cell provider called - "optimizing my subscription," - but before we continue, I should read back the SMS TAN they sending me now. I really hope that they were scammers, and not genuine my cell provider. It would set a terrible precedent telling customers to pass TANs via phone

Is it normal for companies to wait with a CVE assignment until a fix is ready? Is it because the CVSS score is lower if a fix is available?

The .ZIP file format turned 35 this year - and is alive as ever. Your Android app? A ZIP. Your iOS app? Zip. OpenOffice document? A ZIP. Java Archive? ZIP. Your Microsoft Word Docx? A ZIP.
