GhostSec claims to have disconnected 4,097 CANTV modems via TR-069 during the June 28 elections in Venezuela

Coinciding with Election Day on July 28, 2024, in Venezuela, the hacktivist group GhostSec claimed to have exploited misconfigured modems belonging to the state-owned company CANTV, manipulating passwords, network settings, and the TR-069 remote management protocol to prevent CANTV from reconfiguring them remotely. According to the claim reported by the media, 4,097 modems were taken offline, including the Stavix MP-X421R (1,930), Huawei DG8245V-10 (1,654), ZTE F670L (414), and ZTE ZXH108N v2.5 (99) were disconnected. The group stated that its target was the state-owned company and the government, not the general public, since most users still had 4G mobile access. The figures and scope come from the group’s own statement and were not officially confirmed by CANTV.
