Cybersecurity Threat Breakdown - April 2018

May 17, 2018

Facebook

Here’s your monthly roundup of the latest hacks and data breaches around the world. In this new monthly series, we’ll share information and updates on the most recent hacks that have made headlines, including causes, resolutions, and what you can do to protect your data.

April saw what has now become the usual list of successful cyber attacks and data breaches across all industries, with healthcare and retail dominating the list.    

Panera Bread

On April 3, 2018, it was reported that Panera Bread may have exposed the personal data of millions of customers who made purchases via their website. No full credit card numbers were among the information stolen, however names, addresses, email addresses, and birthdays were, all information that can easily lead to identity fraud. While Panera admits to 10,000 customer records being stolen, security expert Brian Krebs believes the number to be much higher, and that he noticed the breach 8 months ago.  Read More.

Hudson’s Bay Co.

The Canadian based company which is the parent company of Saks Fifth Avenue and Lord & Taylor announced that they were recently hit by a data breach that likely compromised millions of customer card information. They were targeted by the criminal group JokerStash, who sells credit card information on the black market. While it is still too early to tell how many cards were affected, this is shaping up to be one of the biggest payment card hacks in the last couple years. Read More.

Careem

A popular ride sharing service in the Middle East experienced a major data breach of more than 14 million of their customers. While there is no evidence that credit card information was stolen, personal information like name, email address and trip information was compromised. Read More.

Center for Orthopaedic Specialists

A mult-office medical group in California experienced a ransomware attack on their computer systems.  Malware software was used to gain access to the network and encrypt patient data, however before the data was lost permanently, their IT vendor was able to take the system offline permanently. While it is believed that no patient information was compromised, the COS group is working to inform patients and offer them free identity protection services for the next two years. Read More.

Under Armour

In one of the largest breaches so far this year, Under Armour, the owner of the popular fitness app, MyFitnessPal, announced that over 150 million users had their personal data stolen. While no government-issued identifiers like social security numbers were stolen, the hackers now have valuable information into the habits and whereabouts of users. Under Armour says no financial data was stolen, but encouraged users to change their passwords immediately to a more secure password. Read More.

And even though these events happened prior to April 2018, they still dominated the headlines throughout the month.

Facebook - Cambridge Analytica

While not a true data breach, the Facebook-Cambridge Analytica scandal still warrants some attention due to the highly sensitive nature of the information shared. Facebook recently announced that it suspended 200 apps after the scandal was revealed, due to ongoing investigations over improper use of personal data. WIth GDPR only days away, it’s likely that we’ll see a resurgence in this story as data privacy and security become a hot topic in Europe. Read More.

Equifax

Equifax has spent over $242.7 million on it’s data breach to date. After last September’s massive data breach, the company has spent an additional $45.7 million in the first quarter of 2018 to update IT infrastructure, applications, and security. Read More.

Heartbeats Packets Inside the Bypass TAP

If the inline security tool goes off-line, the TAP will bypass the tool and automatically keep the link flowing. The Bypass TAP does this by sending heartbeat packets to the inline security tool. As long as the inline security tool is on-line, the heartbeat packets will be returned to the TAP, and the link traffic will continue to flow through the inline security tool.

If the heartbeat packets are not returned to the TAP (indicating that the inline security tool has gone off-line), the TAP will automatically 'bypass' the inline security tool and keep the link traffic flowing. The TAP also removes the heartbeat packets before sending the network traffic back onto the critical link.

While the TAP is in bypass mode, it continues to send heartbeat packets out to the inline security tool so that once the tool is back on-line, it will begin returning the heartbeat packets back to the TAP indicating that the tool is ready to go back to work. The TAP will then direct the network traffic back through the inline security tool along with the heartbeat packets placing the tool back inline.

Some of you may have noticed a flaw in the logic behind this solution!  You say, “What if the TAP should fail because it is also in-line? Then the link will also fail!” The TAP would now be considered a point of failure. That is a good catch – but in our blog on Bypass vs. Failsafe, I explained that if a TAP were to fail or lose power, it must provide failsafe protection to the link it is attached to. So our network TAP will go into Failsafe mode keeping the link flowing.

Glossary

  1. Single point of failure: a risk to an IT network if one part of the system brings down a larger part of the entire system.

  2. Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.

  3. Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
