The Ransomware Threat in the Contemporary OrganizationsBy X PHY / May 28, 2021 June 6, 2022 Ransomware attacks are costly to organizations when the hackers become successful in locking the company data and demanding certain reimbursement for the files to be released. Take, for example, the Colonial Pipeline Ransomware Attack. Many companies have lost millions in the process and this largely comes as a result of negligence which is most of the time preventable if the correct measures of protection are considered. The American oil pipeline system, Colonial Pipeline is the recent victim of the ransomware attacks that saw the company squander millions of dollars to restore its thwarted business process and reclaim its image which was severely damaged in the face of the public. The Colonial Pipeline Ransomware Attack Early May this year, the Colonial Pipeline ransomware attack was brought to light when an employee found a message from hackers in one of the server room computers. Not long after receiving the ransom note, the company CEO Joseph Blount decided to pay off the ransom so that they can reclaim their system and get their service provision going after an unprecedented halt of the activities caused by the disrupted system. The CEO made the hard decision of paying the hackers $4.4 million with the boss stating that they had to take that decision because they did not understand how badly their system was compromised and hence not knowing the exact amount of time it would have taken to restore the system and get the pipeline back on track.Mr. Blount defended what he termed as a bold and the only plausible choice he had left, given the criticality of the infrastructure they were running. The famed Colonial Pipeline is known for its enormous contribution to the economic continuation in the East Coast providing a rough estimate of over 45% of the fuel supply in the area. Acknowledging that it was a controversial decision he undertook, Mr. Blount tried to explain to the public the massive breach that could have further been caused by the elongated time to pay the ransom to the hackers. How Colonial Pipeline Ransomware Attack was executed The hacking mechanism used by the alleged hacking group Darkside is still largely speculation, with experts believing that the attack could be as a result of successful social engineering (phishing attacks) or brute force attacks that resulted in the hackers assuming administrative privileges and hence taking the whole system down. The steps below illustrate the mechanism of Darkside attack;1: Attack InitiationThe first step involves gaining access to a firm’s networks and systems through methods such as malicious phishing links, SQL-injections, and brute force password cracking methods. In the Colonial Pipeline Attack, it is believed that phishing was utilized to gain access credentials.2. Gaining AccessUntil now, cybersecurity experts have unearthed three sets of unique tactics that the attackers leverage to gain access to secure systems.Downloading and making use of TeamViewer.Making use of command and control (CS) infrastructureBackdoor methods such as keynoting, executing of .NET commands and taking 3. Ransomware InstallationAfter gaining privileged administrative access, the attackers make use of CertUtil.exe and PowerShell.exe in downloading and executing the Darkside code. In the process, a copy of the malware is saved in the infected device.4. Privilege EscalationTo install the ransomware, the three threat actors engage in an escalation of privilege. This is done using CVE-2020-1472, Mimikatz, and Local Security Authority Subsystem (LSASS).5. Files Encryption and Exfiltration of DataBecause they have already gained administrative privileges and downloaded the malicious code, they start the process of sensitive data collection. After they have collected all the needed data that they want to hold ransom, they encrypt it with the use of the copy of ransomware initially stored in a shared folder of the affected device. This gives them the ability to spread malicious code all over the organization network and system in form of scheduled tasks. X-PHY Protection DarkSide actors gained access to Colonial Pipeline system by use of administrative access credentials. Existing software defenses are only designed to protect against known threats, thus use of valid access credentials could not be detected as a threat. After gaining privileged administrative access, the attackers make used of CertUtil.exe and PowerShell.exe to download and execute the Darkside code. In this process, a copy of the malware is saved in the infected device. Once the Darkside code is injected, the XPHY Guard will immediately detect it as malicious due to the data access behavior.Guardian Pro-X and Security Scout features within the X-Guard Threat Lock use AI at the firmware level to survey a large amount of data in real-time to detect any anomalies in data access patterns. In this case, the extraction of data and encryption of files could have shown a disparity in the normal disk access pattern thus classified as malicious. As such, X-PHY Factor Encryption lock feature could trigger data lockdown to prevent the attacker from accessing it and in the process activate the Keycode 2-factor. At this point, X-PHY enters safe mode and data on the disk cannot be accessed until multidimensional authentication (MDA) codes are provided.Thus, this successful colonial pipeline ransomware attack causing a loss of millions suggests that organizations are in need of better cybersecurity measures.
