Why Phishing Is Moving Beyond Email Delivery: Risks

🔗 Phishing attacks are increasingly delivered outside traditional email — via social media, instant messaging, SMS, malvertising and in‑app messengers — making mail gateways insufficient. Attackers now send links from compromised accounts, targeted ads or SaaS messages and use fast‑rotating domains and advanced Attacker‑in‑the‑Middle (AitM) kits that obfuscate JavaScript and the DOM to evade network detection. Organizations often rely on user reports and URL blocking, but these approaches fail against rapid domain churn and client‑side stealth. Vendors such as Push Security propose browser‑level detection that monitors real‑time page behavior to identify AitM, session hijacking and credential theft.

SystemBC Powers REM Proxy, Compromising ~1,500 VPS

🛡️ Lumen Technologies' Black Lotus Labs reports that SystemBC, a C-based SOCKS5 proxy malware, powers roughly 80% of the REM Proxy network and averages about 1,500 compromised hosts per day. The botnet operates through more than 80 C2 servers and mainly targets VPS instances from major commercial providers, often via dropped shell scripts that install the proxy implant. REM Proxy also advertises pools of compromised Mikrotik routers and open proxies and has been used by actors tied to TransferLoader and the Morpheus ransomware group.

SystemBC Turns Compromised VPS into High-Capacity Proxy

🔎 Researchers at Lumen Technology’s Black Lotus Labs say the SystemBC proxy botnet actively targets commercial VPS instances worldwide to build a high-capacity proxy network. The operation averages about 1,500 bots daily, relies on more than 80 C2 servers, and primarily exploits unpatched systems that often contain dozens of vulnerabilities. Customers and operators exhibit poor operational security, and the service is used by ransomware groups and third-party proxy resellers.

SonicWall: Cloud Backup Compromise Impacts 5% of Base

🔒 SonicWall has disclosed a security incident affecting its cloud backup service for firewalls, reporting that threat actors accessed stored preference files for roughly 5% of its install base. While credentials inside those files are encrypted, exposed metadata such as serial numbers could enable future targeting. SonicWall said this was not a ransomware event but a series of brute-force attempts. Impacted customers are asked to check MySonicWall, restrict WAN access, follow the vendor's remediation checklist, and import a supplied preferences file that randomizes local passwords and IPSec keys.

API Attacks Surge: 40,000 Incidents in H1 2025 Report

🔒 Thales' Imperva analysed telemetry from over 4,000 environments and reported about 40,000 API incidents in H1 2025, finding APIs now attract 44% of advanced bot traffic. Key findings included a 40% rise in credential-stuffing and account-takeover attempts against APIs without adaptive MFA, plus data scraping (31%) and coupon/payment fraud (26%). Financial services, telecoms and travel were among the most targeted sectors, and Thales warned the pace and sophistication of attacks will continue to increase.

Browser-Based Attacks: Six Threats Security Teams Must Know

🔒 Browser-targeted attacks are rising as adversaries treat the browser as the primary access point to cloud services and corporate data. The article defines browser-based attacks and enumerates six high-risk techniques: credential and session phishing, ClickFix-style copy-and-paste exploits, malicious OAuth consent flows, rogue extensions, malicious file delivery, and credential reuse where MFA gaps exist. These vectors are effective because modern work happens in decentralized SaaS environments and across many delivery channels, making traditional email- and network-centric defenses less reliable. The piece highlights visibility gaps for security teams and points to vendor platforms such as Push Security that claim to provide in-browser detection and remediation for AiTM phishing, OAuth abuse, and session hijacking.

How Cybercriminals Bypass Logins Using Stolen Credentials

🔐 Cybercriminals increasingly target corporate credentials, authentication tokens and session cookies to bypass MFA and impersonate legitimate users. Stolen credentials accounted for a large share of recent breaches and estimates indicate billions of credentials were exposed in 2024. Organizations can reduce risk with Zero Trust, robust MFA, realistic training and continuous behavioral monitoring to detect suspicious sessions.

VirusTotal Finds 44 Undetected SVG Malware Samples

⚠️ Cybersecurity researchers warn of a phishing campaign using Scalable Vector Graphics (SVG) files that embed JavaScript to decode and inject a Base64-encoded HTML page impersonating Colombia's Fiscalía General de la Nación. VirusTotal identified 44 unique SVG samples that evaded antivirus detection and reported a total of 523 SVGs seen in the wild, with the earliest from August 14, 2025. Attackers relied on obfuscation, polymorphism, and large volumes of junk code to bypass static detections and used a fake progress/download flow to trigger a background ZIP download. The disclosure coincides with separate macOS-focused campaigns distributing the AMOS information stealer via cracked-software lures and Terminal-based installers that attempt to circumvent Gatekeeper protections.

Ukrainian AS FDN3 Linked to Massive Brute-Force Attacks

🔒 Intrinsec reports that Ukraine-based autonomous system FDN3 (AS211736) conducted widespread brute-force and password-spraying campaigns targeting SSL VPN and RDP endpoints between June and July 2025, with activity peaking July 6–8. The firm links FDN3 to two other Ukrainian ASes (AS61432, AS210950) and a Seychelles operator (AS210848) that frequently exchange IPv4 prefixes to evade blocklisting. Intrinsec highlights ties to bulletproof hosting providers and a Russian-associated Alex Host LLC, stressing that offshore peering arrangements complicate attribution and takedown efforts.

Talos Threat Source: Community, Ransomware, and Events

🔗 The latest Threat Source newsletter reflects on the value of the cybersecurity community after Black Hat USA 2025 and DEF CON 33, encouraging practitioners to seek local, affordable alternatives like Bsides, student clubs and hackathons. It summarizes Talos telemetry showing a 1.4× surge in ransomware activity in Japan during H1 2025, with Qilin most active and the new actor Kawa4096 emerging. The edition also highlights major headlines such as an exploited Git vulnerability, updated CISA SBOM guidance, and early reports of an AI-powered ransomware project called PromptLock.

Weak Passwords Fuel Rise in Compromised Accounts in 2025

🔐 The Picus Blue Report 2025 finds that password cracking succeeded in 46% of tested environments, while Valid Accounts (T1078) exploitation achieved a 98% success rate. Many organizations still rely on weak passwords, outdated hashing, and lax internal controls, leaving credential stores exposed. The report urges adoption of widespread MFA, stronger password policies, routine credential-validation simulations, and improved behavioral detection to reduce undetected lateral movement and data theft.

Threat Actor Groups Tracked by Unit 42 — Updated 2025

📌 This Unit 42 reference catalog enumerates selected threat actor groups tracked by Palo Alto Networks, organized by assigned constellation and primary motivation (nation-state, cybercrime, ransomware). It lists aliases, activity summaries, typical sectors impacted and observed TTPs, and highlights recent additions through Aug. 1, 2025. Use of Unit 42 telemetry and the Attribution Framework informs assessments and updates.
