Greetings! In the forgotten Academy of Woods by yoro, a research and analysis was performed on the events from 25th of February this year. A description of the "Balkan magic" is given and graphical representation of the associated accounts is shown.
A bug that can be classified in Common Vulnerabilities and Exposures (CVE) has happened with the introduction of the deploy button. Typical for major security vulnerabilities a codename is given. This CVE is called "Balkan magic" due to the localized adoption and the great impact it has in battle performance.
With more investigation turned out that any booster was able to push back the deploy progress bar without additional costs. The original theory I came up with is not the answer.
Exploit. The energy consumed in deployment is not affected by a following activation of any booster. It is set at the start. This causes a discrepancy between the energy utilized for dealing higher hit count and the actual energy consumed based on starting setting. In example, 100 energy for 10 hits becomes 100 energy for 50 hits. The boosters become unintended decimator for consumed energy.
The bug is invoked when an Accelerator booster is activated during an ongoing deployment. The booster increases the rate at which the hits are made. This reasonably leads to more hits done in the same time interval. Therefore more hits can be done in the duration of the deployment. In example, 10 hits deployment will become 50 hits deployment with activation of x5 accelerator. No problematic behavior until now. The energy consumed in deployment is calculated based on the amount of energy set by user at the start and the progress bar completion at the moment of end.
Exploit. The energy consumed in deployment is not affected by a following activation of an accelerator booster. This causes a discrepancy between the energy utilized for dealing accelerated hit count and the actual energy consumed based on non-accelerated hit count. In example, 100 energy for 10 hits becomes 100 energy for 50 hits with activation of x5 accelerator. The accelerator booster becomes unintended decimator for consumed energy.
Reason. The cause of this behavior may be explained with classic fight button. The classic fight button had limit of 1 click per second. In order to make the accelerator booster functional in reasonable manner, instead of making the click time limit lower, one click with accelerator resulted in multiple hits instead. On average over many clicks the effect is the same as clicking x-times faster. This multiplier of hits was introduced in deployment with similar intent. But it was not fully accounted for accelerator activation during ongoing deployment. Then the accelerator will just multiply the hits corresponding to 100% deployment completion. For example user X has 7/10 hits done, 70% progress. When user X activates x5 accelerator the deployment will have 7/50 hits done or 14% progress. But user X will use energy for 10 hits, giving actual full deployment progress of 50/10, or 500% for same costs.
Now I present the graphs illustrating the effects of the ongoing investigation on accounts associated with the "Balkan magic".
With highly active and developed accounts banned, the affected countries will suffer sudden power balance reversion. Inability to maintain present state of wars is already being accepted. The legitimacy of the bans are still in question, because in some cases the high activity can lead to unintended and occasional trigger of the exploit. Also somewhat inactive accounts are also put in the large count. The pack use will experience a drop since active account are also most likely pack users. Finally, admins have stated that the list may not be complete. The investigation is ongoing.
Finally, thanks to Master_rg for making the ban tables.
