First JPEG Virus Posted To Usenet
Shawn writes "This could possibly be the worst viruses yet! Earlier this month Microsoft announced a problem in their GDI driver that processes the way JPEG images are displayed. Someone has finally posted an exploit to Usenet. Easynews, a premium Usenet provider, found the virus Sunday afternoon. Up-to-date information about how we found it and what it does is located at virus.txt. When this picture is viewed it installs remote management software (winvnc and radmin) and will connect to irc." from Slashdot

The Morphine Has Hit the Fan
Morphine is a plant (opium poppy)-derived alkaloid and one of the strongest known analgesic compounds. Studies from several laboratories have suggested that animal and human tissue or fluids contain trace amounts of morphine. Its origin in mammals has been believed to be of dietary origin. Here, we address the question of whether morphine is of endogenous origin or derived from exogenous sources. Benzylisoquinoline alkaloids present in human neuroblastoma cells (SH-SY5Y) and human pancreas carcinoma cells (DAN-G) were identified by GC/tandem MS (MS/MS) as norlaudanosoline (DAN-G), reticuline (DAN-G and SH-SY5Y), and morphine (10 nM, SH-SY5Y). The stereochemistry of reticuline was determined to be 1-(S). Growth of the SH-SY5Y cell line in the presence of 18O2 led to the [18O]-labeled morphine that had the molecular weight 4 mass units higher than if grown in 16O2, indicating the presence of two atoms of 18O per molecule of morphine. Growth of DAN-G cells in an 18O2 atmosphere yielded norlaudanosoline and (S)-reticuline, both labeled at only two of the four oxygen atoms. This result clearly demonstrates that all three alkaloids are of biosynthetic origin and suggests that norlaudanosoline and (S)-reticuline are endogenous precursors of morphine. Feeding of [ring-13C6]-tyramine, [1-13C, N-13CH3]-(S)-reticuline and [N-CD3]-thebaine to the neuroblastoma cells led each to the position-specific labeling of morphine, as established by GC/MS/MS. Without doubt, human cells can produce the alkaloid morphine. The studies presented here serve as a platform for the exploration of the function of "endogenous morphine" in the neurosciences and immunosciences.

Cain & Abel
Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, decoding scrambled passwords, revealing password boxes, uncovering cached passwords and analyzing routing protocols. The program comes in two versions because of the differences and limitations of some API.
Version 2.5 is faster and contains a lot of new features like APR (Arp Poison Routing) which enables sniffing on switched LANs by hijacking IP traffic of multiple hosts at the same time. The sniffer can also analyze encrypted protocols such as SSH-1 and HTTPS if used with APR and a Man-in-the-middle situation. Cain also ships routing protocols authentication monitors and routes extractors, crackers for all common hashing algorithms and for other various specific authentications, password calculators (Cisco PIX Hashes, RSA SecurID Tokens), decoders (Access Databases, Base64, Cisco Type-7, Enterprise Manager, Dialup, Remote Desktop) and some utilities like the Cisco Config Downloader/Uploader, the SiD-Scanner, the LSA Secrets Dumper, the Protected Storage Passwords Viewer, the NT Hash-Dumper (works with Syskey enabled), the Abel Remote Console, the MAC Scanner, the Promiscuous-Mode Scanner, the Wireless Scanner and the TCP/UDP/ICMP Traceroute + DNS Resolver + Netmask Discovery + WHOIS resolver (extract informations from RIPE's Database).
However the program is still in beta and may contain bugs.

Nessus & NMAP Cheat Sheet
NMAP and Nessus require no introduction to the security community. Many security auditors have been using this combination for years. NMAP stands out from the other available port scanners for its efficiency and tweaking features.
Nessus takes over where NMAP leave off. NESSUS checks all open ports for various known protocols. Once the service running on the known port is determined, NESSUS then sends data to that service to exploit known security vulnerabilties.
To smartly and innovatively use both tools together, it is often required to remember the command prompt options for both the tools, thats where this cheatsheet comes handy!

Pair of Linux Holes Put Users at Risk
Linux users are at risk from serious security vulnerabilities in components used to view graphics and handle archives, according to researchers. The security holes, found in the imlib graphics library and the LHA archive tool, can be exploited via a specially crafted bitmap image or an LHarc-format archive to take over a Linux system.
Security Awareness Toolbox
'The methods that will most effectively minimize the ability of intruders to compromise information security are comprehensive user training and education. Enacting policies and procedures simply won't suffice. Even with oversight the policies and procedures may not be effective: my access to Motorola, Nokia, ATT, Sun depended upon the willingness of people to bypass policies and procedures that were in place for years before I compromised them successfully.'
Kevin Mitnick
'The Coming Third Wave of Internet Attacks: The first wave of attacks targeted the physical electronics. The second wave - syntactic attacks - targets the network's operating logic. The coming third wave of attacks - semantic attacks - will target data and it's meaning. This includes fake press releases, false rumors, manipulated databases. The most severe semantic attacks will be against automatic systems, such as intelligent agents, remote-control devices, etc., that rigidly accept input and have limited ability to evaluate. Semantic attacks are much harder to defend against because they target meaning rather than software flaws. They play on security flaws in people, not in systems. Always remember: amateurs hack systems, professionals hack people.'

Website offers Caller I.D. falsification service
Caller I.D. spoofing has for years been within the reach of businesses with certain types of digital connections to their local phone company, and more recently has become the plaything of hackers and pranksters exploiting permissive voice over IP systems. But Star38.com appears to be the first stab at turning Caller I.D. spoofing into a commercial venture. Jepson claims the service will charge a twenty-five cent connection fee for each call, and seven to fourteen cents per minute.
