Sometimes old news came back threatening our cyber security, all because 3G/4G dongles keep in being as vulnerable as they were in the past.
In the last report issued by the SCADA Strangelove team, the authors demonstrated that 3G/4G dongles are vulnerable to several attacks, including Remote Code Execution (RCE), Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF) and integrity attacks.
The experts tested a wide range of attacks against these devices, including SIM card cloning, data interception, subscriber location, device identification, code injection, PC infection, access to user accounts on the operator’s website, and APT attacks.
The SCADA Strangelove team tested devices from various vendors, such as Huawei (two different modems and a router), Gemtek (a modem and a router), Quanta (two modems) and ZTE (one modem)
The results are disconcerting, a significant number of vulnerabilities were found in this equipment:
We will not enter in details of the attacks (or it would be a long article) for this reason I suggest you to read the report, instead I prefer to share with you the results of the tests:
In the next table are reported the attacks carried out by the experts:
Summarizing, Huawei modems with the most recent firmware updates are the ones with a better layer of security … there is still much to do with 3G/4G dongles.
