Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the NortonLifeLock breach identified under incident ID AVGGENNORAVA1788452879.
The analysis begins with a detailed overview of NortonLifeLock's information like the linkedin page: https://www.linkedin.com/company/nortonlifelock, the number of followers: 34743, the industry type: Computer and Network Security and the number of employees: 688 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 693 and after the incident was 688 with a difference of -5 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 NortonLifeLock and their customers.
On 30 August 2026, GenDigital (Avast) disclosed Privilege Escalation issues under the banner "Zero-Day Privilege-Escalation Flaw in Avast Antivirus Exposed via Public PoC".
Security researcher Chaotic Eclipse (GitHub handle: MSNightmare) has released a public proof-of-concept (PoC) exploit, dubbed *PrettyPrague*, for a zero-day privilege-escalation vulnerability in Avast Antivirus.
The disruption is felt across the environment, affecting Windows 11 25H2 systems with Avast Antivirus, and exposing Protected credentials (SAM database).
Formal response steps have not been shared publicly yet.
The case underscores how Unverified (no CVE or vendor confirmation), and recommending next steps like Monitor GenDigital advisories, review endpoint telemetry for unusual activity, implement detection rules for suspicious execution chains involving antivirus sandbox components.
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%), with evidence including zero-Day Privilege-Escalation Flaw in Avast Antivirus, and exploit targets the Windows Security Account Manager (SAM) database and Abuse Elevation Control Mechanism: Bypass User Account Control (T1548.002) with moderate to high confidence (80%), with evidence including bypass security controls via the Avast Sandbox, and escalate privileges to NT AUTHORITY\SYSTEM. Under the Credential Access tactic, the analysis identified OS Credential Dumping: Security Account Manager (T1003.002) with high confidence (90%), with evidence including exploit targets the Windows Security Account Manager (SAM) database, and access protected credentials. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (80%), with evidence including disable security tools, and avast Sandbox designed to isolate suspicious files. Under the Persistence tactic, the analysis identified Create or Modify System Process: Windows Service (T1543.003) with moderate to high confidence (70%), with evidence including install persistent malware, and spawn a SYSTEM-level command shell. Under the Execution tactic, the analysis identified Native API (T1106) with moderate to high confidence (70%), with evidence including poC includes C/C++ source files, compiled x64 binaries, and spawn a SYSTEM-level command shell. Under the Initial Access tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate confidence (60%), with evidence including attackers with existing code execution on a system, and local Exploitation attack vector. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
