Cybersecurity Threat Breakdown [Cathay Pacific + Pentagon]

October 30, 2018

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.

Over the last several weeks, we saw what has now become the usual list of successful cyber attacks and data breaches across all industries, with government entities, healthcare and retail dominating the list.    

Cathay Pacific

The Hong Kong based international airline, Cathay Pacific, confirmed a data breach that exposed personal data of 9.4 million people. The hackers were able to access private user information including: phone numbers, dates of birth, passport and government ID numbers, and 27 credit card numbers. The airline plans to contact those affected by the data breach providing steps to protect themselves. If you ever find yourself in a similar situation, it is important to monitor your personal accounts for any fraudulent activity. Read more.  

Ripple

A user of the Australian cryptocurrency company experienced a personal loss after having 100,000 units of XRP, worth about $318,000, stolen out of his account. A 23 year old woman was charged with the theft. She stole the money by hacking into his Hotmail account which was linked to his Ripple account. Neither the Hotmail account nor the Ripple account had two-step verification, which could have prevented this incident. Two-step verification means a system requires two forms of proof you have access to that account before obtaining access, some sending you a code via text message. This is an important lesson to not only protect your company’s data but also your personal data as well. Read more.

Pentagon

The Department of Defense reported that the Pentagon recently experienced a data breach, but they did not provide many details on the situation. What is know is that travel records, including personal information and credit card data, was stolen for about 30,000 individuals. The DoD cannot identify the source of the data breach yet, but they are working towards finding the source and exact date it occurred. This is a great example of how advanced hackers are to be able to hack into the DoD database and successfully hid the traces of their attacks. Until the source and exact date can be confirmed, it leads the DoD more vulnerable to other attacks. It can be very difficult to protect against the unknown Read more.

North Korea

FireEye, a US security firm, has brought attention to a North Korean group that has stolen millions of dollars by hacking into the computer systems of banks around the world. This is a very sophisticated hack that is still occurring and is part of a wider set of hacks that has affected at least 11 countries. The hacking group known as APT38, was also a part of the WannaCry virus and stole $81 million dollars from Bangladesh’s central bank. The US department of Homeland Security has warned of the use of malware by these North Korean hackers in fraudulent ATM cash withdrawals in Asia and Africa. North Korean hackers are something to be aware of as they are very knowledgeable and powerful at what they are doing. Be sure to take all measures to protect your data. 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.
