Darktrace Reports Information Technology and Communications Sector Most Targeted by Cyberattackers in 2021 – DARKReading
CAMBRIDGE, England, Dec. 13, 2021 /PRNewswire/ — Darktrace, a global leader in cyber security AI, today reported that the information technology (IT) and communications sector was the most targeted industry globally in 2021, as uncovered by Darktrace’s security researchers.
Darktrace’s data is developed by ‘early indicator analysis’ that looks at the breadcrumbs of potential cyber-attacks at several stages before they are attributed to any particular actor and before they escalate into a full-blown crisis. Darktrace’s findings show that its artificial intelligence autonomously interrupted an average of 150,000 threats per week against the sector in 2021.
The IT and communications sector includes telecommunications providers, software developers, and managed security service providers, amongst others. Darktrace also defends several backup vendors and has observed a growing trend of hackers targeting backup servers in an attempt to deliberately disable or corrupt backup files by deleting a single index file that would render all backups inaccessible. Attackers could then launch ransomware attacks against the clients of the backup vendor, preventing recovery and forcing payment.
In 2020, the most attacked industry across Darktrace’s global customer base was the financial and insurance sector, showing that cyber-criminals have shifted their focus over the last 12 months.
“Over the last 12 months, it is clear that attackers are relentlessly trying to access the networks of trusted suppliers in the IT and communications sector. Quite simply, it is a better return on investment than, for example, going after one company in the financial services sector. SolarWinds and Kaseya are just two well-known and recent examples of this. Sadly, there is likely to be more in the near term,” commented Justin Fier, Darktrace Director for Cyber Intelligence and Analysis.
The findings of this research mark one year since the compromise of U.S. software company SolarWinds rattled the security industry. This landmark supply-chain attack made thousands of organizations vulnerable to infiltration by inserting malicious code into the Orion system. Over the last 12 months, there has been a continued spate of attacks against the IT and communications sector, including the high-profile attacks on Kaseya and Gitlab.
Threat actors often use software and developer platforms as entry points into other high-value targets, including governments and authorities, large corporations, and critical infrastructure. Darktrace found that the most common attempted break-in method was through email, with organizations in the sector receiving an average of 600 unique phishing campaigns a month in 2021. Contrary to popular belief, the emails sent to these organizations did not contain a malicious payload hidden in a link or attachment. Instead, cyber-criminals used subtle and sophisticated techniques sending ‘clean emails’ containing only text attempting to coax recipients into replying and revealing sensitive information. This method is effective because, by compromising these email accounts, hackers can then exploit the trusted relationship between the software supplier and the intended targets.
These methods easily bypass legacy security tools that rely on checking links and attachments against blocklists and signatures. AI can stop these emails from reaching employees’ inboxes by identifying the full range of anomalies, including even the most subtle indicators.
“The reality is that attackers are patient and creative. They will usually go right through the front door …….
