One issue that came from my recent CYBERWARCON talk was an item of focus (or for others, limitation) when approaching the idea of what a “critical infrastructure attack” actually means. While I faced some (really good, topical) questions on my definition of “critical infrastructure”, a more public debate ensued over Read more
The most frustrating type of bad argument to refute are those which feature or rest upon a kernel of truth. In the worst, most-annoying scenario, one must deal with a counterparty that simply reasserts their position without hesitation resembling the chess-playing pigeon of Internet fame. More worrying still is that Read more
I am writing this only a few days removed from Black Hat 2019 and Def Con 27, where both events featured a number of presentations on critical infrastructure or industrial control system (ICS) threats – but with a continuing lack of scope (or imagination) for the threat landscape. While identifying Read more
“When I use a word,” Humpty Dumpty said, in rather a scornful tone, “it means just what I choose it to mean—neither more nor less.” – Through the Looking Glass, Lewis Carroll FireEye recently published a blog covering the tactics, techniques, and procedures (TTPs) for the “TRITON actor” when preparing Read more
In Germany (as well as Austria), there is a type of company referred to as the “Mittelstand”. Generally speaking, these are small- to medium-sized companies, non-public and typically family-owned, providing technical expertise (if not excellence) in a specific niche, usually manufacturing or engineering oriented. Although small, such organizations have outsized Read more
I attended an interesting presentation at the EnergySec Pacific Rim summit discussing the role of machine learning and artificial intelligence (ML/AI) in network security and ICS operations. The talk was mostly an overview of potential applications and niches for ML/AI within these spaces, which in itself is refreshing as ML/AI Read more
As we move into late December (I started writing this on 23 December 2018), all eyes in the information security and especially the industrial control system (ICS) security space typically turn to Ukraine. In 2015 and again in 2016, malicious entities – likely Russian in origin – gained access to Read more
When reporting on cyber-attacks, articles and media frequently (if not exclusively) focus on the damage or immediate result: how many machines were impacted, how much data was compromised, or what (if any) physical consequences emerged from the event. The latter is especially the case with ICS-focused attacks, from Stuxnet to Read more
Recently I engaged in conversation with Dale Peterson dealing with the gas explosion events in Massachusetts. For background, following the event in question there were multiple unfounded claims of a “cyber” cause behind these events followed by significant pushback from various ICS security experts. Where Dale and I enter the Read more
YARA – or “yet another regex alternative” – is a pattern matching tool with multiple uses but extensive application in malware analysis and alerting. The framework itself is simple, relatively easy to understand (especially on basic string matching), and incredibly flexible. Yet in application and advertised use, YARA is often Read more
