The supplier of file transfer and collaboration tools released four fixes in January to patch weaknesses in its File Transfer Appliance service. However, ransomware gangs exploited the vulnerabilities before every user could install the fix. As a result, The U.S. Department of Health and Human Services and the University of California, among other clients, were affected.

6. Mimecast

A document produced by Mimecast that was used to verify cloud-based email marketing services for Microsoft Office365 Exchange was hacked at the beginning of the year. While Microsoft notified users of the intrusion, around 10% of its clients used the exposed connection before installing a fix.

5. LinkedIn

In June, a government investigation started after it was uncovered that 700 million LinkedIn members had their data scraped and shared online. It was soon available for purchase on RaidForums. The social media site claimed no private LinkedIn user data was revealed. This came on the heels of an April incident in which 500 million users were exposed. However, LinkedIn reported the stolen information during that event was already publicly available.

Whether you’re a small independent insurance agency or a massive health care conglomerate, hackers see the same thing; another rube waiting to be exploited.

In fact, more than half of small businesses in the U.S. have said they’ve been a victim of a cyberattack, while one-third have been exposed at least three times, according to the Identity Theft Resource Center (ITRC).

During the most recently closed quarter, data breaches showed a decline, ITRC reported. While incidents fell off in Q3, ITRC cautioned that 2021 is still likely to set a record in terms of the number of incidents.

“The resources stolen by cybercriminals are the same resources needed to sustain or grow a business to keep families safe, healthy and financially secure,” Eva Velasquez, president and CEO of the ITRC, said in a release. “It is critical we share these eye-opening findings so everyone can better understand the impacts of identity crimes, particularly on people just trying to support their families and the families of their employees.”

The above slideshow highlights the biggest data breaches, to date, in 2021 and showcases the fact that no industry is immune from hackers’ reach, according to Analytics Insight.
