A new phishing campaign unveiled by researchers from DomainTools is a phishing campaign on the go, deceiving users via fake text messages. The messages masquerade as trusted brands like Amazon to get the targets to give away sensitive data. This operation is put at the hands of the threat actor "Chenlun," who was seen tricking people last year for masquerading as a USPS delivery alert during the holiday season. On 18 October 2024, consumer targeting waves, this wave represents new waves in tactics that target trusting consumers on the most-used brands.
Phishing Attack Evolution: From USPS Notification Scam to Authentication and Authorization Hack
In December 2023, DomainTools reported on the earlier approach that Chenlun used through exploiting USPS alerts to instruct users on how to navigate to fraudulent websites. This scheme, also labelled as "smishing, tricked users into message prompting them to visit virtually identical websites to the one genuine USPS websites. These next sent information that victims did not need to provide. With the current attack, however, Chenlun used the more narrow deception of alerts that there is unauthorised access to his or her online store accounts. This prompted victims into confirmation of their account information with links that led him to a scam website. To this end, it goes without saying that one ought to be careful when opening any link on email or text.
Advanced techniques of hiding and concealing evidence
The strategies that Chenlun uses today are more advanced than that of not being detected. The phishing attack this year is different from the past years because it does not use domain names containing USPS but instead uses a DGA. A DGA automatically generates new, arbitrary domain names, which creates an added difficulty in blocking malicious websites and makes it challenging for the security systems to identify phishing attempts. The constant change in the infrastructure of the domain leaves Chenlun free to continue their attacks without instant interference from cybersecurity defences.
Changed Domain Structures and Aliases
The latest phishing campaign also demonstrates the changed structure of the Chenlun domain. Last year, the fraudsters utilised domains like the official USPS websites. This time around, they change them into simple domains and even switch to other registrars and name servers. Now, they use NameSilo and DNSOwl, for example, and not Alibaba Cloud's DNS service, just like last year. The changing tendency makes phishing attempts less predictable and also complicates the procedure for cybersecurity analysts in relation to the identification and monitoring of suspicious domains.
Moreover, the most recent activity of Chenlun used pseudonyms like "Matt Kikabi" and "Mate Kika". These pseudonyms, which were first identified in the 2023 report, have more than 700 active domains. Reusing these identities, Chenlun has been able to maintain a massive presence online undetected by cybersecurity tools.
Collaboration as a Critical Form of Defense Against Phishing
DomainTools emphasises that effective countermeasures against phishing attacks require the collective efforts of organisations. Recommendations from security experts include active monitoring of registration patterns, sharing threat intelligence, and developing robust strategies that can counter changing phishing techniques.
DomainTools further emphasises that Chenlun's strategy changes reflect the ongoing problem that cybersecurity professionals face. By constantly changing obfuscation techniques, Chenlun underlines the importance of domain-related data in identifying patterns and suspect domains.
Takeaway for Business and Consumers
Continuous activity by Chenlun also points to the fact that vigilance needs to be maintained, given the sophistication in phishing scams. Business entities need to strengthen cybersecurity measures in monitoring domain registrations and promote threat intelligence sharing. Individual consumers need to maintain vigilance by avoiding a response to unsolicited messages or links.
In short, Chenlun's latest phishing campaign calls out for proactive defence. While the attackers continue adapting with a view to remain unseen, the necessity for people to stay updated and network inter-sectorally is the urgent requirement in the world of digitization.
The campaigns involve exploiting cloud storage platforms such as Amazon S3, Google Cloud Storage, Backblaze B2, and IBM Cloud Object Storage. Unnamed threat actors are behind these campaigns. Their primary goal is to redirect users to malicious websites using SMS messages.
Bypassing Network Firewalls: First, they want to ensure that scam text messages reach mobile handsets without being detected by network firewalls. Second, they attempt to persuade end users that the communications or links they receive are legitimate.
Building Trust: They aim to convince end users that the messages or links they receive are trustworthy. By using cloud storage systems to host static websites with embedded spam URLs, attackers can make their messages appear authentic while avoiding typical security safeguards.
Cloud storage services enable enterprises to store and manage files and host static websites by storing website components in storage buckets. Cybercriminals have used this capacity to inject spam URLs into static websites hosted on these platforms.
They send URLs referring to these cloud storage sites by SMS, which frequently avoids firewall limitations due to the apparent authenticity of well-known cloud domains. Users who click on these links are unknowingly sent to dangerous websites.
For example, attackers utilized the Google Cloud Storage domain "storage.googleapis.com" to generate URLs that lead to spam sites. The static webpage housed in a Google Cloud bucket uses HTML meta-refresh techniques to route readers to fraud sites right away. This strategy enables fraudsters to lead customers to fraudulent websites that frequently replicate real offerings, such as gift card promotions, to obtain personal and financial information.
Enea has also detected similar approaches with other cloud storage platforms like Amazon Web (AWS) and IBM Cloud, in which URLs in SMS messages redirect to static websites hosting spam.
To protect against such risks, Enea advised monitoring traffic activity, checking URLs, and being cautious of unexpected communications including links.
Given a recent incident reported by The Cut, freelance finance writer Charlotte Cowles fell victim to an elaborate scam that highlights the dangers of social engineering. The scam began with a call from a number appearing as "Amazon," leading Cowles to believe she was a victim of identity theft. The caller, posing as a Federal Trade Commission official, connected her with a fake CIA agent named Michael. Over hours on the phone, "Michael" convinced Cowles that she faced serious charges related to the identity theft and persuaded her to withdraw $50,000 in cash. The twist? She was instructed to hand over the money to the CIA, which would inexplicably issue her a check for her own funds.
Despite suspicions during the ordeal, the scammers manipulated Cowles into isolation, urging her not to involve her family or the police, claiming it could jeopardise their safety. This tactic of isolating the victim is a common element in scams, aiming to heighten emotions and push individuals into making decisions they might not otherwise make. The scammers played on Cowles' fears for herself and her family, using personal details like the last four digits of her Social Security number to further erode her judgement.
Experts emphasise that falling victim to professional scammers is not a matter of lacking savvy. Selena Larson, a senior threat intelligence analyst, stresses that fraud perpetrators excel at social engineering and employ tactics like instilling fear, excitement, or urgency to manipulate their targets. To protect against such scams, Larson advises people to be wary of anyone trying to isolate them from friends and family, cautioning against trusting individuals posing as government officials or celebrities. Immediate requests for money and a sense of urgency are red flags that should prompt individuals to break off contact and report the activity.
This cautionary tale serves as a reminder that anyone can be targeted by scams. Larson suggests a vigilant approach, emphasising the importance of staying connected with loved ones and not succumbing to isolation. Additionally, adopting a strategy similar to Cowles' newfound tactic—never answering calls from unknown numbers—can be an effective way to avoid falling prey to scams.
As online threats continue to multiply, it is crucial for individuals to remain informed and alert. The incident also borders on the broader issue of cyber threats, including state-backed hacking efforts, ransomware attacks on hospitals, and the impact of cyberattacks on vulnerable communities. Stay safe and informed as we venture through the complexities of online security.
At a meeting with European Commission officials on Thursday, the e-commerce behemoth was informed that the transaction would probably be denied, according to sources familiar with the situation. The political leadership of the EU must still formally approve a final decision, which is required by February 14. Meanwhile, Amazon declined to comment on the issue.
On Friday, iRobot’s shares, based in Bedford, Massachusetts, fell as much as 31% to $16.30, expanding the deal spread to over $35, the greatest since the merger was disclosed more than a year ago.
Regulators believe that other vacuum manufacturers may find it more difficult to compete as a result of iRobot's partnership with Amazon, particularly if Amazon decides to give Roomba advantages over competitors on its online store.
There will probably be opposition to the deal in the US as well. People with an insight into the situation claim that the Federal Trade Commission has been preparing a lawsuit to try and stop the transaction. According to persons speaking about an ongoing investigation, the three FTC commissioners have yet to vote on a challenge or hold a final meeting with Amazon to discuss the possible case.
The investigation over Amazon’s acquisition of iRobot was initiated in July 2023 by the European Commission (EC), the EU’s competition watchdog.
The EC has until February 14 to make a decision. The commission's 27 most powerful political members must agree to reject the proposal before the EC can make a final decision.
While iRobot was all set to expand its business in the market of smart home appliances, it witnessed a 40% dip in its shares a few hours after the first reporting of the EU’s intentions in the Wall Street Journal.
Given that the company has been struggling with declining revenues, the acquisition by Amazon was initially viewed as a boon.
In regards to the situation, Matt Schruers, president of tech lobbying group Computer and Communications Industry Association comments that "If the objective is to have more competition in the home robotics sector, this makes no sense[…]Blocking this deal may well leave consumers with fewer options, and regulators cannot sweep that fact under the rug."
According to Damian Williams, the U.S. attorney for the Southern District of New York, this was the second case their firm was announcing that is highlighting the case of “fraud in the cryptocurrency and digital asset ecosystem.”
As noted by the DOJ, Ahmed – a former security engineer for an “international technology company” – was able to "fraudulently obtain" from the aforementioned exchange almost $9 million worth of cryptocurrencies. He executed this by creating bogus dates for pricing, in order to produce the fees that he later withdrew for himself.
Williams further added, "We also allege that he then laundered the stolen funds through a series of complex transfers on the blockchain where he swapped cryptocurrencies, hopped across different crypto blockchains, and used overseas crypto exchanges. But none of those actions covered the defendant's tracks or fooled law enforcement, and they certainly didn't stop my Office or our law enforcement partners from following the money."
Ahmed is also charged with allegedly attempting to steal more money from the exchange via "flash loan" attacks, another type of crypto vulnerability
While it was initially imprecise as to what company the accused had worked for, cybersecurity blogger Jackie Singh on Tuesday mentioned that Ahmed was a former Amazon employee. Jackie further mentioned several other online profiles the accused appeared to have links with.
According to a LinkedIn profile that matches Ahmed's job description, he works at Amazon as a "Senior Security Engineer" and has worked there since November 2020. The user's profile continues to claim Amazon as his employer. However, it is still unclear if this profile is in fact representing Ahmed.
Following this, Amazon was contacted to confirm the aforementioned details, to which the company confirmed that he had worked for Amazon. However he is no longer employed with the company, they added. The tech giant said that it could not provide any further information regarding his role in the company.
Moreover, a report by Inner City Press – a New York outlet – confirms that Ahmed appeared at the court following his detainment on Tuesday. The report mentions him wearing flip-flops, shorts, and a T-shirt saying “I code,” to the court hearing. Later, he was released on bond after pleading not guilty and will be permitted to continue living in his Manhattan apartment, according to the site.
