Fortinet customers are seeing attackers exploiting a patch bypass for a previously fixed critical FortiGate authentication vulnerability (CVE-2025-59718) to hack patched firewalls.
Fortinet customers are seeing attackers exploiting a patch bypass for a previously fixed critical FortiGate authentication vulnerability (CVE-2025-59718) to hack patched firewalls.
One of the affected admins said that Fortinet has allegedly confirmed that the latest FortiOS version (7.4.10) didn't fully address this authentication bypass vulnerability, which should've been patched in early December with the release of FortiOS 7.4.9.
Fortinet is also reportedly planning to release FortiOS 7.4.11, 7.6.6, and 8.0.0 over the coming days to fully patch the security flaw.
"We just had a malicious SSO login on one of our FortiGate's running on 7.4.9 (FGT60F). We have a SIEM that caught the local admin account being created. Now, I have done a little research, and it appears this is exactly how it looked when someone came in on CVE-2025-59718. But we have been on 7.4.9 since December 30th," the admin said.
The customer shared logs showing that the admin user was created from an SSO login of cloud-init@mail.io from IP address 104.28.244.114. These logs looked similar to previous exploitation of CVE-2025-59718 seen by cybersecurity company Arctic Wolf in December 2025, which reported that attackers were actively exploiting the vulnerability via maliciously crafted SAML messages to compromise admin accounts.
"We observed the same activity. Also running 7.4.9. Same user login and IP address. Created a new system admin user named "helpdesk". We have an open ticket with support. Update: The Fortinet developer team has confirmed the vulnerability persists or is not fixed in v7.4.10," another one added.
BleepingComputer reached out to Fortinet multiple times this week with questions about these reports, but the company has yet to reply.
Until Fortinet provides a fully patched FortiOS release, admins are advised to temporarily disable the vulnerable FortiCloud login feature (if enabled) to secure their systems against attacks.
To disable FortiCloud login, you have to navigate to System -> Settings and switch "Allow administrative login using FortiCloud SSO" to Off. However, you can also run the following commands from the command-line interface:
config system global
set admin-forticloud-sso-login disable
end
Luckily, as Fortinet explains in its original advisory, the FortiCloud single sign-on (SSO) feature targeted in the attacks is not enabled by default when the device is not FortiCare-registered, which should reduce the total number of vulnerable devices.
However, Shadowserver still found over 25,000 Fortinet devices exposed online with FortiCloud SSO enabled in mid-December. At the moment, more than half have been secured, with Shadowserver now tracking just over 11,000 that are still reachable over the Internet.
CISA has also added the CVE-2025-59718 FortiCloud SSO auth bypass flaw to its list of actively exploited vulnerabilities, ordering federal agencies to patch within a week.
Hackers are now also actively exploiting a critical Fortinet FortiSIEM vulnerability with publicly available proof-of-concept exploit code that can enable them to gain code execution with root privileges on unpatched devices.
RSAC: Can we turn to govt, academic models instead?
Corporate AI models are already skewed to serve their makers' interests, and unless governments and academia step up to build transparent alternatives, the tech risks becoming just another tool for commercial manipulation.
That's according to cryptography and privacy guru Bruce Schneier, who spoke to The Register last week following a keynote speech at the RSA Conference in San Francisco.
"I worry that it'll be like search engines, which you use as if they are neutral third parties but are actually trying to manipulate you. They try to kind of get you to visit the websites of the advertisers," he told us. "It's integrity that we really need to think about, integrity as a security property and how it works with AI."
During his RSA keynote, Schneier asked: "Did your chatbot recommend a particular airline or hotel because it's the best deal for you, or because the AI company got a kickback from those companies?"
To deal with this quandary, Schneier proposes that governments should start taking a more hands-on stance in regulating AI, forcing model developers to be more open about the information they receive, and how the decisions models make are conceived.
He praised the EU AI Act, noting that it provides a mechanism to adapt the law as technology evolves, though he acknowledged there are teething problems. The legislation, which entered into force in August 2024, introduces phased requirements based on the risk level of AI systems. Companies deploying high-risk AI must maintain technical documentation, conduct risk assessments, and ensure transparency around how their models are built and how decisions are made.
Because the EU is the world's largest trading bloc, the law is expected to have a significant impact on any company wanting to do business there, he opined. This could push other regions toward similar regulation, though he added that in the US, meaningful legislative movement remains unlikely under the current administration.
Google intelligence report finds UK is a particular target of IT worker ploy that sends wages to Kim Jong Un’s state
British companies are being urged to carry out job interviews for IT workers on video or in person to head off the threat of giving jobs to fake North Korean employees.
The warning was made after analysts said that the UK had become a prime target for hoax IT workers deployed by the Democratic People’s Republic of Korea. They are typically hired to work remotely, enabling them to escape detection and send their wages to Kim Jong-un’s state.
Google said in a report this month that a case uncovered last year involved a single North Korean worker deploying at least 12 personae across Europe and the US. The IT worker was seeking jobs within the defence industry and government sectors. Under a new tactic, the bogus IT professionals have been threatening to release sensitive company data after being fired.
The Federal Bureau of Investigation (FBI) warns the public about an ongoing fraud scheme where criminal scammers are impersonating FBI Internet Crime Complaint Center (IC3) employees to deceive and defraud individuals. Between December 2023 and February 2025, the FBI received more than 100 reports of IC3 impersonation scams.
MITRE Vice President Yosry Barsoum has warned that U.S. government funding for the Common Vulnerabilities and Exposures (CVE) and Common Weakness Enumeration (CWE) programs expires today, which could lead to widespread disruption across the global cybersecurity industry.
Two spyware variants – Moonshine and BadBazaar – are being used to target the mobile devices of persons of interest to Chinese intelligence, including individuals in the Taiwanese, Tibetan and Uyghur communities.
The FBI is warning the public that criminals exploit generative artificial intelligence (AI) to commit fraud on a larger scale which increases the believability of their schemes. Generative AI reduces the time and effort criminals must expend to deceive their targets. Generative AI takes what it has learned from examples input by a user and synthesizes something entirely new based on that information. These tools assist with content creation and can correct for human errors that might otherwise serve as warning signs of fraud. The creation or distribution of synthetic content is not inherently illegal; however, synthetic content can be used to facilitate crimes, such as fraud and extortion.1 Since it can be difficult to identify when content is AI-generated, the FBI is providing the following examples of how criminals may use generative AI in their fraud schemes to increase public recognition and scrutiny.

Okta warns of an "unprecedented" spike in credential stuffing attacks targeting its identity and access management solutions, with some customer accounts breached in the attacks.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) revealed today that attackers who hack Ivanti VPN appliances using one of multiple actively exploited vulnerabilities may be able to maintain root persistence even after performing factory resets.
Based upon the authoring organizations’ observations during incident response activities and available industry reporting, as supplemented by CISA’s research findings, the authoring organizations recommend that the safest course of action for network defenders is to assume a sophisticated threat actor may deploy rootkit level persistence on a device that has been reset and lay dormant for an arbitrary amount of time. For example, as outlined in PRC State-Sponsored Actors Compromise and Maintain Persistent Access to U.S. Critical Infrastructure), sophisticated actors may remain silent on compromised networks for long periods. The authoring organizations strongly urge all organizations to consider the significant risk of adversary access to, and persistence on, Ivanti Connect Secure and Ivanti Policy Secure gateways when determining whether to continue operating these devices in an enterprise environment.
Today, Ivanti warned of a new authentication bypass vulnerability impacting Connect Secure, Policy Secure, and ZTA gateways, urging admins to secure their appliances immediately.
