Primary Threats: Detailed Discovery and Analysis
The following three threats were identified as the most critical for Tigress Airlines based on the incident details and sector-wide trends.
1. Ransomware Targeting Core IT & Booking Systems
- Discovery Process: Research into the 2024 Japan Airlines (JAL) incident revealed that operational disruptions can be the result of sophisticated ransomware. By correlating this with general aviation trends, I discovered that ransomware is a top-tier threat for airlines. Specific intelligence indicates that groups like Akira use compromised credentials to access external systems like VPNs, which aligns perfectly with Tigress's discovery of "unexpected access attempts from an external location".
- STRIDE Category & Mechanism: This is primarily a Denial of Service and Information Disclosure threat. Adversaries first gain access, exfiltrate sensitive customer and operational data, and then encrypt critical systems, rendering them unusable. The "elevated privileges" noted in Tigress's logs suggest the attacker may have moved laterally to compromise the central booking database.
- Trust Boundary Breach: The attack breaches the Staff/System Admin to Core Database trust boundary. Attackers exploit stolen credentials or vulnerabilities in staff access points to reach the sensitive data repository, as seen in incidents targeting companies like Collins Aerospace that provided software to multiple airlines.
2. Supply Chain & Third-Party Service Provider Attacks
- Discovery Process: Analysis of the JAL attack and other recent breaches (e.g., Air France/KLM, Qantas) consistently points to initial compromise through third-party vendors. For JAL, reports suggest the breach may have originated via a compromised service platform. Research confirms that the aviation ecosystem's heavy reliance on partners like cloud providers and payment processors creates a broad, hard-to-secure attack surface.
- STRIDE Category & Mechanism: This represents a Tampering and Elevation of Privilege threat. By compromising a trusted third-party's systems (e.g., a cloud management portal or API gateway), attackers can inject malicious code, manipulate data flows, or steal credentials to gain a foothold in Tigress's network. This bypasses direct perimeter defenses.
- Trust Boundary Breach: This directly violates the Third-Party Provider to Tigress Cloud Network trust boundary. A breach at a technology partner (like a global cloud provider) can serve as a trusted conduit into Tigress's core environment, undermining the security of integrated systems.
3. Credential Theft and Insider Threats
- Discovery Process: The FBI warning about groups like "Scattered Spider" specifically targeting airlines through social engineering to steal IT administrator credentials was a key finding. This technique matches the "elevated privileges" and external access in the Tigress logs. Further research into incidents like the Qantas Frequent Flyer theft showed that compromised credentials from third-party contractors can lead to significant fraud and data loss.
- STRIDE Category & Mechanism: This is an Elevation of Privilege and Spoofing threat. Attackers use vishing (voice phishing) or sophisticated phishing to trick employees or IT support into revealing passwords or resetting Multi-Factor Authentication (MFA). Once inside, they masquerade as legitimate users, potentially leading to data exfiltration or preparing systems for a ransomware attack.
- Trust Boundary Breach: This exploits the Human Factor within all trust boundaries. Whether it's a staff member, a third-party contractor, or an IT administrator, human vulnerability can be leveraged to gain unauthorized access to sensitive zones, including the customer database and internal operational systems.

To transition this threat analysis into a formal risk mitigation plan for Assessment 3, you would need to establish clear risk criteria (e.g., based on likelihood and impact) to score each threat. From there, you can develop a mitigation table with specific actions, responsible parties, timelines, and costs.
I hope this structured assessment provides a solid foundation for your report. If you would like to explore the risk criteria or initial steps for one of these mitigation strategies, feel free to ask.
