Over the past few years, the uncomfortable truth in the cybersecurity industry has become clear: security devices designed to protect customers from hackers and cybercriminals are often considered an easy target for these very threats. Vulnerabilities in devices such as firewalls and virtual private network (VPN) devices have been repeatedly exploited, allowing trained attackers to enter systems that were supposed to be secure. In this context, a recent report from the British cybersecurity firm “Sophos” reveals a battle that has lasted more than five years against a group of hackers targeting its products. The report uncovers exciting details about how “Sophos” has tracked these attacks, including the use of advanced techniques to monitor attackers’ activities and dismantle their methods of exploiting vulnerabilities. We will delve into the details of this intriguing conflict and discuss the lessons learned that shed light on some of the significant challenges facing the cybersecurity industry today.
Challenges Facing Cybersecurity Devices
Despite significant advancements in cybersecurity technology, there remains a lack of trust between security devices and users who are fighting against the increasing threats from hackers and cybercriminals. In recent years, a range of vulnerabilities has been uncovered in protective devices such as firewalls and VPNs, which were supposed to provide reliable protection to customers. These vulnerabilities are often used by attackers as entry points to access the systems that are supposed to be protected.
These challenges are clearly illustrated through the experiences of companies like Sophos, which has specifically monitored hacker attacks from China targeting its products actively over more than five years. This ongoing war between Sophos and these attackers underscores the difficulty of mitigating risks for companies even with advanced security measures in place. For example, the discovery of flaws in Sophos systems indicated a deep level of threats, making it an opportunity to monitor the evolution of these threats and study the methods hackers use to gather information.
The Technology Used in the Sophos Breaches
Sophos faced multiple breaches that began in 2018. At that time, the company discovered malware on a computer in its office in India, which raised their alarm due to the unusual activities exhibited by this malicious software. However, what followed was more complex; Sophos discovered that hackers had breached multiple devices on the network. Through investigation, analyses showed that the attack aimed to gather information about Sophos products to facilitate future attacks on its customers. This was followed by a series of attacks that used sophisticated malware such as Asnarök, which operates to create botnets for subsequent attack purposes.
As the attacks progressed, Sophos began to establish a special team tasked with tracking and resolving these attacks. They embarked on this challenge by expanding their knowledge of the abnormal activities of the attackers. By monitoring the devices used by the hackers and their locations, Sophos was able to identify different patterns of exploitation.
Sophos’s Strategies in Facing Threats
Sophos is developing advanced strategies to counter these threats. One of the most notable of these strategies involved equipping its devices with new tools and applications to gather information about abnormal activities. This measure enabled them to analyze and anticipate attacks, which also helped them provide their customers with quicker solutions to counter breaches before they escalated.
For example, Sophos used techniques to monitor researchers and hackers in a well-known research network in Chengdu, China, where a group of researchers was tracked that possessed the methods and information required to exploit vulnerabilities in security products. The team at Sophos worked openly to analyze malicious code and discover methods for manipulating their software, which enabled them to thwart some attacks before they were executed directly. This proactive approach yielded valuable information from malicious actors, allowing the company to redesign its systems in a stronger and more secure manner.
Developments
The Latest in the Security Environment
The cybersecurity environment has witnessed rapid developments in recent years, and with the multitude of threats and the emergence of new technologies, it has become essential for companies like Sophos to adapt and change. For instance, a wide range of attacks targeting critical infrastructure has been identified around the world, such as campaigns aimed at government agencies and energy service facilities.
Studies show that most of these attacks were carried out using advanced techniques and through the collaboration of hacker groups receiving support from certain governments. Institutions using Sophos products need to be more aware of threats and collaborate with the company to collectively address the challenges. The daily interactions between Sophos and hackers will not end, but through continuous innovation and partnerships among companies, security solutions can evolve to effectively reduce risks.
Developments in Cyber Attacks
Recent years have seen a significant rise in cross-border cyber activities, with cyber attacks becoming increasingly targeted against specific countries and individuals. Among these activities are the attacks targeting Tibetan exiles, reflecting the strategic thinking of certain nations, such as China. Mucaire, an official at Sophos, notes the emergence of numerous activities directed against their security systems, indicating the rise of what can be called a “Pandora’s box” of information regarding threats. This phenomenon underscores the need to enhance security approaches and countermeasures to address the growing threats.
The threats have escalated significantly, with the evolution of hacking tools being a core part of this dynamic. Attacking groups have utilized new techniques, including “bootkit” malware designed to penetrate the low-level code of firewall equipment, making detection difficult. Such tools indicate that hackers are going beyond merely finding new vulnerabilities and are seeking complex methods to infiltrate systems.
Sophos’s Struggle with the Chengdu Hacker Group
Sophos faces a complex challenge from a hacker group focusing its efforts in the Chinese city of Chengdu, reflecting the dissonance of attacks with state objectives and the limits of cybersecurity. Statements suggest an ambiguous relationship between security researchers finding vulnerabilities and attackers exploiting these vulnerabilities to meet state demands. Sometimes, some of these researchers have come to offer their vulnerabilities to Sophos itself through its bug bounty program, reflecting the interconnectedness between security research and governmental objectives.
This phenomenon reflects the reality of a culture promoting national loyalty among cybersecurity researchers in China, but unfortunately, these individuals do not hesitate to seek additional financial returns. Mucaire warns that these interactions lead to a greater problem which poses a risk to global cybersecurity. This calls for a verification of goals and priorities and demands a rethinking of how vulnerabilities are managed in a context characterized by secrecy and lack of transparency.
Challenges of Unsupported Devices
Sophos’s report points to a shift in attack strategies towards targeting outdated devices that no longer receive updates, reflecting a real danger to cybersecurity. The report highlights how these devices, often left unmaintained, represent easy entry points for hackers. The company’s director, Joe Levy, states that the current threat lies not only in new vulnerabilities but in “vulnerabilities that have been around for 365 days” or even older, as the digital environment encompasses a large number of devices that have become neglected.
This phenomenon threatens not only private institutions but also national infrastructure. As reliance on legacy systems increases due to cost or ease of use, the risks associated with ignoring updates become greater. Experts like Jeff Green, the assistant director of the cybersecurity office, indicate that these perimeter devices represent glaring weaknesses that require special attention due to the inherent vulnerabilities they contain.
