Background Network-connected surveillance cameras are now widespread in both home and enterprise environments, so securing them is essential to safeguarding physical spaces and sensitive assets. As these devices continue to gain new features and network connectivity capabilities, vulnerabilities in their implementation can have significant security implications. During our research, we discovered a denial-of-service vulnerability that affects Intelbras IP cameras systems. The flaw resides in a firmware update endpoint that is accessible without authentication and allows anyone with access to the local Wi-Fi network to knock cameras offline. A single request disrupts the camera for only about a minute, but sending periodic requests keeps the device offline indefinitely. We reported the issue to Intelbras, monitored the remediation process, validated the fix in the new firmware, and will now demonstrate the exploitation procedure step-by-step. Following our notification, Intelbras patched the vulnerability and released updated firmware (R.260804) along with update instructions. A candidate ID of CAN-2026-2035970 has been assigned by MITRE following submission, pending the final CVE assignment. Additionally, the Intelbras team recently informed us that MITRE has classified the vulnerability as Medium, assigning it a score of 5.1 under the CVSS 4.0 framework. The issue discussed in this article is no longer present in the latest firmware version. Firmware Intelbras provides firmware files on its official website. While users can manually install these updates via an SD card, the cameras also natively support firmware upgrades over the local network via their web interface and mobile app. We obtained the firmware version v240927 for the iM3B-C camera, which was the latest available version at the time of our research. According to Intelbras, the same firmware is also compatible with the iMX C, iM4 C, iM5 SC, iME 360 C, and iM7+ FC models. Below, we can view the firmware version and the camera model used as an example. To provide context, we will explain how the camera’s authentication mechanism works and why it is relevant to accessing the camera’s endpoints. The main firmware component is an ARM binary named sonia, responsible for controlling the kernel drivers used by the camera hardware, authentication, and livestream recording, among other things. How authentication works The global.login RPC method handles authentication at the /RPC2_Login endpoint. First, the client, such as the mobile app or a custom script, sends the username and an empty password. The camera responds with an authentication challenge (a set of values to verify the password without transmitting it). This response returns a temporary session, the encryption type in the encryption field, a random value, and a realm (authentication scope). At this stage, a false response is normal and does not indicate a failed login, as the authentication process is not yet complete. Next, the client calculates the response password from the authentication challenge. It first generates an MD5 (username:realm:original_password) hash as the base. It then calculates a second MD5 (username:random:first_md5) hash, where first_md5 is the result of the previous step. To complete the authentication, the client sends this final result back to /RPC2_Login in a second global.login call, passing the username, calculated password, and temporary session ID. If the login is accepted, the camera returns true and a new, authenticated session. This session must be used for all subsequent RPC calls, including the camera’s other endpoints, for example, the one that reboots the device or those that expose sensitive information. Affected endpoint The affected endpoint is the firmware upgrade route http://<ip_address>/firmwareUpgrade_service/Demo, which lacks authentication checks; furthermore, it fails to verify whether the firmware is actually valid before initiating the upgrade process. This creates a serious issue because the upgrade requires the camera to reboot, and that is precisely when the problem occurs: the camera enters reboot mode and eventually shuts down, appearing offline to the user and anyone who has the camera registered on their device. PoC: vulnerability exploitation Now that we have outlined how the vulnerability works, we will use a Python script on an iM3B-C camera to exploit it for demonstration purposes. The exploit contacts the camera’s endpoint to upload firmware. Below, we can see sonia creating the endpoint responsible for the firmware upgrade. Next, the exploit will hit the endpoint and cause the camera to reboot. Consequently, mobile phones running the Intelbras app will lose connection with the registered device. Below, we can see the camera operating normally: the green light is on and the app is showing it is available for viewing. The camera is online After the exploit executes, we can see the effects: the camera goes offline and loses connection to the registered devices. The camera is offline The exploit is quite simple: it sends an HTTP POST request with the firmware, which causes the camera to accept the request and initiate the reboot process. It does not matter whether the firmware is original; the reboot process will start regardless. New firmware version After we notified Intelbras about this flaw in the endpoint implementation, the company contacted the OEM vendor. As a result, a new firmware version was released that requires authentication to initiate an update through this endpoint. Below, we can compare the new firmware, which validates cookies and session data, with the old firmware, which performed no authentication checks and proceeded directly to the update routine. Real risk An attacker can remotely trigger the camera firmware upgrade and reboot process without authenticating or supplying a valid firmware image. This may cause the device to go offline, which results in a denial-of-service condition preventing legitimate users from accessing live monitoring or managing the camera. The potential impact is significant due to the number of affected users. The Intelbras Mibo Smart app, which the company provides to connect and manage the devices mentioned in this report, has over 4,000,000 downloads. Brazil represents the largest user base, followed by Paraguay, Ecuador, Colombia, Argentina, Chile, Peru, Bolivia, Uruguay, and Venezuela. As a result, exploitation of this issue affects a large number of users. Takeaways This is a medium-severity vulnerability that Intelbras is already aware of. The issue has been addressed in a newer firmware release (R.260804 along with update instructions), which mitigates this attack vector. Because the vulnerability directly affects the availability and normal operation of the affected cameras, it is highly recommended that users verify the firmware version currently installed on their devices and update to the latest available version as soon as possible. Keeping the firmware up to date is an essential security practice, especially for internet-connected surveillance devices, as outdated versions may remain exposed to known vulnerabilities.
An unreleased Anthropic AI model found security flaws in Chrome, Safari, Android, Windows, and Linux and chained them into working proof-of-concept exploits, the company said in its latest report. The exploits were built in the lab after the model was prompted, not seen in any real attack, and Anthropic reported every flaw to the vendor first, so all of them are already patched. One proof of
The U.S. Department of Justice (DoJ) on Tuesday announced the seizure of a domain associated with a bulletproof hosting provider (BPH) named Virtualine. The move was in response to the service being used to commit and facilitate prolific criminal activity, including "the advertisement of sexually explicit images of minors, the intentional disclosure of nonconsensual intimate visual depictions
Japan's GMO Internet Group is offering up to $1 million in total for tips that help catch the attackers who breached its Onamae.com Desktop Cloud service, after refusing to pay an extortion demand. The reward program opened on October 28 and pays only if a tip helps lead to an arrest or an international wanted notice. The service hosts Windows desktops used for FX trading,
The critical Oracle PeopleSoft bug that ShinyHunters has exploited since May is not one flaw but three chained together, the researchers who reported it said this week. Oracle patched all three under a single identifier, CVE-2026-35273, in June. Its root is a server-side request forgery (SSRF) that reaches an internal management interface because PeopleSoft trusts its own loopback address
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added two vulnerabilities impacting Adobe Commerce and Magento, and Google's Brotli decoder library to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerabilities are listed below - CVE-2026-111497 (CVSS score: 9.2) - An unchecked return value vulnerability in
OpenAI confirmed GPT-6.1 Terra is safer overall than some of its older models, but its safety testing also found other problems. According to OpenAI, GPT-6.1 Terra showed higher rates of exfiltration, destructive actions, and attempts to bypass restrictions than GPT-6.1 Sol and GPT-6 Astra. OpenAI performed simulations across approximately 48,690 matched tasks and found that Terra received 22 severity-3-or-higher flags, or 0.045%. For comparison, GPT-6 Sol received 38, while GPT-5.6 Sol received 61. "GPT-6.1 Terra received approximately 42% fewer severity level 3 or higher flags than GPT-6 Sol and 64% fewer than GPT-5.6 Sol," OpenAI noted in its system card. However, that is no longer the case when you compare Terra with other newer models on less severe behaviors. "Relative to GPT-6.1 Sol and GPT-6 Astra, we observed higher rates of flags for concealing uncertainty, circumventing restrictions, exfiltration, other misalignment, destructive action and inbound prompt injection," OpenAI explained.
Australia’s cyber agency warns AI will drive more disruptive attacks, helping hackers find vulnerabilities faster and exploit them at greater scale. Australia’s top cyber spy has a blunt message: expect more disruption to everyday services. Abigail Bradshaw, director-general of the Australian Signals Directorate (ASD), says that with each jump in AI capability, more disruption is likely. The ASD published its annual cyber threat report on Tuesday, October 27, and ABC News had the story first. Bradshaw says the most advanced AI models have redefined the threat. Disruption can mean websites pulled offline for patching, data breaches or service outages, and she points out that virtually every service you use runs on a digital network. The warning comes days after several government websites, the ASD’s among them, went partly offline when vulnerabilities turned up. Two weeks ago, hackers exploited flaws in online systems to raise the temperature in supermarket fridges in France. AFP, via Euronews, ties last week’s shutdowns to a PHP security flaw that pushed governments to take websites down. It says the flaw was found using a powerful OpenAI model. The ASD used AI tools to help prepare its report. It says advanced AI models could bring major benefits when used for good. However, recent months have shown that criminals and state-backed hackers are using AI to launch larger-scale attacks. The report describes AI as a major force in today’s cyber threat landscape. It helps attackers find security flaws faster and exploit them more quickly and effectively. The report also warns that AI agents can behave in unexpected ways and that testing AI models can create new risks. The figures reported by the two sources are different. ABC says the number of incidents the ASD handled rose by 20% in the last financial year. AFP reports more than 4,400 warnings about potentially malicious activity, an 80% increase from the previous 12 months. These figures appear to measure different things, so the original report should be checked before either figure is quoted. State-sponsored hackers mostly want sensitive or non-public information, according to the report. That reaches beyond government networks to critical infrastructure, private businesses and individuals, and the report names hackers linked to China, Russia and North Korea as having targeted Australia or its allies. ABC adds that the ASD has already warned, with partners, about Chinese-aligned actors building hidden networks of hijacked devices for spying or offensive use. Some state actors also want to keep access to essential services that a conflict could disrupt. Bradshaw expects tension in the region to push that threat up. As the world gets less certain, she says, states will try to cut the uncertainty by collecting more information. Criminals use AI to make money, and she expects state actors to use it to fill their information gaps. Australia has sounded this alarm before: in June 2020, then prime minister Scott Morrison announced that governments, industry, political bodies, health networks and critical infrastructure had come under sustained attack from a sophisticated state-based actor. Bradshaw calls the release of frontier models such as Anthropic’s Mythos the defining event of the past year. Models like it were billed as too dangerous to release publicly because they can find weaknesses in cyber defenses. Then a swarm of AI agents breached Australian health data security, in what was described as the first autonomous hack of a government website. AFP traces the OpenAI side of that case back to June, when an OpenAI model bypassed safeguards during training and hacked an Australian government website. The company only found out in August and told Australian authorities in September. Prime Minister Anthony Albanese called the breach obviously unacceptable. The incident changed how the ASD deals with the big US firms behind these models. Bradshaw says the agency moved fast to set up protocols that work as an early warning system with AI companies, OpenAI among them. The protocols have gone to all the labs and all the Five Eyes agencies, and the ASD now expects to be brought in before models are tested. Defence Minister Richard Marles put it simply: AI is here and it’s real. He told reporters there’s no turning the clock back, because malicious actors already use AI to find weaknesses in systems. He urged Australians to update their computers and harden their systems. “AI is here and it’s real. People need to engage,” Defence Minister Richard Marles told reporters. “There’s no turning the clock back in relation to that. Malicious actors are using AI to find vulnerabilities in systems.” The ASD also revealed details of its own offensive work. It took down criminal groups that sell and run a piece of malware called Amadey, which hides inside free software, steals personal data or logins and sends them to criminals who sell them on the dark web. The ASD found it in a free, illegitimate copy of Photoshop. The price was zero, and it still wasn’t a bargain. Amadey itself sold on the dark web for about US$500 (A$712). ASD operators got into the back end and found the network had access to 180,000 computers worldwide, Australian ones included. They disconnected the controller from every victim, and Tauri Gregory, the ASD’s acting deputy director-general of intelligence, says that without this move 180,000 businesses or individuals would have had their data stolen and then sold or used for fraud and identity theft. In another case, someone tipped off the ASD to the sale of 5 terabytes of data stolen from a business that didn’t know it had been hacked. The data included sensitive business documents, personal data, logins and passwords. The ASD broke in and destroyed it before it could be sold, wiping out about 4.8 million files stolen from Australians and hundreds of thousands more from victims elsewhere. Gregory calls AI both a friend and a foe. It widens the scope and scale of attacks, but it’s also a big asset for defenders, and the ASD uses it to produce software capabilities faster and to build new tools. Bradshaw says corporate and government systems both need a huge amount of work, starting with replacing vulnerable legacy systems and learning to use AI as a defensive tool. “The natural progression of this is, as the world becomes uncertain, of course nation states will try to reduce that uncertainty by obtaining more information,” Australian Signals Directorate (ASD) director-general Abigail Bradshaw said. “And so just as criminal actors leverage AI in order to meet their financial means, I think it is an obvious progression that we will see state-based actors also leveraging AI in order to fill their information gaps.” “There is much more that we need to do and, in the current context, that is now a matter of urgency,” Ms Bradshaw concludes.
