As 5G is now knocking at the doors, the researchers are findings several flaws in the Long Term Evolution (LTE). According to the researchers, it may allow the attacker to seize data traffic or spread of hoax SMS messages. Although in the market, the LTE is most familiar as 4G LTE it is technically 4G and not even that it is 3.95G. But still, the operators call it as 4G. With the widespread use of LTE, various finding implies and clearly show a picture of wireless networks that the consumers take for granted are not foolproof.
The researchers from Korea Advanced Institute of Science and Technology (KAIST) submitted a draft to ITPro, suggesting that they have found 51 flaws in the LTE that comprises of 15 known and previously 36 undiscovered defects. The researchers discovered the set of flaws via code testing technique, namely “fuzzing.” The flaws found by them begin from minor issues to severe vulnerabilities that might allow spying to data manipulation. The data will be shared in the conference, but before that, they planned to share their research data with the telecom operators and makers of devices so that they can overcome the flaws and fix it earlier.
LTE has set a constant standard for itself even though the 5G network is in the queue. The results are categorized into five kinds namely improper handling of the initial unprotected procedure.
- Crafted plain requests.
- Invalid integrity protection via messages.
- Messages that are replayed.
- Bypass security procedure.
They also confirmed the flaws by demonstrating proofs over the facts of attacks against operational LTE networks. The impact is to either reject the LTE service or find hoax messages or manipulate data of users.
