The content repeatedly describes threat actors and malware using PowerShell scripts/commands for execution, download, staging, reconnaissance, persistence, credential access, lateral movement, and defense evasion; e.g., "Sandworm Team used PowerShell scripts to run a credential harvesting tool in memory to evade defenses."

The content repeatedly describes victims being lured into opening malicious attachments, enabling macros, launching installers, clicking embedded files/links, or otherwise directly executing malicious content.

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.

"Anchor can create and execute services to load its payload"; "APT32's backdoor has used Windows services as a way to execute its malicious payload"; "Ragnar Locker has used sc.exe to execute a service that it creates"; "Shamoon creates a new service named 'ntssrv' to execute the payload"

Across the content, malware repeatedly 'adds Registry Run keys', 'creates Registry entries', 'modifies the Windows Registry', or 'overwrites registry keys' to maintain persistence.

During the 2016 Ukraine Electric Power Attack, Sandworm Team used an arbitrary system service to load at system boot for persistence for Industroyer. They also replaced the ImagePath registry value of a Windows service with a new backdoor binary.

Numerous malware families and threat groups are described as achieving persistence by adding values under Run/RunOnce/Policies\Explorer\Run Registry keys or by placing shortcuts/files in the Windows Startup folder.

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.

During the 2016 Ukraine Electric Power Attack, DLLs and EXEs with filenames associated with common electric power sector protocols were used to masquerade files.

Bad Rabbit has masqueraded as a Flash Player installer through the executable file install_flash_player.exe.

The content repeatedly describes adversaries and malware deleting files, directories, droppers, scripts, logs, archives, staged data, and other artifacts from compromised systems, e.g., 'APT29 has used SDelete to remove artifacts from victim networks' and 'Lazarus Group malware has deleted files in various ways, including "suicide scripts" to delete malware binaries from the victim.' | Several entries explicitly state files were deleted after exfiltration or upload, such as 'AppleSeed can delete files from a compromised host after they are exfiltrated,' 'Attor’s plugin deletes the collected files and log files after exfiltration,' and 'Ursnif has deleted data staged in tmp files after exfiltration.'

Agent Tesla has used ProcessWindowStyle.Hidden to hide windows. APT19 used -W Hidden to conceal PowerShell windows by setting the WindowStyle parameter to hidden. APT28 has used the WindowStyle parameter to conceal PowerShell windows.

Across the content, malware repeatedly 'adds Registry Run keys', 'creates Registry entries', 'modifies the Windows Registry', or 'overwrites registry keys' to maintain persistence.

The content repeatedly describes threat actors and malware using valid, stolen, forged, self-signed, or abused code-signing certificates to sign malware and appear legitimate, including examples such as AppleJeus using a valid digital signature from Sectigo, APT41 leveraging code-signing certificates, FIN7 signing Carbanak payloads, and SUNBURST being digitally signed by SolarWinds.

The content repeatedly describes malware and threat actors using commands and APIs such as ipconfig /all, ifconfig, arp -a, route print, nbtstat, netsh, GetAdaptersInfo, and GetIpNetTable to gather IP addresses, MAC addresses, DNS, DHCP, gateways, routing tables, ARP cache, proxy settings, domains, and network adapter/interface details.

The content repeatedly describes malware and threat actors obtaining lists of running processes, using utilities such as tasklist, ps, WMI, Get-Process, CreateToolhelp32Snapshot, EnumProcesses, and similar APIs/commands to enumerate active processes on victim systems.

The content is a long ATT&CK-style listing of malware and threat actors that collect host details such as OS version, hostname, architecture, CPU, memory, BIOS, language, and other basic system characteristics; examples include use of commands like systeminfo, ver, uname, sw_vers, and WMI queries.

The content repeatedly describes malware and threat actors listing files and directories, enumerating drives, searching for files by extension/name/path, retrieving file metadata, and browsing file systems (for example: "APT28 has used Forfiles to locate PDF, Excel, and Word documents during collection" and "cmd can be used to find files and directories with native functionality such as dir commands").

Adversaries may attempt to get a listing of security software, configurations, defensive tools, and sensors that are installed on a system or in a cloud environment.

Confucius has used a file stealer to steal documents and images... Patchwork developed a file stealer to search C:\ and collect files with certain extensions... Winter Vivern delivered a PowerShell script capable of recursively scanning victim machines looking for various file types before exfiltrating identified files via HTTP.

Agrius used a custom tool, sql.net4.exe, to query SQL databases and then identify and extract personally identifiable information... AppleSeed has automatically collected data from USB drives, keystrokes, and screen images before exfiltration... Ember Bear engages in mass collection from compromised systems during intrusions.

APT28 used a publicly available tool to gather and compress multiple documents... LoFiSe can collect all the files from the working directory every three hours and place them into a password-protected archive... NETWIRE can automatically archive collected data.

The content repeatedly describes threat actors and malware using HTTP and HTTPS for command and control, such as: "Sandworm Team used BlackEnergy to communicate between compromised hosts and their command-and-control servers via HTTP post requests."

During the 2025 Poland Wiper Attacks, the adversaries utilized Tor nodes for C2. APT28 has routed traffic over Tor and VPN servers to obfuscate their activities. A backdoor used by APT29 created a Tor hidden service to forward traffic from the Tor client to local ports 3389 (RDP), 139 (Netbios), and 445 (SMB) enabling full remote access from outside the network.

The content repeatedly describes malware and threat actors using SSL, TLS, HTTPS, RSA, AES, Blowfish, RC4, ECIES, Diffie-Hellman, OpenSSL, WolfSSL, and mutual TLS to protect command and control traffic.

ADVSTORESHELL exfiltrates data over the same channel used for C2... Agrius exfiltrated staged data using tools such as Putty and WinSCP, communicating with command and control servers... numerous malware and groups sent victim data, files, credentials, or host information over existing C2 channels.

During C0033, PROMETHIUM used StrongPity to exfiltrate to the C2 server using HTTPS.

BRATA has exfiltrated data to the C2 server using HTTP requests.

"Play has used Base64-encoded PowerShell scripts to disable Microsoft Defender," "StrongPity can use PowerShell to add files to the Windows Defender exclusions list," and "ZeroCleare can use a malicious PowerShell script to bypass Windows controls."

BlackByte Ransomware 'adds .JS and .EXE extensions to the Microsoft Defender exclusion list'; PureCrypter 'executed Set-MpPreference -ExclusionPath'; QakBot 'modify the Registry to add its binaries to the Windows Defender exclusion list'; Raspberry Robin 'add an exception to Microsoft Defender that excludes the entire main drive'; StrongPity 'add directories used by the malware to the Windows Defender exclusions list'; XLoader 'can add the path of its executable to the Microsoft Defender exclusion list'; ZIPLINE 'can add itself to the exclusion list for the Ivanti Connect Secure Integrity Checker Tool.'
