🔍 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.

🔍 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. Delivery begins with SEO-poisoning archives containing a downloader that writes a polling PowerShell script to C:\ProgramData and executes received code with Invoke-Expression.

💰 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.

🔒 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.

📰 The HBO Max documentary Most Wanted: Teen Hacker features interviews with Brian Krebs and examines the criminal trajectory of Julius Kivimäki, a Finnish hacker convicted for extensive data breaches and later mass extortion. The four-part series traces his early role in the Lizard Squad, high-profile DDoS attacks, swatting incidents, and the Vastaamo psychotherapy breach and patient extortion. Directed by Sami Kieski and co-written by Joni Soila, episodes will stream weekly on Fridays throughout September.

🛡️ 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.

⚠ 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'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.

🔍 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.

📄 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.

🔍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.

🔍 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.

🔒 The UpGuard Cyber Risk Team discovered an unsecured AggregateIQ (AIQ) code repository containing site backups, API keys, SSL private keys, and other sensitive assets tied to multiple Canadian campaigns and parties. Exposed files included WordPress backups, donation processor keys (Stripe), NationBuilder tokens, and PEM private keys that could enable impersonation or account takeover. The findings illustrate significant third‑party vendor risk and raise regulatory and public‑interest concerns about how AggregateIQ managed client credentials and campaign tooling.

🔐 The UpGuard Cyber Risk Team discovered exposed repositories belonging to AggregateIQ that contained website code, backups, credentials and tokens associated with multiple Canadian political campaigns and parties. Exposed artifacts included Stripe secret keys, private SSL keys, NationBuilder/Helcim/SendGrid tokens, WordPress database credentials, and admin accounts tied to aggregateiq.com. The incident highlights third-party vendor risk and the need for tighter controls on credentials and repository configurations.

🔍 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.

🔓 On October 3, 2017 UpGuard researcher Chris Vickery discovered a publicly accessible Amazon S3 bucket belonging to National Credit Federation containing 111 GB of internal and customer records. The repository included scanned IDs, Social Security card images, full credit reports from Equifax, Experian, and TransUnion, personalized credit blueprints, and full bank and card numbers. National Credit Federation secured the bucket after notification and UpGuard found no evidence of theft in this report. The case underscores the necessity of validating cloud storage permissions and continuously monitoring third-party risk.

🔎 UpGuard discovered an unauthenticated Elasticsearch index containing roughly 22 million web-request records, of which about 95% referenced leakzone.net. The logs included client IP addresses, destination domains, request sizes, geolocation data and ISP metadata, spanning June 25 to discovery on July 18, with about one million requests per day. Analysis found extensive use of public proxies and clustered VPN exit nodes, alongside many one-off IPs likely representing direct users. The dataset raises privacy and operational concerns for visitors, service operators, and investigators.

🔓 UpGuard Research discovered a publicly accessible Amazon S3 bucket containing detailed consumer data attributed to Tetrad, including files derived from Experian Mosaic, Claritas/PRIZM, and client-supplied datasets covering over 120 million U.S. household records. The exposure included full names, addresses, gender, Mosaic codes, and retailer account and purchase information. UpGuard notified Tetrad in early February and, after repeated contact, the company removed public access and secured the bucket. The dataset's breadth raises significant privacy and targeted-risk concerns for individuals and communities.
