[Massively] MapleStory economy collapses due to hackers - Page 2

post #11 of 55
Quote:
"packet-forging exploits have been used for some time to alter the damage players deal to monsters or receive from them. Combined with meso guard, hackers were able to fool the game into hitting them for -2,147,483,648 damage (the largest negative value a signed 32-bit integer can hold). Since the damage was a negative value, the meso guard skill then granted the player over two billion mesos. Hacking players used their ill-gotten gains to buy up practically everything in players' market stalls, massively inflating the game's economy by pouring untold billions into the hands of random players."

It happened in kms too? Know last night this exploit as found in the north american servers, not the european servers.

Also, this is the second time it happened in north american servers, first time was giving negative amounts to an npc, sucks that last night's server check didn't seem to fix the recent problem though. Guess I'm not going to do anything but afk for the next few days or so, for the free cash they tend to hand out lol.

My friend was the first person in North America to hit level 200, he's pretty much set for life as he would also inflate the market and then sell his "Meso's" online, he showed me his bank account one day a few years ago and he made $500,000 just from selling his gold.

Ridiculous.

Even with this game as is, it's still better than Runescape.

Though this is quite funny

That's all that's needed to keep this kind of exploit from occurring.......

Also, no server rollback??? Really? This sounds like a poorly coded and even worse managed pos of a game.
maybe it should be:

Code:
if (hacker = true) {
 currPlayer.subMembership(BAN BAN BAN BAN BAN);
 format C:/;
 disp('Eat a bagel, you turd');
}

Here's some pseudocode of how it could work (incredibly simplified of course). In layman's terms: Log the player's activity, if we detect enough suspicious activity in a period of time, ban-hammer.
Code:
const int LEVEL_REQUIRED_FOR_BAN = 5;

// Whenever something suspicious is found we send it to the logging util
void LoggingUtil::LogSuspiciousActivity( Object& player, ActivityType type, std::string& details )
{
     // Create a new piece of info to hold our details
     PlayerSaveInfo info;
     info.type = type;   // Type is something like "Suspicious Activity"
     info.details = details;

     // Send the info to the player class (on the server), so save it to the DB
     player.AddSaveInfo( info );
}

// Code on player class
void Player::AddSaveInfo( PlayerSaveInfo& info )
{
     // Save this data to the player's permanent record
     StoreInfo ( info );

     // If the info was suspicious activity
     if ( info.type == SUSPICIOUS_ACTIVITY )
     {
           // Increase the suspected activity level on this player
           ++susActLevel;

           // If the player now exceeded the amount of activity needed for a ban
           if ( susActLevel > LEVEL_REQUIRED_FOR_BAN )
           {
                  // Lay down the banhammer
           }
     }
}

I used to play...this game years ago, like 4-5 years ago.

I use the term play loosely because I was away most of the time and I had several 100s before the game turned to crap.
