EigenLayer restaking-frontend phishing cohort — Ethereum — 2024–2025

Loss
no aggregate figure is sourced. The one quantified case is the October 2024 hijack of EigenLayer's X account, in which at least $800K was lost by a single victim per Scam Sniffer (Decrypt, 2024-10-18). The earlier "mid-seven-figures" aggregate and the victim-loss range were unsupported and have been removed.
OAK Techniques observed
OAK-T3.005 (Fake-Validator Staking-Frontend Phishing — primary; the EigenLayer restaking interface is a staking-frontend phishing surface structurally similar to the Lido stETH staking-interface campaigns); OAK-T4.002 (Spoofed Token Approval — Blockaid documented Angel Drainer abusing queueWithdrawal-style approvals against EigenLayer users in February 2024); OAK-T4.009 (Pre-Token Brand-Anticipation Phishing — structurally adjacent; the October 2024 X-account hijack promoted a fake EigenLayer airdrop).
Attribution
unattributed — multiple pseudonymous phishing operators. The earlier claim of DPRK infrastructure overlap has no supporting source and was removed.
Corrected 2026-10-11
Removed the unsourced "mid-seven-figures" aggregate, named typosquat domains, DPRK-overlap attribution and fabricated campaign waves; anchored the file on the sourced October 2024 EigenLayer X-account hijack (≥$800K from one victim) and Blockaid's February 2024 Angel Drainer queueWithdrawal finding; fixed the EigenLayer launch framing.
Key teaching point
Any protocol with a large "stake now" flow amplified by a points or pre-token incentive program is a phishing surface. The primitive is the same across protocols: the user intends to deposit into a known contract, and a spoofed frontend, hijacked official account, or malicious approval request routes assets to an attacker. Official-account compromise (the October 2024 hijack) lets attackers skip the typosquat step and borrow the protocol's own trust.

Summary

EigenLayer ran a restaking points programme before its token, which created a large population of users hurrying to deposit LSTs and ETH, and a token airdrop narrative that phishers could exploit. Two sourced events anchor this cohort.

In February 2024 Blockaid reported that the Angel Drainer kit had adapted to target restaking platforms, using a queueWithdrawal approval-farming flow against EigenLayer users (crypto.news, 2024-02-01). In October 2024, around EigenLayer's token launch, the project's X account was hijacked to promote a fake airdrop; Scam Sniffer reported at least $800K lost by one victim (Decrypt, 2024-10-18).

The LRT protocols built on EigenLayer (Renzo, Ether.fi, Puffer, Kelp) share the same deposit-flow shape and therefore the same class of exposure, but this file does not claim specific campaigns against them: no sources were found for named typosquat domains, search-ad campaigns, or Symbiotic/Karak-targeted waves, and those earlier claims were removed.

Realised extraction

At least $800K from one victim in the October 2024 incident. No source-backed aggregate for the cohort; victim self-reporting is incomplete.
