| Much thanks vice.com for a mention!
| Here I will tell you exactly how I investigate crypto hacks and security incidents, and describe methodology!
Usually in blockchain investigation I use tools first for manual analysis such as tenderly.co, ethtective.com, breadcrumbs.app, 9000.hal.xyz, dune.xyz, nansen.ai, , bloxy.info, github.com/naddison36/tx2uml, github.com/ApeWorX/evm-trace.
Use all of the tools from my list & this website! Almost all of the presented tools run a separate knowledge-base, YouTube blog and have a reports base, so be sure to check them out!
I seen also a rather unusual method - the use of VR, which will empower the first step: ethresear.ch/t/open-source-3d-and-vr-blockchain-visualizations/3297/2
Second, I try to set clusters to check them through Chainalysis or amlbot.com (my referral: use investigation regime only)). See more similar tools there. Use all of the tools from my list & this website!
As a third step, I check contracts/addresses through the impersonator, the unrekt.net or revoke.cash checker and other tools. As an example, tutela.xyz github.com/TutelaLabs tool can help in tacking funds behind TornadoCash
When investigating an incident, it is also important to conduct a classic OSINT (2) investigation, for example, if we are investigating a hack - it is necessary to check messages from chats, interview employees and eyewitnesses. Sometimes this yields data: www.1337pwn.com/how-to-investigate-cryptocurrency-crimes-using-blockchain-explorers-and-osint-tools/
