#FactCheck - Viral Video Falsely Linked to Netanyahu’s Brother’s Death, Old Funeral Clip Misused

Introduction

The ramifications of cybercrime can be far-reaching. Depending on the size of the attack, even entire countries can be affected if their critical infrastructure is connected to the internet. The vast majority of security breaches start within the perimeter and most internet attacks are socially engineered. Unwittingly trusting any email or web request from an unknown sender creates a potential danger for those organisations that depend on the Internet for their business functions. In this ever-evolving digital downtown yet another group has emerged from its darkest corners of targeting the UK’s very bastion of British and global heritage; a treasure trove of around 14 million volumes, ancient manuscripts, in the precious British Library. A group self-identified as Rhysida. Their bold maneuver, executed with the stealth of seasoned cyber brigands, has cast a shadow as long and dark as those found in the Gothic novels that rest on the library's shelves. The late October cyber-attack has thrust the British Library into an unnerving state of chaos, a situation more commonly aligned with works of dystopian fiction than the everyday reality of a revered institution.

The Modus Operandi

The gang uses all-new Rhysida ransomware to jeopardize Virtual Private Networks, which is typically used by library staff to gain access to their employee’s systems remotely. The Ransomware presents itself as a regular decoy file in a familiar fashion as regular phishing attacks in an email, tricking its victim and downloading itself into the host system.  Once the malware enters the system it stays dormant and lurks around the system for a period of time. The new malware has significantly reduced the dwell time from 4 days to less than 24 hours which enables it to evade periodic system checks to avoid detection.

 Implications of Cyber Attack

Implications of the cyber-attack have been sobering and multifaceted. The library's systems, which serve as the lifeline for countless scholars, students, and the reading public, were left in disarray, unsettlingly reminiscent of a grand mansion invaded by incorporeal thieves. The violation has reverberated through the digital corridors of this once-impenetrable fortress, and the virtual aftershocks are ongoing. Patrons, who traverse a diverse spectrum of society, but share a common reverence for knowledge, received unsettling news: the possibility that their private data has been compromised—a sanctity breached, revealing yet again how even the most hallowed of spaces are not impervious to modern threats.

It is with no small sense of irony that we consider the nature of the stolen goods—names, email addresses, and the like. It is not the physical tomes of inestimable value that have been ransacked, but rather the digital footprints of those who sought the wisdom within the library's walls. This virtual Pandora's Box, now unleashed onto the dark web, has been tagged with a monetary value. Rhysida has set the ominous asking price of a staggering $740,000 worth of cryptocurrency for the compromised data, flaunting their theft with a hubris that chills the spine.

Yet, in this convoluted narrative unfolds a subplot that offers some measure of consolation. Payment information purports the library has not been included in this digital heist, offering a glint of reassurance amidst the prevailing uncertainty. This digital storm has had seismic repercussions: the library's website and interconnected systems have been besieged and access to the vast resources significantly hampered. The distressing notice of a 'major technology outage' transformed the digital facade from a portal for endless learning to a bulletin of sorrow, projecting the sombre message across virtual space.

The Impact

The impact of this violation will resonate far beyond the mere disruption of services; it signals the dawn of an era where venerable institutions of culture and learning must navigate the depths of cybersecurity. As the library grapples with the breach, a new front has opened in the age-old battle for the preservation of knowledge. The continuity of such an institution in a digitised world will be tested, and the outcome will define the future of digital heritage management. As the institution rallies, led by Roly Keating, its Chief Executive, one observes not a defeatist retreat, but a stoic, strategic regrouping. Gratitude is extended to patrons and partners whose patience has become as vital a resource as the knowledge the library preserves. The reassurances given, while acknowledging the laborious task ahead, signal not just an intention to repair but to fortify, to adapt, to evolve amidst adversity.

This wretched turn of events serves as a portentous reminder that threats to our most sacred spaces have transformed. The digital revolution has indeed democratised knowledge but has also exposed it to neoteric threats. The British Library, a repository of the past, must now confront a distinctly modern adversary. It requires us to posit whether our contemporary guardians of history are equipped to combat those who wield malicious code as their weapons of choice.

Best Practices for Cyber Resilience 

It is crucial to keep abreast with recent developments in cyberspace and emerging trends. Libraries in the digital age must ensure the protection of their patron’s data by applying comprehensive security protocols to safeguard the integrity, availability and confidentiality of sensitive information of their patrons. A few measures that can be applied by libraries include. 

• Secured Wi-Fi networks: Libraries offering public Wi-Fi facilities must secure them with strong encryption protocols such as WPA 3. Libraries should establish separate networks for internal operations allowing separation of staff and public networks to protect sensitive information. 
• Staff Training Programs: To avoid human error it is imperative that comprehensive training programs are conducted on a regular basis to generate greater awareness of cyber threats among staff and educate them about best practices of cyber hygiene and data security. 
• Data Backups and Recovery Protocols: Patrons' sensitive data should be updated and backed up regularly. Proper verification of the user’s data integrity is crucial and should be stored securely in a dedicated repository to ensure full recovery of the user’s data in the event of a breach. 
• Strong Authentication: Strong authentication to enhance library defenses is crucial to combat cyber threats. Staff and Patrons should be educated on strong password usage and the implementation of Multi-Factor Authentication to add an extra layer of security. 

Conclusion

Finally, whatever the future holds, what remains unassailable is the cultural edifice that is the British Library. Its trials and tribulations, like those of the volumes it safeguards, become a part of a larger narrative of endurance and defiance. In the canon of history—filled with conflicts and resolutions—the library, like the lighter anecdotes and tragic tales it harbours, will decidedly hold its place. And perhaps, with some assurance, we might glean from the sentiment voiced by Milton—an assurance that the path from turmoil to enlightenment, though fraught with strenuous challenges, is paved with lessons learned and resilience rediscovered. Cyberspace is constantly evolving hence it is in our best interest to keep abreast of all developments in this digital sphere. Maximum threats can be avoided if we are vigilant.

Introduction

The increased use of zero-day vulnerabilities by more complex threat actors reinforces the importance of more developed countermeasures. One of the threat actors identified is BrazenBamboo uses a zero-day vulnerability in Fortinet FortiClient for Windows through the DEEPDATA advanced malware framework. This research explores technical details about DEEPDATA, the tricks used in its operations, and its other effects.

Technical Findings

1. Vulnerability Exploitation Mechanism

The vulnerability in Fortinet’s FortiClient lies in its failure to securely handle sensitive information in memory. DEEPDATA capitalises on this flaw via a specialised plugin, which:

• Accesses the VPN client’s process memory.
• Extracts unencrypted VPN credentials from memory, bypassing typical security protections.
• Transfers credentials to a remote C2 server via encrypted communication channels.

2. Modular Architecture

DEEPDATA exhibits a highly modular design, with its core components comprising:

• Loader Module (data.dll): Decrypts and executes other payloads.
• Orchestrator Module (frame.dll): Manages the execution of multiple plugins.
• FortiClient Plugin: Specifically designed to target Fortinet’s VPN client.

Each plugin operates independently, allowing flexibility in attack strategies depending on the target system.

3. Command-and-Control (C2) Communication

DEEPDATA establishes secure channels to its C2 infrastructure using WebSocket and HTTPS protocols, enabling stealthy exfiltration of harvested data. Technical analysis of network traffic revealed:

• Dynamic IP switching for C2 servers to evade detection.
• Use of Domain Fronting, hiding C2 communication within legitimate HTTPS traffic.
• Time-based communication intervals to minimise anomalies in network behavior.

4. Advanced Credential Harvesting Techniques

Beyond VPN credentials, DEEPDATA is capable of:

• Dumping password stores from popular browsers, such as Chrome, Firefox, and Edge.
• Extracting application-level credentials from messaging apps like WhatsApp, Telegram, and Skype.
• Intercepting credentials stored in local databases used by apps like KeePass and Microsoft Outlook.

5. Persistence Mechanisms

To maintain long-term access, DEEPDATA employs sophisticated persistence techniques:

• Registry-based persistence: Modifies Windows registry keys to reload itself upon system reboot.
• DLL Hijacking: Substitutes legitimate DLLs with malicious ones to execute during normal application operations.
• Scheduled Tasks and Services: Configures scheduled tasks to periodically execute the malware, ensuring continuous operation even if detected and partially removed.

Additional Tools in BrazenBamboo’s Arsenal

1. DEEPPOST

A complementary tool used for data exfiltration, DEEPPOST facilitates the transfer of sensitive files, including system logs, captured credentials, and recorded user activities, to remote endpoints.

2. LightSpy Variants

• The Windows variant includes a lightweight installer that downloads orchestrators and plugins, expanding espionage capabilities across platforms.
• Shellcode-based execution ensures that LightSpy’s payload operates entirely in memory, minimising artifacts on the disk.

3. Cross-Platform Overlaps

BrazenBamboo’s shared codebase across DEEPDATA, DEEPPOST, and LightSpy points to a centralised development effort, possibly linked to a Digital Quartermaster framework. This shared ecosystem enhances their ability to operate efficiently across macOS, iOS, and Windows systems.

Notable Attack Techniques

1. Memory Injection and Data Extraction

Using Reflective DLL Injection, DEEPDATA injects itself into legitimate processes, avoiding detection by traditional antivirus solutions.

• Memory Scraping: Captures credentials and sensitive information in real-time.
• Volatile Data Extraction: Extracts transient data that only exists in memory during specific application states.

2. Fileless Malware Techniques

DEEPDATA leverages fileless infection methods, where its payload operates exclusively in memory, leaving minimal traces on the system. This complicates post-incident forensic investigations.

3. Network Layer Evasion

By utilising encrypted DNS queries and certificate pinning, DEEPDATA ensures that network-level defenses like intrusion detection systems (IDS) and firewalls are ineffective in blocking its communications.

Recommendations

1. For Organisations

• Apply Network Segmentation: Isolate VPN servers from critical assets.
• Enhance Monitoring Tools: Deploy behavioral analysis tools that detect anomalous processes and memory scraping activities.
• Regularly Update and Patch Software: Although Fortinet has yet to patch this vulnerability, organisations must remain vigilant and apply fixes as soon as they are released.

2. For Security Teams

• Harden Endpoint Protections: Implement tools like Memory Integrity Protection to prevent unauthorised memory access.
• Use Network Sandboxing: Monitor and analyse outgoing network traffic for unusual behaviors.
• Threat Hunting: Proactively search for indicators of compromise (IOCs) such as unauthorised DLLs (data.dll, frame.dll) or C2 communications over non-standard intervals.

3. For Vendors

• Implement Security by Design: Adopt advanced memory protection mechanisms to prevent credential leakage.
• Bug Bounty Programs: Encourage researchers to report vulnerabilities, accelerating patch development.

Conclusion

DEEPDATA is a form of cyber espionage and represents the next generation of tools that are more advanced and tunned for stealth, modularity and persistence. While Brazen Bamboo is in the process of fine-tuning its strategies, the organisations and vendors have to be more careful and be ready to respond to these tricks. The continuous updating, the ability to detect the threats and a proper plan on how to deal with incidents are crucial in combating the attacks.

"Cybercriminals are unleashing a surprisingly high volume of new threats in this short period of time to take advantage of inadvertent security gaps as organizations are in a rush to ensure business continuity.”

Cyber security firm Fortinet on Monday announced that over the past several weeks, it has been monitoring a significant spike in COVID-19 related threats.

An unprecedented number of unprotected users and devices are now online with one or two people in every home connecting remotely to work through the internet. Simultaneously there are children at home engaged in remote learning and the entire family is engaged in multi-player games, chatting with friends as well as streaming music and video. The cybersec firm’s FortiGuard Labs is observing this perfect storm of opportunity being exploited by cybercriminals as the Threat Report on the Pandemic highlights:

A surge in Phishing Attacks: The research shows an average of about 600 new phishing campaigns every day. The content is designed to either prey on the fears and concerns of individuals or pretend to provide essential information on the current pandemic. The phishing attacks range from scams related to helping individuals deposit their stimulus for Covid-19 tests, to providing access to Chloroquine and other medicines or medical device, to providing helpdesk support for new teleworkers.

Phishing Scams Are Just the Start: While the attacks start with a phishing attack, their end goal is to steal personal information or even target businesses through teleworkers. Majority of the phishing attacks contain malicious payloads – including ransomware, viruses, remote access trojans (RATs) designed to provide criminals with remote access to endpoint systems, and even RDP (remote desktop protocol) exploits.

A Sudden Spike in Viruses: The first quarter of 2020 has documented a 17% increase in viruses for January, a 52% increase for February and an alarming 131% increase for March compared to the same period in 2019. The significant rise in viruses is mainly attributed to malicious phishing attachments. Multiple sites that are illegally streaming movies that were still in theatres secretly infect malware to anyone who logs on. Free game, free movie, and the attacker is on your network.

Risks for IoT Devices magnify: As users are all connected to the home network, attackers have multiple avenues of attack that can be exploited targeting devices including computers, tablets, gaming and entertainment systems and even online IoT devices such as digital cameras, smart appliances – with the ultimate goal of finding a way back into a corporate network and its valuable digital resources.

Ransomware like attack to disrupt business: If the device of a remote worker can be compromised, it can become a conduit back into the organization’s core network, enabling the spread of malware to other remote workers. The resulting business disruption can be just as effective as ransomware targeting internal network systems for taking a business offline. Since helpdesks are now remote, devices infected with ransomware or a virus can incapacitate workers for days while devices are mailed in for reimaging.

“Though organizations have completed the initial phase of transitioning their entire workforce to remote telework and employees are becoming increasingly comfortable with their new reality, CISOs continue to face new challenges presented by maintaining a secure teleworker business model. From redefining their security baseline, or supporting technology enablement for remote workers, to developing detailed policies for employees to have access to data, organizations must be nimble and adapt quickly to overcome these new problems that are arising”, said Derek Manky, Chief, Security Insights & Global Threat Alliances at Fortinet – Office of CISO.
