According to Russian security firm Doctor Web, there are an increasing number of Mac-focused Trojans that install extensions for Safari, Chrome, and Firefox. These extensions are designed to embed third-party ad code into otherwise unrelated Web pages, funneling the clickthrough revenue back to the malware authors. The Trojans use a variety of techniques to fool users into installation, including masquerading as video plug-ins, media players, download accelerators, and more. To be safe, avoid installing software from sites that prompt you to do so — always get software from trusted sources. follow link
Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.
Beware Trojans Bearing Ads
Does this mean one should turn off AutoUpdate or use it strictly as a notice that one should go the original vendor's web site to get the latest update?
The main thing is, if a Web page pops up a dialog saying "You need the IMGOINGTOSTEALYOURFACE plugin to view this content." click Cancel and close the page as quickly as possible. And even if a site says, "You need the Microsoft Silverlight plugin to view this content." go to the Microsoft site manually to download and install it, rather than getting it from the prompt.
Does this mean extensions from other sources are suspect? How does one go about determining their safety? (Crap, and I thought Mac users didn't have to fuss about this stuff.)
This is actually a big deal, and I believe Google has changed Chrome so that you can download Chrome extensions only from the Chrome Web Store rather than from developer sites for just the same reason.
