A shocking number of organizations — including banks and healthcare providers — are leaking private and sensitive information from their public Salesforce Community websites, KrebsOnSecurity has learned. The data exposures all stem from a misconfiguration in Salesforce Community that allows an unauthenticated user to access records that should only be available after logging in.
A researcher found DC Health had five Salesforce Community sites exposing data.
Salesforce Community is a widely-used cloud-based software product that makes it easy for organizations to quickly create websites. Customers can access a Salesforce Community website in two ways: Authenticated access (requiring login), and guest user access (no login required). The guest access feature allows unauthenticated users to view specific content and resources without needing to log in.
However, sometimes Salesforce administrators mistakenly grant guest users access to internal resources, which can cause unauthorized users to access an organization’s private information and lead to potential data leaks.
Until being contacted by this reporter on Monday, the state of Vermont had at least five separate Salesforce Community sites that allowed guest access to sensitive data, including a Pandemic Unemployment Assistance program that exposed the applicant’s full name, Social Security number, address, phone number, email, and bank account number.
This misconfigured Salesforce Community site from the state of Vermont was leaking pandemic assistance loan application data, including names, SSNs, email address and bank account information.
Vermont’s Chief Information Security Officer Scott Carbee said his security teams have been conducting a full review of their Salesforce Community sites, and already found one additional Salesforce site operated by the state that was also misconfigured to allow guest access to sensitive information.
“My team is frustrated by the permissive nature of the platform,” Carbee said.
Carbee said the vulnerable sites were all created rapidly in response to the Coronavirus pandemic, and were not subjected to their normal security review process.
“During the pandemic, we were largely standing up tons of applications, and let’s just say a lot of them didn’t have the full benefit of our dev/ops process,” Carbee said. “In our case, we didn’t have any native Salesforce developers when we had to suddenly stand up all these sites.”
Earlier this week, KrebsOnSecurity notified Columbus, Ohio-based Huntington Bank that its recently acquired TCF Bank had a Salesforce Community website that was leaking documents related to commercial loans. The data fields in those loan applications included name, address, full Social Security number, title, federal ID, IP address, average monthly payroll, and loan amount.
Huntington Bank has disabled the leaky TCF Bank Salesforce website. Matthew Jennings, deputy chief information security officer at Huntington, said the company was still investigating how the misconfiguration occurred, how long it lasted, and how many records may have been exposed.
KrebsOnSecurity learned of the leaks from security researcher Charan Akiri, who said he wrote a program that identified hundreds of other organizations running misconfigured Salesforce pages. But Akiri said he’s been wary of probing too far, and has had difficulty getting responses from most of the organizations he has notified to date.
“In January and February 2023, I contacted government organizations and several companies, but I did not receive any response from these organizations,” Akiri said. “To address the issue further, I reached out to several CISOs on LinkedIn and Twitter. As a result, five companies eventually fixed the problem. Unfortunately, I did not receive any responses from government organizations.”
The problem Akiri has been trying to raise awareness about came to the fore in August 2021, when security researcher Aaron Costello published a blog post explaining how misconfigurations in Salesforce Community sites could be exploited to reveal sensitive data (Costello subsequently published a follow-up post detailing how to lock down Salesforce Community sites).
On Monday, KrebsOnSecurity used Akiri’s findings to notify Washington D.C. city administrators that at least five different public DC Health websites were leaking sensitive information. One DC Health Salesforce Community website designed for health professionals seeking to renew licenses with the city leaked documents that included the applicant’s full name, address, Social Security number, date of birth, license number and expiration, and more.
Akiri said he notified the Washington D.C. government in February about his findings, but received no response. Reached by KrebsOnSecurity, interim Chief Information Security Officer Mike Rupert initially said the District had hired a third party to investigate, and that the third party confirmed the District’s IT systems were not vulnerable to data loss from the reported Salesforce configuration issue.
But after being presented with a document including the Social Security number of a health professional in D.C. that was downloaded in real-time from the DC Health public Salesforce website, Rupert acknowledged his team had overlooked some configuration settings.
Washington, D.C. health administrators are still smarting from a data breach earlier this year at the health insurance exchange DC Health Link, which exposed personal information for more than 56,000 users, including many members of Congress.
That data later wound up for sale on a top cybercrime forum. The Associated Press reports that the DC Health Link breach was likewise the result of human error, and said an investigation revealed the cause was a DC Health Link server that was “misconfigured to allow access to the reports on the server without proper authentication.”
Salesforce says the data exposures are not the result of a vulnerability inherent to the Salesforce platform, but they can occur when customers’ access control permissions are misconfigured.
“As previously communicated to all Experience Site and Sites customers, we recommend utilizing the Guest User Access Report Package to assist in reviewing access control permissions for unauthenticated users,” reads a Salesforce advisory from Sept. 2022. “Additionally, we suggest reviewing the following Help article, Best Practices and Considerations When Configuring the Guest User Profile.”
In a written statement, Salesforce said it is actively focused on data security for organizations with guest users, and that it continues to release “robust tools and guidance for our customers,” including:
Control Which Users Experience Cloud Site Users Can See
Best Practices and Considerations When Configuring the Guest User Profile
“We’ve also continued to update our Guest User security policies, beginning with our Spring ‘21 release with more to come in Summer ‘23,” the statement reads. “Lastly, we continue to proactively communicate with customers to help them understand the capabilities available to them, and how they can best secure their instance of Salesforce to meet their security, contractual, and regulatory obligations.”
For Cisco engineers working on Duo, having a remote-first workplace has helped them reach life goals, connect with colleagues around the world, and be intentional communicators. We understand that working remotely can be an adjustment — that’s why we’ve compiled the 10 parts of remote work that surprised our team members most and their advice for navigating the nuances. If you’re interested in being part of a remote-first workplace, check out our open positions.
Senior Engineering Leader David Rines has worked remotely for the past seven years. He’s found that Cisco’s approach to distributed teams has “enabled us to pick up the right talent, and not necessarily local talent. We are moving towards a global, follow the sun environment,” he said.
One of the aspects Rines appreciates most of this structure is getting “a widely varied set of perspectives and experiences that help build a more reliable, more robust product, which is why we’re here.”
Another benefit to having colleagues across the globe is the sharing of recipes, a perk Senior Site Reliability Engineer Bernard Ting particularly enjoys. Proactively communicating with colleagues virtually “helps you to form bonds with people from other teams. You can always learn something new about cultures elsewhere. I talk to people about food and so I’m always gathering recipes from people from all over the world,” Ting shared.
While some may fear that working remotely could lead to feelings of isolation and loneliness, a different camaraderie can flourish in the structure of our distributed teams. With colleagues across time zones, “there’s always someone there who you can reach out to help solve your problem,” Rines said.
Collaboration hours are another way Site Reliability Engineering Manager Jaya Sistla has cultivated virtual community and problem-solving. These hours are blocked off for team members to talk about what they’re working on. “The main thing is being able to ask for help so you don’t go into the rabbit hole debugging things,” Sistla said.
Ting points out that working in a distributed model allows you to really engage in virtual events and conversations. Given that the team mainly communicates through online chat, Ting has found that “forces you to see everyone as equally approachable, which has made me more comfortable reaching out to people from anywhere in the world.”
For folks sharing an office, collaboration can happen through casual chats over coffee. When facing a challenge, you can ask your neighbor for support. While ideally virtual communication could have a similar cadence and spontaneity, the logistics of remote and distributed work require intentionality and being proactive in connecting with colleagues as people and as co-workers.
When Ting first started working remotely, he felt that every meeting needed to be formal and have a business objective. By sharing his feelings with his manager, he was reassured that “socializing is a very important part of teamwork, because if you don’t have a good relationship with your colleagues you’re not going to be able to have healthy discussions, healthy conflict or be able to critique each other when the situation arises.”
Since that conversation, Ting has been more proactive about catching up with colleagues, which can include sharing a coffee over video chat. Duo’s “coffee roulette” formalizes the process as every month, employees who opt in can be randomly paired up for a quick half-hour chat focused exclusively on socializing. Ting has found being proactive about socializing virtually helpful. “It’s made me more intentional with my time and really treasure the social experience you can get,” he said.
Some folks may be concerned that without a manager observing their efforts and work ethic day in and day out, it may be harder to recognize accomplishments and challenges. Ting found that within his team “when you work on projects and in your one-on-ones with your managers, they’re always very intentional about learning what you’ve been doing and seeing what your progress is like on certain projects. I’ve been asked, ‘How do you think you can improve? What are some of the things you’ve been doing outside of the team work?’”
To cultivate cross-team collaboration and education, there are thoughtfully planned virtual lunch and learns. “We schedule training sessions and common meetings at times that are flexible for everyone. If it has to be repeated, we do it so people can comfortably attend rather than stretching themselves and attending at odd hours,” Sistla said.
For Software Engineer Nick Aspinall, an important and fun part of working remotely is keeping in touch with virtual messaging. One unique perk has been getting to create and customize emojis with team members including a few of himself in “various ridiculous states,” he said.
Connecting with colleagues on themed channels focused on personal and professional interests from coffee to pets “makes it really cool because you can meet people across different teams and still get some of the feeling of rubbing elbows that you get when you’re in the office,” Aspinall said. Participating in these virtual conversations boosts morale while also providing an endless supply of cute animal pics.
Given the multi-faceted nature of our work and the importance of consistent information sharing, having different communication channels and formats to communicate data with varying degrees of complexity is vital. Having information readily accessible, accurate and updated is particularly necessary in a field like cybersecurity.
Senior Software Engineer Mario Lopez finds that the variety of information sources contributes to an easeful remote working experience. For instance, for complex architecture decisions or detailing, Duo’s Wiki is the best source.
Software Engineer Hanna Fernandez has benefited from chat channels dedicated to design and engineering topics to “see what everyone’s up to and what thoughts people have,” she said. Sista pointed out these are great places to ask questions and open up dialogue to solve problems.
Our culture is “video-on,” meaning that it is preferred that during video meetings, as much as possible, attendees have their cameras on. Lopez loves this because “you get a bit of that personal human element.”
“We’re all people behind these screens. You definitely get some of people’s personality through text, but you get it more when you actually see them. It’s infectious when you see someone smiling. You’ve got to smile back,” he shared (while we both smiled).
When Fernandez started at Cisco, she was advised to schedule individual meetings with everyone she would be working with on every team that she joined. That suggestion is one she’s applied even virtually.
“It’s a great strategy because I already know that my team is super talented and very smart, but this way I also get to know them as humans beyond their roles,” Fernandez said. Fernandez also finds it important to check in with co-workers and ask how they’re feeling and how their time off was. “I know a lot of people hate small talk, but it’s not just small talk. I’m genuinely interested in how my co-workers are doing.”
One of Ting’s biggest goals was buying his first house in the countryside outside of London. By working remotely, Ting has flexibility in his location which allowed him to achieve his goal of buying a house and settling down with his partner, while giving their dogs the space they need to be dogs.
When transitioning from fully remote to hybrid, it’s important to recognize that there will be some shifts to get accustomed to. As the structures of remote, distributed and hybrid work evolve, it’s important to stay flexible and notice what’s possible through multiple modalities of team building. Many teams have enjoyed in-person gatherings and connecting through virtual lunches and team games when remote.
Fernandez has had multiple roles with multiple structures at Cisco. As an intern, she was fully in person and shared desk space with other interns who collaborated on full stack engineering. While working in finance IT, Fernandez was hybrid and many of her colleagues were distributed among multiple offices. The pandemic began while she was in a DevOps role, forcing her to maintain boundaries around her work time while working fully remotely. In her current role working on Duo, Fernandez is completely remote but advocates for in-person events if possible, because “humans are social creatures who want to see each other’s faces in real life once in a while.”
For Aspinall, “when we did come back to the office, there was a bit of an adjustment period where you were overstimulated from the office.” He also wanted to ensure team members who were 100% remote were fully included. Now he sees that while half his team is fully remote and the other half is hybrid, “that doesn’t stop anyone from doing anything. All of our meetings feel the same. They’re all seamless.”

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 three employees fell for the scam.

In a blog post earlier this month, Cloudflare said it detected the account takeovers and that no Cloudflare systems were compromised. Cloudflare said it does not rely on one-time passcodes as a second factor, so there was nothing to provide to the attackers. But Cloudflare said it wanted to call attention to the phishing attacks because they would probably work against most other companies.
“This was a sophisticated attack targeting employees and systems in such a way that we believe most organizations would be likely to be breached,” Cloudflare CEO Matthew Prince wrote. “On July 20, 2022, the Cloudflare Security team received reports of employees receiving legitimate-looking text messages pointing to what appeared to be a Cloudflare Okta login page. The messages began at 2022-07-20 22:50 UTC. Over the course of less than 1 minute, at least 76 employees received text messages on their personal and work phones. Some messages were also sent to the employees family members.”
On three separate occasions, the phishers targeted employees at Twilio.com, a San Francisco based company that provides services for making and receiving text messages and phone calls. It’s unclear how many Twilio employees received the SMS phishes, but the data suggest at least four Twilio employees responded to a spate of SMS phishing attempts on July 27, Aug. 2, and Aug. 7.
On that last date, Twilio disclosed that on Aug. 4 it became aware of unauthorized access to information related to a limited number of Twilio customer accounts through a sophisticated social engineering attack designed to steal employee credentials.
“This broad based attack against our employee base succeeded in fooling some employees into providing their credentials,” Twilio said. “The attackers then used the stolen credentials to gain access to some of our internal systems, where they were able to access certain customer data.”
That “certain customer data” included information on roughly 1,900 users of the secure messaging app Signal, which relied on Twilio to provide phone number verification services. In its disclosure on the incident, Signal said that with their access to Twilio’s internal tools the attackers were able to re-register those users’ phone numbers to another device.
On Aug. 25, food delivery service DoorDash disclosed that a “sophisticated phishing attack” on a third-party vendor allowed attackers to gain access to some of DoorDash’s internal company tools. DoorDash said intruders stole information on a “small percentage” of users that have since been notified. TechCrunch reported last week that the incident was linked to the same phishing campaign that targeted Twilio.
This phishing gang apparently had great success targeting employees of all the major mobile wireless providers, but most especially T-Mobile. Between July 10 and July 16, dozens of T-Mobile employees fell for the phishing messages and provided their remote access credentials.
“Credential theft continues to be an ongoing issue in our industry as wireless providers are constantly battling bad actors that are focused on finding new ways to pursue illegal activities like this,” T-Mobile said in a statement. “Our tools and teams worked as designed to quickly identify and respond to this large-scale smishing attack earlier this year that targeted many companies. We continue to work to prevent these types of attacks and will continue to evolve and improve our approach.”
This same group saw hundreds of responses from employees at some of the largest customer support and staffing firms, including Teleperformanceusa.com, Sitel.com and Sykes.com. Teleperformance did not respond to requests for comment. KrebsOnSecurity did hear from Christopher Knauer, global chief security officer at Sitel Group, the customer support giant that recently acquired Sykes. Knauer said the attacks leveraged newly-registered domains and asked employees to approve upcoming changes to their work schedules.

Knauer said the attackers set up the phishing domains just minutes in advance of spamming links to those domains in phony SMS alerts to targeted employees. He said such tactics largely sidestep automated alerts generated by companies that monitor brand names for signs of new phishing domains being registered.
“They were using the domains as soon as they became available,” Knauer said. “The alerting services don’t often let you know until 24 hours after a domain has been registered.”
On July 28 and again on Aug. 7, several employees at email delivery firm Mailchimp provided their remote access credentials to this phishing group. According to an Aug. 12 blog post, the attackers used their access to Mailchimp employee accounts to steal data from 214 customers involved in cryptocurrency and finance.
On Aug. 15, the hosting company DigitalOcean published a blog post saying it had severed ties with MailChimp after its Mailchimp account was compromised. DigitalOcean said the MailChimp incident resulted in a “very small number” of DigitalOcean customers experiencing attempted compromises of their accounts through password resets.
According to interviews with multiple companies hit by the group, the attackers are mostly interested in stealing access to cryptocurrency, and to companies that manage communications with people interested in cryptocurrency investing. In an Aug. 3 blog post from email and SMS marketing firm Klaviyo.com, the company’s CEO recounted how the phishers gained access to the company’s internal tools, and used that to download information on 38 crypto-related accounts.

The ubiquity of mobile phones became a lifeline for many companies trying to manage their remote employees throughout the Coronavirus pandemic. But these same mobile devices are fast becoming a liability for organizations that use them for phishable forms of multi-factor authentication, such as one-time codes generated by a mobile app or delivered via SMS.
Because as we can see from the success of this phishing group, this type of data extraction is now being massively automated, and employee authentication compromises can quickly lead to security and privacy risks for the employer’s partners or for anyone in their supply chain.
Unfortunately, a great many companies still rely on SMS for employee multi-factor authentication. According to a report this year from Okta, 47 percent of workforce customers deploy SMS and voice factors for multi-factor authentication. That’s down from 53 percent that did so in 2018, Okta found.
Some companies (like Knauer’s Sitel) have taken to requiring that all remote access to internal networks be managed through work-issued laptops and/or mobile devices, which are loaded with custom profiles that can’t be accessed through other devices.
Others are moving away from SMS and one-time code apps and toward requiring employees to use physical FIDO multi-factor authentication devices such as security keys, which can neutralize phishing attacks because any stolen credentials can’t be used unless the phishers also have physical access to the user’s security key or mobile device.
This came in handy for Twitter, which announced last year that it was moving all of its employees to using security keys, and/or biometric authentication via their mobile device. The phishers’ Telegram bot reported that on June 16, 2022, five employees at Twitter gave away their work credentials. In response to questions from KrebsOnSecurity, Twitter confirmed several employees were relieved of their employee usernames and passwords, but that its security key requirement prevented the phishers from abusing that information.
Twitter accelerated its plans to improve employee authentication following the July 2020 security incident, wherein several employees were phished and relieved of credentials for Twitter’s internal tools. In that intrusion, the attackers used Twitter’s tools to hijack accounts for some of the world’s most recognizable public figures, executives and celebrities — forcing those accounts to tweet out links to bitcoin scams.
“Security keys can differentiate legitimate sites from malicious ones and block phishing attempts that SMS 2FA or one-time password (OTP) verification codes would not,” Twitter said in an Oct. 2021 post about the change. “To deploy security keys internally at Twitter, we migrated from a variety of phishable 2FA methods to using security keys as our only supported 2FA method on internal systems.”
Update, 6:02 p.m. ET: Clarified that Cloudflare does not rely on TOTP (one-time multi-factor authentication codes) as a second factor for employee authentication.
Businesses today have many options for interacting with customers online. The findings of our independent survey of online consumers suggest that websites and branded email continue to be critical components of many businesses’ online presence, essential to supporting consumer confidence and enabling effective interaction with customers.
The quantitative study, commissioned by Verisign and conducted in December 2019 and January 2020 by 451 Research, now a part of S&P Global Market Intelligence, surveyed 5,450 online consumers across key markets in North America, Latin America, Europe and Asia to help understand their sentiments on interacting with businesses online.
The survey was designed to arm service providers and registrars with an understanding of how the resources they provide to businesses can help create trust and deliver value to their customers.
Among those surveyed, approximately two-thirds (66%) agreed that a business with its own website is more credible than one without. Likewise, a majority indicated that they would expect it to be more difficult to verify the identity of (56%), find online (55%) and contact (54%) a business that does not have its own website.
Certainly, this doesn’t suggest that businesses should abandon other online channels, such as social media and search engine efforts, to focus on a website-only approach. Instead, 64% of respondents said that a business with many points of online presence is more credible than a business with few.
Still, the study suggests that other online resources should complement, rather than replace, a small business’s own website. Respondents identified a business’s own website as being one of the most popular online methods for learning about (69%) and conducting transactions with (57%) businesses. Further, 71% of respondents reported being more likely to recommend a business with a professional website.
Taken together, these findings suggest that a website can help add credibility and drive new business.
Trust is central to the relationship between a business and customers. This may be particularly true for online transactions (95% of survey respondents said they actively make purchases online), which require consumers to trust not only that the business will deliver the product or service for which they have paid, but also that it will not misuse payment or personal information.
A branded email address may be able to help, as an overwhelming number of respondents (85%) agreed that a business with a branded email address is more credible than one that uses a free email account. Respondents were more likely to have used a business’s branded email address (67%), than the telephone (56%) or social media (40%), to communicate with a business during the prior 12 months.
For a small business, failing to be perceived as credible online could mean lost business not just today, but also in the future. A website and branded email address can help businesses add credibility and more effectively engage with consumers online.
Service providers offer a variety of website-building tools, email hosting solutions, and domain name registration services that can help businesses – whether just starting or well-established – to have a website and use a branded email.
Detailed survey results are available in 451 Research’s Black & White Paper Websites, Branded Email Remain Key to SMB Internet Services.
