Phishing emerged as the range one danger vector in 2021, but circumstances of vulnerability exploitation surged 33% 12 months-on-12 months many thanks to the affect of Log4Shell, according to IBM.
The X-Force Risk Intelligence Index 2022 was compiled from billions of datapoints, like network and endpoint detection gadgets, incident response engagements and area name tracking.
It discovered that phishing overtook vulnerability exploitation as the leading pathway for compromise globally previous yr, accounting for 41% of initial accessibility tries, up from 33% in 2020.
Curiously, simply click rates for the regular specific phishing campaign enhanced all-around a few-fold, from 18% to 53%, when phone phishing (vishing) was also employed by threat actors.

IBM highlighted enterprise email compromise (BEC) and ransomware actors as specially prolific end users of phishing for the duration of 2021.
Regardless of dropping into 2nd position, vulnerability exploitation remains a important threat to businesses. The number of incidents working with this as an an infection vector surged by a third year-on-calendar year in 2021.
“X-Power noticed actors leveraging many acknowledged vulnerabilities, these as CVE-2021-35464 (a Java deserialization vulnerability) and CVE-2019-19781 (a Citrix path traversal flaw), to acquire initial entry to networks of desire,” the report observed.
“In addition, we observed risk actors leverage zero-day vulnerabilities in key attacks like the Kaseya ransomware attack and Microsoft Exchange Server incidents to entry sufferer networks and products.”
Nevertheless, it was Log4j vulnerability CVE-2021-44228 (aka Log4Shell) which seems to have driven the vector’s increase in recognition in 2021. In spite of only being disclosed in December, it was the 2nd-most exploited bug in excess of the full calendar year, the report claimed.
This echoes findings from Fortinet, which disclosed this 7 days that Log4Shell was its most commonplace detection of the complete next half of 2021.
“In considerably less than a month, the Log4j RCE managed almost 50 times the action of 2021’s other darling, ProxyLogon, calculated by peak 10-working day normal quantity,” it stated.
