Niterói Ransomware Filtering and Removal Consulting

Ransomware has been widely adopted by cybercriminals and malicious states, posing a potentially existential risk to businesses that fall victim. Modern versions of crypto-ransomware target everything, including backup, making even selective restoration a challenging and costly exercise. Novel versions of ransomware such as Ryuk, Maze, Sodinokibi, Netwalker, Phobos, Conti and Nephilim have made the headlines, replacing Locky, Cerber, and Petya in notoriety, elaborateness, and destructiveness.

Most ransomware breaches are the result of innocuous-looking emails with malicious hyperlinks or file attachments, and many are "zero-day" variants that elude the defenses of legacy signature-based antivirus filters. Although user education and frontline identification are critical to protect your network against ransomware attacks, best practices dictate that you take for granted some attacks will eventually succeed and that you put in place a solid backup mechanism that enables you to repair the damage rapidly with minimal damage.

Progent's ProSight Ransomware Vulnerability Checkup is an ultra-affordable service built around an online interview with a Progent security expert experienced in ransomware defense and recovery. During this interview Progent will work directly with your Niterói IT managers to gather pertinent data about your security configuration and backup processes. Progent will use this information to produce a Basic Security and Best Practices Report documenting how to follow leading practices for implementing and administering your cybersecurity and backup systems to block or recover from a ransomware assault.

Progent's Basic Security and Best Practices Report highlights vital areas associated with ransomware defense and restoration recovery. The review addresses:

Security

• Correct use of admin accounts
• Appropriate NTFS (New Technology File System) and SMB permissions
• Optimal firewall setup
• Secure Remote Desktop Protocol (RDP) connections
• Recommend AntiVirus (AV) tools identification and configuration

• Split permission model for backup integrity
• Backing up key servers such as Active Directory
• Geographically dispersed backups with cloud backup to Azure

About Ransomware
Ransomware is a variety of malware that encrypts or steals a victim's files so they cannot be used or are publicized. Ransomware sometimes locks the target's computer. To avoid the carnage, the victim is asked to send a certain amount of money, typically in the form of a crypto currency like Bitcoin, within a brief time window. There is no guarantee that delivering the ransom will recover the lost files or prevent its publication. Files can be encrypted or deleted throughout a network depending on the victim's write permissions, and you cannot solve the strong encryption algorithms used on the compromised files. A common ransomware attack vector is spoofed email, in which the user is lured into responding to by means of a social engineering exploit called spear phishing. This makes the email message to appear to come from a trusted sender. Another popular vulnerability is an improperly protected RDP port.

CryptoLocker ushered in the modern era of crypto-ransomware in 2013, and the monetary losses attributed to by the many versions of ransomware is estimated at billions of dollars annually, roughly doubling every other year. Notorious attacks are WannaCry, and Petya. Current high-profile threats like Ryuk, DoppelPaymer and CryptoWall are more complex and have wreaked more havoc than older strains. Even if your backup procedures enable you to restore your encrypted data, you can still be threatened by so-called exfiltration, where ransomed documents are made public. Because additional versions of ransomware crop up daily, there is no guarantee that conventional signature-based anti-virus filters will block the latest attack. If an attack does appear in an email, it is important that your end users have been taught to be aware of social engineering tricks. Your last line of protection is a sound process for performing and retaining offsite backups plus the use of reliable restoration platforms.
