CISA Warns of Active Attacks Exploiting Fortra MFT, TerraMaster NAS, and Intel Driver Flaws

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday additional 3 flaws to its Regarded Exploited Vulnerabilities (KEV) catalog, citing proof of energetic abuse in the wild.

Integrated among the 3 is CVE-2022-24990, a bug impacting TerraMaster network-hooked up storage (TNAS) units that could lead to unauthenticated remote code execution with the best privileges.

Facts about the flaw have been disclosed by Ethiopian cyber security investigate company Octagon Networks in March 2022.

The vulnerability, according to a joint advisory introduced by U.S. and South Korean authorities authorities, is said to have been weaponized by North Korean country-condition hackers to strike health care and critical infrastructure entities with ransomware.

The next shortcoming to be included to KEV catalog is CVE-2015-2291, an unspecified flaw in the Intel ethernet diagnostics driver for Windows (IQVW32.sys and IQVW64.sys) that could throw an impacted unit into a denial-of-service condition.

The exploitation of CVE-2015-2291 in the wild was disclosed by CrowdStrike past month, detailing a Scattered Spider (aka Roasted 0ktapus or UNC3944) attack that entailed an attempt to plant a legitimately signed but destructive version of the vulnerable driver making use of a tactic known as Bring Your Possess Susceptible Driver (BYOVD).

The objective, the cybersecurity firm said, was to bypass endpoint security software installed on the compromised host. The attack was finally unsuccessful.

The advancement underscores the growing adoption of the system by various threat actors, specifically BlackByte, Earth Longzhi, Lazarus Team, and OldGremlin, to ability their intrusions with elevated privileges.

Last of all, CISA has also extra a remote code injection found out in Fortra’s GoAnywhere MFT managed file transfer software (CVE-2023-0669) to the KEV catalog. Even though patches for the flaw have been released lately, the exploitation has been linked to a cybercrime group affiliated with a ransomware procedure.

Huntress, in an examination printed previously this 7 days, reported it observed the infection chain top to the deployment of TrueBot, a Windows malware attributed to a menace actor recognised as Silence and which shares connections with Evil Corp, a Russian cybercrime crew that displays tactical overlaps with TA505.

With TA505 facilitating the deployment of Clop ransomware in the previous, it’s becoming suspected that the attacks are a precursor to deploying file-locking malware on focused devices.

Also, security site Bleeping Computer described that the Clop ransomware crew achieved out to the publication and claimed to have exploited the flaw to steal info saved in the compromised servers from over 130 providers.

Federal Civilian Executive Branch (FCEB) agencies are expected to apply the fixes by March 3, 2023, to safe the networks from lively threats.
