The stakes are high due to the cost of the certification ($789 per attempt as of this writing…

Jailbreaking – Checkra1n Configuration

In this installment, I felt that I should discuss how to use Checkra1n, and how to actually get into the device via 2 methods: localhost (tethered) and WiFi (untethered). This is not a blog to discuss how Checkra1n is doing, what it is doing, or what Checkm8 is doing prior to the device booting. Additionally, you do this at your own risk. Just because it works on one device does not mean it'll work on…

Pattern of Life – Tracking Through Mobile Applications

So getting back into blogging finally! Thanks for hanging in there with me.  Unlike my last posts, time to roll up the sleeves and try to make this community better from a technical perspective.

Forensic Tools

Forensic tools, whether software or hardware, or just like traditional forensic science tools - they are designed by humans and typically meant to be used by trained users who understand both the artifacts they are processing as well as the results produced by the tool. Some tools are as simple as a USB write blocker - you plug one end into a computer, you plug a USB device into the other end, and it "just…

Threat Hunting for Non-Threat Hunters

Posted by MIKE ART REBULTAN at https://www.peerlyst.com/posts/threat-hunting-for-non-hunters-mike-art-rebultan-mit-ceh-ecsa. Threat hunting is a proactive task with an assumption that your organization has already been breached and you wanted to beat the average “dwell time” of 256 days; at least for me as a DFIR practitioner. And this is usually done with the help of different tools that we call “arsenals”; SIEM (security information and event management) and EDR (endpoint detection and response) mostly. However, security is not…
