Fraud Alert - E-Mail Scams

  • Fraud Alert - E-Mail Scams (This Page)

There have been some scams pretending to send e-mail in our name, including

  • Asking that non-existent invoices be paid
  • Requesting changes to ACH or EIN information on record
  • Requesting other business transactions

These are not from us nor sent from our servers. Concerning our correspondence:

  • Our e-mail addresses are "@sisweb.com". Beware of other domain names, including free email accounts (gmail) and misspellings, "Reply-To" addresses that differ from "From" addresses, and our email address embedded in the person's name field that actually has another email, like " 'My Name <example@sisweb.com>' <example@otherdomain.com>".
  • Our phone numbers are 908-788-5550 (NJ office) or 215-766-9998 (PA machine shop). Our fax is 908-806-6631. We do not use other numbers.
  • Links in our e-mail only go to our web site www.sisweb.com, not to some other web site.
  • Our invoices are PDF attachments only, not Word or ZIP attachments or links to other sites.
  • Our e-mail server uses SPF and DKIM to guard against forged e-mails in our name, but some spam filters unfortunately do not fully utilize this, or may display only an SPF fail warning in the e-mail headers or warn coming from some other country or antivirus might strip an attachment.

If in doubt, call us at 908-788-5550 (NJ office). Please forward any suspicious e-mails to us and include full headers of the e-mails. Thank you.

Some examples of fraudulent e-mails are below.

Where action is required by yourselves, we kindly request each query is responded to quickly, preferably within 48 hours. This will help prevent potential payment delays - unfortunately payment cannot be made until queried invoices are reviewed and cleared for payment in accordance with our agreed terms and conditions. Below is a new queried invoice with the reasons why we have placed it in query. Thank you for your business - we appreciate it very much. ### ### Contact Number: 738 501-2343 ext.7 eMail:###@sisweb.com
