Common Ingress Points: How Malware Sneaks into Corporate Networks

Malware, a relentless threat in the digital world, employs diverse, often clever methods to breach companies, leveraging technological flaws and human error alike. Phishing attacks deceive employees into clicking harmful links or downloading tainted attachments, representing a primary entry point. Attackers also exploit unpatched or outdated software to introduce malware. Drive-by downloads present another risk, with compromised websites silently installing malware without user interaction. Furthermore, malware disguises itself in legitimate-looking software or spreads via removable media like USB drives, exploiting users’ trust. Social engineering tactics further trick users into sidestepping security measures, leading to unintentional malware installation. Recognizing and understanding these common entryways are vital for companies to devise robust defense strategies and reduce malware infection risks effectively.

This proactive tool scans your digital infrastructure for known vulnerabilities that could be exploited by malware, offering an added layer of preemptive defense by identifying and addressing weak spots before they can be leveraged in an attack. Coupled with the Logstail Cyber Threat Intelligence Platform, which leverages cutting-edge global threat intelligence to foresee and forestall potential malware attacks, Logstail not only confronts existing threats but also fortifies defenses against the malware of tomorrow. Together, these features encapsulate a comprehensive defense strategy, propelling the Logstail Platform to the forefront of cybersecurity innovation.

POC Scenario: Detecting a Malware Infiltration

Step 1: Logstail Agent Installation

The scenario begins with the Logstail Agent already installed on an endpoint within the company’s network. This endpoint could be a workstation, server, or any device susceptible to malware attacks. The Logstail Agent is configured to monitor activities and changes in common directories known to be targets for malware delivery, such as the Downloads folder.

Step 2: Monitoring for Integrity

The Logstail Agent actively monitors the integrity of files within these watched directories. This includes tracking the creation, modification, and deletion of files, essentially keeping a vigilant eye on any unusual or unauthorized changes, which could be indicative of a security breach.

Step 3: Phishing Email Received and Malicious File Downloaded

In this scenario, a phishing email cleverly bypasses the email security filter and lands in the inbox of an unsuspecting user. The email contains a link or an attachment, which the user is tricked into downloading. This action results in a malicious file being saved to the Downloads folder, a common repository for new files on any device.

Step 4: Malicious File Detection

Upon the malicious file’s arrival in the monitored directory, the Logstail Agent detects the new file’s presence almost immediately. It then proceeds to calculate the file’s SHA256 hash—a unique identifier for the file, which is used to check the file’s integrity and identity.

Step 5: Verification Against LogstailCTI

The SHA256 hash of the suspicious file is swiftly cross-referenced with the Logstail Cyber Threat Intelligence (LogstailCTI) database. This database contains information about known malware signatures, including hashes of malicious files. The comparison reveals a match, confirming the file’s malicious nature.

Step 6: Alerting Mechanism Triggered

Upon confirmation that the file is indeed malicious, the Logstail Security Information and Event Management (SIEM) system springs into action. It generates an alert regarding the detected threat and automatically sends an email notification to the designated security personnel. This alert includes details about the malicious file, such as its location, name, and hash value, enabling a swift and informed response to mitigate the threat.

Further Investigation

• Using Logstail CTI

Utilizing the URL to Logstail Cyber Threat Intelligence (CTI) provided in the alert email, you gain access to a wealth of detailed information regarding the identified malicious file. Logstail CTI platform not only allows you to delve deeper into the specifics of the threat but also enables you to disseminate this critical data as an Indicator of Compromise (IOC) across your organization. The dissemination of such intelligence is pivotal; it cultivates a shared awareness of the threat landscape, bolstering your organization’s collective defense mechanisms. By sharing insights into the nature, tactics, and signatures of attacks, you empower your network’s stakeholders to recognize and respond to similar threats more efficiently. This communal knowledge serves as a cornerstone of a robust cybersecurity framework, enhancing the ability to preemptively address potential vulnerabilities and fortify defenses against future incursions.

• Using Logstail SIEM Integrity Monitor Dashboard

Leveraging the Logstail SIEM Integrity Monitor Dashboard, investigators and IT security teams can conduct a thorough examination of file modifications, pinpointing the origins and pathways of the malware-infected file within the network. This dashboard serves as a critical tool, offering a comprehensive view of the file system’s integrity across monitored endpoints. By utilizing this, you can trace the chronological sequence of events leading to the malicious file’s download, including unauthorized changes, file creation, or alterations within sensitive directories.

• Using Logstail Reports Feature

Logstail Report Plugin plays a pivotal role in the efficient dissemination of information regarding the malware incident. This feature enables the swift creation and distribution of comprehensive reports detailing the incident’s specifics, including the nature of the malicious file, its entry point, affected systems, and the timeline of events. By leveraging the plugin, your security team can generate clear, actionable reports that not only facilitate a deeper understanding of the incident among your company’s stakeholders but also promote a coordinated response effort. The reports, enriched with insights and analytics, can be shared across company’s departments and with senior management, ensuring that everyone is informed and aligned on the incident and on mitigation strategies.
