![]() ![]() So, how do businesses protect themselves from these vamipric cyberattacks? The main defense is visibility. Brute Force: Operation Prowli, the fourth of the main cryptojacking campaigns, uses an arsenal of attack techniques like exploits and brute-forcing passwords and weak configurations. Taylor, lets attackers exchange scripts by hiding them within Taylor Swift photos.Ĥ. Hanako leaves a backdoor user named Hanako within compromised databases. Hex used numerous variations of Hex.exe within its code. It comes in three variants, each named after identifiable traits. Hidden Scripts: Hexmenwas discovered in data centers in China. All of this is done while leaving a backdoor, allowing Bondnet to enthrall any infected network.ģ. Bondnet is a very scary botnet created by infecting thousands of servers and conscripting them into one single botnet. Botnets: In 2017, GuardiCore discovered Bondnet. PhotoMiner infects websites hosted on FTP servers, making end users mine Monero (the favored cryptocurrency of hackers)Ģ. Worms: The first attack discovered by GuardiCore was a worm they named PhotoMiner. Each example shows a precedent in how different kinds of cryptomining campaigns behave.ġ. GuardiCore Labs has been studying cryptojacking campaigns since 2016, and have discovered four prominent examples of attacks on enterprise networks: PhotoMiner, Bondnet, Hexmen, and Operation Prowli. The attack is also harder to discover on an enterprise network as it can move alongside lateral traffic, a blind spot for most security teams, letting it go undetected for unprecedented amounts of time. The average user won’t even notice something is amiss before it’s too late, and new hardware or software is bought to keep up with the increased demands. The mining code will take over a regular and authentic system process, pretending to be benign. Once inside, the network is practically charmed by the malware. This attack is done by the injection of mining code into servers, often after an employee unwittingly invites the hackers into the network. Instead, hackers are now targeting telcos, ISPs, mid to large-sized enterprises, and even government agencies. Using personal computers as a de facto botnet isn’t exactly the most efficient way to mine for coins. ![]() According to a study published by AdGuard, over half a billion people have unwittingly mined coins for cryptojackers by visiting websites embedded with mining scripts. The most terrifying statistic about these parasitic pieces of software is how widespread they are. Cryptojacking is a malware that sinks its teeth into your system and covertly siphons off computing power and electricity to mine a cryptocurrency. As these cryptocurrencies exploded in popularity and profitability, so did cryptojacking. This trend coincides with the legitimization of cryptocurrencies like Bitcoin, Etherium, and the countless altcoins out there. ![]() 2018 has seen a 629% increase in cyrptojacking attacks, securing the malware’s position as the new threat on the block. Be careful about what kind of data you invite into your network. ![]()
