AttackIQ has released two new attack graphs in response to the CISA Advisory (AA25-203A) published on July 22, 2025, which disseminates known Interlock ransomware Tactics, Techniques, and Procedures (TTPs) and Indicators of Compromise (IOCs) identified through FBI investigations as recently as June 2025.
June 12, 2025
AttackIQ has released an updated attack graph in response to the recently revised CISA Advisory (AA23-352A) which disseminates Indicators of Compromise (IOCs) and Tactics, Techniques, and Procedures (TTPs) associated with the Play Ransomware group, identified through FBI investigations as recently as May 2025.
May 23, 2025
AttackIQ has released two new attack graphs that emulate the behaviors exhibited by DragonForce ransomware since its emergence in August 2023. Initially based entirely on the leaked LockBit 3.0 (Black) builder, it evolved with the introduction of a customized variant derived from the Conti V3 codebase. DragonForce operators may potentially be behind the recent cyber attacks that involved Marks & Spencer, Co-Op, and Harrods.
May 22, 2025
AttackIQ has updated an existing assessment template in response to the CISA Advisory (AA25-141B) published on May 21, 2025, which disseminates Tactics, Techniques and Procedures (TTPs) and Indicators of Compromise (IOCs), associated with threat actors deploying the LummaC2 information stealer malware, identified through FBI investigations as recent as May 2025.
May 8, 2025
AttackIQ has released a new attack graph emulating the behaviors exhibited by Termite ransomware since its emergence in November 2024. Termite is widely believed to be based on Babuk Ransomware, a defunct strain whose source code was leaked in 2021. While Babuk’s influence remains evident, particularly in encryption routines and general behavior, Termite distinguishes itself by aggressively targeting environment-specific vulnerabilities.
April 24, 2025
AttackIQ has released a new attack graph emulating the behaviors exhibited by Helldown ransomware since its emergence in August 2024. Helldown is operated by the eponymous and still largely undocumented adversary, which employs double extortion tactics by exfiltrating sensitive data prior to encrypting victim systems and threatening to leak the data on its Dedicated Leak Site (DLS)

February 26, 2025
AttackIQ has released a new attack graph emulating the behaviors exhibited by Akira ransomware since its emergence in March 2023. Akira operators provide victims the option to pay for either file decryption or data deletion rather than being forced to pay for both. Reported ransom demands range from 200,000 USD to over 4 million USD.
February 20, 2025

January 27, 2025
AttackIQ has released a new attack graph emulating the behaviors exhibited by Hunters International ransomware since its discovery in October 2023. Technical analysis suggests a realistic possibility that Hunters International may have been deployed by actors linked to the disrupted Hive operation. However, while it bears significant similarities, Hunters International is not a direct rebrand.
January 24, 2025

January 9, 2025
AttackIQ has released a new attack graph emulating the behaviors exhibited by Ako ransomware since its emergence in January 2020. Contrary to many ransomware strains that focus on individual workstations, Ako targets entire networks, maximizing its impact. It is considered a variant of MedusaLocker due to numerous shared traits, including its defensive behavior and its strategic isolation of specific machines for encryption.
