Detects the abuse of the Windows Background Intelligent Transfer Service (BITS) via the bitsadmin command-line tool or PowerShell's Start-BitsTransfer to download files (such as .exe, .dll, or .ps1) or facilitate potential persistence. Adversaries use these methods to transfer malicious payloads stealthily in the background or to maintain persistence on a compromised host.
Detects the use of BITSAdmin or PowerShell 'Start-BitsTransfer' to download files from non-reputable/non-Microsoft sources to suspicious directories such as Temp, AppData, or ProgramData, which is a common technique for ingress tool transfer during malware delivery.
Detects the use of BITSAdmin or PowerShell 'Start-BitsTransfer' to download files from non-reputable/non-Microsoft sources to suspicious directories such as Temp, AppData, or ProgramData, which is a common technique for ingress tool transfer during malware delivery.
Detects the use of BITSAdmin to download files to suspicious directories (Temp, AppData, ProgramData) or to register persistent command execution via the /SetNotifyCmdLine parameter. This detection correlates process execution events with BITS Client operational log events to confirm the completion or status of the BITS job.
This rule detects the use of native Windows utilities certutil.exe and bitsadmin.exe for potentially malicious purposes. Specifically, it flags certutil.exe being used for decoding or cached URL operations, and bitsadmin.exe being used to initiate file transfers from remote URLs or network paths. These tools are commonly abused by attackers for file staging, ingress tool transfer, and deobfuscation of malicious payloads.
Detects the use of bitsadmin.exe to create or modify Background Intelligent Transfer Service (BITS) jobs, specifically when combined with the /setnotifycmdline flag. This technique is used by adversaries to download malicious payloads and trigger their execution upon job completion, often bypassing network security controls that might otherwise flag traditional download-and-execute activity.
Detects the use of bitsadmin.exe to initiate file transfers from remote URLs to sensitive or writable system directories, or the use of /SetNotifyCmdLine to define a command to execute upon job completion. These techniques are often used by adversaries to download payloads or establish persistence via BITS jobs.
Detects the use of the BITSAdmin utility to create, add, resume, or complete download jobs, which may indicate an adversary attempting to download malicious files or tools onto a system.
Detects the use of BITSAdmin or the PowerShell Start-BitsTransfer cmdlet for downloading files from the internet or local network, often used by attackers to perform ingress tool transfer or to maintain persistence via BITS jobs.
Detects the use of the BITSAdmin utility to transfer files or set notification command lines. BITSAdmin is a legitimate Windows utility often abused by adversaries to download malicious files or achieve persistence/execution via BITS jobs.
Detects the use of bitsadmin.exe to initiate file transfers from remote HTTP/HTTPS locations. This behavior is frequently used by adversaries to download malicious payloads onto a host using legitimate system utilities.
This rule detects the use of BITSAdmin or PowerShell 'Start-BitsTransfer' to initiate file transfer jobs. These tools can be abused by adversaries to download malicious payloads or exfiltrate data, often bypassing standard firewall restrictions. The rule specifically filters out legitimate Microsoft-signed processes to reduce noise.
Detects the use of BITSAdmin or PowerShell 'Start-BitsTransfer' to download files from common public file sharing and code repository sites, which is a known technique for adversaries to stage or download malicious payloads.
Detects the use of BITSAdmin or PowerShell 'Start-BitsTransfer' to initiate background data transfer jobs pointing to non-Microsoft or non-Windows Update domains. This technique is commonly used by adversaries for C2 communication or to download malicious payloads.
Detects the use of BITSAdmin or the PowerShell Start-BitsTransfer cmdlet for downloading files from the internet or local network, often used by attackers to perform ingress tool transfer or to maintain persistence via BITS jobs.
Detects the use of BITSAdmin to download files from remote URLs. Attackers frequently abuse BITSAdmin, a legitimate Windows administrative tool, to download malicious payloads or secondary tools from external servers.
Detects the use of the BITSAdmin command-line utility to initiate file transfers from external sources to user-writable directories or temporary folders. This behavior is indicative of living-off-the-land (LotL) techniques where adversaries use legitimate system binaries to download and potentially execute malicious files.
Detects the use of BITSAdmin or PowerShell 'Start-BitsTransfer' to download files from common public file sharing and code repository sites, which is a known technique for adversaries to stage or download malicious payloads.
Detects the use of BITSAdmin to create or modify background intelligent transfer jobs. Attackers often abuse BITSAdmin to download malicious payloads (ingress tool transfer) or to execute commands when a transfer job completes or errors, which can be leveraged for persistence or arbitrary code execution.
