CVE-2022-45673: VulnerabilityProjectRecords/fromSysToolRestoreSet.md at main · iceyjchen/VulnerabilityProjectRecords

By Habiba Rashid
A Barcelona-based company, a spyware vendor named Variston IT, is exploiting flaws under the guise of a custom cybersecurity solutions provider.
This is a post from HackRead.com Read the original post: Spyware Vendor Variston Exploited Chrome, Firefox and Windows 0-days

On 30th November, Google’s Threat Analysis Group (TAG) reported that a Barcelona-based company, actually a spyware vendor, named Variston IT has been exploiting n-day vulnerabilities in Chrome, Firefox, and **Microsoft Defender** under the guise of a custom cybersecurity solutions provider. 

In their detailed technical report, TAG explained that Variston IT had been using their exploitation framework called Heliconia to install spyware on the targeted devices. The researchers at Google received an anonymous submission to Chrome’s bug reporting program which brought to their attention the exploitation framework.

Heliconia actually contains three separate exploitation frameworks. One of them is used to compromise the Chrome renderer bug so that it can escape the walls of the app’s sandbox and run malware on the operating system.

Another one is used to deploy **malicious PDF documents** containing an exploit for Windows Defender (a built-in antivirus engine in the newer versions of Windows).  The last framework is for compromising Windows and Linux machines by using a set of Firefox exploits. 

A manifest file in the source code provides a product description (Image: Google)

In its **report**, the tech giant observed that the Heliconia exploit is successful against Firefox versions 64 to 68, which suggests that it was created and used as early as December 2018 when Firefox 64 first came out.

Google, Microsoft, and Mozilla fixed the vulnerabilities in 2021 and early 2022. They further stated that, although they had not detected active exploitation, it is likely that the vulnerabilities had been exploited before they could be fixed.

1.  **Google cracks down on sites with ties to hack-for-hire groups**
2.  **Israeli Spyware Vendor Use Chrome 0day to Target Journalists**
3.  **ISPs Helping Attackers Install Hermit Spyware on Smartphones**
4.  **Malware vendor returns with yet another nasty Android malware**
5.  **European Spyware Vendor Offer Android and iOS Device Exploits**

According to Google, **commercial spyware vendors** put advanced surveillance capabilities in the hands of governments who can then use them to spy on journalists, human rights activists, political opposition, and dissidents.

Therefore, there needs to be more transparency to ensure that companies adhere to their stated ethical standards in whom they make transactions with and whom they target with their products.

It is advised that users keep their Chrome and other software up-to-date with the security patches to ensure full protection against Heliconia.

Spyware Vendor Variston Exploited Chrome, Firefox and Windows 0-days

A Barcelona-based surveillanceware vendor named Variston IT is said to have surreptitiously planted spyware on targeted devices by exploiting several zero-day flaws in Google Chrome, Mozilla Firefox, and Windows, some of which date back to December 2018.

"Their Heliconia framework exploits n-day vulnerabilities in Chrome, Firefox, and Microsoft Defender, and provides all the tools necessary to deploy a payload to a target device," Google Threat Analysis Group (TAG) researchers Clement Lecigne and Benoit Sevens said in a write-up.

Variston, which has a bare-bones website, claims to "offer tailor made Information Security Solutions to our customers," "design custom security patches for any kind of proprietary system," and support the "the discovery of digital information by \[law enforcement agencies\]," among other services.

The vulnerabilities, which have been patched by Google, Microsoft, and Mozilla in 2021 and early 2022, are believed to have been utilized as zero-days to help customers install malware of their choice on the targeted systems.

Heliconia comprises a trio of components, namely Noise, Soft, and Files, each of which are responsible for deploying exploits against bugs in Chrome, Windows, and Firefox, respectively.

Noise is designed to take advantage of a security flaw in the Chrome V8 engine JavaScript engine that was patched in August 2021 as well as an unknown sandbox escape method called "chrome-sbx-gen" to enable the final payload (aka "agent") to be installed on targeted devices.

However, the attack banks on the prerequisite that the victim accesses a booby-trapped webpage to trigger the first-stage exploit.

Heliconia Noise can be additionally configured by the purchaser using a JSON file to set different parameters like the maximum number of times to serve the exploits, an expiration date for the servers, redirect URLs for non-target visitors, and rules specifying when a visitor should be considered a valid target.

Soft is a web framework that's engineered to deliver a decoy PDF document featuring an exploit for CVE-2021-42298, a remote code execution flaw impacting Microsoft Defender that was fixed by Redmond in November 2021. The infection chain, in this case, entailed the user visiting a malicious URL, which then served the weaponized PDF file.

The Files package – the third framework – contains a Firefox exploit chain for Windows and Linux that leverages a use-after-free flaw in the browser that was reported in March 2022 (CVE-2022-26485). However, it's suspected that the bug was likely abused since at least 2019.

Google TAG said it became aware of the Heliconia attack framework after receiving an anonymous submission to its Chrome bug reporting program. It further noted that there's no current evidence of exploitation, either indicating the toolset has been put to rest or evolved further.

The development arrives more than five months after the tech giant's cybersecurity division linked a previously unattributed Android mobile spyware, dubbed Hermit, to Italian software outfit, RCS Lab.

"The growth of the spyware industry puts users at risk and makes the Internet less safe, and while surveillance technology may be legal under national or international laws, they are often used in harmful ways to conduct digital espionage against a range of groups," the researchers said.
