Russian Hackers Target Kremlin Critics Worldwide Exposing Aggressive Phishing Campaign
In a concerning development, hackers connected to Russian intelligence are actively targeting Kremlin critics around the world through sophisticated phishing campaigns. This alarming cyber-espionage operation was recently exposed by the digital rights groups Citizen Lab and Access Now, and it highlights the growing threat of cyberattacks as the 2024 U.S. presidential election approaches.
These phishing attacks, which began in 2022, have compromised a wide range of individuals and organizations, including Russian opposition figures in exile, former U.S. policy officials, academics, staff of U.S. and EU nonprofit organizations, and various media outlets. The hackers’ reach even extends to individuals still residing in Russia, placing them in significant danger. The primary objective of these attacks appears to be infiltrating the victims' extensive networks of contacts, thereby gaining access to sensitive information.

Sophisticated Phishing Tactics via Impersonation and Deception
What makes this phishing campaign particularly dangerous is its method of impersonating individuals known to the victims, thereby increasing the likelihood of the email being opened and trusted. This deceptive tactic sets this operation apart from typical phishing attempts and has led to successful breaches.
Citizen Lab has identified two Russian hacking groups behind these attacks. The first, Cold River, has been linked to Russia's Federal Security Service (FSB) by Western intelligence. The second group, Coldwastrel, is a newer entity that also seems to be aligned with Russian intelligence efforts.
The Role of Citizen Lab and Access Now in Uncovering the Attack
Despite repeated denials from Russia regarding involvement in such activities, including those linked to Cold River, the evidence presented by Citizen Lab paints a different picture. Notably, one of the targets was a former U.S. ambassador to Ukraine, who was approached through a credible phishing attempt that impersonated another former ambassador known to him.
The phishing emails typically included a PDF attachment that, once clicked, redirected the recipient to a fake Gmail or ProtonMail login page. Victims who entered their credentials on these spoofed sites unwittingly granted hackers access to their email accounts and contacts. Unfortunately, several individuals fell prey to this tactic.
How These Phishing Attacks Unfolded
Dmitry Zair-Bek, leader of the Russian rights group First Department, emphasized the effectiveness of this straightforward yet potent attack. The nature of the emails, appearing to come from colleagues, made them particularly difficult to spot as fraudulent. According to Zair-Bek, the number of targeted individuals is in the double digits, with most incidents occurring this year.
Citizen Lab stressed the serious implications of these attacks, particularly for those with connections to high-risk communities in Russia. For some, a successful compromise could lead to severe consequences, including imprisonment.
Cold River has rapidly become one of the most prolific Russian hacking groups since it first appeared on intelligence radars in 2016. Following Russia's invasion of Ukraine, the group escalated its activities, leading to sanctions being imposed on some of its members by U.S. and British authorities in December.
