🔒 Applying zero trust to the storage layer is no longer theoretical — it is now essential to ensure recovery. The author describes ransomware incidents, including Change Healthcare in February 2024, where attackers deliberately targeted backups and recovery points, exposing storage as a primary attack surface. He recommends three operational principles — control where data is touched, control who and when, and make critical backups immutable — and ties those measures to governance, policy-as-code, and executive outcomes.

🔒 The municipality of Hoppegarten in Brandenburg is still recovering from a hacker attack that forced its IT systems to be shut down on August 10. As of September 22, remediation remains ongoing, with central services such as email, telephone, and citizen services restored. Communication with subordinate institutions, including schools and daycare centers, remains disrupted. Authorities say the State Criminal Police Office is investigating a suspected attempted data encryption, possibly tied to an extortion attempt.

🛡️ Allianz warns that cybercriminals are increasingly shifting focus from well‑defended large organizations to smaller, less secure firms and to regions beyond the US and Europe. The insurer's Cyber report says customer losses in H1 2025 were about half those in H1 2024, even as active ransomware groups may have risen by roughly 50%. Double extortion and data theft now account for a growing share of large losses, and attackers often exploit third‑party IT providers to reach hardened targets.

🔒 ReliaQuest's Threat Spotlight (June–August 2025) reports average attacker breakout time — the period from initial access to lateral movement — has fallen to 18 minutes, with one Akira incident taking just six minutes. The vendor warns adversaries are becoming faster and more adept at bypassing endpoint protections, noting an increase in ransomware using the SMB protocol (from 20% to 29%). Drive-by compromise was the leading initial vector at 34%, and USB-based malware, notably Gamarue, is resurging due to weak policy enforcement and inconsistent endpoint controls.

🛫 Over the weekend several major European airports experienced check-in and boarding disruptions after a ransomware attack on the external vendor Collins Aerospace. Attackers targeted the MUSE multi-airline check-in system, forcing manual processing of thousands of passengers and causing delays and cancellations to more than 100 flights. Airports affected included Heathrow, Brussels and Berlin Brandenburg, with only minor impact reported in Cork and Dublin. Authorities and the vendor are investigating while restoration efforts continue.

🔒 Picus Security's Blue Report 2025 shows ransomware continues to outpace defenses: overall prevention fell from 69% to 62% year-over-year, while data exfiltration prevention collapsed to just 3%. Both established families (BlackByte, BabLock, Maori) and emerging strains (FAUST, Valak, Magniber) bypass controls using credential theft, fileless techniques and staged execution. Picus recommends continuous Breach and Attack Simulation (BAS) to validate controls, deliver actionable fixes, and provide measurable evidence of readiness.

🔒 The BMW Group has been named on the darknet by the Everest ransomware group, which claims to have stolen critical BMW audit documents, according to screenshots reported by Cybernews. The gang placed two countdown timers on its onion site—one running to Sept. 14 and a second giving BMW 48 hours to make contact. BMW has not commented and the extortionists have not confirmed whether customer or personal data were taken; Cybernews researcher Aras Nazarovas advises waiting for a published sample to assess the scope.

🔒 Researchers at ESET have identified a new bootkit-style ransomware named HybridPetya that targets the NTFS Master File Table (MFT) and can override UEFI Secure Boot to install a malicious EFI component. The malware abuses a patched vulnerability (CVE-2024-7344) in a signed Microsoft EFI file to load an unsigned payload called cloak.dat. The installer replaces the Windows bootloader, triggers a crash and, on reboot, the compromised loader executes a bootkit that encrypts the disk with Salsa20, using a fake CHKDSK message to conceal activity. ESET observed a ransom demand of €850 in Bitcoin but regards the sample as likely a research proof-of-concept.

🔒 US and UK authorities have charged two UK-based teenagers linked to the Scattered Spider cybercrime group in connection with multiple high-profile intrusions. Thalha Jubair, 19, and Owen Flowers, 18, face US and UK charges including conspiracy to commit computer fraud, wire fraud, money laundering and offences under the UK Computer Misuse Act. Authorities allege extensive social engineering, ransomware extortion and transfers of victim cryptocurrency, with investigators attributing at least $115m in ransom payments to the group. The arrests follow a multinational probe and earlier detentions of other alleged members.

🔒 Zscaler's annual ThreatLabz Ransomware Report (April 2024–April 2025) warns of a marked rise in extortion-focused attacks: incidents increased 146% year-over-year while exfiltrated data grew 92%. The vendor attributes this to a strategic shift from pure encryption to data theft and public shaming, with criminals using stolen files as leverage. Researchers also report that generative AI is increasingly incorporated into attackers' playbooks to enable more targeted and efficient campaigns. The U.S. accounted for half of all recorded attacks, Germany saw a nearly 75% rise and is the EU's most affected country, and the most-targeted sectors were manufacturing, technology and healthcare.

🔒 Insight Partners disclosed a ransomware attack that occurred around 25 October 2024 but was first detected on 16 January 2025. The firm says a sophisticated social engineering attack enabled a threat actor to exfiltrate data and encrypt servers before being expelled the same day. About 12,657 individuals may be affected; the firm offers free identity-theft protection and urges password resets and MFA.

🔒 Small and medium-sized businesses are increasingly targeted by ransomware gangs that exploit weak defenses, offer Ransomware-as-a-Service, and adapt tactics with AI-driven tools. RaaS industrialization and discoveries like ESET's PromptLock demonstrate how attackers can scale reconnaissance, exploitation and social engineering. SMBs face double-extortion, DDoS and coercive pressures while repeat payments remain an issue despite a decline in aggregate crypto payouts. Practical defenses—Zero Trust, timely patching, reliable backups, EDR/MDR and tested incident response—can materially reduce risk.

🔒 Insight Partners is notifying thousands of people after a ransomware incident in which a threat actor gained network access via a sophisticated social engineering attack. The attackers reportedly exfiltrated sensitive data — including banking and tax records, personal information of current and former employees, and details related to limited partners, funds, management companies, and portfolio companies — before encrypting servers on January 16, 2025. The firm says formal notification letters and complimentary credit or identity monitoring are being mailed; if you do not receive a letter by the end of September 2025, your personal data was determined not to be impacted. State filings indicate 12,657 individuals were affected, and no group has publicly claimed responsibility.

🔍 Huntress analysts observed an uptick in attacks that combine classic ClickFix social engineering with more advanced deployment techniques over the past fifteen business days. A fake AnyDesk installer used a Cloudflare Turnstile lure that opened Windows File Explorer via the search-ms protocol to deliver an LNK payload disguised as a PDF and install an MSI that dropped MetaStealer. Separately, operators deployed Cephalus ransomware using DLL sideloading through the legitimate SentinelOne host binary, illustrating evolving tradecraft that mixes manual user interaction and technical evasion.

🔒 ESET researchers have identified a new ransomware strain named HybridPetya that mimics the Petya/NotPetya family while adding UEFI-targeting capabilities. The malware weaponizes CVE-2024-7344 to bypass UEFI Secure Boot on unpatched systems, enabling persistent bootkit-style compromise. HybridPetya is not currently observed spreading in the wild but represents at least the fourth known bootkit with Secure Boot bypass functionality.

🔒 Researchers at ESET have identified HybridPetya, a bootkit-style ransomware that mimics Petya/NotPetya by targeting the NTFS Master File Table (MFT). Unlike destructive predecessors, HybridPetya functions as true ransomware and can reconstruct victim decryption keys from an installation key, with an analyzed sample demanding €850 in Bitcoin. The threat bypasses UEFI Secure Boot by exploiting CVE-2024-7344 in a Microsoft-signed EFI component to load an unsigned cloak.dat, replace the Windows bootloader, crash the system to force a reboot, and run prior to OS startup to encrypt the disk with Salsa20 while displaying a fake CHKDSK message.

🔒 ESET Research identified HybridPetya on VirusTotal in February 2025, with filenames implying a connection to the destructive NotPetya outbreak. The strain encrypts the NTFS Master File Table using Salsa20 and deploys a UEFI bootkit on the EFI System Partition to ensure firmware‑level persistence. One variant exploits CVE-2024-7344 to bypass UEFI Secure Boot via a signed but vulnerable Microsoft component, yet retains a working decryption mechanism for victims. Analysts found no signs of self-propagation like NotPetya, but the combination of pre-boot compromise and MFT encryption raises significant concern.

🔒 A newly identified ransomware group called Yurei is conducting double-extortion attacks, encrypting files and exfiltrating sensitive data before demanding payment. First observed by Check Point Research on September 5, Yurei has targeted organizations in Sri Lanka, India and Nigeria and may have ties to Morocco. Built largely from open-source Prince-Ransomware code, the malware encrypts each file using per-file ChaCha20 keys protected with ECIES, appending a .Yurei extension, and attempts to provide a ransom page and .onion contact. Although the early variant omits some operational features (for example it fails to set a ransom wallpaper and does not remove Windows shadow copies), the group still threatens publication of stolen data to pressure victims.

🔒 HybridPetya is a newly identified UEFI bootkit that can bypass Secure Boot by exploiting CVE-2024-7344, enabling installation of malicious components into the EFI System Partition. ESET located a sample on VirusTotal and describes it as possibly a proof-of-concept, research project, or an early-stage criminal tool. The bootkit replaces the Windows bootloader, forces reboots to execute at startup, encrypts MFT clusters with Salsa20 while showing a fake CHKDSK, and then presents a ransom screen demanding a Bitcoin payment and a 32-character key to restore the bootloader and decrypt data.

🛡️ Yurei ransomware emerged on September 5, quickly claiming victims in Sri Lanka, India and Nigeria within its first week. The payload is largely copied from the open-source Prince-Ransomware project, illustrating how easily attackers can deploy commodity code. Although technical flaws allow partial recovery, Yurei focuses on data theft and public exposure to coerce payments. Early indicators point to links with Morocco, signaling a geographically shifting threat landscape.
