The cybercriminal gang that operated the recently disabled Kelihos botnet has already begun building a new botnet with the help of a Facebook worm, according to security researchers from Seculert. Security experts from Kaspersky Lab, CrowdStrike, Dell SecureWorks and the Honeynet Project, announced that they took control of the 110,000…
Security Researchers Take Down ‘Kelihos Botnet’
Security researchers from four different organizations brought down a botnet by turning a supposed strength of the criminals’ spamming network into a fatal weakness. Experts from CrowdStrike, Dell SecureWorks, the Honeynet Project and Kaspersky Lab crippled the second-coming of the Kelihos botnet on March 21 by “sinkholing” about 118,000 bot-infected…
Researchers find new type of “fileless” malware
Researchers have discovered an extremely rare and possibly unique form of “fileless” malware that executes entirely in memory without the need to save any files to the hard drive of a victim’s PC. The latest discovery was made by Kaspersky Lab, which received reports of a malware attack hitting a…

Rather than presenting users with a conventional static but scrambled series of letters and numbers, NuCaptcha’s video version offers partially rotating text…
RSA security flawed say researchers after collecting duplicate public keys
Cryptography researchers collected millions of X.509 public key certificates that are publicly available over the web and found what they say is a shockingly high frequency of duplicate RSA-moduli keys. “We performed a sanity check of public keys collected on the web,” the researchers state in their paper, published today…

Obstacles no barrier to higher speeds for worms, NYU researchers find
( New York University ) Obstacles in an organism's path can help it to move faster, not slower, researchers from New York University's Courant Institute of Mathematical Sciences have found through a series of experiments and computer simulations. Their findings have implications for a better understanding of basic locomotion strategies…
