What is APT28?

Uncovering APT28: Examining the Threats and Tactics of One of the World's Most Intrusive Cyber Espionage Groups

APT28, also known as Fancy Bear, Sofacy, PawnStorm and Strontium, among others, is a highly sophisticated state-sponsored group engaged in cyber espionage and considered to be operative since approximately 2007. Providing it various aliases is a common practice on the part of cyber-security firms aiming to make it more relatable and easier to distinguish amid countless other cyber threats. more important than its multiple aliases is the reputation of APT28 as an advanced persistent threat (APT), one of the most horrendous terms in the fright-inducing vocabulary of cybersecurity experts.

APT groups, just like APT28, tirelessly operate in the shadows and are associated with state-sponsored activities. They thrive on their ability to maintain a degree of invisibility while continuously and systematically siphoning off data over an extended period of time. Persistent also characterizes their working methodology as they relentlessly attempt to infiltrate a system until they succeed.

APT28 specifically, is believed to be backed by the Russian government and it has been linked with a series of high-profile cyber-attacks against military, government, media, and non-governmental organizations worldwide. The trend of these attacks suggests a strong inclination towards entities located in countries with whom Russia has ongoing political tensions and conflicts. Often their attacks have had a political purpose, raising more questions about whether cyber space is being used as an arena for interstate rivalry and to achieve strategic geopolitical objectives.

The group uses custom-built advanced malware and exploits zero-day vulnerabilities - security lapses unknown to the developer of the software until it is exploited by an attacker. One highly remarkable zero-day exploit attributed to APT28 targeted the Windows Operating System on machines worldwide, leaving tens of millions of computers vulnerable, one among many evidence of their malignant capabilities.

Even antivirus software has proven inadequate against APT28 attacks due to the suite of evolving capabilities APT28 reflects in its operations, emanating from its heavy investment in cyber espionage. Antivirus software works by detecting known threats based on virus signatures. APTs like APT28 have a knack of continuously creating new, unknown malware types rendering traditional antivirus mechanisms ill-equipped.

To prevent falling prey to groups like APT28, firms require more sophisticated solutions that not only defend against known threats, but also possible unknown threats, akin to the continuously evolving threat vectors exploited by APT28. These measures range from robust firewalls, host-based and network-based intrusion detection and prevention systems (IDS/IPS), to network segmentation, user behavior analytics and incident response systems among, other advanced defense mechanisms.

Investing in cybersecurity hygiene measures such as regular software updates, employing stringent access controls, providing employee awareness training about the nature of sophisticated phishing attempts, are also necessary to thwart APT28-like threats. Given the complexity, organisations often turn to cybersecurity specialists for comprehensive solutions.

At the intersection of technology, defense, politics, and even possibly warfare, APT28 sets an exemplar for the rising prominence of state sponsored cyber espionage groups. As cyber kingpins such as APT28 continue to relentlessly operate in the shadows, the need for vigorous cybersecurity measures, enhanced threat intelligence, international cyber warfare conventions and heightened public awareness rises invariably.
