Malware plays a key role in most of today's cyber attacks and has consolidated as a commodity in the underground economy. In this work, we analyze the evolution of malware from 1975 to date from a software engineering perspective. We analyze the source code of 456 samples from 428 unique families and obtain measures of their size, code quality, and estimates of the development costs (effort, time, and number of people). Our results suggest an exponential increment of near","authors_text":"Alejandro Calleja, Juan Caballero, Juan Tapiador","cross_cats":["cs.SE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-11-16T16:09:40Z","title":"The MalSource Dataset: Quantifying Complexity and Code Reuse in Malware Development"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.06888","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":"sha256:77fa8ce5e1f0a6d3ea572de1921cd5805c5ad16f3249a9ce7179e475a8870a52","target":"record","created_at":"2026-05-18T00:00:33Z","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":"a63d0774d3844039bd0bc32c65bdb4f8c92402b06f8d0a7ff3cf16cdd26b90c5","cross_cats_sorted":["cs.SE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-11-16T16:09:40Z","title_canon_sha256":"33dee0bdca02a7096c6f3307493de3d740bc0a75862afb5b10f448339f3af103"},"schema_version":"1.0","source":{"id":"1811.06888","kind":"arxiv","version":1}},"canonical_sha256":"c2753f9e44b6753629c6f9bcf428e59e94c59ba67c8897429c185e1cbb789e37","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c2753f9e44b6753629c6f9bcf428e59e94c59ba67c8897429c185e1cbb789e37","first_computed_at":"2026-05-18T00:00:33.565818Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:00:33.565818Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"FfMoGk74VMI8PPXW3bqy/a1SiSl6m/Sc97wFoukLCqj+TgcdBvwkXUCiIm70PwOD5eoPiEqnZ6UPK7GwuEEiAw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:00:33.566384Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.06888","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:77fa8ce5e1f0a6d3ea572de1921cd5805c5ad16f3249a9ce7179e475a8870a52","sha256:a719fd0d39bbfaf131a7891df52ea0cb0557d877d71f9b2fc648423430a1a2b4"],"state_sha256":"cbf04d53ca109899609b7f67d0906325d85af5cf0ef2849cf9bf5194343e4021"}
