A likely zero-day vulnerability in SonicWall VPNs is being actively exploited to bypass MFA and deploy ransomware. Huntress advises disabling the VPN service immediately or severely restricting access via IP allow-listing. We're seeing threat actors pivot directly to domain controllers within hours of the initial breach.
Le 13 mai 2025, Fortinet a publié un avis de sécurité concernant la vulnérabilité CVE-2025-32756. Celle-ci permet à un attaquant non authentifié d'exécuter du code arbitraire à distance. L'éditeur indique que cette vulnérabilité est activement exploitée. Les exploitations constatées jusqu'ici...
Varonis Threat Labs discovered a vulnerability in Azure SQL Server allowing privileged users to create malicious firewall rules that can delete Azure resources when triggered by admin actions. The exploit involves manipulating rule names via TSQL to inject destructive commands, potentially leading to large-scale data loss in affected Azure accounts.
Fortinet a publié le 10 avril 2025 un billet de blogue [1] indiquant l'utilisation d'une technique de post-exploitation qui permet une atteinte à la confidentialité des données de l'ensemble du système des équipements Fortigate affectés. Cette technique repose sur l'utilisation d'un lien...

Le 8 novembre 2024, Palo Alto Networks a publié un avis de sécurité relatif à une vulnérabilité critique dans certains pare-feux Palo Alto Networks. Elle permet à un attaquant non authentifié d'exécuter du code arbitraire à distance sur l'interface d'administration des équipements. L'éditeur...
**[Mise à jour du 14 janvier 2025]** **Publication des correctifs** Le 14 janvier 2025, Fortinet a publié un avis de sécurité relatif à la vulnérabilité CVE-2024-50566 qui correspond à la vulnérabilité de type jour-zéro pour laquelle une preuve de concept a été publiée en novembre 2024. Des...
The AWS Client VPN service was found to be affected by two vulnerabilities which could potentially allow malicious actors with access to a user’s device to execute arbitrary commands with elevated privileges, including escalating to root access. Both vulnerabilities stem from buffer overflow issues, a common programming error that can be exploited to overwrite memory and gain unauthorized control over a system. The impact of these vulnerabilities is severe, as successful exploitation could lead…
Tenable Research discovered a vulnerability in Azure allowing attackers to bypass firewall rules based on Service Tags by forging requests from trusted services. It affects over 10 Azure services and enables access to internal/private Azure resources. Microsoft updated documentation to clarify Service Tags' security limitations.
A vulnerability in Microsoft Graph allowed attackers to conduct password-spray attacks without detection. The issue involved switching the 'common' authentication endpoint with that of an unrelated tenant, thereby avoiding the appearance of logon attempts in the victim's logs. This technique could allow attackers to validate user credentials through verbose error messages, but actual successful logons using these credentials would still be recorded in the victims' logs (regardless of endpoint).
\[Mise à jour du 10 mai 2024\] Le CERT-FR est intervenu pour le traitement d'une compromission par rançongiciel au sein d'une entité française. Dans le cadre de cette attaque, la vulnérabilité a été exploitée pour ensuite réaliser une latéralisation dans le système d'information de la victime et...
\[Mise à jour du 19 mars 2024\] Le CERT-FR a connaissance de codes d'exploitation publics et de nouvelles tentatives d'exploitation. Le 8 février 2024, Fortinet a publié l'avis de sécurité concernant la vulnérabilité critique CVE-2024-21762 affectant le VPN SSL de FortiOS. Cette vulnérabilité...
Palo Alto discovered that Azure CLI commands were found to leak sensitive credentials and environment variables in GitHub Actions logs. This issue affects both public and private repositories, potentially exposing secrets to unauthorized parties. The problem stems from the Azure CLI's design to echo back accessed/created/updated/deleted resource information, which can include sensitive data. Later research by Orca Security revealed that AWS CLI and Google Cloud CLI were affected by the same iss…
Is it worth switching to Microsoft Defender Antivirus? Spoiler alert: We think yes! Explore why Defender is a solid AV solution.
In Azure Serverless Functions, a new container is generated by the host for every function, which is then terminated and deleted after several minutes. Palo Alto discovered that an API call was available to bind one path to another within the container (called "init_server_pkg_mount_BindMount") that could be called by a low-privileged user but executed with root privileges. This could enable a malicious tenant to escalate their privileges to root, and then escape their container by abusing the …
Dive into the types of threats we’ve thwarted with Managed Antivirus and how IT teams are seeing more value from making the switch.
Executing Cloud Functions or Cloud Run in any project and in any organization allowed bypassing the GKE Authorized Networks (aka Kubernetes control plane firewalls) of a cluster in a different project or organization.
The AWS VPN Client application is affected by an arbitrary file write as SYSTEM, which can lead to privilege escalation and an information disclosure vulnerability that allows the user's Net-NTLMv2 hash to be leaked via a UNC path in a VPN configuration file.
Our partners at United Systems and F1 Solutions talk about their respective journeys with our Managed Microsoft Defender solution.
How do you protect computers from attackers if you’re not familiar with hacking techniques? The historical answer to this question has been antivirus and firewalls. However, the last several years have demonstrated hackers can slip past these preventative technologies and cause devastating results to the victims.
