A cybercrime group tracked as Scattered Spider has been noticed exploiting an previous vulnerability in an Intel Ethernet diagnostics driver for Home windows in latest assaults on telecom and BPO corporations.

Additionally tracked as Roasted 0ktapus and UNC3944, the menace actor has been concentrating on telecom and enterprise course of outsourcing (BPO) corporations since June 2022, to realize entry to cell service networks.

Relentless in assaults, the menace actor was seen utilizing phishing and social engineering to acquire victims’ credentials and one-time passwords (OTPs), and deploying digital non-public community (VPN) and distant monitoring and administration (RMM) instruments put up compromise, CrowdStrike mentioned in December 2022.

Now, the cybersecurity agency studies that, over the previous a number of weeks, Scattered Spider has tried to deploy a malicious kernel driver by exploiting CVE-2015-2291, an Intel Ethernet diagnostics driver for Home windows flaw resulting in arbitrary code execution with kernel privileges.

“This vulnerability has been utilized by adversaries for a number of years to deploy malicious drivers into the Home windows kernel. This method is named ‘Deliver Your Personal Susceptible Driver’ (BYOVD) and is a tactic that has endured as a consequence of a spot in Home windows safety,” CrowdStrike notes.

Since Home windows Vista, Microsoft has blocked unsigned kernel-mode drivers from operating, however BYOVD permits attackers to bypass the safety and set up a legitimately signed however malicious driver. Publicly out there instruments can be utilized to map unsigned drivers into reminiscence.

Microsoft introduced that drivers with identified safety vulnerabilities could be blocked in Home windows 10, which additionally blocks kernel drivers that aren’t signed by Microsoft itself. Nevertheless, studies have proven that menace actors stay profitable in bypassing Redmond’s protections.

Scattered Spider, CrowdStrike explains, was noticed trying to load a malicious driver to bypass the safety protections supplied by a number of safety corporations, together with Microsoft, Palo Alto Networks, SentinelOne, and CrowdStrike.

The recognized iterations of the malicious driver are signed with stolen certificates and a self-signed take a look at certificates (this pattern is loaded utilizing BYOVD methods).

To stop the endpoint safety merchandise from blocking the malicious exercise, the motive force iterates by means of the loaded kernel modules for the safety software program’s element and patches it in reminiscence.

Organizations are suggested to scan their methods for the focused Intel driver and ensure that it has been patched towards CVE-2015-2291. They need to patch methods in a well timed method towards all identified vulnerabilities and may use an endpoint safety resolution on all of them.

“Whereas the outlined exercise seems to focus on particular industries, organizations of every type ought to apply the teachings realized to harden defenses towards such threats,” CrowdStrike concludes.
