Hyatt Hack: Major Data Breach

By NewsNo Comments
[vc_single_image source=”featured_image” img_size=”full”]

Hyatt Breach Affects 41 Hotels Worldwide

We would like to warn hotel guests of another credit card breach at Hyatt Group, the second since December 2015. On Thursday last week, 41 of its hotels spread across 13 countries confirmed unauthorized access to payment card information.

China had the worst breach with 18 hotels impacted, with three in North America. India, Japan and Saudi Arabia were also exposed.

Chuck Floyd, global president of operations for Hyatt Hotels Corporation, in an open letter to customers posted to its website “Based on our investigation, we understand that such unauthorized access to card data was caused by an insertion of malicious software code from a third party onto certain hotel IT systems.”

Hyatt suffered a similar breach affecting 250 hotels located in 50 countries back in 2015. In a prepared statement at the time Hyatt stated, “Hyatt has taken steps to strengthen the security of its systems, and customers can feel confident using payment cards at Hyatt hotels worldwide.”

Robert Brown, Director of Services for Verismic said, “It’s possible the steps taken by the Hyatt group back in December 2015 are still being deployed throughout the organization, especially if those systems are dispersed around the globe and not connected by a common network. When choosing your systems management toolset, you need to implement the solution which is secured using 2048bit certificates and two factor authentication but also works regardless of where the endpoints are located.

This is something built into the DNA of Syxsense, to operate securely as long as there is an internet connection. Using Syxsense, these endpoints could have been protected within a couple of weeks.”

October Patch Tuesday: Silent But Deadly

By News, Patch Management, Patch TuesdayNo Comments
[vc_single_image source=”featured_image” img_size=”medium”]

Should Third-Party Really Be your Second Priority?

If you have a patching strategy delivering Microsoft updates on a routine basis, you should extend that capacity to include third-party updates.

Just a couple weeks ago, we discovered a massive compromise in one of the world’s largest business and personal computer utilities, “CCleaner” by Piriform.

Version 5.33.6162 was released with injected malicious code which would expose any system to hackers remotely gaining access to that system. To make matters worse, CCleaner does not come with an automatic update capability so remediating these issues requires a toolset which can remotely deploy or patch third-party software. Piriform said that Avast, its new parent company, had uncovered the attacks on Sept. 12, with a new, uncompromised version of CCleaner being released the same day.

Robert Brown, Director of Services for Verismic said, “Your patch management strategy must include both the operating system and any software or third-party updates to be reassured of your environment’s safety. Deploying only Windows updates is not closing the holes used by hackers in the current wave of ever increasing sophisticated hacks.

Syxsense includes both Microsoft, Linux and the most popular third-party vendors so you can be reassured everything is covered.”

What takes 206 days?

Cyberattacks are an increasingly serious risk for organizations, but many executives believe their organization won’t be targeted. They claim their organization is too small to be on the attackers’ radars or that they have nothing worth stealing.

Many cybercriminals are indiscriminate in their attacks and can always find something of interest. However, companies that believe they’re safe may already be penetrated – they just don’t know it yet.

[dt_default_button link=”url:https%3A%2F%2Fwww.syxsense.com%2Fsyxsense-trial%2F|||” size=”big” button_alignment=”btn_center”]START FREE TRIAL[/dt_default_button]

A study found that US companies took an average of 206 days to detect a data breach. This is an increase on the previous year (201 days) where a survey showed 20 percent of employees showed a lack of awareness for safe social media posting, choosing risky actions such as posting on their personal social media accounts. Data breaches are contained sooner if they’re detected by a staff member when conducting routine assessments of potential vulnerabilities within their organization.

“This is why it is important to have a proactive stance when it comes to patch management,” said Brown. “How long will it take before you realize you have been compromised?”

Ransomware is the fastest growing security threat, yet most companies are unprepared to deal with it, says a new study. Companies and government agencies are overwhelmed by frequent, severe attacks, according to the 2017 Ransomware Report commissioned by Cybersecurity Insiders and conducted by Crowd Research. That illustrates why ransomware damages are expected to hit $6,000,000,000 this year.

September Patch Tuesday: Escaping the Equi-Hack

By News, Patch Management, Patch TuesdayNo Comments
[vc_single_image source=”featured_image” img_size=”medium”]

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.

[vc_single_image image=”13032″ img_size=”200×200 px”]

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.

March Patch Tuesday: Patching Chaos

By News, Patch Management, Patch TuesdayNo Comments
[vc_single_image source=”featured_image” img_size=”medium”]

The Eye of the Patch Storm

Two months have passed since the beginning of the year where we saw one of the smallest releases of patch content for the past couple of years, to then having an entire baseline cancelled at the last minute in February.

Some IT managers may have counted their lucky stars for the reduction in their workload so far this year – that is until they see this massive release.

Microsoft have released eighteen updates this month, nine are rated Critical with the remaining rated Important. Last week Microsoft also released 17 KB updates covering Office version 2013 and 2016. Full details of that release can be found here.

Last year we raised our concerns about rolling patches together, and last month only two months since Microsoft adopted this strategy were our concerns realized. Because of a single bad patch, the entire baseline was cancelled. 

Don’t get us wrong, we understand the benefit of rolling content into single cumulative updates, but we also appreciate the level of testing needed to ensure a safe combination of updates when rolling them together. That same level of care should be adopted when deploying updates in your environment to ensure bad updates do not cause business outages.

A school study at the University of Maryland was the first to quantify the near-constant rate of hacker attacks of computers with Internet access—every 39 seconds on average.

[vc_single_image image=”11077″ img_size=”medium”]

Robert Brown, Director of Services said “Perception as to the current threat to a company’s network should not be founded on the content released by vendors such as Microsoft alone. There are multiple perimeters you can secure to protect your assets, but remember to also look at the tool you are using to secure your environment. In the past few weeks, IBM have released over 20 security updates for their premise and cloud based patch management tools, meaning your toolset should have a perimeter of its own.”

According to the SANS Institute, 95 percent of all attacks on enterprise networks start with a successful spear phishing attack. Full details of this article can be found here.
