Several behaviors or activities might raise red flags and may be deemed suspicious, which could result in a credit card being blocked or flagged by the credit card issuer or financial institution. A few examples of suspicious behavior are: Unusual buying Patterns
A sudden large transaction or a significant increase in spending when compared to the usual behavior of the cardholder can raise suspicion.
Unrecognized Transactions
Fraud may be evident if you see any transactions on your card statement that are not familiar or unauthorised and that the cardholder doesn't agree with.
Multiple declined transactions
If you've got a record of positive transactions, but the cardholder is experiencing multiple failed or declined transaction in a short amount of time, this could be an indication that there's a problem.
Geographic Anomalies
If you observe transactions from locations that are far away from your typical shopping destinations or multiple transactions in the same time across different geographic places, it could raise suspicion.
Purchase types that aren't normal
Unusual purchases, especially for costly items that are not compatible with the habits of the cardholder's spend, can be flagged as suspicious.
Uncommon Online Behavior
Unexpected or unusual online activity, such as failed logins multiple times, account changes or unusual attempts to log in, may suggest the possibility of unauthorized access.
Uncharacteristic Card Usage-
Any instance where an account with a credit or debit card is used in a different manner than its normal pattern of use, for instance, suddenly using it for international transactions, despite the previous used only locally, could be a sign of fraud.
Rapid Cash Advances, or Transfers
Large cash advances or transfers that are out of the ordinary for the cardholder's spending behavior may cause alerts.
Frequent Card Transactions that are Not Present
The unusually high volume of transactions (online, over the phone or any other method) that involve cards that are not held with prior experience could raise suspicion.
Problems with Identity Verification
Especially in cases of additional verification, it could be suspect if you're having problems verifying the identity of your cardholder during a transaction.
These actions could trigger fraud detection systems as well as monitoring systems at the card issuer, which could cause them to investigate, block the cards temporarily, or confirm the legitimacy of transactions.
What Is My Credit Card's Status Being Blacklisted Mean?
If a credit or debit card is placed on a “blacklist”, it means that certain transactions are temporarily prohibited until the issue has been solved or confirmed. The reasons for a card being placed on blacklists can differ, and could include:
The card can be blocked for security purposes is possible in the event of suspicions of fraud.
Security concerns. The card could be flagged in the event of signs of potential breach. For example, an unauthorised access to the card or a breach of data that relates to the card, or unusual spending patterns.
Identity Verification Problems- Issues that require verification of the identity of the person who is using the card during transactions could result in temporary suspension of the card particularly when additional confirmation is required.
Card that was lost or stolen - The card issuer may block the card if the cardholder claims it is missing or stolen. This prevents unauthorized use of the cards until a replacement card is delivered.
Suspicious Activities Indicators - Any behavior or activity that is associated with the card and is suspect could result in an immediate block. Examples include several declined transactions, geographic anomalies, or unusual spending patterns.
If a card appears in a "blacklist", the holder could not make use of credit or their credit card until the issuer has checked the validity of the card or addressed any concerns regarding fraud or security. The cardholder must contact the issuer immediately to address the issue, verify the transactions and address any security issues.
How Do Cybersecurity Experts Detect And Monitor Cyber-Attacks Such As Stolen Credit Card Data?
Cybersecurity experts employ a variety of strategies, tools and techniques to recognize and track cyber-attacks, including stolen credit card information. Below are a few of the more common methods.
Information from various sources such as forums such as dark-web monitoring, forums, feeds for intelligence, and security alerts to stay up-to date on new threats and weaknesses.
Network Monitoring and Intrusion Detection
Software and tools that monitor the network traffic to identify suspicious activity, anomalies or other signs of unauthorized access.
Penetration and vulnerability tests-
Conducting regular checks to detect weaknesses in applications, systems, or networks. Penetration testing is a simulated attack that exposes weaknesses and reveals the security posture of an organisation.
Security Information and Event Management Security Information and Event Management
Implementing SIEM tools that combine and analyze log information from different sources (such as servers, firewalls, or applications) to detect and respond to security issues in real-time.
Behavioral analytics -
The application of behavioral analysis to detect any abnormal patterns, deviations or deviations from normal user behaviors within networks or systems that may signal a potential security risk.
Threat Hunting-
Looking for suspicious or threats activity within an organization’s network using logs, data and system information. This can help uncover dangers that aren't being detected using traditional security methods.
Endpoint Security Solutions
Protecting individual devices and systems from malicious activity through the use of endpoint security products including antivirus, antimalware, and endpoint detection and response (EDR) tools.
Data Security and encryption
Implementing encryption technology to protect sensitive data including credit card information at rest and in transit as well as at rest, to minimize the chance of data breach.
Incident Response and Forensics
To be able to respond quickly in the event of security breaches, incident response planning is essential. Investigating to find out the nature of impact, the cause and root of security incidents.
Cybersecurity experts combine these strategies and a deep understanding with compliance regulations and best-practices to recognize, limit and respond quickly to cyber-related threats. To ensure a strong defense against cyber attacks it's essential to keep up with continuous monitoring, intelligence and a proactive approach.
