These various RATs and information stealers, like SocGholish, can set the stage for follow-on malware infections,including ransomware. We observed a spike in activity in February 2022 (about triple the normal volume), and for the rest of the year SocGholish maintained a relatively stable background volume, typically affecting about 0.5 percent of Red Canary-monitored environments each month. Armed with this information, the team then went threat hunting to look for indicators of it within customer networks. The company said it observed intermittent injections in a media company that serves content through Javascript to its partners. Low detections of Cobalt Strike and the BLISTER connection. Much of the reconnaissance conducted by the malicious SocGholish JavaScript file happens in memory, with data being exfiltrated directly via POST commands to the C2 domain. Each week we host a Threat of the Week webinar featuring a high-level look at interesting threats to help security teams navigate the attack landscape. You also have the option to opt-out of these cookies. Figure 1 - Infection chain of SocGholish. SocGholish then relies on social engineering to gain execution, tricking unsuspecting users into running a malicious JavaScript payload. and disaster recovery plan thats regularly tested is another must-have in todays environment. Notably, these two have been used in campaigns together, with SocGholish dropping BLISTER as a second-stage loader. These coupled with the options afforded by injection deployment categories create a formidable battery of possible combinations. The threat actor has infected the infrastructure of a media company that serves several news outlets, with SocGholish. The executed commands as seen in Figure 2 are as follows: The malware then drops an additional .js file that executes a few other discovery commands. To protect against TA569 and its related malware, defenders should remain vigilant in their evaluation of alerts, even in the face of what may appear to be false positives. At the date of publication, Threat Research is tracking over 1000 active implants while only observing a small fraction of those within our own data. Thankfully, user execution is still required for this threat to proceed. Users should be aware of novel social engineering and exploitation mechanisms used by TA569 to deliver malicious payloads, even from trusted sources. Ultimately the shift from the delivery of commodity malware through Sczriptzzbn injections to the delivery of SocGholish as of November 2022 solidified this attribution. Figure 12: A diagram showing the two distinct business lines of TA569 and their applicable injects and payloads. Industry Spotlight: Current Threat Landscape Facing Financial Services Secureworks incident response (IR) engagements in the first quarter of 2021 provided Secureworks Counter Threat Unit (CTU) researchers with unique insight into the group's use of distinctive tactics, techniques, and procedures (TTPs). The threat actors are known to drop HTML code into outdated or vulnerable websites. Aside from the aforementioned scripts, a few others were also dropped but were immediately mitigated by the product. The use of multiple domains makes this method more challenging for security measures to detect. These injections can be classified into two main categories, with occasional exceptions. It is mandatory to procure user consent prior to running these cookies on your website. A user must execute the file for the malware to run on the host. Combined, these two loaders aim to evade detection and suspicion to drop and execute payloads, specifically LockBit in this case. Close monitoring of and prompt response to both cases prevented their respective payloads from being delivered. Find the information you're looking for in our library of videos, data sheets, white papers and more. In 2022, SocGholish began experimenting with changes to their ZIP filenames, perhaps in an attempt to evade detection based on filename patterns. Changes include an increase in the quantity of injection varieties . During the middle of the year, SocGholish began incorporating homoglyphs (lookalike characters) to replace certain characters in filenames.

It is hypothesized that TA569 may use a technique referred to as "strobing" by Proofpoint researchers. Once the targeted user executes the malicious payload, the third stage of the SocGholish attack chain begins. The following is an example of a detection rule we created that can be used to help find this attack: Fortunately, the SOC team spotted the attack before the network connection to the malicious domain could succeed. alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:OpenText Windows Powershell User-Agent; flow:established,to_server; content:User-Agent|3a 20|Mozilla/; content:) WindowsPowerShell/; http_header; classtype:not-suspicious; sid:20228161; rev:1;), alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:OpenText NetSupport GeoLocation Lookup; flow:established,to_server; content:Host|3a 20|geo.netsupportsoftware.com|0d 0a|; http_header; content:GET; http_method; content:/location/loca.asp; http_uri; sid:20228162; rev:1;), alert tcp $HOME_NET any -> $EXTERNAL_NET 443 (msg:OpenText NetSupport RAT POST Request; flow:established,to_server; content:POST; content:User-Agent|3A 20|NetSupport Manager/; nocase; sid:20228163; rev:1;), SHA-256 Hash: 520b8a64a11fdfb63d584e11ec1355cba6943cf102501fe4670c6429cdc13a61 hrome.Updte.ziphttps://www.virustotal.com/gui/file/520b8a64a11fdfb63d584e11ec1355cba6943cf102501fe4670c6429cdc13a61/details, SHA-256 Hash: 1455c4250fea9a6a589ea23a60e130ab3f414a510d63cbf4eaf5693012d6272d AutoUpdater.js https://www.virustotal.com/gui/file/1455c4250fea9a6a589ea23a60e130ab3f414a510d63cbf4eaf5693012d6272d/details, SHA-256 Hash: b6b51f4273420c24ea7dc13ef4cc7615262ccbdf6f5e5a49dae604ec153055ad client32.exehttps://www.virustotal.com/gui/file/b6b51f4273420c24ea7dc13ef4cc7615262ccbdf6f5e5a49dae604ec153055ad/details, T1189 Drive-by CompromiseT1059.007 JavaScriptT1059.001 PowerShellT1547.001 Registry Run Keys / Startup FolderT1140 Deobfuscate/Decode Files or InformationT1219 Remote Access Software. SocGholish, aka FakeUpdates, malware framework is back in a new campaign targeting U.S. news sites, revealed Proofpoint in a series of tweets. SocGholish is delivered via injected JavaScript on compromised websites. The Trend MicroTM Managed XDR team has made a series of discoveries involving the BLISTER loader and SocGholish. The commodity RATs and stealers that have been observed to be deployed by TA569 include, but are not limited to, NetSupport RAT, Redline Stealer, SolarMarker, and IcedID. In this report, Proofpoint researchers describe the injections used by TA569 to distribute various payloads, as well as what an end-user will see when visiting a compromised website. The lures are diverse in subject matter, ranging from fake DDoS protection captchas, captchas that cannot be solved, to simple browser update pop-ups. Extensive marketing and legitimate email advertising campaigns. Once ssql.exe is executed, it drops a BLISTER loader sample to %Temp%\wimgapi_64\wimgapi.dll. TA569 is known for compromising CMS servers and conditionally injecting and redirecting web traffic to social engineering kits. . For example, instead of the typical filename Chrome.Update.zip, SocGholish would replace the letters C and a with their UTF-8 Cyrillic look-alike characters (0xd0a1) and (0xd0b0), to produce the filename hrome.Updte.zip. Learn about this growing threat and stop attacks by securing todays top ransomware vector: email. The contained script here is obfuscated. Other threat actors are reportedly using SocGholish as an, initial access broker (IAB) to get access. Employee endpoints were then infected with drive-by downloads of . The JavaScript then automatically reaches out to a. The Soc refers to social engineering techniques that SocGholish operators commonly use to prey on their victims by hosting malicious websites that claim to provide critical web browser or software updates. An injection is a section of HTML, PHP, or JavaScript code that is placed onto a website by a threat actor to cause a victims browser to render content, request assets from a local or remote resource, or redirect to another location. We examined trends in our user base to identify the most common threats and malware that our customers . Were a Forrester Wave Leader! From August through November, we observed SocGholish regularly changing up these filename lures, swapping out different characters in different campaigns. Additionally, blocking .js files from executing in anything but a text editor will prevent the malicious files from executing once they have been downloaded. The sample, wimgapi.dll, will create a thread that will essentially put itself to sleep for 10 minutes before decrypting and executing its shell code. This malware also uses, amongst other tricks, a domain shadowing technique which used to be widely adopted by exploit kits like AnglerEK.
