As cyber attack surface expands, consumers and companies face more risk than ever

Everyone, not just IT, must take responsibility for security and protect ‘crown jewels’

Despite a mon­u­men­tal effort to detect and deter cyber crimes, new cyber expo­sures con­tin­ue to turn up in areas of the Inter­net most used by con­sumers and com­pa­nies.

This has been true for a while now. The over­ar­ch­ing trend reflects the peren­ni­al cat-and-mouse chase in which hack­ers and scam­mers study and exploit gaps in Inter­net-cen­tric com­merce, while secu­ri­ty ven­dors react to changes in attack tac­tics and scram­ble to shore up defens­es.

Still, the scale and scope at which the bad guys con­tin­ue to inno­vate, and thus keep them­selves sev­er­al steps ahead, is astound­ing. Prin­ci­pals from end­point threat intel­li­gence ven­dor Web­root and secu­ri­ty con­sul­tan­cy EY sat down with Third­Cer­tain­ty at the recent RSA secu­ri­ty con­fer­ence to drill down on a few trou­bling proof points:

Chameleon-like mal­ware. Mali­cious soft­ware has become “over­whelm­ing­ly poly­mor­phic,” and 2015 was a record year for mal­ware and mali­cious IP address­es, web­sites and mobile apps, Web­root Vice Pres­i­dent Patrick Kennedy tells Third­Cer­tain­ty.

In 97 per­cent of the new mal­ware that Web­root detect­ed in 2015, that spe­cif­ic sam­ple was seen on only one machine. The mal­ware down­loaded to an indi­vid­ual, then mor­phed “to some­thing slight­ly dif­fer­ent in an attempt to fool end­point secu­ri­ty prod­ucts” and got through as a new file no one has seen before, Kennedy says. In the past, mal­ware didn’t morph that quick­ly, he says.

There would be a big infec­tion of a par­tic­u­lar strain of mal­ware and, at some point, the secu­ri­ty provider would pub­lish a sig­na­ture that catch­es it. That piece of mal­ware wasn’t a prob­lem any­more because every­one was get­ting infect­ed with the same file. That’s not the case any­more and is now the excep­tion. For every per­son who down­loads that file now, the mal­ware changes a bit, so it’s a unique vari­ant of mal­ware for each indi­vid­ual end­point.”

Kennedy says the mal­ware morphs every time it spreads—like a chameleon “that moves and changes very quick­ly.”

sh_web server_400Good Web servers gone bad. Web­root also report­ed an alarm­ing trend among IP address­es of Web servers that pre­vi­ous­ly showed no his­to­ry of mali­cious behav­ior. There was a big increase in the num­ber of such IP address­es that sud­den­ly were com­pro­mised and engaged in mali­cious behav­ior in 2015. More than 100,000 IP address­es dai­ly changed from a clean his­to­ry to engag­ing in mali­cious behavior—compared with 85,000 each day in 2014.

Mali­cious Web servers can boo­by-trap web­sites with dri­ve-by down­loads and malver­tis­ing to swift­ly infect and take con­trol of the com­put­ing devices of unwit­ting web­site vis­i­tors. Or they can serve as com­mand-and-con­trol cen­ters and stor­age facil­i­ties for all man­ner of cyber crim­i­nal activ­i­ty.

Kennedy says there are sev­er­al rea­sons for the rapid increase in good Web servers turn­ing bad. “It’s sim­ply becom­ing eas­i­er to take over servers and com­pro­mise machines with the broad avail­abil­i­ty of toolk­its and bot­nets for hire,” he says. “And the tech­nolo­gies for detect­ing attacks is advanc­ing, so it has forced bad actors to raise their games as well.”

The Web­root report’s “over­all mes­sage,” Kennedy says, is that “the rate of change across the threat land­scape is con­tin­u­ing to accel­er­ate. What was harm­less five min­utes ago, a day or a week ago is not a reflec­tion of the threat it might pose right now.”

sh_domain nameUntrust­wor­thy URLs. Some 30 per­cent of mali­cious URLs—specific Web pages—were host­ed in the Unit­ed States—a high­er per­cent­age than any oth­er coun­try. Chi­na is sec­ond, host­ing 11 per­cent. “Seem­ing­ly trust­wor­thy” URLs get compromised—often with­out the web­site own­ers know­ing they have been com­pro­mised, Kennedy says.

Online greet­ing card URLs were among the most fre­quent­ly com­pro­mised Web pages. Oth­er URL cat­e­gories fre­quent­ly com­pro­mised includ­ed com­mon busi­ness sites, shop­ping and trav­el sites—basically, all the sites the pub­lic views.

As a busi­ness or an indi­vid­ual user, you may unsus­pect­ing­ly be going to sites that look and act very benign but have been com­pro­mised and present a secu­ri­ty risk,” Kennedy says.

In addi­tion to legit­i­mate web­sites host­ing dri­ve-by down­loads or serv­ing up malver­tise­ments, Web­root also found that the Unit­ed States “is, by far, the largest host of phish­ing sites, with 56 per­cent of sites with­in its bor­ders.”

Tech­nol­o­gy com­pa­nies, includ­ing Google, Apple and Face­book, were tar­get­ed by more than twice as many phish­ing sites as finan­cial insti­tu­tions such as Pay­Pal, Wells Far­go and Bank of Amer­i­ca, the report revealed. The tech­nol­o­gy com­pa­nies are tar­get­ed, Web­root says, because the same login cre­den­tials are often used to access many oth­er web­sites, “result­ing in mul­ti­ple com­pro­mised accounts with each phish­ing vic­tim.”

Ran­somware surges. Ran­somware attacks have become more sophis­ti­cat­ed and a grow­ing nui­sance for orga­ni­za­tions, much more so than in the past few years, offi­cials of EY, a Unit­ed King­dom-based com­pa­ny that changed its name from Ernst & Young. Ran­somware is high­ly sophis­ti­cat­ed mal­ware that makes a user’s com­put­er files inac­ces­si­ble by lock­ing or encrypt­ing them, and then the user is asked to pay a ran­som to regain access to them.

EY recent­ly pro­vid­ed assis­tance to a glob­al com­pa­ny under attack for two weeks “with a new wave of ran­somware,” says Hen­ry Burgess, EY’s U.S. advi­so­ry ser­vices direc­tor. “They’re find­ing the anti-virus sig­na­tures can­not be updat­ed by the anti-virus sup­pli­ers as quick­ly as they need.”

Dur­ing a sev­en-day peri­od, the com­pa­ny con­tact­ed EY eight or nine times to deal with an attack that EY had to work on for about an hour each time to get under con­trol. It was “a pret­ty severe attack over a long peri­od of time and a lit­tle bit frus­trat­ing,” because the com­pa­ny “can’t keep up with it, and the ran­somware is chang­ing so quick­ly.”

Amit Jaju, EY’s exec­u­tive direc­tor of cyber foren­sics in Mum­bai, India, wrote in a com­pa­ny blog this year that “the ini­ti­a­tion process of a ran­somware is quite sim­i­lar to that of a typ­i­cal mal­ware,” but “the impact is much more ago­niz­ing for IT secu­ri­ty teams and busi­ness­es.”

Jaju said an esti­mat­ed 30 per­cent of ran­somware vic­tims pay hack­ers to regain their data.

Ran­somware is “an increas­ing threat” that’s “a form of van­dal­ism,” and it’s very dif­fi­cult to decide whether to pay a ran­som, says Ken Allan, EY’s glob­al infor­ma­tion secu­ri­ty leader. But ran­somware is only one kind of attack, and “much more atten­tion” needs to be paid to less obvi­ous cyber attacks, he says.

Such attacks can last for months, and crit­i­cal data can be tak­en out of an orga­ni­za­tion, Allan says. “That loss of data can fun­da­men­tal­ly impact the eco­nom­ic val­ue of the orga­ni­za­tion.”

Course of action. So what can com­pa­nies do? There are no “sil­ver-bul­let” solu­tions, and a com­bi­na­tion of tech­nolo­gies needs to be deployed, says Webroot’s Kennedy.

Small busi­ness­es should start by acknowl­edg­ing that “secu­ri­ty isn’t just an IT issue—it’s an every-employ­ee issue,” he says. Busi­ness­es must invest in train­ing and mak­ing employ­ees under­stand safe and risky online behav­ior, he says.

EY’s Allan advis­es orga­ni­za­tions to iden­ti­fy their most impor­tant data to pro­tect.

Any orga­ni­za­tion has lots of information—not all is of equal impor­tance,” Allan says. “So under­stand­ing what we call the “crown jewels”—the crit­i­cal assets—is a nec­es­sary first step. Then you can start to think about how to pro­tect the assets you care about most.”

Accord­ing to EY’s 2016 Glob­al Foren­sic Data Ana­lyt­ics Sur­vey, which sur­veyed 665 exec­u­tives in nine indus­tries, cyber breach­es and insid­er threats—including mali­cious insid­ers steal­ing, manip­u­lat­ing or destroy­ing data—are the fastest-grow­ing risks their com­pa­nies face.

Near­ly 70 per­cent who respond­ed to the sur­vey, which was con­duct­ed between June and Sep­tem­ber 2015, said they need to do more to improve their cur­rent anti-fraud pro­ce­dures.
