Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Cisco breach identified under incident ID VEESONCIS1775140482.
The analysis begins with a detailed overview of Cisco's information like the linkedin page: https://www.linkedin.com/company/cisco, the number of followers: 7281720, the industry type: Software Development and the number of employees: 95370 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 631 and after the incident was 523 with a difference of -108 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 Cisco and their customers.
A newly reported cybersecurity incident, "Akira Ransomware Group Accelerates Attacks, Completing Full Compromise in Under an Hour", has drawn attention.
Security researchers at Halcyon have identified a significant escalation in ransomware attack speed, with the Akira group now executing full attack lifecycles from initial access to data encryption in as little as one hour.
The disruption is felt across the environment, and exposing True, plus an estimated financial loss of $244 million in ransom payments (estimated).
Formal response steps have not been shared publicly yet.
Overall, the incident is a reminder of why proactive monitoring and strong governance matter.
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 Exploit Public-Facing Application (T1190) with high confidence (90%), supported by evidence indicating exploiting vulnerabilities in internet-facing VPN appliances and backup solutions, Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating credential theft, password spraying, and lack of MFA exploited, Spearphishing Attachment (T1566.001) with moderate to high confidence (70%), supported by evidence indicating spearphishing listed as an attack vector, and Spearphishing Link (T1566.002) with moderate to high confidence (70%), supported by evidence indicating spearphishing listed as an attack vector. Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate confidence (60%), supported by evidence indicating living-off-the-land tools like WinRAR, WinSCP used for data staging. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating compromised credentials used to maintain access. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with moderate to high confidence (70%), supported by evidence indicating exploiting vulnerabilities in VPN appliances and backup solutions. Under the Defense Evasion tactic, the analysis identified Disable or Modify Tools (T1562.001) with high confidence (90%), supported by evidence indicating disables security software to evade detection, Masquerading (T1036) with moderate to high confidence (80%), supported by evidence indicating uses living-off-the-land tools like FileZilla, WinRAR, WinSCP, and Data Encrypted for Impact (T1486) with moderate to high confidence (70%), supported by evidence indicating intermittent encryption scrambling as little as 1% of a file. Under the Credential Access tactic, the analysis identified Password Spraying (T1110.003) with moderate to high confidence (80%), supported by evidence indicating password spraying listed as an attack vector and Credentials from Password Stores (T1555) with moderate to high confidence (70%), supported by evidence indicating credential theft listed as an attack vector. Under the Discovery tactic, the analysis identified File and Directory Discovery (T1083) with moderate to high confidence (70%), supported by evidence indicating data staging and encryption imply file discovery. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating data exfiltration as part of double-extortion model. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating data exfiltration before encryption in double-extortion model and Exfiltration Over Web Service (T1567) with moderate to high confidence (70%), supported by evidence indicating tools like FileZilla, WinSCP, RClone used for data staging. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating files encrypted as part of ransomware attack and Data Destruction (T1485) with moderate confidence (60%), supported by evidence indicating intermittent encryption may corrupt files. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
