Cybersecurity experts recently uncovered a large-scale spear-phishing campaign by a threat actor called Midnight Blizzard. This campaign uses Remote Desktop Protocol (RDP) files to trick victims and gain access to sensitive systems.
Spear-phishing is a targeted type of phishing. Instead of sending generic emails, attackers personalize messages to trick specific individuals. These messages often appear to come from trusted sources.
In the Midnight Blizzard campaign, attackers send emails containing malicious RDP files. These files look legitimate but are designed to trick users into granting remote access to attackers.
Midnight Blizzard’s approach is sophisticated. Using RDP files is unusual in phishing campaigns, making this tactic harder to detect. The targeted nature of spear-phishing also increases its success rate. Victims are more likely to trust personalized emails.
Here are simple steps to stay safe:
