What are Advanced Persistent Threats?
An Advanced Persistent Threat (APT) is a malicious actor who possesses extraordinary skill and resources. This enables them to infiltrate and exfiltrate an organizations’ network. APTs use a variety of techniques, tactics, and tools—such as highly-targeted social engineering attacks, ransomware, vulnerability exploits, and zero-days to accomplish their illicit objectives.
While some threat actors work alone, multiple government authorities such as the Cybersecurity and Infrastructure Security Agency (CISA) have linked attacks to APT groups. Several of these groups have ties to specific nation-states who use them to further their country’s interests.
How do Advanced Persistent Threat groups operate?
Advanced Persistent Threat groups, as well as those sponsored by a nation-state, aim to gain undetected access to a network. They then remain silently persistent, establish a backdoor, and/or steal data, as opposed to causing damage. Once inside the target network, APTs leverage malware to achieve their directives, which may include acquiring and exfiltrating data.
Where are APTs located?
Here is a collection of Flashpoint’s coverage of known APT groups and other state-sponsored hacking groups:
Russia: Fancy Bear, GRU, FSB, Conti, and more

Within the realm of digital warfare, the threat actor group known as “Killnet” has established itself as a high-visibility force. Emerging as one of the most active and ambitious pro-Kremlin hacktivist collectives, Killnet’s volatility has intensified since the onset of Russia’s invasion of Ukraine over a year ago.
While Killnet demonstrates persistence, it is also notably fickle. The group constantly seeks new avenues for expansion, evolving their tactics, and capturing attention using what they proclaim as their “army of cyber partisans” and the pro-Kremlin media eager to deliver storylines that align with the narrative of the Russian government. Alongside their pursuit of financial gain, Killnet’s notorious alignment with pro-Kremlin ideological motives has fueled their collective drive since the inception of the Russia-Ukraine conflict.
Understanding the inner workings of a prominent group like Killnet becomes vital for organizations aiming to grasp the broader cyber threat landscape. By unraveling the operations of Killnet, organizations can bolster their understanding and fortify their defenses against this evolving menace.
