Uncle Sam will dole out up to $10 million for vital information on each of six Russian GRU officers linked to the Kremlin-backed Sandworm gang, who, according to the Feds, have plotted to carry out destructive cyber-attacks against American critical infrastructure.

Given ransomware gangs' eight-figure revenues, buying a legitimate copy to crack wouldn't even register as a cost of doing business.Ĭobalt Strike has been seen in use by, among others, the Clop ransomware gang China-based spies known in the West as APT41 and a black hat crew that targeted Germany's Bundestag in 2017. Legit keys for Cobalt Strike sell for $3,500 per seat at list price. However, one could argue that any detected Cobalt Strike communication, even the one using 'legitimate' keys, should be immediately blocked as it indicates a potentially serious breach of a network."
Svajcer added: "The good news is that any Cobalt Strike communication using these known keys can be outright blocked as malicious. As such, any discovery related to better detection of Cobalt Strike is likely to be significant." Vanja Svajcer, outreach researcher at Cisco Talos, told The Register: "Cobalt Strike has become a de-facto standard, almost Swiss army knife of a post-exploitation tool used by a wide variety of actors, both legitimate and malicious.
He intends to write further blogs explaining how network defenders can use the half-dozen identified key pairs to rapidly identify signs of network compromise. cobaltstrike.beacon_keys, and found private keys that match the recurring public keys we observed."
#COBALT STRIKE CRACK CRACKED#
cobaltstrike.beacon_keys because of cracked software… We did a search on VirusTotal for ZIP files containing file. "One of the hypotheses was reuse of file. "We were wondering what could possibly explain key reuse," said Stevens. Thus the reuse of key pairs shows that a number of malicious people are using a cracked version – and the presence of that particular key pair can flag up signs of malicious activity to alert blue teams. Legitimate installations of Cobalt Strike generate their own RSA key pair on first run of the server software, Stevens told El Reg.
#COBALT STRIKE CRACK SOFTWARE#
Inevitably, malicious people became interested in what an adversary simulation platform could do in their hands and it wasn't long before the software began presenting a genuine threat – with Cobalt Strike's authors writing a blog post in 2013 titled "How to crack Cobalt Strike AND backdoor it." (The post does also suggest that leaked versions may include a backdoor for its original authors, not that this seems to have deterred online criminals from using cracked versions of the software in later years.)
