Ransomware has been weaponized by the major cyber-crime organizations and rogue states, posing a possibly existential threat to businesses that are successfully attacked. The latest variations of crypto-ransomware go after all vulnerable resources, including backup, making even selective recovery a long and expensive exercise. Novel variations of ransomware like Ryuk, Maze, Sodinokibi, Mailto (aka Netwalker), DopplePaymer, LockBit and Nephilim have made the headlines, displacing WannaCry, Cerber, and CryptoWall in notoriety, sophistication, and destructiveness.
Most crypto-ransomware infections are caused by innocuous-looking emails with malicious links or file attachments, and many are so-called "zero-day" variants that elude detection by traditional signature-matching antivirus filters. While user training and frontline detection are important to defend against ransomware attacks, best practices demand that you assume some malware will eventually succeed and that you implement a strong backup solution that allows you to recover quickly with minimal damage.
Progent's ProSight Ransomware Vulnerability Checkup is an ultra-affordable service built around a remote discussion with a Progent cybersecurity expert experienced in ransomware defense and repair. During this interview Progent will cooperate with your Brisbane IT managers to gather critical data concerning your cybersecurity posture and backup environment. Progent will use this data to produce a Basic Security and Best Practices Assessment detailing how to adhere to best practices for implementing and administering your cybersecurity and backup systems to prevent or clean up after a crypto-ransomware assault.
Progent's Basic Security and Best Practices Assessment focuses on key issues associated with ransomware defense and restoration recovery. The review addresses:
Ransomware is a form of malware that encrypts or steals a victim's files so they cannot be used or are made publicly available. Crypto-ransomware often locks the victim's computer. To prevent the damage, the victim is asked to send a certain amount of money, usually in the form of a crypto currency like Bitcoin, within a short time window. It is never certain that paying the extortion price will restore the damaged data or prevent its exposure to the public. Files can be encrypted or erased across a network depending on the victim's write permissions, and you cannot solve the strong encryption technologies used on the hostage files. A typical ransomware delivery package is tainted email, in which the user is tricked into interacting with by a social engineering exploit known as spear phishing. This makes the email to look as though it came from a trusted source. Another popular vulnerability is a poorly protected Remote Desktop Protocol (RDP) port.
The ransomware variant CryptoLocker opened the new age of ransomware in 2013, and the monetary losses attributed to by the many strains of ransomware is estimated at billions of dollars per year, roughly doubling every two years. Notorious attacks are WannaCry, and NotPetya. Recent headline variants like Ryuk, Sodinokibi and Spora are more elaborate and have wreaked more havoc than older versions. Even if your backup/recovery procedures allow you to restore your ransomed data, you can still be hurt by so-called exfiltration, where ransomed data are exposed to the public (known as "doxxing"). Because additional variants of ransomware are launched daily, there is no certainty that traditional signature-matching anti-virus filters will detect a new malware. If threat does show up in an email, it is important that your users have been taught to identify phishing tricks. Your ultimate defense is a sound process for performing and retaining offsite backups and the deployment of reliable restoration tools.
