The Nigerian Communications Commission’s Computer Security Incident Response Team (NCC-CSIRT) has rolled out advisories against cyber threat actors, who continue to devise means of compromising their targets.
Reuben Muoka, Director, Public Affairs at NCC said, in a statement, the advisory is in line with the NCC-CSIRT’s mandate.
The latest of such advisories urged users to be mindful of attackers using Microsoft OneNote attachments in phishing emails.
Such attachments infect victims with remote access malware, which may allow hackers to remotely access vital information on victims’ devices.
The NCC-CSIRT team, therefore, advised users not open files from people they do not know.
It asked people not to click ‘OK’ but should immediately exit the application.
That is, if they receive warning that opening an attachment or link can damage their computer or files.
It also advised users to promptly share an unknown email, they believe to be genuine, with security or Windows administrator.
They should do this to seek assistance in determining whether the file is secure.
NCC-CSIRT recently advised people not to open attachments in suspicious emails.
It asked them to only buy or download applications from official websites.
The advice was in response to the discovery of phishing malware that can gain unauthorised access to sensitive user data and download further malware.
The team reported that cybersecurity analysts at ASEC (South Korea’s cybersecurity emergency response centre), discovered NetSupport RAT malware being distributed by threat actors from a phishing website.
