LetsEncrypt, which offers free SSL certificates for encryption, is forced to revoke some certificates. The issue is related to a software bug in the management software Boulder, used for building the CA. Typically, the DNS CAA record check is carried out simultaneously with the domain ownership confirmation, and most subscribers receive the certificate immediately after verification, but the software developers have made it so that the verification result...
Hello. My name is Vanya, and I am a Java developer. It just so happens that I work a lot with PostgreSQL – I configure databases, optimize their structure, enhance performance, and I even play DBA on weekends. Recently, I've cleaned up several databases in our microservices and developed the java library pg-index-health, which simplifies this process, saves me time, and helps […]
Researchers from Soluble have discovered a new way to register domains with homoglyphs, visually similar to other domains but differing due to the presence of characters with different meanings. Such internationalized domain names (IDNs) can initially appear indistinguishable from domains of well-known companies and services, allowing their use for phishing, including obtaining valid TLS certificates for them. […]

After I finished the New Year's Olivier salad, I found myself with nothing to do, so I decided to download all the articles from Habr (and related platforms) to explore. There ended up being several interesting storylines. The first of these is the evolution of the format and themes of articles over the 12 years of the website's existence. For example, the dynamics of certain topics are quite indicative. Continuation — below the cut. The process […]

Since I did not want to write […]
