There are allegations that LG Uplus attempted to destroy evidence by disposing of servers related to the APPM server, which manages insider accounts, after suspicions of a cyber intrusion were reported. LG Uplus has refuted these claims, stating that the disposal was part of a pre-planned process unrelated to the controversy.
According to industry sources on October 22, LG Uplus physically disposed of one account management server on July 31. This occurred about ten days after a white-hat hacker reported server hacking incidents at both KT and LG Uplus on July 18, prompting the Korea Internet & Security Agency (KISA) to notify both companies and request internal inspections.
On August 12, criticism was raised during the National Assembly audit that LG Uplus had attempted to erase related traces by updating the server OS connected to APPM. Some in the security industry have pointed out that, due to the server disposal, it is impossible to determine what information hackers may have stolen, emphasizing the need for an internal investigation.
An LG Uplus representative stated, "The server that was decommissioned on July 31 was an account management solution from another company, not the product at the center of the recent controversy. The data format, including data names, was different from those disclosed in the Freck report, so the disposal is unrelated to the current suspicions. The server was decommissioned as planned on July 31, following a migration process after a new system was rebuilt in February last year."
