Ransomware is a type of malicious software that encrypts the victim's data, rendering it inaccessible until a ransom is paid. Over the years, ransomware tactics have evolved, becoming more sophisticated and damaging. Originally, ransomware attacks were more indiscriminate, targeting individuals and organizations alike. However, cybercriminals have become more strategic, now focusing on high-value targets.
Ransomware gangs have discovered that targeting CEOs can yield higher returns. By threatening to release sensitive data, they put immense pressure on CEOs to comply with their demands. This method of extortion not only threatens the individual's reputation but also jeopardizes the entire organization's security and financial stability.
Anonymity: Cybercriminals use encryption and the dark web to hide their identities, making it challenging for law enforcement agencies to trace them.
Jurisdictional Challenges: Ransomware attacks are often transnational, complicating legal processes. Different countries have varying laws and levels of cooperation with international authorities.
Sophisticated Techniques: These criminals are adept at covering their tracks, using advanced encryption, and frequently changing their digital footprints to evade detection.
Resource Limitations: Law enforcement agencies often lack the resources and specialized knowledge required to effectively tackle these sophisticated cybercrimes.
The consequences of a ransomware attack can be devastating. For CEOs, the personal and professional stakes are incredibly high. They face potential damage to their reputation, legal ramifications, and significant financial loss. For the organization, it can result in operational disruption, loss of sensitive data, and a breach of trust with customers and stakeholders.
Recent data breaches at Ticketmaster and Santander Bank have exposed major security vulnerabilities in the use of third-party cloud storage services. These breaches highlight the urgent need for robust security measures as more organisations move their data to the cloud.
On May 20, Ticketmaster experienced a data breach involving a third-party cloud storage provider. The breach, disclosed in a regulatory filing by its parent company Live Nation Entertainment, compromised the data of approximately 550 million customers. This stolen data, including sensitive personal information, was reportedly put up for sale on a Dark Web forum by a group known as "ShinyHunters."
Just a week earlier, on May 14, Santander Bank revealed a similar breach. Unauthorised access to a cloud-hosted database exposed data belonging to customers and employees, primarily affecting those in Spain, Chile, and Uruguay. ShinyHunters also claimed responsibility for this breach, offering the stolen data—which includes 30 million customer records, 28 million credit card numbers, and other sensitive information—for sale at $2 million.
Both breaches have been linked to Snowflake, a renowned cloud storage provider serving numerous high-profile clients like MasterCard, Disney, and JetBlue. Although Snowflake acknowledged recent malicious activities targeting its customers, an investigation by Mandiant and CrowdStrike found no evidence of a vulnerability or breach within Snowflake’s own platform. The attackers apparently exploited single-factor authentication credentials obtained through infostealer malware, highlighting the importance of robust authentication measures.
David Bradbury, Chief Security Officer at Okta, stressed the importance of implementing multi factor authentication (MFA) and network IP restrictions for securing SaaS applications. However, he pointed out that attackers are increasingly bypassing MFA by targeting post-authentication processes, such as stealing session tokens. This highlights the need for additional security mechanisms like session token binding.
Michael Lyborg, CISO at Swimlane, emphasised the shared responsibility model in cloud security. While cloud providers like Snowflake offer best practices and security guidelines, it is ultimately up to customers to follow these protocols to protect their data. Lyborg suggested that enforcing MFA and adopting a zero-trust security model by default could enhance data protection by a notable measure.
Challenges in Enforcing Security Standards
Patrick Tiquet, VP of Security and Architecture at Keeper Security, argued that while uniform security measures might enhance protection, they could also limit the flexibility and customization that customers seek from cloud services. He noted that some organizations might have their own robust security protocols tailored to their specific needs. However, the recent breaches at Ticketmaster and Santander highlight the dangers of relying solely on internal security measures without adhering to industry best practices.
The breaches at Ticketmaster and Santander serve as critical reminders of the risks associated with inadequate cloud security measures. As organisations increasingly transition to cloud-based operations, both cloud providers and their customers must prioritise robust security strategies. This includes implementing strong authentication protocols, adhering to best practices, and fostering a culture of security awareness. Ensuring comprehensive protection against cyber threats is essential to safeguarding sensitive data in the digital age.

Check Point Research has been monitoring Sharp Dragon, a Chinese cyber threat group, since 2021. This group, previously known as Sharp Panda, has primarily targeted organisations in Southeast Asia with phishing campaigns. Recently, however, they have expanded their activities to include government organisations in Africa and the Caribbean, marking a significant change in their strategy.
Starting in late 2023, Sharp Dragon shifted its focus to government entities in Africa and the Caribbean. They used previously compromised email accounts from Southeast Asia to send phishing emails. These emails contained documents that appeared legitimate but were actually designed to deliver Cobalt Strike Beacon malware, replacing their earlier use of VictoryDLL and the Soul framework.
The first attack targeting Africa occurred in November 2023, involving a phishing email about industrial relations between Southeast Asia and Africa. By January 2024, further attacks within Africa suggested that some initial attempts had been successful. Similarly, in December 2023, Sharp Dragon targeted a Caribbean government with a document related to a Commonwealth meeting. This was followed by a broader phishing campaign in January 2024, using a fake survey about opioid threats in the Eastern Caribbean.
Sharp Dragon has been refining its tactics. Their new approach includes more thorough checks on target systems before deploying malware. They now use Cobalt Strike Beacon, which allows them to control infected systems without exposing their custom tools immediately. This change helps them avoid detection and gather more information on their targets.
They have also shifted from using DLL-based loaders to executable files disguised as documents. These files write and execute malicious software and create scheduled tasks for persistence on the infected system.
Another major change is Sharp Dragon's use of compromised servers for their command and control operations. Instead of using dedicated servers, they exploit legitimate servers, making their activities harder to detect. For example, in May 2023, they used a vulnerability in the GoAnywhere platform to take over legitimate servers.
Sharp Dragon's new focus on Africa and the Caribbean shows a broader effort by Chinese cyber groups to increase their influence in these regions. After years of targeting Southeast Asia, Sharp Dragon is using its established tactics to gain foothold in new territories. Their refined methods and careful target selection highlight the need for enhanced cybersecurity measures in these regions, which have yet to be as heavily scrutinized by the global cybersecurity community.
A newly identified cyber threat group, known as "Unfading Sea Haze," has been secretly infiltrating military and government networks in the South China Sea region since 2018, according to a recent report by Bitdefender researchers. The group's activities align with Chinese geopolitical interests, focusing on gathering intelligence and conducting espionage. Unfading Sea Haze shares many tactics, techniques, and procedures (TTPs) with other Chinese state-sponsored hacking groups, particularly APT41.
The group's attacks typically begin with spear-phishing emails containing malicious ZIP files disguised as legitimate documents. These ZIP files, often named to appear as Windows Defender installers, contain LNK files with obfuscated PowerShell commands. If an ESET security executable is detected on the target system, the attack is halted. Otherwise, the PowerShell script uses Microsoft's msbuild.exe to launch fileless malware directly into memory, leaving no traces on the victim's machine.
The code executed by MSBuild installs a backdoor called 'SerialPktdoor,' which gives the attackers remote control over the compromised system. Additionally, the hackers use scheduled tasks and manipulate local administrator accounts to maintain their presence on the network. By resetting and enabling the typically disabled local admin account, they create a hidden profile for continuous access.
Unfading Sea Haze employs a variety of custom tools and malware. Among these are 'xkeylog,' a keylogger for capturing keystrokes, info-stealers targeting browser data, and PowerShell scripts for extracting information. Since 2023, the group has adopted stealthier methods, such as abusing msbuild.exe to load C# payloads from remote SMB shares and deploying different variants of the Gh0stRAT malware.
Bitdefender has identified several Gh0stRAT variants used by the hackers:
1. SilentGh0st: A variant with extensive functionality through numerous commands and modules.
2. InsidiousGh0st: A Go-based evolution with enhanced capabilities, including TCP proxy, SOCKS5, and improved PowerShell integration.
3. TranslucentGh0st, EtherealGh0st, and FluffyGh0st: Newer variants designed for evasive operations with dynamic plugin loading and a lighter footprint.
Earlier attacks utilised tools like Ps2dllLoader for loading .NET or PowerShell code into memory and SharpJSHandler, a web shell for executing encoded JavaScript via HTTP requests. The group also created a tool to monitor newly connected USB and Windows Portable Devices every ten seconds, reporting device details and specific files to the attackers.
For data exfiltration, Unfading Sea Haze initially used a custom tool named 'DustyExfilTool,' which securely extracted data via TLS over TCP. In more recent attacks, the group has shifted to using a curl utility and the FTP protocol, with dynamically generated credentials that are frequently changed to enhance security.
The sophisticated techniques employed by Unfading Sea Haze highlight the need for robust cybersecurity defences. Organisations should implement a comprehensive security strategy that includes regular patch management, multi-factor authentication (MFA), network segmentation, traffic monitoring, and advanced detection and response tools.
By adopting these measures, organisations can better defend against the persistent and evolving threats posed by groups like Unfading Sea Haze. The group's ability to remain undetected for six years sets a strong precedent for the critical importance of vigilance and continuous improvement in cybersecurity practices.
