WaSteal Update: Infrastructure Pivoting Reveals 57 Additional Extensions, Campaign Now at 183 Total
The WaSteal campaign involves a large number of malicious Chrome extensions used for data exfiltration. Recent analysis revealed 57 additional extensions linked to the same operator and backend, bringing the total to 183 active extensions on the Chrome Web Store. These extensions share the same exfiltration behavior and remain live, posing ongoing risk to users who install them. The campaign is actively tracked and reported by threat intelligence sources, but no specific patch or remediation guidance is provided in the available data.
AI Analysis
Technical Summary
WaSteal is a malicious campaign involving Chrome browser extensions that exfiltrate user data. An update from threat researchers using infrastructure pivoting techniques uncovered 57 more extensions tied to the same operator, increasing the total number of malicious extensions to 183. All identified extensions remain live on the Chrome Web Store, indicating ongoing exposure. The campaign uses a consistent backend and exfiltration method across all extensions. The information is sourced from a Reddit cybersecurity post linking to detailed external reports but lacks specific technical exploit details or patch information.
Potential Impact
Users who install any of the 183 malicious Chrome extensions risk data exfiltration to the attacker's backend. The extensions are actively live on the Chrome Web Store, enabling continued victimization. There is no indication of exploitation in the wild beyond the campaign's presence, and no vendor advisory or patch information is available. The impact is primarily on user privacy and data security due to unauthorized data exfiltration.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should avoid installing suspicious or unverified Chrome extensions, and organizations should monitor for these extensions in their environments. Since no official fix or removal by the vendor is mentioned, manual removal of these extensions and user awareness are recommended mitigation steps.

Reddit Discussion
Following my initial report on WaSteal, I ran additional infrastructure pivots using internal tooling and surfaced 57 more extensions tied to the same campaign.
Same operator, same backend, same exfiltration behavior. 183 extensions total, all still live on the Chrome Web Store.
