DDoS-for-hire service provider jailed Matthew Gatrel, a 33-year-old man from St. Charles, Illinois, has been sentenced to two years in prison for running websites that provide powerful distributed denial-of-service (DDoS) attacks against internet users and websites. This sentencing resulted in the seizure of his websites, making the internet a little safer from DDoS attacks. Gatrel was the administrator and owner of DownThem.org and AmpNode.com, two DDoS-for-hire websites with thousands of clients which launched attacks against more than 200,000 targets. He was convicted of three…

Surprise, not surprise, I posted the research!  Informally, I'd like to break down a little more what it could be useful for. App Timeline Provider logs mouse, keyboard, and audio activity for apps that are in focus on Windows 8+ machines. If you have mouse and keyboard activity within an app, you're validating that the window was "in focus" and that it was interacted with. If you have audio input and audio output, you can…

App Timeline Provider – SRUM Database

The System Resource Usage Monitor (SRUM) is a currently parsed artifact available on Windows 8+ systems. On a basic level, SRUM appears to be the backend database supporting the Task Manager. These tables are stored in an Extensible Storage Engine (ESE) database saved as SRUDB.dat. Generally, there are 30 to 60 days of data saved in this database. The data is written to the database approximately every hour and around shutdowns. Some the tables within…

The Effect of Ransomware After The Investigation

Ransomware. It’s a word that has become interwoven into the fabric of global corporate, business and legal vernacular. The threat is briefed to executive leadership teams during security update calls and to boards of directors during quarterly earnings calls. Its risks are part of mergers and acquisitions (M&A) strategy planning and are specifically identified in cyber insurance coverage policies with exclusions and sub-limits. And an entire industry exists around threat intelligence, in which the proverbial…

A Conversation about Transitioning to Incident Response

In working on AboutDFIR the last couple months, I’ve come to learn that while digital forensics and incident response share some basic foundational knowledge, they are widely different in practice. I’ve taken SANS FOR500: Windows Forensic Analysis and have been reading the recent articles about vulnerabilities, and have to say it’s been a series of eye-openers, especially coming from a law enforcement digital forensic background, as to how evidence and analysis can differ depending on…

My Experience: FOR508 & GCFA

First Time GIAC: Studying for the GCFE

Reading about SANS courses and GIAC certifications prior to this experience was a little overwhelming. Depending on dozens of factors, people that post online seem to have either a good or terrible experience.
