During the past year, Let's Encrypt has issued a total of 15,270 SSL certificates that contained the word "PayPal" in the domain name or the certificate identity.
Of these, approximately 14,766 (96.7%) were issued for domains that hosted phishing sites, according to an analysis carried out on a small sample of 1,000 domains, by Vincent Lynch, encryption expert for The SSL Store.
Security experts have warned of Let's Encrypt abuse
Lynch's analysis comes to confirm some of the fears voiced as early as 2015, around Let's Encrypt's early launch phase.
Encryption and infosec experts warned that by providing free SSL certificates; phishers, tech support scammers, and other malware authors would flock to obtain free certificates and move their operations on HTTPS domains.
The first of these security incidents was a malvertising campaign that used Let's Encrypt certs, unearthed by Trend Micro in January 2016. Since then, there have been isolated cases, here and there, but nothing to hint at a mass abuse. Nevertheless, security researchers started spotting more and more of Let's Encrypt's certificates on malicious sites.
Phishers started abusing Let's Encrypt certs last year
