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.

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 troll him by telling 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. Better yet, block calls from people like him entirely. It’s a scam. If you want to know why, read on.

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

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. Here’s how to get around those memory limitations to make Windows 95 and Windows 98 work with 2 GB of RAM.

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.

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.

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.

Optimize Windows 10 for better performance

Optimize Windows 10 for better performance

When I first installed it, I thought it was pretty pointless to try to optimize Windows 10. Of course, I installed it from scratch on a computer with an SSD and 16 gigs of RAM. Then I upgraded a couple of computers from Windows 7 to Windows 10, and I started to see why some people might not like Windows 10 all that much.

Upgraded systems almost always run slow, but I’d forgotten how much slower. And while you didn’t have to do much to Windows 7 to make it fast–that’s one reason people liked it–I find some Windows 10 optimization seems to be necessary. But don’t visit dodgy sites like downloadmoreram.com. Follow these tips for things that actually work.
