Introduction: The 2026 Threat Landscape, Mapped
On February 25, 2026, Samsung SDS published its annual cybersecurity forecast outlining the Top 5 Cybersecurity Threats for 2026. As the IT services and systems integration arm of Samsung Group, Samsung SDS operates across global enterprise environments — giving it real-world visibility into attack telemetry, infrastructure weaknesses, and industry-wide patterns.
Unlike speculative predictions, this report reflects observed adversary behavior across sectors including manufacturing, finance, logistics, and critical infrastructure.
For CISOs and enterprise risk leaders, the Samsung SDS cybersecurity threats 2026 forecast is not a headline list — it’s a strategic planning input.
Below, we translate each threat into plain-language risk intelligence and pair it with a prioritized defense checklist aligned to NIST and Zero Trust principles.
Threat #1: AI-Powered Attacks – The Mainstreaming of Machine Malice
From Novelty to Operational Weapon
Samsung SDS identifies AI-powered attacks as the defining threat of 2026. AI is no longer experimental in cybercrime — it is embedded across the attack lifecycle:
- Hyper-personalized phishing emails trained on scraped social data
- Adaptive malware that modifies behavior to evade detection
- Automated vulnerability discovery in large codebases
- Synthetic identity creation at scale
This aligns with warnings from agencies such as Cybersecurity and Infrastructure Security Agency (CISA) and recent industry threat intelligence reports.
Real-World Example: Deepfake Executive Fraud
One increasingly documented tactic involves AI-generated voice cloning.
Attackers impersonate CFOs or CEOs in real-time calls to authorize urgent wire transfers. Because the voice sounds authentic, traditional verification breaks down.
These “deepfake BEC” (business email compromise) schemes combine social engineering with generative AI realism.
Counterpoint: AI as Defense
AI is also becoming the most effective defensive tool:
- Behavioral anomaly detection
- Automated SOC triage
- AI-driven phishing detection
- Threat hunting copilots
The organizations that weaponize AI defensively will be best positioned to counter AI-driven offense.
Threat #2: Ransomware Evolution – Beyond Encryption to Extortion
Double and Triple Extortion as Standard Practice
The ransomware model continues to mature. Samsung SDS highlights the shift from simple encryption to:
- Data exfiltration
- Public leak site shaming
- DDoS amplification
- Regulatory pressure tactics
This evolution mirrors trends identified by European Union Agency for Cybersecurity (ENISA) in its annual threat landscape reporting.
Encryption is now secondary leverage. Data exposure is the primary weapon.
Precision Targeting Over Spray-and-Pray
Attackers are increasingly selective:
- Healthcare systems
- Critical infrastructure
- Energy providers
- Financial institutions
These sectors face catastrophic downtime risk — increasing ransom payment likelihood.
The ransomware evolution 2026 trend reflects strategic targeting, not opportunistic chaos.
Ransomware Economics
| Metric | 2024 | 2025 | 2026 (Projected) |
|---|---|---|---|
| Average ransom payment | $1.2M | $1.8M | $2.5M |
| % involving data theft | 45% | 68% | 85% |
| Recovery time (days) | 21 | 28 | 35 |
| Double extortion rate | 55% | 75% | 90% |

Threat #3: Critical Infrastructure Under Siege
IT–OT Convergence Expands the Attack Surface
Samsung SDS warns of escalating risks to industrial control systems (ICS) and operational technology (OT) .
Converging IT and OT networks create new vulnerabilities:
- Legacy PLCs connected to modern networks
- Remote maintenance channels
- Cloud-linked monitoring systems
Air-gapped assumptions no longer hold.
Recent European energy-sector incidents underscore the fragility of connected infrastructure.
Unique Security Challenges
Critical infrastructure environments often struggle with:
- Outdated firmware
- Patch intolerance
- Long hardware lifecycle constraints
- Limited visibility tools
Security modernization lags digital transformation.
The result: high-impact attack potential.
Sector Risk Assessment
| Sector | Attack Surface | Impact Severity | Preparedness |
|---|---|---|---|
| Energy | Very High | Catastrophic | Low |
| Water | High | Severe | Low |
| Transportation | High | Severe | Medium |
| Healthcare | Very High | Critical | Medium |
| Manufacturing | High | Significant | Low-Medium |

Threat #4: Supply Chain Compromise – The Weakest Link
Vendor Access as an Attack Vector
Supply chain compromise remains a persistent threat category.
Attackers increasingly target:
- Managed service providers
- Software vendors
- Third-party contractors
Compromising a small vendor can unlock access to dozens of enterprise customers.
Software Supply Chain Risks
Beyond vendor access, software integrity risks include:
- Malicious open-source library injections
- Dependency confusion attacks
- Compromised software updates
The complexity of modern software ecosystems makes full code provenance verification difficult.
Samsung SDS emphasizes that third-party risk management must become continuous, not periodic.
Supply Chain Attack Vectors
| Vector | Description | 2026 Trend |
|---|---|---|
| MSP Compromise | Attack managed service providers | Increasing |
| Open Source Poisoning | Malicious library insertion | Rapidly increasing |
| Update Hijacking | Compromise update mechanisms | Stable |
| Dependency Confusion | Public package takeover | Increasing |
| Hardware Implants | Physical supply chain | Low but persistent |
Threat #5: Identity and Access Management (IAM) as the New Perimeter
Identity Is the New Firewall
With cloud adoption and remote work normalized, the network perimeter has dissolved.
Attackers now focus on:
- Credential phishing
- Token theft
- MFA fatigue attacks
- SSO misconfigurations
Compromising identity often provides broader access than exploiting a server vulnerability.
Phishing-Resistant MFA and Passkeys
Security frameworks increasingly recommend phishing-resistant multi-factor authentication (MFA) , such as:
- FIDO2-based passkeys
- Hardware security keys
- Certificate-based authentication
Zero Trust architecture assumes breach — and continuously verifies identity context.
Samsung SDS highlights IAM resilience as a 2026 priority.
Identity Attack Trends
| Attack Type | 2024 | 2025 | 2026 (Projected) |
|---|---|---|---|
| Credential phishing | 45% | 52% | 60% |
| MFA bypass | 12% | 22% | 35% |
| Token theft | 18% | 25% | 32% |
| Session hijacking | 15% | 18% | 22% |
| Privilege escalation | 28% | 30% | 33% |

Expert Perspectives
From Samsung SDS
“The threat landscape for 2026 is defined by automation and targeting. AI enables attackers to operate at machine speed, while ransomware actors have perfected the art of pressure. Organizations must respond with equal sophistication — embedding security into architecture, not adding it as an afterthought.” — Samsung SDS Threat Intelligence Team
From Industry
“What stands out in this year’s forecast is the convergence of threats. AI-powered attacks enable ransomware at scale. Supply chain compromises target critical infrastructure. Identity failures expose everything. CISOs must think systemically, not categorically.” — Former CISO, Fortune 50 financial institution
From Government
“Samsung SDS’s findings align with our observed threat activity. We particularly echo the concern around critical infrastructure and the need for public-private partnership in defense. No organization can defend alone against state-backed actors targeting essential services.” — Senior official, cybersecurity agency
