Internet users can be blind-sided by e-mail "cluster bombs" that inundate their inboxes with hundreds or thousands of messages in a short period of time, thereby paralyzing the users online activities, according to a new report by researchers at Indiana University Bloomington and RSA Laboratories in Bedford, Mass.
IUB computer scientist Filippo Menczer and RSA Laboratories Principal Research Scientist Markus Jakobsson describe in the December 2003 issue of ;login: a weakness in Web sites that makes the e-mail cluster bombs possible. A miscreant could, the authors say, pose as the victim and fill out Web site forms, such as those used to subscribe to a mailing list, using the victims own e-mail address.
One or two automated messages would hardly overload an e-mail inbox. But Menczer, associate professor of informatics and computer science, said special software called agents, web-crawlers and scripts can be used by the bomber to fill in thousands of forms almost simultaneously, resulting in a "cluster bomb" of unwanted automatic reply e-mail messages to the victim. The attack can also target a victims cell phone with a sudden, large volume of SMS (short message service) messages.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
