Researchers who revealed this flaw report that malware may be installed or may lead to value added calls being made.There is also the possibility of creating entry points for much more complex attacks.

For now, it is not known which equipment is affected and which SIM cards are vulnerable. AdaptiveMobile Security, the company thatdiscoveredthe flaw, revealed that there are at least 30 countries where the problem is present.

It has also revealed that this flaw is actively being exploited and is in most cases completely transparent to users.Once SMS is received, it starts its action silently.

A message that gives orders to the SIM card

AdaptiveMobile Security goes even further in its revelations,stated that this must be a failure created by a private company and will be serving several countries.

More information about this issue is promised soon.For now the information will be protected and will later be presented to anyone interested in this issue.

Thus is discovered another flaw in mobile devices.A simple smartphone is now the biggest victim of attacks, with new ways to be discovered every day.Simjacker appears to be a serious problem and may be difficult to eliminate.
