The LAPSUS$ extortion group has gone quiet following a infamous and speedy rise by way of the menace panorama, concentrating on firms together with Microsoft, NVIDIA, and Okta, and incomes notoriety for its freewheeling, decentralized method to cybercrime.
Nevertheless, researchers stated the group is probably going not gone — and, in any case, its “brazen” ways might depart a legacy.
A brand new report from publicity administration specialist Tenable digs into the group’s background and the ways, methods, and procedures (TTPs) it has used, maturing from distributed denial-of-service (DDoS) assaults and web site vandalism to extra subtle strategies. These embody the usage of social engineering methods to reset person passwords and co-opt multifactor authentication (MFA) instruments.
“Characterised by erratic conduct and outlandish calls for that can’t be met — at one level, the group even accused a goal of hacking again — the LAPSUS$ group’s tenure on the forefront of the cybersecurity information cycle was chaotic,” the report notes.
Chaos, Lack of Logic A part of the Plan
“You possibly can completely name LAPSUS$ ‘slightly punk rock,’ however I attempt to keep away from making dangerous actors sound that cool,” notes Claire Tills, senior analysis engineer at Tenable. “Their chaotic and illogical approaches to assaults made it a lot tougher to foretell or put together for the incidents, usually catching defenders on the again foot.”
She explains that maybe as a result of group’s decentralized construction and crowdsourced selections, its goal profile is in every single place, which implies organizations can’t function from the “we’re not an fascinating goal” standpoint with actors like LAPSUS$.
Tills provides that it’s all the time exhausting to say whether or not a menace group has disappeared, rebranded, or simply gone quickly dormant.
“No matter whether or not the group figuring out themselves as LAPSUS$ ever claims one other sufferer, organizations can be taught invaluable classes about such a actor,” she says. “A number of different extortion-only teams have gained prominence in current months, probably impressed by LAPSUS$’s temporary and boisterous profession.”
As famous within the report, extortion teams are prone to goal cloud environments, which frequently include delicate, invaluable info that extortion teams search.
“They’re additionally usually misconfigured in ways in which provide attackers entry to such info with decrease permissions,” Tills provides. “Organizations should guarantee their cloud environments are configured with least-privilege ideas and institute sturdy monitoring for suspect conduct.”
As with many menace actors, she says, social engineering stays a dependable tactic for extortion teams, and step one many organizations might want to take is assuming they may very well be a goal.
“After that, sturdy practices like multifactor and passwordless authentication are crucial,” she explains. “Organizations should additionally repeatedly assess for and remediate known-exploited vulnerabilities, notably on digital personal community merchandise, Distant Desktop Protocol, and Energetic Listing.”
She provides that whereas preliminary entry was usually achieved by way of social engineering, legacy vulnerabilities are invaluable to menace actors when searching for to raise their privileges and transfer laterally by way of programs to realize entry to essentially the most delicate info they’ll discover.
LAPSUS$ Members Probably Nonetheless Energetic
Simply because LAPSUS$ has been quiet for months doesn’t imply the group is abruptly defunct. Cybercrime teams usually go darkish to remain out of the highlight, recruit new members, and refine their TTPs.
“We’d not be shocked to see LAPSUS$ resurface sooner or later, probably below a distinct identify in an effort to distance themselves from the infamy of the LAPSUS$ identify,” says Brad Crompton, director of intelligence for Intel 471’s Shared Providers.
He explains that although LAPSUS$ group members have been arrested, he believes the group’s communication channels will keep operational and that many companies can be focused by menace actors as soon as affiliated with the group.
“Moreover, we can also see these earlier LAPSUS$ group members develop new TTPs or probably create spinoffs of the group with trusted group members,” he says. “Nevertheless, these are unlikely to be public teams and can most likely enact a better diploma of operational safety, in contrast to their predecessors.”
Cash because the Essential Motivator
Casey Ellis, founder and CTO at Bugcrowd, a crowdsourced cybersecurity supplier, explains that cybercriminals are motivated by cash whereas nation-states are motivated by nationwide targets. So, whereas LAPSUS$ is not taking part in by the foundations, its actions are considerably predictable.
“Essentially the most harmful side, in my view, is that the majority organizations have spent the final 5 or extra years creating symmetric defensive methods based mostly on menace actors with moderately well-defined definitions and targets,” he says. “When a chaotic menace actor is launched into the combination, the sport tilts and turns into uneven, and my fundamental concern about LAPSUS$ and different related actors is that defenders have not actually been getting ready for such a menace for fairly a while.” He factors out LAPSUS$ depends closely on social engineering to realize an preliminary foothold, so assessing your group’s readiness to social engineering threats, each on the human coaching and technical management ranges, is a prudent precaution to take right here.
Ellis says whereas the said targets of LAPSUS$ and Nameless/Antisec/Lulzsec are very totally different, he believes they’ll behave equally sooner or later as menace actors.
He says the evolution of Nameless within the early 2010s noticed varied subgroups and actors rise to prominence, then fade away, solely to get replaced by others that replicated and doubled down on profitable methods.
“Maybe LAPSUS$ has vanished utterly and perpetually,” he says, “however, as a defender, I would not depend on this as my main defensive technique in opposition to such a chaotic menace.”
