[Eye Opener] So, Your MFA Is Phishable, What to Do Next?
We've written a lot about multi-factor authentication (MFA) not being the Holy Grail to prevent phishing attacks, we also have an eBook on the subject, and we have several webinars on the subject including a very recent one. (links to blog below)
Most MFA is Easily Phishable
Many people are shocked when we show them how easy it is to bypass or hack most MFA solutions. In the majority of cases, it's as easy to do as phishing a password. On the blog we have a good example video demonstrating how easy it is to phish past most MFA solutions.
Use Phishing-Resistant MFA When You Can
So, our advice is to use PHISHING-RESISTANT MFA and not just ANY MFA, whenever possible. Actually, it's not just our advice. The U.S. government has been saying not to use easily phishable MFA at least since 2017. Presidential executive orders in 2021 and 2022 have again reinforced the idea that no one should be using easily phishable MFA.
Despite this, perhaps 90% to 95% of the MFA used by most people today is easily phishable. Well, the ultimate solution is to upgrade or move to phishing-resistant MFA when you can. Knowbe4's Data-Driven Defense Evangelist, Roger A. Grimes, keeps an up-to-date list of every MFA solution and type he is aware of that is phishing-resistant. Use one of those phishing-resistant MFA solutions if you can.
But if you already have a phishable MFA solution, most of the time it is not easy to replace or change to a phishing resistant form. You have what you have. Or what you use is forced upon you by a vendor or service you want to do business with. Much of the time when you have phishable MFA you can't easily upgrade or replace.
What to Do? So, what's a person or organization supposed to do if they have easily phishable MFA and can't simply change it?
No matter what type of MFA solution you have or use, easily phishable or not, there are ways to hack and get around it. Nothing is unhackable, not even the strongest, most secure form of MFA. So, the solution is to educate yourself and all other stakeholders, especially end-users, about the following topics:
- How to correctly use the MFA solution
- Strengths and weaknesses of the MFA solution
- The common possible attacks for that type of MFA and how to detect and prevent
- What to do during rogue hacking attempts (i.e., defeat and report it)
- What MFA does and doesn’t prevent
For example, if your MFA solution is susceptible to man-in-the-middle attacks like shown earlier, make sure everyone using it that you manage is aware that they still have to pay attention to URL links sent to them to make sure they are legitimate. This may sound like common sense, but you'd be surprised how many end-users think that their MFA solution explicitly protects them against rogue phishing links, and that belief can be dangerous.

[KREBS ON SECURITY] How 1-Time Passcodes Became a Corporate Liability
Phishers are enjoying remarkable success using text messages to steal remote access credentials and one-time passcodes from employees at some of the world’s largest technology companies and customer support firms.
A recent spate of SMS phishing attacks from one cybercriminal group has spawned a flurry of breach disclosures from affected companies, which are all struggling to combat the same lingering security threat: The ability of scammers to interact directly with employees through their mobile devices.
In mid-June 2022, a flood of SMS phishing messages began targeting employees at commercial staffing firms that provide customer support and outsourcing to thousands of companies. The missives asked users to click a link and log in at a phishing page that mimicked their employer's Okta authentication page.
Those who submitted credentials were then prompted to provide the one-time password needed for multi-factor authentication.
The phishers behind this scheme used newly registered domains that often included the name of the target company and sent text messages urging employees to click on links to these domains to view information about a pending change in their work schedule.
The phishing sites leveraged a Telegram instant message bot to forward any submitted credentials in real-time, allowing the attackers to use the phished username, password and one-time code to log in as that employee at the real employer website. But because of the way the bot was configured, it was possible for security researchers to capture the information being sent by victims to the public Telegram server.
This data trove was first reported by security researchers at Singapore-based Group-IB, which dubbed the campaign "0ktapus" for the attackers targeting organizations using identity management tools from Okta.com.
"This case is of interest because despite using low-skill methods it was able to compromise a large number of well-known organizations," Group-IB wrote. "Furthermore, once the attackers compromised an organization, they were quickly able to pivot and launch subsequent supply chain attacks, indicating that the attack was planned carefully in advance."
It's not clear how many of these phishing text messages were sent out, but the Telegram bot data reviewed by KrebsOnSecurity shows they generated nearly 10,000 replies over approximately two months of sporadic SMS phishing attacks targeting more than a hundred companies.
A great many responses came from those who were apparently wise to the scheme, as evidenced by the hundreds of hostile replies that included profanity or insults aimed at the phishers: The very first reply recorded in the Telegram bot data came from one such employee, who responded with the username "havefuninjail."
Still, thousands replied with what appear to be legitimate credentials — many of them including one-time codes needed for multi-factor authentication. On July 20, the attackers turned their sights on internet infrastructure giant Cloudflare.com, and the intercepted credentials show at least five employees fell for the scam (although only two employees also provided the crucial one-time MFA code).

Phishing Attacks Leveraging Legitimate SaaS Platforms Soar 1100%
As threat actors look for ways to evade detection by security solutions, the use of cloud applications has seen a material jump in the last 12 months, according to new data.
While we see plenty of cyberattacks that utilize dark infrastructure to accomplish their malicious activities, more and more we're seeing a trend where threat actors are taking advantage of web-based application platforms to utilize their legitimacy to ensure phishing email delivery all the way to the Inbox.
In the latest report from Palo Alto Network's Unit42, "Legitimate SaaS Platforms Being Used to Host Phishing Attacks", we find that the increases are far greater than expected. According to the report, the following types of SaaS platforms were included in their analysis of phishing URLS:

Instagram Phishing: Scammers Exploit Instagram Verification Program
Researchers at Vade warn that an email phishing campaign is informing users that their Instagram account is eligible to receive a blue verification badge. If a user clicks the link, they'll be taken to a spoofed Instagram login page designed to steal their credentials.
"First discovered by Vade in late July, the scam exploits Instagram's highly sought-after verification program to dupe victims into divulging personal information and account credentials," the researchers write. "The malicious attack targets specific users of the social media platform, showing more sophistication than other phishing campaigns that pursue victims indiscriminately."
The emails impersonate Instagram, and are tailored to each target. The phishing page URL is "teamcorrectionbadges[DOT]com."
"The phishing email uses the subject line, 'ig bluebadge info' and the name, 'ig-badges,'" the researchers write. "The body text explains that the victim's Instagram profile has been reviewed and deemed eligible for verification.
"The Instagram and Facebook logos at the header and footer of the email attempt to create an air of legitimacy, as does the use of the victim’s actual Instagram handle, showing the hackers researched their target before the attack." The researchers note that observant users could recognize some discrepancies and signs of social engineering in the email.
84% of Americans Have Experienced Some Form of Social Engineering
Researchers at NordVPN have published the results of a survey that found that 84% of Americans have experienced some form of social engineering, although only 54% have heard of the term "social engineering." 85% percent of the respondents said they were aware of the term "phishing," and 36% said they had fallen victim to a phishing email.
The researchers found that phishing emails are the most common form of social engineering attacks, followed by text message phishing (smishing) and voice phishing (vishing):
- 48% – Suspicious emails with links and attachments and/or asking for their personal information
- 39% – Suspicious texts with links and attachments and/or asking for their personal information
- 37% – Pop-up advertisements that were difficult to close
- 37% – Suspicious email(s) containing links, attachments or asking them to reply and divulge work/business information
- 32% – Suspicious email(s) from someone posing as an important personal who was asking them to wire them funds
- 27% – Suspicious voicemail(s) asking the recipient to divulge personal information
- 26% – A virus on their computer or phone
- 19% – Malware on their device that redirected them to a fake version of a website
ordVPN offers the following advice to help users recognize these types of attacks.
"The point of a social engineered attack is to get you to follow a link or sign up to something," the researchers write. "The best way to recognize a socially engineered attack is to analyze the language of the message.
"Is the language desperate? Does the message imply there's a time limit to whatever request it's asking for? Does the message sound urgent? Remember that most banks will never text you and ask for your login credentials. In fact, any text message or email you receive that requests any kind of login details is probably best suited for the trash bin."
