The present application relates to the technical field of malware detection, in particular to a malicious code detection method based on behavior analysis, comprising the following steps: monitoring system event flow and process resource occupation data, using fixed time interval sampling to capture network packet arrival time interval, CPU occupation rate fluctuation, target file lock contention state and mouse cursor pixel position, calculating mutual information entropy between different event flows, and revealing hidden associations that cannot be perceived by traditional detection methods. This method is no longer limited to analyzing the isolated behavior of a single process, but captures the weak signals generated when malicious software uses hidden channels for communication or data leakage by quantifying the statistical dependence between seemingly unrelated events.

Embodiments of the present disclosure relate to a method, apparatus, electronic device and computer program product for file lock. In the method, a file lock is imposed on a target file in a first storage device in a storage cluster via a first locking link. The first locking link is associated with the first storage device. If the file lock is not released and the first locking link is failed, a second locking link capable of imposing the file lock on the target file is determined, and the file lock is imposed on the target file via the second locking link. The second locking link is associated with a second storage device in the storage cluster. The method can quickly recover the file lock on the target file in the storage device in scenarios such as partial network failure or IP floating across a three-layer network, and reduce the possibility of read-write errors on the target file.

The application provides a file uploading completion judgment method and a terminal. The method comprises the following steps: in response to a file system event of a target file, starting a monitoring task for the target file; in the monitoring task, acquiring a size attribute of the target file according to a preset sampling period; comparing a first size attribute acquired currently with a second size attribute acquired historically, and updating a stability count according to a comparison result; and when the stability count reaches a preset stability threshold, modifying a write state of the target file to completed. The application realizes accurate identification of an uploading completion opportunity through the size stability detection of a continuous time window without relying on a client behavior or a file lock, and improves robustness by avoiding task suspension through built-in timeout protection.

In some embodiments, a troubleshooting module executes on a host machine alongside an instance of a robotic process automation (RPA) robot that carries out an automation workflow. The troubleshooting module is configured to detect an automation failure and in response, to carry out a forensic investigation to determine a cause of the malfunction. Exemplary causes detected by the troubleshooter include focus theft and an inadvertent file lock. The troubleshooting module is further configured to identify a culprit (i.e., software entity causing the respective failure) and to communicate a descriptor of the culprit to a user, for instance by way of a failure notification displayed on a screen of the respective host machine or within an administration interface exposed by an RPA conductor orchestrating the execution of multiple RPA robots.

This invention discloses a method, apparatus, and storage medium for managing electronic project documentation in investment banking. First, it manages the project documentation directory template based on configurable and version management; then, it binds each stage of the project documentation directory; next, it maintains or rebuilds the project documentation directory; it stores project documentation files; it locks the project documentation directory; and finally, it submits the project documentation for verification. This invention not only enables standardized and customized flexible changes to the project documentation directory but also effectively assists in controlling the correctness and integrity of the project execution process. The coordinated operation of directory locking, documentation storage, and documentation submission effectively controls the execution process, ensuring its correctness and integrity. This invention guarantees the flexibility of investment banking project documentation to adapt to internal and external changes and the standardization of documentation file maintenance, thereby improving the efficiency of investment banking operations and the ability to control risks.

The invention provides a multi-level concurrency control method and system based on a file lock and a state file. The method comprises the following steps: traversing a directory of a data file to be processed; creating a table-level lock file corresponding to the target source data file; the processing node obtains the exclusive processing right of the target source data file and stores the state file set in a directory where the target source data file is located; whether abnormity exists in the state file set or not is judged, if yes, it is judged that the target source data file does not need to be processed so as to release the corresponding table-level lock file, and local isolation is conducted on a source data text file corresponding to the table-level lock file; and all the processing nodes identify the processed files or the local isolation files according to the state files existing in the catalog where each target source data file is located. The method can prevent the single file problem from affecting the overall task execution, multiple nodes can work cooperatively through the shared file system, and the method is easy to integrate with an existing big data ecosystem.

This application discloses a file lock management method, apparatus, electronic device, and storage medium, relating to the field of computer technology. Through this application, the lock granularity of the target file can be dynamically determined and adaptively adjusted based on the client's file access characteristics, and the lock granularity can be optimized in real time based on lock conflict information. Simultaneously, the consistency of lock states among multiple file servers in a distributed environment is maintained. Therefore, it can solve the problem of long recovery time and high network resource consumption caused by existing CIFS file lock methods relying on full scans and retransmissions to restore lock states after server failures. This significantly improves the recovery efficiency of distributed file system lock management and reduces resource overhead, thereby meeting the high availability and high concurrency access performance requirements of modern distributed systems.
