> CIAC has obtained a Trojaned copy of the AOL4FREE.COM program that, if
run,
> deletes all the files on a user's hard drive. If you are e-mailed this

> or if you have downloaded it from an online service, do not attempt to
run

> If the program was received as an attachment to an e-mail message, do not
> double click (open) it. Opening an attached program runs that program,

> in this case deletes all the files on your hard drive. The original

> Detection
> =========
>
> AOL4FREE.COM is a Trojan program that is 993 bytes (2 sectors) long.
> It masquerades as the AOL4FREE program that allows the fraudulent
creation
> of
> free AOL accounts. The following text is readable in the AOL4FREE.COM
file
> if you display it with the DOS TYPE command or the DOS EDIT program.
>
> Compiled by BAT2EXEC 1.5
> PC Magazine . Douglas Boling
>
> Note that this text may appear in any program compiled with the BAT2EXEC
> program and has nothing to do with the Trojan Horse.
>
> If you open the AOL4FREE.COM file with a disk editor or with the Windows
> Notepad program, the following text is found at the end of the second
> sector
> of the file.

> Recovery
> ========
>
> Pressing Ctrl-C before the Trojan Horse finishes deleting all your files
> will
> save some of them. If the program runs to completion, all the files on
> your root drive will have been deleted. The files are deleted with the
> DOS DELTREE command, so the contents of the files are still on your hard
> disk, only the directory entries have been deleted. Any program that can
> recover deleted files will allow you to recover some or all of the files
> on your hard disk.
>
> While attempting to recover files, be sure to not write any new files
onto
> the hard disk as the new files may overwrite the contents of a deleted
> file,
> making it impossible to recover. You will probably have to boot your
system
> with a floppy and run any recovery programs from there.
>
> If you happen to have one of the delete tracking programs installed on
your
> system (a program that keeps track of deleted files in case you want them
> back) the recovery operation will be relatively simple. Follow the
> directions
> in your delete tracking program to recover your files. If not, you will
> probably have to recover each file individually, supplying the first
> character
> of the file name, which is overwritten in the directory when the file is
> deleted. Most DOS/Windows disk tools programs also have the capability
for
> recovering deleted files so follow the directions included with those
> programs
> to do so.
>
> Background
> ==========
>
> The original AOL4FREE.COM program was developed to fraudulently create
free
> AOL accounts. The creator of that program has pleaded guilty to
defrauding
> America Online for distributing that program. Anyone else attempting to
use
> that program to defraud AOL could also be prosecuted.
>
> An e-mail message was recently circulating about the Internet that warned
> of
> an AOL4FREE virus, but that warning is either a hoax or a badly
> misunderstood
> description of this Trojan Horse.
> 1. This program is a Trojan Horse, not a virus. It does not spread on
its
> own.
> 2. A Trojan Horse must be run to do any damage.
> 3. Reading an e-mail message with the Trojan Horse program as an
> attachment
> will not run the Trojan Horse and will not do any damage. Note that
> opening an attached program from within an e-mail reader runs that
> attached program, which may make it appear that reading the
attachment
> caused the damage. Users should keep in mind that any file with a
COM
> or
> .EXE extension is a program, not a document and that double clicking
or
> opening that program will run it.
>
> CIAC still affirms that reading an e-mail message, even one with an
> attached
> program, can not do damage to a system. The attachment must be both
> downloaded
> onto the system and run to do any damage.
