Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Broadcom breach identified under incident ID BRO1775111316.
The analysis begins with a detailed overview of Broadcom's information like the linkedin page: https://www.linkedin.com/company/broadcom, the number of followers: 616560, the industry type: Semiconductor Manufacturing and the number of employees: 55707 employees
After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 755 and after the incident was 753 with a difference of -2 which is could be a good indicator of the severity and impact of the incident.
In the next step of the video, we will analyze in more details the incident and the impact it had on Broadcom and their customers.
On 30 March 2026, Broadcom (Symantec) disclosed Local Privilege Escalation (LPE) issues under the banner "High-Severity Symantec DLP Agent Flaw Grants SYSTEM Privileges to Attackers".
A critical local privilege escalation (LPE) vulnerability in the Symantec Data Loss Prevention (DLP) Agent for Windows (CVE-2026-3991, CVSS 7.8) allows low-privileged attackers to gain full SYSTEM-level control of affected machines.
The disruption is felt across the environment, affecting Windows machines running vulnerable Symantec DLP Agent versions.
In response, moved swiftly to contain the threat with measures like Patch deployment (DLP 25.1 MP1, 16.1 MP2, 16.0 RU2 HF9, 16.0 RU1 MP1 HF12, 16.0 MP2 HF15), and began remediation that includes Apply security patches to vulnerable DLP Agent versions.
The case underscores how Resolved, teams are taking away lessons such as Hardcoded file paths in privileged processes pose significant security risks. Regular security audits and testing for such vulnerabilities are critical, and recommending next steps like 1. Apply the latest security patches for Symantec DLP Agent immediately. 2. Monitor for unusual activity in DLP agent processes. 3. Restrict write permissions to critical system directories, with advisories going out to stakeholders covering Broadcom released patches and advised customers to update to fixed versions.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
MITRE ATT&CK® Correlation Analysis
Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with high confidence (90%), supported by evidence indicating critical local privilege escalation (LPE) vulnerability...allows low-privileged attackers to gain full SYSTEM-level control and Hijack Execution Flow: DLL Side-Loading (T1574.002) with high confidence (90%), supported by evidence indicating attackers can create...and place a malicious OpenSSL configuration file and DLL in the path...executing the attacker’s code with SYSTEM rights. Under the Defense Evasion tactic, the analysis identified Masquerading: Match Legitimate Name or Location (T1036.005) with moderate to high confidence (80%), supported by evidence indicating malicious payload runs within the trusted DLP agent process, evading endpoint security and monitoring tools and Hijack Execution Flow: DLL Side-Loading (T1574.002) with moderate to high confidence (80%), supported by evidence indicating edpa.exe...loads...malicious OpenSSL configuration file and DLL...executing the attacker’s code with SYSTEM rights. Under the Initial Access tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating exploitation requires an attacker to already have basic access to a target system. Under the Persistence tactic, the analysis identified Create or Modify System Process: Windows Service (T1543.003) with moderate to high confidence (70%), supported by evidence indicating dLP Agent restarts...loads malicious files...executing the attacker’s code with SYSTEM rights. Under the Impact tactic, the analysis identified Resource Hijacking (T1496) with moderate confidence (60%), supported by evidence indicating privilege escalation is a key tactic in ransomware and cyber espionage campaigns. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
