Money Well Spent

Every dollar of fraud to merchants and firms in the retail and financial services sector is estimated to cost $2.66 on average, said a new fraud report.

The LexisNexis Fraud Multiplier estimates the total amount of loss a business incurs, based on chargebacks, fees, interest, merchandise replacement and redistribution.

The study also investigates fraud costs as a percentage of revenues, as reported by survey respondents, to be nearly 2 percent (1.90 percent) across retail, e-commerce, financial services and digital lending businesses. Businesses that sell digital goods and/or conduct transactions primarily through remote channels take an even harder hit to their bottom line at 2.51 percent of revenues.

Robert Brown, Director of Services for Verismic says, “It’s astonishing how much money is being lost because critical systems are not being kept up to date. Updating critical systems is so easy using Syxsense. We recommend starting a trial to see how it can work for you.” Full article can be found here.

As recent as last Wednesday, a U.S. government website was hosting malicious ransomware. It has been wildly speculated that either the site was hacked, or it possibly stores attachments from government officials’ emails and the downloader was archived.

The ransomware had similarities to the Blank Slate spam campaign which earlier this year was spreading Cerber. Emails in that campaign contained only a double-zip archive with the second containing either a malicious JavaScript file or a malicious Microsoft Word document. The emails contain no text, and experts believed then that all of this combined to evade detection.

Researcher Ankit Anubhav of NewSky Security tweeted the discovery Wednesday, and within hours, the malware link was taken down. It’s unknown whether anyone was infected through the site, full article can be found here.

Check your Equifax Credit Report and Score Now

Victims of the massive Equifax breach may have to wait days to find out if they were impacted. Americans who either applied for new jobs, loans, or just wanted to check their credit score via Equifax are having a difficult time getting answers as to whether they are part of the breach of 143 million records that occurred Thursday.

Details of how this breach happened is still very unclear, however with companies suffering the same fate over the past year, the root cause is likely to be via a sophisticated cyberattack exposed using vulnerable software or operating systems.

Robert Brown, Director of Services for Verismic says, “We recommend clients download our ‘5 Biggest Patch Mistakes‘ whitepaper.

Microsoft published its monthly security updates on September 12, 2017. Microsoft addressed 81 vulnerabilities in Microsoft Windows, Microsoft Internet Explorer, Microsoft Edge, and Microsoft Office. The vulnerabilities could allow an attacker to execute arbitrary code, gain elevated privileges, bypass security protections, view sensitive information, or cause a denial of service. Full details of the complete Security Update Guide can be found here.

Microsoft Updates

We have chosen a few updates to prioritize this month. This recommendation has been made using evidence from industry experts (including our own), anticipated business impact and the independent CVSS score for the vulnerability. The independent CVSS scores used in the table below range from 0 to 10. Vulnerabilities with a base score in the range 7.0-10.0 are High, those in the range 4.0-6.9 as Medium, and 0-3.9 as Low.
