Earlier this month, employees at more than 1,000 companies saw one or two paycheck’s worth of funds deducted from their bank accounts after the CEO of their cloud payroll provider absconded with $35 million in payroll and tax deposits from customers. On Monday, the CEO was arrested and allegedly confessed that the diversion was the last desperate gasp of a financial shell game that earned him $70 million over several years.

Michael T. Mann, the 49-year-old CEO of Clifton Park, NY-based MyPayrollHR, was arrested this week and charged with bank fraud. In court filings, FBI investigators said Mann admitted under questioning that in early September — on the eve of a big payroll day — he diverted to his own bank account some $35 million in funds sent by his clients to cover their employee payroll deposits and tax withholdings.

After that stunt, two different banks that work with Mann’s various companies froze those corporate accounts to keep the funds from being moved or withdrawn. That action set off a chain of events that led another financial institution that helps MyPayrollHR process payments to briefly pull almost $26 million out of checking accounts belonging to employees at more than 1,000 companies that use MyPayrollHR.

At the same time, MyPayrollHR sent a message (see screenshot above) to clients saying it was shutting down and that customers should find alternative methods for paying employees and for processing payroll going forward.

In the criminal complaint against Mann (PDF), a New York FBI agent said the CEO admitted that starting in 2010 or 2011 he began borrowing large sums of money from banks and financing companies under false pretenses.

“While stating that MyPayroll was legitimate, he admitted to creating other companies that had no purpose other than to be used in the fraud; fraudulently representing to banks and financing companies that his fake businesses had certain receivables that they did not have; and obtaining loans and lines of credit by borrowing against these non-existent receivables.”

“Mann estimated that he fraudulently obtained about $70 million that he has not paid back. He claimed that he committed the fraud in response to business and financial pressures, and that he used almost all of the fraudulently obtained funds to sustain certain businesses, and purchase and start new ones. He also admitted to kiting checks between Bank of America and Pioneer [Savings Bank], as part of the fraudulent scheme.”

Check-kiting is the illegal act of writing a check from a bank account without sufficient funds and depositing it into another bank account, explains MagnifyMoney.com. “Then, you withdraw the money from that second account before the original check has been cleared.”

Kiting also is known as taking advantage of the “float,” which is the amount of time between when an individual submits a check as payment and when the individual’s bank is instructed to move the funds from the account.

Magnify Money explains more:

“Say, for example, that you write yourself a check for $500 from checking account A, and deposit that check into checking account B — but the balance in checking account A is only $75. Then, you promptly withdraw the $500 from checking account B. This is check-kiting, a form of check fraud that uses non-existent funds in a checking account or other type of bank account. Some check-kiting schemes use multiple accounts at a single bank, and more complicated schemes involve multiple financial institutions.”

“In a more complex scenario, a person could open checking accounts at bank A and bank B, at first depositing $500 into bank A and nothing in bank B. Then, they could write a check for $10,000 with account A and deposit it into account B. Bank B immediately credits the account, and in the time it might take for bank B to clear the check (generally about three business days), the scammer writes a $10,000 check with bank B, which gets deposited into bank A to cover the first check. This could keep going, with someone writing checks between banks where there’s no actual funds, yet the bank believes the money is real and continues to credit the accounts.”

The government alleges Mann was kiting millions of dollars in checks between his accounts at Bank of American and Pioneer from Aug. 1, 2019 to Aug. 30, 2019.

For more than a decade, MyPayrollHR worked with California-based Cachet Financial Services to process payroll deposits for MyPayrollHR client employees. Every other week, MyPayrollHR’s customers would deposit their payroll funds into a holding account run by Cachet, which would then disburse the payments into MyPayrollHR client employee bank accounts.

But when Mann diverted $26 million in client payroll deposits from Cachet to his account at Pioneer Bank, Cachet’s emptied holding account was debited for the payroll payments. Cachet quickly reversed those deposits, causing one or two pay periods worth of salary to be deducted from bank accounts for employees of companies that used MyPayrollHR.

That action caused so much uproar from affected companies and their employees that Cachet ultimately decided to cancel all of those reversals and absorb that $26 million hit, which it is now trying to recover through the courts.

According to prosecutors in New York, Pioneer was Mann’s largest creditor.

“Mann stated that the payroll issue was precipitated by his decision to route MyPayroll’s clients’ payroll payments to an account at Pioneer instead of directly to Cachet,” wrote FBI Special Agent Matthew J. Wabby. “He did this in order to temporarily reduce the amount of money he owed to Pioneer. When Pioneer froze Mann’s accounts, it’s also (inadvertently) stopped movement of MyPayroll’s clients’ payroll payments to Cachet.”

Approximately $9 million of the $35 million diverted by Mann was supposed to go to accounts at the National Payment Corporation (NatPay) — the Florida-based firm which handles tax withholdings for MyPayrollHR clients. NatPay said its insurance should help cover the losses it incurred when MyPayrollHR’s banks froze the company’s accounts.

Court records indicate Mann hasn’t yet entered a plea, but that he was ordered to be released today under a $200,000 bond secured by a family home and two vehicles. His passport also was seized.

In April 2013, I received via U.S. mail more than a gram of pure heroin as part of a scheme to get me arrested for drug possession. But the plan failed and the Ukrainian mastermind behind it soon after was imprisoned for unrelated cybercrime offenses. That individual recently gave his first interview since finishing his jail time here in the states, and he’s shared some select (if often abrasive and coarse) details on how he got into cybercrime and why. Below are a few translated excerpts.

When I first encountered now-31-year-old Sergei “Fly,” “Flycracker,” “MUXACC” Vovnenko in 2013, he was the administrator of the fraud forum “thecc[dot]bz,” an exclusive and closely guarded Russian language board dedicated to financial fraud and identity theft.

Many of the heavy-hitters from other fraud forums had a presence on Fly’s forum, and collectively the group financed and ran a soup-to-nuts network for turning hacked credit card data into mounds of cash.

Vovnenko first came onto my radar after his alter ego Fly published a blog entry that led with an image of my bloodied, severed head and included my credit report, copies of identification documents, pictures of our front door, information about family members, and so on. Fly had invited all of his cybercriminal friends to ruin my financial identity and that of my family.

Somewhat curious about what might have precipitated this outburst, I was secretly given access to Fly’s cybercrime forum and learned he’d freshly hatched a plot to have heroin sent to my home. The plan was to have one of his forum lackeys spoof a call from one of my neighbors to the police when the drugs arrived, complaining that drugs were being delivered to our house and being sold out of our home by Yours Truly.

Thankfully, someone on Fly’s forum also posted a link to the tracking number for the drug shipment. Before the smack arrived, I had a police officer come out and take a report. After the heroin showed up, I gave the drugs to the local police and wrote about the experience in Mail From the Velvet Cybercrime Underground.

Angry that I’d foiled the plan to have me arrested for being a smack dealer, Fly or someone on his forum had a local florist send a gaudy floral arrangement in the shape of a giant cross to my home, complete with a menacing message that addressed my wife and was signed, “Velvet Crabs.”

Vovnenko was arrested in Italy in the summer of 2014 on identity theft and botnet charges, and spent some 15 months in arguably Italy’s worst prison contesting his extradition to the United States. Those efforts failed, and he soon pleaded guilty to aggravated identity theft and wire fraud, and spent several years bouncing around America’s prison system.

Although Vovnenko sent me a total of three letters from prison in Naples (a hand-written apology letter and two friendly postcards), he never responded to my requests to meet him following his trial and conviction on cybercrime charges in the United States. I suppose that is fair: To my everlasting dismay, I never responded to his Italian dispatches (the first I asked to be professionally analyzed and translated before I would touch it).

After serving his 41 month sentence in the U.S., Vovnenko was deported, although it’s unclear where he currently resides (the interview excerpted here suggests he’s back in Italy, but Fly doesn’t exactly confirm that). 

In an interview published on the Russian-language security blog Krober[.]biz, Vovnenko said he began stealing early in life, and by 13 was already getting picked up for petty robberies and thefts.

A translated English version of the interview was produced and shared with KrebsOnSecurity by analysts at New York City-based cyber intelligence firm Flashpoint.

Sometime in the mid-aughts, Vovnenko settled with his mother in Naples, Italy, but he had trouble keeping a job for more than a few days. Until a chance encounter led to a front job at a den of thieves.

“When I came to my Mom in Naples, I could not find a permanent job. Having settled down somewhere at a new job, I would either get kicked out or leave in the first two days. I somehow didn’t succeed with employment until I was invited to work in a wine shop in the historical center of Naples, where I kinda had to wipe the dust from the bottles. But in fact, the wine shop turned out to be a real den and a sales outlet of hashish and crack. So my job was to be on the lookout and whenever the cops showed up, take a bag of goods and leave under the guise of a tourist.”

Cocaine and hash were plentiful at his employer’s place of work, and Vovnenko said he availed himself of both abundantly. After he’d saved enough to buy a computer, Fly started teaching himself how to write programs and hack stuff. He quickly became enthralled with the romanticized side of cybercrime — the allure of instant cash — and decided this was his true vocation.

“After watching movies and reading books about hackers, I really wanted to become a sort of virtual bandit who robs banks without leaving home,” Vovnenko recalled. “Once, out of curiosity, I wrote an SMS bomber that used a registration form on a dating site, bypassing the captcha through some kind of rookie mistake in the shitty code. The bomber would launch from the terminal and was written in Perl, and upon completion of its work, it gave out my phone number and email. I shared the bomber somewhere on one of my many awkward sites.”

“And a couple of weeks later they called me. Nah, not the cops, but some guy who comes from Sri Lanka who called himself Enrico. He told me that he used my program and earned a lot of money, and now he wants to share some of it with me and hire me. By a happy coincidence, the guy also lived in Naples.”

“When we met in person, he told me that he used my bomber to fuck with a telephone company called Wind. This telephone company had such a bonus service: for each incoming SMS you received two cents on the balance. Well, of course, this guy bought a bunch of SIM cards and began to bomb them, getting credits and loading them into his paid lines, similar to how phone sex works.”

But his job soon interfered with his drug habit, and he was let go.

“At the meeting, Enrico gave me 2K euros, and this was the first money I’ve earned, as it is fashionable to say these days, on ‘cybercrime’. I left my previous job and began to work closely with Enrico. But always stoned out of my mind, I didn’t do a good job and struggled with drug addiction at that time. I was addicted to cocaine, as a result, I was pulling a lot more money out of Enrico than my work brought him. And he kicked me out.”

After striking out on his own, Vovnenko says he began getting into carding big time, and was introduced to several other big players on the scene. One of those was a cigarette smuggler who used the nickname Ponchik (“Doughnut”).

I wonder if this is the same Ponchik who was arrested in 2013 as being the mastermind behind the Blackhole exploit kit, a crimeware package that fueled an overnight explosion in malware attacks via Web browser vulnerabilities.

In any case, Vovnenko had settled on some schemes that were generating reliably large amounts of cash.

“I’ve never stood still and was not focusing on carding only, with the money I earned, I started buying dumps and testing them at friends’ stores,” Vovnenko said. “Mules, to whom I signed the hotlines, were also signed up for cashing out the loads, giving them a mere 10 percent for their work. Things seemed to be going well.”

FAN MAIL

There is a large chronological gap in Vovnenko’s account of his cybercrime life story from that point on until the time he and his forum friends started sending heroin, large bags of feces and other nasty stuff to our Northern Virginia home in 2013.

Vovnenko claims he never sent anything and that it was all done by members of his forum.

-Tell me about the packages to Krebs.
“That ain’t me. Suitcase filled with sketchy money, dildoes, and a bouquet of coffin wildflowers. They sent all sorts of crazy shit. Forty or so guys would send. When I was already doing time, one of the dudes sent it. By the way, Krebs wanted to see me. But the lawyer suggested this was a bad idea. Maybe he wanted to look into my eyes.”

In one part of the interview, Fly is asked about but only briefly touches on how he was caught. I wanted to add some context here because this part of the story is richly ironic, and perhaps a tad cathartic.

Around the same time Fly was taking bitcoin donations for a fund to purchase heroin on my behalf, he was also engaged to be married to a nice young woman. But Fly apparently did not fully trust his bride-to-be, so he had malware installed on her system that forwarded him copies of all email that she sent and received.

But Fly would make at least two big operational security mistakes in this spying effort: First, he had his fiancée’s messages forwarded to an email account he’d used for plenty of cybercriminal stuff related to his various “Fly” identities.

Mistake number two was the password for his email account was the same as one of his cybercrime forum admin accounts. And unbeknownst to him at the time, that forum was hacked, with all email addresses and hashed passwords exposed.

Soon enough, investigators were reading Fly’s email, including the messages forwarded from his wife’s account that had details about their upcoming nuptials, such as shipping addresses for their wedding-related items and the full name of Fly’s fiancée. It didn’t take long to zero in on Fly’s location in Naples.

While it may sound unlikely that a guy so immeshed in the cybercrime space could make such rookie security mistakes, I have found that a great many cybercriminals actually have worse operational security than the average Internet user.

I suspect this may be because the nature of their activities requires them to create vast numbers of single- or brief-use accounts, and in general they tend to re-use credentials across multiple sites, or else pick very poor passwords — even for critical resources.

In addition to elaborating on his hacking career, Fly talks a great deal about his time in various prisons (including their culinary habits), and an apparent longing or at least lingering fondness for the whole carding scene in general.

Towards the end, Fly says he’s considering going back to school, and that he may even take up information security as a study. I wish him luck in that whatever that endeavor is as long as he can also avoid stealing from people.

I don’t know what I would have written many years ago to Fly had I not been already so traumatized by receiving postal mail from him. Perhaps it would go something like this:

“Dear Fly: Thank you for your letters. I am very sorry to hear about the delays in your travel plans. I wish you luck in all your endeavors — and I sincerely wish the next hopeful opportunity you alight upon does not turn out to be a pile of shit.”

The entire translated interview is here (PDF). Fair warning: Many readers may find some of the language and topics discussed in the interview disturbing or offensive.

A reader forwarded what he briefly imagined might be a bold, if potentially costly, innovation on the old Nigerian prince scam that asks for help squirreling away millions in unclaimed fortune: It was sent via the U.S. Postal Service, with a postmarked stamp and everything.

In truth these old fashioned “advance fee” or “419” scams predate email and have circulated via postal mail in various forms and countries over the years.

The recent one pictured below asks for help in laundering some $11.6 million from an important dead person that anyway has access to a secret stash of cash. Any suckers who bite are strung along for weeks while imaginary extortionists or crooked employees at these bureaucratic institutions demand licenses, bribes or other payments before disbursing any funds. Those funds never arrive, no matter how much money the sucker gives up.

It’s easy to laugh at this letter, because it’s sometimes funny when scammers try so hard. But then again, maybe the joke’s on us because sending these scams via USPS makes them even more appealing to the people most vulnerable: Older individuals with access to cash but maybe not all their marbles. 

Sure, the lure costs $.55 up front. But a handful of successful responses to thousands of mailers could net fortunes for these guys phishing it old school.

The losses from these types of scams are sometimes hard to track because so many go unreported. But they are often perpetrated by the same people involved in romance scams online and in so-called ‘business email compromise” or BEC fraud, wherein the scammers try to spoof the boss at a major company in a bid to get wire payment for an “urgent” (read: fraudulent) invoice.

These scam letters are sometimes called 419 scams in reference to the penal code for dealing with such crimes in Nigeria, a perennial source of 419 letter schemes. A recent bust of a Nigerian gang targeted by the FBI gives some perspective on the money-making abilities of a $10 million ring that was running these scams all day long.

Reportedly, in the first seven months of 2019 alone the FBI received nearly 14,000 complaints reporting BEC scams with a total loss of around $1.1 billion—a figure that nearly matches losses reported for all of 2018.

An Ohio teen who recruited a convicted serial “swatter “to fake a distress call that ended in the police shooting an innocent Kansas man in 2017 has been sentenced to 15 months in prison.

“Swatting” is a dangerous hoax that involves making false claims to emergency responders about phony hostage situations or bomb threats, with the intention of prompting a heavily-armed police response to the location of the claimed incident.

The tragic swatting hoax that unfolded on the night of Dec. 28, 2017 began with a dispute over a $1.50 wager in an online game “Call of Duty” between Shane M. Gaskill, a 19-year-old Wichita, Kansas resident, and Casey S. Viner, 18, from the Cincinnati, OH area.

Viner wanted to get back at Gaskill in grudge over the Call of Duty match, and so enlisted the help of another man — Tyler R. Barriss — a serial swatter in California known by the alias “SWAuTistic” who’d bragged of swatting hundreds of schools and dozens of private residences.

Chat transcripts presented by prosecutors showed Viner and Barriss both saying if Gaskill isn’t scared of getting swatted, he should give up his home address. But the address that Gaskill gave Viner to pass on to Barriss no longer belonged to him and was occupied by a new tenant.

Barriss’s fatal call to 911 emergency operators in Wichita was relayed from a local, non-emergency line. Barriss falsely claimed he was at the address provided by Viner, that he’d just shot his father in the head, was holding his mom and sister at gunpoint, and was thinking about burning down the home with everyone inside.

Wichita police quickly responded to the fake hostage report and surrounded the address given by Gaskill. Seconds later, 28-year-old Andrew Finch exited his mom’s home and was killed by a single shot from a Wichita police officer. Finch, a father of two, had no party to the gamers’ dispute and was simply in the wrong place at the wrong time.

“Swatting is not a prank, and it is no way to resolve disputes among gamers,” U.S. Attorney Stephen McAllister, said in a press statement. “Once again, I call upon gamers to self-police their community to ensure that the practice of swatting is ended once and for all.”

In chat records presented by prosecutors, Viner admitted to his role in the deadly swatting attack:

Defendant VINER: I literally said you’re gonna be swatted, and the guy who swatted him can easily say I convinced him or something when I said hey can you swat this guy and then gave him the address and he said yes and then said he’d do it for free because I said he doesn’t think anything will happen
Defendant VINER: How can I not worry when I googled what happens when you’re involved and it said a eu [sic] kid and a US person got 20 years in prison min
Defendant VINER: And he didn’t even give his address he gave a false address apparently
J.D.: You didn’t call the hoax in…
Defendant VINER: Does t [sic] even matter ?????? I was involved I asked him to do it in the first place
Defendant VINER: I gave him the address to do it, but then again so did the other guy he gave him the address to do it as well and said do it pull up etc

Barriss was sentenced earlier this year to 20 years in federal prison for his role in the fatal swatting attack.

Barriss also pleaded guilty to making hoax bomb threats in phone calls to the headquarters of the FBI and the Federal Communications Commission in Washington, D.C. In addition, he made bomb threat and swatting calls from Los Angeles to emergency numbers in Ohio, New Hampshire, Nevada, Massachusetts, Illinois, Utah, Virginia, Texas, Arizona, Missouri, Maine, Pennsylvania, New Mexico, New York, Michigan, Florida and Canada.

Prosecutors for the county that encompasses Wichita decided in April 2018 that the officer who fired the shot that killed Andrew Finch would not face charges, and would not be named because he wasn’t being charged with a crime.

Viner was sentenced after pleading guilty to one count each of conspiracy and obstructing justice, the US attorney’s office for Kansas said. CNN reports that Gaskill has been placed on deferred prosecution.

Viner’s obstruction charge stems from attempts to erase records of his communications with Barriss and the Wichita gamer, McAllister’s office said. In addition to his prison sentence, Viner was ordered to pay $2,500 in restitution and serve two years of supervised release.

MyPayrollHR, a now defunct cloud-based payroll processing firm based in upstate New York, abruptly ceased operations this past week after stiffing employees at thousands of companies. The ongoing debacle, which allegedly involves malfeasance on the part of the payroll company’s CEO, resulted in countless people having money drained from their bank accounts and has left nearly $35 million worth of payroll and tax payments in legal limbo.

Unlike many stories here about cloud service providers being extorted by hackers for ransomware payouts, this snafu appears to have been something of an inside job. Nevertheless, it is a story worth telling, in part because much of the media coverage of this incident so far has been somewhat disjointed, but also because it should serve as a warning to other payroll providers about how quickly and massively things can go wrong when a trusted partner unexpectedly turns rogue.

Clifton Park, NY-based MyPayrollHR — a subsidiary of ValueWise Corp. — disclosed last week in a rather unceremonious message to some 4,000 clients that it would be shutting its virtual doors and that companies which relied upon it to process payroll payments should kindly look elsewhere for such services going forward.

This communique came after employees at companies that depend on MyPayrollHR to receive direct deposits of their bi-weekly payroll payments discovered their bank accounts were instead debited for the amounts they would normally expect to accrue in a given pay period.

To make matters worse, many of those employees found their accounts had been dinged for two payroll periods — a month’s worth of wages — leaving their bank accounts dangerously in the red.

The remainder of this post is a deep-dive into what we know so far about what transpired, and how such an occurrence might be prevented in the future for other payroll processing firms.

A $26 MILLION TEXT FILE

To understand what’s at stake here requires a basic primer on how most of us get paid, which is a surprisingly convoluted process. In a typical scenario, our employer works with at least one third party company to make sure that on every other Friday what we’re owed gets deposited into our bank account.

The company that handled that process for MyPayrollHR is a California firm called Cachet Financial Services. Every other week for more than 12 years, MyPayrollHR has submitted a file to Cachet that told it which employee accounts at which banks should be credited and by how much.

According to interviews with Cachet, the way the process worked ran something like this: MyPayrollHR would send a digital file documenting deposits made by each of these client companies which laid out the amounts owed to each clients’ employees. In turn, those funds from MyPayrollHR client firms then would be deposited into a settlement or holding account maintained by Cachet.

From there, Cachet would take those sums and disburse them into the bank accounts of people whose employers used MyPayrollHR to manage their bi-weekly payroll payments.

But according to Cachet, something odd happened with the instructions file MyPayrollHR submitted on the afternoon of Wednesday, Sept. 4 that had never before transpired: MyPayrollHR requested that all of its clients’ payroll dollars be sent not to Cachet’s holding account but instead to an account at Pioneer Savings Bank that was operated and controlled by MyPayrollHR.

The total amount of this mass payroll deposit was approximately $26 million. Wendy Slavkin, general counsel for Cachet, told KrebsOnSecurity that her client then inquired with Pioneer Savings about the wayward deposit and was told MyPayrollHR’s bank account had been frozen.

Nevertheless, the payroll file submitted by MyPayrollHR instructed financial institutions for its various clients to pull $26 million from Cachet’s holding account — even though the usual deposits from MyPayrollHR’s client banks had not been made.

REVERSING THE REVERSAL

In response, Cachet submitted a request to reverse that transaction. But according to Slavkin, that initial reversal request was improperly formatted, and so Cachet soon after submitted a correctly coded reversal request.

Financial institutions are supposed to ignore or reject payment instructions that don’t comport with precise formatting required by the National Automated Clearinghouse Association (NACHA), the not-for-profit organization that provides the backbone for the electronic movement of money in the United States. But Slavkin said a number of financial institutions ended up processing both reversal requests, meaning a fair number of employees at companies that use MyPayrollHR suddenly saw a month’s worth of payroll payments withdrawn from their bank accounts.

Dan L’Abbe, CEO of the San Francisco-based consultancy Granite Solutions Groupe, said the mix-up has been massively disruptive for his 250 employees.

“This caused a lot of chaos for employers, but employees were the ones really affected,” L’Abbe said. “This is all very unusual because we don’t even have the ability to take money out of our employee accounts.”

Slavkin said Cachet managed to reach the CEO of MyPayrollHR — Michael T. Mann — via phone on the evening of Sept. 4, and that Mann said he would would call back in a few minutes. According to Slavkin, Mann never returned the call. Not long after that, MyPayrollHR told clients that it was going out of business and that they should find someone else to handle their payroll.

In short order, many people hit by one or both payroll reversals took to Twitter and Facebook to vent their anger and bewilderment at Cachet and at MyPayrollHR. But Slavkin said Cachet ultimately decided to cancel the previous payment reversals, leaving Cachet on the hook for $26 million.

“What we have since done is reached out to 100+ receiving banks to have them reject both reversals,” Slavkin said. “So most — if not all — employees affected by this will in the next day or two have all their money back.”

THE VANISHING MANN

Cachet has since been in touch with the FBI and with federal prosecutors in New York, and Slavkin said both are both now investigating MyPayrollHR and its CEO. On Monday, New York Governor Andrew Cuomo called on the state’s Department of Financial Services to investigate the company’s “sudden and disturbing shutdown.”

The $26 million hit against Cachet wasn’t the only fraud apparently perpetrated by MyPayrollHR and/or its parent firm: According to Slavkin, the now defunct New York company also stiffed National Payment Corporation (NatPay) — the Florida-based firm which handles tax withholdings for MyPayrollHR clients — to the tune of more than $9 million.

In a statement provided to KrebsOnSecurity, NatPay said it was alerted late last week that the bank accounts of MyPayrollHR and one of its affiliated companies were frozen, and that the notification came after payment files were processed.

“NatPay was provided information that MyPayrollHR and Cloud Payroll may have been the victims of fraud committed by their holding company ValueWise, whose CEO and owner is Michael Mann,” NatPay said. “NatPay immediately put in place steps to manage the orderly process of recovering funds [and] has more than sufficient insurance to cover actions of attempted or real fraud.”

Requests for comment from different executives at both MyPayrollHR and its parent firm ValueWise Corp. went unanswered, and the latter’s Web site is now offline. Several erstwhile MyPayrollHR employees reached via LinkedIn said none of them had seen or heard from Mr. Mann in days.

Meanwhile, Granite Solutions Groupe CEO L’Abbe said said some of his employees have seen their bank accounts credited back the money that was taken, while others are still waiting for those reversals to come through.

“It varies widely,” L’Abbe said. “Every bank processes differently, and everyone’s relationship with the bank is different. Others have absolutely no money right now and are having a helluva time with their bank believing this is all the result of fraud. Things are starting to settle down now, but a lot of employees are still in limbo with their bank.”

For its part, Cachet Financial Solutions says it will be looking at solutions to better detect when and if instructions from clients for funding its settlement accounts suddenly change.

“Our system is excellent at protecting against outside hackers,” Slavkin said. “But when it comes to something like this it takes everyone by complete surprise.”
