Web Security Snapshot Has Some Surprises

Posted on May 22, 2012 by jnelson

Symantec, a major Net security company, has published a report on Internet security threats of 2011. It’s an interesting snapshot of trends and statistics that makes sobering reading, along with a few eyebrow-raising surprises. Here are some of its highlights: A dangerous new trend among criminals is using shortened URLs to distribute and disguise spam and phishing attacks. These links are conveniently provided by numerous websites to handily replace lengthy strings in addresses, but where they actually point to may be hard to guess. Users are advised to use preview tools to check them out before clicking. Social media sites, especially Facebook, have been cleverly used to spread links to infected sites by crooks taking advantage of people’s expectations and profiles. People using social networking sites are cautioned to be careful about what personal information they post, and when clicking on URLs in email or posted on social media sites even when they come from friends or trusted sources. Macs are not immune: the first Mac-based botnet occurred in 2009. New threats emerged in 2011, including Mac Defender, a fake antivirus program that installs itself without permission. Symantec claims to have identified 4,989 new computer vulnerabilities in just 2011. However, the number of new problems with popular browsers has decreased slightly, Google Chrome having the most dramatic reduction.

Late in the afternoon of Sunday, May 20, there will be an annular eclipse of the Sun – and Albuquerque is dead-center along the path of maximum coverage. And the view should be truly awesome as the Sun sets as a burning ring of fire. Solar eclipses are, of course, caused by the Moon passing in front of the Sun. But the Moon’s distance varies, and so those eclipses where the entire Moon is between us and the Sun vary also. Since the Moon was at its closest to Earth recently with the “supermoon” when it was last Full (and therefore opposite the Sun), now on the other side of its orbit it will be at its farthest point from us when it passes in front of the Sun, and will appear smaller. While during a total solar eclipse, the Moon exactly covers the entire solar disk, in an annular eclipse like this, a thin brightly-glowing strip around the edges will still be visible. This means that when the Moon passes before the Sun that afternoon, it will not cover it completely but leave a red burning circle in the sky. Though the sky should not blacken and the stars come out as the flaming atmosphere of our parent star suddenly becomes visible, the view from right here should be pretty … Continue reading →
