Block Chain is increasingly facing attacks from hackers and the latest being Blockchain infrastructure company Ankr, which has informed that some of its services which are being used by Polygon and Fantom, are under attack from hackers.
Taking to Twitter, Ankr revealed that the Remote Procedure Calls (RPC) services provided to Polygon and Fantom Foundation has been compromised and an investigation is on to ascertain the exact situation. Ankr also revealed that alternative RPCs have been provided as a backup measure.
RPCs is a means of communicating across different networks and a software communication program is employed for effecting the exchange of information
Polygon Under Attack
Mudit Gupta, the chief information security officer of 0xPolygon, took to Twitter to reveal that Ankr’s RPC gateway for MATIC (polygon-rpc.com) and Fantom (rpc.ftm.tools) were hit by a DNS hack. Mr. Gupta also clarified that being a third party service it has no control or access to its technicalities. Fantom another entity which uses the services of Ankr and a victim of the attack has asked its users not to use the compromised RPC.
Gupta also revealed that the company is working with Ankr to sort out the issues and also suggested users to use Alchemy RPCs until the issue is resolved. Gupta also stated that the company is also working for perfecting an in house RPC for better security and reliability.
Ambire Wallet has reported that Polygon and Fantom networks have disappeared from their wallets. Another wallet QuickSwap DEX has asked users not to use the network which has come under attack until further notice.
Extent Of Damage Not Clear
The modus operandi of the hack is as follows –Users see an error message which asks users transfer their funds to polygonapp[.]net. Then the hack transfers the user to a different page to put their seed. The extent of infiltration is not clear but the hack targeting the RPC adds to one more of the long list of chinks in the cryptocurrency armor once thought to be impenetrable.
