Security News > 2023 > September > Old vulnerabilities are still a big problem
A recently flagged phishing campaign aimed at delivering the Agent Tesla RAT to unsuspecting users takes advantage of old vulnerabilities in Microsoft Office that allow remote code execution.
"Despite fixes for CVE-2017-11882/CVE-2018-0802 being released by Microsoft in November, 2017 and January, 2018, this vulnerability remains popular amongst threat actors, suggesting there are still unpatched devices in the wild, even after over five years," says Fortinet researcher Xiaopeng Zhang.
"We are observing and mitigating 3000 attacks per day, at the IPS level. The number of observed vulnerable devices is around 1300 per day."
On Monday, Qualys published its list of top 20 vulnerabilities exploited by malware, threat actors, and ransomware gangs.
Some are very old and others newer, but the newest date back to two years ago.
Attackers know and count on the fact that many systems remain unpatched for years and years.
