How to Spot the Early Signs of a Ransomware Attack

By: Brittany Holmes, Corporate Communications Manager 

The threat of ransomware attacks looms large over organizations of all sizes. It is predicted that ransomware will cost, in total, USD $265 billion annually by 2031, up from USD $42 billion in 2024. This serves as a reminder of the importance of proactive cybersecurity measures in staying ahead of these malicious attacks, especially when they’re predicted to arise with new challenges.  

There is hope in the form of advanced defense mechanisms that can proactively prevent and detect ransomware attacks before they cause irreparable harm. This blog explores early signs of a ransomware attack and how organizations can level up their defenses to mitigate the risk.   

How Ransomware Attacks Work 

Ransomware is a type of malicious software that blocks a user’s access to their computer files by encrypting them. The cybercriminals demand a ransom payment in exchange for unlocking the files. This coercive tactic puts victims in a predicament where paying the ransom is often seen as the most straightforward and cost-effective way to regain access to their data. In some cases, ransomware may also involve data theft to further pressure targets into meeting the ransom demands. 

A prime example is when the MGM Resorts data breach shook the industry. This breach resulted in the personal information of more than 10.6 million guests being exposed on the dark web after the company refused to pay the ransom demanded by the cybercriminals. It was reported that MGM faced $100 million in financial losses. This incident showcases what can happen if an employee falls victim to a simple social engineering tactic via a fraudulent phone call. 

Recognizing Early Signs of a Ransomware Attack 

Being vigilant and proactive in recognizing early signs of a potential attack is crucial: 

  • Tailored and Targeted Campaigns: For example, a rise in phishing attempts, seen through an increase in spam emails, can indicate potential malware threats. This puts the entire network at risk, as an employee clicks on a malicious link or download can lead to infection. Vigilance is key in recognizing and responding to this threat promptly. 
  • Abnormal network activity: Sudden increases in traffic from unknown sources may signify unauthorized access attempting to exfiltrate data. In addition, unexpected data transfers can be a sign of ransomware encrypting files for extortion purposes. The presence of unfamiliar file extensions or files being created/modified without authorization can indicate the presence of malicious software attempting to compromise the network. 
  • Failed 2FA Authentication: Cybercriminals often try to bypass two-factor authentication to gain control and encrypt important data, leading to potential extortion demands. Monitoring and responding promptly to failed authentication attempts can help prevent the escalation of a ransomware attack and protect critical assets from being compromised. 

What is The Impact of a Ransomware Attack?  

The consequences become more severe for the targeted organization when a ransomware attack is successful. Data encryption and demands for ransom payment disrupt normal operations, leading to potential financial losses and downtime. After a successful ransomware attack, organizations may face long-lasting repercussions such as stolen assets, including intellectual property and sensitive customer information.   

The reputational damage from a data breach can cause clients and stakeholders to lose trust, impacting the organization’s standing in the industry. In addition, financial penalties for failing to secure sensitive data can add to the attack’s overall cost. 

By staying vigilant and updating defenses at the first sign of a threat, organizations can significantly reduce their exposure to ransomware attacks and safeguard their critical data and systems. 

Strengthening Ransomware Defense Mechanisms 

Implementing strong cybersecurity measures, conducting regular security assessments, and training employees on cybersecurity best practices can help amplify defenses against evolving cyber threats. Remember, early detection and quick response are key to mitigating the impact of ransomware attacks and safeguarding the integrity and resilience of your organization’s digital infrastructure. 

Embracing technologies like Adlumin’s Total Ransomware Defense and Managed Detection and Response (MDR) can provide organizations with the multi-layered protection they need to stay one step ahead of cyber threat actors. By leveraging AI and behavioral models to identify warning signs of ransomware at different attack layers, these solutions can effectively block malicious files from executing and mitigate the risk of data encryption and extortion. 

The ability of these solutions to provide automated detection updates ensures that organizations are constantly shielded from evolving ransomware variants. By staying vigilant and updating defenses at the first sign of a threat, organizations can significantly reduce their exposure to ransomware attacks and safeguard their critical data and systems.
