No abuse reports filed yet — this domain is waiting for the next cycle of our automated abuse-reporter. ## TIMELINE ---------------------------------------------------------------- Domain registered: 2026-04-18 (per WHOIS / CT — may reflect a renewal or transfer date, not first-ever registration) First detected: 2026-04-18 22:22:15 UTC (by PhishDestroy tracker) Last verified: 2026-04-21 16:09:03 UTC Current status: ACTIVE / observable ## EXTERNAL CORROBORATION (third-party evidence) ---------------------------------------------------------------- URLScan.io: https://urlscan.io/result/019da208-ec00-705a-9145-fa977723a891/ Wayback Machine: https://web.archive.org/web/*/learn-extension-base-up.pages.dev crt.sh CT logs: https://crt.sh/?q=%25.learn-extension-base-up.pages.dev Google transparency: https://transparencyreport.google.com/safe-browsing/search?url=learn-extension-base-up.pages.dev AlienVault OTX: https://otx.alienvault.com/indicator/domain/learn-extension-base-up.pages.dev URLhaus: https://urlhaus.abuse.ch/host/learn-extension-base-up.pages.dev/ ## ANALYST NARRATIVE ---------------------------------------------------------------- [Generated: 2026-04-18 22:24:17 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.] learn-extension-base-up.pages.dev poses a risk of credential theft, which means it tries to trick users into revealing sensitive login information such as usernames, passwords, or other account details. This type of cyber threat can lead to unauthorized access to personal, financial, or work-related accounts, which may result in identity theft or financial loss. Users should be cautious when interacting with this site and avoid providing any personal credentials. PhishDestroy's analysis found that learn-extension-base-up.pages.dev currently has zero detections out of 95 antivirus engines on VirusTotal, suggesting it may be a newly emerging threat or designed to avoid detection. The domain is actively registered through Cloudflare, Inc., a well-known registrar and content delivery network, and it uses an SSL certificate issued by Google Trust Services, which could give a false sense of security. The domain resolves to IP address 188.114.97.3 and remains active, which indicates ongoing risk. The site's registration date and other historical data were not specified, but the low VT detection count and Cloudflare registration are important technical markers. If you have visited learn-extension-base-up.pages.dev, immediately avoid entering any login or personal information. If you suspect you may have already shared credentials, change your passwords on affected accounts as soon as possible and enable two-factor authentication where available. Monitor your accounts for any suspicious activity and consider running a security scan on your devices. Avoid clicking on any links or downloading files from this domain. Staying vigilant and reporting suspicious websites to your security provider can help protect you from evolving credential theft scams. ## EVIDENCE HASHES ---------------------------------------------------------------- TLS cert SHA-256: 7dda1cb1eb6f3820b82e5c02c5b04153e9e95abee357519e3ef01d252c1ea427 ## SCORING METHODOLOGY ---------------------------------------------------------------- Composite score is NOT derived from VirusTotal alone. PhishDestroy aggregates: - VirusTotal positive ratio - Public blocklist consensus (MetaMask, ScamSniffer, OpenPhish, PhishTank, URLhaus, CryptoFirewall, SEAL, Polkadot, Enkrypt, Phishunt, DiscordPhishing, PhishingDB) - Cloaking detection (HTTP 666 or rendering delta between bot and real visitor) - DNS-filter consensus (Quad9, CleanBrowsing, NextDNS, AdGuard, Cloudflare, etc.) - AlienVault OTX pulses + Cloudflare Radar + Google Safe Browsing - URLScan / URLQuery verdicts - Brand-impersonation heuristics (DOM analysis of forms, logos, wording) - Known phishing-kit fingerprinting (favicon hash, JS obfuscation signatures) - Wallet-drainer family classification (Angel, MS, Rainbow, Pink, Inferno, ...) - Free-TLS vs paid-cert ratio (throwaway infrastructure signal) - Registrar/hosting abuse history (this registrar's track record) - Human researcher sign-off (volunteer takedown team) A domain present in our database is ALREADY flagged. A low VT count by itself does NOT mean the domain is safe — new scam domains routinely show 0/95 VT for their first 7–30 days while actively draining wallets. Always cross-reference the composite score and the individual indicators above, not just VT. ## CORRECTIONS / APPEALS ---------------------------------------------------------------- Full HTML report: https://phishdestroy.io/domain/learn-extension-base-up.pages.dev/ JSON API: https://api.destroy.tools/v1/check?domain=learn-extension-base-up.pages.dev Appeal a flag: https://phishdestroy.io/appeals/ (responded to within 48 hours, FP rate <0.01%) Submit a report: https://t.me/PhishDestroy_bot About PhishDestroy: volunteer-driven open-source threat-intelligence platform.
