  4. How to remove ransomware - There is no guarantee that victims can stop a ransomware attack and regain their data; however, there are methods that may work in some cases. For example, victims can stop and reboot their system in safe mode, install an antimalware program, scan the computer and restore the computer to a previous, noninfected state. - Victims could also restore their system from backup files stored on a separate disk. If they are in the cloud, then victims could reformat their disk and restore from a previous backup. - Windows users specifically could use System Restore, which is a function that rolls Windows devices and their system files back to a certain marked point in time -- in this case, before the computer was infected. For this to work, System Restore needs to be enabled beforehand so that it can mark a place in time for the computer to return to. Windows enables System Restore by default. - For a general step-by-step process in identifying and removing the ransomware, follow these recommendations: 1.Create a system backup, and back up all important or integral files. If an organization cannot recover its files, it will be able to restore from a backup. 2.Ensure system optimization or cleanup software does not remove the infection or other necessary ransomware files. The files must first be isolated and identified. 3.Quarantine the malware using antimalware software. Also, make sure the attackers did not create a backdoor that can allow them to access the same system at a later date. 4.Identify the ransomware type and exactly which encryption method was used. Decryptor and ransomware recovery tools can help determine the type of ransomware. 5.Once identified, ransomware recovery tools can be used to decrypt files. Because of the different and evolving methods of ransomware, there is no absolute guarantee that the tool will be able to help. Ransomware recovery tools include products such as McAfee Ransomware Recover and Trend Micro Ransomware File Decryptor.
  5. How do you prevent ransomware attacks ? To protect against ransomware threats and other types of cyberextortion, security experts urge users to do the following: - Back up computing devices regularly. - Inventory all assets. - Update software, including antivirus software. - Have end users avoid clicking on links in emails or opening email attachments from strangers. - Avoid paying ransoms. - Avoid giving out personal information. - Do not use unknown USB sticks. - Only use known download sources. - Personalize antispam settings. - Monitor the network for suspicious activity. - Use a segmented network. - Adjust security software to scan compressed and archived files. - Disable the web after spotting a suspicious process on a computer. While ransomware attacks may be nearly impossible to stop, individuals and organizations can take important data protection measures to ensure that damage is minimal and recovery is as quick as possible. Strategies include the following: • Compartmentalize authentication systems and domains. • Keep up-to-date storage snapshots outside the primary storage pool. • Enforce hard limits on who can access data and when access is permitted.
  6. Types of Ransomware Attackers may use one of several different approaches to extort digital currency from their victims: Scareware : This malware poses as security software or tech support. Ransomware victims may receive pop-up notifications saying malware has been discovered on their system. Security software that the user does not own would not have access to this information. Not responding to this will not do anything except lead to more pop-ups. Screen lockers : Also known simply as lockers, these are a type of ransomware designed to completely lock users out of their computers. Upon starting up the computer, a victim may see what looks to be an official government seal, leading the victim into believing they are the subject of an official inquiry. After being informed that unlicensed software or illegal web content has been found on the computer, the victim is given instructions on how to pay an electronic fine. However, official government organizations would not do this; they instead would go through proper legal channels and procedures. Encrypting ransomware : Otherwise known as data kidnapping attacks, these give the attacker access to and encrypt the victim's data and ask for a payment to unlock the files. Once this happens, there is no guarantee that the victim will get access to their data back -- even if they negotiate for it. The attacker may also encrypt files on infected devices and make money by selling a product that promises to help the victim unlock files and prevent future malware attacks. Doxware : With this malware, an attacker may threaten to publish victim data online if the victim does not pay a ransom. Master boot record ransomware : With this, the entire hard drive is encrypted, not just the user's personal files, making it impossible to access the operating system. Mobile ransomware : This ransomware affects mobile devices. An attacker can use mobile ransomware to steal data from a phone or lock it and require a ransom to return the data or unlock the device.
  7. How do ransomware attacks work ? - Ransomware kits on the deep web have enabled cybercriminals to purchase and use software tools to create ransomware with specific capabilities. They can then generate this malware for their own distribution, with ransoms paid to their bitcoin accounts. As with much of the rest of the information technology world, it is now possible for those with little or no technical background to order inexpensive ransomware as a service (RaaS) and launch attacks with minimal effort. - One of the more common methods of delivering ransomware attacks is through a phishing email. An attachment the victim thinks they can trust is added to an email as a link. Once the victim clicks on that link, the malware in the file begins to download. - Other more aggressive forms of ransomware will exploit security holes to infect a system, so they do not have to rely on tricking users. The malware can also be spread through chat messages, removable Universal Serial Bus (USB) drives or browser plugins. - Once the malware is in a system, it will begin encrypting the victim's data. It will then add an extension to the files, making them inaccessible. Once this is done, the files cannot be decrypted without a key known only by the attacker. The ransomware will then display a message to the victim, explaining that files are inaccessible and can only be accessed again upon paying a ransom to the attackers -- commonly in the form of bitcoin.
  8. What is ransomware ? - Ransomware is a subset of malware in which the data on a victim's computer is locked -- typically by encryption -- and payment is demanded before the ransomed data is decrypted and access is returned to the victim. The motive for ransomware attacks is usually monetary, and unlike other types of attacks, the victim is usually notified that an exploit has occurred and is given instructions for how to recover from the attack. Payment is often demanded in a virtual currency, such as bitcoin, so that the cybercriminal's identity is not known. - Ransomware malware can be spread through malicious attachments found in emails or in infected malicious software apps, infected external storage devices and compromised websites. Attacks have also used Remote Desktop Protocol and other approaches that do not rely on any form of user interaction.
  9. NAS maker QNAP continues to issue security alerts, and QNAP says ransomware called DeadBolt is looking for NAS servers exposed on the public internet. Earlier this month, QNAP issued an alert saying it had detected a large number of attacks of unknown origin, which sought to exploit vulnerabilities and weak passwords in devices exposed on the public Internet. QNAP did not mention whether the ransomware in the warning was related to the attack at the beginning of the month, but judging from the content of the two warnings, it should be the same batch of attacks. “DeadBolt has been widely targeting all NAS exposed to the Internet without any protection and encrypting users’ data for Bitcoin ransom,” the company said. “QNAP urges all QNAP NAS users to […] immediately update QTS to the latest available version.” QNAP said in the announcement that the ransomware called DeadBolt ransomware is looking for exposed NAS on the network, and then looking for potential vulnerabilities to try to launch an attack. The company said that the ransomware is not complicated and mainly relies on the vulnerabilities of the old QTS system, so it is very important for users to update the QTS system in a timely manner. It is worth noting that in the two warnings, QNAP strongly advised users not to expose their devices to the public Internet. However, for users, not being exposed to the public network means that they cannot connect to the public network, and it is very difficult and inconvenient to access the server content when going out. QNAP even suggested that users turn off the UPnP function of the router. The following are safety recommendations: Use the built-in security advisory function of the QNAP device to scan the potential risks of the device, including detecting whether the device is exposed to the public network and specific open ports. If the scanning shows that the system management service can be accessed from an external address then the device is at high risk and the user should follow the security advisor guidelines to disable public network access. Including disabling external address access, disabling exposed ports, turning off port forwarding or UPnP on the router, and DMZ to ensure that the internal network cannot be accessed from the outside. Of course, the result of this is that users will not be able to access QNAP devices through the external network. If you really need external network access, you can try other methods to strengthen security. Including but not limited to using multi-factor authentication, using high-strength passwords, non-repeating passwords, or using encrypted tunnels to connect to the intranet before using the intranet to access.
  10. In an unprecedented move, Russia's Federal Security Service (FSB), the country's principal security agency, on Friday disclosed that it arrested several members belonging to the notorious REvil ransomware gang and neutralized its operations. The surprise takedown, which it said was carried out at the request of the U.S. authorities, saw the law enforcement agency conduct raids at 25 addresses in the cities of Moscow, St. Petersburg, Moscow, Leningrad and Lipetsk regions that belonged to 14 suspected members of the organized cybercrime syndicate. "In order to implement the criminal plan, these persons developed malicious software, organized the theft of funds from the bank accounts of foreign citizens and their cashing, including through the purchase of expensive goods on the Internet," the FSB said in a statement. In addition, the FSB seized over 426 million rubles, including in cryptocurrency, $600,000, €500,000, as well as computer equipment, crypto wallets used to commit crimes, and 20 luxury cars that were purchased with money obtained by illicit means. One of the most active ransomware crews last year, REvil took responsibility for high-profile attacks against JBS and Kaseya, among a string of several others. The U.S. government told Reuters that one of the arrested individuals was also behind the ransomware attack on Colonial Pipeline in May 2021, once again confirming REvil's connections to a second collective called DarkSide. The group formally closed shop in October 2021 after the U.S. intervened to take its network of dark web servers offline. The next month, law enforcement authorities announced the arrest of seven individuals for their roles as affiliates of the REvil ransomware family, even as the U.S. charged a 22-year-old Ukrainian citizen linked to the ransomware gang for orchestrating the Kaseya ransomware attack. All those detained have been charged with "illegal circulation of means of payment," a criminal offense punishable by up to six years in prison. The suspects weren't named, but Reuters noted that a Moscow court identified two of the men as Roman Muromsky and Andrei Bessonov. The crackdown also comes as threat actors likely affiliated with Russian secret services crippled much of the Ukrainian government's public-facing digital infrastructure, in addition to defacing some of them with messages that alleged people's personal data had been made public and that the information stored in the servers was being destroyed. It remains to be what impact the arrests will have on the larger ransomware ecosystem, which has by and large continued to flourish despite a number of law enforcement actions, partly driven by Russia's willingness to look the other way when it comes to harboring cybercriminals in the country, effectively allowing the bad actors to operate with impunity. "While we are still looking to understand the true impact of these arrests, we applaud the Russian government for the actions it took today with regard to the REvil criminal ransomware group," Matt Olney, director of threat intelligence and interdiction at Cisco Talos, told The Hacker News. "It's important that criminal cyber actors and organizations not be allowed to operate with impunity. And so any result that leads to degrading of their capabilities is undoubtedly a good thing."
