A suspected ransomware affiliate is posing as a ransomware recovery service called "Ransom Busters," contacting victims before the attacks become public and claiming it can provide decryption keys and delete stolen data for a fee. GuidePoint Security's Research and Intelligence Team (GRIT) disclosed this activity after responding to several recent ransomware attacks in which victims received emails from Ransom Busters offering to help recover from the attack. The messages were suspicious because they were sent to victims before the attacks became public, raising questions about how they knew about the cyberattacks in the first place. Ransom Busters claimed it exploited vulnerabilities in administrative panels used by ransomware-as-a-service (RaaS) operations, giving it access to encryption keys and data stolen from victims.

Japanese cloud and data center service provider Sakura Internet disclosed that hackers accessed its sales management system, where customer contract and membership information is stored. In an update today to the initial notification from Monday, the company says the incident may have impacted up to 1,360,563 member accounts.

Cybersecurity researchers have disclosed details of a remote Spectre attack against Cloudflare Workers that leaked a JSON Web Token (JWT) from a co-located Worker in the production environment at up to 12 bits per second, 360 times the rate of an earlier attack demonstrated in 2021. The end-to-end experiment used an attacker Worker and a victim Worker controlled by the researchers,
Cybersecurity researchers at Hunt.io have disclosed details of a campaign that they say compromised more than 14,530 Dahua devices between June 17 and July 22, 2026, using credential attacks, two authentication-bypass flaws, and a peer-to-peer (P2P) relay technique.
