With a score of 10/10 on the CVSSv3 severity scale, Log4Shell opens up hundreds of millions of devices to exploitation, cybersecurity experts have warned.Įarlier in August, the U.S. Among the companies whose servers may be vulnerable to Log4Shell attacks are Apple, Amazon, Twitter, Cloudflare, Steam, Tencent, and Baidu. Open-source projects like Redis, ElasticSearch, Elastic Logstash, and the NSA’s Ghidra use it to some extent. Log4j is present in almost all major Java-based enterprise apps and servers. Microsoft also published indicators of compromise allowing companies to investigate whether they exist in their systems. SysAid rolled out Log4j patches for its products in January, a month after a bug was discovered by an employee of the Chinese tech giant Alibaba.

Microsoft urged organizations using SysAid to apply security patches and update affected products and services.

Image: MicrosoftĪccording to Microsoft, the hackers stole user credentials by leveraging the open-source application Mimikatz. They also added malware to startup folders to ensure access even if the victim rebooted their system. The hackers then added a new user and elevated its privilege to a local administrator. The group used Log4j flaws to gain initial access to unpatched SysAid systems and dropped an infected script, a web shell, to run malicious commands. Looking for an alternative, Iranian hackers have turned to SysAid, another attractive target as it is used by numerous organizations in Israel, according to Microsoft. MuddyWater, for instance, used flaws in Log4j to exploit vulnerabilities in VMware apps, which were eventually patched. MuddyWater’s new attack, detected by Microsoft in late July, is another example of state-sponsored operations exploiting Log4Shell, a vulnerability in the Java library Log4j used to add logging capabilities to web and desktop applications.Įarlier in December, Microsoft discovered that nation-state groups from China, Iran, North Korea, and Turkey were abusing Log4Shell to gain access to targeted networks. In December, the group targeted telecommunication and IT service providers in the Middle East and Asia. Cyber Command said earlier this year that the group is affiliated with the Iranian Ministry of Intelligence and Security. The threat actor, which is also known as Mercury, has targeted vulnerabilities in SysAid, a popular IT management software used by many Israeli organizations, according to a report published by Microsoft on Thursday. Iranian hacker group MuddyWater, allegedly linked to the country’s state intelligence service, continues to exploit the Log4j vulnerability to gain access to corporate networks in Israel amid an ongoing proxy war between the two countries, according to new research.
