Cyber Threat Actor: TurkHackTeam

TurkHackTeam, also known as TurkGuvenligi, is a Turkish hacking collective that has been active since at least 2014. The group operates under aliases such as TurkHackTeam and TurkGuvenligi and is based in Turkey. Its activities consist primarily of website defacements carried out to convey political messages. The collective has claimed responsibility for actions taken in response to specific geopolitical events and has used social media handles to publicize its operations.

The group’s targeting has focused on governmental, financial and international organizations located in Europe and the Middle East. In 2023 it defaced the websites of Danish banks and government agencies, stating that the attacks were motivated by a Quran‑burning incident in Denmark. Earlier, in July 2014, it defaced two United Nations sub‑domains (esango.un.org and escwa.un.org) as part of the #OpSaveGaza campaign, and later that year it altered the OpenSSL website after exploiting weak passwords at the hosting provider. The collective’s typical method involves gaining access to a target’s web hosting environment, often by exploiting weak or default credentials, and then replacing site content with protest statements; no malware families or sophisticated tooling have been reported in the open sources.

Among its most visible operations, the 2023 Danish bank and agency defacement stands out as a recent example of politically motivated disruption, while the 2014 UN sub‑domain defacements illustrate its participation in broader hacktivist movements. The group also gained notoriety for compromising the website of the Syrian Electronic Army in January 2014, an act described as retaliation after breaching the SEA’s hosting provider. Additionally, TurkGuvenligi claimed responsibility for defacing the OpenSSL site, a maneuver attributed to insecure passwords at the hosting provider. Publicly available information does not link the collective to any state sponsor or criminal consortium; it is described solely as an independent Turkish hacking group.
