A round up of some of the phishing campaigns and phishing tactics identified over the past few days in campaigns targeting businesses in the banking and IT sectors, and individuals seeking unemployment benefits.
Fake Google ReCAPTCHA Used in Ongoing Phishing Campaigns
The use of CAPTCHA, an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart”, is now common in phishing campaigns. CAPTCHA involves an image test, such as identifying all images in a group that contain cars, a test to identify characters in a slightly obfuscated image, or simply confirming that “I am not a robot.”
The Google reCAPTCHA is used on websites to distinguish human traffic from machines to protect against abusive activities by malicious code and software. ReCAPTCHA is a sign of security and the use of this system on a website helps to inspire trust. That trust is being abused by cybercriminals who have added fake Google ReCAPTCHAs to phishing sites. This tactic is becoming much more common.
One recently identified campaign uses emails with a message about a voicemail message that impersonate company communication tools. The attachment directs the user to a phishing website where they are presented with a CAPTCHA challenge. In this campaign, the user must complete the standard ‘I am not a robot’ challenge and will then be presented with a Microsoft 365 login prompt. In addition to using Microsoft logos, the corporate logo of the company being targeted is also included. When credentials are entered, the user is told they have successfully validated and will proceed to a generic voicemail message. The lures used in these campaigns change frequently, with requests to review documents also common.
This campaigns targets business executives in the banking and IT sectors, although the same tactic has been used throughout 2020 on targets in other industry sectors.
NFA Impersonated in Phishing Campaign Targeting Member Firms
A phishing campaign has been detected targeting the financial industry which impersonates the National Futures Association (NFA). The tactics used in this campaign are common in phishing scams – Impersonating a trusted entity and abusing that trust to get individuals to install malware.
The emails in this campaign have been sent from an email address on a domain that closely resembles the legitimate NFA domain. The official NFA domain is nfa.futures.org, whereas the phishing emails have been sent from the domain nfa-futures[.]org.
The emails appear to have been sent by legitimate NFA staff members, with the signature including their name, job title, and the correct address of the office, with fake phone numbers. The signature of the email lists two websites: The official domain and also the fake domain.
As with many phishing campaigns, the recipient is told urgent action must be taken. The message says the NFA has made many attempts to contact the recipient about a matter that requires an urgent response. These emails are being used to direct individuals to malicious website or convince them to open malicious attachments with the aim of delivering malware.
Phishing Campaign Impersonates State Workforce Agencies Offering Unemployment Benefits
Cybercriminals are creating fake websites that mimic genuine state workforce agencies (SWAs) in the United States in order to steal sensitive personal information that can be used for identity theft and fraud. The tactics are similar to the above campaign, although the aim is to obtain sensitive information rather than install malware on a business network.
The state workforce agency websites that the malicious sites impersonate are used by individuals to apply for unemployment benefits. In order to receive those benefits, individuals must provide personally identifiable information. Campaigns are being conducted to impersonate these sites and trick people into believing they are on the genuine website. After landing on the malicious page, a series of questions must be answered as part of a fake application for unemployment insurance benefits.
Traffic to the fake unemployment benefit websites is generated through phishing emails and text messages that impersonate an SWA, encouraging recipients to apply for benefits. These messages have been created to closely resemble official communications, using the official logos and color schemes of each SWA, with the domain linked in the email closely resembling the official SWA website.
Solutions to Improve Defenses Against Phishing Attacks
Phishing attacks are often sophisticated and highly targeted, and tactics, techniques, and procedures continually change to bypass technical and human defenses. To stay one step ahead of the scammers, businesses need to adopt a defense in depth approach to cybersecurity and implement multiple overlapping layers of security to block threats. If phishers and hackers manage to bypass one layer of security defenses, others will be in place to provide protection.
Human defenses, such as training the workforce how to identify phishing emails is important. When a threat is encountered, employees will know how to react. It is also possible to condition employees not to take risks, such as opening emails attachments in unsolicited messages from unknown senders. The sophistication of campaigns, spoofing of email addresses, lookalike domains, and email impersonation tactics make it difficult for some phishing emails to be distinguished from genuine email communications.
Technical defenses will ensure most threats are blocked and do not reach inboxes. An email security gateway solution is a must and should also be used on Office 365 environments. The standard Office 365 spam filter is simply not good enough at blocking threats. Spam filters with machine learning capabilities and greylisting will help to ensure more threats are blocked, and multiple malware detection methods should be used, including sandboxing to detect new malware threats. A web filter should also be considered for blocking the web-based component of phishing attacks. A web filter will provide time-of click protection and prevent individuals from visiting malicious sites and downloading potentially malicious files.
