AcridRain stealer disguised as Grammarly installer
AcridRain is not a new infostealer, it's been around since at least 2018. Over the years, its prevalence has never outshone any other run-of-the-mill stealers, but it continues to be seen here and there. Recently, a new AcridRain command-and-control server has been observed, related to an ongoing drive-by-download campaign. Actors have disguised their AcridRain binary as a Grammarly installer which is a popular cloud-based typing assistant.

A DDoS botnet spreading through CVEs on routers: Condi
Condi is a DDoS-as-a-service botnet whose users can either outright buy the code or rent the botnet to perform DDoS attacks. The botnet itself has been recently spreading by abusing a public vulnerability (CVE-2023-1389) on a line of TP-Link routers. A patch for the vulnerability is already public, so the group behind Condi are just taking advantage of those routers that have not been patched and are found accessible through the internet.

Advance-fee scam exploits Google's own applications and services
In a recent advance fee campaign, Symantec observed threat actors making a slight change in their tactics, techniques and procedures (TTP) by exploiting Google Forms services. As shown in Figure 1, this run consists of emails purporting from financial institutions notifying the recipient of a certain payment. The recipient is asked to send a response on an email address and also, there’s a hyperlinked text with an embedded Google Forms URL.
Figure 1: Email masquerading as payment notification message with Google Forms URL embedded within the content.
As shown in Figure 2, upon clicking the hyperlinked text, a Google form with title “Untitled form” opens. It appears that the threat actors have made use of the form to track responses as it includes a radio button that enables response submission for record purposes.

Advance-fee scammers take advantage of COVID-19 pandemic
Along with the ever-changing threat landscape, the actors behind the advance-fee type of scam are also attempting to leverage COVID-19 pandemic. In one such scam run observed recently by Symantec, emails masqueraded as personal messages are sent to the users to seemingly provide comfort in these challenging times.
Figure 1: Advance-fee scam email masqueraded as a personal email comforting the user with a generous donation.
The scammers reassure the recipient by mentioning that a generous donation awaits and in order to receive it, the user only needs to reach out to the provided email address. As in any similar advance-fee type of scam, the perpetrators expect that by the time the user realizes of being scam victim, he might have already transferred them a considerable amount of money in order to secure the promised "donation".

Afterpay users face holiday season scams
Afterpay is a well-known buy now, pay later (BNPL) service in Australia (also available in other countries) enabling shoppers to divide their purchases into four equal, interest-free installments over a six-week period. With broad acceptance both online and in physical stores, it serves as a convenient payment choice for many Australians.
Phishing and smishing related to this service are hardly a new thing, but during the upcoming holiday season we're bound to observe increased activity. In one such example, Symantec has observed a malicious SMS campaign that's trying to snatch Afterpay users' sensitive information and potentially lead to financial theft or scams. Users are being lured by the actors through account issue social engineering and a shortened Bitly URL that redirects to the malicious website.
Observed SMS (as is, including the "AfrerPay" typo):
AfrerPay:Your afterpay account has an issue, please check:hxxps://bit[.]ly/3Rj94Rz

Agent Tesla and Hannabi Grabber among the malware families leveraging IPFS network
The InterPlanetary File System (IPFS) is a peer-to-peer network for storing and sharing files, data and applications in a form of a distributed file system. It has been recently observed that the IPFS network is being increasingly abused by the various threat actors for the purpose of malware hosting and delivery. Two distinct malware families seen in recent campaigns that leverage IPFS are Agent Tesla and Hannabi Grabber. The observed campaigns tend to use either phishing links pointing to payloads hosted on the IPFS network or malware loaders spread via malspam that retrieve the payloads from repositories within the IPFS network.

Agent Tesla campaign eyes France, Spain, Turkey and North Africa
Agent Tesla (a .NET based information stealer) is being spread to companies around the globe by multiple actors with various goals, including financial gain, corporate espionage, ransomware extortion, and more. Campaigns are intercepted on a daily basis, such as one that has been targeting companies in France, Spain, Turkey and North Africa. The perpetrators pose as a Moroccan company specializing in garment manufacturing and export.
The malicious emails, with the subject "AVIS DE VIREMENT," contain a .BZ archive (Avis_Virement1502002024.bz). Within the archive, Agent Tesla disguises itself as a fake document or notification of transfer of funds (Avis_Virement1502002024.exe). This is a run-of-the-mill social engineering tactic that's been used for years now and is still effective.

Agent Tesla goes after companies in Indonesia
Agent Tesla is one of the most prevalent stealers out there and has managed to maintain its position for years. It is used by multiple groups and individuals globally, conducting campaigns in numerous languages. Symantec has observed a new campaign targeting companies in Indonesia, particularly in the automotive, financial, oleochemical, electronic, and food sectors.
The actors behind this campaign do not employ strong social engineering tactics. Instead they rely on a common approach - the tax invoice.

Agent Tesla riding COVID spam wave
Agent Tesla is a sophisticated .Net keylogger and Remote Access Trojan (RAT) that was sold commercially. Because of its multi-functionality and easy-to-use nature, the malware has been one of the more popular tools used by cyber criminals and was employed in many attack campaigns throughout the years.
Recently Symantec observed Agent Tesla being delivered in an email attachment sent to more than 1,000 organizations around the globe. In order to maximize the chance of the recipients opening a malicious document file, the email has an enticing subject: "Re: Inquiry For 3ply Mask, Gown, Gloves and Goggles Offer". The email pretends to be a legitimate import-distributor company of basic chemicals and asks the recipient to open the attached document file to see quotes for those items which are closely associated with the current COVID-19 situation. Upon opening the document, an old vulnerability (CVE-2017-11882) in Microsoft Office is triggered. This vulnerability attracted public attention when a patch was finally provided for it in late 2017, given that the security hole had been left unpatched for a whopping 17 years. Successful exploitation leads to the download and execution of a remote file, namely, Agent Tesla. As Agent Tesla is a multi-purposed RAT, infection will bring a lot of problems to the targeted organizations.
CVE-2017-11882 is also known to be used to distribute other malware. Despite being 17 years late, don't forget to apply the patch!

Agent Tesla Targets Spanish Companies, Exfiltrating Data to Telegram
Symantec has recently observed an actor running a malspam campaign (email subject: FACTURA MES DE MARZO 2024) in Spain, purporting themselves as a Spanish company specializing in various accounting, tax, labor, and audit services for businesses. Recipients are being lured with an invoice scheme. If someone is tricked into opening the attached .GZ archive (Facturas Marzo.gz) and then running the malicious binary (Facturas Marzo.exe) within, they will end up compromised with Agent Tesla. Below are some of its stealing capabilities:
Log keystrokes
Steal web browser’s login credentials
Steal email server’s login credentials
Steal VPN passwords
Steal FTP server’s login credentials
Steal WinSCP’s login credentials
The malware is set up to communicate with a Telegram bot that the attacker controls. After collecting the stolen data and preparing it for transmission, the stealer utilizes the Telegram Bot API to send this information as messages to the attacker's Telegram account or group. It's a technique increasingly used by stealers and remote access trojan developers.

AgentTesla tries to sneak past the post undetected
Until a few decades ago, motor-racing teams were split into two categories in terms of measurements used to design racing cars, one with imperial units and the other using the newer metric system. With the success of the teams that measured parts using millimeter precision, the racing world gradually adopted the metric system.
Symantec recently observed AgentTesla being sent as an email attachment to companies spanning various industries. Among them, one spam message in particular caught our attention - an email sent to a well known motor-racing team about spare parts measured using the metric system. As the racing scheduled is tightly packed this year due to the ongoing pandemic, an unwary target might have opened the attachment with the blinding speed of a pitstop crew.

Agrius APT - using Ransomware as camouflage for their campaign of destruction
Ransomware is a lucrative business for cybercriminals but unfortunately it can also provide a means of camouflage to APT groups, allowing them to hide their true intentions behind financial gain and simple greed. In recent reports, a threat actor known as Agrius has moved away from being a plain wiper to a "Ransomware wiper" dubbed Apostle.
This group has targeted organizations in Israeli and the United Arab Emirates in cyber espionage and destruction campaigns. More recently they are leveraging exploits in web-based apps and SQL injection to gain initial entry into victims' infrastructure. From there, they use other tools such as Webshells and a backdoor known as "IPsec Helper" in the attack chain.

Ahmyth Android RAT continues to spy on mobile users
Ahmyth is an Android Remote Access Tool that's available on a well-known software development and version control platform. Over recent years, Ahmyth has been shared on hacker and underground forums, social network platforms and websites.
Through 2020 and into early 2021, we continued to observe Ahmyth activities as cybercriminals of various technical backgrounds first trialed and then added this RAT to their arsenals. As usual the most common vector has been to disguise Ahmyth as known Android applications related to companies and services, although there have also been instances where actors would trojanize legitimate applications with Ahmyth. These fake applications are then distributed via fake websites and social networks. In January 2021, researchers observed cybercriminals targeting users of a well known online European broker with this RAT.

AhRAT is an Android malware variant distributed in form of a trojanized Android app called "iRecorder – Screen Recorder". The app itself was first published back in 2021 and it did not include any malicious functionality initially. It seems the malicious code (based off another mobile malware known as AhMyth) has been added in some of the later updates around August 2022. The AhRAT malware has the functionality to collect microphone recordings, call logs, text messages, contact list and users' files from the compromised devices, among others.

AI tools used as lures for infostealers through Facebook Ads
With the current popularity of Large-Language-Models (LLMs) it is no surprise threat actors are using the trend as well to lure victims, in this case through paid Facebook Ads for AI tools and services. If the victim clicks on the ad, the threat actor will redirect traffic abusing legit URL redirection services to abused hosting and file sharing services to download a password protected archive. The password protection is done with the intent of avoiding detection by security programs, as it contains a Windows installer file inside. If the user continues, a fake browser extension will be installed through which the threat actor will try to syphon as much information from the victim as possible, especially anything related to Facebook.

Akira ransomware for Linux
Akira is a ransomware variant that first emerged on the threat landscape in April 2023. While initially only Windows variants of this ransomware have been observed, now also a Linux strain is available. The malware targets files with predetermined extensions for the encryption - many are related to virtualized VMware ESXi environments. After successful encryption, the malware will append .akira extension to the encrypted files and will drop the ransom notes onto the compromised system.

Akira ransomware remains an active threat on the landscape
Symantec Security Response is aware of the recent joint alert from CISA, the FBI, Europol's European Cybercrime Centre (EC3), and the Netherlands' National Cyber Security Centre (NCSC-NL) regarding a number of targeted activities observed for the Akira ransomware. Akira is a ransomware family seen on the threat landscape since at least 2023. According to the released report, Akira remains an active threat and has been leveraged in attacks on over 250 organizations to date. Initial C++based variants of Akira have been encrypting user files and appending .akira extension. Latest Rust-based variant called Megazord emerged last year and it is appending .powerranges extension to the encrypted files instead. Next to Windows-based Akira strain, the group behind this ransomware has also been known to distribute a Linux-based variant focused on VMware ESXi environments.

AKO ransomware malspam uptick
We have become aware of recent reports of AKO ransomware activities. This ransomware family was first discovered in January 2020 and is mainly distributed via malspam campaigns. Similar to other prevalent ransomware variants, besides encrypting user data AKO will also attempt to delete any backups and shadow volume copies it finds.
The malware drops a text ransom note named “ako-readme.txt” to several folders on the infected machine and a random extension gets appended to the names of the encrypted files. AKO is also capable of ping scans of networked machines that allows for further lateral movement into the infected network.
We recommend regular backup procedures of any important files and applying the latest product definitions to protect against the ransomware threat.

Albabat Ransomware (aka White Bat)
In recent weeks, Albabat Ransomware (also known as White Bat) has been observed making the rounds, targeting companies and consumers in various countries (e.g., Hungary, Kazakhstan, the US, Czech Republic, etc.). According to the observed binaries, the group seems to be using a fake Windows 10 digital activation tool to infect users.
Upon successful compromise, in addition to encrypting files, this ransomware leaves its mark by altering the machine's wallpaper (a white bat logo on a black background) and deploying a ransom note in HTML format.
The note contains detailed information about the group, explanations regarding the employed encryption method, contact details (a Proton mail email address), and instructions for ransom payment (a Bitcoin address and price). In recent activities, they were asking for 0.0015 Bitcoin (worth 67.87 USD at the time of writing). There is no explicit mention of double extortion in their ransom note, and victims are advised to reach out only if they are willing to comply with the ransom demands.

ALC ransomware
ALC is a ransomware variant that just recently appeared on the threat landscape. The malware acts more like a scareware since it does not really encrypt any files on the compromised system at this time but only enumerates them. This possibly indicates the ransomware might still be in the development phase. ALC drops an additional binary on the system named AlcDif.exe, which when executed displays the ransom note in full screen mode thus imitating a screen locker type of threat.

Almost 100 organizations in Brazil targeted with banking Trojan
Up to 100 organizations in Brazil have been targeted with a banking Trojan since approximately late August 2021, with the most recent activity seen in early October. The initial vector of these campaigns is likely a malicious URL spread via either spam email campaigns or through malvertising. Attacks consist of multiple stages of component downloads with the final payload being the banking Trojan. These downloads include a legitimate Oracle application which is used to execute the malicious banking Trojan file, mpr.dll, by way of DLL search order hijacking.

Alpha Ransomware
Alpha, a new ransomware that first appeared in February 2023 and stepped up its operations in recent weeks, has strong similarities to the long defunct NetWalker ransomware, which disappeared in January 2021 following an international law enforcement operation. Both threats use a similar PowerShell-based loader to deliver the payload. In addition to this, there is a significant amount of code overlap between the Alpha and NetWalker payloads. While Alpha first appeared in February 2023, it maintained a low profile until recent weeks when it appeared to begin scaling up its operations and launching a data leak site.

Alpine bank users credentials at risk of smishing attack
Symantec has recently observed a smishing campaign targeting customers of Alpine Bank - a community bank based in Colorado, USA. They operate in various cities and towns across the state and are known for their focus on community involvement and customer service, with the attackers hoping to snatch their credentials.
The individuals or groups behind this attack have sent malicious messages to mobile users, informing them that their debit card has been locked following suspicious activities, and inviting them to click on the provided URL. While this type of social engineering tactic is prevalent worldwide, seasoned actors usually engage in domain typo-squatting to increase their chances of tricking users. In this instance however, the crooks have simply created a fake Alpine Bank login page for a domain that is clearly not similar to Alpine Bank's domain.

Amadey Botnet Activities continue
The Amadey botnet is still active and we continue to observe new attacks. Having been sold on the black market since at least 2018, multiple groups and individuals have purchased its services to distribute their payloads. A notorious group known as TA505 has even used the Amadey botnet to deliver a remote access Trojan (RAT) called FlawedAmmyy.
The group behind this malware and their customers have employed various infection vectors including Exploit kits such as RIG and Fallout, as well as email spam runs in order to infect even more machines. It should be noted that the authors constantly push out new versions (up to at least v1.99 at the time of this writing) with recent samples compiled using MINGW32.
Currently, Amadey is capable of downloading custom payloads and attempts to steal host, username and password information from the following applications on victim machines:
filezilla

wcx_ftp
realvnc
tightvnc

Recently, a group of researchers discovered a multi-stage PowerShell attack delivered via a malicious PDF document file that masquerades as Kazakh Ministry of Health Care. Last November 8, an individual named 'DangerSklif' uploaded the first part of the attack via Github.
The attack will commence from a LNK file, and upon execution the file opens up a PDF file as a decoy while simultaneously running a PowerShell outlined to perform several techniques such as privilege escalation and persistency through an autorun registry key. The attack by design will take a few more other steps to stay under the radar in an attempt to increase the likelihood of deploying Cobalt Strike on to its targets.

Android Locker via fake documents
While ransomware is wreaking havoc in the desktop landscape, Symantec continues to see Android Locker targeting mobile users, although it is far less prevalent than it was a couple of years ago. In a recent example, we observed Malaysian actors posing their locker as fake documents (DOC-[date]-[random characters].apk). On top of being able to lock one's Android phone screen, it is also capable of collecting sensitive data such as device information, SMS messages, contacts, and camera data. Victims are prompted via a new wallpaper set by the actor to connect through Telegram and pay the ransom in exchange for the unlock code.

A new version of a banking Trojan known as Mekotio
Mekotio, a modular banking Trojan, primarily targets Latin American countries. The start of the infection chain uses phishing emails with claims of a tax receipt pending submission. The message, containing a link to a ZIP or a ZIP attachment, lures the victim to download and extract the ZIP content. The ZIP contains an obfuscated batch script that fetches and executes a PowerShell script. Once the PowerShell script gets launched, it will download a second ZIP archive after some basic checks against location and anti-analysis techniques. The second ZIP, which contains the Mekotio payload in DLL form, is extracted. Mekotio's primary goal is to obtain e-banking credentials and online account passwords from infected victim machines. The exfiltrated data is sent to the C2 server.

Apple Pay smishing campaign hits mobile users
Over the past year, phishing via Short Message Service (SMS) has steadily increased in activity - these attacks are also known as "smishing" in the cybersecurity world. Most of these campaigns lead to fake websites where victims are lured to input their credentials but there have also been instances where these websites would draw them into installing a mobile malware. When it comes to credential phishing, actors primarily purport themselves as services linked to finances such as banks. Recently, there was a campaign targeting Apple users where the victim would receive an SMS saying their Apple Pay has been temporarily suspended, asking them to visit a website to confirm details. If successfully tricked into doing so, the fake website will then attempt to phish the user's financial information.
