🏛 Thieves brazenly used a furniture elevator to access a second‑floor window and stole historic jewels worth about €88 million from display cases at the Louvre in October 2025. French authorities say the alarms on the affected window and cases functioned as intended, but the theft prompted a comprehensive security review and urgent recommendations for new governance, extra perimeter cameras, and updated protocols. Confidential audits cited by Libération document chronic IT weaknesses since 2014 — systems running Windows 2000 and weak password hygiene, including a video server reportedly protected by the password "LOUVRE".

🚚 Proofpoint warns of a spear‑phishing campaign targeting North American freight firms that installs remote monitoring and access tools to enable cargo theft. Actors compromise broker load boards, insert themselves into carrier email threads, or pose as brokers to deliver signed installers that harvest credentials and establish persistent access. The attackers have deployed a range of RMM/RAS solutions (for example ScreenConnect, SimpleHelp, PDQ Connect, Fleetdeck, N‑able, and LogMeIn Resolve) and use them to bid on or reroute high‑value loads; Proofpoint urges blocking unauthorized RMMs, enforcing endpoint/network detection and MFA, disallowing external executables, and expanding phishing awareness training.

🔒 The Apache Software Foundation says there is no evidence that Apache OpenOffice was breached after the Akira ransomware gang claimed on October 30 that it had stolen 23 GB of corporate documents. The Foundation notes it does not maintain payroll-style employee records or the types of financial and identity documents described, and it has not received a ransom demand. An internal investigation so far has found no compromise and Akira has not published any of the alleged data.

🕸 The nascent Scattered LAPSUS$ Hunters (SLH) collective — a merging of Scattered Spider, LAPSUS$, and ShinyHunters — has repeatedly recreated its Telegram presence, cycling channels at least 16 times since August 8, 2025. The group markets an extortion-as-a-service offering to affiliates, targets organizations including those using Salesforce, and has teased a custom ransomware family called Sh1nySp1d3r. Trustwave SpiderLabs assesses SLH as blending financially motivated crime with attention-seeking hacktivism and sophisticated brand management.

🔒 Miljödata, an IT systems supplier for roughly 80% of Sweden's municipalities, disclosed an August 25 cyberattack that exposed personal data tied to 1.5 million people and included a 1.5 BTC extortion demand. The incident disrupted services across multiple regions and prompted immediate involvement from CERT‑SE, police and the Swedish Authority for Privacy Protection (IMY). Investigations will prioritize Miljödata's security and municipal data handling, with special attention to children's data and protected identities.

🔐 Nikkei disclosed that unauthorized actors accessed employee Slack accounts after an employee's computer was infected with malware and credentials were stolen. The breach exposed the names, email addresses, and chat histories of 17,368 registered users. Nikkei discovered the incident in September, enforced mandatory password resets, and voluntarily notified the Personal Information Protection Commission, stating that journalist sources and reporting data were not compromised.

🔎 Europol and Eurojust led a coordinated sweep from October 27–29 across Cyprus, Spain, and Germany that resulted in nine arrests tied to a cryptocurrency money‑laundering network accused of defrauding victims of €600 million (~$688 million). Authorities executed searches and seized €800,000 ($918,000) in bank funds, €415,000 ($476,000) in cryptocurrencies, and €300,000 ($344,000) in cash. Investigators say the group created dozens of fake crypto investment platforms and lured victims via social media ads, cold calls, fake news articles, and fraudulent celebrity testimonials. The scheme laundered proceeds using blockchain techniques and was disrupted after victim complaints spurred a cross‑border investigation.

🔍An international cryptocurrency investment and money‑laundering network has been dismantled in Europe after coordinated operations by French, Belgian and Cypriot authorities. Nine suspects were arrested across Cyprus, Germany and Spain between October 27 and 30, and investigators seized roughly €1.6m in cash, bank funds, crypto wallets and luxury items. French prosecutors say the group ran dozens of fake trading platforms and used social media, phone calls and sponsored fake news to target hundreds of victims, laundering at least $700m in crypto proceeds.

🔎 European authorities arrested nine suspected money launderers tied to a crypto investment fraud ring that stole over €600 million from victims across multiple countries. The coordinated raids on October 27 and 29 in Cyprus, Spain and Germany were led by Eurojust from The Hague. Investigators seized €800,000 in bank accounts, €415,000 in cryptocurrencies and €300,000 in cash. The suspects allegedly used dozens of fake investment platforms and social engineering — including social media ads, cold calls, fake news and celebrity testimonials — to recruit victims and then laundered proceeds using blockchain tools.

🔐 Microsoft Incident Response (DART) uncovered a covert backdoor named 'SesameOp' in July 2025 that leverages the OpenAI Assistants API as a command-and-control channel. The malware uses an obfuscated DLL loader, Netapi64.dll, and a .NET component, OpenAIAgent.Netapi64, to fetch compressed, encrypted commands and return results via the API. Microsoft recommends firewall audits, EDR in block mode, tamper protection and cloud-delivered Defender protections to mitigate the threat.

🛡️The Russian-linked threat group Curly COMrades abused Microsoft Hyper-V on Windows hosts to deploy a hidden, minimal Alpine Linux VM that hosted custom implants: CurlyShell (reverse shell) and CurlCat (reverse proxy). By using the Hyper-V Default Switch and naming the VM "WSL," outbound C2 traffic appeared to originate from the legitimate host IP, enabling evasion of host-based EDRs. The campaign — active since mid-2024 and observed by Bitdefender with help from the Georgian CERT — also employed PowerShell scripts for LSASS Kerberos ticket injection and Group Policy-based account creation, leaving few forensic traces. Organizations are advised to monitor unexpected Hyper-V activation, abnormal LSASS access or tampering, PowerShell GPO deployments, and to implement network-level inspection and layered defenses.

🛡️DragonForce, a ransomware operation built from leaked Conti source code, has restructured into a self-styled cartel that recruits affiliates and encourages branded variants. Researchers at Acronis report it retains Conti’s ChaCha20/RSA encryption, SMB-based network spreading, and multiple encryption modes while employing a hidden configuration system. Operators have pursued aggressive tactics — including defacing rival leak sites and aligning with access brokers like Scattered Spider — and have threatened victims with decryptor deletion and data leaks.

🔒 Three cybersecurity professionals have been indicted for allegedly operating an ALPHV/BlackCat ransomware affiliate network that attacked at least five U.S. companies between May and November 2023. Prosecutors named former Sygnia incident response manager Ryan Clifford Goldberg and negotiator Kevin Tyler Martin of DigitalMint, accusing them of exfiltrating data, encrypting systems, and demanding cryptocurrency extortion payments. An FBI affidavit describes encrypted dark‑web negotiations, multi‑hop transfers using privacy coins such as Monero, and meticulous spreadsheets that tracked ransoms, receipts, and wallet addresses. Charges include conspiracy to extort and intentional damage to protected computers, with potential forfeiture of crypto assets.

🏛 The Louvre has struggled for more than a decade with outdated software and unsupported Windows systems that control critical security infrastructure, French reports say. Audits in 2014 and 2017 found workstations running Windows 2000 and Windows XP, along with a video server still on Windows Server 2003 and weak, hard-coded passwords on surveillance applications. Procurement records also list multiple Thales systems as "software that cannot be updated." Authorities ordered governance and security reforms after a recent jewelry theft, though there is no indication the IT issues directly enabled that burglary.

🔒 Microsoft warns of an emerging scam targeting online payroll systems, in which attackers use social engineering to steal employee and administrator credentials. Those credentials are abused to reroute direct deposits into attacker-controlled accounts, and fraudsters may take extra steps such as changing contact details or suppressing notifications to delay detection. The advisory highlights how moving payroll online creates new avenues for account takeover and financial fraud, and urges employers and vendors to strengthen authentication, monitoring, and verification processes.

🛡️ Researchers at Microsoft disclosed a previously undocumented backdoor, dubbed SesameOp, that abuses the OpenAI Assistants API to relay commands and exfiltrate results. The attack chain uses .NET AppDomainManager injection to load obfuscated libraries (loader "Netapi64.dll") into developer tools and relies on a hard-coded API key to pull payloads from assistant descriptions. Because traffic goes to api.openai.com, the campaign evaded traditional C2 detection. Microsoft Defender detections and account key revocation were used to disrupt the operation.

🔒 Attackers are deploying a persistent backdoor using OpenSSH and a customized Tor hidden service to target defense-related organizations in Russia and Belarus. The Operation SkyCloak campaign uses weaponized ZIP attachments and LNK-triggered PowerShell stagers that perform sandbox evasion and write an .onion hostname into the user's roaming profile. Persistence is established via scheduled tasks that run a renamed sshd.exe and a bespoke Tor binary using obfs4, enabling SSH, SFTP, RDP and SMB access over Tor.

🔐 Balancer, an Ethereum automated market maker, has been hit by a sophisticated exploit of its V2 Composable Stable Pools, with estimated losses exceeding $120 million. The team says pools that could be paused have been placed into recovery mode while it works with leading security researchers to investigate. Early analysis suggests a 'rounding down' precision loss in the Balancer Vault calculations was exploited and amplified via the batchSwap function. Balancer confirmed V3 pools were not affected and warned users about related phishing scams.

🔒Rhysida, a known enterprise-focused ransomware gang, is distributing malware via malvertising on Microsoft's Bing that redirects users to fake download pages for common tools such as Microsoft Teams, PuTTY, and Zoom. Victims who download receive an initial access trojan called OysterLoader, which establishes a persistent backdoor and is signed with Microsoft-like certificates to appear legitimate. The campaign pairs obfuscation/packing to lower static detection with trusted code signing to bypass allow-lists and AV. Experts urge behavior-based EDR, certificate pinning, DNS filtering, and tighter certificate oversight.

🔒 Federal prosecutors have indicted three U.S. nationals accused of using BlackCat (ALPHV) ransomware to breach five companies between May and November 2023 and extort payments. The defendants—Ryan Clifford Goldberg, Kevin Tyler Martin, and an unnamed co‑conspirator—allegedly targeted firms in medical devices, pharmaceuticals, clinical care, engineering, and drone manufacturing. Two were employed by cybersecurity firms at the time; both employers say they cooperated with investigators.
