In today’s rapidly evolving threat landscape, organizations must maintain continuous visibility, strong detection mechanisms, and rapid response capabilities to defend against increasingly sophisticated cyber adversaries. Our Security Operations framework demonstrates proven effectiveness in identifying, analyzing, and mitigating high-risk network threats in real time.
Below are two recent case studies that highlight our proactive detection, investigative rigor, and containment strategies.
Incident Overview Our monitoring systems detected a network connection attempt over SSH (port 22) originating from a public source and targeting a destination geolocated to China. The destination address was flagged as blacklisted by community threat intelligence feeds.
The alert was triggered under a Prohibited Country Access Policy Violation, as connections to restricted geographies are tightly controlled due to their frequent association with malicious campaigns and command-and-control (C2) infrastructure.
Although the observed session was short-lived with no confirmed successful authentication, such attempts are widely recognized as reconnaissance or initial access techniques commonly leveraged in remote exploitation campaigns.
Threat Intelligence Mapping The activity aligns with the following MITRE ATT&CK techniques:
Risk Assessment While no confirmed compromise was observed, the attempt reflects a high-risk pattern commonly associated with:
Response & Preventive Controls Our recommended mitigation strategy included immediate blocking of the destination via firewall geo-restriction, a thorough review of source host activity, and the enforcement of MFA and key-based authentication for all SSH gateways.
Incident Overview A high-severity alert identified suspicious outbound traffic from a host within the internal Jobsites network. The host established 11 TCP connections to a service provider in Canada over port 9999 a non-standard port often utilized for backdoor communications.
Traffic analysis revealed sustained packet exchange patterns consistent with command-and-control (C2) activity rather than legitimate application behavior. Additionally, the same host accessed a known blacklisted domain via HTTPS (port 443), which carried confirmed malicious confidence indicators.
The alert was categorized as:
Risk Assessment Multiple indicators strongly suggested compromise:
Unlike the previous case, this activity demonstrated characteristics of an active infection rather than a mere access attempt.
Immediate Containment & Remediation Strategy Our response protocol included the immediate isolation of the affected host from the network followed by full forensic investigation and memory analysis. We conducted comprehensive malware scanning with an emphasis on persistence mechanisms, scheduled tasks, and startup entries to prevent further propagation or data exfiltration.
These incidents demonstrate our organization’s core cybersecurity strengths:
Modern cyber threats range from opportunistic reconnaissance to advanced command-and-control driven malware campaigns. Through layered monitoring, strict access governance, and rapid response execution, our security operations ensure resilience against both emerging and established threats.
