➡️ Emails appear to target actual 'Booking.com' host email addresses, which may indicate that recipient data was obtained from a previous breach - the timing is particularly relevant given the 'Booking.com' data breach last month ( see article - bbc.co.uk/news/articles/…). ➡️ While the emails appear to come from 'Booking.com', they are actually sent via compromised accounts. ➡️ Messages typically reference a “complaint” or “special request” requiring urgent action. ➡️ Links often use URL shorteners or services like 'share.google' to hide phishing pages ➡️ Goal is to steal login credentials or payment details through fake portals These phishing emails are very convincing, so extra caution is prudent - here are some steps you can take to reduce risk⤵️

Suspect "Orange" route of today with a colorful intercontinental mix of upstreams: 90.96.0.0/16 AS28708 AS134176 AS38047 AS49418 AS62255 AS28708: Orange S.A.🇫🇷 AS134176: Cloudie Limited🇨🇳 AS38047: Taiwan Telecom🇺🇸(yes, they are a Delaware corporation!)

151.217.0.0/16 AS62016 AS198198 AS42987 AS22879 AS199524 AS62016: Virgin Media 🇬🇧 AS198198: Telefonica Global Solutions 🇪🇸 AS42987: Virgin Media 🇬🇧 AS22879: Sirus, Inc 🇺🇸 AS199524: Gcore 🇳🇱 Location is Chicago. However, this case is slightly different. 151.217.0.0/16 is a "bogon", which means the network is not assigned to anyone at this time (and so nobody should be using it). After the first announcement, new (presumably fake) carriers were inserted into the BGP path as a decoy. The general modus operandi suggests that this is the same gang in action

Earlier this week @orange announced new routes taking precedence over its hijacked path, forcing the bad actors to withdraw the route: 90.98.0.0/15 AS41128 AS22541 AS29802 Bad actors (WITHDRAWN) 90.98.0.0/16 AS3215 AS5511 Orange 🇫🇷 90.99.0.0/16 AS3215 AS5511 Orange 🇫🇷 (see post from @DougMadory x.com/DougMadory/sta…) Meanwhile, the @VerizonBusiness hijacks out of AS29802 remain active. And, we’ve observed an additional suspicious route ⤵️⤵️
Spamhaus@spamhaus

Over the past 48 hours there have been some very interesting developments... The "@chartercomms" announcements for 47.1.0.0/16 and 47.2.0.0/16 have disappeared, implicitly confirming that they were hijacked. The "@Orange" announcement for AS41128 has changed - the path is now: 90.98.0.0/15 AS41128 AS22541 AS29802 AS41128: @orange 🇫🇷 AS22541: MEGALINK S.R.L.🇧🇴 AS29802: @HIVELOCITY 🇺🇸 The entire network has relocated from Chicago to Dallas (likely to the Prime Dallas Campus DFW01 datacenter). Once more the inclusion of a South-American ISP appears completely unrealistic, with the traffic between the AS29802 router (de-cix[.]dfw[.]hivelocity[.]net) and the final destination seemingly within the Dallas datacenter. But there's more....⬇️

🎰 “casino” (+78%) is the #1 trending term for new domain registrations this reporting period. Perhaps unsurprisingly, the term “casino” also saw a +122% ⬆️ increase in phishing domains observed by Spamhaus, ranking #2 in the Top 10. 🎣 Plus, a flurry of new Turkish casino-related entries: jojobet (#15), casibom (#17), and holiganbet (#19). Find out which phishing term ranks #1 in the latest Spamhaus Domain Report (Oct 2025 – March 2026): 👉 spamhaus.org/resource-hub/d… #Infosec #ThreatIntel

The lack of proper vetting of UK corporations' officers details has long been exploited by miscreants (and criticized by investigators). Thanks to recently strengthened regulation, …te.company-information.service.gov.uk/company/170221… proudly notes Davletshin's identity has been verified successfully. What remains to be sorted is the ability of bulletproof hosting operators to successfully establish shell corporations in the UK at all. 🧐 #OSINT #BulletproofHosting #Cybercrime #UK

However, it didn't take long for comeback attempts -- at this time, we link active 🇷🇺 Galeon LLC (AS211663) and aforementioned UFO TECHNOLOGIES LIMITED (AS201738) to this threat actor. Both networks trace back to St. Petersburg, Russia (and are included in our DROP and ASN-DROP lists). 👉 spamhaus.org/blocklists/do-… ⤵️

Another day, another 🇬🇧 UK-based shell corporation utilized for nefarious purposes: UFO TECHNOLOGIES LIMITED, registered to the pictured address in Ipswich (which houses a co-working space) in February. Its director, 🇷🇺 Russian national Lenar I. Davletshin, is no stranger to cybercrime investigators; related internet infrastructure and corporate entities have repeatedly been linked to bulletproof hosting. Particularly noteworthy is "Bearhost", a related, long-standing service offering, which shut down on May 9, 2025. ⤵️

UPDATE: Commencing April 19, 🇯🇵 victims came under siege from a botnet spam campaign advertising erectile dysfunction medication to them. 💊 The vast majority of these spam emitters are behind dial-up IPs at 🇨🇳 Chinese ISPs, causing a +268% XBL listing increase at China Mobile Communications Corporation's networks in particular, pushing this ISP to rank #1 of our top 10: 👉 spamhaus.org/reputation-sta… Interestingly, some emissions are also seen out of 🇹🇷 turkcell[.]com[.]tr's networks. The quality of these pills (should they be delivered at all) is anyone's guess -- from our perspective however, should they be as low-quality as the spam campaign advertising them, we'd strongly recommend against taking them. ;-) #Spam #Botnet #ReputationStatistics
Spamhaus@spamhaus

With a +338% ⬆️ increase, 🇨🇳 China-based telecoms provider “chinamobile[.]com” ranks #1 for hosting IP space associated with exploited devices, with 277,765 detections over the last 30 days. Detections on the Exploits Blocklist began rising on April 19th, with a sharp spike between April 23rd and April 24th, increasing by over 40,000 detections (from 71,377 to 111,514). 👉 spamhaus.org/reputation-sta… The network also currently has 14 Spamhaus Blocklist (SBL) listings for IPs under its responsibility. 👉 check.spamhaus.org/sbl/listings/c… #IPs #Exploits #Spamhaus #ReputationStatistics #ThreatIntel
