Wetterlage: Ping-Fluten zu Neujahr-.-. --.- -.-. --.- -.-. --.- -.-. --.- -.-. --.- -.-. --.- Vorbereitungen getroffen, um die wieder in Mode gekommenen Ping-Attacken zur Jahreswende einer dezentralen, aber konzertierten Anwendung zu zuführen. post/scrypt: Dem p.t. Publikum der Liste sei ein vom saison/bedingten Wahnsinn möglichst wenig berührter Abend hiemit herbeigewünscht. -.-. --.- -.-. --.- -.-. --.- -.-. --.- -.-. --.- -.-. --.- [...] A new version of a malicious program called the Tribe Flood Network (TFN) is more powerful and harder to detect than an earlier version, according to experts. And an updated sister program called Trinoo is due to be released next week. [...] The program works like this: A TFN attacker secretly embeds software into hundreds of computers. Then, at a selected time, a command is issued that prompts the infected computers to swamp a target Web site or server with messages in a method of attack called "denial of service." The program doesn't damage the "infected" computers or the target, but the sudden flood of messages typically knocks out the target system. [...] This fundamental vulnerability of networked computers makes protecting against denial-of- service attacks extremely difficult. The existence of TFN was reported earlier this week. The new variant, called TFN2K, is potentially more dangerous in that it can enlist machines based on both the Windows NT and Unix operating systems to deliver the flood of messages, according to Gia Threatte of the Packet Storm Web site, which publishes security-related software so system administrators can protect against attacks and intrusions. TFN2K also adds the ability to act on a single command, a stealthier mode of operation than the previous version (which required the controller to send a password), and encrypts communications, making the infecting messages harder to detect, Threatte said. [...] The purported author of the TFN family, who goes by the name "Mixter," sent a version of TFN2K to Packet Storm. Packet Storm said it also expects a new version of Trinoo from Mixter. With the new software being released now and the "2K" allusion to the new year in the name of the program, it appears that a computer attack could occur during the holidays. [...] CERT has warned, "We are receiving reports of intruders compromising machines and installing distributed systems used for launching packet- flooding denial-of-service attacks." CERT said that attackers generally gained unauthorized access to these computers through well-known weaknesses, reinforcing the message that system administrators must stay up-to-date on keeping their systems secure.
