Understanding Malware Propagation Dynamics through Scientific Machine Learning

Accurately modeling malware propagation is essential for designing effective cybersecurity defenses, particularly against adaptive threats that evolve in real time. While traditional epidemiological models and recent neural approaches offer useful foundations, they often fail to fully capture the...

Largest DDoS Attack to Date

It was a recently unimaginable 7.3 Tbps: The vast majority of the attack was delivered in the form of User Datagram Protocol packets. Legitimate UDP-based transmissions are used in especially time-sensitive communications, such as those for video playback, gaming applications, and DNS lookups. It...

NTP Aplification, SYN Floods Drive Up DDoS Attack Volumes

There has been a steady but dramatic increase in the potency of distributed denial of service DDoS attacks from the beginning of 2013 through the first two months of this year. In large part, reason for this rise in volume has to do with the widespread adoption of two attack methods: large...

Kerberos Server Spoofed Packet Amplification DoS (PingPong)

The remote host is running a Kerberos server that seems to be vulnerable to a 'ping-pong' attack. When contacted on the UDP port, this service always responds, even to malformed requests. This makes it possible to involve it in a 'ping-pong' attack, in which an attacker spoofs a packet between tw...

Quote of the Day (QOTD) Service Detection

A server listens for TCP connections on TCP port 17. Once a connection is established a short message is sent out the connection and any data received is thrown away. The service closes the connection after sending the quote. Another quote of the day service is defined as a datagram based...

Chargen UDP Service Remote DoS

When contacted, chargen responds with some random characters something like all the characters in the alphabet in a row. When contacted via UDP, it will respond with a single UDP packet. When contacted via TCP, it will continue spewing characters until the client closes the connection. The purpos...
