Threat Analysis: Helpdesk Hijackers and Critical WordPress Exploits, What UK SMBs Need to Know
Hello, Mauven here. Today, we examine two significant cyber threats impacting UK SMBs: Helpdesk Hijackers exploiting Teams and a critical exploitation found in WordPress Core.
Helpdesk Hijackers: Microsoft Teams Vishing Attacks
Since early 2026, a cunning group has been executing vishing attacks via Microsoft Teams. This faction acts as an initial access broker, targeting victims by masquerading as IT helpdesk staff. When unsuspecting users comply and initiate a Quick Assist session, the attackers deploy a backdoor known as GoGRPC.
Why should UK SMBs care? Because these intrusions don’t just inconvenience; they pave the way for ransomware attacks. If you rely on Teams for collaboration, reinforce staff awareness and verify all helpdesk requests.
WordPress Vulnerabilities: wp2shell Threat
The discovery of two vulnerabilities in WordPress Core, affecting versions from 6.9.0 to 7.0.1, is cause for concern. These flaws can allow unauthenticated remote code execution and full site takeover. Exploited together, attackers gain administrator access and can deploy webshells. The NCSC has emphasised that patching should be immediate.
Implications for UK SMBs
This isn’t mere scaremongering. An exploited WordPress site can disrupt operations, tarnish reputations, and lead to losses both financial and administrative. These vulnerabilities are actively targeted, with UK websites consistently at risk.
Ensure that your WordPress installations are promptly updated and that staff handling sensitive applications receive proper training.
