The Geopolitics of Cybersecurity (2025): How Nations Hack, Signal, and Escalate By CyberDudeBivash • Date: September 21, 2025 (IST)

-

 


Executive summary

Cyber is the preferred zone for gray-zone competition in 2025. Russia leans on destructive OT-adjacent ops and high-end espionage; China pre-positions quietly inside Western critical infrastructure using “living off the land” (LOTL) tradecraft; Iran mixes state units with hacktivists to coerce & retaliate; North Korea funds its weapons programs via record-breaking crypto heists. Law-enforcement disruption ops, sanctions, and joint advisories are now routine instruments of statecraft and deterrence.

Load-bearing facts (2024–2025)

  • PRC’s Volt/Salt Typhoon: multi-year, stealthy pre-positioning across U.S. critical sectors; Five-Eyes+ partners keep issuing joint guidance (and naming Chinese contractors) while DOJ runs botnet clean-ups. CISA+2National Security Agency+2

  • Russia (Sandworm/APT29): destructive wipers against Ukraine’s energy sector; simultaneous strategic espionage (e.g., Midnight Blizzard) against Western targets. We Live Security+1

  • Iran & proxies: U.S. government warned in June 2025 of likely IR-linked activity against U.S. firms & critical infra; pro-Israel “Predatory Sparrow” hit Iran’s banking/crypto ecosystem—illustrating cyber coercion during kinetic flashpoints. Reuters+2CISA+2

  • North Korea: FBI attributes the $1.5B Bybit theft (Feb 2025) to DPRK’s TraderTraitor/Lazarus—state revenue via cybercrime at geopolitical scale. Internet Crime Complaint Center+1

TL;DR — What’s new in 2025

  • Pre-positioning over smash-and-grab. PRC activity emphasizes long-term access in comms, energy, transport, and water—explicitly for disruption in crisis. CISA

  • OT pressure and wipers. Russia’s Sandworm continues destructive campaigns (e.g., ZEROLOT), keeping energy operators on wartime footing. We Live Security+1

  • Cross-domain signaling. Cyber strikes pair with kinetic events (e.g., Iran/Israel crisis), while governments publish joint advisories in near-real time. National Security Agency+1

  • Disruption as strategy. DOJ-style botnet deletions (e.g., PlugX) and takedowns are now standard deterrence levers. Department of Justice

Why states hack (and how they signal)

  1. Espionage: strategic/political intel; cloud identity abuse; supply-chain access.

  2. Coercion & sabotage: OT-adjacent pressure on energy, water, transport; wipers to raise costs. We Live Security

  3. Influence & lawfare: information ops timed to elections or crises; sanctions/indictments as counter-signals.

  4. Revenue (DPRK): industrial-scale crypto theft as state financing. Internet Crime Complaint Center

Signaling mechanics: Attributions and joint advisories (NSA/CISA/FBI + allies), sanctions lists, public technical detail (TTPs/IOCs), and court-authorized botnet removals now serve as deterrence messaging as much as defense. National Security Agency+1

Campaign archetypes to watch

1) PRC: Pre-positioning for crisis effects

  • TTPs: LOTL, valid accounts, edge-device exploitation, long dwell time.

  • Targets: comms, energy, transport, water/wastewater; activity stretching years. CISA

  • Policy response: joint NSA/CISA global guidance (Aug 2025) naming PRC-linked firms; hunt guidance and mitigations published. National Security Agency

2) Russia: Wipers + strategic espionage

  • Sandworm destructive tooling (e.g., ZEROLOT) against Ukrainian energy and European targets. We Live Security

  • SVR/APT29 (Midnight Blizzard) uses identity attacks and token abuse to siphon high-value data. (See Microsoft’s guidance for responders.) Microsoft

3) Iran: Retaliatory blends of state + hacktivists

  • U.S. advisory June 2025: heightened risk to U.S. firms/critical infra amid regional conflict; emphasis on edge-device exploitation. Reuters

  • Predatory Sparrow operations on Iran’s Bank Sepah and crypto exchange Nobitex show cyber as strategic coercion. WIRED

4) North Korea: Financially motivated statecraft

5) Spillover & neighbors

  • Russian-linked activity against European critical services (e.g., Poland’s hospitals/water sector) underscores region-wide gray-zone pressure. Financial Times

Escalation & deterrence: the 2025 playbook

  • Defend-forward operations: DOJ/Allies dismantle state-run botnets; publicize affidavits to shape norms. Department of Justice

  • Sanctions & lawfare: target state organs, cut-outs, and contractors; some governments float ransom payment limits to starve ecosystems. Reuters+1

  • Collective attributions: multination coalitions issue timely, technical alerts—useful for both hunting and geopolitics. National Security Agency

Reality check: Despite escalatory rhetoric, most campaigns stay below kinetic thresholds, avoiding mass-casualty effects while building leverage.

Defender’s field guide (enterprise & government)

Hunt what they actually do

  • LOTL & valid-account abuse: prioritize identity protection, centralized logging, and anomaly hunting tuned for admin utilities & native binaries. CISA+1

  • Edge devices: patch and replace EoL SOHO gear; enforce MFA and config baselines on routers/VPNs. CISA

  • OT boundary: strict segmentation, unidirectional gateways where feasible; rehearse manual ops for critical processes. (See annual OT threat reviews.) Dragos Cyber Security+1

Minimum viable hardening 

  • Identity: phishing-resistant MFA; conditional access; admin isolation forests; monitored break-glass.

  • Exposure: inventory & close inbound from internet; broker devices via mTLS; short-lived tokens.

  • Data: label & zone; encrypt in transit; block exfil to unknown SaaS; DLP on crown-jewel repos.

  • Detection: hunt for PowerShell/WMI/PSExec, abnormal RDP, and cloud token reuse; alert on newly created admins out of hours.

  • Response: pre-built takedown playbooks (rotate cloud secrets, invalidate tokens, disable service principals).

  • Third parties: score suppliers on identity, logging, and patch SLOs; require attestation during incidents.

Case snapshots (2024–2025)

  • Volt/Salt Typhoon: U.S. and allies warn of persistent access in critical infrastructure, with assessed goal to disrupt OT during crises—advice includes LOTL hunting and edge-device patching. CISA

  • Joint NSA/CISA global advisory (Aug 2025): details TTPs, IOCs, and names PRC contractors supporting operations. National Security Agency

  • Sandworm “ZEROLOT”: destructive wiper campaigns underscore the need for IT/OT segmentation and rehearsed failovers. We Live Security+1

  • Bybit heist (DPRK): FBI pins $1.5B theft on TraderTraitor/Lazarus—a reminder that financial crime is a state lever. Internet Crime Complaint Center

  • Poland CI pressure: recent reporting of Russian-linked ops on hospitals and city water infrastructures shows regional spillover risk. Financial Times

30-day hardening plan (use now)

Week 1 — Visibility: turn on cloud & identity logs; forward to SIEM; baseline admin & service principal behavior.
Week 2 — Identity: enforce phishing-resistant MFA; rotate long-lived tokens; restrict legacy protocols; per-tenant admin workstations.
Week 3 — Exposure: patch/replace edge devices; purge unused external access; enforce mTLS and client certs for device brokers.
Week 4 — Drill: run a Volt-style LOTL hunt and a Sandworm-style wiper tabletop; measure time-to-contain & token/key rotation speed.
(Use CISA’s LOTL guidance to seed detections.) CISA

FAQs

Is “cyber war” real war?
Most activity stays below armed conflict thresholds—but it shapes battlespace, intelligence, and domestic resilience.

Are attacks escalating?
Yes in persistence and breadth, not always in visible impact; pre-positioning is the trend to worry about. CISA

What about OT?
OT disruption risk is highest where IT/OT boundaries blur and incident response isn’t practiced regularly. Dragos Cyber Security

CyberDudeBivash Rapid Advisory — WordPress Plugin: Social-Login Authentication Bypass (Threat Summary & Emergency Playbook)

-
Image
  TL;DR: A class of vulnerabilities in WordPress social-login / OAuth plugins can let attackers bypass normal authentication flows and obtain an administrative session (or create admin users) by manipulating OAuth callback parameters, reusing stale tokens, or exploiting improper validation of the identity assertions returned by providers. If you run a site that accepts social logins (Google, Facebook, Apple, GitHub, etc.), treat this as high priority : audit, patch, or temporarily disable social login until you confirm your plugin is safe. This advisory gives you immediate actions, detection steps, mitigation, and recovery guidance. Why this matters (short) Social-login plugins often accept externally-issued assertions (OAuth ID tokens, authorization codes, user info). If the plugin fails to validate provider signatures, nonce/state values, redirect URIs, or maps identities to local accounts incorrectly , attackers can craft requests that the site accepts as authenticated. ...

Hackers Injecting Malicious Code into GitHub Actions to Steal PyPI Tokens CyberDudeBivash — Threat Brief & Defensive Playbook

-
Image
  SUMMARY  Attackers are modifying GitHub Actions workflows (via compromised accounts, malicious PRs, or forged commits) to add steps that exfiltrate PyPI (or other package registry) publishing tokens. With those tokens they publish backdoored packages or download private packages — a supply-chain multiplier. Defend by eliminating long-lived secrets, switching to OIDC/ephemeral credentials, hardening workflow controls, monitoring workflow changes and secret usage, and rotating tokens immediately if you suspect compromise. How attackers typically operate  Gain write access to repo or CI/CD config (via compromised developer account, stolen token, privilege abuse, or merge of malicious PR). Modify or add a workflow file that runs in the repo’s runner context (self-hosted or GitHub-hosted). Add steps that read repository secrets (e.g., PYPI_TOKEN ) or create credentials files ( ~/.pypirc ), then send the token to attacker-controlled endpoints or push a malicious p...

Exchange Hybrid Warning: CVE-2025-53786 can cascade into domain compromise (on-prem ↔ M365) By CyberDudeBivash — Cybersecurity & AI

-
Image
  Executive summary CVE-2025-53786 is a post-authentication elevation of privilege in Microsoft Exchange hybrid deployments . If an attacker first gains admin on an on-prem Exchange server , they can abuse the legacy “shared service principal” trust used by Hybrid Configuration to escalate into Exchange Online —potentially leading to full cloud+on-prem domain compromise . CISA issued Emergency Directive ED-25-02 with a deadline of 9:00 a.m. EDT on August 11, 2025 for U.S. federal agencies; Microsoft urges all hybrid customers to take the same steps: apply the April 2025 Hotfix Updates , migrate to the dedicated Exchange Hybrid app , and reset/clean up service principal credentials . cisa.gov +1 TECHCOMMUNITY.MICROSOFT.COM +1 Why this is dangerous: actions initiated from the on-prem Exchange side may not show up as obviously malicious in M365 audit trails, making cloud abuse harder to spot if you’ve not modernized the trust.
