Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Cyber Threat Intelligence ® breach identified under incident ID CYBMIC1772619962.
The analysis begins with a detailed overview of Cyber Threat Intelligence ®'s information like the linkedin page: https://www.linkedin.com/company/cyber-threat-intel, the number of followers: 213326, the industry type: Security and Investigations and the number of employees: 13 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 757 and after the incident was 733 with a difference of -24 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 Cyber Threat Intelligence ® and their customers.
A newly reported cybersecurity incident, "Ransomware Groups Abuse Microsoft’s AzCopy for Stealthy Data Exfiltration", has drawn attention.
Ransomware operators are exploiting Microsoft’s trusted Azure data transfer tool, AzCopy, to covertly exfiltrate sensitive data before encryption.
The disruption is felt across the environment, affecting Azure Blob storage, corporate IT infrastructure, and exposing Sensitive data.
In response, moved swiftly to contain the threat with measures like Revoke SAS tokens, Rotate Azure storage keys and Coordinate with cloud providers, and began remediation that includes Monitor anomalous AzCopy activity, Restrict direct internet access from servers and Limit AzCopy execution to approved hosts and accounts.
The case underscores how teams are taking away lessons such as Ransomware groups are increasingly weaponizing trusted cloud tools like AzCopy, requiring organizations to adapt detection strategies to account for legitimate utilities being turned against them, and recommending next steps like Monitor for anomalous AzCopy activity (e.g., off-hours transfers, unusual data volumes), Use User and Entity Behavior Analytics (UEBA) to flag abnormal file access and Restrict direct internet access from servers to known endpoints.
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 Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating attackers gain access through compromised Azure credentials or storage keys. Under the Credential Access tactic, the analysis identified Cloud Instance Metadata API (T1552.005) with moderate to high confidence (70%), supported by evidence indicating compromised Azure credentials or storage keys used for access and Unsecured Credentials (T1552) with moderate to high confidence (80%), supported by evidence indicating shared Access Signature (SAS) tokens embedded with permissions. Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with high confidence (90%), supported by evidence indicating leveraging legitimate AzCopy utility to evade detection, Masquerading (T1036) with moderate to high confidence (80%), supported by evidence indicating azCopy, a trusted utility, used to blend malicious activity into routine IT ops, Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (80%), supported by evidence indicating attackers deleting local log files (%USERPROFILE%\.azcopy) to erase evidence, and Hide Artifacts: Hidden Files and Directories (T1564.001) with moderate to high confidence (70%), supported by evidence indicating use of legitimate cloud infrastructure and standard HTTPS traffic. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating target recent, high-value data using --include-after flag. Under the Exfiltration tactic, the analysis identified Transfer Data to Cloud Account (T1537) with high confidence (90%), supported by evidence indicating azCopy used to bulk-upload stolen files to attacker-controlled Azure Blob storage, Exfiltration Over Alternative Protocol (T1048) with moderate to high confidence (80%), supported by evidence indicating exfiltration via HTTPS connections to *.blob.core.windows.net, and Automated Exfiltration (T1020) with moderate to high confidence (70%), supported by evidence indicating use of --cap-mbps flag to throttle transfer speeds. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (90%), supported by evidence indicating ransomware groups BianLian and Rhysida encrypt data post-exfiltration. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
