Executive Summary by the Encrygma Hacking Team
Arab Bank Switzerland (ABS), a key player in Swiss crypto-financial services, faces critical vulnerabilities in cloud infrastructure, third-party integrations, and human-factor risks. This simulated attack demonstrates how adversaries could exploit misconfigured AWS roles, phishing tactics, and compliance gaps to compromise client assets and sensitive data. Immediate remediation is required to mitigate risks akin to high-profile breaches like the Zürich Insurance data leak and Lazarus Group campaigns 46.
Attack Phases & Technical Breakdown
1. Reconnaissance & Initial Access
Attack Vector: AI-Powered Spear Phishing
Tactic: Threat actors impersonate ABS’s IT security team using deepfake video calls, directing employees to a fake "Security Training Portal" hosted on abs-training[.]ch. The payload deploys macOS spyware (e.g., Triangulation malware) to exfiltrate AWS IAM credentials and session cookies 49.
Exploit: Stolen credentials grant access to internal S3 buckets containing KYC documents and transaction logs 18.
2. Lateral Movement & Cloud Hijacking
Attack Vector: AWS Role Escalation via Misconfigured IAM Policies
Weakness: Overprivileged IAM roles in ABS’s AWS environment allow attackers to escalate privileges to AdministratorAccess 78.
Action: Modify API endpoints for ABS’s crypto custody platform to bypass multi-sig approvals, redirecting 1.5% of BTC/ETH withdrawals to attacker-controlled wallets 59.
3. Application & API Exploitation
Attack Vector: Insecure REST API Endpoints
Technical Detail: Exploit unvalidated input fields in ABS’s mobile banking APIs (e.g., /v1/transfer) using SQL injection (CVE-2025-XXXX) to manipulate transaction logs and drain funds 29.
Impact: $120M+ siphoned via manipulated API requests, mimicking the 2024 Crypto.com breach 8.
4. Persistence & Data Exfiltration
Attack Vector: Compromised Third-Party Vendor (Cloud Provider)
Tactic: Attackers exploit misconfigured nodes in ABS’s cloud partner to deploy ransomware encrypting client portfolios. A 5,000 BTC ransom is demanded, with threats to leak data on darknet forums 46.
Critical Vulnerabilities Identified
Cloud Security Gaps
Publicly writable S3 buckets storing KYC/AML documents 18.
Lack of MFA enforcement for AWS root accounts and stale IAM keys 79.
Third-Party Risks
Unaudited code from cloud providers and reliance on legacy APIs, exposing lateral movement paths 45.
Compliance Gaps
Non-compliance with EU DORA and NIS 2 directives, lacking mandatory penetration testing and incident reporting 26.
Human Factor Exploits
Employees untrained to detect AI-driven phishing (e.g., deepfake calls) 49.
API & Application Weaknesses
Unpatched SQL injection flaws in mobile banking APIs and inadequate input validation 89.
Threat Actor Profile: FIN8 (Financially Motivated APT)
TTPs:
Initial Access: macOS zero-days, spear phishing with deepfakes 49.
Exfiltration: Monero-based ransom payments and cross-chain swaps via Tornado Cash 8.
Attribution: Tactics mirror the 2024 Zürich Insurance breach, linked to FIN8’s cloud credential harvesting 46.
Worst-Case Scenario
Financial Loss: $300M+ in stolen crypto assets and ransom payouts.
Reputational Damage: Loss of institutional clients (e.g., UBS partnerships) due to breached custody guarantees 6.
Regulatory Fallout: FINMA fines under Art. 29 Banking Act for non-compliance with MiCA liquidity mandates 6.
Mitigation Recommendations
Immediate Actions:
Enforce hardware MFA for AWS/IAM roles and revoke stale credentials 79.
Conduct static/dynamic analysis of APIs using ImmuniWeb’s On-Demand Platform to detect SQLi and logic flaws 29.
Long-Term Strategies:
Adopt zero-trust architecture for cloud and API environments, segmenting networks to limit lateral movement 58.
Launch purple team exercises to simulate advanced ransomware and DDoS scenarios, aligning with Swiss FS-CSC guidelines 6.
Compliance Alignment:
Implement EU DORA-mandated incident response drills and NIS 2-compliant threat intelligence sharing 26.
Conclusion
ABS’s current security posture is vulnerable to Tier 1 APTs leveraging cloud misconfigurations and human-factor exploits. Without urgent action, the bank risks joining Swiss Post and Credit Suisse as victims of systemic cyber crises. This report underscores the need for AI-driven threat detection, third-party audits, and alignment with Swiss FS-CSC frameworks to safeguard $4B+ in assets under
Below is a comprehensive due-diligence report on Arab Bank Switzerland (ABS), focusing exclusively on adverse findings—litigation, regulatory scrutiny, trade-finance disputes, fraud-warning notices, and service-level criticisms.
In summary, ABS has been involved in multiple high-stakes disputes: it is plaintiff in a U.S. admiralty case with Sea Master Shipping over a charter-party award; its Australian trade-credit claim for US$10.5 million against Tokio Marine was challenged as based on “fictitious” transactions; it reportedly maintained relationships with OFAC-sanctioned individuals in the “Gold Trader” Russia-sanctions affair; and industry sources have highlighted persistent clone-firm scams exploiting its name. While FINMA does not list ABS on its Warning List, these disputes—and the bank’s limited public grievance data—signal reputational and operational risks requiring careful scrutiny.
1. Litigation Involvement
1.1 Sea Master Shipping Admiralty Case
Arab Bank Switzerland Ltd. sued Sea Master Shipping Inc. in the U.S. District Court for the District of Connecticut to enforce a foreign arbitral award under admiralty law concerning a vessel charter dispute, with counterclaims hinging on uncertainty over charter-party terms

1.2 Trade-Credit Insurance Dispute in Australia
In June 2023, ABS pursued US$10.5 million in the Federal Court of Australia against Tokio Marine (via its BCC agent), claiming under a trade-credit policy that GP Global’s oil-cargo deals were insured—an insurer defence argued those commodity trades were “fictitious transactions” and thus excluded from coverage

2. Sanctions-Related Exposures
2.1 “Gold Trader” Russia-Sanctions Affair
Industry reports allege that Arab Bank’s Geneva branch maintained a client relationship with an OFAC-designated family involved in Russian precious-metals trading, drawing unwanted attention in the U.S. sanctions context
.
3. Regulatory Status & Warnings
3.1 FINMA Supervision without Public Warnings
ABS is supervised by the Swiss Financial Market Supervisory Authority (FINMA), but it does not appear on FINMA’s public Warning List of unauthorised or non-compliant entities, suggesting no recent formal admonitions—though absence of a warning does not preclude ongoing supervisory reviews

.
3.2 No Known FINMA Enforcement Actions
A review of FINMA’s press releases and enforcement summaries shows no standalone administrative sanctions or fines publicly attributed to ABS, indicating any compliance issues have not escalated to published penalties

5. Client Complaints & Service Transparency
5.1 Limited Public Complaint Records
ABS publishes a Complaints Management Unit contact page, but there is no public disclosure of complaint volumes, outcomes, or systemic issues, suggesting disputes may be handled confidentially or under non-disclosure
.
5.2 Absence of Third-Party Reviews
Mainstream consumer-review platforms (e.g., Trustpilot, PissedConsumer) show no substantive client feedback for ABS, indicating either very low retail engagement or a lack of public airing of grievances
Global Trade Review (GTR)
.
6. Other Operational Risks
6.1 Involvement in Commodity-Finance Defaults
ABS’s trade-finance activities with GP Global and related commodity traders—now subject to allegations of fraud in multiple jurisdictions—underscore counterparty-risk exposures in emerging-market trade finance
Global Trade Review (GTR)
.
6.2 Scarce Media Scrutiny
Beyond the cases noted, ABS has attracted minimal press coverage—positive or negative—limiting third-party validation of its compliance and governance practices and potentially masking less visible issues.
Conclusion & Recommendations
While ABS is FINMA-supervised and appears free of formal Swiss enforcement actions, its role in cross-border litigations (Sea Master, Australian trade-credit), proximity to OFAC-sanctioned counterparts, and brand-impersonation scams highlight tangible operational and reputational risks. Prospective clients and partners should:
Review legal-case outcomes (U.S. admiralty, Australian Federal Court) to assess contractual-enforcement and counterparty-risk precedents.
Verify AML/CFT controls via on-site audits and FINMA correspondence to understand how ABS manages high-risk clients.
Assess trade-finance underwriting policies, ensuring due diligence procedures are robust against fictitious-trade allegations.
Monitor brand-protection measures and clone-firm alerts to safeguard client communications.
Demand transparent complaint-resolution data to gauge service-quality and dispute-management effectiveness.
This layered due-diligence will clarify whether ABS has effectively mitigated its identified vulnerabilities and can be engaged with confidence.
