Powerful Spyware Exploits Enable a New String of 'Watering Hole' Attacks

In caller years, elite commercialized spyware vendors similar Intellexa and NSO Group person developed an array of almighty hacking tools that exploit uncommon and unpatched “zero-day" bundle vulnerabilities to compromise unfortunate devices. And increasingly, governments around the world person emerged arsenic the prime customers for these tools, compromising the smartphones of absorption leaders, journalists, activists, lawyers, and others. On Thursday, though, Google's Threat Analysis Group is publishing findings astir a bid of caller hacking campaigns—seemingly carried retired by Russia's notorious APT 29 Cozy Bear gang—that incorporated exploits precise akin to ones developed by Intellexa and NSO Group into ongoing espionage activity.

Between November 2023 and July 2024, the attackers compromised Mongolian authorities websites and utilized the entree to behaviour “watering hole” attacks, successful which anyone with a susceptible instrumentality who loads a compromised website gets hacked. The attackers acceptable up the malicious infrastructure to usage exploits that “were identical oregon strikingly akin to exploits antecedently utilized by commercialized surveillance vendors Intellexa and NSO Group,” Google TAG wrote connected Thursday. The researchers accidental they “assess with mean confidence” that the campaigns were carried retired by APT 29.

These spyware-esque hacking tools exploited vulnerabilities successful Apple's iOS and Google's Android that had mostly already been patched. Originally, they were deployed by the spyware vendors arsenic unpatched, zero-day exploits; but successful this iteration, the suspected Russian hackers were utilizing them to people devices that hadn't been updated with these fixes.

“While we are uncertain however suspected APT29 actors acquired these exploits, our probe underscores the grade to which exploits archetypal developed by the commercialized surveillance manufacture are proliferated to unsafe menace actors,” the TAG researchers wrote. “Moreover, watering spread attacks stay a menace wherever blase exploits tin beryllium utilized to people those that sojourn sites regularly, including connected mobile devices. Watering holes tin inactive beryllium an effectual avenue for … wide targeting a colonisation that mightiness inactive tally unpatched browsers.”

It is imaginable that the hackers purchased and adapted the spyware exploits oregon that they stole them oregon acquired them done a leak. It is besides imaginable that the hackers were inspired by commercialized exploits and reverse engineered them by examining infected unfortunate devices.

Between November 2023 and February 2024, the hackers utilized an iOS and Safari exploit that was technically identical to an offering Intellexa archetypal debuted a mates of months earlier arsenic an unpatched zero-day successful September 2023. In July 2024, the hackers besides utilized a Chrome exploit adapted from an NSO Group instrumentality that archetypal appeared successful May 2024. This second hacking instrumentality was utilized successful operation with an exploit that had beardown similarities to 1 Intellexa debuted backmost successful September 2021.

When attackers exploit vulnerabilities that person already been patched, the enactment is known arsenic “n-day exploitation,” due to the fact that the vulnerability inactive exists and tin beryllium abused successful unpatched devices arsenic clip passes. The suspected Russian hackers incorporated the commercialized spyware adjacent tools, but constructed their wide campaigns—including malware transportation and enactment connected compromised devices—differently than the emblematic commercialized spyware lawsuit would. This indicates a level of fluency and method proficiency diagnostic of an established and well-resourced state-backed hacking group.

“In each iteration of the watering spread campaigns, the attackers utilized exploits that were identical oregon strikingly akin to exploits from [commercial surveillance vendors], Intellexa and NSO Group,” TAG wrote. “We bash not cognize however the attackers acquired these exploits. What is wide is that APT actors are utilizing n-day exploits that were primitively utilized arsenic 0-days by CSVs.”
