New Iran drop from me tracking an attribution nightmare - UNK_SmudgedSerpent! A little Charming, a little Muddy, and a lot C5. Targeting policy experts with benign conversation starters, health-themed infra, OnlyOffice spoofs, and RMMs. Check out the full story www.proofpoint.com/us/blog/thre...

Proofpoint threat researchers have designed an open-source tool—named PDF Object Hashing—to track and detect the unique characteristics of PDFs used by threat actors... similar to a digital fingerprint. 🫆 We use this tool internally to help track multiple threat actors with high confidence.

Good piece covering a big burst of TA416 activity targeting European governments last week!

First public report at Recorded Future by yours truly is out! RedNovember (formerly TAG-100, a.k.a. Storm-2077) is a Chinese state-sponsored threat group focused on intelligence collection, especially on flashpoint issues of strategic interest to China. www.recordedfuture.com/research/red...

Proofpoint threat researchers have published new research identifying a new cyber-espionage campaign by #TA415 (#APT41), a China-aligned threat actor, exploiting growing uncertainty in U.S.-China economic relations. Blog: www.proofpoint.com/us/blog/thre....

🚨🇨🇳💰 New @threatinsight.proofpoint.com blog on TA415 (aka APT41) economy and trade-themed spearphishing against US govt, think tanks & academia. The campaigns used U.S.-China economic lures and spoofed the Chair of the House Select Committee on CCP competition + the US-China Business Council.

It is time the Mustang Panda moniker went the way of Winnti Group ☠️

1/ We've just released a new report uncovering new infrastructure tied to multiple activity clusters linked to the Israeli spyware vendor #Candiru across several countries. Full report: www.recordedfuture.com/research/tra...

🚨🆕🐟🍟 New blog from me and the amazing @threatinsight.proofpoint.com team covering recent activity by multiple China-aligned threat actors targeting semiconductor companies in Taiwan over the past few months: www.proofpoint.com/us/blog/thre...

New: A handful of Chinese-linked cyber espionage groups are stepping up targeting of Taiwanese semiconductor companies, per new analysis from @proofpoint.com. Campaigns include targeting of financial analysts focused on the sector as well: www.reuters.com/sustainabili...

New DISCARDED podcast drop! Join @greg-l.bsky.social and me as we talk about our fave North Korean groups, DPRK as the neglected child, TA406 and the Russian connection, and finally, the dreaded but pervasive IT worker problem podcasts.apple.com/us/podcast/c... open.spotify.com/episode/01d1...

Fun crossover blog about TA829 (RomCom) & TransferLoader with my ecrime pals @selenalarson.bsky.social it’s got it all: 🛰️ Popped routers for sending phish 📊 ACH on attribution 👾 custom protocols 👽 cool malware 🕵️ crime 🎯 espionage ❔many unanswered questions www.proofpoint.com/us/blog/thre...

🚨 We’re hiring at Recorded Future’s Insikt Group Two senior analyst roles are open right now. Both focus on tracking nation-state threats. 🧵

Today we’re publishing new findings on Predator spyware, still active despite global sanctions, now with a new client and ties to a Czech entity. Here’s what we found 🧵 www.recordedfuture.com/research/pre...

Dropping some joint research today with Threatray on TA397/Bitter 🔍 We dive into the confluence of signals that led us to our attribution of the threat actor 🎯 Shoutout to @konstantinklinger.bsky.social and Threatray for collaborating on this research. www.proofpoint.com/us/blog/thre...

From phishes to hands-on-keyboard commands 🔥 new @proofpoint.bsky.social research from @nickattfield.bsky.social and @konstantinklinger.bsky.social on Indian state-sponsored actor TA397 (Bitter) with a great story on the steps to technical and political attribution www.proofpoint.com/us/blog/thre...

Is the era of the “named actor” done? As the OG adversary sets diverge, get promoted, or move on actors dispersing across the kill chain based on specialized skills increases (ORBs, criminal underground) AND the CTI models maturing… APTs ⬇️⬇️ UNCs ⬆️⬆️

same tbh

New Proofpoint blog alert We observed DPRK actor TA406 (overlaps w/ Opal Sleet/Konni) targeting government entities in Ukraine in early 2025: www.proofpoint.com/us/blog/thre...

@greg-l.bsky.social drops knowledge on TA406 (Konni) as North Korea shows new interest in Ukraine, likely to keep tabs on the progress of the war and Russia's ability to keep pace on the battlefield www.proofpoint.com/us/blog/thre...

Had such a great time at PIVOTcon @pivotcon.bsky.social - what a brilliant conference and the location isn't half bad either 🇪🇸

If you're looking at email headers and they're not pretty, you need to install @jacoblatonis.me's @vscode.dev extension marketplace.visualstudio.com/items?itemNa...

Thanks to my favorite team buddies for their collab and indulging my slight obsession 💜 @greg-l.bsky.social @mkyo.bsky.social and Josh

Saher's first blog on the scourge that is ClickFix usage in the espionage space!! Had to sneak in the UNK_RemoteRogue RDP shenanigans as well - a thus far unattributed group we assess to be Russia-aligned, using a pretty fun set of email tactics

My first blog with Proofpoint is live! And we love a good crossover. State-sponsored actors try their hand at ClickFix - the hottest thing in cybercrime. Meet the North Koreans, Iranians, and Russians who are upping their social engineering game www.proofpoint.com/us/blog/thre...

tired of looking at email headers as disgusting plaintext? only want things of value to stand out? look no further than this VSCode extension built by @jacoblatonis.me marketplace.visualstudio.com/items?itemNa...

timmy?!?!

📣 Oops!... They did it again!!! 61 Talks submitted and so many too good that, once again, we had to increase a bit the number of accepted talks.🔥 #PIVOTcon25 Agenda is finally here, and the caliber is insane!!! Check it out➡️ pivotcon.org/agenda-2025/ #CTI #ThreatIntel Talks and presenters in🧵⬇️ 1/18

Veeeery excited to attend and present at @pivotcon.bsky.social on attributing an extremely weird campaign to China-aligned TA415 (APT41/Brass Typhoon), as well as covering subsequent targeted activity linked to this actor!

Introducing #UNK_CraftyCamel! Leveraged Trusted Business Relationship? ✅ Low Volume, highly targeted? ✅ Interesting technique? ✅ Overlaps with other IRGC clusters? ✅ Bonus: Infrastructure still up to watch how they respond to the blog? ✅ www.proofpoint.com/us/blog/thre...

if you haven't done an escape room with members of your threat research team you're missing out

If I had a dollar for every single time something is attributed vaguely to “”Mustang Panda”” I could buy a flat in London

All you random non-cyber people who started following me are going to be very confused when I post about Chinese APTs and not my dog

1/ In a recent cyber campaign, the Chinese state-sponsored group TAG-112 compromised two Tibetan websites to deliver the Cobalt Strike malware, highlighting an ongoing espionage focus on Tibetan entities: www.recordedfuture.com/research/chi...

hello bluesky but more importantly here's my dog

🚨 Chinese APT drama: Chengdu 404 (#RedGolf/#APT41) suing i-SOON (#RedHotel/#EarthLusca) over a "software development dispute" 🙃 Particularly interesting given RedHotel's use of malware families suspected to be originally developed in part by RedGolf/APT41 operators (e.g. ShadowPad/Winnti)

New from us on a Chinese APT group we track as RedHotel targeting orgs globally (overlaps Aquatic Panda/Earth Lusca/Bronze University/Red Scylla) https://www.recordedfuture.com/redhotel-a-prolific-chinese-state-sponsored-group-operating-at-a-global-scale
