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 646 and after the incident was 583 with a difference of -63 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 Instagram and their customers.

On 09 January 2026, Instagram disclosed Data Breach issues under the banner "Instagram’s Hidden Vulnerabilities: The Breach That Shook 17.5 Million Accounts".

Personal information belonging to approximately 17.5 million Instagram users was exposed in a significant data leak, involving sensitive data such as emails, phone numbers, and usernames.

The disruption is felt across the environment, affecting Instagram API, User Accounts, and exposing Emails, phone numbers, usernames, biographical details, with nearly 17.5 million records at risk.

In response, moved swiftly to contain the threat with measures like Encouraged users to report suspicious activity, rolled out security best practice reminders, and began remediation that includes Recommended password changes, enabling two-factor authentication (2FA), and stakeholders are being briefed through Public statements downplaying the breach, assurances that internal systems were not compromised.

The case underscores how Ongoing, teams are taking away lessons such as Recurring challenges in maintaining robust security for API interfaces, need for stronger encryption and regular audits, importance of transparent reporting mechanisms, and user-centric data protection policies, and recommending next steps like Use password managers to generate unique credentials, Avoid reusing passwords across sites and Enable app-based two-factor authentication (2FA) over SMS, with advisories going out to stakeholders covering Businesses and influencers advised to monitor for unauthorized access and diversify their online presence to mitigate risks.

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.

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 Exploit Public-Facing Application (T1190) with moderate to high confidence (80%), with evidence including outdated or poorly secured API interfaces, and aPI Vulnerability Exploitation and Acquire Infrastructure: Domains (T1583.001) with moderate confidence (60%), supported by evidence indicating third-party scraping or historical vulnerabilities. Under the Credential Access tactic, the analysis identified Steal Application Access Token (T1528) with moderate to high confidence (70%), supported by evidence indicating instagram API exploited via automated scripts. Under the Collection tactic, the analysis identified Data from Cloud Storage (T1530) with high confidence (90%), supported by evidence indicating emails, phone numbers, usernames, biographical details compromised and Automated Collection (T1119) with moderate to high confidence (80%), supported by evidence indicating automated scripts used to harvest user details. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating data allegedly sold on dark web forums and Exfiltration Over Web Service (T1567) with moderate to high confidence (70%), supported by evidence indicating data circulating on dark web markets. Under the Impact tactic, the analysis identified Data Destruction (T1485) with lower confidence (30%), supported by evidence indicating no direct evidence, but implied by data exposure risks and Disk Wipe: Disk Structure Wipe (T1561.002) with lower confidence (20%), supported by evidence indicating no evidence of disk wiping, but included due to breach impact. Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating third-party scraping activities leveraging legitimate access and Hide Artifacts: Hidden Files and Directories (T1564.001) with moderate confidence (50%), supported by evidence indicating historical vulnerabilities in data handling. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
