Increased ProxyShellMiner activity observed We recently observed a ping spike in one of our IPS coinminer signatures. Upon further analysis, we found that the behavior is associated with ProxyShellMiner. It has been observed that the miner is delivered after attackers have successfully infiltrated into an organization's network by exploiting ProxyShell vulnerabilities CVE-2021-34473 and CVE-2021-34523 in Windows Exchange servers. ProxyShellMiner uses a technique called “process hollowing” to inject the miner into installed browsers on the compromised system and to start the coin-mining process. ProxyShellMiner can cause service outage, degrade server performance and disrupt business networks. Once the attackers have gained access to the network, they can perform additional malicious actions such as backdoor deployment or remote code execution. Symantec's network protection technology, Intrusion Prevention System (IPS) blocks this coin mining activity to prevent damage to the system. IPS also blocks the exploitation attempts for the ProxyShell vulnerabilities.

Is Haron ransomware a knockoff of Avaddon ransomware or a rebranding? Haron ransomware, first discovered in July 2021, has been seen using a ransom note and leak site similar to those used by Avaddon ransomware. While both are using Thanos ransomware code, Haron is using a version written in C#, while Avaddon was last seen using a C++ version. Haron is using a near duplicate of the leak site, a publicly available version of Thanos and insecure authentication. This indicates that they are likely not a rebranding of Avaddon, who are known to be more sophisticated and write their own ransomware code.

Israel-Hamas conflict typo-squatted On the weekend of October 7th and 8th, dramatic events unfolded in Israel leading to a major conflict with Hamas, a Palestinian political and militant organization. Over the past two days, Symantec has observed more than 170 newly-registered domains that appear to be related to donations, politics, and information surrounding the conflict, which some are referring to as war. While not all observed domains are malicious or shady, Symantec flagged suspicious ones and continues to monitor for malicious activities. During major incidents, especially those which garner widespread attention like wars and other crises, there's often a surge in Internet activity with people searching for information related to the event. Cybercriminals take advantage of this by creating typo-squatting domains. These domains have names similar to legitimate websites or events but contain slight misspellings or variations. When users make typing errors or misspellings while searching for information on the event, they might end up on these malicious sites instead of the intended ones. This tactic allows cybercriminals to engage in various nefarious activities such as spreading misinformation, conducting phishing attacks, donation scam or distributing malware. Users may be more vulnerable during these times due to heightened emotions and a sense of urgency to get the latest information. Symantec protects you from this threat, identified by the following: Web-based Observed domains/IPs are covered under security categories in all WebPulse enabled products
