Additionally tracked below the title Pydomer, the ransomware household has been beforehand linked to assaults benefiting from Pulse Safe VPN vulnerabilities (CVE-2019-11510), Microsoft revealed in late March 2021, noting that it was the primary current ransomware household to capitalize on the ProxyLogon flaws.
Cybersecurity vendor Sophos described the Black Kingdom as “considerably rudimentary and amateurish in its composition,” with the attackers leveraging the ProxyLogon vulnerability to deploy internet shells, which had been then used to concern PowerShell instructions to obtain the ransomware.
It additionally mentioned the exercise bears all of the hallmarks of a “motivated script-kiddie.” Then later that August, a Nigerian menace actor was noticed trying to recruit staff by providing them to pay $1 million in Bitcoin to deploy Black Kingdom ransomware on firms’ networks as a part of an insider menace scheme.

Ransomware Assaults Surge as Payoffs Dwindle
The developments come as ransomware continues to be an enduring menace, albeit more and more fragmented and risky, as sustained legislation enforcement actions are inflicting main shifts in noticed ways. This contains the rising frequency of encryption-less assaults and the development of cybercriminals shifting away from conventional hierarchical teams in favor of a lone-wolf method.
“Ransomware operations have gotten more and more decentralized, with a rising variety of former associates selecting to function independently moderately than stay tied to established teams,” Halcyon mentioned.
“This shift is being pushed by a number of elements, together with elevated legislation enforcement coordination, profitable takedowns of main ransomware infrastructure, and a broader push by actors to keep away from attribution by way of model rotation or unbranded campaigns.”
Information compiled by Verizon exhibits that 44% of all analyzed breaches in 2024 concerned using a ransomware pressure, up from 32% in 2023. However there’s excellent news: Extra victims than ever are refusing to pay ransoms and fewer organizations are prepared to pay the ransom demanded.
“For the calendar yr 2024, the median ransom paid comes up as $115,000, which is a lower from $150,000 within the earlier yr,” Verizon mentioned in its 2025 Information Breach Investigations Report (DBIR). “64% of the sufferer organizations didn’t pay the ransoms, which was up from 50% two years in the past.”

The ransomware fee decision charge for the interval has been tallied at 27%, down from 85% in Q1 2019, 73% in Q1 2020, 56% in Q1 2021, 46% in Q1 2022, 45% in Q1 2023, and 28% in Q1 2024.
“Whereas assaults are assuredly nonetheless occurring and new teams proceed to spin up every month, the well-oiled ransomware machine that early RaaS teams constructed is plagued with issues that appear unlikely to resolve,” it added.
Regardless of these setbacks, ransomware exhibits no signal of stopping anytime quickly, with Q1 2025 witnessing 2,289 reported incidents, a 126% improve in comparison with Q1 2024, per Examine Level.

North America and Europe accounted for greater than 80% of the circumstances. Shopper items and companies, enterprise companies, industrial manufacturing, healthcare, and development and engineering had been the sectors essentially the most focused by ransomware.
“Ransomware incident volumes are reaching unprecedented ranges,” Dr. Darren Williams, Founder and CEO of BlackFog, mentioned. “This presents ongoing challenges for organisations coping with attackers centered on disruption, information theft, and extortion. Totally different teams will emerge and disband, however all of them concentrate on the identical finish objective, information exfiltration.”
