Multi AV Scanner detection for dropped file

Multi AV Scanner detection for submitted file

Sigma detected: NanoCore

Yara detected Nanocore RAT

.NET source code contains very large array initializations

Allocates memory in foreign processes

C2 URLs / IPs found in malware configuration

Hides that the sample has been downloaded from the Internet (zone.identifier)

Initial sample is a PE file and has a suspicious name

Injects a PE file into a foreign processes

Uses an obfuscated file name to hide its real file extension (double extension)

Uses dynamic DNS services

Writes to foreign memory regions

Antivirus or Machine Learning detection for unpacked file

Contains capabilities to detect virtual machines

Contains functionality to launch a process as a different user

Contains long sleeps (>= 3 min)

Creates a process in suspended mode (likely to inject code)

Detected TCP or UDP traffic on non-standard ports

Detected potential crypto function

Dropped file seen in connection with other malware

Drops PE files

Enables debug privileges

Found a high number of Window / User specific system calls (may be a loop to detect user behavior)

Found inlined nop instructions (likely shell or obfuscated code)

Installs a raw input device (often for capturing keystrokes)

Internet Provider seen in connection with other malware

May sleep (evasive loops) to hinder dynamic analysis

Monitors certain registry keys / values for changes (often done to protect autostart functionality)

PE file contains strange resources

Queries the volume information (name, serial number etc) of a device

Sample execution stops while process was sleeping (likely an evasion)

Sample file is different than original file name gathered from version info

Uses 32bit PE files

Uses code obfuscation techniques (call, push, ret)

Uses reg.exe to modify the Windows registry

Yara signature match

Description:	Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Compromised credentials may be used to bypass access controls placed on various resources on systems within the network and may even be used for persistent access to remote systems and externally available services, such as VPNs, Outlook Web Access and remote desktop. Compromised credentials may also grant an adversary increased privilege to specific systems or access to restricted areas of the network. Adversaries may choose not to use malware or tools in conjunction with the legitimate access those credentials provide to make it harder to detect their presence.
Tactics:	Defense Evasion, Initial Access, Persistence, Privilege Escalation
Data Sources:	AWS CloudTrail logs, Authentication logs, Process monitoring, Stackdriver logs
Platforms:	AWS, Azure, Azure AD, GCP, Linux, macOS, Office 365, SaaS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key. Adding an entry to the "run keys" in the Registry or startup folder will cause the program referenced to be executed when a user logs in. These programs will be executed under the context of the user and will have the account's associated permissions level.
Tactics:	Persistence, Privilege Escalation
Data Sources:	File monitoring, Windows Registry
Platforms:	Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls. Windows uses access tokens to determine the ownership of a running process. A user can manipulate access tokens to make a running process appear as though it is the child of a different process or belongs to someone other than the user that started the process. When this occurs, the process also takes on the security context associated with the new token.
Tactics:	Defense Evasion, Privilege Escalation
Data Sources:	API monitoring, Access tokens, Authentication logs, Process command-line parameters, Process monitoring, Windows event logs
Platforms:	Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges. Process injection is a method of executing arbitrary code in the address space of a separate live process. Running code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via process injection may also evade detection from security products since the execution is masked under a legitimate process.
Tactics:	Defense Evasion, Privilege Escalation
Data Sources:	API monitoring, DLL monitoring, File monitoring, Named Pipes, Process monitoring
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation. This may include manipulating file metadata, tricking users into misidentifying the file type, and giving legitimate task or service names.
Tactics:	Defense Evasion
Data Sources:	Binary file metadata, File monitoring, Process command-line parameters, Process monitoring
Platforms:	Linux, macOS, Windows

Description:	Adversaries may employ various means to detect and avoid virtualization and analysis environments. This may include changing behaviors based on the results of checks for the presence of artifacts indicative of a virtual machine environment (VME) or sandbox. If the adversary detects a VME, they may alter their malware to disengage from the victim or conceal the core functions of the implant. They may also search for VME artifacts before dropping secondary or additional payloads. Adversaries may use the information learned from [Virtualization/Sandbox Evasion](https://attack.mitre.org/techniques/T1497) during automated discovery to shape follow-on behaviors.

Description:	Adversaries may set files and directories to be hidden to evade detection mechanisms. To prevent normal users from accidentally changing special files on a system, most operating systems have the concept of a ‘hidden’ file. These files don’t show up when a user browses the file system with a GUI or when using normal commands on the command line. Users must explicitly ask to show the hidden files either via a series of Graphical User Interface (GUI) prompts or with command line switches ( `dir /a` for Windows and `ls –a` for Linux and macOS).

Description:	Adversaries may perform software packing or virtual machine software protection to conceal their code. Software packing is a method of compressing or encrypting an executable. Packing an executable changes the file signature in an attempt to avoid signature-based detection. Most decompression techniques decompress the executable code in memory. Virtual machine software protection translates an executable's original code into a special format that only a special virtual machine can run. A virtual machine is then called to run this code.

Description:	Adversaries may use methods of capturing user input to obtain credentials or collect information. During normal system usage, users often provide credentials to various different locations, such as login pages/portals or system dialog boxes. Input capture mechanisms may be transparent to the user (e.g. Credential API Hooking ) or rely on deceiving the user into providing input into what they believe to be a genuine service (e.g. Web Portal Capture ).

Description:	An adversary may compress and/or encrypt data that is collected prior to exfiltration. Compressing the data can help to obfuscate the collected data and minimize the amount of data sent over the network. Encryption can be used to hide information that is being exfiltrated from detection or make exfiltration less conspicuous upon inspection by a defender.
