It targets critical infrastructure sectors including Government, Financial Services, Manufacturing, and Energy. AttackIQ has released an attack graph emulating BlackByte's TTPs, covering execution and defense evasion (disabling Windows Defender, modifying registry keys, disabling firewall profiles) and discovery/impact stages (ARP reconnaissance, Volume Shadow Copy deletion, AES-128/RSA-1024 file encryption). The emulation maps to MITRE ATT&CK techniques including T1053.005, T1562.001, T1562.004, T1490, and T1486, enabling security teams to continuously validate detection and prevention controls against this threat. ## Full article daily.dev links to this article rather than hosting it.
