Apple Security Advisory 2022-08-17-2

APTs continue to exploit the dynamic job market and the persistent phenomenon of remote working, as explored by PwC at Black Hat USA.

Fake job offers have become a top phishing tactic for state-sponsored threat actors to lure in unsuspecting targets in the wake of the COVID-19 pandemic, as many reconsider their careers amid growing demand for skilled workers and managers.

The cyber-threat analyst team at PwC, which has followed a prime example of this (the Lazarus Group's Operation In(ter)ception) closely, presented a detailed account of the Lazarus campaign and how the group implemented the strategy during last week's Black Hat USA 2022 conference in Las Vegas.

PwC principal threat analyst Sveva Vittoria Scenarelli, who studies advanced persistent threats (APTs) in the Asia-Pacific region with an emphasis on North Korea, noted that the stakes are high.

"This is an espionage-motivated campaign that is incredibly persistent in targeting the aerospace sector, the defense industrial base, manufacturing chemical sector, for everything from military secrets to intellectual property to confidential information of strategic interest," Scenarelli explained during her presentation at Black Hat, called "Talent Need Not Apply: Tradecraft and Objectives of Job-themed APT Social Engineering."

The Cybersecurity & Infrastructure Security Agency (CISA) agrees, and has warned that the threat actors (aka APT38, Black Artemis, BlueNoroff, Hidden Cobra, and Stardust Chollima) "employ malicious cyberactivity to collect intelligence, conduct attacks, and generate revenue."

Scenarelli explained that Lazarus follows up with its targets via messaging apps such as WhatsApp.

This is "to make sure that the victims do open the malicious viewer documents or the malicious executables that the threat actor has sent," she said. "Black Artemis will also set up domains. This can be for command and control of its malicious implants to send emails that appear to come from on a legit site, or indeed to perform Web exploitation as an initial access method."

Scenarelli explained that Black Artemis creates domains that spoof prominent job search websites like Indeed, with attractive positions at high-profile companies such as Google and Oracle. She underscored that many sites look legitimate, though there are obvious signs they are fake. For instance, the Indeed decoy site URL is Indeed.US.org, she said. Scenarelli noted that the job descriptions disguised as .docx, .pdf, or .rtx files launch when the victims click on the documents, which may enable macros.

Similarly, Scenarelli recalled another attack by the group, which made off with $625 million in cryptocurrency. She warned that this variant, which PwC researchers call "Black Alicanto," is financially motivated and dangerous. In the wake of Microsoft recently disabling macros in Office documents, Scenarelli said this malware might use .lnk files, perhaps embedded in password-protected Microsoft Word documents.

"Threat actors are having to pivot a bit in their initial access techniques and using more and more .lnk files, ISO files, MSI installers, and stuff like that," she said. But in the background, she noted, the .lnk file is calling MSHDA.exe, which connects to a remote server to pull down a malicious JavaScript script that PwC calls "Cabbage Loader."

This script places a .lnk file in the victim's startup folder "to ensure persistence and then pulls down a whole series of other JavaScript payloads," she explained. "These are essentially profilers that want to make sure that the actual person that's interacting with them is not a sandbox, is not a researcher, but it's actually a target of interest."

Scenarelli concluded that Lazarus and other North Korea-based threat actors continue to exploit the growing demand for skilled people, who, despite their training and awareness of threats, can be caught off guard.

"The job market right now is a really key area for North Korea-based threat actors," she said. "So, keep your eyes peeled, make sure you're aware of whom you're interviewing. And for the love of all that is holy, don't open those links that you get sent on LinkedIn, do not open them."

We take a look at a Microsoft warning related to tech support scammers sending out bogus USB sticks in the mail.



(Read more...)




The post Tech support scammers target Microsoft users with fake Office 365 USB sticks appeared first on Malwarebytes Labs.

Microsoft is a hot target for scammers and acts of fraud. For example, tech support scam websites cover themselves in Windows branding and messages. Phone scammers claim to be calling directly from Microsoft. If it’s not a Bill Gates themed lottery spam mail in your mailbox, it’s a fake Excel spreadsheet laden with dangerous Macros.

Well, Microsoft is now issuing a warning related to a recent scam riding on the coat-tails of their branding. Criminals are producing very slickly designed physical boxes made to look like Microsoft products. The boxes say “Microsoft Office Professional Plus” on the front, along with “product key inside - no disc” at the bottom.

Opening the box reveals a solitary USB stick and a product key. This is about to go as horribly wrong as you'd expect.

**Why mysterious USB sticks are probably not your friend**

We’ve warned at length about the dangers of plugging random USB sticks into your device. Whether a stranger has given you it in the street as part of a giveaway, or you found it on the floor, or even received it at an event, there’s an element of risk involved.

You simply do not know what lurks on the stick if someone else has used it first. Of course, some fancy Microsoft branding and a large box will work wonders on the “please trust my fancy Microsoft box” front. Some sort of promotional copy of an otherwise expensive document editing tool? Even better.

What happens if someone is unfortunate enough to plug it in?

**What's in the box?**

Sadly, people expecting a freebie Office Professional Plus do not receive what they were expecting. What actually happens is victims see a popup for a fake tech support line. Phoning the number is a short step to handing over remote control to the scammers.

Based on the typical tactics, the scammers will install a form of remote access software onto the target PC. At this point, they can pretty much do what they want. Do you have bank details stored on a notepad on your desktop? They can just open it up and take it. Will they install some dubious software or even malware to get up to who knows what? They might, and the victim would probably be none the wiser.

If they stick to the whole “here’s a product of some sort” angle, they may well just ask the victim to make a payment of some sort over the phone. Whatever the end-game, it’s not going to benefit the person sitting in front of their computer.

**It's pretend virus time**

In this particular instance, the fake Microsoft outfit went with the “You have a virus, call us” approach. They did indeed attempt to install remote access software. Once the non-existent problem was “solved”, the victim was passed over to a phony Office 365 subscription team.

Microsoft has pointed out that this isn’t a very common tactic. While it has happened in the past, you shouldn’t start living in fear of novelty oversized Microsoft boxes landing on your doorstep to ruin your day.

Should you receive a novelty oversized Microsoft box, don’t panic. Check out Microsoft’s list of tips for staying safe where Microsoft-centric tech support scams are concerned. Report the box directly to Microsoft’s technical support scam reporting page. If there’s anything suspicious, you’ll have some steps to follow and hopefully a safe and timely resolution to follow. Either way: do not plug the USB stick into your computer and you’ll be fine.

Tech support scammers target Microsoft users with fake Office 365 USB sticks

Version 2.0 of the ransomware group's operation borrows extortion tactics from the LockBit 3.0 group.

The BlackByte ransomware group, which has connections to Conti, has resurfaced after a hiatus with a new social media presence on Twitter and new extortion methods borrowed from the better-known LockBit 3.0 gang.  

According to reports, the ransomware group is using various Twitter handles to promote the updated extortion strategy, leak site, and data auctions. The new scheme lets victims to pay to extend the publishing of their stolen data by 24 hours ($5,000), download the data ($200,000) or destroy all the data ($300,000). It's a strategy the LockBit 3.0 group already pioneered.

"It is not surprising BlackByte is taking a page out of LockBit's book by not only announcing a version 2 of their ransomware operation but also adopting the pay to delay, download, or destroy extortion model," says Nicole Hoffman, senior cyber-threat intelligence analyst at Digital Shadows, who calls the market for ransomware groups "competitive" and explains LockBit is one of the most prolific and active ransomware groups globally.

Hoffman adds it is possible BlackByte is trying to gain a competitive advantage or trying to gain media attention to recruit and grow its operations.

"Although the double-extortion model is not broken by any means, this new model may be a way for groups to introduce multiple revenue streams," she says. "It will be interesting to see if this new model becomes a trend among other ransomware groups or just a fad that is not widely adopted."

Oliver Tavakoli, CTO at Vectra, calls this approach an "interesting business innovation."

"It allows smaller payments to be collected from victims who are almost certain they won’t pay the ransom but want to hedge for a day or two as they investigate the extent of the breach," he says.

John Bambenek, principal threat hunter at Netenrich, points out ransomware actors have played around with a variety of models to maximize their revenue.

"This almost looks like an experiment on if they can get lower tiers of money," he says. "I just don't know why anyone would pay them anything except for destroying all the data. That said, attackers, like any industry, are experimenting with business models all the time."

**Causing Disruption With Common Tactics**

BlackByte has remained one of the more common ransomware variants, infecting organizations worldwide and previously employing a worm capability similar to Conti's precursor Ryuk. But Harrison Van Riper, senior intelligence analyst at Red Canary, notes that BlackByte is just one of several ransomware-as-a-service (RaaS) operations that have the potential to cause a lot of disruption with relatively common tactics and techniques.

"Like most ransomware operators, the techniques BlackByte uses are not particularly sophisticated, but that doesn’t mean they aren’t impactful," he says. "The option to extend the victim's timeline is likely an effort to get at least some sort of payment from victims who may want extra time for a variety of reasons: to determine legitimacy and scope of the data theft or continue ongoing internal discussion on how to respond, to name a couple of reasons."

Tavakoli says cybersecurity pros should view BlackByte less as an individual static actor and more as a brand that can have a new marketing campaign tied to it at any time; he notes the set of underlying techniques to carry off the attacks seldom change.

"The precise malware or entry vector utilized by a given ransomware brand may change over time, but the sum of techniques used across all of them are pretty constant," he says. "Get your controls in place, ensure you have detection capabilities for attacks which target your valuable data, and run simulated attacks to test your people, processes and procedures."

**BlackByte Targets Critical Infrastructure**

Bambenek says that because BlackByte has made some mistakes (such as an error with accepting payments in the new site), from his perspective it may be a little lower on the skill level than others.

"However, open source reporting says they are still compromising big targets, including those in critical infrastructure," he says. "The day is coming when a significant infrastructure provider is taken down via ransomware that will create more than just a supply chain issue than we saw with Colonial Pipeline."

In February, the FBI and US Secret Service released a joint cybersecurity advisory on BlackByte, warning that attackers deploying the ransomware had infected organizations in at least three US critical infrastructure sectors.

Separate fixes to macOS and iOS patch respective flaws in the kernel and WebKit that can allow threat actors to take over devices and are under attack.

Separate fixes to macOS and iOS patch respective flaws in the kernel and WebKit that can allow threat actors to take over devices and are under attack.

Apple is urging macOS, iPhone and iPad users immediately to install respective updates this week that includes fixes for two zero-days under active attack. The patches are for vulnerabilities that allow attackers to execute arbitrary code and ultimately take over devices.

Patches are available for effected devices running iOS 15.6.1 and macOS Monterey 12.5.1. Patches address two flaws, which basically impact any Apple device that can run either iOS 15 or the Monterey version of its desktop OS, according to security updates released by Apple Wednesday.

One of the flaws is a kernel bug (CVE-2022-32894), which is present both in iOS and macOS. According to Apple it is an “out-of-bounds write issue \[that\] was addressed with improved bounds checking.”

The vulnerability allows an application to execute arbitrary code with kernel privileges, according to Apple, which, in usual vague fashion, said there is a report that it “may have been actively exploited.”

The second flaw is identified as a WebKit bug (tracked as CVE-2022-32893), which is an out-of-bounds write issue that Apple addressed with improved bounds checking. The flaw allows for processing maliciously crafted web content that can lead to code execution, and also has been reported to be under active exploit, according to Apple. WebKit is the browser engine that powers Safari and all other third-party browsers that work on iOS.

**Pegasus-Like Scenario**

The discovery of both flaws, about which little more beyond Apple’s disclosure are known, was credited to an anonymous researcher.

One expert expressed worry that the latest Apple flaws “could effectively give attackers full access to device,” they might create a Pegasus-like scenario similar to the one in which nation-state APTs barraged targets with spyware made by Israeli NSO Group by exploiting an iPhone vulnerability.

“For most folks: update software by end of day,” tweeted Rachel Tobac, the CEO of SocialProof Security, regarding the zero-days. “If threat model is elevated (journalist, activist, targeted by nation states, etc): update now,” Tobac warned.

**Zero-Days Abound**

The flaws were unveiled alongside other news from Google this week that it was patching its fifth zero-day so far this year for its Chrome browser, an arbitrary code execution bug under active attack.

The news of yet more vulnerabilities from top tech vendors being barraged by threat actors demonstrates that despite the best efforts from top-tier tech companies to address perennial security issues in their software, it remains an uphill battle, noted Andrew Whaley, senior technical director at Promon, a Norwegian app security company.

The flaws in iOS are especially worrying, given the ubiquity of iPhones and users’ utter reliance on mobile devices for their daily lives, he said. However, the onus is not only on vendors to protect these devices but also for users to be more aware of existing threats, Whaley observed.

“While we all rely on our mobile devices, they are not invulnerable, and as users we need to maintain our guard just like we do on desktop operating systems,” he said in an email to Threatpost.

At the same time, developers of apps for iPhones and other mobile devices also should add an extra layer of security controls in their technology so they are less reliant on OS security for protection, given the flaws that frequently crop up, Whaley observed.

“Our experience shows that this is not happening enough, potentially leaving banking and other customers vulnerable,” he said.

**SQL injection Bypass**

The above injection payload is as follows

id+AND+(SELECT+1+FROM+(SELECT(SLEEP(5)))a)

The environment here is from idea, but idea has a lot of error reports, many functions are not available, I changed to Windows one-click deployment  
  
After building it, debug it remotely with idea  
  
When you try to reproduce this vulnerability again, you will be prompted with an XSS interception  
  
  
It was curious at the time why this was XSS intercepted and not SQL intercepted? Look at the code  
  
The specific detection logic is in the filter method in SecurityUtil.java, so let's look at the code logic here  
  
Briefly, the main thing here is to get the values of the request parameters, and then pass them one by one to the following detection logic  
  
Since we just prompted for an XSS attack, we will follow directly into the method antixss to see the specific implementation logic  
Next you will come to Antixss.Java

    src/main/java/com/cloudwebsoft/framework/security/AntiXSS.java
    

  
The antiXSS method is called by passing in the html to be detected and a true  
  
Follow directly in to see  
  
Check the \_antiXSS method, where the content is passed in is the content to be detected  
  
Here is the specific detection logic, but I'm only looking at the stripScriptTag method here, because it is the content inside this method that is detected, and our focus is only on what parameters are detected  
  
Mainly by means of regularity and case-insensitive because of CASE_INSENSITIVE  
  
Pull the following when you can see, in fact, and or sleep is filtered, create a new test class, and adjust it to know  
  
Remove AND  
  
The statement is normal, put back and remove sleep, the statement is normal, so since this is the case, replace and with &&, you can  
  
statement returns normally, then after returning here  
  
Returning to SecurityUtil.java, it will enter the logic of SQL injection, following the isValidSqlParam method  
  
Follow the sql_inj method  
  
We have already bypassed the detection of and and need to bypass the code logic in the second box  
  
The main logic here is to separate inj\_str using |, which will generate a list to inj\_stra\[\], and then iterate through the list, each loop will use the indexOf method to determine whether the value in inj\_stra\[i\] is in str, that is, if indexOf returns > 0 value exists, and vice versa, it does not exist, here you can also write a class tuned  
  
  
In the sixth loop, which is when select is detected, then it is obvious that you need to bypass select  
Here I was going to try to use

&& extractvalue(1,concat('~',database()))

Unfortunately, '~' will be detected as XSS, so this method does not work  
  
The && here needs to be converted to url encoding, otherwise this request will report 400  
  
So we can only think of ways to select this keyword, here is a bypass of the payload

id+%26%26+(/\*!%53eLEct\*/+1+FROM+(/\*!%53eLEct\*/(sleep(5)))a)

  
Tips: Here just by looking at the screenshot you may think that you can bypass it with SELECT capitalization, but in fact it will be converted to lowercase before calling the sql_inj method  
  
So there is no way to capitalize to bypass

**Function implementation entrance**

  
  
First will get the get parameter code, if the code parameter is empty, then get the Get parameter moduleCode and assign it to code, if there is no moduleCode in the get parameter, then get the formCode and copy it to code, here the code parameter passed in is personbasic  
  
Continue to the next page  
  
Here is the OA developer's own implementation of the SQLBuilder class  
  
  
Follow this method  
  
Follow such as getModuleListSqlAndUrlStr method, then a sql str will be returned, continue down the line is the place that causes SQL injection  
  
Follow up this listResult method  
  
The statements will then be spelled out in the middle  
  
The executeQuery statement is then executed  
  
The difference between the above and the SQL statement is that one is the count spliced in and the other is the original passed in  
  
This is followed by a return, which is executed here with a 5-second wait, so it causes an injection

FLIX AX8 1.46.16 Remote Command Execution

The Donot Team threat actor has updated its Jaca Windows malware toolkit with improved capabilities, including a revamped stealer module designed to plunder information from Google Chrome and Mozilla Firefox browsers.

The **Donot Team** threat actor has updated its **Jaca** Windows malware toolkit with improved capabilities, including a revamped stealer module designed to plunder information from Google Chrome and Mozilla Firefox browsers.

The improvements also include a new infection chain that incorporates previously undocumented components to the modular framework, Morphisec researchers Hido Cohen and Arnold Osipov disclosed in a report published last week.

Also known as APT-C-35 and Viceroy Tiger, the Donot Team is known for setting its sights on defense, diplomatic, government, and military entities in India, Pakistan, Sri Lanka, and Bangladesh, among others at least since 2016.

Evidence unearthed by Amnesty International in October 2021 connected the group's attack infrastructure to an Indian cybersecurity company called Innefu Labs.

Spear-phishing campaigns containing malicious Microsoft Office documents are the preferred delivery pathway for malware, followed by taking advantage of macros and other known vulnerabilities in the productivity software to launch the backdoor.

The latest findings from Morphisec build on a prior report from cybersecurity company ESET, which detailed the adversary's intrusions against military organizations based in South Asia using several versions of its yty malware framework, one of which is Jaca.

This entails the use of RTF documents that trick users into enabling macros, resulting in the execution of a piece of shellcode injected into memory that, in turn, is orchestrated to download a second-stage shellcode from its command-and-control (C2) server.

The second-stage then acts as a channel to retrieve a DLL file ("pgixedfxglmjirdc.dll" from another remote server, which kick-starts the actual infection by beaconing system information to the C2 server, establishing persistence via a Scheduled Task, and fetching the next-stage DLL ("WavemsMp.dll").

"The main purpose of this stage is to download and execute the modules used to steal the user's information," the researchers noted. "To understand which modules are used in the current infection, the malware communicates with another C2 server."

The C2 domain, for its part, is obtained by accessing an embedded link that points to a Google Drive document, allowing the malware to access a configuration that dictates the modules to be downloaded and executed.

These modules expand on the malware's features and harvest a wide range of data such as keystrokes, screenshots, files, and information stored in web browsers. Also, part of the toolset is a reverse shell module that grants the actor remote access to the victim machine.

The development is yet another sign that threat actors are actively adapting their tactics and techniques that are most effective in gaining initial infection and maintaining remote access for extended periods of time.

"Defending against APTs like the Donot team requires a Defense-in-Depth strategy that uses multiple layers of security to ensure redundancy if any given layers are breached," the researchers said.

DoNot Team Hackers Updated its Malware Toolkit with Improved Capabilities

A financially motivated cybercrime group has been linked to an ongoing wave of attacks aimed at hospitality, hotel, and travel organizations in Latin America with the goal of installing malware on compromised systems.

A financially motivated cybercrime group has been linked to an ongoing wave of attacks aimed at hospitality, hotel, and travel organizations in Latin America with the goal of installing malware on compromised systems.

Enterprise security firm Proofpoint, which is tracking the group under the name TA558 dating all the way back to April 2018, called it a "small crime threat actor."

"Since 2018, this group has used consistent tactics, techniques, and procedures to attempt to install a variety of malware including Loda RAT, Vjw0rm, and Revenge RAT," the company's threat research team said in a new report.

The group has been operational at a higher tempo in 2022 than usual, with intrusions mainly geared towards Portuguese and Spanish speakers in Latin America, and to a lesser extent in Western Europe and North America.

Phishing campaigns mounted by the group involve sending malicious spam messages with reservation-themed lures such as hotel bookings that contain weaponized documents or URLs in a bid to entice unwitting users into installing trojans capable of reconnaissance, data theft, and distribution of follow-on payloads.

The attacks have subtly evolved over the years: The ones spotted between 2018 and 2021 leveraged emails with Word documents that either contained VBA macros or exploits for flaws such as CVE-2017-11882 and CVE-2017-8570 to download and install a mixture of malware such as AsyncRAT, Loda RAT, Revenge RAT, and Vjw0rm.

In recent months, however, TA558 has been observed pivoting away from macro-laden Microsoft Office attachments in favor of URLs and ISO files to achieve initial infection, a move likely in response to Microsoft's decision to block macros in files downloaded from the web by default.

Of the 51 campaigns carried out by the group so far this year, 27 of them are said to have incorporated URLs pointing to ISO files and ZIP archives, in comparison to just five campaigns altogether from 2018 through 2021.

Proofpoint further noted that the intrusions chronicled under TA558 are part of a broader set of malicious activities focusing on victims in the Latin American region. But in the absence of any post-compromise activity, it's suspected that TA558 is a financially motivated cybercriminal actor.

"The malware used by TA558 can steal data including hotel customer user and credit card data, allow lateral movement, and deliver follow-on payloads," the researchers said. "Activity conducted by this actor could lead to data theft of both corporate and customer data, as well as potential financial losses."
