Overview
Fancy Bear, aka APT28, is a globally ill-famed Russian cyberespionage group known for attacks on governments, military entities, and high-value targets. Operational since 2007, it has executed several well-coordinated, stealthy attacks, etching its presence into the history of cybersecurity. As per various reports, the attacker group has attempted to influence election processes in the U.S., France, and Germany, and was also behind the 2017 NotPetya attack.
Over the past 20 months, Fancy Bear has been in the news for exploiting a Microsoft Outlook bug, targeting over two dozen organizations across 14 nations that are deemed strategically significant to the Russian government and its military. The threat group’s covert operations are aimed at achieving long-term infiltration of their targets’ systems. With that said, let’s quickly dive into its attack techniques.
Tactics, Techniques, and Procedures
Fancy Bear often uses targeted spearphishing campaigns to deliver malicious payloads where it camouflages itself as emails from a trusted source. The group is also known for exploiting security flaws in software, including zero days. This year, Fancy Bear made headlines for exploiting Outlook zero-day (CVE-2023-23397), an RCE vulnerability in Cisco Routers (CVE-2017-6742), and a WinRar flaw (CVE-2023-38831). (More details are shared in the next section.)
In general, the group employs a diverse array of advanced techniques and tactics to carry out malicious operations that directly or indirectly benefit Russia.
- Malware Attacks: The group uses various types of malware, including custom-built tools. Sofacy, X-Agent, Sednit, and Zebrocy are among the malware associated with APT28.
- Watering Hole Attacks: APT28 has been known to compromise websites likely to be visited by their targets. This tactic involved injecting malicious code into those websites.
- Credential Theft: APT28 employs techniques to steal credentials, such as using keyloggers or credential harvesting tools, to gain access to systems and networks.
- Persistence Mechanisms: APT28 uses various methods to maintain access to compromised systems for an extended period. This may involve creating backdoors, using scheduled tasks, or manipulating system services.
- Domain Registration and Infrastructure: APT28 is known to register domains that mimic legitimate ones, creating a deceptive infrastructure for their operations.
- Use of Virtual Private Servers (VPS): The group often uses VPS providers to host their command and control (C2) servers, helping to hide their tracks and make attribution more challenging.
- Geopolitical Targeting: APT28's campaigns often align with geopolitical events, suggesting that the group operates in support of Russian state interests.
Attack Details
Espionage-motivated Fancy Bear has targeted Eastern European governments, military entities, Georgia, Ukraine, and organizations like NATO, along with U.S. defense contractors such as Academi, SAIC, Boeing, Lockheed Martin, and Raytheon.
Fancy Bear's target list from March 2015 to May 2016 encompassed a wide range of individuals opposing Putin and the Kremlin in the U.S., Ukraine, Russia, Georgia, and Syria, including both Democratic and Republican entities.
To trace Fancy Bear’s journey to notoriety, below are the incidents that it was involved in:
- French TV Station TV5 Monde (2015): In April 2015, Fancy Bear destroyed the internet-connected hardware that controlled France's TV5 Monde TV station’s operations. They also hijack the website and social media accounts.
- U.S. Presidential Election Attack (2016): Fancy Bear targeted Democratic National Committee (DNC) email servers, and stole sensitive emails and other information that were later leaked to the public. It is seen as an attempt to influence the 2016 presidential elections.
- German Bundestag (2017): The group was publicly associated with infiltrating the German Bundestag, employing spear-phishing attacks and malware to compromise government officials and expand network access.
- NotPetya Malware Attack (2017): In 2017, Fancy Bear was connected to the destructive NotPetya malware attack that would go on to do $10 billion worth of loss globally, with other significant damages to impacted organizations.
- Worldwide Anti-doping Agency (2017): Fancy Bear was linked to hack-and-leak operations against the Worldwide Anti-doping Agency, seen as retaliation for Russia's ban from the 2018 Winter Olympics. Ahead of the Tokyo 2020 Olympics, adversaries targeted at least 16 national and international organizations across three continents.
- Brute-Force Attacks: U.S. and U.K. authorities warned of Fancy Bear's widespread campaign ongoing since mid-2019. The attack utilizes a Kubernetes cluster for brute-force password-spraying attacks against numerous global government and private sector targets.
Espionage in 2022-23
Ukraine and NATO Countries
The Ukraine-Russia conflict unveiled a new chapter of cyberattacks between nations, with APT28 at the forefront of this cyber war. According to Palo Alto’s Unit 42 researchers, the group used the Outlook bug exploit for over 20 months in 14 nations that were of strategic intelligence value to the Russian government. The group conducted the attack campaigns in three parts, with the latest occurring in December 2023. Its attacks focused on critical infrastructure and energy-related entities, pipeline operations, government ministries, and more in NATO member countries. Outside NATO allies, Ukraine, Jordan, and the UAE were its targets. All in all, at least 30 organizations were affected by the attacks.
Fancy Bear’s attacks on Ukraine are nothing new; several attack campaigns have been launched against Ukraine since 2014. From 2014 to 2016, the threat actor dominantly distributed the X-Agent malware implant on Ukrainian military forums bundles with a legitimate application employed by Ukrainian artillery forces to collect tactical data.
Cisco Routers Abused
In April, Fancy Bear members exploited an RCE vulnerability (CVE-2017-6742) in Cisco routers' SNMP implementation. A joint advisory by Western security agencies revealed that actors used this tactic to backdoor Cisco routers globally, including in Europe, US government institutions, and approximately 250 Ukrainian victims.
Israel-Hamas War
Security experts uncovered an attack campaign by Fancy Bear, in December, using lures related to the ongoing Israel-Hamas war to deliver a custom backdoor called HeadLace. The campaign targeted critical infrastructure organizations across Hungary, Turkey, Australia, Poland, Belgium, Ukraine, Germany, Azerbaijan, Saudi Arabia, Kazakhstan, Italy, Latvia, and Romania. The infection chain exploited a WinRAR flaw called CVE-2023-38831 to propagate the backdoor.
Preventive Measures
First and foremost, governments and critical infrastructure providers across NATO and European nations are urged to patch the Outlook bug. Microsoft has issued guidance to help identify attacks exploiting the bug. In addition to that, security teams must configure endpoint protections to restrict such malicious campaigns.
Additionally, organizations that leverage strategic and tactical threat intelligence to sharpen their detection and response measures and collaborate beyond their operational silos are likely to defend more effectively against threat actors like Fancy Bear. Cyware’s Intel Exchange (CTIX), Orchestrate, and Respond (CFTR) platforms empower organizations through threat intel automation and advanced threat analysis, while also promoting effective security collaboration and building a proactive defense against sophisticated cyberattacks.
Conclusion
Fancy Bear has remained a persistent and enigmatic adversary for over a decade. By delving into their tactics, motivations, and complex operations, we gain the insights necessary to counter their ambitions. Their adaptability and innovation present a formidable challenge to both governments and organizations globally. Defending against Fancy Bear mandates continuous enhancement and adaptation of state-of-the-art defensive strategies.
