π¨ New phishing campaign exploits Cisco domains to bypass security filters
The threat intelligence team at Outpost24 just documented a sophisticated attack that shows how attackers are taking phishing to the next level.
How does it work?
π§ It starts with an email impersonating JP Morgan, inserted into what looks like an existing thread. The email passes DMARC thanks to legitimate DKIM signatures via Amazon SES.
π The "Review Document" link points to https://t.co/v9BivuXshi β a trusted domain no one would block.
π From there, the victim bounces through Nylas (a legitimate email API platform), then through a compromised server in India, next through a domain originally registered in 2017 with residual reputation, and finally lands on the real phishing page protected by Cloudflare.
π‘οΈ 6 hops through trusted infrastructure. Each link in the chain has good reputation on its own. Traditional filters don't evaluate the full chain.
π‘ Key takeaways:
β’ A known domain in the URL doesn't guarantee safety
β’ Valid DKIM signatures don't mean the sender is legitimate
β’ Phishing-resistant MFA (FIDO2/WebAuthn) is no longer optional
β’ Ongoing security awareness training remains the first line of defense
The good news: the attack was detected and unsuccessful. β
The bad news: these techniques will keep evolving. π

Artificial intelligence is no longer slowly entering our professions β
it is beginning to redefine them in real time βοΈ
First it impacted visual creativity π¨, then writing βοΈ, then programming π»β¦ and now it is starting to directly influence cybersecurity π and technical decision-making.
Every new technological release does not only introduce a tool β it changes the very way work is understood.
That is why we see immediate reactions in the stock market π not because companies suddenly lose value overnight, but because the market anticipates a shift in the production model.
When the way knowledge is produced changes, the way value is produced changes as well.
However, these movements do not mean the end of professions β they mean transformation π
Technology has always followed the same pattern: tasks disappear, but more complex roles emerge.
Artificial intelligence automates execution π€
but increases the need for human judgment π§
Therefore, the right approach is not fear, but adaptation π
Stay calm, keep studying, understand the new tools, and learn how to work with them instead of resisting them π
π¨ Notepad++ Supply Chain Attack β Advanced Technical Summary
Recent investigations revealed a highly sophisticated supply chain compromise impacting Notepad++ update infrastructure, enabling attackers to selectively deliver trojanized installers to targeted victims.
According to Kaspersky GReATβs deep technical analysis, this was not a single-stage incident, but a long-running, multi-phase campaign active between June and December 2025.
Key technical insights from Kaspersky:
𧬠Multiple infection chains
- At least three distinct execution chains were identified
- Each chain used different:
β οΈ C2 servers
β οΈ Domains
β οΈ File hashes
β οΈ Payloads
- Tooling and infrastructure were rotated roughly monthly to evade detection
π― Highly targeted operation
- Victims included:
π΄ Government organizations (Philippines)
π΄ Financial institutions (El Salvador)
π΄ IT service providers (Vietnam)
π΄ Individuals across multiple regions
- The campaign was selective, not mass-distributed
π οΈ Advanced malware tradecraft
Delivery of the Chrysalis backdoor/loader
- Use of NSIS-based malicious installers
- Abuse of legitimate updater process (GUP.exe)
- DLL sideloading to load malicious payloads
- Use of Cobalt Strike Beacons
- Metasploit-based payload delivery
- Frequent infrastructure rotation to bypass IOC-based detection
ποΈ Key TTPs observed
- Registry Run Key persistence
- Collection and exfiltration of:
π οΈ Process lists
π οΈ System information
π οΈ Network connections
- Use of temporary file hosting (e.g., temp[.]sh)
- Multiple previously undisclosed IoCs published by Kaspersky
β οΈ Critical defensive takeaway
- A clean scan against public IoCs does not guarantee historical non-compromise
- Earlier infection chains used completely different indicators
- This highlights the limits of static IOC-based detection for APT-level supply chain attacks
This incident reinforces that modern supply chain attacks are:
π΄ Targeted
π΄ Long-lived
π΄ Multi-stage
π΄ Designed to evade traditional detection

π¨ Cybersecurity Alert: Radiant Ransomware Group Shuts Down and Offers Free Decryption for Hospitals & Schools π
The Radiant ransomware group has issued a surprising statement announcing their full shutdown of operations and withdrawal from the dark web. This decision appears to be a direct response to the intense public condemnation generated by their attacks.
Most notably, they are attempting to "compensate" by focusing exclusively on the Health and Education sectors:
β’ Specific Offer: Radiant is providing a complete free decryptor for any Hospital π₯ or School π« that was victimized by them.
β’ Motivation: The group states that attacks on hospitals and children are "unpleasant targets" and apologizes for the damage caused.
π‘ Key Implications
1.- Reputational Impact: The Radiant case underscores how public opinion and media condemnation can influence cybercrime groups.
2.- Lingering Risk: Despite the shutdown, data stolen from non-paying victims has reportedly been sold to third parties. The risk of a data leak still persists.
π Call to Action for Victims (Hospitals/Schools)
If your Hospital or Educational Center was affected by a recent ransomware attack, it is crucial to make contact as soon as possible to try and obtain the free decryptor.
Free Decryption Contact (ONLY Hospitals/Schools): 97DF90F5B408E053465D6A3F85596DB3B2342CA47D1D944D45A0A6E654A5A33CF9D634B13981
π Transition of Weyhro Group: From Ransomware Operators to Offensive Cyber-Mercenary Services
π΅οΏ½οΏ½οΏ½ββοΈ Intelligence gathered from cybercrime underground forums indicates a strategic pivot by the threat actor known as "Weyhro." Formerly identified exclusively as a ransomware operator targeting corporate entities, the group has transitioned into a "Cyber-Mercenary" and infrastructure provider role.
π The actor's timeline shows active ransomware operations from December 12, 2024, to August 10, 2025. Following a period of silence, the actor resurfaced on December 3, 2025, not to recruit affiliates for a RaaS scheme, but to sell a proprietary C2 framework and offer direct offensive services to other criminals.
π― Strategic Objectives
β’ πΌ Professionalization of Cybercrime: Move away from typical affiliate models to offer specialized, tiered "consulting" services (Pentesting, Intelligence, Extortion) with fixed pricing or profit-sharing models.
β’ π° Tool Monetization: Capitalize on internal development by licensing the "Weyhro C2" framework, likely battle-tested during their previous ransomware campaigns.
β’ π» Operational Evasion: Maintain a focus on stealth and anti-forensics to ensure the longevity of their tools and services in controlled corporate environments.
π οΈ Attack Tools & Methods
Weyhro C2 Framework:A modular Command and Control agent designed for stealth and persistence, offered at π΅ a significant monthly subscription. It strictly prohibits execution on CIS (Commonwealth of Independent States) machines π«π·πΊ.
Communication & Access:
π Shell: High-speed interactive reverse shell for real-time command execution β‘.
π SOCKS5: Stable resident proxy compatible with ProxyChains for lateral movement within internal networks π.
π» HVNC (Hidden VNC): Launches a covert browser session utilizing the victim's profile data (πͺ cookies, π passwords) for undetectable remote access π΅οΈββοΈ.
Credential Theft:
ποΈ Kerberos Dumper: Automates the extraction of Kerberos tickets (current or all sessions via admin) and LSASS dumps π.
Advanced Evasion:
π‘οΈ Defense Evasion: Features polymorphic code π§¬, compression π¦, AES/ChaCha20 encryption π, API Unhooking, and AMSI/ETW bypass to evade EDR detection π«ποΈ.
π Operational Services & Business Model
The group now operates a structured service menu, allowing third parties to outsource specific stages of an attack chain. The pricing reflects the level of effort and risk assumed by Weyhro:
βοΈ Pentest (Significant fixed sum):
Scope: Hacking into systems and obtaining administrative rights π.
Requirements: Just access to the target π―.
π§ Intelligence (Standard fixed sum):
Scope: OSINT gathering of company contact data (π§ emails, π± phones) and forcing communication channels π£.
Requirements: Company name or website π.
π’ Extortion (30/70 Profit Split):
Scope: Coercing companies to pay to prevent data leaks π§.
Requirements: Corporate data and ZoomInfo access π.
Split: Weyhro retains 30%, client keeps 70% π.
π₯ Compromise (70/30 Profit Split):
Scope: Full-spectrum attack execution: Pentest, data theft, system destruction π£, followed by extortion.
Requirements: Just access to the target π―.
Split: Weyhro retains 70%, client keeps 30% (reflecting the heavy operational load on Weyhro) π.
π Impact & Hypothesis
β’ ποΈ Internal Capability to Commercial Product: The release of Weyhro C2 and the specific "Compromise" service strongly suggests that the group is monetizing the exact TTPs (Tactics, Techniques, and Procedures) used during their 2024-2025 ransomware campaign. The "Compromise" service essentially allows unskilled actors to pay Weyhro to conduct a full ransomware-style attack on their behalf π€.
β’ πΊοΈ Attribution & Origin: The strict "No-CIS" restriction on the C2 tool reaffirms the likelihood of the operators being based in Russia or Eastern Europe. The naming convention remains ambiguous; it is unclear if "Weyhro" was initially a project name that became the group's alias, or vice versa, but the brand is now being leveraged to sell high-end cybercriminal services π΄ββ οΈ.
@RussianPanda9xx It appears that the Weyhro group, which was initially focused on ransomware, has expanded its "business scope." They now provide a "service" kit, and I estimate that this shift has motivated them to develop a tool both for their own use and for rental to third parties π οΈπ»π΅οΈββοΈ
Hi friends! ππ
Iβve been MIA for 7 months because I was fully focused on an academic project Iβm really excited aboutβ¦ I just finished my first scientific paper! ππ
Itβs been an intense journey of math, strange patterns, and a lot of code while diving deeper into cryptography.
Iβm now checking if my universityβs scientific journal is the right place to publish it, so the title and details stay secret for now π€«.
Iβm officially back! Thanks for sticking around. β¨

Headline: π¨ Major Data Privacy Enforcement in China: 70 Mobile Apps Cited for Violations.
China's National Computer Virus Emergency Response Center (CVERC) has officially notified 70 mobile applications for illegal and improper collection and use of personal information.
This detection effort, conducted between September 1 and September 28, 2025, is part of a broader high-level "2025 Personal Information Protection Special Action" involving multiple state ministries (CAC, MIIT, MPS, SAMR) aimed at enforcing the Cybersecurity Law and the Personal Information Protection Law (PIPL).
π Key Insights & Major Violations Detected:
The report identifies 12 distinct categories of compliance failures across the 70 apps. The most significant issues include:
π‘οΈ Critical Security Gaps: The largest category (34 apps) failed to implement necessary security measures like encryption or de-identification of data.
π Privacy Policy Failures: Many apps had inadequate policies that didn't clearly state the scope of collection, were difficult to access, or failed to prompt users approriately upon first launch.
π Consent Issues: Significant hurdles for users trying to withdraw consent, or apps collecting data before obtaining consent.
π Unauthorized Sharing: Sharing data with third parties (via SDKs/plugins) without separate consent or anonymization.
πΆ Minors' Data at Risk: Several apps mishandled the data of minors under 14, lacking specific rules or guardian consent.
π« No Policy at All: 9 apps were found operating with absolutely no privacy policy.
π Enforcement Outcome: Besides listing the current 70 offenders, CVERC noted that 28 apps identified in a previous report failed to rectify issues upon re-testing and have been removed from app distribution platforms.
