Ransomware is a type of malicious software designed to block access to a computer system or encrypt files until a ransom payment is made. This cyber threat can be devastating, leading to significant financial losses and operational disruptions. In recent years, ransomware attacks have evolved to include double-extortion and even triple-extortion tactics. In these scenarios, ransomware attackers not only encrypt files but also threaten to steal data and leak sensitive information if the ransom isn’t paid. This added layer of threat makes ransomware one of the most formidable cyber threats today. The modern ransomware craze began with the WannaCry outbreak of 2017, which highlighted the global scale and impact of such attacks.

Ransomware spreads in different ways, but these are the most common:

• Various forms of malware, including Trojans, are often employed by hackers to deliver ransomware to devices.
• Phishing Emails: Cybercriminals disguise emails to look like they’re from a trusted source. One wrong click on a link or attachment, and boom – your system is infected.

• Malicious Websites: Clicking on a compromised website can trigger an automatic download of malware.
• Weak Passwords & Remote Desktop Protocol (RDP): If your business uses RDP, hackers can break in by guessing passwords or using stolen credentials.
• Unpatched Software: Attackers exploit known vulnerabilities in outdated systems to gain entry.
• Malvertising: Online ads embedded with malware can infect users who simply view the page.
• USB and Hardware Exploits: Infected USB drives or compromised external devices can be used as an entry point.
• Social Engineering: Hackers manipulate employees into granting access through deception and impersonation tactics.

Once inside, ransomware quickly encrypts your files, making them inaccessible. These encrypted files remain inaccessible even in safe mode, highlighting the severity of the attack. Many ransomware variants can spread across networks after initial infection, targeting multiple devices and systems. Some ransomware strains even target backups, making recovery nearly impossible unless you have offline backups in place.

• File Encryption Methods: Some ransomware encrypts individual files, while others lock entire systems.
• Double Extortion Tactics: Some hackers not only encrypt your files but also threaten to release sensitive data if the ransom isn’t paid.
• Ransom Notes & Timers: Many ransomware attacks come with countdown timers, increasing pressure to pay.

The hackers then demand a ransom payment, usually in cryptocurrency, in exchange for a decryption key. But paying is risky – there’s no guarantee they’ll actually give you back your data. Hackers may even install additional malware to maintain access and extort you again later. Here’s what you need to know about ransoms:

• Varied Ransom Amounts: Some ransom payments are a few thousand dollars, while others exceed millions.
• Increased Targeting of SMBs: Small and mid-sized businesses (SMBs) are targeted more often because they lack strong defenses.
• Multiple Ransom Demands: Some cybercriminals demand additional payments even after the initial ransom is paid.
• High Prevalence: 59% of companies experienced a ransomware attack last year, resulting in average financial losses of over $2 million per incident.

Cybercriminals are using artificial intelligence (AI) to automate attacks, making them faster and more effective. AI can craft ultra-realistic phishing emails, crack passwords faster, and even find security vulnerabilities before anyone else.

RaaS works just like any subscription-based software – except it’s for cybercriminals. Hackers with little technical skill can now “rent” ransomware and launch attacks, meaning even more businesses at risk. RaaS platforms offer various ransomware variants, each with unique methods of infection and extortion tactics.

More devices are connected to the internet than ever before. Every smart device – whether it’s a printer, security camera, or conference room tablet – is a potential entry point for hackers.

With anonymous digital currencies like Bitcoin, cybercriminals can easily collect ransoms while remaining untraceable.

Remote work increases security risks for 2 main reasons:

1. Employees use personal devices that may lack security protections.
2. Remote work environments make phishing and social engineering attacks easier to execute.

Remote work environments are particularly vulnerable to ransomware infection due to the use of personal devices and unsecured networks.

Anyone and everyone. If you have a device of any kind that connects to the internet, you are at risk of being the next victim of a ransomware attack. Businesses of all sizes need to do what they can to secure their business not only to protect their data but to keep their business running. Ransomware victims often face significant financial and operational disruptions, and paying the ransom does not guarantee data recovery. Updating devices frequently can protect against ransomware and reduce the risk of infection.

One of the immediate issues with ransomware is downtime. With data and applications locked up, the first thing to happen is loss of productivity which is costly for business and the longer your systems are down, the more expensive it gets. Ransomware payments can be substantial, often reaching into the millions, adding to the overall cost of the attack. The average cost of a ransomware breach is over $5 million.

Depending on the severity of the ransomware attack, it can also cost you your reputation. Hackers can steal valuable personal information on you or your clients and customers and this can affect future business. People expect this personal information to be kept private and it’s your responsibility as a business to make sure it is kept safe.

Legal action may also take place if you are not adequately securing personally identifiable information. It varies from business to business, but it’s likely there are some kind of regulation and compliance measures that you are required to follow in your industry such as HIPAA or GDPR. Organizations should report ransomware attacks to the appropriate authorities before paying a ransom.

Having backup copies of critical data can limit the loss of data in the case of ransomware attacks or any other case of potential data loss.
Hackers will also target your backups, so you should also ensure that you keep your backups in a secure location where they cannot be edited or deleted.

Using comprehensive security software is also a must. Relying on devices’ default security settings is not enough and hackers find their way through those firewalls all the time. It is critical that you go the extra mile for security on devices and keep all software up to date.

As mentioned earlier, human error is one of the most common causes for ransomware attacks. You should be on the lookout for phishing emails and messages and other socially engineered scams. When visiting websites, make sure the URLs contain ‘https:’ and not ‘http:’. Also, avoid using public WiFi – this is a common place for hackers to gain access to devices connected to shared networks. An overall rule of thumb is to not open or click on anything from someone you don’t know. Don’t open emails from a questionable address, click on random links, and don’t click on weird-looking advertisements online.

To go off of safe surfing, you should also be educating your employees with this kind of information. Implementing a cyber awareness training program gets all your users up to date on the latest cyber threats. A program also teaches your employees cyber security best practices they can follow everyday to keep themselves and your business safe. Organizations can also benefit from guidelines provided by the Cybersecurity and Infrastructure Security Agency (CISA) to enhance their training programs.

Because user credentials are often the first target for hackers, it’s important to set-up multi-factor authentication to verify the login of a user. To add to this, you should also use password managers like LastPass to generate strong and unique passwords. Another benefit of these password managers is they keep all of your login credentials in a secure locker.

Having a robust cyber incident response plan is crucial for effectively dealing with ransomware attacks. This plan should outline procedures for detecting and analyzing the attack, reporting it to relevant authorities, and containing and eradicating the malicious code. Additionally, it should include steps for restoring systems and data. Communication is key during a ransomware attack, so having a plan to inform stakeholders and employees about the incident and response efforts is essential. Regular training and exercises can ensure that your incident response team is prepared to act swiftly and effectively in the face of a ransomware attack.

Reducing the attack surface is a critical strategy in preventing ransomware infections. This involves implementing security controls such as firewalls, intrusion detection and prevention systems, and antivirus software. Regular patch management and vulnerability scanning are also essential to identify and fix vulnerabilities that ransomware attackers could exploit. Additionally, adopting a least privilege access model and limiting user privileges can significantly reduce the risk of ransomware infections. Whitelisting software can block unauthorized programs and attacks, further enhancing security. By minimizing the attack surface, organizations can make it much harder for ransomware attackers to gain access to their systems and data, thereby enhancing their overall cyber security posture.

The short answer is no and there are a number of reasons for this. First, you have to remember that you are dealing with criminals who aren’t here to play fair. If you roll over and pay the ransom right away, there is nothing stopping them from exploiting you even more. Paying the ransom actually sets you up to be a recurring target. If the hackers know they can get the ransom money from you, they’ll likely keep retargeting you.

Even if you do pay the ransom, you might not get the decryption key or any of your files back. Or, if you do get the decryption key, there is a chance it won’t work – again, you’re dealing with criminals here. Hackers also often sell the information they stole from you on the black market. Selling personally identifiable information is a great money maker for hackers. Even if you do get all that information back, someone else might have a copy too.

Finally, you’ll be keeping the hackers in business. By handing over a large sum of money, not only are you now down a significant amount of money but you have also essentially funded them to go on to hack more people.

If you’re aware of an active ransomware infection going on in your network, here are some steps that should be taken right away:

The first thing you should do is disconnect whatever devices are infected from any others on the network. This might mean turning off the network, unplugging the WiFi – whatever you can do to ensure the ransomware doesn’t spread.

Backup all files, whether encrypted or not, that you can in case the hacker removes or deletes them because a decryption solution may become available to you later on.

Prioritizing the recovery of critical systems first ensures the business will be back up and running as soon as possible (even if it’s not fully up to par right away).

Completely clear out the infected devices (once backed up) to remove the malware. You can restore the device once it has been wiped.

Not everyone is able to remove the ransomware or recover on their own and that’s what companies like Lighthouse are here for. We can help you to remove malware and get everything up and running like normal.

The best thing you can do after ransomware is to consult a cybersecurity professional to find any vulnerabilities hiding in your systems. Hackers commonly retarget victims of a ransomware attack because they know they can gain access.
