What’s 3AM?
3AM (also referred to as ThreeAM) is a ransomware group that first emerged in late 2023. Like different ransomware threats, 3AM exfiltrates victims’ knowledge (threatening to launch it publicly until a ransom is paid) and encrypts the copies left on focused organisations’ laptop techniques.
So it is the traditional story with ransomware – exfiltrate, encrypt, extort?
Just about – however there are some notable facets of 3AM which can be worthy of mentioning.
Akin to what?
The 3AM ransomware is uncommon in a lot it’s written in Rust. The Rust programming language was in all probability chosen by the ransomware’s creators as a result of it prioritises efficiency.
Why does pace matter?
When you have doubtlessly hundreds of thousands of recordsdata to encrypt throughout a sufferer’s community, pace issues so much. The longer you are taking to steal and garble your sufferer’s knowledge, the higher the prospect your assault is likely to be seen whereas it is occurring and disrupted.
The rest notable concerning the 3AM ransomware?
The 3AM ransomware renames encrypted recordsdata so that they have a “.threeamtime” extension and provides a marker string of “0x666”. It additionally wipes Quantity Shadow copies to make restoration harder for victims. Moreover, it seems that 3AM was initially developed as a “backup” for the infamous LockBit ransomware.
What do you imply by “backup”?
Not “backup” as in a “backup of your knowledge” sadly however relatively as a “backup plan”. It seems that 3AM would typically be deployed when a LockBit ransomware assault was not efficiently deployed.
As I recall LockBit had connections with Russia. So is that true of 3AM too?
Sure, that is proper. The authorities have named Dmitry Khoroshev, a Russian nationwide, because the administrator of LockBit and even offered a US $10 million reward for data resulting in his arrest. The cybercriminals behind 3AM seem to have robust hyperlinks to LockBit, communicate Russian, and principally goal Western-affiliated nations. 3AM has additionally been linked to the BlackSuit ransomware.
I see. So how will I do know if my techniques have been attacked with the 3AM ransomware?
3AM drops a ransom word on attacked techniques, warning victims that their delicate knowledge has been stolen and proposing “a deal” to stop it from being offered on the darkish net.
Who has been bit by the 3AM ransomware?
Numerous organisations have fallen foul of three AM, together with New York’s Brunsick Hospital Center, a Louisiana-based HVAC firm, and the city of Hoboken. The latter of these not solely noticed social safety numbers, driver’s licenses, payroll, well being and different private knowledge of Hoboken employees and residents leaked, but in addition erotic quick tales discovered on an worker’s laptop.
Ouch! That is embarrassing. Presumably, 3AM will launch the stolen knowledge if no cost is made?
I am afraid that does look like the case. 3AM’s darkish net leak website lists previous victims and consists of hyperlinks to the delicate stolen knowledge.
So, what motion ought to I take proper now?
The very best factor to do is to make sure that you will have hardened your defences earlier than ransomware strikes. It might be sensible to observe Tripwire’s common recommendations on how to protect your organisation from ransomware. These embody:
