South Korean authorities have arrested three teenagers accused of operating a Telegram-based cybercrime network that combined doxxing, harassment, and sexual exploitation into a rapidly growing online ecosystem.
The investigation, carried out in Gyeonggi Province, uncovered a cluster of private Telegram channels known as “bakjebang,” which attracted approximately 10,000 users over several months. The channels were used to distribute personal information and images of women, often without consent, enabling coordinated harassment campaigns.
According to police findings, the operation evolved from small peer-run chat groups into a structured abuse network. Participants actively contributed content, uploading victims’ photos and personal details while fabricating explicit narratives to intensify humiliation and social stigma. Investigators also identified the presence of manipulated media, including deepfake material, alongside illegal content involving minors.
The case highlights how user-driven platforms can blur the line between individual misconduct and organized cybercrime. Authorities noted that the collaborative nature of the channels allowed thousands of users to participate in harassment, effectively turning the network into a decentralized abuse system.
Monetization played a key role in sustaining the operation. One of the suspects reportedly generated revenue by selling advertising space within the Telegram channels, including promotions for illegal gambling services. The group also relied on anonymous SIM cards and other tools to obscure identities and maintain operational anonymity.
Law enforcement traced the activity over a period of several months, from its launch in late 2025 to a coordinated crackdown in December. Undercover investigative work enabled authorities to identify and arrest the suspects following an initial victim complaint. During the arrests, police seized cash and assets believed to be linked to the operation’s profits.
The “bakjebang” network reflects a broader pattern of Telegram being used for illicit communities that scale rapidly through anonymity and low barriers to entry. Previous cases in South Korea have shown similar dynamics, where encrypted messaging platforms facilitate the spread of exploitative content and enable coordinated abuse at scale.
Officials emphasized that even when perpetrators attempt to conceal their activities using VPNs or foreign infrastructure, digital forensics and targeted investigations can still lead to identification and arrest. The case underscores growing concerns around the intersection of social platforms, anonymity tools, and organized online abuse networks.
