Manufacturing sector topped the list of industries attacked in the region with 48% of cases. It was followed by finance and insurance with 18% of cases.
Spear phishing by attachment was found to be the top infection vector at 40%, with deployment of backdoors, which allow remote access to systems, emerged as the top action by attackers accounting for 31% of cases, followed by ransomware at 13%, the X-Force Threat Intelligence Index found.
Majority of these backdoor attempts observed globally were failed ransomware attempts, where defenders were able to detect the backdoor before ransomware was deployed, the report shared.

Extortion was witnessed as the most common impact from cyberattacks, which was primarily achieved through ransomware or business email compromise with thread hijacking witnessing significant rise.
These attacks were found to unevenly target businesses, with manufacturing being the most extorted industry in 2022. Cybercriminals increasingly targeted manufacturing due to its low tolerance for down time.
Attackers using compromised email accounts to reply within ongoing conversations posing as the original participant witnessed a monthly increase of 100% in 2022 when compared to 2021 data, the report shared.
And though the use of legacy exploits declined by 10% from 2018-2022, findings in the report indicate that legacy exploits enabled older malware infections like WannaCry and Conficker continue to be deployed by cybercriminals. Legacy exploit WannaCry ransomware reported an 800% increase in traffic within MSS telemetry data since April 2022, the report shared.
“Businesses in Asia-Pacific including India will continue to face growing numbers and sophistication of cyber threats as bad actors take advantage of economic and geopolitical disruptions. Hence, it is imperative that business leaders take immediate action to prepare and secure against these malicious threats”, said Viswanath Ramaswamy, Vice President, Technology, IBM India & South Asia.
The report is based on data collected globally in 2022 by IBM.
