[] []
[] :: SIX WAYS TO KILL OR SAVE A NETWORKS BBS!!!!!!:: []
[] []
[][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][]
[] []
[] 1) Unauthorized Sysop Access: []
[] -THIS CAUSED BY A USER TYPING IN A PASSWORD THAT []
[] INVOLVES THE NUMBER ONE. (I.E. M1PQ, E1LH, P1TT, []
[] D1SK, ETC.). THESE USERS DO NOT HAVE TO KNOW YOUR []
[] PHONE NUMBER TO RECIEVE ACCESS. AFTER THEY RECIEVE []
[] THE PROMPT: 'INVALID PASSWORD', THEY HAVE GAINED []
[] THE ACCESS THAT HAS BEEN GIVEN TO YOUR PASSWORD. []
[] FROM HERE THEY SIMPLY TYPE IN ANY NAME THEY PREFER, []
[] AND FROM THERE THEY ENTER NONE FOR THE TELEPHONE []
[] NUMBER AND BANG, FREE SYSOP ACCESS. []
[] -IT IS CAUSED BECAUSE THE NETWORKS PROGRAM READS []
[] THE FILES AND LOADS THE FILES WHEN M1PQ, OR ANY []
[] OTHER PASSWORD IS ENTERED. NETWORKS DOESN'T CLEAR []
[] OUT THE VARIABLE JUST AS IT DOES WITH A NEW USER. []
[] -THERE ARE TWO WAYS TO ELIMINATE THIS: 1) MAKE THE []
[] USERS ENTER A VALID PHONE NUMBER, OR CLEAR THE []
[] VARIABLE OUT BEFORE ENTRY ONTO THE BOARD. 2) []
[] LOWER THE SYSOP ACCESS AND ONLY VALIDATE HIS []
[] ACCESS BEFORE HE IS GOING TO LOG ON THE BOARD. []
[] 3) JUST CLEAR THE VARIABLE OUT AFTER THE USER []
[] ENCOUNTERS THE MAXIMUM AMOUNT OF ERRORS BEFORE []
[] BEING LOGGED OFF. []
[] -THE WAY THAT I FEEL WOULD BEST SUIT OUR PURPOSE []
[] IS FORCING THE USER TO ENTER A PHONE NUMBER, []
[] THUS CAUSING HIM TO GO THROUGH THE NEW USER PROCESS []
[] AND CLEAR OUT THE VARIABLE. []
[] -I AM SURE THAT MOST OF YOU ARE SAYING TO YOUR- []
[] SELVES, "BIG DEAL" BECAUSE THE USER IS NOT []
[] VALIDATED. IT MAY BE A BIG DEAL ON SOME SYSTEMS []
[] BECAUSE THE USER(HACKER) MAY BE ABLE TO READ SOME []
[] MESSAGES THAT ARE MEANT FOR VALIDATED USERS ONLY, []
[] OR THEY MAY BE ABLE TO GET AN IDEA OF WHO IS ON []
[] THE SYSOP BLACKLIST, JUST FROM THE TITLES. []
[] []

[] []
[] 2)Crashing with the Library []
[] -ANOTHER WAY NETWORKS CAN BE CRASHED IS BY GOING []
[] TO THE LIBRARY OR THE 'G' SECTION AND TYPING ANY []
[] NUMBER THAT HAS A DECIMAL POINT IN IT. THAT DOES []
[] NOT EXCEED THE MAXIUM NUMBER OF THE MENU. (I.E. []
[] 1.2, 3.2, 4.1, 5.6, ETC.). THIS PROCEDURE WILL NOT []
[] DO ANY DAMAGE, UNLESS THEY TYPE: '1.SYS' AND WITH []
[] THIS AT HAND THEY CAN CAUSE THE COMPUTER TO TRY TO []
[] OPEN A FILE WHICH IS NOT THE PROPER ONE. FROM []
[] THERE IT MAY CAUSE THE COMPUTER TO GO INTO MONITOR []
[] AND WHICH AT THIS POINT, YOU ARE SCREWED. GETTING []
[] BACK ON TRACK, THE FILES WHICH INCLUDE DECIMALS []
[] IN THEM ARE WRITING ONE SECTOR TEXT FILES TO DISK. []
[] CONSIDERING THAT MOST BOARDS RUN ON TWO DRIVES THIS []
[] MAY FILL UP A DISK REAL FAST. []
[] -TO ELIMINATE THIS PROBLEM YOU WILL HAVE TO LOOK []
[] AROUND 10440 TO CORRECT THE PROBLEM. []
[] []
[][][][ ORACLE OF DELOS...................(312)/528-7017!][][][]
[] []
[] 3)Crashing with E-Mail []
[] -THE 99E99 TRICK, (WHICH WILL WORK WITH 99E98, []
[] 99E97, ETC). WILL CAUSE THE COMPUTER TO GO INTO []
[] MONITOR IF IT IS DONE ENOUGH. THIS ONLY WORKS IN []
[] E-MAIL SO LOOK FOR THE PROBLEM THERE. WHAT THE []
[] USER HAS TO DO FROM THE MAIN MENU IS THIS: []
[] SEND MAIL? Y []
[] []
[] SEND TO (FIRST NAME): GARBAGE []
[] (LAST NAME): CAN []
[] []
[] IS THIS CORRECT? Y []
[] []
[] GARBAGE CANS LOCKER CONTAINS (0) []
[] LETTERS, SEND LETTER? Y []
[] []
[] ->30 LINES MAX WITH WARNING ON LINE 4<- []
[] ->TO ENTER EDITOR TYPE (/EX)<- []
[] []
[] 1> ENTER GARBAGE HERE []
[] 2> /EX []
[] []
[] -> S)END, F)IX, L)IST, A)PPEND. []
[] WHICH? S []
[] []
[] MESSAGE SAVED. SEND MORE MAIL? 99E99 []
[] []
[] SEND TO (FIRST NAME):KEEP []
[] (LAST NAME):DOING THIS []
[] []
[] -BY THE USER DOING THIS ABOUT TEN TIMES IT WOULD []
[] EVENTUALLY GO INTO MONITOR. []
[] -THIS CAN BE AVOIDED BY ADDING AN ONERR STATEMENT, []
[] BUT WATCH WHERE IT POINTS BECAUSE IF IT POINTS []
[] IN THE WRONG PLACE, IT MAY SCREW UP THE STACK []
[] THUS CAUSING THE USER TO GO INTO MONITOR. []
[] []
[][][][ ORACLE OF DELOS...................(312)/528-7017!][][][]
[] []
[] 4)Crashing with Memory []
[] -FILLING YOUR FREE MEMORY IS ANOTHER POPULAR []
[] TECHNIQUE THAT COULD CAUSE YOUR BOARD SOME []
[] PROBLEMS. WHAT THE USER HAS TO DO IS GO INTO []
[] F>EEDBACK WITH THE 8O COLUMN SELECT MODE ON, []
[] AND LEAVING FEW OR NO BLANK LINES, FILL UP []
[] F>EEDBACK UNTIL THE MEMORY IS FULL AND IT THROWS []
[] HIM INTO MONITOR. AGAIN, THIS IS AVOIDED BY THE []
[] ONERR STATEMENT. IT CAN ALSO BE AVOIDED BY LIMIT- []
[] ING THE LENGTH OF YOUR NETWORKS PROGRAM. IN GENERAL []
[] THOSE WITH //e'S OR //+'S WITH 16K CARDS HAVE LITTLE []
[] WORRY. []
[] []
[][][][ ORACLE OF DELOS...................(312)/528-7017!][][][]
[] []
[] 5)New User Crashing []
[] -ANOTHER WAY A USER CAN GO INTO MONITOR IS BY, []
[] LOGING IN AS A NEW USER, AND FOLLOWING ALL THE []
[] WAY THROUGH UNTIL PHONE NUMBER. AT THIS TIME TYPE []
[] AN 'O' AND DO THIS ABOUT 8 TIMES. IT WILL KEEP []
[] ASKING FOR A NAME SO JUST KEEP FEEDING IT GARBAGE. []
[] -TO AVOID THIS YOU COULD MAKE 'O' AN INVALID COMMAND []
[] AND FORCE THE USER TO TYPE THE FULL WORD 'OFF'. []
[] []
[][][][ ORACLE OF DELOS...................(312)/528-7017!][][][]
[] []
[] 6)Deleting System Files []
[] -A USER CAN DELETE FILES BY INSERTING SPACES BEFORE []
[] A TITLE. THUS BY TYPING NW.USERS .SYS, THIS FILE []
[] FILE CAN DELETED JUST AS ANY OTHER. []
[] -THIS CAN BE AVOIDED BY NOT ALLOWING SPACES BEFORE []
[] A TITLE. (OBVIOUSLY) []
[] []
[][][][ ORACLE OF DELOS...................(312)/528-7017!][][][]
[] []
[] NOTE: ONCE THE USER HAS PUT HIMSELF IN MONITOR, HE []
[] SIMPLY NEEDS TO TYPE A: ^C. []
[] []
[][][][ ORACLE OF DELOS...................(312)/528-7017!][][][]
[] []
[] 1)Tricks for fun []
[] -BY TYPING THE WORD 'OFF' NETWORKS WILL LOG A USER []
[] OFF ALMOST ANYWHERE IN THE PROGRAM. WHETHER THE []
[] LOGOFF COMMAND HAS BEEN CHANGED OR NOT. []
[] -BY TYPING ^S ^N THE SERIAL NUMBER WILL BE DISPLAYED []
[] ON MOST NETWORK SYSTEMS. []
[] []
[][][][ ORACLE OF DELOS...................(312)/528-7017!][][][]
[] []
[] MORE WILL BE ADDED TO THIS LIST AS TIME PASSES ALONG! []
