Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Verizon breach identified under incident ID VER1778085829.
The analysis begins with a detailed overview of Verizon's information like the linkedin page: https://www.linkedin.com/company/verizon, the number of followers: 1455266, the industry type: IT Services and IT Consulting and the number of employees: 101542 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 538 and after the incident was 423 with a difference of -115 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 Verizon and their customers.
A newly reported cybersecurity incident, "Rise in Third-Party Breaches as a Primary Cybersecurity Threat in 2025", has drawn attention.
The 2025 Verizon Data Breach Investigations Report highlights a sharp increase in third-party breaches, now accounting for nearly 30% of all incidents.
Impact assessments are still underway, so the full scope is not yet clear.
Formal response steps have not been shared publicly yet.
The case underscores how teams are taking away lessons such as Traditional third-party risk programs (point-in-time assessments, questionnaires, external scoring) are ineffective against modern attacks. Organizations must adopt intelligence-led, continuous monitoring to detect active compromises in real time, and recommending next steps like Map digital and third-party exposure to understand risk, Detect reconnaissance and targeting activity at the earliest stages and Harden AI systems against manipulation and abuse.
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 Initial Access tactic, the analysis identified Supply Chain Compromise (T1195) with high confidence (90%), with evidence including third-party breaches account for nearly 30% of all incidents, and attackers exploit trusted third-party connections and Compromise Software Supply Chain (T1195.002) with moderate to high confidence (80%), supported by evidence indicating 97% of major financial firms impacted through fourth parties (vendors of vendors). Under the Lateral Movement tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate to high confidence (80%), supported by evidence indicating attackers move laterally through trusted pathways. Under the Credential Access tactic, the analysis identified Adversary-in-the-Middle (T1557) with moderate to high confidence (70%), supported by evidence indicating exploiting trusted connections to infiltrate secure networks. Under the Defense Evasion tactic, the analysis identified Subvert Trust Controls (T1553) with high confidence (90%), with evidence including attackers systematically exploiting trusted connections, and security teams blind to real-time threats and Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating trusted third-party connections used as primary attack vector. Under the Reconnaissance tactic, the analysis identified Active Scanning (T1595) with moderate to high confidence (80%), supported by evidence indicating aI-powered adversaries map trust relationships, identify vulnerabilities and Gather Victim Org Information (T1591) with moderate to high confidence (70%), supported by evidence indicating recommendation to detect reconnaissance and targeting activity. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating attackers move laterally through trusted pathways (implies data exfiltration). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
