Curitiba Ransomware Protection and Cleanup Consulting
Ransomware Vulnerability Review
Ransomware has been widely adopted by cyber extortionists and bad-actor states, representing a possibly lethal threat to businesses that fall victim. Modern variations of ransomware target all vulnerable resources, including backup, making even partial restoration a complex and expensive exercise. New variations of ransomware like Ryuk, Maze, Sodinokibi, Netwalker, DopplePaymer, LockBit and Nephilim have made the headlines, displacing Locky, Cerber, and NotPetya in prominence, sophistication, and destructive impact.
Most crypto-ransomware breaches come from innocuous-seeming emails with malicious links or attachments, and a high percentage are "zero-day" variants that elude the defenses of legacy signature-matching antivirus (AV) tools. While user education and up-front detection are critical to defend against ransomware attacks, leading practices dictate that you take for granted some malware will eventually get through and that you prepare a solid backup solution that permits you to recover quickly with little if any damage.
Progent's ProSight Ransomware Vulnerability Report is an ultra-affordable service built around a remote discussion with a Progent security consultant experienced in ransomware protection and recovery. In the course of this assessment Progent will cooperate directly with your Curitiba network managers to gather pertinent information about your security configuration and backup processes. Progent will utilize this information to produce a Basic Security and Best Practices Report detailing how to adhere to best practices for configuring and managing your security and backup solution to prevent or recover from a crypto-ransomware attack.
Progent's Basic Security and Best Practices Assessment focuses on key issues associated with ransomware defense and restoration recovery. The report addresses:
Security
- Proper allocation and use of admin accounts
- Assigning NTFS (New Technology File System) and SMB (Server Message Block) permissions
- Proper firewall setup
- Safe RDP connections
- Advice about AntiVirus filtering selection and deployment
- Split permission architecture for backup integrity
- Protecting key servers such as AD
- Offsite backups with cloud backup to Microsoft Azure
About Ransomware
Ransomware is a type of malicious software that encrypts or deletes a victim's files so they cannot be used or are publicized. Crypto-ransomware often locks the victim's computer. To prevent the damage, the target is required to send a specified amount of money (the ransom), typically in the form of a crypto currency such as Bitcoin, within a short time window. It is not guaranteed that paying the extortion price will restore the damaged files or avoid its publication. Files can be encrypted or erased across a network based on the target's write permissions, and you cannot reverse engineer the military-grade encryption algorithms used on the hostage files. A common ransomware delivery package is tainted email, whereby the target is tricked into interacting with by a social engineering technique called spear phishing. This causes the email message to look as though it came 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 different versions of ransomware is estimated at billions of dollars annually, roughly doubling every two years. Notorious examples are Locky, and Petya. Current high-profile threats like Ryuk, Maze and CryptoWall are more sophisticated and have wreaked more damage than older strains. Even if your backup processes allow your business to restore your ransomed data, you can still be hurt by exfiltration, where stolen data are made public. Because additional versions of ransomware crop up daily, there is no guarantee that traditional signature-based anti-virus tools will detect the latest attack. If an attack does appear in an email, it is critical that your users have been taught to be aware of social engineering tricks. Your ultimate defense is a sound process for performing and retaining remote backups plus the deployment of dependable recovery tools.
