With years of experience in the technology industry, headlines about cyber attacks and data breaches stand out to me. Here’s your monthly roundup of the latest hacks and data breaches around the world. In this monthly series, I’ll share information and updates on the most recent hacks that I saw in the news, including causes, resolutions, and what you can do to protect your data.
This past month we saw a number of successful cyber attacks and data breaches across all industries, with healthcare, online platforms, and hospitality among those most affected.
Revealed in a recent financial filing, the personal information of about 45,000 patients of Rush University Medical Center was compromised in a data breach. Although no medical information was leaked, the data may include names, addresses, birthdays, social security numbers, and health insurance information. So far, none of the information has been misused. It is thought that this was caused by an employee improperly disclosing a file to an unauthorized third party site back in May 2018. Rush is offering anyone believed to be affected one year of free identity protection services. The healthcare industry is often a hot target for hackers. With so much highly valuable information kept on record of each patient, hospitals are one of the industries most likely to pay ransom to get back into an operational state. Read More.
14 properties owned and operated by Trump Hotels were reportedly affected by a data breach. The credit card information of guests between August 10th, 2016 to March 9th, 2017, may have been compromised. A data breach at a service provider included card payment details like names, numbers, expiration dates, and security codes. Trump Hotels recommends for those affected to actively observe their credit card activity and report and suspicious or fraudulent activity. Read More.
The huge data breach that hit Equifax in 2017, exposing the personal information of 148 million customers, is still affecting the company. A recent filing has reported that Equifax has spent about $1.4 billion recovering from the breach. The company suffered millions of dollars in fines and legal fees that could have been avoided with proper data protection. This story will always be an eye opening reminder of the importance of cybersecurity. Read More.
The encrypted message app owned by Facebook, reported that there is a vulnerability in their system giving hackers the ability to access users phones. The vulnerability has since been fixed but the cyber attackers were able to hack into a number of accounts through a WhatsApp phone call. Specifically targeted, was a human rights lawyer in London who received a WhatsApp call. The attempt was unsuccessful. Read More

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.
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.
Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.
Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
