Semalt: Front-Page News On Web Security If there is anything that people can learn from the year 2016, is how they can protect themselves from hacker intrusion. In a bid to raise awareness, Frank Abagnale, the Semalt Senior Customer Success Manager, has summarized seven of the top news that shaped this year. The Dropbox Hack One attack of particular interest is the Dropbox hack, which had a significant impact on its users. It resulted in wide coverage by the media as there were millions of compromised user accounts. It is an incident that highlighted the critical need for people to use strong and unique passwords, and a campaign to ensure companies provide such a requirement for their clients. The Dyn DNS DDoS Attack Dyn is a DNS provider that fell victim to hacking on October 21 in 2016. It was done using a Mirai botnet commonly employed in IoT devices which led to the downtime of major websites. It is no secret that hackers target IoT devices due to their multiple vulnerabilities. Nevertheless, one thing that users learned from this episode is how unsafe IoT can be when got into the wrong hands. UK's Investigatory Powers Act The UK passed one of their most controversial bills, the Investigatory Powers Bill, that increases the scope of surveillance in the name of curtailing terrorism and improving security. IT authorities now have access to user logs without needing a warrant, as they remain intact in the system for twelve months. The issue raised debates concerning the government checks and balances. They also raise questions as to how far jurisdiction goes as pertains privacy. The Bitfinex Hack Cryptocurrency started receiving mass security scrutiny after hackers gained entry into the Bitfinex exchange. Even though the firm compensated its users, people began re-examining the decision to invest in Bitcoins since such types of vulnerable exchanges never offer compensation. The topic is not entirely out of the woods yet as governments and banks begin to embrace the idea of using bitcoins as a means of currency exchange in 2017. The Dirty Cow Exploit The Dirty COW Exploit is a vulnerability in Linux's kernel which allows hackers to gain administrative privileges on the computer for at least five seconds. Linus Torvalds reported that they were well aware of its existence and attempted to fix it a decade ago. It serves as an example of how old system bugs emerge as critical vulnerabilities in the contemporary digital world, warranting the continuous monitoring of the system's safety. Ransomware The year 2016 saw an increase in ransomware attacks. They targeted a range of organizations, giving a clear indication that nobody is exempt from ransomware attacks. Raising awareness on preventive measures, and security are some ways to go about preventing users from ransomware in future. DARPA's Cyber Grand Challenge The Cyber Grand Challenge by DARPA is meant to invite teams to hack and patch system vulnerabilities. These challenges have very few human interactions as they are mostly automated Future of Systems Security in 2017 There is no telling what happens in 2017. However, hackers remain on the lookout for more vulnerabilities. Hackers may advance their attacks to target Tor networks, and other exploits and using more sophisticated branding while at it. The good thing is that among the few things making headway in 2017, is security awareness.

Semalt: Vijesti na naslovnici o web sigurnosti Ako se nešto može naučiti od 2016. godine, kako se mogu zaštititi od hakerskog upada. U nastojanju da podigne svijest, Frank Abagnale, menadžer Semalt-ovog starijeg kupca, sažeo je sedam najboljih vijesti koje su se oblikovale ove godine. Dropbox Hack Jedan napad od posebnog interesa je hack Dropbox, koji je imao značajan utjecaj na njegove korisnike. To je rezultiralo širokim pokrivanjem medija s obzirom da je bilo milijuna kompromitiranih korisničkih računa. To je incident koji je istaknuo kritičnu potrebu da ljudi koriste snažne i jedinstvene lozinke i kampanju kojom kompanijama osiguravaju da takav zahtjev daju svojim klijentima. Dyn DNS DDoS napad Dyn je pružatelj DNS-a koji je postao žrtva hakiranja 21. listopada 2016. To je učinjeno korištenjem Mirai-ovog botneta koji se obično koristi u IoT uređajima što je dovelo do zastoja glavnih web stranica. Nije tajna da hakeri ciljaju IoT uređaje zbog višestruke ranjivosti. Ipak, jedna stvar koju su korisnici saznali iz ove epizode je koliko nesiguran IoT može biti kada dođe u pogrešne ruke. Zakon o istražnim ovlastima u Velikoj Britaniji Velika Britanija je usvojila jedan od njihovih najkontroverznijih zakona, Predlog zakona o istražnim silama, koji povećava opseg nadzora u ime suzbijanja terorizma i poboljšanja sigurnosti. IT vlasti sada imaju pristup evidencijama korisnika bez potrebe za potjernicom, jer ostaju netaknute u sustavu dvanaest mjeseci. Pitanje je pokrenulo rasprave o vladinim čekovima i ravnotežama. Oni također postavljaju pitanje u kojoj je mjeri nadležnost koja se odnosi na privatnost. Bitfinex sjeckanje Kripto valuta je počela primati masovni nadzor sigurnosti nakon što su hakeri ušli u razmjenu Bitfinex-a. Iako je firma nadoknadila svoje korisnike, ljudi su počeli preispitivati odluku o ulaganju u Bitcoine jer takve vrste ranjivih razmjena nikada ne nude naknadu. Tema još uvijek nije sasvim bez šume, budući da vlade i banke počinju prihvaćati ideju o upotrebi bitcoina kao sredstva razmjene valuta u 2017. godini. Iskorištava prljava krava Prljavi COW Exploit je ranjivost u Linuxu kernelu koja omogućuje hakerima stjecanje administrativnih privilegija na računalu najmanje pet sekundi. Linus Torvalds izvijestio je da su dobro svjesni njegovog postojanja i pokušali to popraviti prije desetak godina. Služi kao primjer kako stare greške u sustavu postaju kritične ranjivosti u suvremenom digitalnom svijetu, jamčeći kontinuirano nadziranje sigurnosti sustava. Ransomware U 2016. godini došlo je do povećanja broja ransomware napada. Usmjerili su se na niz organizacija, koji su jasno pokazali da nitko nije izuzet od napada ransomwarea. Podizanje svijesti o preventivnim mjerama i sigurnosti neki su načini za sprečavanje prevencije korisnika u budućnosti. DARPA-ov Cyber Grand Challenge DARPA je Cyber Grand Challenge pozvao ekipe da hakiraju i zakrpe ranjivosti sustava. Ti izazovi imaju vrlo malo ljudskih interakcija, jer su uglavnom automatizirani Budućnost sigurnosti sustava u 2017. godini Nema podataka o tome što se događa u 2017. Međutim, hakeri su u potrazi za više ranjivosti. Hakeri mogu napredovati napade da ciljaju Tor mreže i druge eksploatacije i koristeći sofisticiranije marke dok su u njoj. Dobra stvar je što je među rijetkim stvarima koje su napredovale u 2017. godini sigurnosna svijest.
