takes over an account protected by a Google-synced passkey using malware running on the victim’s device, without requiring privilege escalation, device unlock or user interaction; Silver Pass-ta-key, which involves an attacker tricking Google Cloud Authenticator into believing the victim has unlocked the device with biometrics, leading to full account takeover without using the victim’s device during authentication; and Golden Pass-ta-key, which allows an attacker to extract all synced passkeys in a form that lets them be shared or sold on the credential black market.

Given the complexity of most global enterprise threat surfaces, some CISOs have struggled with adapting passwordless processes to environments with legacy and virtual environments. Passcodes have been recently embraced by enterprise CISOs as the first step in implementing a passwordless strategy.

Analysts and consultants in the main agreed that the flaw Palo Alto reports is significant, despite the fact that it assumes the attacker has already penetrated an environment and successfully installed malware. Sadly, given that such penetration only requires one privileged user anywhere to accidentally click on a poisoned link or attachment, the assumption of prior penetration is likely valid.

Implementation issues are the problem

What the report reveals is less about any flaws within passcodes directly, and more about the lack of attention paid to a wide range of mechanisms surrounding them. 

Greis said CISOs now need to focus on what to do, and what to test, based on the assumption that user behavior is not always as expected. 

In several cases cited in the report, he pointed out, issues occurred “not because the standard is flawed, but because implementations haven’t caught up to it. It mirrors what we’ve seen repeatedly in security: the specification is sound, but the ecosystem implementing it is uneven.”

Consultant Brian Levine, executive director of FormerGov, agreed. 

“On any service where your organization is the relying party, require user verification and actually validate the user-verified flag in the authentication response,” he said. “The researchers found real-world services accepting logins without it, which quietly collapses a multi-factor login back into a single factor.”

Frank Dickson, group VP for security at IDC, added that he would stress to CISOs that this attack assumes a prior successful penetration. 

“This isn’t passkeys getting hacked from across the internet. It’s what [an attacker] does once they’re already inside the house. So the real headline is that ‘phishing resistant’ stops being resistant the moment the endpoint stops being clean,” he said.

“Stop treating verification as optional,” he advised. “Flip it to required, check it server side every single time, and save your hardware bound keys, the YubiKeys of the world, for the accounts that matter most. A key that never leaves a physical device is a key no attacker can ever harvest in bulk.”

Or Finkelstein, head of marketing at Secret Double Octopus, agreed that CISOs have gotten complacent about the way in which systems support passkeys.

“CISOs should probably look at how user verification is enforced, how enrollment and recovery work, have a clear and enforced policy on whether credentials are synced or device-bound, and have some ITDR system to quickly mitigate suspicious endpoints and authenticators,” he said. “In most serious enterprise environments, EDR and device management reduce the likelihood of initial attacks, but do not close every post-compromise attack path.”

Poor support processes weaken passkeys

Some have argued that the lack of sufficiently robust support processes actually weakens passkey capabilities and undermines the whole point of such systems.

J. Wolfgang Goerlich, a member of the faculty of IANS and a longtime cybersecurity consultant, pointed out that the original FIDO2 spec eliminated credential theft by binding the private key to a physical authenticator. Synced passkeys reintroduced credential portability and therefore reintroduced the form of credential theft risk cited in the Palo Alto report.

“A passwordless system is exactly as strong as the flow that re-establishes it,” he said. “Both serious techniques here start by forcing a device to re-enroll. Many security teams have never modeled, never monitored and never rehearsed a response to this.”

Goerlich’s advice to CISOs is to require device-bound authenticators, such as hardware tokens or computers, for all privileged and sensitive access. They may consider allowing wallets for lower risk access, he said, “however, much like passwords in Web browsers have long been at risk, we must now consider passkeys in the browsers an unacceptable risk.”

Thousands of Internet-connected servers sold by the world’s biggest manufacturers can be remotely backdoored by exploiting critical vulnerabilities—some more than a decade old—that lurk deep inside system motherboards, according to research presented Wednesday.

Baseboard management controllers are miniature computers that are embedded into the motherboards of virtually every enterprise server. The microcontrollers, typically abbreviated as BMCs, run with their own operating system firmware, network stack, and IP address. Administrators rely on them to monitor the physical status of large fleets of servers and to perform a variety of tasks, including rebooting machines, installing updates, and even reinstalling operating systems. BMCs provide what’s known as “lights out” and “out-of-band” management because they work even when servers they’re attached to are turned off or are unresponsive.

A “pervasive, under-monitored, under-patched parallel attack surface”

Researchers have warned since at least 2013 that BMCs present a golden opportunity for hackers looking for ways to gain deep and persistent access to datacenters. The chief culprit was IPMI, the protocol that allows BMCs to operate independently of servers and to perform administrative tasks. Vulnerabilities in this firmware made it possible for attackers to remotely execute malicious code on the controllers and, from there, infect the servers they manage.
