In this Rankiteo incident briefing, we review the TOPPAN Next Tech breach identified under incident ID TOP1502015111625.

The analysis begins with a detailed overview of TOPPAN Next Tech's information like the linkedin page: https://www.linkedin.com/company/toppannexttech, the number of followers: 601, the industry type: Printing Services and the number of employees: 70 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 624 with a difference of -131 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 TOPPAN Next Tech and their customers.

The case underscores how Ongoing (CSA assisting TNT with investigations), with advisories going out to stakeholders covering ELD monitoring situation; CSA advising TNT on containment.

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 confidence (60%), supported by evidence indicating ransomware attack with no specified vector; printing vendor with public-facing systems and Valid Accounts (T1078) with moderate confidence (50%), supported by evidence indicating no explicit evidence, but common ransomware entry via compromised credentials. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (95%), with evidence including ransomware attack with data encryption likely, and standard ransomware operation. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (70%), with evidence including customer data of 11,000+ individuals compromised, and identity theft risk such as possible implies data likely exfiltrated. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (85%), supported by evidence indicating customer data of 11,000+ individuals (DBS Bank and Bank of China) accessed. Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate confidence (60%), supported by evidence indicating standard ransomware TTP; no explicit logs mentioned, but likely cleanup post-encryption and Impair Defenses: Disable/Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating ransomware typically disables security tools; no explicit evidence but implied by attack success. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with moderate confidence (50%), supported by evidence indicating no direct evidence, but common for ransomware to move laterally via RDP. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate to high confidence (70%), supported by evidence indicating ransomware often dumps credentials for lateral movement; implied by data access across systems. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
