Fancy Bear's Anatomy: Tactics, Techniques & Procedures

Uploaded on 2025-07-19 in TECHNOLOGY--Hackers, NEWS-Cybersecurity News, INTELLIGENCE-Hot Spots-Russia, FREE TO VIEW

A recent report by the leading cyber threat intelligence firm, Cyfirma, provides an in-depth analysis of Fancy Bear, also known as APT28, a Russian state-sponsored cyberespionage group notorious for its sophisticated cyber attacks.

Active since 2007, Fancy Bear has targeted governments, military organisations, and high-value entities worldwide, driven by motives of espionage, political influence, and reputational damage.

The report, published on 16 July 2025, details the group’s tactics, techniques, and procedures (TTPs), highlighting their evolving strategies and ongoing focus on geopolitical objectives, particularly in relation to the war in Ukraine.

A Prolific Threat Actor

Fancy Bear, also referred to by aliases such as APT28, Sofacy, Strontium, and Pawn Storm, is believed to be linked to Russia’s GRU (Main Intelligence Directorate), specifically units 26165 and 74455. The group has a long history of high-profile cyberattacks, including attempts to influence elections in the United States, France, and Germany.

Notably, Fancy Bear was implicated in the 2016 Democratic National Committee (DNC) hack, which aimed to disrupt the U.S. presidential election through the theft and dissemination of sensitive communications.

Their operations span multiple sectors, including aerospace, defence, energy, media, and critical infrastructure, targeting countries such as Afghanistan, Brazil, France, Germany, Ukraine, and the United States.

Sophisticated Tactics & Techniques

Fancy Bear’s TTPs align with the MITRE ATT&CK framework, showcasing their advanced capabilities. Their primary method of initial access is spear-phishing, using highly tailored emails with malicious attachments or links to spoofed login pages. These phishing campaigns often mimic legitimate sources, such as Ukrainian news outlets or government documents, to increase their effectiveness.

The group also exploits vulnerabilities in public-facing applications, such as webmail platforms like Roundcube and Zimbra, to execute malicious code. Additionally, Fancy Bear employs widespread password-spraying attacks, leveraging Kubernetes clusters to conduct brute-force attacks on weak passwords, particularly targeting Microsoft cloud services.

Malware Arsenal & Exploitation

Fancy Bear’s malware portfolio is extensive, including tools like Zebrocy, Sofacy, X-Agent, CHOPSTICK, Drovorub, and GooseEgg. These are often deployed to steal sensitive data, maintain persistent network access, and facilitate lateral movement. A notable recent campaign involved the exploitation of a Microsoft Outlook vulnerability (CVE-2023-23397) to steal NTLM hashes, enabling further network compromise. The group has also targeted the Windows Print Spooler service, deploying the GooseEgg malware to gain elevated privileges on systems, particularly those in governmental organisations, NGOs, and the education and transportation sectors across Ukraine, Western Europe, and North America.

Geopolitical Objectives & Disinformation

The group’s primary motivation remains intelligence gathering to support Russian geopolitical interests, with a particular focus on the ongoing war in Ukraine. Fancy Bear has targeted Ukrainian officials and military suppliers to gain insights into supply chains and broader conflict-related intelligence. Beyond espionage, the group is known for creating online personas, such as Guccifer 2.0 and Fancy Bears’ Hack Team, to disseminate stolen information and sow disinformation.

These efforts aim to deflect blame and manipulate public perception, aligning with Russia’s broader political agenda.

Recent Campaigns & Global Impact

Recent operations show Fancy Bear’s continued focus on Ukraine and Western entities supporting it. In 2025, the group intensified attacks on logistics and IT firms aiding Ukraine, using spear-phishing, credential-guessing, and exploits against Microsoft Exchange vulnerabilities.

A joint advisory from 21 intelligence agencies across 11 nations, including the UK and U.S., highlighted these attacks, noting Fancy Bear’s compromise of private IP cameras at border crossings and military installations to monitor material movements. Additionally, the group’s use of the Authentic Antics malware to target Microsoft 365 Outlook for credential theft underscores their evolving toolkit.

Defensive Measures & Recommendations

Cyfirma's report emphasises the need for robust cybersecurity measures to counter Fancy Bear’s threats. Organisations should prioritise endpoint detection and response (EDR), security information and event management (SIEM), and security orchestration, automation, and response (SOAR) systems. Regular patching, multi-factor authentication, and employee training to recognise phishing attempts are critical. The report also advocates for attack surface management and unified threat management strategies to mitigate risks from Fancy Bear’s sophisticated campaigns.

A Persistent Global Threat

Fancy Bear remains one of Russia’s most prolific cyber threats, with a track record of high-impact attacks and an ever-evolving arsenal.

As geopolitical tensions, particularly around Ukraine, continue to drive their operations, organisations worldwide must remain vigilant. Cyfirma’s insights emphasise the importance of proactive defence strategies to safeguard against this formidable adversary.
