Following up on the recent news of Russia linked threat actors targeting Signal, WhatsApp and Telegram Fredrik Almroth, co-founder and Security Researcher at appsec security firm Detectify serves up some perspective on how messaging apps and personal devices are becoming an increasingly important part of the real attack surface.
“The broader lesson is that organizations should stop treating secure messaging as a silver bullet. Strong encryption matters, but it does not protect you if the endpoint is compromised or the account itself is hijacked. What makes this trend so concerning is that it blurs the line between consumer technology and resilience infrastructure. Messaging apps, smartphones, and linked devices are now woven into how governments, companies, and critical sectors actually function – often adopted at a velocity that traditional security struggles to match.
Modern defense is no longer just about protecting official systems, but about protecting the communications reality people actually operate in. The attack point is often not the ‘secure bunker,’ but the phone in someone’s pocket. From an attacker’s perspective, these channels are attractive precisely because they are trusted, ubiquitous, and often far less visible to defenders than formal enterprise systems. If hostile actors can reach decision-makers, staff, or even suppliers through trusted channels, they can bypass a surprising amount of traditional security.
Often, they do not need to break encryption at all. They just need to compromise the device, hijack the account, abuse a linked-device workflow, or trick the user at the right moment. This is why the communications layer around sensitive institutions is now part of the real attack surface.
In practice, that means paying far more attention to mobile-device hygiene for executives and other high-risk personnel. You don’t just need to secure the network, but also improve the communications habits around your it. Smart attackers will always go for the points of least resistance.You can spend millions hardening formal systems, but if your most sensitive conversations are happening on poorly governed devices and trusted consumer apps, that’s where they’ll go.”
