Devices running software from before 2013 should be upgraded immediately,&#8221; the agency warned. &#8220;Type 6 passwords should only be used if specific keys need to be encrypted and not hashed, or when Type 8 is not available (which typically implies that Type 9 is also unavailable).&#8221;<\/p>\n<p>On the absolute &#8220;Do not use&#8221; list are Type 0 (plain text), Type 4 \u2013 which uses a crippled form of PBKDF2 that&#8217;s susceptible to brute forcing \u2013 and Type 7, a Vigenere cipher that can be easily broken.<\/p>\n<p>As for other advice, the NSA recommends choosing long-form passwords and admins limiting access privileges for users more strictly, but you know that already.<\/p>\n<h3 class=\"crosshead\">\n  <span>Teams&#8217; week gets worse<\/span><br \/>\n<\/h3>\n<p>Just days after leaving some Teams users <a target=\"_blank\" href=\"https:\/\/www.theregister.com\/2022\/02\/15\/microsoft_teams_outage\/\" rel=\"noopener\">unable<\/a> to make and receive calls, thanks to a dodgy update, a new report from cloud security shop Avanan <a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/www.avanan.com\/blog\/hackers-attach-malicious-.exe-files-to-teams-conversations\">is warning<\/a> that Microsoft&#8217;s platform has been spreading malware.<\/p>\n<p>The campaign was spotted in January and is ongoing, Avanan said, and uses phished credentials to access Teams chat sessions.
