Holy Bits, Coderperson!

February 25, 2019 by Marc Handelman in 51% Attack, Cryptocurrency, Cryptology, Information Security, Schadenfreude

via Mike Orcutt, reporting for the MIT Technology Review brings today's Must Read post to our attention on this beautiful Monday morning. Apparently, the highly touted immutability and repudiation-resistant Blockchain, is not completely immune to cleverly mounted attack methodologies.

Witness, if you will, the Twilight Zone of Blockhain, in which, the highly-touted cryptological database construct known as the Blockchain falls prey to not only it's proponents own hubris, but to the reckoning of all things crypto.

For, as we now know, if a cryptosystem can be attacked, the attack will be successful due to cryptocurrency susceptibility to 51% attacks, and dreaded smart-contract bugs. Enjoy the new crypto-flavor of Now! Feels a bit like schadenfreude right-about-now... H/T

Of so-called smart-contract honeypots... via Gerhard Wagner. H/T

"Hardly a week passes without large scale hacks in the crypto world. It’s not just centralised exchanges that are targets of attackers. Successful hacks such as the DAO, Parity1 and Parity2 have shown that vulnerabilities in smart contracts can lead to losing digital assets worth millions of dollars." - via Gerhard Wagner
