Watering hole attack prevention

Watering hole attack prevention

A watering hole attack is an indirect attack on a victim. Rather than directly attacking the victim’s network, the attacker attacks a web site that the victim’s employees are likely to visit. Then the attacker attacks the victim’s network, via its own workstations, from that web site. A former colleague asked me how you protect against watering hole attacks, and I thought this was a good exercise. So here are some strategies for watering hole attack prevention.

Phone call saying services are stopped on your computer? It’s a scam.

“Hello? My name is Max and I’m calling from CSA. We got a report saying that services are stopped on your computer.”

I hung up, for lack of energy to fight with “Max,” or even to try to convince him my name is Suchita. But if that phone call sounds familiar, feel free to hang up on Max, or whatever he says his name is. It’s a scam. If you want to know why, read on.

Gigabit card only connecting at 100mbps? Here’s the fix.

Gigabit card only connecting at 100mbps? Here’s the fix.

I finished a modernization project where I replaced all of my 100-megabit gear with gigabit-capable gear, including my cabling and router and access points. But after I replaced my last 100-megabit switch, I found we had two Windows 7 desktops refusing to speed up. Here’s how to fix a gigabit card only connecting at 100mbps.

First, if you know you’re not connecting at gigabit, you probably already know how to do this. But if not, here’s how to check your network speed in Windows 10.

Taming Windows 95/98/98SE/ME Out of Memory Errors

The symptom: If you install more than 512 MB of RAM in a system running Windows 9x (that’s any version of Windows 95, 98, 98SE, or ME), you get weird out of memory errors.

The culprit is a bug in Windows 9x’s disk cache. The solution is to limit the cache to use 512MB of memory, or less, which is a good thing to do anyway. Here’s how.

How safe is my computer from hackers?

On Monday, March 13 at approximately 10:30 AM CST, I will be appearing on KFUO Radio’s Faith and Family program to discuss home computer security with host Andy Bates. One of the questions he’s planning to ask: How can I know how secure my home computer is? Or, to put his question another way, how safe is my computer from hackers?

I’m going to use this space to elaborate ahead of time on some of the things we are going to talk about. We could talk for an hour on any of the questions he’s going to ask, and he gave me three questions and 25 minutes. This is my workaround.

Migrate Windows 7 to SSD or install fresh?

Here’s a good question. Should you migrate Windows 7 to SSD or install fresh? And what about Windows 10? This is likely to be controversial and everyone has an opinion. I’ll weigh the pros and cons of each, as a guy who knows  a little about optimizing Windows, and who has been using SSDs since 2009.

The HP Elitebook 8440p and Windows 10

I got an HP Elitebook 8440p because I wanted something a little newer and faster than my old Dell E1505. It was certainly newer and faster, but it had a problem. Every morning it greeted me with a BSOD. That E1505 was getting older and it had its own quirks, but I don’t remember it ever bluescreening on me. Here’s how I fixed the bluescreens I got with the HP Elitebook 8440p and Windows 10.

Not only did it bluescreen, but the behavior seemed pretty consistent. Two days in a row, I woke the laptop up from hibernation, and about nine minutes later, it bluescreened.
