Qariminta iimaylka^{(Email bombing)} waa nooc ka mid ah xadgudubka intarneedka kaas oo tiro badan oo iimaylo isku mid ah loo diro ciwaan gaar ah si ay u saameeyaan nidaamka hawlgalka kombiyuutarka. Marka sanduuqa boostada ay ku soo qulqulaan fariimo aan la tirin karin oo aan la tirin karin, awoodiisu waa daalanaysaa, taasoo horseedaysa awood la'aanta helitaanka iimaylo kale. Tan waxa laga yaabaa in la sameeyo si looga hortago in dhibbanaha uu helo ama uu dareemo fariin kale oo muhiim ah boostada. Nidaam gaabis ah ama awood la'aanta in la diro ama la helo emails waxay noqon kartaa calaamad muujinaysa in email la qarxinayo. Tani waxay dhacdaa sababtoo ah nidaamka ayaa horay loogu mashquulsanaa habaynta iimaylo aan tiro lahayn.

Iimayl Bambooyin iyo Is-dhaafsi

Waxaa jira saddex qaab oo loo adeegsado qarxinta iimaylka: dirista tirada badan, isku^(Mass) xirka liiska^(List) iyo qarxinta ZIP . Dirista tirada badan^{(Mass mailing)} waxay ku lug leedahay dirida dhowr iimayl oo nuqul ah isla cinwaan laakiin si fudud ayaa lagu ogaan karaa filtarrada spamka. Midda labaad, Liisaska isku xirka^{(List linking)} , waxay ku lug leedahay lahaanshaha cinwaanka iimaylka bartilmaameedka liiska iimaylka ee kala duwan. Isticmaaluhu wuxuu had iyo jeer ka heli doonaa boostada spamka ah ee dhammaan is-diiwaangelintan oo waa inuu si gooni ah uga baxo liiska liis kasta. Bamka iimaylka ee la sameeyo iyada oo la adeegsanayo lifaaqyada kaydsan ee ^(Email)ZIP oo ay ku jiraan malaayiin iyo balaayiin xarfo ayaa loo yaqaanaa bamka ZIP^{(ZIP bombing)}. Adeegayaasha boostada ee ku hubinaya boostada software-ka-hortagga fayraska waxay u baahan doonaan xaddi badan oo awood farsamayn ah, taasoo suurtogal ah inay keento Diidmada Adeegga^{(Denial of Service)} .

Iyadoo aanad baabi'in karin fursadaha lagugu soo riday iimaylka, waxaa jira qaar ka hortag ah & tallaabooyin ilaalin ah oo aad qaadi karto si aad u yarayso saameyntooda. Waa kuwan qaar ka mid ah:

1] Isticmaal software ka-hortagga fayraska iyo dab-damiska^{(1] Use anti-virus software and firewall)} - Waxaad yareyn kartaa fursadaha lagugu soo weeraro, adigoo isticmaalaya anti-virus oo aad dhejisid dab-damis loo habeeyey si loo xaddido socodka.

Adeegso codsiyada shaandhaynta iimaylka^{(Use email filter applications)} – filtarrada iimaylka^(Email) waa xidhmooyin loo isticmaalo in lagu maareeyo iimaylada aan la rabin iyada oo la shaandhaynayo iimaylada sida ku cad ciwaanka isha. Qaar ka mid ah filtarrada iimaylka ee inta badan loo isticmaalo Mac OS waa:

• SpamSweep
• Xayndaabka
• POPFile
• AntiSpam-ka gaarka ah X5

Qalabka^(Filter) xirmada shaandhaynta ee Windows waxaa ka mid ah:

• Iimayl Chomper
• Spam Buster
• Shaandhaynta Spam Cactus
• SpamKiller

2] Adeegso Proxy Servers^{(2] Use Proxy Servers)} - Way adagtahay in la isfahamiyo oo la shaandheeyo mid kasta iyo bam kasta oo iimayl ah oo ka imanaya ciwaanada IP-ga ee kala duwan. Xaaladdan oo kale waa la yarayn karaa iyadoo la kaashanayo wakiillada wakiillada. Server-ku waa kombiyuutar ay ku xiran yihiin dhammaan kombiyuutarada kale ee shabakad gaar ah. Server-ku wuxuu leeyahay xeerar gaar ah oo lagu shaandheynayo fariimaha uu helo ee codsanaya macluumaadka iyo agabka kombayutarada ku xiran. Tani waxay gacan ka geysataa shaandheynta codsiyada xaasidnimada ah iyo fariimaha laga helo ciwaanada IP-yada ee shakiga leh ka hor inta aan loo dirin macaamiisha server-ka wakiilka.

3] Isticmaalka Hab-maamuuska Xawilaadda Boostada ee fudud (SMTP)- ^{(3] Using Simple Mail Transfer Protocol (SMTP)- )}Diidmada^(Denial) weerarrada adeegga^(Service) waxa kale oo lagu xallin karaa iyadoo la isticmaalayo SMTP oo ah hab lagu xaqiijiyo is-dhaafsiga fariimaha guud ahaan hab-maamuuska Internetka^(Internet) . Macaamiishu waxay galaan sanduuqa boostada iyaga oo isticmaalaya borotokoolka Xafiiska Boosta^{(Post Office Protocol)} ( POP ) ama Hab-raaca Galitaanka Fariinta Internetka^{(Internet Message Access Protocol)} ( IMAP ). Iyadoo loo marayo SMTP , Wakiilka Soo Gudbinta Boostada^{(Mail Submission Agent)} ayaa markaa u gudbiya boostada ama macluumaadka Wakiilka Xawilaadda Boostada^{(Mail Transfer Agent)} ( MTA ). Marka lagu xidho SMTP^(SMTP) , MTAwuxuu falanqeeyaa diiwaanka sarrifka boostada iyo cinwaanka IP-ga ee soo diraha oo diido fariinta haddii laga shakiyo. Hababka amniga^(Security) sida xaqiijinta iyo gorgortanka ayaa la farsameeyaa inta xogta la isweydaarsanayo.

Waa muhiim inaad aqoonsato isha bambaanooyinka iimaylka oo marka aad aqoonsato, waxaad u baahan tahay inaad habayso routerkaaga ama firewall-ka oo aad ka ilaaliso xidhmooyinka ka imanaya ciwaankaas.

Email Bombing and Spamming, and ways to protect yourself

Email bombing is a form of internet abuse in which massive volumes of identical emails are sent to a specific email address to affect the operating system of a computer. When the mailbox gets flooded with countless unwanted emails, its capacity gets exhausted, leading to an inability to receive further emails. This may be done to prevent the victim from receiving or noticing some other important message in their mail. A sluggish system or inability to send or receive emails can be indications of getting email bombed. This happens because the system is already pre-occupied with processing countless emails.

Email Bombing and Spamming

There are three methods of email bombing: Mass mailing, List linking and ZIP bombing. Mass mailing involves sending several duplicate emails to the same address but can be easily detected by spam filters. The second, List linking, involves subscribing the target email address to different email list subscriptions. The user would always receive spam mail from all these subscriptions and will have to manually unsubscribe from each list separately. Email bombing done using ZIP archived attachments containing millions and billions of characters is known as ZIP bombing. Mail servers checking the mail with anti-virus software would require a greater amount of processing power, possibly resulting in Denial of Service.

While you cannot eliminate the chances of being email bombed, there are some preventive & protective measures you can take to reduce their effect. Here are some of them:

1] Use anti-virus software and firewall – You can reduce the chances of being attacked, by using anti-virus and putting up a firewall configured to restrict traffic.

Use email filter applications– Email filters are packages that are used to manage unsolicited emails by filtering emails according to the source address. Some of the email filters that are commonly used for Mac OS are:

• SpamSweep
• Spamfence
• POPFile
• Personal AntiSpam X5

Filter package tools for Windows include:

• Email Chomper
• Spam Buster
• Cactus Spam Filter
• SpamKiller

2] Use Proxy Servers– It is difficult to spam and filter each and every email bomb coming from different IP addresses. Such a situation could be mitigated with the help of proxy servers. A proxy server is a computer to which all other computers in a particular network are connected. The proxy server has certain rules for filtering the messages it receives requesting for information and resources of the computers connected to it. This helps in filtering malicious requests and messages from suspicious IP addresses before they are sent to the clients of the proxy server.

3] Using Simple Mail Transfer Protocol (SMTP)- Denial of Service attacks can also be solved using SMTP which is a method of authenticating the exchange of messages across Internet protocols. The clients access their mailbox using Post Office Protocol (POP) or the Internet Message Access Protocol (IMAP). Through SMTP, the Mail Submission Agent then transfers a mail or information to the Mail Transfer Agent (MTA). On connecting to the SMTP, the MTA analyses the mail exchange record and IP address of the sender and reject the message if they are found suspicious. Security mechanisms such as authentication and negotiation are processed during the exchange of data.

It is important that you identify the source of the email bombs and once you have identified it, you need to configure your router or firewall and prevent incoming packets from that address.
