SOC Incident Response Playbook 9: MFA Fatigue Attack via Push Notification Bombing

Scenario
In 2025, attackers increasingly abuse Multi-Factor Authentication (MFA) push notifications
by triggering repeated sign-in attempts to overwhelm users into accepting an MFA prompt
(often called MFA fatigue). Once the victim unintentionally approves the prompt, attackers
gain access using stolen credentials, usually obtained from phishing or infostealers.

SaaS Environments

Scenario
In 2025 organisations increasingly integrate Large Language Models (LLMs) like ChatGPT or
proprietary agents with internal SaaS tools (e.g., Jira, Salesforce, Slack, GitHub) via plugins

In 2025 organisations increasingly rely on multi-cloud environments with automated
DevOps pipelines for deployment. Attackers exploit misconfigured Continuous
Integration/Continuous Deployment (CI/CD) tools—such as exposed GitHub Actions,
GitLab Runners, Jenkins or Bitbucket Pipelines—to compromise access tokens, inject
malicious code or pivot laterally across AWS, Azure and GCP accounts. This supply chain
compromise often goes undetected until code is deployed or secrets are leaked.

Using AI-Generated Personas

Scenario
By 2025, synthetic identity fraud has become one of the most difficult fraud types to
detect, particularly in fintech and digital banking platforms. Attackers use AI to generate
realistic customer profiles—complete with legitimate-looking documents, photos, voice
recordings and credit histories—to onboard fake users. These accounts pass KYC (Know
Your Customer) checks and are used to apply for loans, launder money or exploit referral
and cashback systems.

SOC Incident Response Playbook 47: Cross-Cloud SaaS Account Takeover via Identity
Federation Abuse

Scenario
In 2025, many enterprises rely on federated identity across multiple SaaS platforms using
SSO solutions like Azure AD, Okta or Google Workspace. Adversaries exploit
misconfigured trust relationships, OAuth abuse or stolen SAML assertions to pivot
between SaaS environments—taking over accounts across email, storage, project
management and DevOps platforms. This cross-cloud compromise bypasses MFA,
appears as a legitimate session and spreads laterally across the user ecosystem.

SOC Incident Response Playbook 48: AI Voice Phishing with Real-Time Translation in
Executive Impersonation Attacks

Scenario
In 2025, attackers leverage advanced voice synthesis tools with real-time language
translation to impersonate executives in voice calls, especially targeting multinational
teams. Using publicly available video/audio samples (e.g., from town halls, webinars or
social media), threat actors clone voices and initiate calls in the local language of the
victim—conducting high-pressure social engineering attacks. These calls bypass
traditional email filters and trick employees into performing urgent financial transfers,
changing credentials or sharing sensitive data.

SOC Incident Response Playbook 49: Firmware-Level Tampering in OT Supply Chains

Scenario
In 2025, adversaries target Operational Technology (OT) environments through
compromised firmware updates in the supply chain. Attackers insert malicious code into
legitimate firmware images before distribution. Once deployed on programmable logic
controllers (PLCs), industrial control systems (ICS) or smart sensors, the malware provides
persistent access, manipulates device behaviour or creates hidden backdoors. These
implants often bypass traditional AV, are difficult to detect and may lie dormant until
triggered.

SOC Incident Response Playbook 50: Rogue Browser Extension Compromise on
Enterprise Endpoints

Scenario
In 2025, threat actors increasingly use malicious or hijacked browser extensions to
compromise enterprise endpoints. These rogue extensions, often appearing as
productivity tools or AI assistants, are installed via browser app stores or silently pushed
via group policies. Once active, they exfiltrate credentials, session cookies, clipboard
contents and sensitive form inputs. Some extensions also hook into browser APIs for
lateral movement, phishing injection or downloading second-stage payloads.
