Security Mistakes That Make Life Easy for Ransomware Gangs

Over the past 12 months the number of successful ransomware attacks has increased sharply. Many attacks have been headline news due to the disruption they have caused and the high cost of remediation. The healthcare industry in the United States has been targeted, with the attacks disrupting patient care and putting patient safety at risk. Recently there was an attack on Colonial Pipeline that resulted in the shutdown of a main fuel pipeline serving the East Coast of the United States, while JBS suffered an attack that threatened food production at its U.S. plants.

Ransom payments have also increased and threat actors are stealing data prior to encrypting files to increase the pressure on victims to pay up. Regardless of whether the ransom is paid, the recovery process is slow. Many victims have suffered disruption to business operations for several months and businesses have been forced to permanently close after an attack due to the high costs of recovery.

Ransomware gangs have conducted highly sophisticated attacks but in the most part they have exploited vulnerabilities in security defenses that should not have existed. Most attacks exploit weaknesses that could have been easily addressed had network security best practices been followed. So what mistakes are businesses making that leaves them vulnerable to ransomware attacks?

Security Mistakes That Make Life Easy for Ransomware Gangs

In order for ransomware gangs to conduct a successful attack they must first gain access to the business network by exploiting security vulnerabilities.

Email Security

While there are many possible attack vectors, the most common is phishing. A phishing campaign is conducted with one of two aims: To steal credentials that allow perimeter defenses to be bypassed, or to install malware that gives the attackers persistent access to the network.

With credential theft, the aim is to obtain credentials of an individual with high-level privileges such as the CEO. With high privileges, an attacker can easily gain persistent access to the network and move laterally. Alternatively, campaigns can be conducted to target lower-level employees and trick them into installing malware.

Most businesses have implemented a spam filter to block malicious messages, but many rely on default Office 365 spam filters, which do not offer a high enough level of protection. Implementing an advanced AI-based spam filter with sandboxing will improve protection.

Multifactor Authentication

Stolen credentials allow an attacker to access network resources, but not if multi-factor authentication has been implemented. While not infallible, multi-factor authentication will prevent attackers from using stolen credentials to gain access to networks in the vast majority of cases.

Web Security

Anti-spam solutions and multi-factor authentication will provide protection from email attacks, but ransomware and other malware is often downloaded via the internet. By implementing a web filtering solution, employees can be prevented from visiting malicious websites and malware downloads can be blocked. Many businesses fail to protect against the web-based component of attacks.

Security Awareness Training

Many businesses rely on technical measures to block threats and neglect the human element. Attacks often target employees, so it is important for security awareness training to be provided and for regular refresher sessions to be conducted to reinforce training. Without training, employees cannot be expected to recognize and avoid threats.

Patching and Software Updates

Vulnerabilities in software, firmware, and operating systems are often exploited. Prompt patching is therefore important. It can be difficult to stay on top of patches and security updates, so patching should be prioritized. Many ransomware attacks have succeeded by exploiting years-old vulnerabilities. If vulnerabilities are not addressed, it will only be a matter of time before they are exploited.

Password Management

Brute force tactics to guess weak passwords are often effective. As well as creating password policies that require all default passwords to be changed and strong passwords to be set, those policies must be enforced. Provide employees with tools to make creating strong passwords easier, such as providing them with a password management solution.

Network Segmentation

In the event of an attack, it is vital that damage is limited. Network segmentation is important in this regard. If an attacker bypasses the perimeter defenses, they should not be able to access the entire network. Segmenting the network will limit the potential for lateral movement and minimize the damage that can be caused.

Incident Response Plan

Businesses that have prepared for the worst and have developed and tested an incident response plan will recover much faster and will be able to limit the harm caused. Importantly, the business will be able to continue to operate while the attack is remediated.

Data Backups

Many businesses mistakenly believe that having backups will allow them to recover quickly in the event of an attack when that is often not the case. Regular backups must be created, and those backups must be tested to make sure file recovery is possible and data have not been corrupted. One copy of a backup must also be stored on an isolated system or device that cannot be accessed from the network where the data resides.

By addressing these common security mistakes, ransomware gangs will find it much harder to breach defenses.

Webinar: June 30, 2021: Best Practices to Combat Phishing and Ransomware

The pandemic forced businesses to adopt different working practices. Rather than having employees working from the office, restrictions introduced to combat COVID-19 meant businesses had to allow their employees to work from home. Protecting business networks when virtually all workers are accessing those networks remotely was a major challenge and it was inevitable that vulnerabilities would be introduced that could potentially be exploited by threat actors.

Those vulnerabilities were exploited, with cybercriminals and APT groups targeting at-home workers mostly by exploiting vulnerabilities in remote access systems and through phishing attacks to obtain credentials to allow networks to be accessed. While these attacks had many different goals, one of the most common was to encrypt files using ransomware to prevent them from being accessed, usually with data theft prior to file encryption.

According to Osterman Research, the three main priorities for cybersecurity in 2021 are protecting endpoints, educating users about ransomware and stopping them becoming victims of attacks, and protecting backups from ransomware. The fact that two of the three main priorities are related to ransomware show just how serious the threat has become.

Protecting endpoints requires a combination of cybersecurity solutions, one of the most important being an advanced email security solution. Email is the attack vector of choice in cyberattacks and is commonly the initial attack vector in ransomware attacks. Phishing campaigns are easy to conduct and they target the weakest link in cybersecurity – employees. Further, with many employees working from home, phishing has become even easier. Studies have shown at-home employees have been taking security shortcuts, with many also admitting to clicking links in phishing emails and opening potentially malicious email attachments. When errors such as this are made, many employees fail to report the matter to their IT department out of fear of reprisals.

Cybersecurity training is important to teach and reinforce cyber hygiene best practices and raise awareness of the threat from ransomware. If employees are not taught how to identify phishing emails and ransomware, they cannot be expected to avoid those threats. With training, susceptibility to phishing can be greatly reduced. However, even with training employees will make mistakes and will fail to recognize every threat.

A recent study conducted by Osterman Research and TitanHQ looked into the main cybersecurity threats faced by security professionals in 2021. The biggest threats were found to be business email compromise (BEC) attacks that tricked employees, phishing messages that result in malware infections, and phishing messages that result in account compromises. The latter is usually the first step in a BEC attack. 85% of interviewed organizations said they had experienced at least one security incident in the past 12 months, and while security professionals were aware of the dangers of phishing and ransomware attacks, only 37% rated their defenses as highly effective.

Due to the lack of confidence in defenses against phishing and ransomware attacks identified by the study, TitanHQ and Osterman Research are hosting a webinar in which attendees will discover the most effective mitigations against phishing and ransomware attacks and will learn best practices they need to adopt to avoid those threats.

Webinar attendees will also learn about the full findings of the in-depth cybersecurity study into the rising threat from phishing and ransomware and how risk can be reduced to a low and acceptable level.

The webinar will be taking place on June 30, 2021:
