APT29 SpearPhishing Europe: A Stealthy LongTerm Threat

APT29 spearphishing Europe campaigns highlight a persistent and highly sophisticated cyberespionage threat orchestrated by Russia’s Foreign Intelligence Service (SVR), known as Cozy Bear. Active since at least 2008, APT29 has become synonymous with stealthy operations targeting European institutions through phishing emails, Microsoft 365 abuse, supply chain compromises, and persistent malware implants. Unlike APT28’s aggressive tactics, APT29’s approach is patient, subtle, and highly strategic—favoring covert surveillance over immediate disruption. This article examines APT29’s tactics, European targeting strategy, technical indicators, and how sovereign solutions like DataShielder and PassCypher help organizations defend against Russian longterm cyber espionage campaigns.

APT29’s Persistent Espionage Model: The Art of the Long Game in Europe

APT29’s operational model is defined by stealth, longevity, and precision. Their goal is not shortterm chaos but sustained infiltration. Their campaigns frequently last months—or years—without being detected. APT29 rarely causes disruption; instead, it exfiltrates sensitive political, diplomatic, and strategic data across Europe.

APT29 often custombuilds malware for each operation, designed to mimic legitimate network activity and evade common detection tools.

Covert Techniques and Key Infiltration Methods

APT29’s longterm access strategy hinges on advanced, covert methods of penetration and persistence:

Custom Backdoors

Backdoors like “WellMess” and “WellMail” use encrypted communications, steganography, and cloud services to evade inspection. They also include antianalysis techniques such as antiVM and antidebugging code to resist forensic examination.

Supply Chain Attacks

The SolarWinds Orion attack in 2020 remains one of the largest breaches attributed to APT29. This compromise of the supply chain allowed attackers to infiltrate highvalue targets via trusted software. The SUNBURST and TEARDROP implants enabled stealthy lateral movement.

SpearPhishing from Compromised Diplomatic Sources

APT29’s phishing operations often originate from hijacked diplomatic email accounts, lending legitimacy to phishing attempts. These emails target government bodies, international organizations, and embassies across Europe.

Credential Harvesting via Microsoft 365

APT29 abuses cloud infrastructure by executing OAuth consent phishing, targeting legacy authentication protocols, and compromising user credentials to access SharePoint, Outlook, and cloudstored documents.

GRAPELOADER and WINELOADER: New Malware Lures in 2025

In April 2025, APT29 launched a phishing campaign dubbed SPIKEDWINE, impersonating a European Ministry of Foreign Affairs and inviting victims to fake winetasting events. These emails, sent from domains like bakenhof[.]com and silry[.]com, delivered malware via a file named “wine.zip.”

The attack chain begins with GRAPELOADER, a previously undocumented loader, followed by a new variant of the WINELOADER backdoor. This multistage infection shows evolving sophistication in malware design, timing of payload execution, and evasion techniques. The campaign’s targets include multiple European Ministries of Foreign Affairs and nonEuropean embassies in Europe.

Geopolitical Implications of APT29’s European Operations

APT29’s spear-phishing activities are not just technical threats—they are instruments of Russian geopolitical strategy. The group’s consistent targeting of ministries, embassies, and think tanks across Europe aligns closely with key diplomatic and policy moments.

APT29’s operations often intensify ahead of European elections, EU-NATO summits, or major sanctions announcements. Their goal is not only to steal sensitive intelligence, but to subtly influence policymaking by gaining access to classified assessments, private negotiations, or internal dissent.

Notable examples include:

APT29 acts as a digital vanguard for Russian hybrid warfare, where cyber operations feed into diplomatic leverage, information warfare, and strategic disruption. Understanding this broader agenda is crucial for shaping European cyber defense beyond the technical dimension.

European Government Responses to APT29: A Patchwork Defense

This comparison illustrates the fragmented nature of Europe’s institutional responses to state-sponsored cyber threats. While some nations have clearly identified and named APT29, others remain more cautious or reactive.

What if APT29 Had Not Been Detected?

While some operations were eventually uncovered, many persisted for months or years. Had APT29 remained entirely undetected, the implications for Europe’s political and strategic landscape could have been far-reaching:

  • Diplomatic Blackmail: With access to confidential negotiations, APT29 could have leaked selective intelligence to disrupt alliances or blackmail key figures.
  • Policy Manipulation: Strategic leaks before elections or summits could steer public opinion, weaken pro-EU narratives, or stall collective defense decisions.
  • NATO Cohesion Threats: Exfiltrated defense policy data could be used to exploit divisions between NATO member states, delaying or undermining unified military responses.
  • Influence Campaign Fuel: Stolen data could be recontextualized by Russian disinformation actors to construct persuasive narratives tailored to fracture European unity.

This scenario highlights the necessity of early detection and sovereign countermeasures—not merely to block access, but to neutralize the geopolitical utility of the exfiltrated data.

Notable APT29 Incidents in Europe

Date Operation Name Target Outcome
2015 CozyDuke U.S. & EU diplomatic missions Long-term surveillance and data theft
2020 SolarWinds EU/US clients (supply chain) 18,000+ victims compromised, long undetected persistence
2021–2023 Microsoft 365 Abuse EU think tanks Credential theft and surveillance
2024 European Diplomatic Ministries in FR/DE Phishing via embassy accounts; linked to GRAPELOADER malware
2025 SPIKEDWINE European MFA, embassies GRAPELOADER + WINELOADER malware via wine-tasting phishing lure

APT28 spear-phishing France: a persistent pan-European threat

⮞ Résumé. Depuis 2021, APT28 intensifie des campagnes de spear-phishing centrées sur Outlook contre des institutions françaises et européennes. Le groupe combine vol d’identifiants « zero-click » (CVE-2023-23397), accès de courte durée et exfiltration furtive, réduisant la fenêtre de détection. Priorité : monitoring comportemental et canaux HSM souverains.

APT28 spear-phishing France now represents a critical digital security challenge on a European scale. Since 2021, several European states, including France, have faced an unprecedented intensification of spear-phishing campaigns conducted by APT28, a state-sponsored cyber-espionage group affiliated with Russia’s GRU. Also known as Fancy Bear, Sednit, or Sofacy, APT28 targets ministries, regional governments, defense industries, strategic research institutions, critical infrastructure, and organizations involved with the Paris 2024 Olympic Games. This analysis details an APT28 Outlook backdoor pathway and defensive countermeasures.

In a tense geopolitical context across Europe, APT28’s tactics are evolving toward stealthy, non-persistent attacks using malware like HeadLace and exploiting zero-day vulnerabilities such as CVE-2023-23397 in Microsoft Outlook. This vulnerability, detailed in a CERT-FR alert (CERTFR-2023-ALE-002), allows an attacker to retrieve the Net-NTLMv2 hash, potentially for privilege escalation. It is actively exploited in targeted attacks and requires no user interaction, being triggered by sending a specially crafted email with a malicious UNC link. This trend mirrors tactics used by APT44, explored in this article on QR code phishing, underscoring the need for sovereign hardware-based tools like DataShielder and PassCypher. European CISOs are encouraged to incorporate these attack patterns into their threat maps.

Historical Context: The Evolution of APT28

APT28 (Fancy Bear) has been active since at least 2004, operating as a state-sponsored cyber-espionage group linked to Russia’s GRU. However, its most heavily documented and globally recognized operations emerged from 2014 onward. That year marks a strategic shift, where APT28 adopted more aggressive, high-visibility tactics using advanced spear-phishing techniques and zero-day exploits.

Between 2008 and 2016, the group targeted several major geopolitical institutions, including:

• The Georgian Ministry of Defense (2008)
• NATO, the White House, and EU agencies (2014)
• The U.S. presidential election campaign (2016)

This period also saw extensive exposure of APT28 by cybersecurity firms such as FireEye and CrowdStrike, which highlighted the group’s growing sophistication and its use of malicious Word documents (maldocs), cloud-based command-and-control (C2) relays, and coordinated influence operations.

These earlier campaigns laid the foundation for APT28’s current operations in Europe — especially in France — and illustrate the persistent, evolving nature of the threat.

Priority targets for APT28 spear-phishing campaigns

Target typology in APT28 campaigns

APT28 targets include:

  • Sovereign ministries (Defense, Interior, Foreign Affairs)
  • Paris 2024 Olympics organizers and IT contractors
  • Operators of vital importance (OIVs): energy, transport, telecoms
  • Defense industrial and technological base (BITD) companies
  • Research institutions (CNRS, INRIA, CEA)
  • Local governments with strategic competencies
  • Consulting firms active in European or sensitive matters

Historical Context: The Evolution of APT28

APT28 (Fancy Bear) has been active since at least 2004, operating as a state-sponsored cyber-espionage group linked to Russia’s GRU. However, its most heavily documented and globally recognized operations emerged from 2014 onward.

Spear-phishing and electoral destabilization in Europe

⮞ Summary. Technical intrusions are synchronized with influence campaigns around elections and summits. Goal: erode trust in institutions and shape decision-making through leaks and narrative amplification.

Political and geopolitical context of APT28 campaigns

APT28’s campaigns often precede key elections or diplomatic summits, such as the 2017 French presidential election, the 2019 European elections, or the upcoming Paris 2024 Olympic Games. These are part of a broader hybrid strategy aimed at destabilizing the EU.

Some spear-phishing attacks are synchronized with disinformation operations to amplify internal political and social tensions within targeted nations. This dual tactic aims to undermine public trust in democratic institutions.

Reference: EU DisinfoLab – Russia-backed disinformation narratives

Germany and NATO have also reported a resurgence of APT28 activities, particularly against NATO forces stationed in Poland, Lithuania, and Estonia. This strategic targeting of European institutions is part of a broader effort to weaken collective security in the EU.

Other APT28 campaigns between CVE-2023-23397 and NotDoor

⮞ Summary. Ministries, OIVs, BITD, research bodies and Paris-2024 stakeholders remain top priorities. Consulting firms and local authorities with strategic mandates are leveraged as entry points for lateral movement.

Between the Outlook zero-day CVE-2023-23397 and the emergence of the NotDoor Outlook backdoor, APT28 sustained a steady cadence of precision intrusions. The group leveraged widely deployed enterprise software to deliver APT28 spear-phishing chains at scale, moving from classic maldocs to Outlook-centric compromise and covert exfiltration.

Vulnerability Attack type Target APT28 usage
CVE-2023-38831 Malicious ZIP (WinRAR exploit) Diplomatic & defense sectors Weaponized archives in targeted phishing; payload staging and credential theft
CVE-2021-40444 ActiveX exploit (MSHTML) NATO-linked institutions Malicious Word documents embedding ActiveX to gain initial code execution
CVE-2023-23397 Outlook zero-day Energy & transport operators Zero-click NTLM material theft enabling relay and lateral movement

Takeaway. These campaigns show a tactical progression from maldoc & archive abuse toward Outlook-centric backdoors, culminating with NotDoor’s Outlook VBA macro phishing, DLL side-loading via OneDrive.exe, and Proton Mail covert exfiltration.

NotDoor: a new Outlook backdoor in APT28’s toolchain

⮞ Summary. NotDoor weaponizes Outlook via VBA event hooks, keyword-triggered tasking, OneDrive.exe DLL side-loading and encrypted mail exfiltration. Detections pivot on Outlook child-process chains, macro creation, and anomalous OneDrive module loads.

NotDoor represents a tactical leap in APT28 spear-phishing chains: instead of only abusing delivery vectors, the operators weaponize Microsoft Outlook itself. A malicious VBA macro hooks mailbox events, watches for keyword triggers in new mail, and—on match—executes commands, stages files, and exfiltrates data. This Outlook-centric backdoor blends with daily workflows, reduces telemetry noise, and undermines perimeter detections.

How the backdoor operates

  • Initial foothold: Outlook VBA macro phishing seeded via targeted messages or trust-store abuse (macro-enabled project in the user profile).
  • Mailbox surveillance: event handlers monitor incoming emails for operator tasking (e.g., “Daily Report”, “Timesheet”, summit- or exercise-themed lures).
  • Tasking & execution: the macro launches system commands, enumerates files and mailbox items, compresses artifacts, and uploads follow-on payloads.
  • Defense evasion: DLL side-loading via OneDrive.exe loads a malicious library behind a trusted Microsoft binary to degrade signature-based controls.
  • Covert egress: Proton Mail covert exfiltration camouflages outbound traffic among legitimate encrypted flows.

Where NotDoor fits vs HeadLace & CVE-2023-23397

Capability HeadLace CVE-2023-23397 (Outlook) NotDoor
Primary role Loader / C2 staging Zero-click credential material theft Outlook-resident backdoor (VBA)
Initial trigger Spear-phishing + droppers Crafted Outlook item (MAPI reminder) Mailbox keyword match on new mail
Operator actions Payload delivery, beaconing NTLM relay → lateral movement Command exec, file upload, selective exfiltration
Key evasions Cloud relays; short-lived infra Abuses client processing path OneDrive.exe DLL side-loading; encrypted mail channel
Detections
  • Unusual OUTLOOK.EXE or user apps spawning LOLBins; short-lived staging dirs; cloud beaconing (GitHub/Trello).
  • Outlook items with reminder props pointing to UNC; spikes in external SMB/NTLM after item processing.
  • Outlook macro enable/create events; OUTLOOK.EXE spawning cmd.exe/powershell.exe/wscript.exe; OneDrive.exe loading DLLs from user-writable paths; encrypted egress to privacy providers.

Detection & hunts (behavior-first)

  • Macro exposure: disable Outlook VBA by policy; alert on macro project creation/enable in Office trust stores.
  • Process chains: flag OUTLOOK.EXE spawning script interpreters, archivers, or shells; correlate with mailbox event timing.
  • Side-loading: monitor OneDrive.exe module loads from non-system paths; detect unsigned or unexpected DLLs co-located with it.
  • Mailflow anomalies: DLP/heuristics for sudden encrypted egress to privacy providers from workstation hosts; compressed archives leaving via mail.
  • Keyword intel: hunt for mailbox rules/macros using operational terms (e.g., “report”, “invoice”, exercise names, event code-words).

MITRE ATT&CK mapping (core techniques)

  • T1204 — User Execution: malicious file/macro (Outlook VBA project)
  • T1059 — Command & Scripting Interpreter (cmd/PowerShell/WScript)
  • T1574.002 — Hijack Execution Flow: DLL Side-Loading (OneDrive.exe)
  • T1041 — Exfiltration Over C2 Channel (encrypted mail channel)

Operational hardening (sovereign posture)

  • Harden Outlook (disable macros by default; restrict trusted locations; block unsigned VBA).
  • Instrument Outlook/OneDrive behaviors and alert on risky child-process or module-load patterns.
  • Adopt sovereign email encryption HSM: use DataShielder HSM PGP for end-to-end encryption with volatile-memory decryption only; pair with PassCypher HSM PGP for offline OTP/credential custody.

APT28 attribution and espionage objectives

  • Attribution: Main Intelligence Directorate (GRU), Unit 26165
  • Key techniques: Targeted phishing, Outlook vulnerabilities, compromise of routers and peripheral devices
  • Objectives: Data exfiltration, strategic surveillance, disruption of critical operations

APT28 also coordinates technical operations with information warfare: fake document distribution, disinformation campaigns, and exploitation of leaks. This “influence” component, though less covered in mainstream reports, significantly amplifies the impact of technical attacks.

Observed campaigns and methods (2022–2025)

Date Campaign Targets Impact
March 2022 Diplomatic phishing EU ministries Theft of confidential data
July 2023 Military campaign French and German forces Access to strategic communications
Nov. 2024 HeadLace & CVE exploit Energy sector Risk of logistical sabotage
April 2025 Olympics 2024 operation French local authorities Compromise of critical systems

Mapping APT28 to the Cyber Kill Chain

Kill Chain Step Example APT28
Reconnaissance DNS scanning, 2024 Olympic monitoring, WHOIS tracking
Weaponization Doc Word piégé (maldoc), exploit CVE-2023-23397
Delivery Spear-phishing by email, fake ..fr/.eu domains
Exploitation Macro Execution, Outlook Vulnerability
Installation Malware HeadLace, tunnels cloud (Trello, Dropbox)
C2 GitHub relay, DNS Fast Flux
Actions on Obj. Exfiltration, disinformation coordinated with DCLeaks

Tactics and Infrastructure: Increasing Sophistication

APT28 campaigns are distinguished by a high degree of stealth:

  • Domain spoofing via homographs (e.g. gov-fr[.]net).
  • Real-time payload encryption.
  • Using legitimate cloud services like GitHub, Dropbox, or Trello as a C2 relay.
  • Hosting on anonymized infrastructures (Fast Flux DNS, bulletproof hosting).
  • Non-persistent attacks: ephemeral access, rapid exfiltration, immediate wipe. This approach makes detection particularly complex, as it drastically reduces the window of opportunity for forensic analysis, and the attacker’s infrastructure is often destroyed rapidly after compromise.

This mastery of technical obfuscation makes detection particularly complex, even for the most advanced SIEM systems and EDRs.

ANSSI’s operational recommendations

⮞ Summary. Prioritize patching, macro hardening, behavior analytics on OUTLOOK.EXE/OneDrive.exe, DLP on encrypted egress, and sovereign HSMs for sensitive exchanges and credentials.
  • Apply security patches (known CVEs) immediately.
  • Audit peripheral equipment (routers, appliances).
  • Deploy ANSSI-certified EDRs to detect anomalous behavior.
  • Train users with realistic spear-phishing scenarios.
  • Segment networks and enforce the principle of least privilege.
  • Disable Outlook VBA macros by default via group policy; restrict Office trusted locations; block unsigned macros.
  • Instrument Outlook & OneDrive process behavior: alert on OUTLOOK.EXE spawning script interpreters and on OneDrive.exe loading DLLs from non-system paths.
  • Mailflow controls: DLP/heuristics for unexpected encrypted egress to privacy providers (e.g., Proton Mail) from workstation hosts.
  • Sovereign channeling for sensitive comms: use DataShielder HSM PGP to end-to-end encrypt messages with volatile-memory decryption only; pair with PassCypher HSM PGP for offline OTP/credential custody.
  • Threat hunting: search for anomalous Outlook rules/macros, compressed archives in sent items, and keyword-based mailbox automations.
  • Map NotDoor hunts to MITRE ATT&CK: T1204 (User Execution: Malicious File/Macro), T1059 (Command and Scripting Interpreter), T1574.002 (Hijack Execution Flow: DLL Side-Loading), T1041 (Exfiltration Over C2 Channel).

For detailed guidance, refer to the ANSSI recommendations.

Regulatory framework: French response to spear-phishing

⮞ Summary. LPM, NIS/NIS2 and ANSSI guidance set enforceable baselines for OIV/OES. Compliance pairs with sovereign tooling (HSM, offline segmentation) to reduce exposure to mailbox-centric intrusions.
  • Military Programming Law (LPM): imposes cybersecurity obligations on OIVs and OESs.
  • NIS Directive and French transposition: provides a framework for cybersecurity obligations.
  • SGDSN: steers the strategic orientations of national cybersecurity.
  • Role of the ANSSI: operational referent, issuer of alerts and recommendations.
  • EU-level Initiatives: Complementing national efforts like those led by ANSSI in France, the NIS2 Directive, the successor to NIS, strengthens cybersecurity obligations for a wider range of entities and harmonizes rules across European Union Member States. It also encourages greater cooperation and information sharing between Member States.

Sovereign solutions: DataShielder & PassCypher against spear-phishing

Sovereign solutions: DataShielder & PassCypher against spear-phishing

⮞ Summary. “Zero cloud, zero disk, zero DOM” posture: end-to-end email encryption with volatile-memory decryption (DataShielder) plus offline credential/OTP custody and anti-BITB sandboxing (PassCypher).

DataShielder NFC HSM: An alternative to traditional MFA authentication

Most of APT28’s spear-phishing publications recommend multi-factor authentication. However, this MFA typically relies on vulnerable channels: interceptable SMS, exposed cloud applications, or spoofed emails. DataShielder NFC HSM introduces a major conceptual breakthrough:

These controls provide a sovereign email encryption HSM approach for sensitive exchanges.

Criterion Classic MFA DataShielder NFC HSM
Channel used Email, SMS, cloud app Local NFC, without network
Dependency on the host system Yes (OS, browser, apps) No (OS independent)
Resistance to spear-phishing Average (Interceptable OTP) High (non-repeatable hardware key)
Access key Remote server or mobile app Stored locally in the NFC HSM
Offline use Rarely possible Yes, 100% offline
Cross-authentication No Yes, between humans without a trusted third party

This solution is aligned with a logic of digital sovereignty, in line with the recommendations of the ANSSI.

DataShielder HSM PGP can encrypt all types of emails, including Gmail, Outlook, Yahoo, LinkedIn, Yandex, HCL Domino, and more. It encrypts messages end-to-end and decrypts them only in volatile memory, ensuring maximum privacy without leaving a clear trace.

PassCypher HSM PGP enhances the security of critical passwords and TOTP/HOTP codes through:

  • 100% offline operation without database or server
  • Secure input field in a dedicated tamper-proof sandbox
  • Protection native contre les attaques BITB (Browser-in-the-Browser)
  • Automatic sandbox that checks original URLs before execution
  • Secure management of logins, passwords, and OTP keys in a siloed environment

Sovereign Use Case — Outlook backdoor neutralized

Context. A regional authority receives a themed spear-phish. A VBA project drops into Outlook. The macro watches for “weekly report”.

  1. Before: No macro hardening. OUTLOOK.EXE spawns powershell.exe; OneDrive.exe side-loads DLL; artifacts exfiltrated via encrypted mail to a privacy provider.
  2. With DataShielder: Sensitive threads are end-to-end encrypted; decryption occurs only in volatile memory; exfiltration yields ciphertext with no reusable keys.
  3. With PassCypher: Admin/partner credentials and TOTPs are offline, outside browser/DOM; phishing-induced login prompts fail; anti-BITB sandbox blocks spoofed portals and checks original URLs before input.
  4. Detection: SOC rules flag OUTLOOK.EXE → powershell.exe and OneDrive.exe loading non-system DLLs. DLP alerts on unexpected encrypted egress volume from workstations.
  5. Outcome: Macro tasking is contained; no cleartext data loss; no credential replay; attacker’s window closes within minutes.

Towards a European cyber resilience strategy

⮞ Summary. EU-level coordination (ENISA, CSIRTs), harmonized regulation (NIS2/CRA) and interoperable sovereign HSM stacks are prerequisites to counter mailbox-centric espionage at scale.

APT28, APT29, APT44: these are all groups that illustrate an offensive escalation in European cyberspace. The response must therefore be strategic and transnational:

  • Coordination by ENISA and the European CSIRT Network
  • IOC sharing and real-time alerts between Member States
  • Regulatory harmonization (NIS2 revision, Cyber Resilience Act)
  • Deployment of interoperable sovereign solutions such as DataShielder and PassCypher

What We Didn’t Cover — Next chapters

  • APT29: OAuth app-based persistence and cloud forensics pitfalls.
  • APT31: Credential-phishing against diplomatic targets and router exploitation.
  • APT44: Mobile-first QR-phishing and blended info-ops.
  • Incident response playbooks: mailbox macro triage, OneDrive side-load scoping, encrypted-egress containment.

Weak Signals — Trends to Watch

  • AI-generated lures at scale — Highly tailored spear-phish (meeting minutes, RFPs, summit agendas) produced by LLM pipelines, increasing click-through and bypassing traditional content heuristics.
  • Malicious Outlook add-ins / COM supply chain — Pivot from VBA macros to signed-looking add-ins that survive macro hardening and blend with productivity tooling.
  • OAuth consent phishing & token replay — App-based persistence without passwords; mailbox rules + Graph API automation to emulate “human” inbox behavior.
  • Legacy VPN & SASE bypass — Reuse of stale creds, split-tunnel misconfigs, and coarse geofencing to reach O365/Outlook from “trusted” egress points.
  • Encrypted DNS/DoH for staging — Low-signal C2 bootstrap and selector lookups hidden in privacy traffic; harder to baseline on egress.
  • Deepfake-assisted vishing — Real-time voice cloning to legitimize urgent mailbox actions (“approve macro”, “send weekly report”).
  • QR-code hybrid lures (desktop ↔ mobile) — Convergence with APT44 playbooks; cross-device session hijack and MFA coercion via mobile scanners. See also: APT44 QR code phishing.
  • OneDrive.exe side-loading variants — New search-order tricks and user-writable paths; signed-binary proxying to evade EDR trust gates.
  • SOHO/edge router staging — Short-lived hops and NAT-ed implants to mask operator infrastructure and rotate origins near targets.
  • MFA friction exploits — Push-fatigue + number-matching workarounds; social sequences that time prompts to business rituals (shift changes, on-call handovers).
  • ECH/TLS fingerprint hiding — Encrypted Client Hello + JA3 randomization to degrade domain/SNI-based detections on mailbox-adjacent exfiltration.
