Those attacks used the Lightweight Directory Access Protocol (LDAP) resource call of Log4j to retrieve a malicious Java class file that modified existing, legitimate Java code, injecting a web shell into the VM Blast Secure Gateway service and thereby granting attackers remote access and code execution. Other attacks included those that installed web shells. In late December and January, VMWare’s Horizon servers with Log4Shell vulnerabilities came under Cobalt Strike attack, as flagged by researchers at Huntress. “Attempts to compromise Horizon servers are among the more targeted exploits of Log4Shell vulnerabilities because of their nature,” Sophos said.Įven those organizations that have applied the patches or workarounds may have been already compromised in other ways, given the backdoors and reverse-shell activity Sophos has tracked, the researchers cautioned. These servers have been important tools in organizations’ arsenals over the past few years, given that the pandemic triggered the necessity to provide work-from-home tools, the researchers pointed out.Īlthough VMware released patched versions of Horizon earlier this month – on March 8 – many organizations may not have been able to deploy the patched version or apply workarounds, if they even know that they’re vulnerable to begin with. In particular, those attacks have included ones targeting vulnerable VMware Horizon servers: a platform that serves up virtual desktops and apps across the hybrid cloud. In other words, some outfits don’t necessarily know if they’re vulnerable.

Log4Shell has been a nightmare for organizations to hunt down and remediate, given that the flaw affected hundreds of software products, “making it difficult for some organizations to assess their exposure,” noted Sophos researchers Gabor Szappanos and Sean Gallagher in Tuesday’s report. With millions of Log4j-targeted attacks clocking in per hour since the flaw’s discovery, within just a few weeks, there was a record-breaking peak of 925 cyberattacks per week per organization, globally, as Check Point Research (CPR) reported in early January. Sophos’s findings about VMware Horizon servers being besieged by threat actors leveraging the bug is in keeping with what’s been happening since then: In fact, cyberattacks increased 50 percent YoY in 2021, peaking in December, due to a frenzy of Log4j exploits. The Log4j flaw was discovered in December, vigorously attacked within hours of its discovery and subsequently dubbed Log4Shell. On Tuesday, Sophos reported that the remote code execution (RCE) Log4j vulnerability in the ubiquitous Java logging library is under active attack, “particularly among cryptocurrency mining bots.” Besides cryptominers, attackers are also prying open Log4Shell to deliver backdoors that Sophos believes are initial access brokers (IABs) that could lay the groundwork for later ransomware infections.

What researchers are calling a “horde” of miner bots and backdoors are using the Log4Shell bug to take over vulnerable VMware Horizon servers, with threat actors still actively waging some attacks. It infects the system through four crypto miners and three various backdoors.Researchers have found three backdoors and four miners in attacks exploiting the Log4Shell vulnerability, some of which are still ongoing. Recently, Sophos cybersecurity analysts said that the Log4Shell attacks are thriving in the unsecured VMware Horizon servers. However, several systems still remained outdated at that time.

Back in December, there was a patch to combat this dangerous threat. Based on its findings, it appeared that this exploit was staged by state-sponsored hackers wherein the center of the scheme is cryptocurrency mining and spreading bots and malware. Log4Shell Exploit Continues to Hit VMware Servers According to a report by ZDNET, Microsoft has previously dealt with Log4Shell vulnerability. The worst part is that the hackers can easily steal your personal information by using scripts in the process. Apart from that, they also uncovered that the attacks also involved the deployment of crypto miners and backdoors.

Cybersecurity experts recently discovered that the Log4Shell exploitation is happening, and the hackers are attacking the VMware Horizon servers.
