Steam flaw could let hackers crash your PC or Mac — what you need to know
Steam's desktop client for Windows, macOS and Linux is generally a pretty rubber program, simply fifty-fifty the safest programs can have potentially devastating holes in their security.
That was the case back in September, when researchers discovered 4 dangerous vulnerabilities in Valve's gaming platform. The bad news is that these flaws could have compromised your multiplayer lucifer — or your whole computer. The practiced news is that you probably already have the patch that fixes them.
- Try the best antivirus software
- Play the all-time free PC games
- Plus: Xbox Series X just trounce PS5 in the hottest game of the year
Back in September, Check Indicate, a Tel Aviv-based cybersecurity firm, discovered iv potentially very nasty vulnerabilities in Steam. Specifically, the flaws were present in Steam Sockets, a toolkit that many third-party developers apply to help their online games run smoothly on Steam.
Believe it or not, y'all probably don't need to install a new patch to protect yourself from these flaws. That's because, in all likelihood, you lot've already installed it.
Check Point alerted Valve to the vulnerabilities back in September, and Valve patched the issue ii weeks later. The companies have waited this long to say anything to ensure that malefactors couldn't take advantage of the vulnerabilities one time Check Betoken revealed them.
Steam's desktop client software on Windows, Mac and Linux patches itself automatically — as do games, especially if you lot desire to play them online. Unless you've specifically told your Steam desktop software not to download and install updates (and every bit a result have had to play everything in offline mode for the last iii months), you've nigh certainly installed the requisite set up already.
If you haven't turned Steam on in that fourth dimension, though, it'due south probably worth booting up the desktop program and installing the latest version.
How could a Steam hacker hijack your PC?
Without going into too much technical detail, the flaws ranged in severity from "high" to "critical," as they could theoretically compromise a game — or a figurer — without whatsoever input from the victim.
The attacker could simply bring together a multiplayer server, then send malicious code straight to the end-user. The user would have no choice except to accept it. Crashing a game mid-match this way would exist easy; hijacking a computer would be somewhat more difficult, merely withal inside the realm of possibility.
Since the patch came out three months ago and Steam games require you to update before you play them online, there's fortunately not much hazard involved with these particular flaws anymore.
Even better, there's no indication that they were ever exploited in the wild. Information technology's a perfect example of security companies and software providers working together to fix issues before they ever pose a direct threat to the stop-user.
On the other mitt, it's a practiced reminder that even large, popular, safe programs like Steam ofttimes have flaws lurking in the deep recesses of the code. This is probably not the last Steam vulnerability that researchers volition e'er discover, so exist smart and keep your games updated earlier you play online.
