This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.
Indication of Infection
When printing a document and the seconds field is greater than 55 it will insert the text:
' And finally I would like to say: STOP ALL FRENCH NUCLEAR TESTING IN THE PACIFIC! '
at the end of the document.
When starting Word or opening a document on April 5th it will override the file C:\IO.SYS on Windows platforms and an error message occurs.
The virus tries to drop the file infecting virus Ph33R to the users system on startup if the hour is 5 pm but is unsuccessful because of a mistake in the code. This generates a 'WordBasic Err=125' MessageBox
Methods of Infection
General Information about Macros
Macros can be used in applications such as Word or Excel to automate complex or repetitive tasks. Once written, macros are assigned a keystroke combination, toolbar button or menu item which will activate the macro.
Macros are saved as a series of instructions in a language such as VisualBasic. Once recorded, the user can edit the macro or even add sophisticated instructions that are not normally recordable. This gives the knowledgeable user the capability to not only automate functions within the application, but to perform system functions such as deleting, renaming, or setting file attributes.
General Information about Macro Viruses
A Macro Virus uses the application's built-in power and functionality to replicate and spread. When a user receives and opens a file containing a viral macro, the viral macro will be either automatically run by opening the document or will be executed by the user by a certain key combination, a menu command, a toolbar button, etc. The viral macro will copy itself, the method depending on which application the viral macro is written for. The Macro Virus will now be present in files that the user opens, and can spread through various distribution methods. Some dangerous things a Macro Virus can do besides simply spreading could be to delete/change document contents, change settings in the Word environment, set a password, delete files, copy a DOS Virus to the user's system or insert harmful lines into the config.sys or autoexec.bat files.
Theoretically, a Macro Virus can be written for any application that stores a macro in a form that can be opened and edited using a language such as WordBasic or VisualBasic. In practice, most Macro Viruses discovered are predominantly written for Word and Excel.
Cross Platform Capability
Macro Viruses can potentially spread across different platforms such as PC to Mac, etc. Macro Viruses exist and spread within the application environment, which for macros is common among the different platform versions. Some Macro Viruses that try to do damage to a part of the user's system outside of Word will not be able to do that damage on a different machine platform. For example, a Macro Virus that tries to edit the user's Config.sys file on a PC is going to have a hard time doing the same thing on a Mac, which has no Config.sys file. So a Macro Virus that spreads and does damage on one machine could spread to another type of machine and replicate but do no damage. It is possible for a Macro Virus to figure out what kind of system its running on, and change its behavior accordingly, but this is not common.
