06 Nov Security Report – 6 Nov 2026

Posted at 15:36h in Security Breach, TCT News by

Cryptocurrency, such as Bitcoin, has become increasingly popular, but it has also created opportunities for cybercriminals. Scammers may promote fake investments through social media, email or messaging apps, promising high or guaranteed returns. They may also create convincing websites or apps that appear to show an investment growing, when in reality the money or cryptocurrency has been transferred directly to the scammer.

Be cautious of unexpected cryptocurrency opportunities, pressure to act quickly or requests to transfer funds to an unfamiliar digital wallet. Never share passwords, multi-factor authentication codes, private keys or cryptocurrency recovery phrases, and never give an unknown person remote access to your computer or phone. Cryptocurrency transactions can be difficult to reverse, so take the time to independently verify who you are dealing with before sending money.

 

Recent Breaches

Asia & Pacific – Amadeus –Aerospace & Defense

Exploit: Supply Chain Attack

Risk to Business: Moderate: A major supply chain breach sent shockwaves through the aviation sector, with multiple airlines across Asia reporting unauthorised access to customer data following a vulnerability in travel tech giant Amadeus. Amadeus is a global travel tech company that runs the systems airlines use for reservations, ticketing and check-in. On October 1, the company disclosed a vulnerability in its travel booking display environment, stating that no ransomware actors had exploited it and that no payment or financial data was exposed. However, major Asian airlines including Japan Airlines, Korean Air, Asiana Airlines and Malaysia Airlines have since notified customers that their personal information may have been exposed because of the breach. Japan Airlines confirmed approximately 92,000 customers of Japan Airlines and Japan Transocean Air were affected, while All Nippon Airways reported approximately 37,800 affected customers. Korean Air, Asiana Airlines and Malaysia Airlines have all reported potential exposure of customer data without disclosing specific figures.

United States –Binance – Finance 

Exploit: Nation-State

Risk to Business: Moderate: The FBI attributed the largest cryptocurrency heist on record to North Korean hackers after more than $6.3 billion was stolen from the world’s biggest cryptocurrency exchange, Binance. On October 29, 2026, cybercriminals stole more than $6.3 billion in virtual assets from Binance. The company’s initial investigation suggested that a compromised laptop belonging to a DevOps engineer may have enabled unauthorised withdrawals, though additional breach points were subsequently identified, meaning the full attack path remains under investigation. Meanwhile, the FBI has linked the attack to TraderTraitor, a state-sponsored North Korean cybercrime and advanced persistent threat (APT) group with a known history of targeting the cryptocurrency sector. The attack is the latest in a growing wave of cyberattacks targeting the cryptocurrency sector. A coordinated cyberattack targeting popular Bitcoin wallet COLDCARD reportedly resulted in estimated losses of more than $100 million in early August.
