Apple Security Advisory 11-19-2024-3

Building on its broad security portfolio, Microsoft's new exposure management is now available in the Microsoft Defender portal, with third-party-connectors on the way.

Source: Wavebreak Media ltd via Alamy Stock Photo

Microsoft is the latest big name to add continuous threat exposure management (CTEM) to its formidable security portfolio with the release of its new Microsoft Security Exposure Management offering. Microsoft made the announcement at its annual Microsoft Ignite conference this week.

Security experts describe CTEM, or proactive exposure management, as a programmatic and unified approach to detecting and mitigating threats. Gartner predicts that by 2026, organizations that embrace CTEM will see two-thirds fewer breaches.

Enterprise Strategy Group principal analyst Tyler Shields describes exposure management as the next iteration of vulnerability management.

"It's centered on the overlap of continuous asset discovery and management, threat and exposure analysis, and vulnerability discovery," Shields says. "If you can understand the assets you have, the state they are in, the vulnerabilities that exist, and the active threats against them, you are all prepared to secure your environment."

Microsoft initially introduced Security Exposure Management in March as a technical preview. It is now available in the Microsoft Defender portal, included with its E5 licenses, and as an option for various other Microsoft 365 licenses.

**Unified Views of Attack Surfaces**

With its entry, Microsoft seeks to enable defenders to prevent successful attacks by providing comprehensive and unified views of their organizations' broad attack surfaces, allowing them to take a more proactive approach to identifying and mitigating threats.

"Exposure management is critical for enabling teams to understand the posture of the organization, and it helps security teams see all the potential attack paths to critical assets as if they were looking through it, through the eyes of the attacker," said Vasu Jakkal, Microsoft's corporate VP for compliance, identity management, during the opening session at Ignite, which took place in Chicago.

The tooling is designed to identify attack paths and evaluate vulnerabilities in the context of an organization's critical assets in a more proactive and expansive manner than traditional vulnerability and threat detection offerings. Security Exposure Management uses Microsoft's new exposure graph APIs to identify attack paths and evaluate vulnerabilities in the context of critical assets.

Analysts say Microsoft's entry is poised to reshape the competitive environment of exposure management solutions offered by Cisco/Splunk, CrowdStrike, Palo Alto Networks Rapid7, Tenable, Trend Micro, and Wiz, as well as various others that provide more specialized capabilities.

"Exposure management is becoming an incredibly competitive market, and Microsoft is demonstrating that it wants to be a leader in this space," says Omdia principal analyst Andrew Braunberg.

Adds Forrester senior analyst Erik Nost, since Microsoft is initially allowing access to exposure management through a variety of licensing options, customers will have widespread access to insights.

"The data Microsoft possesses on existing customer environments without needing to ingest third-party data is the biggest opportunity for Microsoft to set it apart from competitors," Nost says. "Microsoft is building a platform that integrates a very broad set of security posture management telemetry."

**Building an Ecosystem of External Connections**

While the initial release is available and included with various Microsoft 365 and Microsoft Defender licenses and will ingest telemetry from those offerings, Microsoft announced it will enable integration with competing external third-party tools, including Qualys, Rapid7, Tenable, and ServiceNow's CMDB.

Microsoft released public preview versions of its third-party connectors, slated to become generally available next quarter.

Unlike Microsoft telemetry, which customers can ingest at no additional cost, they will incur charges to gather data from external sources, said Microsoft product director Brjann Brekkan, during a session on security exposure management at Ignite.

"We don't own that data," Brekkan explained. "We need to charge a little bit of cost to bring that third-party signal in, to attach those new data points from those services as well. But this is there for you to unify your data."

Security Exposure Management collects data through these connectors and normalizes it through its exposure graph, which maps relationships and exposes new attack paths. In a blog post, Brekkan said this provides "comprehensive attack surface visibility."

Microsoft exposure management also provides insights on the most critical assets, Internet exposure, and context related to business applications incorporated from the connected tools. Customers can view the integrated data, which can be visualized through the Attack Map tool or analyzed using advanced hunting queries via KQL (Kusto Query Language), Microsoft's Azure-based tool designed to identify anomalies in large data sets.

The offering now consists of three primary tools:

*   Attack Surface Management: Defenders have access to continuous views of their organization's attack surface. Notably, the tool identifies the most critical assets and those that are the prime targets of attackers
    
*   Attack Path Analysis: Security teams can visualize and prioritize high-risk attack paths, particularly those targeting those critical assets
    
*   Unified Exposure Insights: Administrators can view their organization's threat exposure, allowing them to prioritize risks and tie remediation priorities with business imperatives.
    

Omdia's Braunberg says it remains to be seen how many customers will build their exposure management strategies around Microsoft's offering, it is likely many will evaluate it, especially considering its potentially low cost.

"As per Microsoft's usual playbook, exposure management is attractive because it pulls together a lot of existing Microsoft functionality into an integrated solution with small incremental costs," he says.

Microsoft Highlights Security Exposure Management at Ignite

In a first, Russia's APT28 hacking group appears to have remotely breached the Wi-Fi of an espionage target by hijacking a laptop in another building across the street.

For determined hackers, sitting in a car outside a target's building and using radio equipment to breach its Wi-Fi network has long been an effective but risky technique. These risks became all too clear when spies working for Russia's GRU military intelligence agency were caught red-handed on a city street in the Netherlands in 2018 using an antenna hidden in their car's trunk to try to hack into the Wi-Fi of the Organization for the Prohibition of Chemical Weapons.

Since that incident, however, that same unit of Russian military hackers appears to have developed a new and far safer Wi-Fi hacking technique: Instead of venturing into radio range of their target, they found another vulnerable network in a building across the street, remotely hacked into a laptop in that neighboring building, and used that computer's antenna to break into the Wi-Fi network of their intended victim—a radio-hacking trick that never even required leaving Russian soil.

At the Cyberwarcon security conference in Arlington, Virginia, today, cybersecurity researcher Steven Adair will reveal how his firm, Volexity, discovered that unprecedented Wi-Fi hacking technique—what the firm is calling a “nearest neighbor attack"—while investigating a network breach targeting a customer in Washington, DC, in 2022. Volexity, which declined to name its DC customer, has since tied the breach to the Russian hacker group known as Fancy Bear, APT28, or Unit 26165. Part of Russia's GRU military intelligence agency, the group has been involved in notorious cases ranging from the breach of the Democratic National Committee in 2016 to the botched Wi-Fi hacking operation in which four of its members were arrested in the Netherlands in 2018.

In this newly revealed case from early 2022, Volexity ultimately discovered not only that the Russian hackers had jumped to the target network via Wi-Fi from a different compromised network across the street, but also that this prior breach had _also_ potentially been carried out over Wi-Fi from yet another network in the same building—a kind of “daisy-chaining” of network breaches via Wi-Fi, as Adair describes it.

“This is the first case we’ve worked where you have an attacker that’s extremely far away and essentially broke into other organizations in the US in physical proximity to the intended target, then pivoted over Wi-Fi to get into the target network across the street,” says Adair. “That’s a really interesting attack vector that we haven’t seen before.”

Based on the hackers' targeting of individuals within their customer's network, Adair says that the GRU hackers appear to have been seeking intelligence about Ukraine. It's no coincidence, he says, that the daisy-chained Wi-Fi-based intrusion was carried out in the months just before and after Russia's initial full-scale invasion of Ukraine in February 2022.

Adair argues, though, that the case should serve as a broader warning about cybersecurity threats to Wi-Fi for high-value targets—and not just from the usual suspects loitering in the parking lot or the lobby. “Now we know that a motivated nation-state is doing this and has done it,” says Adair, “It puts on the radar that Wi-Fi security has to be ramped up a good bit.” He suggests organizations that might be the target of similar remote Wi-Fi attacks consider limiting the range of their Wi-Fi, changing the network's name to make it less obvious to potential intruders, or introducing other authentication security measures to limit access to employees.

Adair says that Volexity first began investigating the breach of its DC customer's network in the first months of 2022, when the company saw signs of repeated intrusions into the customer's systems by hackers who had carefully covered their tracks. Volexity's analysts eventually traced the compromise to a hijacked user's account connecting to a Wi-Fi access point in a far end of the building, in a conference room with external-facing windows. Adair says he personally scoured the area looking for the source of that connection. “I went there to physically run down what it could be. We looked at smart TVs, looked for devices in closets. Is someone in the parking lot? Is it a printer?” he says. “We came up dry.”

Only after the next intrusion, when Volexity managed to get more complete logs of the hackers' traffic, did its analysts solve the mystery: The company found that the hijacked machine which the hackers were using to dig around in its customer's systems was leaking the name of the domain on which it was hosted—in fact, the name of another organization just across the road. “At that point, it was 100 percent clear where it was coming from,” Adair says. “It's not a car in the street. It's the building next door.”

With the cooperation of that neighbor, Volexity investigated that second organization's network and found that a certain laptop was the source of the street-jumping Wi-Fi intrusion. The hackers had penetrated that device, which was plugged into a dock connected to the local network via Ethernet, and then switched on its Wi-Fi, allowing it to act as a radio-based relay into the target network. Volexity found that, to break into that target's Wi-Fi, the hackers had used credentials they'd somehow obtained online but had apparently been unable to exploit elsewhere, likely due to two-factor authentication.

Volexity eventually tracked the hackers on that second network to two possible points of intrusion. The hackers appeared to have compromised a VPN appliance owned by the other organization. But they had also broken into the organization's Wi-Fi from _another_ network's devices in the same building, suggesting that the hackers may have daisy-chained as many as three networks via Wi-Fi to reach their final target. “Who knows how many devices or networks they compromised and were doing this on,” says Adair.

In fact, even after Volexity evicted the hackers from their customer's network, the hackers tried again that spring to break in via Wi-Fi, this time attempting to access resources that were shared on the guest Wi-Fi network. “These guys were super persistent,” says Adair. He says that Volexity was able to detect this next breach attempt, however, and quickly lock out the intruders.

Volexity had presumed early on in its investigation that the hackers were Russian in origin due to their targeting of individual staffers at the customer organization focused on Ukraine. Then in April, fully two years after the original intrusion, Microsoft warned of a vulnerability in Windows' print spooler that had been used by Russia's APT28 hacker group—Microsoft refers to the group as Forest Blizzard—to gain administrative privileges on target machines. Remnants left behind on the very first computer Volexity had analyzed in the Wi-Fi-based breach of its customer exactly matched that technique. “It was an exact one-to-one match,” Adair says.

The notion that APT28 would be behind the daisy-chained Wi-Fi hacking makes sense, says John Hultquist, the founder of Cyberwarcon who also leads threat intelligence at Google-owned cybersecurity firm Mandiant and has long tracked the GRU hackers. He sees the technique Volexity uncovered as the natural evolution of APT28's “close-access” hacking methods, in which the GRU has sent small traveling teams in person to hack into target networks via Wi-Fi if other methods failed.

“This is essentially a close-access op like they’ve done in the past, but without the close access,” Hultquist says.

The switch to hacking via Wi-Fi from a remotely compromised device rather than physically placing a spy nearby represents a logical next step following the GRU's operational security disaster in 2018, when its hackers were caught in a car in The Hague attempting to hack the Organization for the Prohibition of Chemical Weapons in response to the OPCW's investigation of the attempted assassination of GRU defector Sergei Skripal. In that incident, the APT28 team was arrested and their devices were seized, revealing their travel around the world from Brazil to Malaysia to carry out similar close-access attacks.

“If a target is important enough, they’re willing to send people in person. But you don’t have to do that if you can come up with an alternative like what we’re seeing here,” Hultquist says. “This is potentially a major improvement for those operations, and it’s something we’ll probably see more of—if we haven’t already.”
