Russian and Iranian Spear Phishing Campaigns are Running Rampant in the UK
The UK’s National Cyber Security Centre (NCSC) has described two separate spear phishing campaigns launched by Russia’s SEABORGIUM threat actor and Iran’s TA453 (also known as Charming Kitten). The NCSC says both threat actors have targeted entities in the UK, including “academia, defence, governmental organisations, NGOs, think-tanks, as well as politicians, journalists, and activists.”
The threat actors first conduct reconnaissance on their targets by researching social media and other open-source information. After this, they’ll make contact under the guise of a journalist, colleague, or someone else the victim would be likely to respond to.
“Having taken the time to research their targets’ interests and contacts to create a believable approach, SEABORGIUM and TA453 now start to build trust,” the report says. “They often begin by establishing benign contact on a topic they hope will engage their targets. There is often some correspondence between attacker and target, sometimes over an extended period, as the attacker builds rapport.”
The threat actors then send the victim a link disguised as something related to their previous conversations.
“Once trust is established, the attacker uses typical phishing tradecraft and shares a link, apparently to a document or website of interest,” the NCSC says. “This leads the target to an actor-controlled server, prompting the target to enter account credentials. The malicious link may be a URL in an email message, or the actor may embed a link in a document on OneDrive, GoogleDrive, or other file-sharing platforms.
TA453 has even shared malicious links disguised as Zoom meeting URLs, and in one case, even set up a Zoom call with the target to share the malicious URL in the chat bar during the call. Industry partners have also reported the use of multi-persona impersonation (use of two or more actor-controlled personas on a spear-phishing thread) to add the appearance of legitimacy.”
