'"Hyundai predictably fails in attempting to secure their car infotainment system with a default key lifted from programming examples," writes Slashdot reader sinij. "This level of security is unfortunately expected from auto manufacturers, who also would like to sell you always-connected Car2Car self-driving automobiles." Cryptographer and security experience Bruce Schneier writes: "Turns out the [AES] encryption key in that script is the first AES 128-bit CBC example key listed in the NIST document SP800-38A [PDF]," writes an unidentified developer under the name "greenluigi1." Luck held out, in a way. "Greenluigi1" found within the firmware image the RSA public key used by the updater, and searched online for a portion of that key. The search results pointed to a common public key that shows up in online tutorials like "RSA Encryption & Decryption Example with OpenSSL in C." Two questions remain: 1.) How did the test key get left behind? 2) Was it by accident or design?' -- source: https://it.slashdot.org/story/22/08/22/227245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
