Ransomware attacks continue to be one of the most serious cybersecurity threats facing businesses today. To protect themselves, organizations and businesses need to proactively strengthen their information security systems and ensure the safety of their data and assets.
Organizations and businesses are increasingly facing malware attacks.
The victim's weak resistance
A cyberattack is the unauthorized intrusion into a computer system, website, database, network infrastructure, or device belonging to an individual or organization via the internet for illegal purposes.
Currently, there are many forms of attacks on organizations and businesses by hackers, such as malware attacks, zero-day vulnerability attacks, remote code execution attacks, attacks on e-commerce systems for extortion and information theft, targeted cyberattacks, social engineering attacks, phishing attacks, SMS smishing, and attacks through search engines...
Many factors contribute to organizations and businesses becoming targets of cyberattacks, including a lack of robust network and computer security measures; failure to update software, operating systems, and applications; and a lack of cybersecurity awareness among users. Due to this lack of understanding, many people open attachments from unknown sources or click on malicious links, inadvertently assisting cybercriminals in their attacks. Many attackers target the data repositories of organizations and businesses, gaining control of the data to threaten and demand ransom. Many organizations, after being attacked, lack a recovery plan, leading to further attacks, and subsequent recovery becomes extremely difficult.
With the constant changes and developments in science and technology, the techniques and tactics for ransomware attacks have also changed significantly. When ransomware infects a computer, it encrypts or blocks access to data of organizations and businesses. To restore normal operations, users must transfer money to an account to remove the ransomware. Globally, ransomware attacks on small and medium-sized enterprises have increased by 150% in the past two years. In Vietnam, according to statistics from NCS Cybersecurity Company, in the first six months of this year, there were 5,100 cyber security attacks on systems.
Cybersecurity is not an ordinary investment.
With the mindset of "if it's not broken, why replace it?", many organizations and businesses believe that the solutions they have already invested in are sufficient, and there is no need to invest more budget in new solutions.
Indeed, most physical assets will last for many years before needing replacement. Organizations and businesses can comfortably retain outdated IT hardware and software for years, only updating them when necessary. However, the flexibility of the security landscape has made the field of cybersecurity unique. For example, antivirus software was an indispensable defense tool for a long time, but today, cybercriminals have bypassed standard antivirus software and can launch continuous attacks. This requires a more advanced defense tool to protect the information security of each organization and business.
To prevent attacks and mitigate their impact on system operations, organizations and businesses need to implement several measures. First, back up data; the most effective way to handle ransomware attacks is to use the 3-2-1 backup rule: store at least three separate versions of data on two different storage types, with at least one external copy.
In addition, utilize third-party security services. Hiring a consultant or a managed security service provider (MSSP) to conduct regular system audits and assessments can significantly reduce the risk of attacks. When choosing a partner, clearly define the scope of the assessment. This is a crucial step to ensure the best possible results. Over time, ransomware attack techniques have evolved and become increasingly diverse. Phishing remains the initial step in an attack. Investing in anti-phishing software and training is essential. Simultaneously, ensure that selective alert configurations are continuously improved.
Every organization and business also needs to develop a ransomware defense plan. This plan helps determine who is responsible and the necessary steps to prevent, combat, and handle a ransomware attack. Finally, consider purchasing ransomware insurance. Similar to car insurance, this is a fairly common business practice today. The average cost for a company of 50 people is only $2,000-$3,000 per year, significantly less than the consequences of an attack.
Overall, cybersecurity is a field constantly evolving, adapting protective technologies, both direct and indirect, to enable systems to defend against cyberattacks. To avoid becoming victims of serious cyberattacks, organizations and businesses must keep pace with the rapid development of new technologies, balancing budgets and resources while still ensuring security needs are met.
