Bristol Ransomware Prevention and Remediation Expertise
Ransomware Susceptibility Audit
Ransomware has become the weapon of choice for cyber extortionists and malicious governments, representing a potentially lethal threat to businesses that are successfully attacked. Modern strains of ransomware go after all vulnerable resources, including online backup, making even selective restoration a long and costly exercise. Novel versions of crypto-ransomware such as Ryuk, Maze, Sodinokibi, Netwalker, DopplePaymer, Snatch and Nephilim have made the headlines, displacing WannaCry, Spora, and NotPetya in notoriety, sophistication, and destructive impact.
Most crypto-ransomware infections are the result of innocuous-seeming emails that have malicious hyperlinks or attachments, and a high percentage are so-called "zero-day" attacks that elude the defenses of legacy signature-based antivirus (AV) tools. Although user education and up-front identification are critical to protect against ransomware attacks, best practices demand that you expect that some attacks will inevitably succeed and that you implement a strong backup solution that enables you to repair the damage quickly with little if any damage.
Progent's ProSight Ransomware Vulnerability Report is a low-cost service centered around a remote discussion with a Progent cybersecurity consultant skilled in ransomware defense and recovery. During this interview Progent will collaborate directly with your Bristol network management staff to collect critical data about your security posture and backup processes. Progent will use this data to create a Basic Security and Best Practices Report documenting how to follow leading practices for implementing and managing your security and backup systems to prevent or clean up after a crypto-ransomware attack.
Progent's Basic Security and Best Practices Assessment focuses on vital issues related to crypto-ransomware prevention and restoration recovery. The review addresses:
Security
- Proper allocation and use of administration accounts
- Assigning NTFS (New Technology File System) and SMB (Server Message Block) authorizations
- Proper firewall setup
- Secure Remote Desktop Protocol connections
- Recommend AntiVirus (AV) filtering identification and configuration
- Split permission architecture for backup integrity
- Protecting key servers such as Active Directory
- Offsite backups with cloud backup to Microsoft Azure
About Ransomware
Ransomware is a variety of malicious software that encrypts or deletes files so they are unusable or are publicized. Ransomware often locks the victim's computer. To avoid the damage, the target is asked to pay a specified ransom, typically via a crypto currency like Bitcoin, within a brief period of time. It is not guaranteed that paying the extortion price will recover the lost files or prevent its publication. Files can be altered or erased throughout a network based on the victim's write permissions, and you cannot break the strong encryption technologies used on the hostage files. A typical ransomware attack vector is booby-trapped email, whereby the user is lured into interacting with by means of a social engineering technique called spear phishing. This causes the email to appear to come from a familiar source. Another common attack vector is a poorly secured Remote Desktop Protocol (RDP) port.
The ransomware variant CryptoLocker opened the new age of crypto-ransomware in 2013, and the monetary losses caused by different strains of ransomware is estimated at billions of dollars annually, roughly doubling every two years. Famous examples include WannaCry, and NotPetya. Recent headline variants like Ryuk, Maze and CryptoWall are more elaborate and have wreaked more havoc than older strains. Even if your backup/recovery procedures permit you to recover your ransomed files, you can still be threatened by so-called exfiltration, where stolen documents are made public (known as "doxxing"). Because additional variants of ransomware are launched every day, there is no certainty that traditional signature-based anti-virus filters will block a new attack. If threat does appear in an email, it is critical that your end users have learned to identify phishing tricks. Your last line of defense is a solid scheme for performing and keeping offsite backups plus the use of dependable restoration platforms.
