![]() How does sandboxing reduce the risk?Ī sandbox is essentially a tightly controlled ‘safe space’ for a program to run in. Microsoft’s introduction of a sandboxing mode at this stage can be seen as a way of keeping on top of the threat. For common-or-garden users, it’s fair to say that this particular threat is largely theoretical at this moment in time – or at least, ‘one to watch’. ![]() It’s thought likely that high-level threat actors are taking a close interest in popular commercial AV packages to add to their attack arsenal. This discovery came shortly after UK agencies who handle classified data were warned by NCSC not to use Kaspersky AV – amid fears that Russian threat actors could use it as a means of obtaining back door access. The NCSC explained how exploitation of these vulnerabilities created the possibility of planting code in the OS and taking control of the system. So far, there have been no reported instances of in-the-wild attackers successfully targeting Windows Defender Antivirus.īut last year, the UK’s National Computer Security Centre (NCSC) flagged up a couple of bugs in the Windows Defender core (bugs that were quickly patched by Microsoft). If the AV software was to be compromised and malware was activated, such malware could potentially run with impunity, granting the attacker access right across the system. ![]() For one thing, because they comprise multiple internal components necessary for examining such a wide range of data and file types, AV subsystems offer up a large attack surface.
