Welcome to Gone Phishing, your daily cybersecurity newsletter that’s your (cybersecurity) Bible, Quran, Torah, Gita, Guru Granth Sahib, and Tripitaka all wrapped into one straight-talking daily newsletter 🤓
Today’s hottest cybersecurity news stories:
📱 iOS, Android users beware of flaws dubbed ‘5Ghoul’ 🎃
💰 Ransomware-as-a-Service (RaaS) is getting worse 💸
👾 GuLoader malware ups its game to avoid detection 🎭
Researchers at Singapore University of Technology and Design unveil "5Ghoul," exposing firmware flaws in 5G modems from major vendors.
🤯 High Risks for 5G Modems 😨🔓
Out of 14 flaws, 10 impact MediaTek and Qualcomm 5G modems, with three classified as high-severity vulnerabilities.
📉 Connection Drops and Downgrades 🚫🔗
Exploiting 5Ghoul allows continuous attacks, connection freezes, and downgrades from 5G to 4G, posing serious risks.
📱 Hundreds of Smartphone Models Affected 📲🌐
714 smartphones from 24 brands, including Vivo, Xiaomi, Apple, and Samsung, are vulnerable to these security flaws.
🛡️ Patches Released ⚙️✨
MediaTek and Qualcomm have released patches for 12 out of 14 flaws, addressing the vulnerabilities promptly.
🕵️♂️ Unrevealed Vulnerabilities 🤐🔍
Details of two remaining vulnerabilities are withheld due to confidentiality, expected to be disclosed in the future.
⚠️ Impact on End-User Security 🕰️📲
Researchers caution that the dependency on vendors can delay patch distribution, affecting end-users' security.
Stay vigilant and update your devices promptly to ensure your 5G security! 🔐📲
Ransomware, especially Ransomware-as-a-Service (RaaS), is transforming the cybersecurity landscape, empowering even those with limited tech skills to launch devastating attacks.
🔄 Traditional vs. Double Extortion Attacks 🛡️
While traditional ransomware encrypts files, modern attackers leverage double extortion, threatening to expose sensitive data, adding complexity and harm to victims.
💼 RaaS Business Model: On-Demand Threats 💻💰
RaaS provides an on-demand model for hackers, offering tools and services for a fee. This model reduces time and costs, making it easier for inexperienced attackers to launch ransomware attacks.
🌐 Marketing Ransomware Tools 📈💻
RaaS fosters economies of scale, with service providers developing new strains and using a customer base to market their tools effectively.
📈 Dark Web Feedback 🌐🗣️
RaaS operates like a competitive market with affiliates giving feedback on the dark web. This competition drives up the quality of services, making it challenging for victims.
🛡️ Defending Against RaaS: Proactive Measures 🛠️🤖
To defend against RaaS, focus on proactive measures, including penetration testing, red teaming, and partnering with a pen testing as a service (PTaaS) provider.
Remember cyber squad, don’t scrimp when it comes to cybersecurity. Even today, may businesses and organisations who fall victim to ransomware attacks end up paying the ransom because it’s the best of two evils 😬 Yikes!

GuLoader, a persistent malware strain, has been unmasked by threat hunters for adopting new tricks, complicating analysis. Elastic Security Labs researcher Daniel Stepanic notes that while the core functionality remains, constant updates in obfuscation techniques make analysis resource-intensive.
📅 Timeline of GuLoader 🕰️🌐
First detected in late 2019, GuLoader, also known as CloudEyE, is an advanced shellcode-based malware downloader. It employs sophisticated anti-analysis techniques and is used to distribute various payloads, including information stealers.
🎣 GuLoader's Preferred Spread 📧🔗
GuLoader typically spreads through phishing campaigns, tricking victims into downloading malware via emails with ZIP archives or links containing Visual Basic Script (VBScript) files.
🔄 GuLoader's Anti-Analysis Improvement 🛠️🕵️♂️
Recent updates include an enhanced anti-analysis technique related to Vectored Exception Handling (VEH), initially disclosed in December 2022. The method involves deliberately disrupting the code execution flow to hinder analysis.
🔄 DarkGate's Evolution 🦠💻
DarkGate, a malware-as-a-service (MaaS) sold by "RastaFarEye," undergoes constant updates. The latest version introduces DLL side-loading and enhanced shellcodes, showcasing its adaptability and evasion methods.
🌐 Modern Malware Sophistication 🌐🛡️
Security researchers emphasise the adaptability, speed of iteration, and depth of evasion methods in modern malware threats, including GuLoader and DarkGate.
📈 Novel Propagation Methods 📧🔄
Remote access trojans like Agent Tesla and AsyncRAT use novel email-based infection chains with steganography and uncommon file types to bypass antivirus detection.
🌐 Evolving Malware Obfuscation Engine 🦠🛠️
The ScrubCrypt malware obfuscation engine, sold on dark web marketplaces, is observed delivering the RedLine stealer malware, showcasing the continuous evolution of cyber threats.
