WithSecure security researchers have discovered a novel cybercrime strategy that specifically targets users of LinkedIn.
Malware is being distributed by a Vietnamese cybercrime syndicate via phony employment opportunities that have been posted on a well-known professional networking platform. Social media management personnel situated in the United States, United Kingdom, and India are the most significantly impacted.
The perpetrators impersonate Facebook Ads specialists employed by Corsair, a company specializing in gaming accessories and computer memory, in order to trick unsuspecting users into downloading a password-protected ZIP archive.
The DarkGate malware, which, upon unzipping, is designed to obtain elevated privileges to the Facebook accounts of organizations so that cybercriminals may exploit them for ad campaigns on the platform, is released. Particularly on work devices, this article emphasizes the significance of employee training and exercising caution when opening suspicious files.
In review,
This article aims to provide a thorough analysis of the phishing campaign that exploits LinkedIn users by presenting a forged employment opportunity at Corsair. The DarkGate malware is being employed by the perpetrators of this scheme in order to compromise the computers of the victims and obtain illicit access to their Facebook accounts. The targeted platform, the malware employed, and the victim profiles will be investigated.
An exposition of the matter at hand
Recently, WithSecure security researchers identified a concerning trend on LinkedIn: the publication of bogus employment opportunities by cybercriminals. The job advertisements are designed to attract candidates who are currently employed in social media management positions. The assailants adopt the personas of representatives from the renowned computer memory and gaming accessories company Corsair, asserting that they are in the process of recruiting a Facebook Ads specialist. Yet, concealed within these ostensibly authentic employment advertisements conceals a perilous cyber menace.
The intended platform
LinkedIn has been selected as the preferred platform by the cybercriminals to execute this malware campaign. LinkedIn is an international professional networking platform that links millions of professionals. The malevolent scheme seeks to delude unsuspecting job seekers by capitalizing on the credibility and trustworthiness that are inherent in LinkedIn.
Malware implementation
DarkGate is the malware utilized in this phishing campaign. Once DarkGate obtains access to a victim’s computer, it is able to carry out a variety of malicious activities, making it a dangerous and sophisticated piece of malware. This encompasses activities such as unauthorized downloads, theft of sensitive data, and even disabling security products.
The victim’s profile
Individuals occupying social media management positions and residing in the United States, United Kingdom, and India are the principal targets of this phishing campaign. Given the likelihood that these professionals utilize LinkedIn frequently, they are susceptible to this scheme. Through the process of refining their victim profile, cybercriminals can increase the likelihood of successfully infecting unsuspecting individuals.
Details-Based Attack Modus Operandi
The perpetrators initiate their scheme by publishing fraudulent employment prospects on LinkedIn, with a particular focus on individuals engaged in social media management. According to the job postings, Corsair, a reputable manufacturer of gaming accessories and computer memory, is seeking a Facebook Ads specialist. Through the provision of an apparently alluring employment opportunity, cybercriminals entice individuals seeking employment to participate in their fraudulent scheme.
Component files of the archive
After registering for the illegitimate employment opportunity, the user is redirected to a password-protected ZIP archive. The archive comprises multiple files, such as a PDF document that provides additional information regarding the salary and products, a text file that mentions remuneration, and a job description document that includes a reference to new products. Unbeknownst to the unsuspecting victim, they are accessing legitimate information when, in fact, they are being duped.
Conducting the DarkGate malware attack
As soon as the ZIP archive’s contents are extracted, the DarkGate malware infects the victim’s system. A series of malicious activities are initiated by the malware, which includes the acquisition of additional code from the internet. DarkGate attempts to deactivate any pre-existing security products from the victim’s computer within thirty seconds of installation, thereby leaving the device susceptible to subsequent assaults.
The principal aim of the assault
The primary aim of the DarkGate malware assault is to acquire elevated privileges to the Facebook accounts of the targeted individuals. Cybercriminals can exploit the businesses affiliated with these compromised accounts through the dissemination of fraudulent advertising campaigns on the social networking platform. Unauthorized access has the potential to result in substantial financial losses and reputational harm to the affected enterprises.
‘Ducktail’ was a prior cybercrime committed by the Gang Hacking operation.
The group responsible for conducting this phishing campaign has an established track record of engaging in cybercriminal schemes. Significantly, they had prior experience participating in a cyber campaign called ‘Ducktail.’ The crew was able to pilfer up to $600,000 in advertising credits from compromised Facebook Business accounts during this operation. The cybercriminal organization’s sophistication and audacity are exemplified by the success of ‘Ducktail’.
Theft of promotional rewards
The cybercriminal cell exploited Facebook Business accounts for financial benefit as part of the ‘Ducktail’ operation. They were able to utilize the funds obtained from the theft of advertising credits to finance their own deceitful endeavors, thereby causing significant repercussions for the victims and the online advertising sector at large. The affected businesses incurred a substantial financial loss due to the pilfered funds.
Consequences of the prior assault
The preceding assault executed by this cybercriminal syndicate underscores the gravity of their endeavors and the possible consequences that may befall their prey. In addition to the immediate monetary setbacks, compromised accounts can result in reputational harm, erosion of consumer confidence, and legal ramifications for organizations. It is critical to prevent future assaults by applying the necessary precautions and gaining insight from these past incidents.
The Value of Employee Training
Dangers associated with accessing suspicious files
Training personnel to recognize and respond to suspicious files is a critical aspect that has been underscored by this phishing campaign. The cybercriminals exploited the zeal of job candidates to investigate novel prospects, which resulted in their decryption of the malicious ZIP archive. Organizations can substantially mitigate the likelihood of succumbing to such assaults by safeguarding their personnel from the perils associated with opening dubious files.
Seeking employment opportunities
An additional crucial element that warrants attention is the potential hazard linked to conducting job search activities on the computers of an incumbent employer. Many job candidates may be unaware that their employer’s network is equipped with security measures that filter and monitor internet activity. Through the use of work computers to conduct job searches, individuals may unintentionally subject both themselves and their employer to cyber hazards. One way to mitigate this risk is by promoting the use of personal devices for job searches among employees.
Utilizing the workplace device
In a similar vein, the use of computers provided by an employer for personal purposes, including interaction with social media platforms, introduces a distinct array of difficulties. Given the context, LinkedIn, which was utilized for professional networking, was the intended platform. Employees may unintentionally compromise corporate security by surfing social media on work laptops. work employees must be warned against utilizing work computers for personal use.
Preventive actions
Organizations must adopt preventive measures in order to mitigate the likelihood of succumbing to phishing campaigns and malware attacks. These encompass extensive staff training initiatives that impart knowledge to personnel regarding the most recent cyber threats, periodic security awareness campaigns, and stringent access regulations to sensitive systems. Through the implementation of a proactive cybersecurity strategy, organizations can substantially mitigate their susceptibility to such breaches.
