Week 20, 2020

Lazarus, Terpin, Upbit, BitcoinPaperWallet

Happy Bitcoin halving and welcome back to the Blockchain Threat Intelligence newsletter, the weekly digest of blockchain security news, tools, events, and threats. You may also be interested in /r/blocksec subreddit where I share many of the news below throughout the week.

Lot’s of money laundering activity this week where attackers have attempted to cash out their ill gotten gains or found innovative ways to obfuscate their source. North Korean hackers are at it again and more supercomputers commandeered to mine crypto. Also this week, more news about Michael Terpin’s quest to punish everyone involved in a 2018 heist. Oh and you may want to avoid using online paper wallet generators.




  • Bug Hunting with Crytic - a new smart contract security project by Trail of Bits. Crytic integrates with existing smart contract repositories to continuously execute some of ToB’s other tools like Slither and Echidna to produce customized reports.

That’s all for this week in blockchain security. A bit of trivia, the last block before Bitcoin reward halving contained a nice easter egg in the spirit of the genesis block: NYTimes 09/Apr/2020 With $2.3T Injection, Fed's Plan Far Exceeds 2008 Rescue. Stay healthy and see y’all next week!
