Throughout 2020, the COVID-19 pandemic created something of a new playground for hackers. In response, many institutions fortified cybersecurity systems and fast-tracked digital transformation initiatives. But what does the landscape for cybersecurity and the evolution of threats look like in 2021? We don’t have a crystal ball, but here are five cybersecurity trends to watch out for in the new year.

Social engineering is a term that refers to efforts by hackers and cybercriminals to use people — rather than technology — to gain access to sensitive systems and information. It’s a problem that information security experts have been wrestling with for years and one that, in the midst of COVID-19, has become both more prevalent and more challenging.

One type of social engineering attack is the personalized-message, which often ends up in the hands of the CEO or another executive who would have access to sensitive files and information. Until recently, email was the dominant medium by a wide margin. However, recently, attackers have started to move to social media and text messages. What can you do about it?

Purdue University is offering new cybersecurity short courses in social engineering and digital forensics as part of a growing suite of offerings through the Purdue Polytechnic Institute’s Cyber Education Network Training Resources (CENTR).

Two men will appear in federal court to face charges that they were involved in the unauthorized takeover of social media and other personal online accounts belonging to professional and semi-professional athletes, U.S. Attorney Craig Carpenito announced.

Recently, two teens and a young adult infiltrated one of Silicon Valley’s biggest companies in a high-profile hack – and the biggest ever for Twitter. Authorities say the 17-year-old “mastermind” used social engineering tactics to convince a Twitter employee that he also worked in the IT department and gained access to Twitter’s Customer Service Portal. The 130-account takeover proved unique, as it was fundamentally a dramatic manipulation of trust and could have had far more world-changing consequences if the attackers had the aspirations of say, a dangerous fringe group versus that of a teenager. There are a few takeaways to learn here, especially when it comes to considering redefining what we classify as “critical infrastructure” and what must be protected at all costs.

Organizations need to enhance current technical security controls to mitigate against the threat of deepfakes to the business. Training and awareness will also need revamping with special attention paid to this highly believable threat.

As digital security through online portals continually improves and people become more wary of phishing emails, hackers have turned to old fashioned telephone calls to elicit key pieces of personal information they can use for profit. It takes little technical skill—just the ability to sound convincing to vulnerable people over the phone.
