      Worm strikes down Windows 2000 systems
      CNN, New York Times, ABC report crashes

      Tuesday, August 16, 2005; Posted: 6:28 p.m. EDT (22:28 GMT)




      Computer Worm
      WASHINGTON (CNN) -- A computer worm shut down computer systems running the Windows 2000 operating system across the United States on Tuesday, hitting computers at CNN, ABC and The New York Times.

      Around 5 p.m. computers began crashing at CNN facilities in New York and Atlanta. ABC said its problems began in New York about 1:30 p.m.

      The Caterpillar Co. in Peoria, Illinois also was reportedly affected.

      David Perry of Trend Micro said that the attack seems to have been triggered by a new worm, called worm--rbot.ebq. He said the symptoms -- computers repeatedly shutting down and rebooting -- was consistent with that virus.

      Johannes Ullrich, director of the Sans Institute, a network security firm in Jacksonville, Florida, said the outage also may have been caused by the Zotob worm, which was released last weekend.

      "It will connect to a control server to ask for instructions. It scans network neighborhoods and tries to infect them, as well," Ullrich said.

      Several versions of the worm have been released, some as late as Tuesday, he said.

      While the worm primarily affects Windows 2000, it also can affect some early versions of Microsoft XP, he said.

      Typically, the virus enters a system via a laptop connected to unsecured networks, Ullrich said. "This laptop will infect your systems from the inside."

      Microsoft has made a patch to counter Zotob, he said.

      At any given time, there are thousands of computer worms and viruses in existence. Most are stopped from becoming widespread problems by anti-virus software

      New worms prevention and cure

      August 17, 2005

      Takeaway:
      New worms picks up where Zotob left off. Check out this prevention and cure report.

      By Robert Vamosi

      Just as the initial threat of the Zotob worm fades, new and much more malicious worms have hit the Internet with force. Early signs are that there are as many as eleven different worms each using a variety of patched vulnerabilities, including DCOM-RPC, LSASS, WebDAV, and the recent MS05-039 Windows Plug and Play vulnerability. The new worms include an IRC backdoor for communication, as well as the ability to add or delete network shared folders, steal private information, and launch a denial-of-service attack on random targets. Because these new worms allow remote access and may damage system files or launch a denial-of-service attack, these worms (collectively) rate a 7 on the CNET/ZDNet Virus Meter. Check this alert during the day for updates.

      How it works
      The new worms use port scanning and network shares to spread. The worms look for Windows 2000 systems that have not been updated recently, then connect to IRC servers to download malicious code.

      Many of the new worms use a file called WINTBP.exe and make the following changes to the system registry:

      HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Run "wintbp.exe" = wintbp.exe

      Some of the worms attempt to remove traces of other worms from an infected system.

      Some of the new worms use a variety of denial-of-service attacks, including PING flood, SkySyn flood, SYN flood, TCP flood, and UDP flood.

      In some cases, the presence of these worms on a Windows 2000 system may cause that system to reboot repeatedly.

      Prevention
      Initial reports suggest that only Windows 2000 may be affected. It is important that you update your Windows system immediately with the latest patches. Also, a desktop firewall should help block much of this attack.

      Removal
      Antivirus software companies have updated their signature files to include these new worms. Updates will stop the infection upon contact and in some cases will remove an active infection from your system. For more information, see Computer Associates, F-Secure, McAfee, Norman, Panda, Sophos, Symantec, and Trend Micro.

      :cheers: Greetings Sis Jahness!! I tried to find better info- truth be told I was kinda scared to start my 'puter up because I have windows 2000 AND SBC-my interenet provider- was hit by this virus as well...but it seems as if all is well-for now. Asante for your post, I updated, scanned and it seems to be alright.


      Peace and blessings your way Sis, once again you are on time and on point

      Arrow Bots Break Into 175 Companies In Year's Biggest Attack

      Bots Break Into 175 Companies In Year's Biggest Attack


      By Gregg Keizer, TechWeb News
      2:11 PM EDT Wed. Aug. 17, 2005

      The ongoing attack of multiple bot worm families stepped up Wednesday, said security experts, who noted that so far more than 175 corporations have been hit with malicious code exploiting Windows 2000's Plug and Play vulnerability.

      A new wave of bots, including two that are particularly malicious, have struck scores of corporations, including the Associated Press, the Canadian Imperial Bank of Commerce, Caterpillar, Inc., CNN, Daimler/Chrysler, General Electric, SBC Communications, and United Parcel Service.

      "The bots are not affecting the Internet at large," said Oliver Friedrichs, the senior manager of Symantec’s security response team. "But they are affecting a number of world's biggest business. So far we know of 175 corporations that have been hit by the attacks."

      Although by some counts there have been more than a dozen bots released that exploit the Windows 2000 Plug and Play vulnerability disclosed last week, Symantec sees two of them as especially potent: Zotob.e and Esbot.a.

      --------------------------------------------------------------------

      (Like so many malicious code outbreaks, nomenclature can be deceptive. Zotob.e, for instance, is also known as Rbot.cbq, while Esbot.a is tagged as various versions of Rbot, Sbot, or even IRCbot. Confusion reigns.)

      Both these bots not only use the Plug and Play vulnerability to gain access to a Windows 2000 PC, but they also include code that opens an IRC channel back to designated servers, from which they can download additional code to further compromise the machine, or turn it into a denial-of-service (DoS) or spam zombie.

      The rate of infection by Zotob and its brethren has certainly increased, said Gunter Ollmann, the director of Internet Security Systems' (ISS) X-force research group. But it's hard to tell by how much, since the botnet operators have taken to putting their host in invisible mode so that eavesdropping researchers can't get an idea of how many PCs have been compromised.

      Microsoft continued to downplay the outbreak, with a spokesperson on Wednesday again referring to it as a low level threat, a stance the Redmond, Wash.-based developer has maintained since the outbreak began Sunday. "Zotob has thus far had a low rate of infection. Zotob only targets Windows 2000," said the spokesperson.

      Some security experts disagreed.


      "This is one of the most significant threats we've seen in 2005," said Friedrichs. "These two are only the fourth and fifth level '3' threats this year." In 2004, Friedrichs noted in comparison, Symantec dubbed 33 threats as level 3 or higher.

      The outages at corporations worldwide was likely caused by Zotob.e or Esbot.a, or another of the Zotob variants, said Friedrichs. "What we're seeing is an evolution since Sunday of the attacks, where propagation techniques have been improved.

      "Once one of these bots gets inside the perimeter, it spreads rather quickly in the soft interior. We've seen as many as 2,000 hosts infected in just one hour."


      Friedrichs said it was possible that many of the compromised corporations were hit when an infected laptop was re-connected to the company network. But he wouldn't rule out a straight-forward attack on the firewall in some of the cases.

      "Anti-virus software is certainly effective once a threat has been identified, but an intrusion prevention system would have prevented this out the door, since they look for attacks against the vulnerability, not for a specific exploit."

      Other analyst say the blame isn't on a lack of defensive systems, but a lax attitude toward patching. As Microsoft has noted repeatedly in its nearly-constantly-updated security advisory, patched systems are invulnerable to the bot attacks.

      "I see Microsoft's situation, as damned if it does, damned if it doesn't," wrote JupiterResearch analyst Joe Wilcox on his blog. "If the company doesn't disclose vulnerabilities, customers are put at risk. If it discloses, customers are put at risk. My recommendation is if you're damned either way, than be damned if you do. Better Microsoft releases patches than not. But that means customers must patch as soon as possible."
