Logic Bombs are like a virus right. Except they instead act upon a timed event or a trigger but there isnt any publicity about them. Im asking why they can just be as disturctive as any virus. Im asking why dont you hear about any logic bombs and if you do can you direct me to a place where i can correct my ingornace.
People of the media don't call it like it is...
When was the last time you heard a media person call a computer criminal by his proper name, that of a cracker or script kiddie and not a hacker...
Same applies to a logic bomb...
The reason we never heard about them, is because they are classified as a virus....
logic bomb n.
Code surreptitiously inserted into an application or OS that causes it to perform some destructive or security-compromising activity whenever specified conditions are met.

By the powers invested in www.google.com I here by present these links.

I ran across Bill Gates programming skills back in the mid 80's I recall the logic bomb well here it is..LOL remember Edlin?

A logic bomb can be triggered by what ever design of the programer. The chernobile virus is a good example of a logic bomb on a certian date it triggers off events that destroy the PC it resides on. For example one could code a program to cause and error and then take advantage of a well known function or keyboard command like say remap the keyboard so the next logical action will not cause the desired reaction like ctrl+alt+del will not equal a login but another program to run. Logic bombs are written to take advantage of what a user or program will do in the next logical step but run something else and then program another reaction to the desired effect.
i dont know but i would say viruses are logic bombs..
coz they do damage when certain conditions are met....
To a point s0nIc is sorta correct...
but they also say logic bombs are only damage oriented..
What about a "virus" that spreads itself threw netbios shares and updates the OS with latest patchs every month? wouldnt that be a interesting sight??
; )

no wait.. viruses do something...
The way I see it (and I could be wrong), is Logic bombs and Viruses are the same thing, but they could also be different. For example, if I was pissed off at a single individual, I could write a simple .bat file that would, when executed, format that individuals PC (BOOM). Now because I only sent this to one person and did not write in any code that would cause the program to replicate and send itself to any other PC, this, by definition would not be a virus but could be considered a Logic bomb.
That's just my 2 cents on the subject.
Cheers: :D
Logic Bombs are more like macros. Say a kiddie wants to set up my computer so that if you do not hit the right keys in the right order (let's say crl-alt-1) before they login in as root the system automaticaly begins to shred files then format while a nice little gui screen sits out front saying "now logging in" or something like that. This would keep law enforcment from seeing what they have on their HDD. (good thing most kiddies are not that smart) also the data would actualy have to be shredded not just unmarked or forensic software would still be able to read the information.
Of course you could impliment this in to a virus. Like Palemoon said if you set this same thing to happen whith ctrl-alt-del you'd have a little problem on your hands.
Not that im akiddie but id sure like to see a tutorial on this
Ok now we have decided what a logic bomb is what are some logic bombs names and what exactally do they do (i think i have one) i mean are they that big of a security risk?
Well, it really depends on their payload. You may have more time to find and isolate them that you would with virii because they might be waiting for some procedure to activate, but if they go undetected...
logic bombs check for enviromental changes, like a your name being taken off the payroll, if uve been sacked and then activate teir payload, it is a virus all the same.
And hackers.com whouldnt tolerate a question like that. this is security.

as djm says thier not like normal viruses, they dont replicate, they act more like a trojan, without the remote acces part BUT become destructive when a certain thing happens.

you know, i read abt this from what u guys posted but i read it earlier i just came back, and i got really intrested so i looked it up, i would have to say logic bombs are almost like viruses they both do damage which is obvious and some viruses are triggered and logic bombs do exactly that
well a logic bomb can be just a routine in a virus or a worm for example the big worm that attck NASA was a worm without a doubt yet it had the logic bomb routine hardcoded into it ti was ot reporduce on a certain date and lay dormat in the networks for a couple weeks i believe. so in totality a logic bomb doesnt have to be considered whole but an attribute to a virus or worm
