Earlier this afternoon, for example, I got call from “American Express” suggesting that I needed to “verify a transaction.” The caller used a robotic voice similar to the one used by American Express’ automated systems, and only obvious signals that it was a scamContinue reading “Attack Technique: AI Clones”

When a device first joins a network, the upstream network hardware has full control over its traffic and can allow/block any packets sent from the device from reaching the Internet. Many public networks (typically Wi-Fi, but sometimes wired), located in hotels, coffee shops, mass transit, schools, etc. require that the user accept Terms of UseContinue reading “Attack Techniques: Fake Captive Portals”
Cybersecurity Metaphors
Uneven Protection Attacks flow like water: if you have a hole in your defenses, attacks will flow through that hole. Unless they’re trying to win a prize or show off, attackers do not bother attacking where your security posture is strongest. Making your tallest wall taller usually isn’t useful. Encryption Security folks love encryption, forContinue reading “Cybersecurity Metaphors”
Exploiting Vulnerable Drivers
Often, attackers will attempt to prevent security software from interfering with their attack chains by abusing a vulnerable driver to kill or otherwise disable the system’s security software (antivirus/edr/etc). Because drivers run in highly-privileged OS Kernel mode, it is difficult to prevent attackers from achieving their goals if they manage to achieve code execution inContinue reading “Exploiting Vulnerable Drivers”

After you sign up on the Social Security Administration’s website, they’ll send you a yearly email inviting you to check out your benefits. Flipping through my Junk Mail folder this afternoon, I found the following email: It looks reasonably plausible, except for the return address (cuonlineedu.in, a university in India). I’m always game to lookContinue reading “Attack Techniques: RMM Abuse”
