“Conflitti Digitali: Classificazione e Retroscena” is an article written for a seminar to which the author has participated as speaker. The text is very discursive and examines the evolution of a new way of thinking about the offense: the wars in the cyber space and their backstory. For now, the text is available in italian only...

This evening I received an email with an attached zip. This email was very well made and my anti-virus did not detect anything dangerous -_- veeeery nice…i decided to take a look and see what strange monster was inside :] The executable is a trojan/downloader packed with something custom! After recovering the original executable bypassing all protections, i was able to have a look within it and immediately i saw some interesting functions … [Read more]
To quickly summarize: there has not been an anti-malware solution that was effectively able to avoid the infection of the system or to prevent the privileges escalation put into play. None of the tested solutions was also able to alert the user about an abnormal behavior of our executable. Stop! That’s all ! Further details: The malware is a P2P (D)DoS agent written in pure C by Emanuele De Lucia with TCP SYN and HTTP Flood capabilities, named “apt.exe”. This is basically a dropper. It’s … [Read more]
This script allows to test a full /24 subnet for OpenSLL TLS HeartBeat (HeartBleed) Vulnerability. Originally coded by Jared Stafford ([email protected]) to test this weakness on a single host at a time, it has been modified by Emanuele De Lucia to allow the scan of an entire subnet. This modification has been made for work reasons within few hours by the notice of the vulnerability, in order to readily identify the affected services within a very wide range of systems exposed. May be … [Read more]
Thousands and thousands of data items currently are riding the Internet every day; their representation could be a continuous stream of data transiting through the entire globe. With the growth in quantity and especially in the importance of such informations, the need to adopt systems designed to guarantee a good level of protection and security has also grown in proportion. This paper explores those that are the common steganographic algorithms used to hide informations within seemingly … [Read more]
Reb October is the name of a cyber-espionage toolkit discovered by Kaspersky Lab. The malware was operating worldwide for up to 5 years before to be discovered, transmitting to its C&C servers a lot of informations. Red October is considered an advanced cyber-espionage campaign intended to targeting diplomatic, governmental and financial organizations. This is an analysis conducted by me on 01/13 for InfoSec Institute but published but published after a little... It's possible to view my … [Read more]
SANS DFIRCON is a challenge where we have to download a memory image from SANS and perform over it a complete forensic analysis in order to find the real chinese APT hidden inside and so to answer to five questions about it; These questions may be very similar to: What's the PID of the rogue process ? How is the malware achieving persistence on the system ? What is the name of the file that caused the infection of the system ? If you think to be able to answer, download the image and hunt the … [Read more]
The paper considers the new Internet Protocol (IPv6 or IPng) that is about to replace the old IPv4. The arguments come from reading some texts about it, with a point of view to security that is expected. It also quickly shows the possible evolution of today's most common cyber attacks, as well as some technical details about the suite of IPSec protocols, because its security model will be required to be supported by all IPv6 implementations. It's possible to read this document on GoGo6.com … [Read more]
Hakin9 IT Security Magazine published an article of mine about a practical approach to (D)DoS attacks. In this paper are showed several offensive practices on how to conduct a DDoS attack, with a strong hand on techniques, tools and code chunks. There are also present screenshots and link references to the authors of the various exploits used (when used), as well as even a simple client-server C SYN Flood program created by me in order to better explain how botnets work... Look it on Hakin9 … [Read more]
The following paper takes into consideration those that are the most common methods to prevent or to render unreliable the techniques used for forensic analysis applied to magnetic media in order to gather useful 'evidences' for a computer crime related investigation. The research is focused on topics like data hiding, data obfuscation, encryption, code injection and also online anonymity.
