📝 Podcast Summary
The Reality of Cybersecurity: Even Major Retailers Aren't Immune to Hacks
A major retail outlet got hacked and led to the sale of credit cards on the black market. The outlet found out from an email of their credit card brand and hired a consulting firm, Kroll to investigate their network. Incident responders, like Courtney Dayter and Matt Bromiley,both used to working on larger cases and specifically cases involving finance and retail, were the team hired to find, isolate, and fix the problems. With thousands of stores in the US and many more all across Europe and Asia, the outlet had both their online and physical stores' computers connected to the network, which made the breach easier. This case showcases that even the largest companies in the world can be victims of hacks.
Incident Response for a Large Retail Company
When conducting incident response for a global retail company, starting with two different approaches, which are understanding any leaked data and checking for any breach possible, deploying the necessary technical tool like Carbon Black for end-point monitoring and analysis, and then spreading throughout the environment. The monitoring software and antivirus at the stores couldn't detect anomalies, but identifying a set of computer systems acting suspiciously and taking them offline helped to track down thousands of malicious files with encrypted data. Using logs and tracking the IP addresses, they discovered 1,200 compromised systems and identified specific malware variations. The malware scraped data from memory and sent it to a central repository system, while writing to an output file with specific extensions.
Retail Company's Massive Credit Card Breach Linked to Global Cybercrime Ring
Thousands of cash registers in a retail company were compromised with malware that scraped every credit card processed and leaked the data out of the network. Criminals used the stolen card data to withdraw cash from ATMs or buy gift cards to launder money, making serious cash off the retail company. The team found the same type of infrastructure in North America, Europe, and Asia Pacific. The investigators feared the amount of data stolen and accessed could be in the millions of credit card numbers. Companies should have robust cybersecurity measures and regularly monitor their systems to prevent such malicious activities and minimize the damage in case of a breach. Customers should also be vigilant and monitor their credit card statements for any unauthorized transactions.
Uncovering a New Variant of Tiny POS Malware and Its Impact on Point of Sales Systems
A new variant of Tiny POS malware was uncovered by the team that was directly writing over the wire to central pivot points used by attackers for card-scraping. Antivirus installed on registers weren't able to pick up this malware as it was less than 6 KB in size. Surprisingly, not only 80% of point of sales registers but also back of house systems had malware and were being scraped for data. Delivering such news to the client is never easy, and the team had to call them with the shocking discovery. The lawyers play a crucial role in verifying the findings and processing it, but there's always some hesitancy to avoid raising false alarms.
Understanding the extent of a credit card data breach and mitigating its impact
In case of a credit card data breach, it is essential to quantify the extent of the damage, which includes determining the size and scope of the breach along with the exact period for which the data has been compromised. Digital forensics can help in understanding the duration and origin of the breach and whether it was a targeted attack or a result of phishing. Phishing is when a hacker targets an employee to click on malicious links or documents that can infect the system and provide access to hackers. Credit card companies ask for details and proof in case of a breach and identifying and removing duplicate and invalid card numbers from the exposed data is crucial.
Protecting Data Through Vigilant Monitoring and Patching
Malware attackers can gain access to historical unencrypted data and use it to steal credit card information from years ago. Taking servers offline and patching network holes can help stop attackers from re-entering, but companies must also be vigilant in tracking down all back doors and phishing campaigns used by attackers. The speed at which attackers can re-compromise multiple machines speaks to how long they have been in the network, highlighting the importance of regularly monitoring network activity to detect and prevent intrusions. Having a dedicated team to find and track down potential breaches is essential in protecting company and customer data, even if breaches are inevitable.
Preventing Malware Attacks with Proper Network Security.
Proper network security measures, such as password changes and encryption, can prevent malware attacks. Back doors installed by hackers enable them to gain access to systems and control them even after they have been removed. The team was able to track the hackers' movements and quickly remediate the attack, but attribution to the person responsible for the attack is often difficult. Mapping out the attacker's global infrastructure allowed the team to gain control over the attack and prevent any more credit card information from being stolen. The team's findings were shared with the company to improve their security and prevent similar attacks in the future.
Asia Top Target for Hackers with Massive Data Breach
Asia had the highest number of unique back doors installed on it, with almost every system compromised. The compromise started in Southeast Asia. The final number of credit cards stolen was almost 100,000. These cards are likely to be sold in bulk somewhere for $10-$100 each, potentially making the hackers a million dollars. The breach was not as heavily covered by news outlets as previous breaches like Home Depot and Target. However, this breach severely impacts the individuals whose cards were stolen, and it falls on the company to work with banks and credit card companies to issue new cards.
The Importance of Cybersecurity: Stories of Cyber Attacks and Prevention Efforts
The consequences of cyber attacks can be severe, as seen in Tom's story where his card data was stolen and used fraudulently, resulting in his business being negatively impacted, causing major interruptions in his life. However, there are security professionals like Courtney and Matt who work to detect and report new strains of malware to antivirus companies, helping to prevent future attacks. The importance of cybersecurity cannot be overstated, and it is crucial to stay informed about the latest threats and take steps to protect yourself and your business. Growing the awareness of the importance of cybersecurity is a collective effort and everyone can play a part in promoting it to others.
