What is the premium socks proxy list?The Premium Proxy list doesn't have a fixed number of proxies.Instead, it is updated every minute to ensure it is 90% working and anonymous.It is best for the users who want to get working socks proxies quickly, without testing a big list.How do you update the proxy lists?We update the normal socks proxy lists every hour and update the premium list every minute.On update, we add new working socks proxies to the lists and removing dead proxies from them.The working proxies remain on the lists.What is the type of your proxies??Our proxies are public socks proxy which we collect from the internet.They are unstable but very cheap, considering a private proxy charges $3/month.Our proxies are suitable for the users who need a lot of IP addresses and use each one for only a while.What is the proxy anonymity?There are 3 anonymous levels of HTTP proxies.By contrast, all socks proxies are highly anonymous.What is HTTPS / SSL proxy?Secure websites whose url starts with https:// instead of http:// (ex.

) use the encrypted (SSL/HTTPS) connections between its web server and the visitors.Some HTTP proxies only support ordinary HTTP sites and can't surf HTTPS sites.By contrast, all the socks proxies support HTTPS websites.Must I buy your software to get the proxies?No.You can use the free version of our software to download the proxy lists you bought.You can also use the API URL to get proxy lists Can I buy only US proxy or Europe proxy?No.We don't filter the socks proxies by country.However, you can sort the proxy list by country after download it.Are the proxies exclusive to me?No.They are not exclusive.We provide the same socks proxies to other users.Can I get completely different proxies every day?No.The working socks proxies remain on our proxy lists.You will get some same proxies every day.Can I get more proxies if I buy two lists?No, you will get the same socks proxies.Cisco Talos is currently observing a widespread campaign leveraging the Samas/Samsam/MSIL.B/C ransomware variant.Unlike most ransomware, SamSam is not launched via user focused attack vectors, such as phishing campaigns and exploit kits.

This particular family seems to be distributed via compromising servers and using them as a foothold to move laterally through the network to compromise additional machines which are then held for ransom.A particular focus appears to have been placed on the healthcare industry.Adversaries have been seen leveraging JexBoss, an open source tool for testing and exploiting JBoss application servers, to gain a foothold in the network.Once they have access to the network they proceed to encrypt multiple Windows systems using SamSam.Technical Details Upon compromising the system the sample will launch a samsam.exe process which begins the process of encrypting files on the system.SamSam encrypts various file types (see Appendix A) with Rijndael and then encrypts that key with RSA-2048 bit encryption.This makes the files unrecoverable unless the author made a mistake in the implementation of the encryption algorithms.The adversaries behind this ransomware variant did not go to any length to disguise or cover up the ransomware activity on the system.

The samples Talos obtained are not packed and do not contain anti-debugging features.One interesting note regarding the samples Talos has observed is that the malware will abort the encryption routine if the system is running a version of Microsoft Windows prior to Vista.ethereum price of gasThis is likely done for compatibility reasons.ethereum pc walletOnce installed on a machine there is no beaconing or C2 activity.bitcoin black swanThe ransomware is effectively self sufficient.raspberry pi 2 bitcoin miningBelow is an example of the communication between a victim and the adversaries.bitcoin escrow explained

Notice in this instance, the victim initially paid for one PC and followed up by paying for all affected PCs.Tools There were a couple of open source tools that were seen being leveraged by the adversaries.bitcoin merchants londonThe first is JexBoss, which is a testing and exploitation framework for JBoss application servers.bitcoin kosovoThis was being used as an initial infection vector to gain a foothold in the network to spread the ransomware.bitcoin r7The second is a component of REGeorg, tunnel.jsp.bitcoin hashrate poolsREGeorg is an open source framework to create socks proxies for communication.The file found in the samples is an unmodified version of the tunnel.jsp file that is being hosted by REGeorg (b963b8b8c5ca14c792d2d3c8df31ee058de67108350a66a65e811fd00c9a340c).

Payment Evolution As we have monitored this activity, we have started to see changes in the amount and types of payment options available to victims.Initially, we saw a payment option of 1 bitcoin for each PC that has been infected.Later we saw the price for a single system has been raised to 1.5 bitcoin.It is likely the malware author is trying to see how much people will pay for their files.They even added an option for bulk decryption of 22 bitcoin to decrypt all infected systems.Below is an example of this evolution.Others have also seen samples that have increased the payment amount to 1.7 bitcoin per PC.During our investigation we found multiple different bitcoin wallets being presented to users, some had 0 bitcoins associated with them others had significant amounts.The total amount of bitcoin in these wallets was at least ~275 which equates to approximately $115,000 USD.Below is a screen capture showing some of the obfuscated wallets.They have been obfuscated so that we can continue to monitor their activity.

Adversaries are exploiting known vulnerabilities in unpatched JBoss servers before installing a web shell, identifying further network connected systems, and installing SamSam ransomware to encrypt files on these devices.Ransomware continues to persist as a successful cyber crime business model.This technique is proving to be a profitable affair for criminals and will continue to be a threat to the internet at large until a more profitable technique is discovered.Protection against such threats is best achieved using a multi-tier defense architecture to ensure potential threats are scanned multiple times.However, one of the most effective ways to protect yourself is by simply backing up valuable files.Victims often find that at the moment when backups are most needed, they are either non-existent or incomplete.These lapses provide the revenue stream that is currently fueling the development of ransomware.Coverage The following Snort rules and ClamAV signatures address this threat.Please note that additional rules may be released at a future date and current rules are subject to change pending additional vulnerability information.
