Dive Insight:
The FBI acknowledged a persistent difficulty it confronts in counting the “true number” of ransomware incidents — many attacks don’t get reported to law enforcement.
Phishing, remote desktop protocol exploitation and software vulnerability exploits remained the top initial infection vectors for ransomware attacks, the FBI said. Threat actors continued to use extortion as a tactic to pressure victims to pay the ransom or risk the release of stolen data.
Extortion crimes reported to the FBI remained flat compared to 2021, but down by nearly half from a peak in 2020. Extortion, not exclusive to ransomware, was the fourth-highest cybercrime type reported to the FBI last year, with more than 39,000 incidents reported.
