No, this is not original research, this isn't being uncovered now, and I'm not sure why this is being republished now in 2020. There have been detailed leaks since 1995 on cryptome.org and crypto mailing lists about CryptoAG, including details about the message format and the bits used to leak parts of the key (16 bit leak, IIRC). The CryptoAG story has tainted all Swiss-based crypto/security firms since 1994.
