During our research we observed multiple variants impacting Windows and Linux systems.


In comparison, we see less flexibility in FY 2022 Q1 and Q3 – threat actors only offered an average of about 30% as a price drop.


While the chat applications indeed have real chat features (although the communication is not anonymous, as advertised), they have backdoor routines and file-stealing behaviors that get triggered when specific words are sent to the app: collecting and harvesting all SMS messages, contacts, and accounts.


As part of TAG's mission to counter serious threats to Google and our users, we've published analysis on a range of persistent threats including government-backed attackers, commercial surveillance vendors, and serious criminal operators.


Our investigation has also uncovered that Earth Berberoka targets the Windows, Linux, and macOS platforms, and uses malware families that have been historically attributed to Chinese-speaking individuals.


A new form is displayed if the information is not provided via command prompt.


In one sample we examined, we found a total of 844 hostnames.


We received leads from Graphika that supported us in this investigation.


Safe Browsing also notifies webmasters when their websites are compromised by malicious actors and helps them diagnose and resolve the problem so that their visitors stay safer.


Once the vulnerability was discovered, Palo Alto Networks threat researchers quickly began reverse-engineering the patch that remediated this vulnerability and were able to produce a working proof of concept (PoC) in a very short time.


The second-stage shellcode then performs API hooking inside the targeted process.


This malware combines features of existing trojans in the malware family’s development, based on the adjustments TICK made as we analyzed their test versions.


Injects final payload into "lsass.exe"  Stage 3 - Final Payload  Installs itself as a Windows service


Today, we’re sharing recent findings on government-backed phishing, threats and disinformation, as well as a new bulletin to share information about actions we take against accounts that we attribute to coordinated influence campaigns.


Another noteworthy trend we observed was that some sellers provided email addresses with customizable usernames at "californiacolleges.edu".


The attacker can add a shortcut with a crafted payload by exploiting the XSS vulnerability, which replaces part of the original script from the webmail system with malicious JavaScript code.


Infections typically begin with emails carrying malicious macro documents, drive-by exploit kits targeting browsers, or direct attacks on servers running vulnerable software.


The exploit code used in these attacks only targets IE versions 9, 10 and 11, but earlier versions are still vulnerable.


Unit 42 released details about a vulnerability that affects Android devices running operating systems older than 8.0 Oreo.

According to Microsoft’s security release notes, any system created, or which has updated its OMI package, after Aug. 11, 2021, should automatically be patched.


The framework used to deliver and manage these XSS attack scripts is called “XSSER.ME” or “XSS Framework.” The stolen session keys and browser cookies are also sent to the framework to store in the database.   While a stolen session key may allow the attacker to log into their target’s webmail system without a password, note that this is not the Earth Wendigo operation's ultimate goal.       Figure 7.


CryptoWall isn’t the only threat that communicates over Tor and if your network doesn’t have an explicit reason to allow anonymization networks, you should consider blocking the application altogether with your firewall.

In this case, the DeviceIoControl is inside a loop that iterates through the list of processes mentioned above.


Additionally, many of the files related to the Urpage domains are auto-extractable files that drop Delphi or VB backdoor and open a decoy document.


The threat actors will use an installer to install SmileSvr as a system service and drop a DAT file that contains encoded C&C information.


For example, if you are the executive assistant for a CEO, you could be the target of an attack like this (“Bob” in our scenario above) so that you in turn are used to carry out an attack (“Alice” in our scenario above) against your CEO (who then becomes “Bob” in our scenario above).  Because of the nature of the attack, unless you verify each and every email you receive, it’s unlikely that you’ll necessarily be able to spot and thwart an attack.


We terminated 3 YouTube channels as part of our investigation into coordinated influence operations linked to France.


The following Python script can be used to generate the keys.


Both have compromised websites where the malware samples are hosted and delivered to victim machines.

The oRAT droppers that we found in our analysis were a MiMi chat application built using the Electron JS framework and a DMG (disk image) file.


Far from the hypothesized "huge amount of variability" in mutex names, likely hypothesized due to the seemingly random appearance of them, practical mutex usage is embarrassingly consistent.


Targets typically had to navigate through at least one redirect before landing on a phishing domain.


(ref: Binance on Twitter ).


The remote server can also send the following example response.


Based on the security advisory issued by Atlassian, it appears that the exploit is indeed an unauthenticated, remote code execution vulnerability.


Threat actors have used N-days shortly after a patch is released to capitalize on the patching delay of their targets.


The macros process the downloaded payload with each number encrypted in XOR with a constant hardcoded value of 106.

One of the campaigns has direct infrastructure overlap with a campaign targeting security researchers which we reported on last year.


According to Shodan, on March 4, there were more than 266,000 Exchange Servers vulnerable to the ProxyLogon vulnerability, a day after the patch was released.


Speaking of data exfil, in the first half we saw APT actors utilize cloud-based file storage to exfiltrate their stolen data.


These include Getpass.exe and Mail.exe, which are password and information stealers.


These were published on Google Play — but have since been taken down — and third-party app marketplaces.


In so doing, it eliminates the need for endless back-and-forth communications between ISV and prospective customer.


There’s a very good reason why AWS remains a leader in cloud computing.


Interestingly, after decoding the VBS, we saw what appeared to be a programming mistake by the attacker.

The phishing typically started with a customized email introducing the company and its products.


To add resilience to their infrastructure, the operators have also implemented a backup mechanism using the Bitcoin blockchain.


It provides a comprehensive defense tailored to protect organizations against targeted attacks and advanced threats through specialized engines, custom sandboxing, and seamless correlation across the entire attack lifecycle, allowing it to detect threats like TICK’s attacks even without any engine or pattern update.


Even though Microsoft Windows today features a robust user access control system, that system has inherent limitations.


Obviously, many organizations are moving quickly to the cloud and, as such, need to be thinking about how to secure it.


Since our last update, TAG has observed a continuously growing number of threat actors using the war as a lure in phishing and malware campaigns.

There are several reasons that these devices are favored by an attacker — the infrequency of patching, the lack of security software, and the limited visibility of defenders.


The actors behind this campaign, which we attribute to a group of hackers recruited in a Russian-speaking forum, lure their target with fake collaboration opportunities (typically a demo for anti-virus software, VPN, music players, photo editing or online games), hijack their channel, then either sell it to the highest bidder or use it to broadcast cryptocurrency scams.


As one example, we've seen new activity from “hack-for-hire” firms, many based in India, that have been creating Gmail accounts spoofing the WHO.


Once people clicked on the emails, they were presented with phishing pages designed to trick them into providing their Google account credentials.


To run the exploit in our virtual environment, we decided to write a loader in Python which did the following:  For our payload, we wrote a simple bash script which runs id and pipes the result to a file in /tmp.
