Hunting IOCs via Microsoft Defender

1. Search SHA256 hashes with yearly tweets feed

let MaxAge = ago(30d);
let SHA256_whitelist = pack_array(
'XXX' // Some SHA256 hash you want to whitelist.
);
let TweetFeed = materialize (
    (externaldata(report:string)
    [@"https://raw.githubusercontent.com/0xDanielLopez/TweetFeed/master/year.csv"]
    with (format = "txt"))
    | extend report = parse_csv(report)
    | extend Type = tostring(report[2])
    | where Type == 'sha256'
    | extend SHA256 = tostring(report[3])
    | where SHA256 !in(SHA256_whitelist)
    | extend Tag = tostring(report[4])
    | extend Tweet = tostring(report[5])
    | project SHA256, Tag, Tweet 
);
union (
    TweetFeed
    | join (
        DeviceProcessEvents
        | where Timestamp > MaxAge
    ) on SHA256
), (
    TweetFeed
    | join (
        DeviceFileEvents
        | where Timestamp > MaxAge
    ) on SHA256
), ( 
    TweetFeed
    | join (
        DeviceImageLoadEvents
        | where Timestamp > MaxAge
    ) on SHA256
) | project Timestamp, DeviceName, FileName, FolderPath, SHA256, Tag, Tweet

2. Search IP addresses with monthly tweets feed

let MaxAge = ago(30d);
let IPaddress_whitelist = pack_array(
'XXX' // Some IP address you want to whitelist.
);
let TweetFeed = materialize (
    (externaldata(report:string)
    [@"https://raw.githubusercontent.com/0xDanielLopez/TweetFeed/master/month.csv"]
    with (format = "txt"))
    | extend report = parse_csv(report)
    | extend Type = tostring(report[2])
    | where Type == 'ip'
    | extend RemoteIP = tostring(report[3])
    | where RemoteIP !in(IPaddress_whitelist)
    | extend Tag = tostring(report[4])
    | extend Tweet = tostring(report[5])
    | project RemoteIP, Tag, Tweet 
);
union (
TweetFeed
    | join (
        DeviceNetworkEvents
    | where Timestamp > MaxAge
    ) on RemoteIP
) | project Timestamp, DeviceName, RemoteIP, Tag, Tweet

3. Search urls and domains with weekly tweets feed

let MaxAge = ago(30d);
let domain_whitelist = pack_array(
'XXX', // Some URL/Domain you want to whitelist.
);
let TweetFeed = materialize (
    (externaldata(report:string)
    [@"https://raw.githubusercontent.com/0xDanielLopez/TweetFeed/master/week.csv"]
    with (format = "txt"))
    | extend report = parse_csv(report)
    | extend Type = tostring(report[2])
    | where Type in('url','domain')
    | extend RemoteUrl = tostring(report[3])
    | where RemoteUrl !in(domain_whitelist)
    | extend Tag = tostring(report[4])
    | extend Tweet = tostring(report[5])
    | project RemoteUrl, Tag, Tweet 
);
union (
TweetFeed
    | join (
        DeviceNetworkEvents
    | where Timestamp > MaxAge
    ) on RemoteUrl
) | project Timestamp, DeviceName, RemoteUrl, Tag, Tweet
