Multi AV Scanner detection for submitted file

Yara detected Mirai

Sample deletes itself

Sample is packed with UPX

Detected TCP or UDP traffic on non-standard ports

ELF contains segments with high entropy indicating compressed/encrypted content

Sample contains only a LOAD segment without any section mappings

Sample listens on a socket

Sample tries to kill a process (SIGKILL)

Tries to connect to HTTP servers, but all servers are down (expired dropper behavior)

Uses the "uname" system call to query kernel version information (possible evasion)

Mirai	Mirai is one of the first significant botnets targeting exposed networking devices running Linux. Found in August 2016 by MalwareMustDie, its name means "future" in Japanese. Nowadays it targets a wide range of networked embedded devices such as IP cameras, home routers (many vendors involved), and other IoT devices. Since the source code was published on "Hack Forums" many variants of the Mirai family appeared, infecting mostly home networks all around the world.

Description:	Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit. This is common behavior that can be used across different platforms and the network to evade defenses.
Tactics:	Defense Evasion
Data Sources:	Command: Command Execution, File: File Creation, File: File Metadata, Module: Module Load, Process: OS API Execution, Process: Process Creation, Script: Script Execution, WMI: WMI Creation, Windows Registry: Windows Registry Key Creation
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may delete files left behind by the actions of their intrusion activity. Malware, tools, or other non-native files dropped or created on a system by an adversary (ex: Ingress Tool Transfer ) may leave traces to indicate to what was done within a network and how. Removal of these files can occur during an intrusion, or as part of a post-intrusion process to minimize the adversary's footprint.
Tactics:	Defense Evasion
Data Sources:	Command: Command Execution, File: File Deletion
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	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. This may include things such as firewall rules and anti-virus. Adversaries may use the information from Security Software Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
Tactics:	Discovery
Data Sources:	Command: Command Execution, Firewall: Firewall Enumeration, Firewall: Firewall Metadata, Process: OS API Execution, Process: Process Creation
Platforms:	Azure AD, Google Workspace, IaaS, Linux, macOS, Office 365, SaaS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may employ a known encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Despite the use of a secure algorithm, these implementations may be vulnerable to reverse engineering if secret keys are encoded and/or generated within malware samples/configuration files.
Tactics:	Command and Control
Data Sources:	Network Traffic: Network Traffic Content
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may communicate using a protocol and port pairing that are typically not associated. For example, HTTPS over port 8088or port 587as opposed to the traditional port 443. Adversaries may make changes to the standard port used by a protocol to bypass filtering or muddle analysis/parsing of network data.
Tactics:	Command and Control
Data Sources:	Network Traffic: Network Traffic Content, Network Traffic: Network Traffic Flow
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may communicate using OSI application layer protocols to avoid detection/network filtering by blending in with existing traffic. Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.
Tactics:	Command and Control
Data Sources:	Network Traffic: Network Traffic Content, Network Traffic: Network Traffic Flow
Platforms:	Linux, macOS, Windows
