2021: Looking back on the year in malware and cyber attacks, from Solar Winds to Log4j
Summary: Cisco Talos looked back on 2021 as a year of one major incident after another, from the SolarWinds campaign a year earlier to the Log4j threat it said could last for years, alongside oil pipelines going offline, state-sponsored actors raising the stakes, and the Twitch platform being leaked in full. Talos reported that phishing remained the leading initial access technique, ransomware and pre-ransomware cases rose as a percentage, and finance and public administration tied as the top-targeted industries.
What you should know: Talos expects big game hunting and ransomware to keep rising into 2022, with phishing still the leading way attackers get in - and finance and public administration tied as the most-targeted industries.
