MedusaLocker RaaS Recruits Penetration Testers Globally

🔒 MedusaLocker, a ransomware-as-a-service (RaaS) group active since 2019, has posted a dark web job advert openly recruiting penetration testers and insiders who already have direct access to corporate networks. The advert explicitly instructs applicants not to apply unless they possess network access, signalling a preference for initial access brokers and company insiders. CISA previously linked MedusaLocker to exploitation of RDP vulnerabilities, and the group’s tactic highlights the blurred line between legitimate pentesting and criminal activity. Organisations should prioritise layered defenses, authorised penetration testing, and strict controls over remote access and privileged accounts.

Analyzing organizational traffic to Leakzone forum

🔍 UpGuard examined a leaked Elastic index containing 22 million client requests to Leakzone.net covering 28 days in June–July 2025. By mapping source IP metadata to known organizations, investigators identified traffic originating from universities, government networks, and private companies, including security vendors and large technology firms. Traffic patterns ranged from steady, automated scanning from services like Censys and SEMRush to bursty, human-like spikes from university and government networks, but the logs do not include request content, so intent remains uncertain.

Malvertising Campaign Delivers PS1Bot Multi-Stage Malware

🔍 Cisco Talos reports an active malvertising campaign delivering a multi-stage PowerShell/C# malware framework dubbed PS1Bot. The modular framework executes modules in-memory to minimize artifacts and supports information theft, keylogging, screenshot capture and cryptocurrency wallet exfiltration.

US Seizes $1.09M in Bitcoin From BlackSuit Gang Takedown

💰 The US Department of Justice announced it seized US $1,091,453 in cryptocurrency linked to the Russian-operated BlackSuit ransomware group following an international takedown of servers, domains and the gang's dark web extortion site. The recovered funds derive from a 49.3120227 Bitcoin ransom payment on or about April 4, 2023; that payment was originally worth US $1,445,454.86. Law enforcement partners in the United States, United Kingdom, Canada, Germany, Ireland and France collaborated on the operation that seized four servers and nine domains on July 24, and the frozen funds were identified after repeated deposits and withdrawals that ended with an exchange freeze in January 2024.

Full PowerShell RAT Campaign Targets Israeli Organizations

🔒 The FortiMail Workspace Security team uncovered a targeted intrusion campaign that abused compromised internal email to deliver a multi-stage, fully PowerShell-based Remote Access Trojan targeting Israeli organizations. Phishing links redirected users to a spoofed Microsoft Teams page that instructed victims to press Windows+R, paste an obfuscated Base64 loader, and execute a PowerShell IEX fetch from a hard-coded C2 (hxxps[:]//pharmacynod[.]com), which in turn staged scripts and a compressed, in-memory RAT. The operation uses layered obfuscation, native Windows APIs, and living-off-the-land techniques to enable remote access, surveillance, persistence, lateral movement, and data exfiltration; Fortinet protections detect and block this activity.

TeaOnHer App Replicates Tea's Functionality and Breaches

🛡️ TeaOnHer, a recent iOS knock‑off of the controversial dating app Tea, has been found exposing sensitive user data. TechCrunch reported government IDs, driving licences and selfies accessible via a public web endpoint with no authentication, and the app appears to copy wording and features from the original. Newville Media did not respond to disclosure attempts, and an exposed admin credential pair was found on the company server. Until these failures are addressed, users should avoid Tea-related apps.

Ransomware Forces German Insurance Firm into Bankruptcy

⚠ A ransomware attack attributed to the Royal group forced German insurer Einhaus Gruppe into insolvency after encrypted systems and locked servers halted operations. The spring 2023 incident left printers displaying a takeover message, prevented staff access to critical data, and generated a mid-seven-figure business disruption. Einhaus paid a ransom of roughly US $230,000, but prosecutors later seized cryptocurrency allegedly tied to the perpetrators, and the withheld funds impeded restructuring efforts and helped drive the company into bankruptcy.

Ukraine Claims Hack of Russia's New Nuclear Submarine

🔐 Ukraine's Defence Intelligence agency (HUR) says its hackers exfiltrated classified files and technical documentation related to the newly commissioned Russian nuclear ballistic missile submarine Knyaz Pozharsky. Leaked materials, posted on Telegram, reportedly include combat manuals, schematics of combat and survivability systems, crew lists with qualifications, and operational schedules. Russian authorities have not commented and independent verification by Western intelligence or cybersecurity experts is still pending.

Arrest in Raid on XSS Forum: Who Was Detained and Why

🔍 Europol and Ukrainian authorities announced the arrest of a 38-year-old suspect tied to the Russian-language XSS crime forum after a July 22, 2025 operation led by French investigators. Authorities say the detainee served as a trusted third party, arbitrating disputes and assuring transaction security for members linked to multiple ransomware groups. Reporting traces forum activity and multiple domain registrations tied to the handle 'Toha', but investigation suggests the arrested man is likely Anton Medvedovskiy rather than alternate identities circulated online. The takedown yielded Jabber server logs and forum backups, prompting a wary, contested relaunch.

Thai Hospital Fined After Patient Records Used as Wrappers

📄 A Thai hospital was fined after more than 1,000 patient records, sent for destruction, were found being used as street-food wrappers for crispy crepes. Thailand’s Personal Data Protection Committee (PDPC) determined the documents leaked following handling by a contracted disposal firm that stored them at a private residence. The hospital was fined 1.21 million baht and the disposal business owner received a separate penalty. The episode highlights failures in secure disposal and vendor oversight.

Project AK47 Linked to SharePoint ToolShell Exploits

🔍Unit 42 links a modular malware suite dubbed Project AK47 to SharePoint exploitation activity observed alongside Microsoft’s ToolShell reporting. The toolset includes a dual-protocol backdoor (AK47C2 with dnsclient and httpclient), a ransomware family (AK47 / X2ANYLOCK), and DLL side‑loading loaders. Analysts found high-confidence overlaps with Microsoft’s Storm-2603 indicators, evidence of LockBit 3.0 artifacts in an evidence archive, and a matching Tox ID on a Warlock leak site. Recommended actions include applying patches for the referenced SharePoint CVEs and enabling updated protections from endpoint, URL, and DNS defenses.

North Korea’s IT worker scheme infiltrating US firms

🔍 Thousands of North Korean IT workers have used stolen and fabricated US identities to secure roles at Western companies, funneling hundreds of millions of dollars annually to Pyongyang’s military programs. They leverage AI for resumes and cultural coaching, faceswap and VPN tools for video calls, and remote-access setups tied to US-based "laptop farms" run by facilitators who launder paychecks and ship company-issued machines abroad. Recent DOJ raids and the 102-month sentence for Christina Marie Chapman highlight legal, financial and national security risks, including potential sanctions violations.

Scammers Flood Social Platforms with Fake Gaming Sites

🔍 Fraudsters are promoting hundreds of polished fake gaming sites across Discord and other social platforms, falsely claiming partnerships with influencers and offering a $2,500 'promo code' to lure users. Visitors create free accounts to play sleek casino-style games (for example gamblerbeast[.]com's B-Ball Blitz), but cashouts are blocked and victims are prompted for a cryptocurrency 'verification deposit' and repeated payments. Investigators, including a Discord researcher and the threat-hunting firm Silent Push, linked a shared chat API key to at least 1,270 active domains and found centralized wallets, AI-assisted support, and network-wide tracking that make these scaled scams efficient and hard to report.

iPR Data Exposure: 477,000 Media Contacts and Keys

🔒 UpGuard researchers discovered a publicly accessible Amazon S3 bucket belonging to iPR Software, containing backups, internal documentation, and a dataset of approximately 477,000 media contacts. The collection included over 35,000 hashed passwords, a 17 GB MongoDB backup that expands substantially when restored, and credentials for services such as Twitter and a MongoDB hosting provider. UpGuard notified iPR on October 24 after detecting the bucket on October 15, and public access was removed on November 26; the exposure underscores risks from misconfigured cloud storage for vendors managing client data.

Misconfigured NICE Systems S3 Exposed Verizon Customer Data

🔒 A misconfigured Amazon S3 repository administered by NICE Systems exposed names, addresses, account details and PINs tied to Verizon customers; UpGuard estimated up to 14 million affected while Verizon disputed a 6 million figure. The publicly accessible bucket contained daily voice-log files and large text archives with unmasked fields such as PIN and CustCode, alongside call analytics metadata. UpGuard notified Verizon in June 2017 and remediation followed, but the incident underscores the severity of third-party cloud misconfigurations and vendor-managed data risk.
