cyberattacks

Cybercriminals spent more time in their victims’ systems in 2021 compared with 2020, the latest report by cybersecurity company, Sophos, has established. According to Sophos, the dwelling time of attackers increased by 36% last year, with a median intruder dwell time of 15 days in 2021 versus 11 days in 2020.

The company, in its ‘Active Adversary Playbook 2022‘  released today, says the longer dwell times mean that it is now becoming hard for in-house IT security staff of organizations to proactively hunt for, investigate, and respond to suspicious alerts and potential threats.

Sophos also discovered that intruder dwell time was longer in smaller organizations’ environments, as attackers lingered for approximately 51 days in organizations with up to 250 employees, while they typically spent 20 days in organizations with 3,000 to 5,000 employees.

What they are saying 

Sophos, in the report, warned that every organization is a target of cyber-attacks which range from phishing and financial fraud to botnet builders, malware delivery platforms, crypto miners, IABs, data theft, corporate espionage, ransomware, and more. It noted that if there is a vulnerable entry point into a network, the chances are that attackers are looking for it and will eventually find and exploit it.
