— Defending Indonesia's digital backbone and subscriber data
Telecommunications
Indonesia's major telcos serve over 370 million mobile connections. They form the backbone of the digital economy. They are also high-value targets. SIM swap fraud, signaling attacks, DDoS campaigns, and subscriber data theft threaten operations daily. The 5G rollout is widening the attack surface. Alpha Code provides cybersecurity built for telcos. We cover network infrastructure, subscriber data protection, and Kominfo compliance.

SIGNALLING RISK
SS7 vulnerabilities are actively exploited in Indonesia
SS7 signalling networks and Diameter protocol implementations in Indonesian 4G/5G infrastructure carry known vulnerabilities. Attackers use them for subscriber tracking, call interception, and SMS redirection. SS7 attacks on SMS-delivered OTPs appear in documented financial fraud cases against Indonesian banking customers.
AUTHENTICATION ROLE
Telco security underpins the national authentication chain
Indonesian banks, e-commerce platforms, and government services often rely on SMS OTP as a second factor. The telco that delivers that message becomes part of their authentication chain. A failure at the telco layer, through SS7 exploitation or SIM-swap fraud, compromises every service that trusts SMS for authentication.
BREACH PATTERNS
Unpatched systems and excess data retention drive incidents
Major Indonesian telco data breaches share a clear pattern. They involve unpatched internet-facing systems and data kept beyond business need. They also involve weak access controls on customer databases. In response, Kominfo now requires telcos to run annual security assessments and keep incident response plans.
Understanding the risks
Key cybersecurity threats facing organizations in this sector.
01
SIM Swap Fraud & Subscriber Identity Attacks
SIM swap fraud lets attackers hijack mobile numbers. They use this for OTP interception, banking fraud, and identity theft. Indonesian telcos face growing pressure from regulators and banks to set up stronger prevention controls.
02
Network Infrastructure & SS7/Diameter Attacks
Legacy SS7 and newer Diameter interfaces sit in 4G/5G networks. They expose telcos to location tracking, call interception, and subscriber data theft. These protocol-level attacks can compromise an entire subscriber base.
03
DDoS Attacks Targeting Network Availability
Telcos face massive DDoS attacks. These hit DNS infrastructure, IP transit networks, and customer portals. Volumetric attacks over hundreds of Gbps can degrade service for millions of subscribers and enterprise customers.
04
5G & Edge Computing Security Risks
5G deployments across Indonesia add new attack surfaces. These come from network slicing, multi-access edge computing, and virtualized network functions. Cloud-native 5G core architectures need different security approaches than legacy network elements.
Stay compliant, stay protected
Key regulatory frameworks and standards your organization needs to meet.
PP 71/2019 & PR 82/2022
Government Regulation on Electronic System Operation
Telecom operators must run information security management systems. They must conduct regular security audits and set up incident response. They must register electronic systems with Kominfo. The rule adds data localization for strategic electronic systems.
Kominfo Telecom Regulations
Ministry of Communication & IT Telecommunications Security Standards
Kominfo sets telecom-specific security rules. These include lawful interception and subscriber data protection standards. They also cover spam and fraud prevention. They set network resilience rules for critical telecommunications infrastructure.
UU 27/2022 (UU PDP)
Undang-Undang Pelindungan Data Pribadi
Telecommunications operators that process subscriber personal data must follow UU PDP rules. These cover purpose limitation, data minimization, and subscriber consent management. They require 72-hour breach notification for incidents that affect customer data.

Common questions
How does Alpha Code address SIM swap fraud for telcos?
We set up multi-layered SIM swap prevention. This includes real-time fraud scoring at point of sale and behavioral analytics for suspicious SIM change patterns. We integrate banking sector fraud feeds and add stronger identity verification workflows. Our approach has cut successful SIM swap attacks by over 90% for Indonesian operators.
What 5G security risks should Indonesian telcos prioritize?
Priority areas are clear. Secure the cloud-native 5G core against container and API attacks. Set up network slice isolation to prevent cross-tenant compromise. Protect multi-access edge computing nodes. Lock down roaming security for 5G standalone networks. We advise a 5G security architecture assessment before commercial launch.
Can you help with Kominfo regulatory compliance for telcos?
Yes. We support compliance with all Kominfo telecommunications security rules. This covers ISMS setup, security audit prep, and incident response capability. It also covers data localization assessment. Our team has direct experience with Kominfo audit processes.
How do you protect subscriber data at telco scale?
We set up data protection programs across subscriber databases, CDR repositories, billing systems, and CRM platforms. This includes data classification and encryption at rest and in transit. It also includes privileged access management. We monitor for unauthorized data access patterns.
What is the telco SOC different from a standard enterprise SOC?
A telecom SOC must process far more data than a standard enterprise SOC. It must correlate events across network infrastructure and IT systems. It must detect telecom-specific threats like signaling attacks. It must see both subscriber-facing and backend operations. We build purpose-fit telecom SOCs with specialized data pipelines, telco threat intelligence, and operator-grade scale.
