2) Why the reporting uptick, you ask? No surprises there: the second half of 2021 was effectively the world post-Colonial Pipeline, when ransomware became a household term. To boot, FINCEN issued some new reporting guidance in the second half of the year.

FinCEN: US financial firms processed ~$1.2B in likely ransomware payments in 2021, up almost 3x YoY; ~75% of H2 2021 ransomware incidents were linked to Russia

- U.S. banks and financial institutions processed more than $1 billion in potential ransomware-related payments in 2021.

Amid the flashy numbers in the new FINCEN report on 2021 ransom payments, I want to highlight three things: 1) the 1.2Bn figure is *reported* payments last year, many of which back to 2020. In part, it's actually a good news story about reporting! https://www.fincen.gov/...

3) Curious for some reactions to FINCEN's linking 75% of all attacks to Russian groups. There is clearly a Russia problem, yes. But the criteria for that “attribution” is pretty unscientific (Russian-language code, advertised on Russia forums or CIS keyboard locks). Thoughts?
