Brasília Ransomware Defense and Cleanup Consulting
Ransomware Vulnerability Evaluation
Ransomware has been widely adopted by the major cyber-crime organizations and rogue states, representing a possibly existential risk to companies that are successfully attacked. Modern variations of crypto-ransomware go after all vulnerable resources, including backup, making even selective recovery a long and costly exercise. New versions of ransomware such as Ryuk, Maze, Sodinokibi, Mailto (aka Netwalker), DopplePaymer, LockBit and Nephilim have made the headlines, displacing Locky, Spora, and NotPetya in notoriety, sophistication, and destructiveness.
Most crypto-ransomware penetrations come from innocent-seeming emails that include dangerous hyperlinks or file attachments, and many are so-called "zero-day" strains that can escape the defenses of legacy signature-matching antivirus (AV) tools. Although user education and frontline identification are important to protect your network against ransomware, best practices demand that you expect that some malware will eventually get through and that you prepare a strong backup solution that allows you to repair the damage rapidly with minimal damage.
Progent's ProSight Ransomware Vulnerability Assessment is a low-cost service centered around an online interview with a Progent security consultant experienced in ransomware protection and repair. During this interview Progent will cooperate with your Brasília network managers to collect pertinent information about your cybersecurity profile and backup environment. Progent will utilize this information to generate a Basic Security and Best Practices Assessment documenting how to follow best practices for configuring and managing your security and backup solution to prevent or clean up after a crypto-ransomware assault.
Progent's Basic Security and Best Practices Report focuses on key issues related to crypto-ransomware prevention and restoration recovery. The report addresses:
Cybersecurity
- Effective use of admin accounts
- Appropriate NTFS and SMB (Server Message Block) authorizations
- Proper firewall configuration
- Secure Remote Desktop Protocol access
- Guidance for AntiVirus (AV) filtering selection and deployment
- Split permission model for backup protection
- Backing up key servers including AD
- Offsite backups with cloud backup to Azure
About Ransomware
Ransomware is a variety of malware that encrypts or deletes files so they are unusable or are publicized. Ransomware sometimes locks the victim's computer. To avoid the damage, the victim is asked to pay a certain amount of money, typically in the form of a crypto currency like Bitcoin, within a brief period of time. It is never certain that delivering the extortion price will restore the damaged data or prevent its publication. Files can be encrypted or erased throughout a network based on the victim's write permissions, and you cannot reverse engineer the military-grade encryption algorithms used on the compromised files. A typical ransomware attack vector is tainted email, whereby the user is lured into responding to by means of a social engineering technique known as spear phishing. This makes the email to look as though it came from a trusted source. Another common vulnerability is a poorly protected Remote Desktop Protocol port.
The ransomware variant CryptoLocker ushered in the new age of ransomware in 2013, and the monetary losses caused by the many strains of ransomware is estimated at billions of dollars annually, more than doubling every other year. Famous attacks are Locky, and Petya. Recent headline threats like Ryuk, DoppelPaymer and CryptoWall are more sophisticated and have wreaked more havoc than earlier strains. Even if your backup/recovery procedures permit you to recover your ransomed data, you can still be threatened by exfiltration, where ransomed documents are exposed to the public (known as "doxxing"). Because new variants of ransomware are launched every day, there is no certainty that traditional signature-based anti-virus tools will block the latest malware. If an attack does appear in an email, it is important that your end users have been taught to identify phishing tricks. Your last line of protection is a sound process for performing and keeping offsite backups and the deployment of reliable recovery tools.
