For people interested in DNA: Here are three situations that are brewing in the DNA
community. I will lead with the Family
Tree Maker situation because I have not mentioned it before, then continue to Ancestry’s
change to the centiMorgan threshold for DNA matching to 8 cM, and then the GEDmatch/MyHeritage
breach.
#1
Family Tree Maker experienced an unrelated breach last weekend.
Ancestry has announced that Family Tree Maker’s breach did not affect
data on Ancestry.com. I am not a Family
Tree Maker user so I have not received personal information about this. Also, my regular bloggers are not talking
about it.
#2
From our meeting, Ancestry’s change to increase the centiMorgan
threshold for DNA matching to 8 cM. A summary from our June 20 Genies
minutes starts here:
Ancestry
has announced that in August of this year, it will be removing DNA matches of
fewer than 8 centiMorgan (cM). They have announced it will be late
August. It currently reports DNA
matches down to 6 cMs. What we will be getting, they say, is more accurate
reporting of segments and the length of the longest segment.
What
we will lose is access to potential matches with family trees that can be
helpful, despite the low numbers. Judith says if you wish to retain matches
with 8 or lower cMs, you will need to do one of the following:
· Assign your DNA match a color dot
· Contact the DNA match link directly
· Have a note in place for that DNA match
Where
are dots? The dots can be found on the DNA match list on the right side by the
note. They are used to assign family
connections (e.g., maternal matches = green, paternal matches = blue). There
are 24 color choices to enable sub-group matching. Matches can then be viewed
as a group. Judith suggested looking at your common ancestor lists and making
sure you have dots assigned for all, especially those as low as 6-8 cM. (end minutes)
If you have
kits for any people in older generations, that is the place to preserve the
small-segment matches. This is
especially true if you have parents, aunts, or uncles. For example, I have my mother’s brother and
my father’s brother. They have segments
similar to mine but technically they should be larger than mine. I do almost all my DNA research in their
kits.
This blogpost from Randy Seaver at Genea-Musings gives
detailed descriptions of the changes he made to preserve the small segments: https://www.geneamusings.com/2020/07/ancestrydna-changes-coming-soon-what-im.html

Indeed, she has again given very detailed instructions. You can skip to Preservation near the
end.
For the future, the DNA blogger I like for timely, concise news is Dr. Leah Larkin at https://thednageek.com/blog/. Dana has a good blog about which small-segment matches to save and especially instructions about how to save Thrulines matches.
#3 Breach at GEDmatch, a third-party DNA provider owned by Verogen. I reported that the problem on July 19 was not a security breach but now it is being reported as an “attack”. The website was down for multiple days and now the website has this message.
We have completed a thorough review of the site for security
vulnerabilities and have made changes where appropriate to ensure the security
of your data. If you note any issues that are of concern, please submit a
request tracker ticket for resolution. For our Tier 1 members we will be
extending your membership by 1 week.
They engaged
a cybersecurity consultant to identify the attacker and motive plus to secure
the GEDmatch website from future attacks.
The notification to users from Verogen is at the end of this post.
In addition,
there appears to have been a “malicious
phishing attempt” affecting GEDmatch users who downloaded their DNA from
MyHeritage to GEDmatch. So far the
assumption is that the GEDmatch attacker was able to steal email
addresses. They sent emails to
MyHeritage users with a link to a MyHeritage look-alike site asking for users
to login so they could get their passwords.
The link is to myheritaqe.com.
Hard to notice that they substituted a lower-case Q for the g in MyHeritage. MyHeritage has been promoting their two-factor authentication for quite
some time to guard against this sort of hack.
Caution: Be alert for fake emails from any of the
companies but especially one that you downloaded to GEDmatch. Change your password if you downloaded your
DNA to GEDmatch.
The MyHeritage
blogpost is here.
They are not aware of any data compromised on MyHeritage.
Also, Ancestry.com calls for us to use their security
feature called “two-step verification”.
