A previously known Windows-based ransomware strain known as IceFire has expanded its focus to target Linux enterprise networks belonging to several media and entertainment sector organizations across the world.

The intrusions entail the exploitation of a recently disclosed deserialization vulnerability in IBM Aspera Faspex file-sharing software (CVE-2022-47986, CVSS score: 9.8), according to cybersecurity company SentinelOne.
 
Threat actors are exploiting a critical vulnerability in an IBM file-exchange application in hacks that install ransomware on servers, security researchers have warned.

The IBM Aspera Faspex is a centralized file-exchange application that large organizations use to transfer large files or large volumes of files at very high speeds. Rather than relying on TCP-based technologies such as FTP to move files, Aspera uses IBM’s proprietary FASP—short for Fast, Adaptive, and Secure Protocol—to better utilize available network bandwidth. The product also provides fine-grained management that makes it easy for users to send files to a list of recipients in distribution lists or shared inboxes or workgroups, giving transfers a workflow that’s similar to email. In late January, IBM warned of a critical vulnerability in Aspera versions 4.4.2 Patch Level 1 and earlier and urged users to install an update to patch the flaw. Tracked as CVE-2022-47986, the vulnerability makes it possible for unauthenticated threat actors to remotely execute malicious code by sending specially crafted calls to an outdated programming interface. The ease of exploiting the vulnerability and the damage that could result earned CVE-2022-47986 a severity rating of 9.8 out of a possible 10.

On Tuesday, researchers from security firm Rapid7 said they recently responded to an incident in which a customer was breached using the vulnerability.
