Azure Cognitive Search (ACS) is a full-text search engine service. A new non-default feature allowed for a network control to bypassed, permitting an attacker to submit search queries to any other tenant's network-isolated ACS instance. However, abusing this required a valid API key to access the data plane of the target, along with a number of pieces of information about the target environment (such as the subscription ID and the name of the index to query).

In this blog, we’re going to focus on how Shodan helps us unveil some of the infrastructure that supports ransomware actors.
8 online scams to protect your customers from
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 …
Our team has been tracking conversations surrounding ConnectWise Control vulnerabilities and alleged exploitation. We politely disagree with the threat and criticality presented by the security researcher.
A vulnerability in Elastic Container Registry (ECR) Public could have allowed a malicious actor to delete, update, or create ECR Public images, layers, or tags in registries and repositories belonging to any other AWS account, by abusing undocumented API calls. A malicious actor could have exploited this to delete any or all images in the Amazon ECR Public Gallery or update the content of any existing image to inject malicious code on any machine that would pull and run it.
Our partners at Clear Guidance Partners experienced the value of our EDR capabilities in real-time, pitting them against an active ransomware attack.
In the last blog of our defense evasion series, we'll cover granular advice for monitoring and detecting defense evasion.
IBM Cloud Databases for PostgreSQL was vulnerable to an attack sequence comprised of PostgreSQL privilege escalation via SQL Injection and chaining of three secrets scattered in the service environment (a K8s service account token, a private container registry password, and CI/CD server credentials), which were abusable due to overly permissive network access to internal build servers. A malicious actor could have exploited this vulnerability to remotely execute code in other customers’ environ…
Incident response is a lot like a choose your own adventure exercise. We cover the ground rules and talk about some incidents we’ve helped partners with.
A money mule is someone who moves stolen funds across bank accounts on behalf of cybercriminals. Learn how money mules operate and how you can proactively counteract mule accounts.
We're seeing a rise in Qakbot activity. Here's what you need to know to keep your environments safe.
The AWS AppSync service could be coerced to assume arbitrary roles in other customers' accounts which trusted the AppSync service. This was due to insufficient validation of a serviceRoleArn parameter (caused by a case-sensitivity parsing issue). With this vulnerability, if an adversary knew the ARN of the role associated with AppSync in the target account, they could use it invoke arbitrary AWS API calls.
hack_it 2022 was jam-packed with hacker tradecraft, shady shenanigans, and—as always—a little spice. Check out our favorite moments and highlights!

Group-IB uncovers one thousand (and one) fake domains part of a scam campaign targeting users in KSA
With the beta release of the Huntress macOS agent, we wanted to share some of the Apple-y stuff we’ve been up to behind the scenes.
Binary Security discovered and registered two dangling cloudapp.azure.com subdomains corresponding to subdomains at visualstudio.com. Had these been discovered and registered by an attacker, this would have been equivalent to a 1-click vulnerability for Azure DevOps: the attacker could have crafted a URL referring to the sign-in API for Azure DevOps Services (app.vssps.visualstudio.com) using one of the two subdomains in the "reply_to" field (since subdomains of visualstudio.com would be allowe…
En 2019, l'équipe Threat Intelligence de Group-IB a détecté une série d'attaques ciblant des organisations financières en Afrique.
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 `|…
