Exploiting Virtual Machines with RAM Row-Hammer Attacks
A “Row-hammer” attack exploits a physical problem that exists in RAM where an attacker can actually cause bit-flips in DRAM memory. This has already been exploited and attacks successfully gained kernel privileges. Researchers have taken this a step further and, by exploiting a Host kernel feature known as “memory de-duplication”, can flip bits in a controller […]
The Cyber Kill-Chain: Revisited
The Nay Sayers Trolling through articles released this week, I came across a review of Lockheed Martin’s “Cyber Kill Chain” that was written by CSO Online: https://www.csoonline.com/article/2134037/cyber-attacks-espionage/strategic-planning-erm-the-practicality-of-the-cyber-kill-chain-approach-to-security.html on 11/7/2017. I found the article to be somewhat disingenuous. The CSO Online article was more of a rehash of a Dark Reading article: https://www.darkreading.com/attacks-breaches/deconstructing-the-cyber-kill-chain/a/d-id/1317542? written on 11/18/2014. “We’re not afraid to […]

As indicated in the post, this is based on the standard Exchange Online Protection (EOP) services offered by Microsoft, not Advanced Threat Protection (ATP). I currently run two manage much smaller Email systems for two ESPs. I’ve always worried about anti-spam measures, trying to be effective, without too […]
Oh Brother (printers): Denial-Of-Service
Brother printers that are connected to a network are vulnerable to a Denial-Of-Service (DOS) attack through the printer’s embedded web server (called “Debut”). Of course, the attacker must have the ability to access the printer’s Web Server. No Brother printer should be exposed to the Internet. You should also put Brother printers on their own […]

Social(Networking+Engineering) Defeats Physical Security
I found an interesting article on Motherboard from a Pentester named Sophie Daniel. She did more than your standard online cybersecurity Penetration Testers do; she gained unrestricted physical access to a secure facility. Here’s the general process of the attack: Acquired Business Information Solicited business Information through website data, aerial/satellite photographs, and maps. Acquired Personnel […]
