Russian Hackers Widen Access Routes Arabian Post

A major concern is the use of valid credentials. Attackers are no longer relying only on malware-laden attachments or exposed software flaws. Stolen usernames, passwords, session tokens and multifactor authentication workarounds allow intruders to sign in as legitimate users, reduce the chance of triggering alarms and move laterally once inside a network. Access brokers and criminal marketplaces have lowered the cost of obtaining these credentials, giving state-linked operators faster routes into high-value systems.

VPNs and remote desktop services remain attractive because many organisations depend on them for hybrid work, outsourced IT support and emergency administration. Weak passwords, reused credentials, missing multifactor authentication, legacy gateways and poorly monitored login patterns create opportunities for attackers to enter without exploiting a zero-day vulnerability. Once access is established, intruders often map internal systems, harvest further credentials and search mailboxes, file shares and cloud storage for sensitive material.

Supply chain compromise has become a parallel route. Russian-linked actors have targeted vendors, managed service providers, logistics partners and smaller technology firms that sit close to more heavily defended organisations. A supplier with weaker controls can provide a path into customers, transport schedules, operational data or defence-related communications. This has raised concern among companies that may not consider themselves direct geopolitical targets but handle data or services connected to governments, energy networks, military support chains or critical infrastructure.

Campaigns connected to the war in Ukraine show how cyber operations are being used to support wider military and intelligence objectives. Logistics companies, rail operators, border-adjacent infrastructure, camera systems and technology suppliers have been targeted to gain visibility into the movement of aid and equipment. Compromised internet-connected cameras and poorly secured network devices have offered surveillance value without requiring attackers to breach core enterprise systems first.

Social engineering has also grown more sophisticated. Phishing emails now sit alongside fake help-desk interactions, spoofed professional portals, malicious remote desktop files, impersonation of trusted contacts and lures tailored to specific sectors. Defence employees, journalists, public officials, drone specialists and contractors have faced highly personalised attempts designed to exploit professional routines rather than technical weakness alone.

The tactics create difficult choices for defenders. Blocking every remote login or third-party connection is impractical, yet allowing broad access without strict controls gives attackers room to operate. Organisations are being pushed towards tighter identity management, stronger multifactor authentication, rapid removal of dormant accounts, conditional access policies, network segmentation and more aggressive monitoring of remote sessions.

Edge devices are a particular weakness. Routers, firewalls, VPN concentrators, remote access gateways and network management appliances often sit outside normal endpoint protection systems. Many run outdated firmware or have limited logging, making them valuable footholds for stealthy activity. Compromised devices can be used to capture traffic, relay commands, hide infrastructure and maintain persistence even after internal machines are cleaned.

The commercial impact is spreading beyond defence and government. Energy companies, transport firms, manufacturers, media groups and healthcare providers face heightened risk because their networks contain operational data, personal information and links to broader supply chains. Smaller firms are exposed because they may lack dedicated security teams, yet still hold credentials or access rights valuable to attackers.
