href=\"https:\/\/www.reddit.com\/r\/Steam\/comments\/5skfg4\/warning_regarding_a_steam_profile_related_exploit\/\" target=\"_blank\">Steam subreddit<\/a><\/strong>\u00a0has warned\u00a0about\u00a0a new cross-site scripting (XSS) vulnerability affecting profile pages on\u00a0Valve\u2019s\u00a0PC marketplace.<\/p>\n<p><strong><a href=\"https:\/\/twitter.com\/SteamDB\/status\/828977125025787904\" target=\"_blank\">SteamDB<\/a><\/strong>\u00a0confirmed the\u00a0existence of\u00a0the vulnerability and referred readers to a\u00a0<strong><a href=\"https:\/\/steamdb.info\/forum\/292\/why-an-xss-exploit-on-steamcommunitycom-is-scary\/\" target=\"_blank\">two-year-old post<\/a><\/strong>\u00a0explaining\u00a0the kinds of attacks that might be launched.<\/p>\n<p>SteamDB said an XSS attack may be used to\u00a0sell\u00a0and buy\u00a0market items using your Steam Market funds, post comments, promote group members to officers, and vote on Greenlight items.<\/p>\n<p>However, another\u00a0subreddit mod warned that the vulnerability extends beyond Steam.<\/p>\n<p>The vulnerability can reportedly be\u00a0exploited to redirect you to any non-Steam page, such as\u00a0a fake\u00a0login page to phish your username and password.<\/p>\n<p>An attacker can also manipulate elements on the page.<\/p>\n<p>According to reports, viewing someone\u2019s\u00a0profile page, or your activity feed, on the desktop or mobile versions of Steam can trigger an attack.<\/p>\n<p>To avoid falling victim, mods said community members must not click on profile links or any suspicious links, and disable JavaScript in their\u00a0browser\u2019s options.<\/p>\n<p>Valve has been\u00a0informed about the vulnerability, according to the Steam subreddit community moderators.<\/p>\n<p>If you have been affected, you must:<\/p>\n<ul>\n<li>Change your Steam Account password.<\/li>\n<li>Enable Mobile Authenticator.<\/li>\n<li>If the Authenticator is activated, deauthorise other computers on Steam Guard, then restart your modem.<\/li>\n<li>Scan your system with a malware scanner and anti-virus.<\/li>\n<\/ul>\n<p><em>This article first appeared on
