Ukraine’s CERT Warns of New Malware, CrescentImp
Ukraine’s CERT warns of CrescentImp malware targeting media organizations, including radio stations and news agencies. The malware, associated with the Sandworm group, uses the CVE-2022-30190 vulnerability in Microsoft's MSDT for infection, impacting 500 email addresses in the campaign.
Remote Code Execution Vulnerability found with Fastjson RCE
JFrog's research uncovers an RCE vulnerability in Fastjson, affecting 5000 Maven projects. The flaw bypasses AutoTypeCheck and requires specific conditions for exploitation. Attackers need to find a suitable "gadget" class within the Java application to exploit the vulnerability.
BlackCat Creates Site for Victims to Query for Stolen Data
The BlackCat/ALPHV ransomware gang has launched a site where employees and customers of victimized organizations can check if their data was stolen. This tactic was observed by Emisoft security analyst Brett Callow, with the latest attack targeting a hotel and spa in Oregon. The gang obtained 112GB of data, including sensitive employee information such as Social Security Numbers and birthdates, as well as guest names, arrival dates, and stay costs. Victims risk having their data exposed in search engine results.
HelloXD Ransomware And MicroBackdoor
Since November 2021, HelloXD ransomware has been observed by Palo Alto Unit42 conducting double extortion attacks without a data leak site, negotiating through TOX chat and onion-based messengers. The ransomware shares coding similarities with Babuk. The group uses MicroBackdoor to maintain a foothold, monitor progress, and execute commands. The developer, x4k, is a Russian-speaking threat actor involved in various cybercrime activities.
Cerber Ransomware Exploits Confluence Vulnerability
Sophos has tracked the exploitation of Confluence vulnerability CVE-2022-26134, discovering that the attack vector is shrinking with fewer vulnerable Confluence servers. Despite this, two exploit attempts were observed targeting Windows servers to deploy Cerber ransomware. Attackers ran curl and PowerShell commands, with the PowerShell command encoded to download and execute a payload in the %temp% folder. The attacks were mitigated successfully, with no evidence of data exfiltration or lateral movement.
Attackers Exploit Telerik UI to Deliver Cryptominer and Cobalt Strike
Sophos researchers have identified the reuse of tactics, techniques, and procedures (TTPs) by attackers exploiting the Telerik UI vulnerability CVE-2019-18935. The threat actors deliver Cobalt Strike beacons to disk, executing encoded PowerShell commands to download additional malware and establish persistence. The observed attack chain includes placing the Cobalt Strike DLL payload in the C:\Windows\Temp directory, downloading cryptominer XMRig, and using group policy objects and scheduled tasks for persistence.
