The French-speaking gang managed to carry out over 30 successful attacks on banks, financial services and telecommunications companies, mainly located in Africa.
Cosmos DB notebooks lacked an authentication check, meaning that if an attacker somehow had prior knowledge of a notebook’s temporary ‘forwardingId’ (a 128bit cryptographically random GUID assigned to a short-lived workspace that expires after an hour), they could gain full permissions on the notebook, including read and write access and the ability to modify the file system of the container running the notebook. These permissions would suffice for an attacker to obtain remote code execution (R…
We're excited to announce the general availability of the Huntress macOS agent! And don't worry – Persistent Footholds are just the beginning.
Huntress has validated an initial report for an authentication bypass and sensitive file leak present in the Java framework “ZK”, used within the ConnectWise R1Soft software Server Backup Manager SE.
We’ve been seeing some misinformation being spread around with regards to the Huntress technology stack/capabilities we possess today. We’re here to provide clarity.
Azure CLI contained a code injection vulnerability that could be exploited in a scenario where the host runs a command where parameter values have been provided by an external untrusted source - these could be specially crafted in such a way as to exploit the vulnerability, leading to remote code execution on the host. The vulnerability is only applicable when the Azure CLI command is run on a Windows machine and with any version of PowerShell and when the parameter value contains the `&` or `|…

Analysis of months-long MajikPOS and Treasure Hunter campaign that infected dozens of terminals
A vulnerability in the GitHub Actions Runner allowed untrusted inputs in environment variables to escape and modify docker command invocations. This affected jobs using container actions, job containers, or service containers. The issue has been patched in multiple versions of the runner.
The Group-IB Incident Response Team investigated an incident related to a DeadBolt attack and analyzed a DeadBolt ransomware sample
In September 22', SOCRadar discovered an insecure public Azure blob storage owned by Microsoft (olyympusv2.blob.core.windows[.]net). This blob storage was used for storing emails and other documents from interactions with their customers (such as contracts and purchase orders). In total, the blob storage contained 2.4TB of data with information concerning thousands of Microsoft customers across dozens of countries, dated between 2017 and August 22'. Following disclosure, Microsoft reconfigured …
We’ve got a problem in cybersecurity that needs to be addressed—and it has to do with accessibility to women.

Service Fabric Explorer (SFX) is a tool for inspecting and managing Azure Service Fabric clusters. An attacker with existing access to a "Deployer" type user with CreateComposeDeployment permissions in a given cluster could create a malicious application with a specially-crafted name. This would lead to client-side template injection (CSTI) and storing a malicious XSS payload in a dashboard shared between users of the same cluster. If a victim user with administrative permissions logged into th…
Azure Arc allows customers to connect on-premises Kubernetes clusters to Azure. This is facilitated by middleware (the Azure Arc-enabled Kubernetes agent) which includes a "cluster connect" feature in the form of a reverse proxy. A vulnerability in this feature could allow an unauthenticated user to elevate their privileges and potentially gain remote administrative control over any Azure Arc-enabled cluster, as long as they know its randomly generated external DNS endpoint. Azure Stack Edge de…

Bug bounty programs are everywhere for enterprise organizations. But where does that leave the 99%—those under-resourced small to mid-sized businesses?
Any unattached storage volume, or attached storage volumes allowing multi-attachment, could have been read from or written to as long as an attacker knew their Oracle Cloud Identifier (OCID), allowing sensitive data to be exfiltrated or even more impactful attacks to be initiated via executable file manipulation in the target tenant's environment.
An issue in Azure Cloud Shell could have allowed an attacker to take over an Azure App Service domain and leverage it to inject and execute commands in other tenants' terminals if they navigated to the domain while logged into their account. Using this method, an attacker could query the Azure IMDS on other tenants' behalf and thereby obtain their access tokens.
Protecting your servers just isn’t enough to keep bad actors out. Protecting the workstation is often an overlooked but critical step to security.

Azure Synapse Analytics is an analytics service for processing data using various runtimes, among them Apache Spark. Synapse provided users the capability to mount Azure File Shares to their Apache Spark Pools via a script called filesharemount.sh that would execute with elevated privileges. This script would mount the File Share to the /synfs directory. There was a race condition in the script where, if successfully exploited, a user could execute the chown command to change the ownership of a…

Amazon SNS' signature validation in the official SDK relied on a weak regex for default AWS certificate locations, that would incorrectly match an S3 bucket named `sns`. This bucket happened to be publicly readable and writeable, allowing an attacker to forge messages to any user of the official SDK SNS validator.
