Poorly managed Linux SSH servers are getting compromised by unknown attackers and instructed to engage in DDoS attacks while simultaneously mining cryptocurrency in the background. "The source code of Tsunami is publicly available so it is used by a multitude of threat actors. Among its various uses, it is mostly used in attacks against IoT devices. Of course, it is also consistently used to target Linux servers," researchers with AhnLab's Security Emergency response Center explained.
Attacks on commerce are booming, according to a new study by security firm Akamai. Bots raining on retail drive flood in commerce attacks.
Toyota Motor Corporation has discovered two additional misconfigured cloud services that leaked car owners' personal information for over seven years. This finding came after the Japanese carmaker conducted a thorough investigation on all cloud environments managed by Toyota Connected Corporation after previously discovering a misconfigured server that exposed the location data of over 2 million customers for ten years.
If you're running an Apache NiFi instance exposed on the internet and you have not secured access to it, the underlying host may already be covertly cryptomining on someone else's behalf. "Routers make bad cryptomining servers. Cryptomining may be what they end up doing if the lateral movement doesn't get them anywhere."
The notorious North Korean state-backed hackers, known as the Lazarus Group, are now targeting vulnerable Windows Internet Information Services web servers to gain initial access to corporate networks. The latest tactic of targeting Windows IIS servers was discovered by South Korean researchers at the AhnLab Security Emergency Response Center.
Emby says it remotely shut down an undisclosed number of user-hosted media server instances that were recently hacked by exploiting a previously known vulnerability and an insecure admin account configuration. To trick the servers into granting them access and gain admin servers to the vulnerable servers even though they were attempting to log in from outside the LAN, the threat actors exploited a flaw described by Emby as a "Proxy header vulnerability," known since at least February 2020 and recently patched in the beta channel.
A new PowerShell-based malware dubbed PowerExchange was used in attacks linked to APT34 Iranian state hackers to backdoor on-premise Microsoft Exchange servers. Notably, the malware communicates with its command-and-control server via emails sent using the Exchange Web Services API, sending stolen info and receiving base64-encoded commands through text attachments to emails with the "Update Microsoft Edge" subject.
An updated version of the commodity malware called Legion comes with expanded features to compromise SSH servers and Amazon Web Services credentials associated with DynamoDB and CloudWatch. "This recent update demonstrates a widening of scope, with new capabilities such the ability to compromise SSH servers and retrieve additional AWS-specific credentials from Laravel web applications," Cado Labs researcher Matt Muir said in a report shared with The Hacker News.
The infamous Lazarus Group actor has been targeting vulnerable versions of Microsoft Internet Information Services servers as an initial breach route to deploy malware on targeted systems. The findings come from the AhnLab Security Emergency response Center, which detailed the advanced persistent threat's continued abuse of DLL side-loading techniques to deploy malware.
The Irish Data Protection Commission has announced a $1.3 billion fine on Facebook after claiming that the company violated Article 46(1) of the GDPR. More specifically, it was found that Facebook transferred data of EU-based users of the platform to the United States, where data protection regulations vary per state and have been deemed inadequate to protect the rights of EU data subjects. As a result of the infringement, the DPC imposed a record €1.2 billion fine on Facebook's parent company, Meta Ireland, and requested that all data transfers that violate the GDPR be suspended within five months of the decision.
