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 666 with a difference of -85 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 INSS Israel and their customers.
Israel’s National Security Institute recently reported "Iran-Linked Hacking Group 'Handala' Claims Breach of Israeli National Security Official’s Email", a noteworthy cybersecurity incident.
An Iran-affiliated hacking group, Handala, announced that it compromised the email account of Ilan Steiner, Chief Financial Officer at Israel’s National Security Institute, extracting over 50,000 documents.
The disruption is felt across the environment, affecting Email account, and exposing 50,000 documents, with nearly 50,000 records at risk.
Formal response steps have not been shared publicly yet.
The case underscores how Unverified.
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 Phishing: Spearphishing Link (T1566.002) with moderate to high confidence (80%), supported by evidence indicating compromised the email account of Ilan Steiner, Chief Financial Officer and Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating compromised the email account of Ilan Steiner. Under the Credential Access tactic, the analysis identified Brute Force: Password Cracking (T1110.002) with moderate confidence (60%), supported by evidence indicating email account compromise suggests possible credential access and Credentials from Password Stores (T1555) with moderate confidence (50%), supported by evidence indicating email account compromise may involve stored credentials. Under the Collection tactic, the analysis identified Email Collection: Remote Email Collection (T1114.002) with high confidence (90%), supported by evidence indicating extracting over 50,000 documents from email account and Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating intelligence-related research, Mossad-linked files compromised. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating 50,000 documents extracted, data exfiltration confirmed and Exfiltration Over Web Service (T1567) with moderate to high confidence (70%), supported by evidence indicating hack-and-leak operations suggest web-based exfiltration. Under the Impact tactic, the analysis identified Data Destruction (T1485) with lower confidence (40%), supported by evidence indicating hack-and-leak operations may involve data destruction and Data Encrypted for Impact (T1486) with lower confidence (30%), supported by evidence indicating no evidence of encryption, but possible in hack-and-leak. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with moderate to high confidence (70%), supported by evidence indicating email compromise suggests C2 via web protocols. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
