You mean like the elliptic curve cryptography that they backdoored and then pressured the NIST in to backing so that millions of people's data was both available to them and also potentially at risk to any 3rd party to find out about it? The one that's specifically mentioned in the article?
"But the agency appears to have created its own back door into encrypted communications. The computer industry, both in the
United States and abroad, routinely adoptssecurity standards approved by the National Institute of Standards and Technology (NIST). But in 2006, NIST put its seal of approval on one pseudorandom number generatorâ"the Dual Elliptic Curve Deterministic Random Bit Generator, or DUAL_EC_DRBGâ"that was flawed. The potential for a flaw was first identified in 2007 by Microsoft computer security experts. But it received little attention until internal NSA memos made public by Snowden revealed that NSA was the sole author of the flawed algorithm and that the
agency worked hard behind the scenes to make sure it was adopted by NIST. "
Yes, beneficial to society indeed...
