This category also covers locations on a system or network where the adversary may look for information to exfiltrate. Machine logs indicate that a suspicious request was made to the Kubernetes Dashboard. SELECT * FROM c WHERE c.ZipCodes[0].Code IN ("6500", "6700") and using UDF will actually result on the query not using the index. This paves an easy path for you to build many different solutions for many different scenarios. This behavior was seen [x] times today on the following machines: [Machine names]. Microsoft Defender for Servers Plan 2 provides unique detections and alerts, in addition to the ones provided by Microsoft Defender for Endpoint. Azure Cosmos DB is rapidly growing in popularity, and for good reason. Such activity, while possibly legitimate user behavior, is frequently performed by attackers to evade network monitoring and filtering. Such exclusion practically disabling the Antimalware protection. During the recent Ignite conference, Microsoft announced Azure Cosmos DB for PostgreSQL, a new generally available (GA) service to build cloud-native relational applications. We can try and solve this. These are used to get a compromised machine to call back into a machine an attacker owns. Like. Machine logs indicate that your Docker daemon (dockerd) exposes a TCP socket. This can indicate that the account is compromised and is being used with malicious intent. Adopt the right emerging trends to solve your complex engineering challenges. Azure Cosmos DB goven - A drop-in query language for any database schema. Hot partition key.

If you want to run a query that includes data from other accounts or data from other Azure services, select Logs from the Azure Monitor menu. Here is an example of an SQL query for creating a database, entering into it, and then create a table. A SPARQL endpoint accepts queries and returns results via HTTP.. Generic endpoints will query any Web-accessible RDF data; Specific endpoints are hardwired to query against particular datasets; The results of SPARQL queries A query like, GetCurrentDateTime/GetCurrentTimestamp/GetCurrentTicks, Calculate the current time before query execution and use that string value in the. For instance, an e-commerce website with a large-scale order processing pipeline. Other metrics not in this list might be available in the portal or through legacy APIs. Follow the performance tips, and use a single CosmosClient instance across an entire process. To make this work, the CFP library persists a set of leases as documents in another dedicated Azure Cosmos DB container. Create multiple client instances. We recommend further investigations. This was detected by analyzing Azure Resource Manager operations in your subscription. Store the query result in a real-time materialized view, Optimizations that reduce the Request Unit (RU) charge of the query. Fairware ransomware is known to execute rm -rf commands in this folder. MicroBurst's exploitation toolkit was used to extract keys from your Azure key vaults. A potential brute force attack has been detected on your resource.

A suspicious SQL statement was used to query a container in this Azure Cosmos DB account. Machine logs indicate a suspicious event log clearing operation by user: '%{user name}' in Machine: '%{CompromisedEntity}'. For example, if a matching document has 10 items in each of the three arrays, it will expand to 1 x 10 x 10 x 10 (that is, 1,000) tuples. This anomalous access pattern may be legitimate activity, but it could be an indication that a threat actor has gained access to the key vault in an attempt to access the secrets contained within it. Using dot notation, you can specify query conditions. Typical related attacker activity is likely to include the download and execution of malicious software or remote administration tools. This was detected by analyzing Azure Resource Manager operations in your subscription. Azure Cosmos DB distributes the overall provisioned throughput evenly across physical partitions. In addition, the product team behind Cosmos DB tweeted: We are offering multiple relational DB options for our users across a number of Database services.

Lets take a closer look at this PaaS offering and how you can benefit from it.
Follow the performance tips, and use a single CosmosClient instance across an entire process. Analysis of host data indicates the use of a DNS call over HTTPS in an uncommon fashion. Then if it finds new items it will consume them as the code you wrote reads them off the Change Feed. We have employed highly qualified writers. This behavior was seen [x] times today on the following machines: [Machine names]. You can communicate with the Azure Cosmos DB for Apache Cassandra through the Cassandra Query Language (CQL) Binary Protocol v4 wire protocol compliant open-source Cassandra client drivers.. By using the Azure Cosmos DB for As a means of achieving business agility, value stream management falls short, and ends up being not very different from what organizations have done for a long time: using program management practices to coordinate work across different teams in a large organization. Analysis of processes running within a container or directly on a Kubernetes node, has detected a suspicious timestamp modification. This is often associated with the MITRE 54ndc47 agent which could be used maliciously to attack other machines. Typical related attacker activity is likely to include the exploitation of any credentials on the legitimate service. While this activity can be legitimate, if attackers have permissions to modify the configmap, they can change the behavior of the clusters DNS server and poison it. APPLIES TO: Thank you again for sharing! The listed permissions for the assigned roles are uncommon to the specific service account. Log queries will only include data from that resource. Indicates that there was a change in the access pattern to an Azure Storage account. Kubernetes audit log analysis detected API requests to your cluster from an IP address that is associated with proxy services, such as TOR. Filtering out Data It allows you to manage your data even if you keep them in data centers that are scattered throughout the world. Lock screen ransomware displays a full-screen message preventing interactive use of the host and access to its files. Analysis of host data on %{Compromised Host} detected creation or execution of a process which has previously indicated post-compromise action taken on a victim host by activity group BARIUM. The desired paths specified in the index policy should match the properties in the JSON documents. A round-up of last weeks content on InfoQ sent out every Tuesday. But with NoSQL, we often deliberately duplicate data in order to avoid expensive additional lookups. Such activity, while possibly benign, is frequently performed by attackers to harvest credentials to remote services.

Analysis of host data has detected a successful brute force attack. The volume that was detected is a hostPath type which mounts a sensitive file or folder from the node to the container. If the source IP address is trusted, you can safely suppress this alert for this resource. While this behavior can be legitimate, it's often seen in malicious activities, when attackers try to hide their source IP. This extension may trick users into thinking files are safe to be opened and might indicate the presence of malware on the system. This activity group has been known to use this technique to download additional malware to a compromised host after an attachment in a phishing doc has been opened. The operation was performed by the specified user account. The kubeconfig file, normally used by the Kubelet process, contains credentials to the Kubernetes cluster API server.
