NZ researchers Will Frame and Jacob Torrey seeded decoy session-cookie Canarytokens into infostealer operators' logs; they report about a three-day lull after compromise before validity checks and a spike in login attempts once logs are sold
iTnews reported on 30 October 2026 that New Zealand researchers Will Frame, who runs the free Restealer infostealer monitoring service, and Jacob Torrey, head of labs at Thinkst Applied Research, deliberately infected their own machines with malware to plant a new type of Canarytoken built from session cookies in infostealer operators' databases.

The researchers told iTnews: "There's an [approximately] three day window post-compromise where nothing happens, then a few initial checks to see if the credentials are valid, then you can tell once they've been sold as the login attempts shoot up."
Frame said the early checks were almost certainly log providers checking the logs before releasing them to subscribers. (source: iTnews)
According to iTnews, Frame said infostealer log subscriptions range from as little as US$300 for lifetime access from newcomers to US$5,000–US$10,000 from larger providers, with session cookies, which can let an attacker into an account that has already passed a multifactor authentication check, included in whole logs at no extra cost. iTnews says the pair will present the full results at the Kawaiicon security conference in Wellington on Friday 30 October.

- Browser session cookies stolen by infostealer malware (MFA bypass via session replay)

- Patch to
- Treat an infostealer infection as a full credential and session compromise: revoke active sessions and tokens as well as resetting passwords, since stolen session cookies can bypass MFA. Monitor for leaked credentials and suspicious session reuse, and shorten session lifetimes or bind sessions to devices where your identity provider supports it.
