Conficker Virus outbreak - 32 by milosz - Spiceworks Community

Back in 2009, it was estimated that about 9 to 15 million computers around the world were infected with Conficker, a computer worm that can infect a machine and automatically spread itself to other computers on the network, with no interaction from the user. The first version of the Conficker worm was detected in the wild back in 2008. The worm has been making the rounds online since then; Microsoft reported in mid-2011 that some 1.7 million machines were infected with the worm. To address the Conficker worm threat, Enigma Software Group released the free Conficker Removal Tool. It is a software application that will scan your Windows operating system, detect the Conficker worm, and remove it. If your system is not infected with the worm, the Conficker Removal Tool will tell you that it did not find the Conficker worm on your system. To start using the Conficker Removal Tool you need only to download it off the web and onto your computer; you do not need to install it. The download will complete in a blink as it is a lightweight 491KB. All you have to do next is run the executable you downloaded. You will be presented with the Conficker Removal Tool’s interface and you will have to press Start. A wizard will then guide you through the removal process of the Conficker worm. Do not forget that a reboot is required for every step of the process. If the Conficker Removal Tool does not detect the Conficker worm on your system, it will present a “Conficker Not Found” prompt. You can go ahead and exit the application. Please note that when you exit, your default browser will launch and you will be directed to a survey page on the Enigma Software Group website. You will be asked to recount your experience with the free Conficker Removal Tool – if you want to of course. It must be mentioned here that Microsoft released a patch for the Conficker worm and that antivirus solutions detect the worm as well. So if you have a patched and up-to-date system

Macworld.com – If you’ve been paying attention to general computer news, you may have read about the Conficker worm, and what may (or may not) happen to Windows PCs that are infected with Conficker on April 1. The worm has received a lot of attention, leading more than a few Mac users to ask about the worm’s impact on OS X. Mac security maker Intego received so many inquiries that the company added a Conficker entry to its blog. So, as a Mac user, how worried should you be about Conficker? The short answer to the question is that, unless you’re running Windows inside a virtual machine or via Boot Camp, you really don’t have much to fear from Conficker. It’s a worm that takes advantage of Windows systems with unapplied security patches–a population that may be as high as 30 percent of the Windows machines out there. Conficker won’t work on OS X at all, so most Mac users have nothing to fear from the worm. If you do use Boot Camp and/or Windows inside a virtual machine, however, you should make sure your system has the latest Microsoft patches, and may want to use a third-party anti-virus utility to check to see if your installation has been infected by Conficker. Microsoft also offers a free Conficker removal tool. What exactly does Conficker do? At the moment, nobody really seems to know. Symantec’s security researchers, for instance, theorize that the network of Conficker-infected machines will be “rented out to criminals who want to send spam, steal IDs and direct users to online scams and phishing sites.” The reality is that, because Conficker isn’t active at the moment, nobody knows how it may be used. What is known, however, is that on April 1, certain variants of Conficker will take some active steps to further protect themselves from detection and removal. Infected machines are effectively under control of those who wrote Conficker, and they can install malicious code at their discretion. If you’re using Windows–either on your Mac or directly on an Windows PC–I strongly recommend you take the necessary steps to make sure you haven’t been infected. If you’re only using OS X, you’ve got nothing to worry about, at least relative to the Conficker worm.

Conficker's ties to a large spamming and password-stealing botnet give credence to the speculation that money, and possibly malicious Eastern European hackers, are behind the latest Internet worm infection. Elinor Mills covers Internet security and privacy. She joined CNET News in 2005 after working as a foreign correspondent for Reuters in Portugal and writing for The Industry Standard, the IDG News Service and the Associated Press. The Conficker worm that has infected millions of Windows-based computers will likely be used to send spam and steal data much like one of the nastiest botnets on the Internet does, researchers said on Thursday after finding links between the two worms.A week after failing to do anything but snore, the much hyped Conficker worm was roused from its slumber on Wednesday, with infected computers transmitting updates via peer-to-peer and dropping a mystery payload onto PCs. Researchers suspect that the payload program may be a keystroke logger, a spam generator, or both. Conficker now also tries to connect to MySpace.com, MSN.com, eBay.com, CNN.com, and AOL.com as a way to test that the computer has Internet connectivity, deletes all traces of itself in the host machine, and is set to shut down some functionality on May 3. In addition, Conficker reaches out to a domain that is known to be infected by a worm called Waledac and downloads an encrypted file. Researchers are analyzing that code and the program that is dropped directly onto infected machines by other infected machines to find out exactly what is in it. And they suspect that Conficker and Waledac are coming from the same people. "I'm pretty certain the same people are behind both of them," said Paul Ferguson, an advanced threats researcher for Trend Micro. "Conficker has got their (Waledac creators') fingerprints all over it." Computers infected with Waledac comprise what Ferguson called the "most pernicious spamming botnet on the Internet." Waledac spreads via a malicious Web link or an e-mail, typically a fake Christmas greeting or Valentine's Day message, or with a subject line related to the inauguration of President Obama. It generates spam and steals data,. Conficker free download - Conficker Removal Tool, Sophos Conficker Cleanup Tool, Win32/Conficker Worm Removal Tool, and many more programs.

Like passwords, from infected computers. Ferguson said he believes Eastern Europeans are behind the Waledac worm. He suspects they created the Storm botnet to try different payloads and business models and that Waledac resulted from that. Ferguson speculates that they may be putting their lessons learned from earlier efforts into practice with Conficker. "There is empirical evidence that these guys are a for-hire, for-profit criminal operation on the Internet and that Conficker is nothing more than part of that organization's best efforts to monetize their efforts on the Internet," Ferguson said. Vincent Weafer, vice president of Symantec Security Response, confirmed the Waledac connection with Conficker, but wouldn't speculate on who exactly might be spreading the worms. The fact that Conficker now downloads a Waledac file "reconfirms our belief that ultimately this is a large botnet designed to make money," he said. "It's the first example of how these guys are trying to leverage this botnet for profit."As for the May 3 expiration date in the latest Conficker code, Weafer said it appears to be trying to shut down code related to the first variant of Conficker, Conficker.A, which generated more noise on the Internet than later versions did.Symantec researchers are calling the latest Conficker code that is circulating a new variant of the worm and have dubbed it Downadup.E, with Downadup being another name for Conficker. The worm spreads via a hole in Windows that Microsoft patched in October, as well as through removable storage devices and network shares with weak passwords. The worm disables security software and blocks access to security Web sites. To check if your computer is infected you can use this Conficker Eye Chart or this site at the University of Bonn. There is also a Conficker removal guide on CNET's Download.com site. People are being urged to be careful in their quest for Conficker removal tools. Marshale8e6 has found spam that takes advantage of the hype over the Conficker worm to scare people into installing fake antivirus software.

Weighing in on Conficker on

Conficker, also known as Downup, Downadup and Kido, is a computer worm that surfaced in October 2008 and targets the Microsoft Windows operating system. The worm exploits a previously patched vulnerability in the Windows Server service used by Windows 2000, Windows XP, Windows Vista, Windows Server 2003, Windows Server 2008, Windows 7 Beta, and Windows Server 2008 R2 Beta. The worm has been unusually difficult for network operators and law enforcement to counter because of its combined use of advanced malware techniques.The worm exploitsMS08-67 unpatched servers.- The Conficker worm related vulnerability identification CVE : CVE-2008-4250 Missed Patch MS08-067OVAL ID : oval:org.mitre.oval:def:6093 CVSS v2: AV:N/AC:L/Au:N/C:C/I:C/A:C/E:ND/RL:ND/RC:ND/CDP:ND/TD:ND/CR:ND/IR:ND/AR:ND CWE: CWE-94 (Failure to Control Generation of Code (aka ’Code Injection’) Known exploit : Metasploit Malware report : ThreatExpert reportHere are some tools and utilities used to identify and tocontain the Conficker worm. Meanwhile, US-CERT raises a National Cyber Alert (TA09-088A) Downatool2The domain names of different Conficker variants can be used to detect infected machines in a network. Inspired by the "downatool" from MHL and B. Enright, we have developed Downatool2. It can be used to generate domains for Downadup/Conficker.A, .B, and .C. Memory DisinfectorIt is hard to identify files containing Conficker because the executable are packed and encrypted. When Conficker runs in memory it is fully unpacked. The memory disinfector scans the memory of every running process in the system and terminates Conficker threads without touching the process it runs in. This helps to keep the system services running Detecting Conficker Files and Registry Online

Computers on the same network. How does the worm infect a computer?: The Downadup worm tries to take advantage of a problem with Windows (a vulnerability) called MS08-067 to quietly install itself. Users who automatically receive updates from Microsoft are already protected from this. The worm also tries to spread by copying itself into shared folders on networks and by infecting USB devices such as memory sticks. Infection process: Conficker is delivered as a Dynamic Link Library (DLL), so it cannot run as a standalone program and must be loaded by another application. A vulnerable Windows system is generally infected with the Conficker worm via the MS08067vulnerability, using exploit shellcode that injects the DLL into the running Windowsserver service. Other possible infection vectors are accessing network shares or USB drives where the malicious DLL is started via the rundll32.exe application. Once infected, Conficker installs itself as a Windows service to survive reboots. It then computes domain names using a timeseeded random domainname generator and attempts to resolve these addresses. Each resolved address is contacted and a HTTP download is attempted. No successful HTTP download was witnessed until the middle of March 2009, at which point security experts observed nodes that downloaded encrypted binaries from some of the randomly generated domains.Thinking about ways to attack Conficker's infrastructure, this DNS based update feature is obviously a potential target. However, Conficker uses RSA signatures to validate the downloads and rejects them if the check fails, and attacking RSA is not feasible.Conficker version control: Conficker is definitely a sophisticated piece of malware with built-in version control! Each Conficker version installs a couple of named mutexes during startup,to make sure that older version of the code are not run. This is achieved by registering all previous mutex names plus an additional mutex with a different name in each version. If mutex creation fails, this indicatesthat another Conficker version is already running which is at least as recent as the one currently being executed. However, there seems to be a flaw in conficker's mutex generation mechanism mechanism. It is assumed that theConficker authors made a mistake that effectively renders the concept of using mutual exclusion useless. Possibly fixed in the next release? It is quite common in modern malware to patch a vulnerability after successful exploitation, to prevent other malware from also infecting the compromised system. Conficker is no exception here. Conficker.B contains a routine to update itself by scanning incoming exploitation attempts from otherinfected machines and downloading the new malware binaries from the attacker.Conficker generates a series of domain names from which it tries to download updates. Conficker.A and .B create 250 domains per day. This puts high load on the contacted domains and can.
