Online criminals don’t fit into a neat box – they’re as varied as their targets. Some want quick cash through ransomware, others are nation-state hackers playing a long game of digital espionage. A few might even hack just to prove…
Catching hidden command-and-control (C2) signals isn’t simple. Attackers mask their moves, blending bad traffic with the usual, so spotting them takes sharp eyes. Watch for odd DNS queries, strange traffic flows, and weird system actions, these clues can reveal secret…
Malware’s command-and-control (C2) behavior can’t be fully understood just by looking at its code. Sandboxing steps in as a way for security teams to watch malware in action, safely. It’s not just about running suspicious files in a locked-down space,…
Command-and-control domains, or C2 domains, are where many cyber attacks begin. They let hackers talk to infected computers, send orders, and steal data. Finding these domains isn’t easy, but it’s very important to stop attacks early. By watching network traffic…
C2 over HTTPS challenges hides bad traffic inside normal-looking, encrypted web data, making it really hard to spot. Attackers use real TLS certificates and act like regular web users to avoid suspicion. Since HTTPS encrypts everything, security tools can’t see…
Fast flux DNS Detection networks might slip through the cracks of simple DNS checks because they constantly shuffle IP addresses and tweak DNS records to stay hidden. Detecting them means paying close attention to patterns like how often TTL values…
Cutting off command and control (C2) servers means stopping hackers from taking over infected computers and stealing data. These servers secretly send commands and collect stolen information. Blocking their IP addresses can slow or even stop malware from spreading. But…
C2 beaconing patterns are signals attackers use to communicate with control centers. They rely on timing between messages, packet size, and target sites, often disguising C2 beacons through encryption or by mimicking normal traffic. Attackers use regular timing with slight…
The dark corners of cybersecurity’s command and control networks (C2) expose a whole ecosystem where good and bad actors play out their battles daily. Red teams can’t just pick up or and expect magic – there’s real skill behind running…
Capturing the essence of identifying domain generation algorithms (DGA) involves understanding how malware uses these methods to communicate securely. DGAs churn out countless domain names daily, serving as rendezvous points for command-and-control (C2) servers. Since most generated domains stay unregistered,…
