Cybersecurity risks threatens the hybrid workplace

November 2, 2021

HP Inc. released its latest HP Wolf Security report: Out of Sight & Out of Mind, a comprehensive global study highlighting how the rise of hybrid work is changing user behaviour and creating new cybersecurity challenges for IT departments.

The research shows that a growing number of users are buying and connecting unsanctioned devices outside of IT’s purview. It also highlights that threat levels are rising, with attackers increasingly successful at bypassing defences and tricking users into initiating attacks through phishing. All of this is making IT support more complex, time-consuming, and costly than ever.

The report combines data from a global YouGov online survey of 8,443 office workers who shifted to Working from Home (WFH) during the pandemic, and a global survey of 1,100 IT decision makers conducted by Toluna. Key findings include:

• New Shadow IT buying and installing endpoints with security out of mind: ‘Shadow IT’ typically refers to non-IT departments deploying software beyond the purview of IT. This shadow is now spreading, with individuals procuring and connecting devices without being checked by IT. 45% of office workers surveyed purchased IT equipment (such as printers and PCs) to support home working in the past year. However, 68% said security wasn’t a major consideration in their purchasing decision, while 43% didn’t have their new laptop or PC checked or installed by IT, and 50% said the same of their new printer.
• Phishing becoming increasingly successful: 74% of IT teams have seen a rise in the number of employees opening malicious phishing links or attachments on emails in the last 12-months. 40% of office workers surveyed aged 18-to-24 have clicked on a malicious email with almost half (49%) saying they have done so more often since working from home. Of office workers that clicked or nearly clicked a link, 70% didn’t report it to IT – 24% didn’t think it was important, 20% cited the “hassle factor”, while 12% had a fear of reprisal or being punished.
• Increase in devices being compromised fuels growth in rebuild rates: 79% of IT teams report rebuild rates increased during the pandemic. Rebuild rates directly correlate to the number of endpoints that require wiping and reimaging because they have been compromised, which implies more attackers are successfully breaching outer defenses. The real figure could be higher still: 80% of IT teams worry that employee devices might be compromised and they don’t know about it.

“People often don’t know if they have clicked on something malicious, so the real numbers are likely much higher,” commented Ian Pratt, Global Head of Security for Personal Systems, HP Inc. “Threat actors don’t always announce themselves, as playing the ‘long game’ to move laterally and infiltrate higher-value infrastructure has proven to be more lucrative. For example, by using cloud backups to exfiltrate sensitive data in bulk, encrypting data on servers, then demanding a multi-million-dollar ransom.”

Pratt continued: “It shouldn’t be this easy for an attacker to get a foothold – clicking on an email attachment should not come with that level of risk. By isolating and containing the threat you can mitigate any harmful impact, preventing persistence and lateral movement.”

The increasing unmanageability of IT security support
With threats rising, it is becoming more difficult for IT teams to deliver security support. 77% of IT teams said the time it takes to triage a threat has increased in the past year, while an estimated 62% of alerts relating to the endpoint are false positives, leading to wasted time. With IT teams tied up dealing with alerts, it’s becoming harder for them to onboard employees and identify threats:

• 65% of IT teams said that patching endpoint devices is more time-consuming and difficult due to the mass shift to home working, while 64% said the same of provisioning and onboarding new starters with secure devices.
• As a result, IT teams estimate the cost of IT support in relation to security has risen by 52% in the last 12-months.
• 83% of IT teams said the pandemic has put even more strain on IT support because of home worker security problems, while 77% of IT teams say homeworking is making their job much harder and that they fear teams will burnout and consider quitting.

“As IT continues to grow in complexity, security support is becoming unmanageable,” Pratt concluded. “For hybrid working to be a success, IT security teams need to be freed from spending hours provisioning and fielding user access requests so they can focus on tasks that add value. We need a new security architecture that not only protects against known and unknown threats, but that helps to reduce the burden to liberate cybersecurity teams and users alike. By applying the principles of Zero Trust, organisations can design resilient defences to keep the business safe and recover quickly in the event of a compromise.”
