Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the TelecomTV breach identified under incident ID TELGOO1772110899.
The analysis begins with a detailed overview of TelecomTV's information like the linkedin page: https://www.linkedin.com/company/telecomtv, the number of followers: 18412, the industry type: Telecommunications and the number of employees: 23 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 751 and after the incident was 731 with a difference of -20 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 TelecomTV and their customers.
A newly reported cybersecurity incident, "Google Disrupts Major Chinese Cyber Espionage Campaign Targeting Global Telecom and Government Sectors", has drawn attention.
Google’s Threat Intelligence Group (GTIG), alongside Mandiant and other partners, recently dismantled a large-scale cyber espionage operation linked to the Chinese hacker group UNC2814.
The disruption is felt across the environment, and exposing Personally identifiable information (PII) such as names, phone numbers, and national ID numbers.
In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Terminated attacker-controlled Google Cloud Projects, disabled Google Sheets API infrastructure used for C2, blocked malicious traffic, and began remediation that includes Released Indicators of Compromise (IOCs) including malicious domains and IP addresses.
The case underscores how Disrupted, teams are taking away lessons such as The incident underscores the increasing complexity of defending against advanced persistent threats (APTs), particularly as attackers exploit legitimate cloud services to bypass traditional security measures.
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
