Recent research paints a concerning picture of the email security landscape, revealing a surge in malicious email activity coupled with evolving attack strategies. This surge is marked by a notable increase in the use of Remote Access Trojans (RATs), open redirects, and malicious microsoft Office documents, along with a significant shift in data exfiltration tactics.
Alarmingly, at least one malicious email manages to bypass secure email gateways (SEGs), such as Microsoft and Proofpoint, every 45 seconds, a worrying rise from last year’s rate of one every 57 seconds. This finding, highlighted in Cofense Intelligence’s third-quarter Trends Report, underscores the growing sophistication and persistence of cyberattacks.
The Growing Threat of RATs
One of the most significant trends is the sharp increase in the use of Remote Access Trojans (RATs). These malicious tools empower attackers to gain unauthorized access to a victim’s system, frequently enough leading to data theft or further exploitation.
Remcos RAT, a widely used tool among cybercriminals, is a key contributor to this rise. This insidious software allows remote control of infected systems, enabling attackers to exfiltrate data, deploy additional malware, and establish persistent access to compromised networks.
Open Redirects and Malicious Documents: A One-Two Punch
Cybercriminals are also increasingly exploiting open redirects in phishing campaigns.
This tactic, which sees a 627% increase in usage, leverages the functionality of legitimate websites to redirect users to malicious URLs, effectively masking the threat behind well-known and trusted domains. Popular platforms like TikTok and Google AMP are frequently enough exploited in these attacks, taking advantage of their global reach and frequent use by unsuspecting individuals.
Another notable trend is the surge in malicious Microsoft Office documents,particularly those in .docx format, with usage rising by nearly 600%. These documents often contain phishing links or QR codes that lead victims to harmful websites.
microsoft Office documents remain a popular attack vector due to their widespread use in business environments, making them ideal for targeting organizations through spear-phishing campaigns.
Shifting Tactics: The Rise of .ru and.su Domains
Cybercriminals are also adapting their data exfiltration tactics. There is a significant shift toward the use of .ru and .su top-level domains (TLDs). Domains using the .ru (Russia) and .su (Soviet Union) extensions have seen usage spikes of more than fourfold and twelvefold, respectively. This shift indicates a purposeful strategy to evade detection and make it harder for victims and security teams to track data theft activities.
