Sydney Ransomware Filtering and Restoration Expertise
Ransomware Readiness Checkup
Ransomware has been weaponized by cyber extortionists and bad-actor states, representing a possibly lethal risk to businesses that are victimized. The latest variations of crypto-ransomware go after everything, including online backup, making even partial recovery a challenging and expensive exercise. Novel strains of crypto-ransomware such as Ryuk, Maze, Sodinokibi, Netwalker, Phobos, Conti and Nephilim have emerged, replacing WannaCry, TeslaCrypt, and Petya in notoriety, elaborateness, and destructive impact.
90% of ransomware penetrations are caused by innocent-looking emails with malicious links or attachments, and a high percentage are so-called "zero-day" attacks that can escape detection by traditional signature-based antivirus tools. Although user training and frontline detection are important to defend against ransomware, leading practices dictate that you take for granted some malware will inevitably succeed and that you deploy a strong backup solution that permits you to recover quickly with little if any damage.
Progent's ProSight Ransomware Vulnerability Report is a low-cost service built around a remote discussion with a Progent security consultant experienced in ransomware protection and repair. In the course of this interview Progent will work with your Sydney IT management staff to gather critical information about your security setup and backup processes. Progent will use this information to generate a Basic Security and Best Practices Report detailing how to adhere to leading practices for configuring and managing your security and backup solution to block or clean up after a ransomware attack.
Progent's Basic Security and Best Practices Report focuses on key issues associated with crypto-ransomware defense and restoration recovery. The review addresses:
Cybersecurity
- Effective use of administration accounts
- Appropriate NTFS (New Technology File System) and SMB (Server Message Block) authorizations
- Optimal firewall setup
- Secure Remote Desktop Protocol (RDP) connections
- Recommend AntiVirus filtering selection and deployment
- Split permission model for backup integrity
- Backing up critical servers such as Active Directory
- Geographically dispersed backups including cloud backup to Azure
About Ransomware
Ransomware is a type of malicious software that encrypts or steals a victim's files so they cannot be used or are publicized. Ransomware often locks the target's computer. To avoid the carnage, the victim is required to send a specified ransom, usually in the form of a crypto currency such as Bitcoin, within a brief time window. There is no guarantee that delivering the ransom will restore the lost data or avoid its exposure to the public. Files can be encrypted or erased throughout a network depending on the target's write permissions, and you cannot reverse engineer the military-grade encryption algorithms used on the hostage files. A common ransomware attack vector is booby-trapped email, whereby the user is lured into responding to by a social engineering exploit called spear phishing. This causes the email message to appear to come from a familiar source. Another common attack vector is an improperly secured RDP port.
CryptoLocker ushered in the modern era of crypto-ransomware in 2013, and the damage attributed to by the many strains of ransomware is estimated at billions of dollars per year, more than doubling every other year. Famous attacks are Locky, and NotPetya. Current headline threats like Ryuk, Maze and Spora are more sophisticated and have caused more damage than earlier strains. Even if your backup procedures allow 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 new versions of ransomware crop up every day, there is no certainty that conventional signature-matching anti-virus tools will detect the latest attack. If an attack does appear in an email, it is critical that your end users have learned to identify social engineering techniques. Your ultimate defense is a sound scheme for performing and keeping offsite backups plus the deployment of reliable restoration tools.
