rmogull writes "Brian Krebs over at the Washington Post just published a story that Heartland Payment Systems disclosed what may be the largest data breach in history. Today. During the inauguration. Heartland processes over 100 million transactions a month, mostly from small to medium-sized businesses, and doesn't know how many cards were compromised. The breach was discovered after tracing fraud in the system back to Heartland, and involved malicious software snooping their internal network. I've written some additional analysis on this and similar breaches. It's interesting that the biggest breaches now involve attacks installing malicious software to sniff data — including TJX, Hannaford, Cardsystems, and now Heartland Payment Systems." One bit of good news out of this massive breach is that, according to Heartland's CFO, "The nature of the [breach] is such that card-not-present transactions are actually quite difficult for the bad guys to do because one piece of information we know they did not get was an address." Heartland just put up a press release on the breach.

Adam Korbitz writes "New Scientist is reporting the extrasolar planet MOA-2007-BLG-192Lb — whose discovery was announced just last summer — may actually be the first truly Earth-sized exoplanet to be identified. A new analysis suggests the planet weighs less than half the original estimate of 3.3 Earth masses; the new estimate pegs the planet's size at 1.4 Earth masses. The planet orbits a small red dwarf star, some 3,000 light-years from here, at an orbital distance of 0.62 astronomical units, about the same distance as Venus from our sun. One significance of the planet's discovery is that it points to the probable ubiquity of smaller terrestrial planets in somewhat Earth-like orbits around red dwarf stars, the oldest and most numerous stars in the galaxy. Here is a video report from the discoverers."

The Science Daily site has up a piece on the effect user-generated content can have on map-making. Scientists are appreciative of the data enthusiastic mappers can provide, updating maps on changes in local geographic information. "Goodchild's paper looks at volunteered geographic information as a special case of the more general Web phenomenon of user-generated content. It covers what motivates large numbers of individuals (often with little formal qualifications) to take part, what technology allows them to do so, how accurate the results are and what volunteered geographic information can add to more conventional sources of such information."
