SingularityNET bridge attack widens with 260M AGIX and 53.8M WMTx as cluster hits $16.77M

The ASI Alliance security tape widened Sunday after PeckShield flagged the same attack cluster that drained Fetch.ai’s converter minting 260 million AGIX and 53.838 million WMTx on Ethereum. At 09:21 UTC on September 20, PeckShield valued that cluster’s Ethereum holdings near $16.77 million—about 198.3 million AGIX (~$14.42 million), 649 ETH (~$1.67 million), and 33.538 million WMTx (~$627,350). That print sits on top of the earlier FET drain and NuNet NTX mint already logged on 8bitcrypto’s Rug Room desk and is the new story: unauthorized SingularityNET-bridge inventory, not a rehash of the September 19 converter cash event alone.
Fetch.ai’s 16:19 UTC update said Fetch.ai contracts were not under threat and that FET continues to operate normally. The team framed the breach as hitting SingularityNET contracts—“primarily the SingularityNET Bridge between Ethereum and Cardano”—with unauthorized mints using that route. AGIX-to-FET conversions are paused, and Fetch.ai’s Ethereum-side bridge was paused as a precaution even though the team said it found no indication of a vulnerability in that contract. Attribute those containment claims to Fetch.ai’s own posts; do not invent a SingularityNET root-cause brief that has not been published.
World Mobile Chain confirmed at 05:07 UTC that the SingularityNET bridge had been exploited and that WMTx had been minted on Ethereum without authorization. The team said it was contacting exchanges to freeze affected deposits and working with security partners to revoke minting authorities. A 06:31 UTC follow-up said a pre-exploit snapshot was underway and told holders not to interact with WMTx while the investigation continued. Both posts warned against recovery DMs, fake support accounts, and unofficial migration links—standard Rug Room hygiene when mint keys and bridge authorizers fail in the same incident window.
For timeline context without rewriting the prior FET/NTX wire: the first cash event remains the 20:21:47 UTC September 19 drain of about 8.72 million FET (~$1.53 million per PeckShield) from TokenConversionManagerV3, followed at 20:50:11 UTC by a 408.53 million NTX mint (~$462,730) to the same recipient cluster. Fetch.ai’s preliminary ASI:One write-up described a compromised SingularityNET bridge authorizer key used to produce a valid converter signature alongside a separately compromised NuNet mint key. The AGIX and WMTx Ethereum mints that PeckShield priced into the $16.77 million holdings figure followed from that cluster on September 20.
Bitquery separately reported at 17:20 UTC that roughly 2.3 billion newly created units across AGIX, NTX, CGV, and WMTx were traced to the same actor, plus the FET drained from the converter. That multi-ticker, multi-chain count should be read alongside—not instead of—PeckShield’s Ethereum AGIX/WMTx snapshot. Until contract states are reconciled across Ethereum, Cardano, and BNB Chain, treat headline dollars as minted inventory plus FET drained, not as fully realized cash-out proceeds.
Exchange desks moved in parallel. Bitget suspended FET deposits and withdrawals from 06:00 UTC+8 on September 20, citing wallet maintenance, with spot trading left open and no resumption time specified. KuCoin was separately reported to have halted FET deposits over the same window. FET traded near $0.18 at the September 19 drain and around $0.172 on September 20 (~5% down). Newly minted supply drove NTX sharply lower—trackers cited drops from about 65% to more than 90%—while early WMTx coverage put the token down roughly 43% after the unauthorized mint hit venues.
What remains missing is a standalone SingularityNET incident post matching Fetch.ai and World Mobile’s cadence, a full AGIX/WMTx/CGV mint transaction list, and a reconciled circulating-supply table. Desks covering ASI Alliance rails should watch for official mint-authority revocations, exchange freezes on unauthorized AGIX and WMTx deposits, and any corrected supply figures before treating PeckShield’s $16.77 million cluster valuation as final loss. Attribute PeckShield’s AGIX/WMTx counts, Fetch.ai’s bridge framing, World Mobile’s WMTx warnings, and Bitquery’s multi-token estimate to those September 20 sources. Ignore unsolicited recovery messages; rely only on official Fetch.ai, World Mobile, and SingularityNET channels.
