Ransomware is an advanced type of malware that encrypts sensitive data and files. An enhanced virus or piece of malicious code locks you out of certain files or out of your system. In some cases, ransomware is confined to a single hard drive or server. In other cases it can spread through an entire network, where gigabytes of files are encrypted leading to wide-spread data loss for an organisation. Typically cybercriminals issue a ransom demand on-screen, usually asking for the ransom to be paid in cryptocurrency.
If ransomware is deployed onto your system and you have sensitive data which is encrypted, we strongly advise you not to pay the ransom. There is no guarantee that you will recover any data by doing so, nor will it necessarily be intact. Please get in touch if you need any assistance with ransomware recovery.
Most commonly, ransomware is distributed through multiple cyber-attacks. Phishing emails are perhaps the most typical method of distribution. These emails might contain attachments or a single attached firewall that automatically executes on your computer once downloaded. This then encrypts the hard drive, and in some cases spreads throughout your entire network. Usually by this point, an on-screen note will appear demanding a ransom to be paid to a cryptocurrency wallet in exchange for the return of sensitive data and access to systems.
Employers must consider regular and up-to-date training on phishing attacks for employees. This is the most common method of ransomware distribution, and keeping your employees well aware of phishing emails puts you a step ahead of cyber criminals. Our own Phishing Service provides realistic phishing simulations, where you can train your employees and get reports in real-time. You can find out more here.
Step 1 – Impact Assessment
Step 2 – Ransomware Removal
Step 3 – Ransomware Prevention
Taking the necessary steps to analyse the impact of the ransomware across your networks and computers. Preventing the ransomware virus from further spreading and then determining the path of infection. Finally we, identify where your current backups are stored and the sensitivity of encrypted files.
We’ve developed specialist tools to recover data from ransomware encrypted systems. We’ll work closely with you to decrypt sensitive files and remove any traces of ransomware. Our professionals can help you effectively respond to the incident, remove cyber criminals from your network and restore your computer systems.
Once as much of your data as possible is recovered and we’ve restored your systems functionality, we can assist you with putting in place appropriate cyber security tools to reduce the risk of encountering a similar cyber attack in the future. We offer services such ranging from Phishing Awareness Training for your employees, right the way to a Managed Security Operations Centre which helps you detect and respond to cyber incidents 24/7.
