Fraudulent UK Visa Scams Circulate on WhatsApp


According to a Malwarebytes report, individuals working in the UK are being scammed by a recent phishing campaign on WhatsApp. 

Scammers claim in a WhatsApp message that users who are willing to relocate to the UK for work will be eligible for a free visa as well as other perks. 

Bogus scam message 

Scam operators are disseminating information under the pretext of the UK government, promising a free visa and other advantages to anyone who wants to migrate there. The chosen candidates would be given travel and lodging expenses as well as access to medical facilities. 

The WhatsApp chat app is used to transmit to target volumes to start the fraud. Users are informed that the UK is conducting a recruiting drive with more than 186,000 open job positions because the country will require more than 132,000 additional workers by the year 2022. 

The objective of the scam 

When a victim clicks on the scam link, a malicious domain that looks like a website for UK Visas and Immigration is displayed to them. "Apply for thousands of jobs already available in the United Kingdom," is the request made to foreign nationals as per the scam.

The website's goal is to collect victims' names, email addresses, phone numbers, marital statuses, and employment statuses. 

Any information entered into the free application form is instantly 'accepted,' and the user is informed that they "will be provided a work permit, visa, plane tickets, and housing in the UK for free" according to a Malwarebytes report. 


Report fake WhatsApp messages

Users have the option to Report and Block on WhatsApp if they get a message from someone who is not on their contact list. One should disregard these spam communications and use the report button to file a complaint. Additionally, users can block these contacts in order to stop getting future scam messages from them.

Phishing attacks with a Visa theme are a typical occurrence in the world of cybercriminals. A similar hoax circulated several times in the past to entice people looking to work or study abroad.


Security Researchers Discovered Crimea Manifesto Buried in VBA Rat

 

On Thursday, Hossein Jazi and the Threat Intelligence team at Malwarebytes released a report revealing a new threat actor that may be targeting Russian and pro-Russian individuals. A manifesto regarding Crimea was included by the assailants, implying that the attack was politically motivated. A suspicious document called "Manifest.docx" is used in the attacks, and it downloads and runs two attack vectors: remote template injection and CVE-2021-26411, an Internet Explorer exploit. Malwarebytes' Threat Intelligence team discovered the "Манифест.docx" ("Manifest.docx") on July 21.

"Both techniques have been loaded by malicious documents using the template injection technique. The first template contains a url to download a remote template that has an embedded full-featured VBA Rat. This Rat has several different capabilities including downloading, uploading, and executing files," Jazi said. 

The second template is imported into the document and is included in Document.xml.rels. According to the threat research teams at Google and Microsoft, the loaded code contains an IE Exploit (CVE-2021-26411) that was previously utilized by Lazarus APT to target security researchers working on vulnerability disclosure. The shell code used in this vulnerability loads the same VBA Rat as the remote template injection exploit. 

The attack, according to Jazi, was motivated by the ongoing conflict between Russia and Ukraine, which includes Crimea. Cyberattacks on both sides have been on the rise, according to the report. The manifesto and Crimea information, however, might be utilized as a false flag by threat actors, according to Jazi. 

The attackers used a combination of social engineering and the exploit, according to the report, to boost their chances of infecting victims. Malwarebytes was unable to pin the assault on a single actor but said that victims were shown a decoy document with a statement from a group linked to a figure named Andrey Sergeevich Portyko, who supposedly opposes Russian President Vladimir Putin's Crimean Peninsula policies. 

The decoy document is loaded after the remote templates, according to Jazi. The document is written in Russian but also has an English translation. A VBA Rat is also included in the attack, which collects victim information, identifies the AV product installed on the victim's workstation, runs shell-codes, deletes files, uploads and downloads files, and reads disc and file system information. Instead of using well-known API calls for shell code execution, which can easily be flagged by AV products, the threat actor employed the unique EnumWindows to run its shell-code, according to Jazi.

New Malware Downloader Spotted in Targeted Campaigns

 

In recent weeks, a relatively sophisticated new malware downloader has emerged that, while not widely distributed yet, appears to be gaining momentum. Malwarebytes researchers recently discovered the Saint Bot dropper, as they have termed it, being used as part of the infection chain in targeted campaigns against government institutions in Georgia. 

Saint Bot was discovered by researchers while investigating a phishing email containing a zip file containing malware they had never seen before. The zip file included an obfuscated PowerShell script disguised as a link to a Bitcoin wallet. According to Malwarebytes, the script started a chain of infections that led to Saint Bot being dropped on the compromised system. 

In each case, the attackers used Saint Bot to drop information stealers and other malware downloaders. According to the security vendor, the new loader is probably being used by a few different threat actors, implying that there are likely other victims. 

One of the information stealers that Saint Bot has noticed dropping is Taurus, a malware tool designed to steal passwords, browser history, cookies, and data from auto-fill. The Taurus stealer can also steal FTP and email client credentials, as well as system information such as configuration details and installed software. According to Malwarebytes, while Saint Bot mostly has been observed dropping stealers, the dropper is designed to deliver any malware on a compromised system. 

Malware droppers are specialized tools designed to install various types of malware on victim systems. One of the most notable recent examples of such malware is Sunburst, the tool that was distributed via poisoned SolarWinds Orion software updates to some 18,000 organizations worldwide. In that case, the dropper was specifically designed to deliver targeted payloads on systems belonging to organizations of particular interest to the attackers. 

Basically, the downloaders are first-stage malware tools designed to deliver a wide range of secondary and tertiary commodity payloads, such as ransomware, banking Trojans, cryptominers, and other malicious tools. Some of the most popular droppers in recent years, such as Emotet, Trickbot, and Dridex, began as banking Trojans before their operators switched tactics and used their Trojans as malware-delivery vehicles for other criminals. 

Saint Bot, like many other droppers, has several unclear and anti-analysis features to help it avoid malware detection tools. It is designed to detect virtual machines and, in some cases, to detect but not execute on systems located in specific Commonwealth of Independent States countries, which include former Soviet bloc countries such as Russia, Azerbaijan, Armenia, Uzbekistan, Ukraine, and Moldova.

"As we were about to publish on this downloader, we identified a few new campaigns that appear to be politically motivated and where Saint Bot was being used as part of the infection chain. In particular, we observed malicious documents laced with exploits often accompanied by decoy files." a spokesman from Malwarebytes' threat intelligence team states. In all instances, Saint Bot was eventually used to drop stealers. 

According to Malwarebytes, while Saint Bot is not yet a widespread threat, there are indications that the malware's creators are still actively working on it. According to the security vendor, its investigation of the Saint Bot reveals that a previous version of the tool existed not long ago. " Additionally, we are also seeing new campaigns that appear to be from different customers, which would indicate that the malware author is involved in further customizing the product," a Malwarebytes spokesman said.

Malwarebytes Report Confirms the Change in Tactics of Cybercriminals During Covid-19

 

Malwarebytes, an American security firm announced the findings of its annual ‘State of Malware’ report, this report explored the working methodology of employees and cybercriminals. Work from home was the new normal during the Covid-19 pandemic wherein many companies altered their working methodology and started working remotely.

The notable change was in the working methodology of the threat actors, they were more focused on gathering intelligence, and exploiting and preying upon fears with targeted and sophisticated assaults. Last year, threat actors targeted many high-profile firms and popular personalities which included hacking the accounts of famous personalities such as Barack Obama, Jeff Bezos, and Elon Musk; attacking FireEye and SolarWinds via supply chain and the Marriott hotel which recorded theft of the records of 5.2 million guests.

Marcin Kleczynski, CEO of Malwarebytes stated, “this past year has taught us that cybercriminals are increasingly formidable, planning long-term, strategic, and focused attacks that are sometimes years in the making. 2020 continued to show us that no company is immune, and there is no such thing as ‘safe enough’.”

“The COVID-19 pandemic compounded this with new challenges in securing remote workforces, making it essential that we quickly become more adaptable and learn how to better protect workers in any environment. While our total detections are down this year, we must remain vigilant. The threats we are seeing are more refined and damaging than ever before”, he further added.

Last year, Malwarebytes observed an overall drop of 24 percent of Windows detections across businesses and an 11 percent drop for clients. In total, there was a 12 percent drop in Windows detections across the board. However, Mac detections for businesses surged to 31 percent, 2020 also witnessed the growth of Android malware called FakeAdsBlock, which produced an alarming number of non-stop ads, accounting for 80,654 detections.

HiddenAds was discovered to be the most common mobile adware application, this trojan attacks users with ads, and nearly 704,418 malicious activities were reported with an increase of nearly 150 percent year-over-year.

Software companies have been serving the general public for years. But in this process, starts the raging war between the companies and the so-called "crackers" who try to counterfeit genuine products in order to promote piracy.

This creates a loophole in the distribution part of the products. This battle has seen some technical advancement in preventing counterfeiting of the services.

While Microsoft has implemented a product activation procedure for the Windows Operating system and its Office suite, some of the premiere gaming company have a registration process into their servers in order to activate the game, declining which the game becomes unavailable for playing. Yet, there is a continuous struggle amongst the "cracking " society to crack the softwares for free access and piracy.

While this struggle has accelerated with time, a company has finally decided to allow the vicious pirates to gain legit access to their product. Malwarebytes, a premium security firm has initiated Amnesty, a program to enable the users who have procured the serial key from piracy dealers or have downloaded it from the internet, to reissue their security key for free. This reissued key will provide the user with premium access to Malwarebytes Anti-Malware for a period of 12-months.

The company states that the internet has good pioneers as well as bad pirates. While the pioneers work hard day and night in order to provide users with state of the art services, pirates try to dupe people into buying pirated versions of Malwarebytes Anti-Malware.

"Amnesty program has initiated providing free replacement keys to the premium customers who have been facing inconvenience because of pirated keys or software abuse for Malwarebytes Anti-Malware".
