The content repeatedly describes threat actors and malware using PowerShell to execute payloads, run commands, download additional malware, perform lateral movement, evade defenses, and execute scripts in memory. | Examples include: 'APT28 downloads and executes PowerShell scripts and performs PowerShell commands'; 'APT3 has used PowerShell on victim systems to download and run payloads after exploitation'; 'TA505 has used PowerShell to download and execute malware and reconnaissance scripts.'

The content repeatedly describes threat actors and malware using cmd.exe, the Windows command shell, to execute commands, launch payloads, run batch files, and automate actions on compromised hosts.

attempted to lure victims into enabling malicious macros within email attachments... prompted victims to accept macros... Word documents containing malicious macros.

The content repeatedly mentions malicious macros in Word/Excel documents, such as "enable macros," "embedded macros," and "macro-enabled documents."

has attempted to get victims to launch malicious Microsoft Word attachments delivered via spearphishing emails... has required user execution of a malicious MSI installer... has been executed through user installation of an executable disguised as a flash installer.

Sandworm Team leveraged Microsoft Office attachments which contained malicious macros that were automatically executed once the user permitted them... APT29 has used various forms of spearphishing attempting to get a user to open attachments... DarkGate is distributed through phishing links to VBS or MSI objects requiring user interaction for execution.

DarkTortilla can use cmd.exe to add registry keys for persistence. HeartCrypt can use the reg add command via cmd.exe for Registry modification. Ryuk has used cmd.exe to create a Registry entry to establish persistence.

The content repeatedly describes payloads, strings, configuration files, scripts, URLs, and binaries being obfuscated or encoded using Base64, XOR, RC4, AES, RSA, hex encoding, custom algorithms, and other methods across many malware families and threat actors.

actors used the following command to rename one of their tools to a benign file name: ren "%temp%\upload" audiodg.exe ... APT1 ... used ... AcroRD32.exe ... as a name for malware ... APT28 ... changed extensions on files containing exfiltrated data to make them appear benign ... APT32 has renamed a NetCat binary to kb-10233.exe to masquerade as a Windows update.

The content is a long ATT&CK-style listing of malware and threat groups that 'decrypt', 'decode', 'deobfuscate', 'unpack', or 'decompress' payloads, strings, configuration data, shellcode, and files prior to execution or use.

DarkTortilla can use cmd.exe to add registry keys for persistence. HeartCrypt can use the reg add command via cmd.exe for Registry modification. Ryuk has used cmd.exe to create a Registry entry to establish persistence.

Agent Tesla can gather credentials from a number of browsers... APT33 has used a variety of publicly available tools like LaZagne to gather credentials... TrickBot can obtain passwords stored in files from web browsers such as Chrome, Firefox, Internet Explorer, and Microsoft Edge... SELECT action_url, username_value, password_value FROM logins; CryptUnprotectData

Agent Tesla can gather credentials from a number of browsers... APT3 has used tools to dump passwords from browsers... APT41 used BrowserGhost, a tool designed to obtain credentials from browsers, to retrieve information from password stores... TrickBot can obtain passwords stored in files from web browsers such as Chrome, Firefox, Internet Explorer, and Microsoft Edge

The content repeatedly describes malware and threat actors collecting host details such as hostname, OS version, architecture, CPU, memory, BIOS, language, and other machine characteristics; e.g., "Action RAT has the ability to collect the hostname, OS version, and OS architecture of an infected host."

Examples include: "Babuk can enumerate disk volumes," "Confucius has used a file stealer that can examine system drives," and "XAgentOSX contains the getInstalledAPP function to run ls -la /Applications to gather what applications are installed."

Numerous entries mention enumerating drives, logical disks, disk type, free space, or volume information; examples include 'Babuk can enumerate disk volumes,' 'Cuba can enumerate local drives,' and 'TAINTEDSCRIBE can use DriveList to retrieve drive information.'

"Bazar can query the Registry for installed applications." / "BRONZE BUTLER has used tools to enumerate software installed on an infected host." / "LightSpy ... enumerate the Applications folder to collect the bundle name, bundle identifier, and version information..." / "Volt Typhoon has queried the Registry on compromised systems for information on installed software."

Andariel has collected large numbers of files from compromised network systems for later extraction... APT28 has retrieved internal documents from machines inside victim environments... BADNEWS crawls the victim's local drives and collects documents... many listed groups and malware collect files, documents, credentials, payment card data, or other information from compromised hosts.

The content repeatedly describes adversaries and malware storing collected data, command output, credentials, archives, or files in local temporary folders, working directories, hidden directories, registry locations, recycle bins, or specific files prior to exfiltration.

The content is a long ATT&CK-style listing showing numerous malware families and threat groups that 'use HTTP,' 'use HTTPS,' 'HTTP POST requests,' 'HTTP GET requests,' or 'HTTP/S' for command and control communications.

The content repeatedly describes malware and threat actors that can "download files from C2," "download additional payloads," "upload and download files," "retrieve payloads from the C2 server," and "copy files to remote machines."

ADVSTORESHELL exfiltrates data over the same channel used for C2.
