"Unix Support Group" event
According to secondary sources research,
a well-known, published author
deployed a compiler trojan attack on the Unix login command by
advertising a non-backwards-compatible feature to Bell Labs' Unix
Support Group, making its way to the login command within a month.
Impact
None as reported.
Type of compromise
Compiler backdoor, possibly compounded with human elements.
