Elastic Endgame detected an Exploit. Exploit - Prevented - Elastic Endgame. Elastic Endgame prevented an Exploit. Exporting Exchange Mailbox via PowerShell. Adversaries may target user email to collect sensitive information.

Generates a detection alert for each external alert written to the configured indices. Enabling this rule allows you to immediately begin investigating external alerts in the app. Identifies domains commonly used by adversaries for post-exploitation IP lookups. It is common for adversaries to test for Internet access and acquire their external IP address after they have gained access to a system. Among others, this has been observed in campaigns leveraging the information stealer, Trickbot.

File Deletion via Shred. Malware or other files dropped or created on a system by an adversary may leave traces behind as to what was done within a network and how. Adversaries may remove these files over the course of an intrusion to keep their footprint low or remove them at the end as part of the post-intrusion cleanup process. File Permission Modification in Writable Directory. Identifies file permission modifications in common writable directories by a non-root user.

Adversaries often drop files or payloads into a writable directory and change permissions prior to execution. File and Directory Discovery. Enumeration of files and directories using built-in tools.

Adversaries may use the information discovered to plan follow-on activity. Finder Sync Plugin Registered and Enabled. Adversaries may abuse this feature by adding a rogue Finder Plugin to repeatedly execute malicious payloads for persistence. Custom roles are user-defined, and allow for the bundling of one or more supported permissions to meet specific needs. Custom roles will not be updated automatically and could lead to privilege creep if not carefully scrutinized. A role contains a set of permissions that allows you to perform specific actions on Google Cloud resources.

An adversary may delete an IAM role to inhibit access to accounts utilized by legitimate users. If a key is deleted, the application will no longer be able to access Google Cloud resources using that key. A security best practice is to rotate your service account keys regularly. Identifies the creation or patching of potential malicious rolebinding.

You can assign these roles to Kubernetes subjects users, groups, or service accounts with role bindings and cluster role bindings. Log buckets are containers that store and organize log data. A deleted bucket stays in a pending state for 7 days, and Logging continues to route logs to the bucket during that time. To stop routing logs to a deleted bucket, the log sinks can be deleted that have the bucket as a destination, or the filter for the sinks can be modified to stop routing logs to the deleted bucket.

An adversary may delete a log bucket to evade detection. Every time a log entry arrives, Logging compares the log entry to the sinks in that resource. An adversary may delete a Logging sink to evade detection.

Logging compares the log entry to the sinks in that resource. An adversary may update a Logging sink to exfiltrate logs to a different export destination. A subscription is a named resource representing the stream of messages to be delivered to the subscribing application. A topic is used to forward messages from publishers to subscribers. A publisher application creates and sends messages to a topic. A service account is a special type of account used by an application or a virtual machine VM instance, not a person.

Applications use service accounts to make authorized API calls, authorized as either the service account itself, or as G Suite or Cloud Identity users through domain-wide delegation. If service accounts are not tracked and managed properly, they can present a security risk. An adversary may create a new service account to use during their operations in order to avoid using a standard user account and attempt to evade detection.

If private keys are not tracked and managed properly, they can present a security risk. An adversary may create a new key for a service account in order to attempt to abuse the permissions assigned to that account and evade detection. Each VPC network has its own subnets, routes, and firewall, as well as other elements. Google Cloud routes define the paths that network traffic takes from a virtual machine VM instance to other destinations. These destinations can be inside a Google VPC network or outside it.

Detects when a domain-wide delegation of authority is granted to a service account. Domain-wide delegation can be configured to grant third-party and internal applications to access the data of Google Workspace users. Detects when an admin role is assigned to a Google Workspace user. Google Workspace Admin Role Deletion. Detects when a custom admin role is deleted. An adversary may delete a custom admin role in order to impact the permissions or capabilities of system administrators.

Since multi-instancing redirection is not supported for JavaScript applications, the AppInstance class is not useful for such applications. If you are creating a new multi-instance application, you can install the Multi-Instance App Project Templates. Two templates are installed: Multi-Instance UWP app , which provides the template for creating a multi-instance app, and Multi-Instance Redirection UWP app , which provides additional logic that you can build on to either launch a new instance or selectively activate an instance that has already been launched.

For example, perhaps you only want one instance at a time editing the same document, so you bring the instance that has that file open to the foreground rather than launching a new instance.

Both templates add SupportsMultipleInstances to the package. Note the namespace prefix desktop4 and iot2 : only projects that target the desktop, or Internet of Things IoT projects, support multi-instancing. Multi-instancing support for UWP apps goes beyond simply making it possible to launch multiple instances of the app. It allows for customization in cases where you want to select whether a new instance of your app is launched or an instance that is already running is activated.

For example, if the app is launched to edit a file that is already being edited in another instance, you may want to redirect the activation to that instance instead of opening up another instance that that is already editing the file. The logic for redirecting activation goes in the Main function. The Parameters key is missing.

An incorrect proxy server name was specified in the user's Internet Explorer proxy settings. Change the user's Internet Explorer proxy settings to be a valid proxy server. Internet Explorer on the same machine in the context of the job owner would see the same problem. Try downloading the same file via the web browser using the context of the job owner. If the server or proxy server doesn't understand range requests and returns the full file instead of the requested range, BITS puts the job into the ERROR state with this error.

Check proxy servers to ensure that they are configured correctly to support Range requests. Check the proxy server and WSUS server to ensure that they are configured correctly.

Some versions of the Apache 2. Check access permissions for the account running the job. The SENS service isn't receiving user logon notifications. BITS version 2. Ensure that the SENS service is started and running correctly.
