SIM Swap Attack: Your Phone Number Was Hijacked. Act Fast to Limit the Damage.
SIM swap attacks let criminals take over your phone number, bypass two-factor authentication, and drain bank accounts, cryptocurrency wallets, and email in minutes. The FBI's IC3 logged 982 SIM swap complaints with $26 million in losses. Speed is everything.
Key Takeaways
- Contact your mobile carrier immediately to report the swap and regain your number.
- Change passwords on all accounts that use SMS-based two-factor authentication.
- Switch to app-based or hardware-based authentication on every account that supports it.
- Check bank and cryptocurrency accounts for unauthorized transactions. Time matters.
- File a police report and an FBI IC3 complaint at ic3.gov to create an official record.

Call Your Carrier NOW
Report the unauthorized SIM swap and demand an immediate freeze on your account. Visit a physical store with government-issued photo ID if possible. Ask them to reverse the port, add a SIM lock, and set a unique account PIN. T-Mobile, AT&T, and Verizon all have fraud departments that can expedite this process.
Change Passwords from a Secure Device
From a computer or tablet you trust, change passwords on email first, then banking, cryptocurrency exchanges, and social media. Your email account is the master key. If attackers control it, they can reset every other password. Use a password manager to generate unique credentials for each account.
Remove SMS-Based 2FA Everywhere
SMS two-factor authentication is exactly what the attacker exploited. Replace it with app-based authenticators (Google Authenticator, Authy, Microsoft Authenticator) or hardware security keys (YubiKey, Titan). Prioritize email, banking, and crypto accounts. This single step eliminates the primary attack vector.
Audit All Financial Accounts
Check bank accounts, credit cards, cryptocurrency wallets, and payment apps (Venmo, Cash App, Zelle) for unauthorized transactions. Contact your bank's fraud department immediately if you find suspicious activity. The average SIM swap victim loses over $26,000, and the window to reverse transactions is narrow.
File Reports with Law Enforcement
File a complaint with the FBI's Internet Crime Complaint Center at ic3.gov. File a local police report. Submit an identity theft report with the FTC at identitytheft.gov. These reports create an official paper trail needed for bank disputes, insurance claims, and potential prosecution.
Petronella Technology Group Recovery vs. Doing It Yourself
You can handle basic steps on your own. But SIM swap attacks often involve multiple compromised accounts, leaked credentials on dark web markets, and persistence mechanisms most victims never find. Here is what professional recovery covers that self-recovery typically misses.
| Capability | Petronella Technology Group Recovery | Self-Recovery |
|---|---|---|
| Carrier escalation and expedited number recovery | Included | You navigate hold queues alone |
| Comprehensive account audit (all linked accounts) | Full audit across 50+ services | Limited to accounts you remember |
| Authentication hardening (every account) | Systematic replacement of SMS 2FA | Partial; easy to miss accounts |
| Device forensics for malware | Included | Not available |
| Dark web monitoring for leaked credentials | Ongoing monitoring | One-time checks at best |
| Law enforcement filing assistance | FBI IC3, FTC, police reports | You file everything yourself |
The Scale of SIM Swap Fraud, and Why Petronella Technology Group Exists
SIM swapping has grown from a niche telecom exploit into a mainstream cybercrime. The FBI's Internet Crime Complaint Center documented a sharp increase in reports, and the real numbers are likely much higher since many victims never file. Petronella Technology Group has been protecting businesses and individuals from identity-based attacks since 2002.
What Petronella Technology Group Does for SIM Swap Victims
Carrier Escalation and Number Recovery
We work directly with carrier fraud departments to expedite the reversal of unauthorized SIM swaps. Our established contacts at major carriers cut through standard support queues. We also ensure your account is locked down with PINs, port freezes, and SIM locks to prevent repeat attacks.
Full Account Audit and Credential Reset
Most people underestimate how many accounts are tied to their phone number. We systematically identify and secure every account, including email, banking, crypto exchanges, social media, cloud storage, and SaaS platforms. Every password is reset and every SMS-based 2FA is replaced with a secure alternative.
Device Forensics
SIM swaps sometimes accompany or follow malware infections. We analyze your devices for keyloggers, remote access trojans, and credential-stealing software that may have enabled the initial data gathering. If your device is compromised, recovering accounts without cleaning it first is pointless.
Dark Web Monitoring and Ongoing Protection
Your stolen credentials may already be circulating on dark web marketplaces. We monitor these channels for your email addresses, phone numbers, and financial account details. If new leaks appear, you are alerted and we act before attackers can exploit them.
