It says, &#8220;Our bank has changed. Please send this month&#8217;s payment to the new account.&#8221; This is a vendor invoice scam, and the logo and tone often look right.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The official name is business email compromise, or BEC. The <a href=\"https:\/\/www.ic3.gov\/CrimeInfo\/BEC\" target=\"_blank\" rel=\"noopener\">Internet Crime Complaint Center (IC3)<\/a> describes it as a scam that targets both businesses and individuals who transfer funds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We see why it works around Pierce County. Small offices pay the same few vendors again and again. Everyone is busy, and a routine request gets a routine yes. That is exactly what the scammer is counting on.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How the vendor invoice scam works<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">IC3 says the scam is often carried out when someone breaks into a real business email account. They do it through social engineering (fooling a person) or computer intrusion (breaking into the system).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In plain words, there are two common versions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A real account is taken over.<\/strong> The scammer logs in to your vendor&#8217;s actual email and sends you a real-looking invoice with new bank details.<\/li>\n\n\n\n<li><strong>A look-alike address is used.<\/strong> The email comes from an address that is almost right, with a letter swapped or a different ending.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Either way, the goal is the same. They want your payment to land in their account instead of your vendor&#8217;s.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The first version is the nasty one. The email really does come from your vendor&#8217;s address. A quick glance at the sender won&#8217;t save you. That is why the fix is a check outside of email.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why a real-looking email isn&#8217;t proof<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Scammers do homework. They may read old threads and copy the way your vendor writes. They may time the message right when an invoice is due.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Phones make it harder. IC3 advises you to check the sender&#8217;s address, &#8220;especially when using a mobile or handheld device.&#8221; Phone screens often show only a friendly name, not the full address behind it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IC3 also suggests setting up your computers so full email extensions can be viewed. That means the whole address, not just the name. It takes a minute to turn on, and it makes odd addresses easier to spot.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The one rule that helps most<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">IC3&#8217;s main advice is simple: use a second channel, or two-factor authentication, to verify requests for changes in account information with the intended recipient.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A second channel just means a different way of reaching the person. If the request came by email, confirm it another way.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Call the vendor at a phone number you already had. Use one from an old invoice, your contract or your own contacts.<\/li>\n\n\n\n<li>Do <strong>not<\/strong> use the phone number in the new email. The scammer wrote that too.<\/li>\n\n\n\n<li>Ask for the change in writing after you confirm it by phone, and keep both on file.<\/li>\n\n\n\n<li>Make it a habit that no one changes vendor payment details on an email alone.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This works because the scammer usually controls the email thread, not your vendor&#8217;s phone line. It is a slow step on purpose. A few minutes of friction costs far less than a lost payment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A written rule also takes the pressure off the person who gets the odd request. It is the same idea as an office rule for gift card texts from a fake boss.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">If you already sent the money<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Don&#8217;t wait and hope. IC3 says to contact your bank (the originating financial institution) as soon as you recognize the fraud. Ask for a <strong>recall or reversal<\/strong> of the payment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IC3 also says to ask for a <strong>Hold Harmless Letter or Letter of Indemnity<\/strong>. Getting those documents quickly &#8220;may reduce or eliminate&#8221; your losses, in IC3&#8217;s words. That is no promise, but speed clearly helps.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then file a detailed complaint at <a href=\"https:\/\/www.ic3.gov\/CrimeInfo\/BEC\" target=\"_blank\" rel=\"noopener\">IC3<\/a>. IC3 says it is vital to fill in every required field, including the bank information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Also tell your real vendor. Their email account may be compromised, and they will want to know. And change the password on your own email, in case the scammer got in there too.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Lock down the email side too<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The scam depends on email accounts being open to a break-in. A few basics make that harder:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Turn on multi-factor authentication (a second step, like a phone prompt, when you sign in) for every email account.<\/li>\n\n\n\n<li>Use a different, long password for email than for anything else.<\/li>\n\n\n\n<li>Watch for mailbox rules you didn&#8217;t create, like auto-forwarding to an unknown address.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">We covered more of the basics in <a href=\"https:\/\/rainier-it.com\/blog\/5-common-cybersecurity-mistakes-small-businesses-make\/\">5 Common Cybersecurity Mistakes Small Businesses Make<\/a>. IC3 also suggests watching your financial accounts regularly for oddities such as missing deposits. A quick weekly look at your bank activity is a good habit.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What to do this week<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Write down the rule:<\/strong> any change to a vendor&#8217;s bank details must be confirmed by phone, using a number you already had.<\/li>\n\n\n\n<li><strong>Tell whoever pays the bills,<\/strong> including part-time helpers and your bookkeeper, about the rule.<\/li>\n\n\n\n<li><strong>Make a short list of your regular vendors<\/strong> with trusted phone numbers, kept somewhere other than email.<\/li>\n\n\n\n<li><strong>Turn on multi-factor authentication<\/strong> for every email account in the office.<\/li>\n\n\n\n<li><strong>Show full email addresses<\/strong> on your computers and phones, so odd senders are easier to spot.<\/li>\n\n\n\n<li><strong>Save your bank&#8217;s fraud line<\/strong> where staff can find it fast, in case you need a recall.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you want a second pair of eyes, we&#8217;re happy to help.
