Joe Sandbox AI: Score: 7 Reasons: The brand 'Microsoft' is a well-known global technology company., The legitimate domain for Microsoft is 'microsoft.com'., The provided URL 'lotadmin.in' does not match the legitimate domain for Microsoft., The URL 'lotadmin.in' does not contain any recognizable association with Microsoft., The domain 'lotadmin.in' is not a known Microsoft domain or subdomain., The use of a completely different domain name is a common tactic in phishing attempts. DOM: 1.0.pages.csv

Source: PDF document	Joe Sandbox AI: PDF document contains QR code
Source: https://lotadmin.in/due/cigam/index#amxpdUBiaW9sZWdlbmQuY29t	Joe Sandbox AI: Page contains button: 'Slide to verify' Source: '1.0.pages.csv'

Source: 0.0.id.script.csv	Joe Sandbox AI: Detected suspicious JavaScript with source url: https://lotadmin.in/due/cigam/index#amxpdUBiaW9sZW... The script uses obfuscated code with base64 encoding and XOR decryption, which is a high-risk indicator (+3 points). It also performs aggressive DOM manipulation by writing directly to the document with `document.write`, which can be a vector for injecting malicious content (+2 points). The use of a hardcoded key for decryption suggests potential malicious intent, as it could be used to hide harmful payloads. No context is provided to suggest a legitimate use case, so no points are subtracted.
Source: 0.4.id.script.csv	Joe Sandbox AI: Detected suspicious JavaScript with source url: https://ust.tolegtynl.ru/Lhkb/#amxpdUBiaW9sZWdlbmQ... The script sends data to an obfuscated and suspicious domain (+3 points for obfuscated URL, +2 points for external data transmission). It also uses aggressive DOM manipulation by preventing form submission (+2 points). The domain 'ezmbsgzm.ru' appears suspicious, adding an additional point. The script redirects to 'azure.com', a trusted domain, but the overall behavior is inconsistent and potentially malicious.
Source: 1.1..script.csv	Joe Sandbox AI: Detected suspicious JavaScript with source url: https://www.larkus.ao/animal/script.js... The script contains obfuscated code, which is a high-risk indicator (+3 points). It also appears to be executing dynamic code, as suggested by the encoded script string, which is another high-risk indicator (+3 points). The lack of transparency and potential for data exfiltration or malicious redirection adds to the risk. Without further context or domain information, the script's behavior is suspicious, leading to a high-risk score.
Source: 0.2.id.script.csv	Joe Sandbox AI: Detected suspicious JavaScript with source url: https://ust.tolegtynl.ru/Lhkb/#amxpdUBiaW9sZWdlbmQ... The script contains obfuscated code using base64 encoding, which is a high-risk indicator (+3 points). It also includes aggressive DOM manipulation and event listeners, which are moderate-risk indicators (+2 points). The script attempts to redirect the user based on certain conditions, which can be suspicious (+3 points). The domain '0vX0.tolegtynl.ru' is not a well-known or trusted domain, adding to the suspicion (+1 point). Overall, the script demonstrates behaviors consistent with potentially malicious intent.

Description:	Adversaries may abuse Internet browser extensions to establish persistent access to victim systems. Browser extensions or plugins are small programs that can add functionality and customize aspects of Internet browsers. They can be installed directly or through a browser's app store and generally have access and permissions to everything that the browser can access.
Tactics:	Persistence
Data Sources:	Command: Command Execution, File: File Creation, Network Traffic: Network Connection Creation, Process: Process Creation, Windows Registry: Windows Registry Key Creation
Platforms:	Linux, macOS, 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

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:	File: File Metadata, File: File Modification, Module: Module Load, Process: OS API Execution, Process: Process Access, Process: Process Metadata, Process: Process Modification
Platforms:	Linux, macOS, Windows

Description:	Adversaries may inject malicious code into process via Extra Window Memory (EWM) in order to evade process-based defenses as well as possibly elevate privileges. EWM injection is a method of executing arbitrary code in the address space of a separate live process.
Tactics:	Defense Evasion, Privilege Escalation
Data Sources:	Process: OS API Execution
Platforms:	Windows

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:	Command: Command Execution, File: File Metadata, File: File Modification, Image: Image Metadata, Process: OS API Execution, Process: Process Creation, Process: Process Metadata, Scheduled Job: Scheduled Job Metadata, Scheduled Job: Scheduled Job Modification, Service: Service Creation, Service: Service Metadata

Description:	Adversaries may attempt to get information about running processes on a system. Information obtained could be used to gain an understanding of common software/applications running on systems within the network. Adversaries may use the information from Process 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, Process: OS API Execution, Process: Process Creation
Platforms:	Linux, macOS, Network, Windows

Description:	An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture. Adversaries may use the information from System Information 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, Process: OS API Execution, Process: Process Creation
Platforms:	IaaS, Linux, macOS, Network, Windows

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

Description:	Adversaries may use an OSI non-application layer protocol for communication between host and C2 server or among infected hosts within a network. The list of possible protocols is extensive.Specific examples include use of network layer protocols, such as the Internet Control Message Protocol (ICMP), transport layer protocols, such as the User Datagram Protocol (UDP), session layer protocols, such as Socket Secure (SOCKS), as well as redirected/tunneled protocols, such as Serial over LAN (SOL).
Tactics:	Command and Control
Data Sources:	Network Traffic: Network Traffic Content, Network Traffic: Network Traffic Flow
Platforms:	Linux, macOS, Network, Windows

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.
