One-third of all the Americans' information has been leaked by a background check company in the United States due to a disturbing data breach report. MC2 Data, which is one of the largest providers of background checks in the US, has left an enormous database unchecked online, putting millions of people's sensitive information at risk.

According to a Cybernews report from 23 September, this was first found out when MC2 Data left 2.2 TB of personal data open for anyone on the internet. This translates to over 106 million records about individual entities, which it claims may have affected the privacy of more than 100 million individuals. More than 2.3 million users' record details are also compromised; they had also asked for background checks, and their details were now open to the public.

Potential Effects of the Leaks

Comments by Aras Nazarovas, Cybernews security researcher: "These leaks are quite concerning, thinking of all the possible aftermaths which will not only result in extra problems always connected with identity theft, but may also involve numerous communities and organisations in battles-the cybercrime attackers commonly draw on background checks for such detailed personal information to prepare for attacks on individuals or groups.".

Background check services, intended to enhance security, have themselves not gone scot-free from cyber attacks and threats. The magnitude of the leakage can form a treasure trove of malicious users who can now access sensitive information more easily while still incurring less risk in perpetuating cyber attacks. Such leakage may underlie long-term trends in which personal data will be insecure in a society that increasingly digitalizes.

A Persisting Industry Problem

To the dismay of privacy advocates, this is not the first major breach involving a background check company. In August 2024, National Public Data, another giant in the background check sector, disclosed that it had suffered a breach exposing 2.7 billion public records. The compromised data included sensitive details such as names, social security numbers, email addresses, phone numbers, and birth dates.

It was reported that the leak at National Public Data started in December 2023, but the leaked data was published in April 2024. Cybersecurity specialists warn that such sensitive information being free for all to access increases the risk of more cyber attacks on people whose sensitive data have been leaked.

Consumer Watchdogs Raise the Alarm

In light of such repeated breaches, the consumer watchdog director for the U.S. Public Interest Research Group, Teresa Murray, said that this is indeed an extremely serious issue. Talking to ASIS International, Murray pointed out that due to its scale, what happened in the National Public Data breach makes it even more frightening compared to similar breaches. She said that people should view this as a "five-alarm wake-up call" to start taking their data security seriously.

Both those breaches are harsh reminders about the vulnerabilities that exist in the background check industry and the necessity of further security measures. Individuals are encouraged to monitor their personal information on a regular basis and take proactive steps about protecting them from identity theft and other forms of cybercrime.

What Needs to Be Done

Amid this swelling tide of data breaches, companies involved in handling sensitive information - such as firms conducting background checks - must be more attentive to their cybersecurity. Better data protection practices and more robust encryption and authentication systems can minimise this risk very well. In addition, individuals need to be vigilant as well. They must monitor each suspicious activity related to their personal information at regular intervals.

These breaches underscore the need for better regulations and also more oversight of operations that house large amounts of personal data. Unless further security is achieved, millions of Americans will remain vulnerable to danger from poor data protection.

Most recently, information fraud related to MC2 Data and National Public Data placed the identities of millions of Americans at risk of identity theft and other cybercrimes. Therefore, such cases occur frequently, and it is time for the business world and consumers to take data security seriously to prevent sensitive information from falling into the wrong hands.
