A handful of existing works focus on dirty-label attacks with wrongly-labeled poisoned training samples, which may fail if a benign model trainer corrects the labels. In this paper, we propose Megatron, an evasive clean-label backdoor attack against vision transformers, where the attacker injects the backdoor without manipulating the data-labeling process. To generate an effective trigger, we customize two loss terms based on the attention mec","authors_text":"Bowei Tian, Meng Xue, Qian Wang, Shuike Li, Xueluan Gong, Yanjiao Chen","cross_cats":["cs.CR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2024-12-06T04:39:41Z","title":"Megatron: Evasive Clean-Label Backdoor Attacks against Vision Transformer"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2412.04776","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:3e319226731ac41ab2e61144bdb090fe55c0f19e25093f5dbba7c807576c1962","target":"record","created_at":"2026-07-05T09:45:23Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"833f38a8fd9e57e38284d0d6c67d6dae389207f872ad10085cc035368c1f3ec5","cross_cats_sorted":["cs.CR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2024-12-06T04:39:41Z","title_canon_sha256":"41843bd02d1e8cd5857d9fe66e313792c398dbda5e8a7c08136ffaaa0d6f218e"},"schema_version":"1.0","source":{"id":"2412.04776","kind":"arxiv","version":1}},"canonical_sha256":"e7e818525ee111ca3f70aca34dae561ceddaf732398de74c83d6a6c682dd8255","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e7e818525ee111ca3f70aca34dae561ceddaf732398de74c83d6a6c682dd8255","first_computed_at":"2026-07-05T09:45:23.661516Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:45:23.661516Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"vApy1eKQBJL5ioCLennoiFND0LGoc/v0cXNw9qmDawpRVulIJGjZh8Di2HQjtvkpgP1LcmRvlUi4+nq/brZgCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T09:45:23.662005Z","signed_message":"canonical_sha256_bytes"},"source_id":"2412.04776","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3e319226731ac41ab2e61144bdb090fe55c0f19e25093f5dbba7c807576c1962","sha256:62d256b1bae6c4b203813f8cfcbd881ede9c4545670a9047c4b91986a2539aeb"],"state_sha256":"c105bebcce5977ad33cd663166f995214d3542c9f06ac6ef9b86df673e044198"}
