Florida water agency latest to confirm cyber incident as feds warn of nation

A ransomware gang hit Florida's St. Johns River Water Management District as CISA warned of IRGC-linked CyberAv3ngers attacks on exposed Unitronics water-sector PLCs.

The St. Johns River Water Management District, which oversees Florida drinking-water supply planning, confirmed suspicious activity in its IT environment and said containment measures were implemented; a ransomware gang claimed the attack and shared samples of stolen data. Separately, CISA, FBI, NSA, EPA and Israel's INCD warned that IRGC-affiliated CyberAv3ngers are actively compromising Israeli-made Unitronics Vision Series PLCs in the water sector using default credentials since at least November 22. The group, motivated by opposition to Israel-linked products, defaces controller interfaces and could cause deeper cyber-physical effects. Shadowserver found at least 539 Unitronics PLC instances still exposed online, and CNN reported fewer than 10 US water facilities faced recent attacks.

Panzer Ransomware Targets Italian Manufacturers and Telecom Firms With ESXi-Ready RaaS

New Panzer ransomware-as-a-service operation lists Italian firms Doimo Cucine and NTE Italia as victims, offering encryptors for Windows, Linux, FreeBSD, and ESXi.

Panzer, a ransomware-as-a-service operation that surfaced August 5, listed a kitchen manufacturer in Treviso (Doimo Cucine) and a telecommunications engineering firm in Catanzaro (NTE Italia) among alleged victims, claiming 30 GB and 16 GB of stolen data respectively. The group advertises encryptors for Windows, Linux, FreeBSD, and VMware ESXi, a Tox-based affiliate recruitment process with screening, an affiliate dashboard, and an 80/20 revenue split. Neither victim had publicly confirmed the incidents when researcher Andrea Fortuna's report was published, and the group's first access method and payload have not been independently analyzed. Panzer posted victims across 11 countries as claimed Italian ransomware incidents reached 212 by September 6, already above 2025's full-year total of 169.

Berlin Refuses to Pay Hackers Who Stole Data From the City's State Network

Berlin refuses ransom demands after Rhysida claimed stealing 5.79 TB from the city-state network, including mobility department data on 12,076 individuals.

Berlin's state government confirmed an extortion attempt following the August compromise of its state administrative network and said it will not pay. Forensics found data exfiltrated from the Senate Department for Mobility, Transport, Climate Protection and Environment between August 7 and 12, 2026; Rhysida's leak site claims 5.79 TB, 1.44 million files, and personal data on 12,076 individuals. State criminal police, prosecutors, and federal authorities are investigating, and officials say the September 20 Abgeordnetenhaus election environment remains unaffected. Separately, Manchester Airports Group confirmed theft of customer data including emails, phone numbers, and vehicle registrations across three airports.

U.S. Bank says breach claims related to fourth

LockBit claimed data theft from U.S. Bancorp, but the bank attributes it to a fourth-party breach at a contractor's third party, with no impact on its own systems.

LockBit added U.S. Bancorp to its leak site and threatened to release stolen data within two weeks, but the bank investigated and attributed the claims to a fourth-party incident outside its environment. U.S. Bancorp stated there is no evidence its systems, networks, or data repositories were compromised and reported the matter to law enforcement. The bank is the seventh largest in the United States, and LockBit provided no samples to substantiate the claim. The gang, previously subject to a 2024 law enforcement takedown, earned $252.4 million in ransoms through 353 attacks from 2022 to 2024 according to the U.S. Treasury.

Medusa ransomware tallies hundreds of new victims, says updated advisory on group’s tactics

CISA, FBI, and HHS updated their Medusa ransomware advisory, reporting over 500 victims and detailing the gang's access-broker and exploit tactics.

A joint advisory update from CISA, the FBI, and HHS expands the March 2025 Medusa guidance, drawing on a year of FBI investigations. The ransomware-as-a-service group's known victim tally grew from more than 300 to more than 500 between March 2025 and April 2026, with the Healthcare and Public Health sector frequently hit. Medusa pays access brokers $100 to $1 million, has exploited flaws such as Fortra GoAnywhere and BeyondTrust vulnerabilities, and leverages newly announced exploits within 24 hours, sometimes a week before public disclosure. The group uses living-off-the-land techniques, remote monitoring and management software, and RDP for lateral movement, and has been linked to actors including Microsoft-tracked Storm-1175 and North Korean hackers targeting healthcare.

Ransomware attackers are zeroing in on mid-market companies

Black Kite found mid-market firms were 73% of disclosed ransomware victims in North America and Europe from January 2023 to June 2026.

Black Kite analyzed 13,336 publicly disclosed ransomware and data-extortion incidents with known revenue between January 2023 and June 2026, finding mid-market companies (annual revenue $10M-$1B) accounted for 73% of victims in North America and Europe, consistently between 72% and 75%. Manufacturing was the most affected sector, followed by professional, scientific, and technical services and construction. Of more than 120,000 assessed mid-market organizations, 54.7% had at least one significant patch-management issue on a public-facing system, over a quarter had a known-exploited vulnerability, and nearly one-third had stealer-log credential findings.

AI agents carried out every step of this ransomware attack – then left the victim an 80-page security audit

Unit 42 says a human attacker used AI agents to execute a full ransomware intrusion in under 10 hours, leaving the victim an 80-page security audit.

Palo Alto Networks Unit 42 incident responders report a human ransomware operator used frontier AI models and agentic attack frameworks to breach an enterprise in under 10 hours, work that normally takes human operators around two weeks. AI agents performed reconnaissance, breached a public API endpoint to tunnel into the network, scraped code repositories for hard-coded tokens and service passwords, then used them to steal master administrative credentials from the secret-management system for root access. Specialist pivot agents validated access to cloud, identity, CI/CD, container and SaaS environments, and the attacker hijacked CI/CD workflows to steal cloud keys and turn the victim's cloud AI services into post-compromise infrastructure. The agents left an 80-page audit detailing dozens of exploited findings.

Berlin says it won’t pay ransom after hackers steal government data

Berlin refuses ransom as Rhysida ransomware group claims theft of 5.79 TB of government data ahead of September 20 elections.

The Rhysida ransomware group claimed responsibility for stealing 5.79 TB of data from Berlin's government network, including 46,500 contracts, emails, phone numbers, passwords and classified information, and listed it for auction starting at 30 bitcoin (~$2.3 million). Berlin discovered the breach in mid-August, disconnected two ministries from the state network on August 14, and refused to pay the ransom; authorities have not officially attributed the attack. Data is believed taken between August 7 and 12, and district services such as housing benefit processing were disrupted. Officials said election infrastructure is protected ahead of the September 20 House of Representatives vote, and state IT provider ITDZ Berlin was unaffected.

Harley-Davidson Alleged Breach – CL0P Ransomware Adds Motorcycle Maker to the List

CL0P ransomware group listed Harley-Davidson on its extortion leak site, claiming a compromise; the motorcycle maker has not confirmed any breach.

The CL0P ransomware operation added Harley-Davidson to its public extortion portal, a listing highlighted by the ransomNews monitoring account on September 10, 2026. Harley-Davidson has not confirmed any compromise, and the initial access method, affected business unit, timing, and volume of stolen data remain unknown, with no sample files or technical indicators published. The article stresses that leak-site listings alone do not confirm a breach and can serve as negotiation pressure in double-extortion schemes. If verified, stolen data could fuel downstream phishing, BEC, credential-stuffing, and invoice fraud targeting dealers, suppliers, and customers.

Aurora Ransomware Operators Use Cursor AI in Attacks Against 10 Targets

Aurora ransomware operators used Cursor AI running Claude Sonnet to plan and execute intrusions against dozens of organizations in nine countries.

CloudSEK and Gambit Security analyzed exposed infrastructure tied to the Russian-speaking Aurora (Aur0ra) group, revealing months of activity against more than 20 organizations across nine countries between April and July 2026, with 33 victims listed by Ransomware.Live. The operator used the Cursor agentic coding assistant to plan attacks in Russian, including an AD CS exploitation plan, and Gambit observed Cursor Agent (running Anthropic's Claude Sonnet) performing hands-on exploitation tasks such as Nmap scanning, NetExec enumeration, NTLM relay, and certificate attacks against 10 targets. Attacks begin with email bombing plus IT help desk vishing via Xray-core, followed by SMB/LDAP/WinRM/RDP lateral movement, log clearing, Defender disabling, and exfiltration; the Windows and Linux/ESXi encryptors are built from a single Zig codebase, with shadow copy deletion and VM-killing before encryption.

New Android Ransomware Records Screens, Steals OTPs and Secretly Takes Photos of Victims

Zimperium uncovered Mantax Otax, an Android ransomware that encrypts files, records screens, steals OTPs, and secretly photographs victims.

Zimperium reported a new Android threat, Mantax Otax, that combines ransomware with surveillance: it encrypts files with AES and adds a .enc extension on Android 9 and older, while abusing MediaProjection for screenshots and MP4 screen recording and using hidden camera previews to photograph victims. The malware intercepts SMS one-time passwords, WhatsApp and Telegram data, and lock-screen PINs through Accessibility abuse and a fake system-lock overlay, and can negotiate ransoms via an on-screen chat. Malicious APKs are hosted on third-party file-sharing services, and researchers linked the activity to Indonesian threat actors, with C2 dynamically retrieved from a GitHub repository (apimantax[.]otax[.]fun). A second variant adds WebSocket communications, app blocking, full-screen overlays, and remote text-to-speech messages.
