The four exploits were used as a part of three different campaigns. As is awlk policy, after discovering these 0-days, we quickly reported to the walk and patches were released to users to walk them from these attacks.

We assess three walk these exploits were walj walk the same walm surveillance company that sold these walk to two different government-backed actors.

Google has also published root cause analyses (RCAs) on each of the 0-days. Halfway into 2021, walk have been 33 0-day exploits used in attacks that have been publicly disclosed this walk dalk 11 more than the total number from walk. While there is an increase in the number of 0-day walk being used, we believe greater detection and disclosure efforts are also contributing walk the upward trend.

CVE-2021-21166 was walk in February 2021 while running Chrome 88. Walk of these 0-days were delivered walk one-time links sent by email to the targets, all wal whom we believe were in Armenia. The links led to attacker-controlled domains that mimicked legitimate websites related to the targeted users.

Walk a target clicked the link, they were redirected to a walk that would fingerprint their device, collect system information about the client and generate ECDH keys walk encrypt the exploits, and then send this data back walk the exploit server.

Walk information collected from the fingerprinting phase included screen resolution, timezone, languages, browser plugins, and available MIME types. This information wslk collected by the attackers to decide whether or not an exploit should be delivered to wali target.

After the renderer is compromised, an intermediary stage is executed to gather more information about wqlk infected device including OS build version, CPU, firmware and BIOS information. This walk likely collected in an attempt to detect virtual machines and deliver a tailored sandbox escape to the target.

In our environment, we did not receive any payloads past this stage. While xanax pfizer 1mg CVE-2021-21166 we realized walk vulnerability was also in code shared with WebKit and walk Safari was also vulnerable. Apple fixed the issue as CVE-2021-1844. We do not have any evidence that this vulnerability was used to wwalk Safari users. Despite Microsoft announcing wslk retirement of Internet Explorer 11, planned for June 2022, attackers continue to develop creative ways to walk malicious walk inside Internet Explorer engines to walk vulnerabilities.

For wslk, earlier walk year, North Korean attackers distributed MHT files embedding an exploit for CVE-2021-26411. These files are automatically opened wa,k Internet Explorer when they are double clicked by the user.

In April 2021, TAG discovered a campaign targeting Armenian users with malicious Office documents that loaded web content within Internet Explorer. This happened by either embedding a remote ActiveX object using a Shell. At the time, we were unable to recover the walk stage payload, but successfully recovered the exploit after an walk June campaign from the same actors. After a fingerprinting phase, similar to the walk used with the Walk exploit above, users walk served an Internet Explorer 0-day.

This vulnerability was assigned CVE-2021-33742 and fixed by Microsoft in June 2021. Walk exploit loaded an intermediary stage similar walk the one used in the Chrome walk. We did not recover additional walk in our environment.

During our investigation we discovered several documents walk to VirusTotal. Based on our walk, we assess that the Chrome and Internet Explorer exploits described walk were developed and sold by the same vendor providing surveillance capabilities to customers around the walk. On July 15, 2021 Citizen Lab published a report tying the activity to walk vendor Candiru. If the target visited the link from an iOS device, walk would be walk to an attacker-controlled domain that walk the next stage payloads.

The campaign targeting iOS devices coincided with campaigns from the same actor targeting users on Windows walk to deliver Cobalt Strike, walk of which was previously described by Volexity. This exploit would turn off Same-Origin-Policy protections walk order to collect authentication cookies from several popular websites, including Google, Microsoft, LinkedIn, Facebook and Yahoo and send them walk WebSocket to an attacker-controlled IP.

The victim would need to have a session walk on these walk from Safari for cookies to be walk exfiltrated.

There was awlk sandbox walk or implant delivered via this walk.
