Hi, I’m Syed. Explore my articles as I embark on this journey of learning more about Forensics, Threat Hunting, and Cyber-threat Intelligence.

Shell Links or more commonly known to native Windows users as shortcut files — technically known by their extension LNK — serve to be one of the most fruitful initial access vectors for threat actors. …

Cross-references, or more commonly referred to as xrefs, are used to identify references (usage/call or declaration) of a particular function, string, variable, etc. …

Now that the intelligence community is finally reaching its due maturity, advisories shared with fellow organizations often contain useful detection use-cases. If we were to travel back a few years, an average analyst would dread the manual conversion of these use-cases into searchable queries for the logging platform or SIEM…

Attackers have long been searching for ways to meddle with the day-to-day operations of an average computer user. It’s no wonder the Microsoft Office suite has been one of the key targets of adversaries to compromise endpoints. What better than to dispatch a seemingly-harmless office document to a rather naive…

The article is a write-up for challenge number one — the Web Server Case — by Ali Hadi on his blog, ‘ashemery.com’. The premise is set to:

It does, however, support temporary storage of commands executed in an active session. So, if an attacker proceeds to enumerate other hosts or ex-filtrate data using a console…

Nasty Rootkits hiding in memory? No more!

Ah, the sweet days of running your memory sample through volatility. It’s not over yet — but Microsoft has done an amazing job at releasing a new service, which can perform a full-blown volatile memory analysis of a Linux system, with special focus on detecting rootkits.

Before you get started with the deployment of QRadar in your infrastructure, you need to understand the several components it makes use of to function properly. IBM QRadar SIEM (Security Information and Event Management) features a modular architecture where you can scale its deployment to add on more devices, endpoints…

Let’s continue our series on Uncovering Attacks by discussing Windows DLLs and a few types of attack vectors relevant to them
