OnlyMyEmail Blocks More Spam in VBSpam Competition

Friday, April 8th, 2016

For a 32nd test in a row, OnlyMyEmail’s MX-Defender blocked more spam than any other filtering system competing in the Virus Bulletin VBSpam Challenge.

During the latest competition, which ran for just over two weeks, OnlyMyEmail accurately blocked more spam than all other spam filters, not missing even a single spam email out of 225,571 messages, 216,053 of which were spam. This was the largest test corpus in 6 years of competitions an OnlyMyEmail alone stopped 100% of the spam.

In addition, OnlyMyEmail did not create a single false-positive result (blocking of legitimate emails) during the test, resulting in another VBSpam+ award.

By comparison, well known solutions performed much worse, with Kaspersky missing 145 spam emails, Sophos allowing 249 and SpamHaus failing to capture 3,510 emails from the exact same live feed of messages.

The results from Virus Bulletin’s VBSpam Challenge continually document that OnlyMyEmail’s MX-Defender is decisively superior to any other spam defense available today, having stopped a far higher rate of spam than any other filter tested since the VBSpam Competition began in 2009.

In all, over the years, OnlyMyEmail has significantly outperformed a total of 39 other systems including hardware appliances, software programs and other Software as a Service (SaaS) solutions.

Quoting from the VBSpam review:

“OnlyMyEmail’s catch rate hasn’t dipped lower than 99.99% for the past four years. On occasion it has even been a full 100% – as it was in this test”

The full list of competitors to date, (many have dropped out) includes:

Anubis Networks, Axway MailGate, BitDefender, CronLab Anti-Spam, Eleven eXpurgate, ESET, FortiMail, GFI MailEssentials, GFI VIPRE, Halon Security, IBM Lotus Protector, Kaspersky Anti-Spam, Libra Esva, Mailshell, McAfee Email Gateway, McAfee EWS, McAfee SaaS, Messaging Architects M+ Guardian, MessageStream, modusGate, Netmail Secure, NoSpamProxy, Pro-Mail, Scrollout, Sophos Email Appliance, SPAM Fighter, Spamhaus, Spamhaus ZEN+DBL, SpamTitan, Spider Antispam, Symantec Brightmail, Symantec Messaging Gateway, SURBL,The Email Laundry, Vade Retro, Vamsoft ORF, Webroot, and ZEROSPAM.

ADP Payroll Invoice Spam/Virus

Monday, January 27th, 2014

There’s a very successful spam campaign out now spoofing legitimate ADP payroll invoice emails. They most commonly arrive as:

Subject:     Payroll Invoice
From:     “payroll@adp.com”

In reality, they come from previously infected personal computers spanning the globe.

An example of the above:

‘from 60-240-131-86.static.tpgi.com.au ([60.240.131.86])

(envelope-from <photojournalistvi@wetleather.com>)

It doesn’t take a trained email professional to realize that’s not ADP emailing.

Google Docs Phishing Frauds

Saturday, March 23rd, 2013

It seems that almost every tool Google provides is readily adopted by spammers and scammers alike.  Not a day goes by that we don’t see spam and Phishing fraud and other identity theft emails from hacked Gmail and Google Groups accounts and often abusing systems such as Google Docs.

The ubiquity of these free services makes for the perfect no-cost social engineering platform for hackers to use for launching their attacks.

A current Phishing campaign uses stolen Gmail accounts to steal the credentials to other email accounts, allowing spammers to increase their spam volume day over day.

The most common email circulating now comes with a subject that references the sharing of a file though “Google Docs” and often has a subject line of simply:

Subject:     Important Document

Since the email comes from a previously hijacked account, the recipients will typically recognize the sender’s address which makes it more likely that they will be taken in by this fraud:

The Better Business Bureau Trojan Horse

Thursday, February 21st, 2013

With the fake Better Business Bureau Trojan Horse campaign, we find yet another infectious email that is socially engineered so well, that users often release such messages from quarantine; even after spam filtering has clearly identified the emails as a Virus carrying Trojan Horse.

The emails typically arrive with spoofed headers such as:

Subject:     FW: Complaint Case 091921
From:     “Better Business Bureau” <Kerri_Rucker@newyork.bbb.org>

In order to appear legitimate and to try and evade simple spam filtering systems, the Complaint Case number will be randomized, and the spoofed sending email address will vary as well.

The content will include vague yet serious sounding allegations, such as:

The Better Business Bureau has received the above-referenced complaint from one of your customers regarding their dealings with you. The details of the consumer’s concern are included on the reverse. Please review this matter and advise us of your position.

Your order is awaiting verification! – Staples Virus

Monday, January 14th, 2013

Sometimes spam, viruses and Trojan Horse emails are so convincing that they manage to trick users even after spam filtering has clearly identified the emails for their true nature.

The recent spate in bogus “Your order is awaiting verification!” emails claiming to be from Staples office supplies is a pretty good example.

Despite being clearly marked as viruses, we’ve seen many users attempt to resend these blocked messages to themselves, apparently believing that our blocking these messages represents a false-positive result on the part of our filtering, whereas the opposite is the case.

The emails typically arrive with spoofed headers such as:

Subject:     Your order is awaiting verification!
From:     “Staples Advantage Orders” <Order@staplesadvantage.com>

Introducing Your US Department of Justice and FBI Victim Notification System

Thursday, January 19th, 2012

Here’s something we really don’t see every day….

We recently received an email claiming to be from the U.S Department of Justice Victim Notification System (VNS)

Subject:     US Department of Justice Victim Notification System
From:     Courtney Walker <fedemail@vns.usdoj.gov>
To:     Business Representative <address>

Our typical “common sense” check for email Phishing Fraud starts with the obvious:

  1. Overly serious/threatening Subject line…. check!
  2. Human sender doesn’t match email address…. check!
  3. Impersonal and generic salutation… check!

The email itself open with:

DO NOT REPLY TO THIS EMAIL.

Rejected ACH payment – Virus/Fraud

Monday, August 15th, 2011

Look out for fraudulent emails spoofing “The Electronic Payments Association” that are arriving as:

From:     risk_manager@nacha.org
Subject:     Rejected ACH payment

In reality these messages are from previously infected personal computers from across the globe:

from [122.168.251.32] (helo=ABTS-mp-dynamic-032.251.168.122.airtelbroadband.in)

These messages include a fictional warning that includes content such as:

New Skype Has Been Releases ! Upgrade Now

Saturday, July 16th, 2011

Mailboxes are now receiving fake Skype upgrade spam sent from hijacked Rhapsody.com mail servers.

The current campaign arrives as:

Subject:     New Skype Has Been Releases ! Upgrade Now
From:     “Skype” <newsletter@news.skype.com>

In an interesting twist, the spammers involved appear to have hacked and are in control of Rhapsody.com mail servers as the samples we’ve reviewed so far are actually from:

  • mta900.e.rhapsody.com ([63.211.90.40]
  • mta902.e.rhapsody.com ([63.211.90.42]
  • mta903.e.rhapsody.com ([63.211.90.43]
  • mta904.e.rhapsody.com ([63.211.90.44]
  • mta905.e.rhapsody.com ([63.211.90.45]
  • etc., etc.
