There are many ways to spot Advanced Persistent Threats, for example during a forensic analysis on “high rate incident” or having sandbox systems on critical infrastructures or again working as incident responder for big companies, working into a national CERT or building a simple tool performing analysis on Malware streams. Today I’d like to share […]
Read more "Free Tools: Spotting APTs"A .CSV file could be a malware carrier and if interpreted by Microsoft Excel it could become a malware executor ! When I personally saw this technique back in 2017 (please take a look to here, here and here ) I was fascinated. A simple and sweet textual file forcing the behaviour of powerful and […]
Read more "Spreading CSV Malware over Google Sheets"Today I’d like to share an interesting analysis of a Targeted Attack found and dissected by Yoroi (technical details are available here). The victim was one of the most important leader in the field of security and defensive military grade Naval ecosystem in Italy. Everything started from a well crafted email targeting the right office […]
Read more "MartyMcFly Malware: Targeting Naval Industry"Today I’d like to share a simple analysis based on fascinating threat that I like to call Sustes (you will see name genesis in a bit). Everybody knows Monero crypto currency and probably everybody knows that it has built upon privacy, by meaning It’s not that simple to figure out Monero wallet balance. Sustes (mr.sh) is […]
Read more "Sustes Malware: CPU for Monero"Machine learning (ML) is a great approach to detect Malware. It is widely used among technical community and scientific community with two different perspectives: Performance V.S Robustness. The technical community tries to improve ML performances in order to increase the usability on large scale while scientific community is focusing on robustness by meaning how easy […]
Read more "Attacking Machine Learning Detectors: the state of the art review"Today I’d like to share another interesting analysis made by my colleagues and I. It would be a nice and interesting analysis since it targeted many Italian and European companies. Fortunately the attacker forgot the LOG.TXT freely available on the dropping URL letting us know the IP addresses who clicked on the first stage analysed […]
Read more "DMOSK Malware Targeting Italian Companies"Today I’d like to share an interesting (at least to me) analysis on a given sample. I have called this sample MalHide but you will see “why” only at the end of my post :D. I believe this is a quite interesting Malware since it firstly implements several obfuscation stages by using different obfuscation techniques […]
Read more "MalHide: an interesting Malware sample"Nowadays is hard to give strong definitions on what are the differences between Security Operation Centers (SOC), Computer Emergency Response Teams (CERT) and Computer Security Incident Response Teams (CSIRT) since they are widely used in many organisations accomplishing very closed and similar tasks. Robin Ruefle (2007) on her paper titled “Defining Computer Security Incident Response […]
Read more "CERTs, CSIRTs and SOCs after 10 years from definitions"Understanding the real code behind a Malware is a great opportunity for Malware analysts, it would increase the chances to understand what the sample really does. Unfortunately it is not always possible figuring out the “real code”, sometimes the Malware analyst needs to use tools like disassemblers or debuggers in order to guess the real […]
Read more "Control Flow Integrity: a Javascript Evasion Technique"On January 18 a colleague of mine (Luca) called me telling a malicious email was targeting Italian companies. This is the beginning of our new analysis adventure that Luca and I run together. The email pretended to be sent by “Ministero dell’ Economia e delle Finanze” the Italian Department of Treasury and it had a […]
